CHAIN COMPRESSOR AND ANCHORING DEVICE INCLUDING SAME

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/KR2024/007528 filed on May 31, 2024, which claims priority to Korean Patent Application No. 10-2023-0071354 filed on Jun. 2, 2023 and Korean Patent Application No. 10-2023-0125234 filed on Sep. 20, 2023, the entire contents of which are herein incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a chain compressor and an anchoring apparatus including the same.

BACKGROUND ART

In general, to moor a vessel, a method is used in which an anchor is lowered into the sea and fixed to the seabed. Such mooring of a vessel uses a chain compressor located on a vessel's deck, and the chain compressor may deploy or retrieve the anchor into or from the sea by heaving or winding an anchor chain to which the anchor is mounted.

In the related art, to fix a chain compressor on a ship, the lower surface of the chain compressor is joined to the deck by welding.

Anchoring apparatuses such as chain compressors have a certain degree of manufacturing tolerance, and thus, even after the chain compressor is fixed in its originally designed position on the vessel, it is necessary to check the condition of the anchor chain by testing with the actual anchor chain placed on a support roller of the chain compressor, and when the movement direction of the anchor chain is not appropriate, it is necessary to change the direction of the anchor chain by adjusting the position of the chain compressor.

In this case, there is a problem in that the task of adjusting the direction of the chain compressor is cumbersome, because it is necessary to detach the chain compressor from the deck, adjust the direction of the chain compressor, and then weld the chain compressor back onto the deck of the vessel.

Furthermore, in the related art, there is a problem in that because welding between the chain compressor and the deck is repeatedly performed each time the direction of the chain compressor is adjusted, the welding causes thermal damage to the deck.

The background art of the present disclosure is disclosed in Korean Patent Registration No. 10-1001675 (registered on Dec. 9, 2010, titled: CHAIN STOPPER AND METHOD OF ADJUSTING ROLLER POSITION THEREOF).

FIG. 7 is a perspective view of an anchoring apparatus according to another embodiment of the present disclosure.

An anchor chain AC is a chain connected to an anchor that may come into contact with a seabed at a preset point to moor a vessel.

When mooring a vessel or rapidly decreasing its operating speed, the anchor chain AC may be paid out from the vessel to generate holding power by bringing the anchor into contact with the seabed, and conversely, the paid-out anchor chain AC may be retrieved onto the vessel to release the holding power for free navigation of the vessel.

Referring to FIG. 1, an anchoring apparatus 1 according to an embodiment of the present disclosure is a device for retrieving the anchor chain AC onto the vessel or paying out the anchor chain AC into the sea, and may include a chain compressor 10 and a windlass unit 20.

The chain compressor 10 is a device that fixes the position of the anchor chain AC when the anchor is in a paid-out or a retrieved state, or provides a movement path for the anchor chain AC during a process of paying out or retrieving the anchor.

Because the chain compressor 10 guides the anchor chain AC along the movement path while in contact with the heavy anchor chain AC moving at high speed, a large load may generally be applied to the chain compressor 10 by the anchor chain AC.

In particular, when the positions of the components of the anchoring apparatus 1, such as the chain compressor 10, a hawse pipe (not shown), and the windlass unit 20, which are arranged on the movement path of the anchor chain AC, are not properly aligned, the load applied to each component due to the movement of the anchor chain AC may increase.

Thus, properly aligning the position of the chain compressor 10 is required to minimize the load applied to the anchoring apparatus 1.

The chain compressor 10 and the anchoring apparatus 1 including the same according to an embodiment of the present disclosure provide a configuration that may efficiently adjust the position of the chain compressor 10, and this configuration will be described in detail below.

Referring to FIGS. 1 and 2, the chain compressor 10 according to an embodiment of the present disclosure provides a movement path for the anchor chain AC and determines the speed of movement of the anchor chain AC, and may include a base part 100, a main body part 200, a position adjustment unit 300, and a fastening member 400.

Referring to FIGS. 1 and 2, the base part 100 according to an embodiment of the present disclosure supports the main body part 200 and may be arranged between a deck D of a vessel and the main body part 200.

The base part 100 may be fixedly connected to an area of the deck D, and may be rotatably connected to the main body part 200.

Referring to FIGS. 1 and 2, the base part 100 according to an embodiment of the present disclosure may be formed to extend from the area where the main body part 200 is located to the area where the windlass unit 20 is located, and one surface of the base part 100 may be connected to one surface of the chain compressor 10 and one surface of the windlass unit 20, respectively.

The windlass unit 20 and the main body part 200 according to an embodiment of the present disclosure may be arranged on the base part 100, respectively.

The windlass unit 20 and the main body part 200 may be arranged spaced apart from each other on the base part 100, but the present disclosure is not limited thereto, and the windlass unit 20 and the main body part 200 may be arranged in various positional relationships, such as in contact with each other on the base part 100, within the technical spirit that both the windlass unit 20 and the main body part 200 are connected to one surface of the single base part 100, respectively.

In an alternative embodiment, any pair among the windlass unit 20, the base part 100, and the main body part 200 may be integrally formed with each other.

In detail, the main body part 200 may be connected to the base part 100 such that it is rotatable and movable along a preset path on the base part 100, and the windlass unit 20 may be fixedly connected to the base part 100.

As a result, the main body part 200 and the windlass unit 20 may be connected to each other via the base part 100, and thus, the chain compressor 10 and the windlass unit 20 may be modularized as a single unit.

Furthermore, because the main body part 200 is connected to the deck D of the vessel via the base part 100 instead of being directly connected to the deck D of the vessel, it is possible to prevent thermal damage to the deck D caused by repetitive welding performed during a process of adjusting the orientation of the main body part 200.

Furthermore, because the windlass unit 20 and the main body part 200 are respectively arranged on one surface of the single base part 100, the separation distance between the windlass unit 20 and the main body part 200 may be reduced, and through this, the space on the deck of the vessel where the windlass unit 20 and the main body part 200 are arranged may be utilized efficiently.

In some embodiments, by reducing the separation distance between the windlass unit 20 and the main body part 200, a jumping phenomenon of the anchor chain AC is reduced, which has the effect of allowing the anchor chain AC to be stably wound/unwound.

In detail, as the separation distance between the windlass unit 20 and the main body part 200 is reduced, there is a problem of increased interference between the windlass unit 20 and the main body part 200 in relation to the anchor chain AC. Thus, to reduce the separation distance between the windlass unit 20 and the main body part 200, precise alignment between the windlass unit 20 and the main body part 200 is required, and in this case, repetitive welding to the deck is unavoidable during a process of aligning the main body part 200, such that fire damage to the deck generally occurs.

To solve the problems described above, the base part 100 according to an embodiment of the present disclosure extends to one surface of the main body part 200 such that the base part 100 is arranged between the main body part 200 and the deck, thereby making it possible for the base part 100 to protect the deck from heat damage caused by repetitive welding.

By including the base part 100, which is connected to each of the windlass unit 20 and the main body part 200, repetitive welding for aligning the main body part 200 becomes possible, which consequently makes it possible to reduce the separation distance between the windlass unit 20 and the main body part 200 compared to the related-art anchoring apparatus.

Referring to FIGS. 2 and 4, the main body part 200 and the windlass unit 20 may be located on a longitudinal central axis CL of the base part 100, and the main body part 200 may rotate about a preset point C on the longitudinal central axis CL of the base part 100.

As a result, because the main body part 200 and the windlass unit 20 may be positioned on the same axis even before the orientation of the main body part 200 is aligned, the position of the main body part 200 may be aligned to correspond to the position of the windlass unit 20 by rotating the main body part 200 by only a relatively small angle of rotation θ, which has the effect of increasing the efficiency of the position alignment.

Furthermore, by installing the base part 100 at a preset position on the deck D, the main body part 200 and the windlass unit 20 may be installed simultaneously at the preset position.

Through this, by installing the base part 100 such that the longitudinal central axis CL of the base part 100 aligns with a virtual axis formed by an orthographic projection of the longitudinal central axis of the hawse pipe onto the deck D, the main body part 200 and the windlass unit 20 may be aligned in their proper positions, thereby increasing the efficiency of alignment for the anchoring apparatus 1.

In conclusion, because the main body part 200 and the windlass unit 20 are positioned on the same axis even before the orientation of the main body part 200 is aligned, the angle of rotation θ required for alignment is relatively reduced, thereby making it possible to decrease the number of welding operations for alignment relative to the separation distance between the main body part 200 and the windlass unit 20, and thus, compared to the related-art anchoring apparatus where the main body part 200 and the windlass unit 20 are located on different base parts 100 or only one of them is arranged on a base part 100, the present disclosure embodies the core of the technical spirit that it is advantageous to reduce the separation distance between the main body part 200 and the windlass unit 20.

That is, the chain compressor 10 and the anchoring apparatus 1 including the same according to an embodiment of the present disclosure make it possible to minimize the number and range of welding operations required to align the orientation of the main body part 200 by including components such as the base part 100 connected to the main body part 200 and the windlass unit 20, respectively, guide slots 110 for facilitating the orientation adjustment of the main body part 200, and the position adjustment unit 300, and this may be interpreted as a solution for the purpose of reducing the separation distance between the main body part 200 and the windlass unit 20 to increase the usable area of the deck of the vessel, while simultaneously reducing a jumping phenomenon of the anchor chain AC.

Referring to FIGS. 1 and 2, one surface of the main body part 200 and one surface of the windlass unit 20, which are respectively in contact with the base part 100, may be located on the same plane.

Referring to FIGS. 4 to 6, the guide slot 110 into which a fastening member 400, which will be described below, may be inserted, may be formed on one side of the base part 100 according to an embodiment of the present disclosure.

The guide slots 110 according to an embodiment of the present disclosure provide a movement path for the fastening member 400, and may include a front slot 111 and a rear slot 112.

A plurality of guide slots 110 may be provided, and may be respectively arranged on opposite sides with respect to the longitudinal central axis CL of the base part 100.

The plurality of guide slots 110 may be formed symmetrically to each other with respect to the longitudinal central axis CL of the base part 100, but the present disclosure is not limited thereto, and the plurality of guide slots 110 may be formed asymmetrically to each other.

Hereinafter, in the present specification, “front” may be interpreted as an area of the main body part 200 or the base part 100 that is opposite to the area where the windlass unit 20 is located, and “rear” may be interpreted as an area of the main body part 200 or the base part 100 that is adjacent to the windlass unit 20 in a direction opposite to the front.

In detail, the front side of the base part 100 may be interpreted as the upper side in FIG. 4, and the rear side of the base part 100 may be interpreted as an area spaced apart from the front side by a preset interval in the downward direction in FIG. 4.

Referring to FIG. 4, the front slot 111 according to an embodiment of the present disclosure may be arranged on the front side in the longitudinal direction of the base part 100 to provide a movement path for the fastening member 400.

The front slot 111 may be formed to extend along a first virtual line AX that forms a preset angle with the longitudinal central axis CL of the base part 100.

Referring to FIG. 4, the first virtual line AX may be defined such that its distance from the longitudinal central axis CL of the base part 100 increases from the front side toward the rear side in the longitudinal direction of the base part 100.

In an alternative embodiment, the first virtual line AX may be defined as a straight line, but is not limited thereto, and may be a curve defined by a preset curvature.

In an alternative embodiment, the first virtual line AX may be defined as a circular arc of a circle centered at a preset point C on the longitudinal central axis CL of the base part 100.

As a result, as the fastening member 400 is inserted into the front slot 111 and moves along the circular arc centered at the preset point C, the main body part 200, which moves integrally with the fastening member 400, may rotate about the preset point C.

In an alternative embodiment, the first virtual line AX may be defined as a straight line perpendicular to the longitudinal central axis CL of the base part 100.

In an alternative embodiment, the first virtual line AX may be defined as a straight line spaced apart from the longitudinal central axis CL of the base part 100 by a preset interval.

In an alternative embodiment, each of a plurality of front slots 111 may be formed to extend along first virtual lines AX that are defined in different shapes.

Referring to FIG. 4, a plurality of front slots 111 according to an embodiment of the present disclosure may be provided on each of one side (the left side in FIG. 4) and another side (the right side in FIG. 4) with respect to the longitudinal central axis CL of the base part 100.

As a result, when the main body part 200 and the base part 100 are temporarily fixed by welding the fastening member 400 to the front slot 111 after the position of the main body part 200 is adjusted, because the plurality of front slots 111 are provided, the welded area increases and thus the temporary fixing strength increases, which has the effect of ensuring stability during an alignment test.

The front slots 111 according to an embodiment of the present disclosure may be provided as a first front slot 111a and a second front slot 111b on the one side and the other side, respectively, with respect to the longitudinal central axis CL of the base part 100, and in detail, the first front slot 111a may be formed in an area relatively close to the longitudinal central axis CL of the base part 100, and the second front slot 111b may be formed in an area relatively far from the longitudinal central axis CL of the base part 100.

Referring to FIG. 4, according to an embodiment of the present disclosure, the first front slot 111a may be formed to extend along a first-1 virtual line AX1, and the second front slot 111b may be formed to extend along a first-2 virtual line AX2.

In an alternative embodiment, the first-1 virtual line AX1 or the first-2 virtual line AX2 may be defined as a straight line, but is not limited thereto, and may be a curve defined by a preset curvature.

In an alternative embodiment, the first-1 virtual line AX1 or the first-2 virtual line AX2 may be defined as a circular arc of a circle centered at a preset point C on the longitudinal central axis CL of the base part 100.

In detail, the first-1 virtual line AX1 and the first-2 virtual line AX2 may be defined as circular arcs of circles that have the same center C but different radii, but the present disclosure is not limited thereto, and the first-1 virtual line AX1 and the first-2 virtual line AX2 may be defined as circular arcs centered at different points C and C′ on the longitudinal central axis CL of the base part 100.

As a result, when the required angle of rotation θ of the main body part 200 is large, it is possible to rotate the main body part 200 by a large amount per unit of movement of the fastening member 400 by inserting and rotating the fastening member 400 in the front slot 111 formed along the first-1 virtual line AX1 or the first-2 virtual line AX2, which is defined as a circular arc of a circle with a small radius, whereas when the required angle of rotation θ of the main body part 200 is small, it is possible to rotate the main body part 200 by a relatively small amount per unit of movement of the fastening member 400 by inserting and rotating the fastening member 400 in the front slot 111 formed along the first-1 virtual line AX1 or the first-2 virtual line AX2, which is defined as a circular arc of a circle with a relatively large radius.

Through this, depending on the magnitude of the required angle of rotation θ of the main body part 200, the main body part 200 may be aligned effectively by selectively inserting and rotating the fastening member 400 in the first front slot 111a or the second front slot 111b.

In an alternative embodiment, the first-1 virtual line AX1 or the first-2 virtual line AX2 may be defined as a straight line perpendicular to the longitudinal central axis CL of the base part 100.

In an alternative embodiment, the first-1 virtual line AX1 or the first-2 virtual line AX2 may be defined as a straight line spaced apart from the longitudinal central axis CL of the base part 100 by a preset interval.

Each of the plurality of front slots 111 may be formed to extend along first virtual lines AX that are defined in different shapes.

In an alternative embodiment, when the plurality of front slots 111 include first to third front slots 111 on each of one side (the left side in FIG. 4) and another side (the right side with reference to FIG. 4) with respect to the longitudinal central axis CL of the base part 100, the first front slot 111a may be formed to extend along a first virtual line AX defined as a straight line perpendicular to the longitudinal central axis CL of the base part 100, the second front slot 111b may be formed to extend along a first virtual line AX defined as a straight line spaced apart from the longitudinal central axis CL of the base part 100 by a preset interval, and the third front slot 111 may be formed to extend along a first virtual line AX defined as a circular arc of a circle centered at a preset point C on the longitudinal central axis CL of the base part 100.

As a result, during a process of aligning the position of the main body part 200, when it is necessary to change the position of the main body part 200 toward the one side or the other side with respect to the longitudinal central axis CL of the base part 100, the main body part 200 may be guided along a movement path by inserting the fastening member 400 into the first front slot 111a, and when it is necessary to adjust the separation distance between the main body part 200 and the windlass unit 20, the main body part 200 may be guided along a movement path by inserting the fastening member 400 into the second front slot 111b, and when it is necessary to rotate the main body part 200 by the preset angle of rotation θ, the main body part 200 may be guided along a rotation path by inserting the fastening member 400 into the third front slot 111.

Referring to FIG. 4, the front slot 111 according to an embodiment of the present disclosure may be formed in the shape of a hole passing vertically through the base part 100, but the present disclosure is not limited thereto, and the front slot 111 may be formed in various shapes, such as the shape of a groove, within the technical spirit of being able to guide the fastening member 400 along a movement path.

Referring to FIGS. 4 to 6, the rear slot 112 according to an embodiment of the present disclosure may be arranged on the rear side in the longitudinal direction of the base part 100, and may be formed in the shape of a hole or a groove to allow the fastening member 400 to be movably inserted thereinto.

In detail, as the fastening member 400 is inserted into the front slot 111 and moves, one side of the main body part 200 adjacent to the area where the front slot 111 is located may rotate/move, and the rear slot may be formed in the shape of a slot into which the fastening member 400 passing through the other side of the main body part 200 is movably inserted, such that the other side of the main body part 200 may rotate/move integrally with the one side of the main body part 200.

As a result, structural stability is secured by the fastening members 400 connecting the main body part 200 to the base part 100 at the front and rear of the base part 100, respectively, and the rear slot 112 does not restrict the movement of the fastening member 400 located at the rear, and thus, the main body part 200 may move integrally with the fastening member 400 when the fastening member 400 inserted in the front slot 111 is moved.

The rear slot 112 may be formed to extend along a second virtual line BX that forms a preset angle with the longitudinal central axis CL of the base part 100.

Referring to FIG. 4, the second virtual line BX may be defined as a straight line parallel to the longitudinal central axis CL of the base part 100.

As a result, when the first virtual line AX is defined such that its distance from the longitudinal central axis CL of the base part 100 increases from the front side toward the rear side, the position of the fastening member 400 inserted in the front slot 111 may change in one direction (the up-down direction in FIG. 4), and thus, as the rear slot 112 is formed to extend in the one direction, clearance may be provided to allow the fastening member 400 inserted in the rear slot 112 to move freely in accordance with the movement of the fastening member 400 inserted in the front slot 111.

The second virtual line BX may be defined as a straight line, but is not limited thereto, and may be a curve defined by a preset curvature.

In an alternative embodiment, the second virtual line BX may be defined as a circular arc of a circle centered at a preset point C on the longitudinal central axis CL of the base part 100.

As a result, when the first virtual line AX is formed as a circular arc centered at the preset point C, and the fastening member 400 inserted in the front slot 111 moves along the circular arc centered at the preset point C, the fastening member 400 inserted in the rear slot 112 is also movable along the arc-shaped rear slot 112, thereby allowing the main body part 200 to rotate about the preset point C.

In an alternative embodiment, the second virtual line BX may be defined as a straight line perpendicular to the longitudinal central axis CL of the base part 100.

As a result, when the first virtual line AX is defined as a straight line perpendicular to the longitudinal direction of the base part 100, the position of the fastening member 400 inserted in the front slot 111 may change in one direction (the left-right direction in FIG. 4), and thus, as the rear slot 112 is formed to extend in the one direction, clearance may be provided to allow the fastening member 400 inserted in the rear slot 112 to move freely in accordance with the movement of the fastening member 400 inserted in the front slot 111.

In an alternative embodiment, each of a plurality of rear slots 112 may be formed to extend along second virtual lines BX that are defined in different shapes.

Referring to FIG. 4, a plurality of rear slots 112 according to an embodiment of the present disclosure may be provided on each of one side (the left side in FIG. 4) and another side (the right side in FIG. 4) with respect to the longitudinal central axis CL of the base part 100.

As a result, when the main body part 200 and the base part 100 are temporarily fixed by welding the fastening member 400 to the rear slot 112 after the position of the main body part 200 is adjusted, because the plurality of rear slots 112 are provided, the welded area increases and thus the temporary fixing strength increases, which has the effect of ensuring stability during an alignment test.

The rear slots 112 according to an embodiment of the present disclosure may be provided as a first rear slot 112a and a second rear slot 112b on the one side and the other side, respectively, with respect to the longitudinal central axis CL of the base part 100, and in detail, the first rear slot 112a may be formed in an area relatively close to the longitudinal central axis CL of the base part 100, and the second rear slot 112b may be formed in an area relatively far from the longitudinal central axis CL of the base part 100.

Referring to FIG. 4, according to an embodiment of the present disclosure, the first rear slot 112a may be formed to extend along a second-1 virtual line BX1, and the second rear slot 112b may be formed to extend along a second-2 virtual line BX2.

The second-1 virtual line BX1 and the second-2 virtual line BX2 may each be defined as a straight line parallel to the longitudinal central axis CL of the base part 100.

As a result, when the first-1 virtual line AX1 or the first-2 virtual line AX2 is defined such that its distance from the longitudinal central axis CL of the base part 100 increases from the front side toward the rear side, the position of the fastening member 400 inserted in the front slot 111 may change in one direction (the up-down direction in FIG. 4), and thus, as the rear slot 112 is formed to extend in the one direction, clearance may be provided to allow the fastening member 400 inserted in the rear slot 112 to move freely in accordance with the movement of the fastening member 400 inserted in the front slot 111.

The second-1 virtual line BX1 or the second-2 virtual line BX2 may be defined as a straight line, but is not limited thereto, and may be a curve defined by a preset curvature.

In an alternative embodiment, the second-1 virtual line BX1 or the second-2 virtual line BX2 may be defined as a circular arc of a circle centered at a preset point C on the longitudinal central axis CL of the base part 100.

As a result, when the first-1 virtual line AX1 or the first-2 virtual line AX2 is formed as a circular arc centered at the preset point C, and the fastening member 400 inserted in the front slot 111 moves along the circular arc centered at the preset point C, the fastening member 400 inserted in the rear slot 112 is also movable along the arc-shaped rear slot 112, thereby allowing the main body part 200 to rotate about the preset point C.

In an alternative embodiment, the second-1 virtual line BX1 or the second-2 virtual line BX2 may be defined as a straight line perpendicular to the longitudinal central axis CL of the base part 100.

As a result, when the first-1 virtual line AX1 or the first-2 virtual line AX2 is defined as a straight line perpendicular to the longitudinal direction of the base part 100, the position of the fastening member 400 inserted in the front slot 111 may change in one direction (the left-right direction in FIG. 4), and thus, as the rear slot 112 is formed to extend in the one direction, clearance may be provided to allow the fastening member 400 inserted in the rear slot 112 to move freely in accordance with the movement of the fastening member 400 inserted in the front slot 111.

Referring to FIG. 4, according to an embodiment of the present disclosure, the length of the first rear slot 112a and the length of the second rear slot 112b may be different from each other.

In detail, the length of the second rear slot 112b, which is relatively far from the longitudinal central axis CL of the base part 100, may be greater than the length of the first rear slot 112a, which is closer to the longitudinal central axis CL of the base part 100.

As a result, when the main body part 200 rotates about the preset point C on the longitudinal central axis CL of the base part 100, the displacement of the fastening member 400 inserted in the second rear slot 112b is greater per the same angle of rotation θ, and thus, by the second rear slot 112b providing a larger movement path or clearance than the first rear slot 112a, the fastening member 400 inserted in the second rear slot 112b may move freely without its movement being restricted.

The position where the rear slot 112 is formed corresponds to the position where the front slot 111 is formed, and the shape of the rear slot 112 may correspond to the shape of the front slot 111.

The rear slot 112 according to an embodiment of the present disclosure may be formed in various shapes within the technical spirit of being able to guide the fastening member 400 inserted in the rear slot 112 through a movement path or provide clearance for the movement of the fastening member 400 inserted in the rear slot 112, such that the fastening member 400 inserted in the rear slot 112 does not restrict the rotation or movement of the main body part 200 that occurs in accordance with the movement of the fastening member 400 inserted in the front slot 111.

Referring to FIGS. 1 to 3, guide parts 150 according to an embodiment of the present disclosure provide a movement path for the position adjustment unit 300, and may be arranged on one side of the base part 100.

However, the present disclosure is not limited thereto, and the guide parts 150 may be directly connected to the deck D of the vessel.

The guide part 150 may be formed on one side of the base part 100 adjacent to a connection part 210, which will be described below, and a hole (no reference numeral assigned) through which the position adjustment unit 300 may pass may be formed in the guide part 150.

In detail, the hole may be formed such that its longitudinal central axis is perpendicular to the longitudinal central axis CL of the base part 100, and the position adjustment unit 300, when inserted into the hole, may be provided with a movement path to move along the longitudinal central axis of the hole.

The guide parts 150 may be located symmetrically to each other with respect to the longitudinal central axis CL of the base part 100. As a result, the position adjustment unit 300 may be inserted into each of the guide part 150 located on one side of the base part 100 (the right side in FIG. 3) and the guide part 150 located on another opposite side, thereby pressing the main body part 200 in two opposite directions.

The structure and position of the guide part 150 will be described in detail below in the description of the position adjustment unit 300.

Referring to FIGS. 1 and 2, the main body part 200 according to an embodiment of the present disclosure provides a movement path for the anchor chain AC, and may include a support roller 201, a support frame 202, a dog bar 203, and the connection part 210.

The support roller 201 may be rotatably connected to the support frame 202 to provide a movement path such that the anchor chain AC moves along a preset path.

The support frame 202 supports the support roller 201 and may be connected to each of the support roller 201 and the base part 100.

The dog bar 203 selectively allows movement of the anchor chain AC, and may adjust an angle formed between the support frame 202 and the dog bar 203 to allow/restrict the movement of the anchor chain AC.

Referring to FIGS. 1 to 3, on one surface of the main body part 200 that contacts the base part 100, fastening holes 211 may be provided through which the fastening members 400 may pass.

The fastening hole 211 according to an embodiment of the present disclosure may have a longitudinal central axis that coincides with the height direction of the base part 100.

As a result, because the fastening member 400 may be inserted to pass through the fastening hole 211 in one direction (the up-down direction in FIG. 1), a worker may perform a welding operation from top to bottom when welding the fastening member 400 to the main body part 200 and the base part 100, which has the effect of ensuring ease of work.

The fastening holes 211 according to an embodiment of the present disclosure may be formed on one surface of the connection part 210, corresponding to the area where the guide slot 110 is located.

The diameter of the fastening hole 211 may be equal to the outer diameter of the fastening member 400. As a result, as the fastening members 400 move, the main body part 200 in which the fastening holes 211 are formed may move integrally, and thus, the orientation of the main body part 200 may be adjusted by the movement of the fastening member 400.

The fastening member 400 and the fastening hole 211 may be coupled to each other by various methods, such as screw coupling or an interference fit, but the present disclosure is not limited thereto, and the fastening member 400 and the fastening hole 211 may be integrally formed.

Referring to FIG. 2, the fastening holes 211 according to an embodiment of the present disclosure may be provided as a front fastening hole 211a and a rear fastening hole 211b.

The front fastening hole 211a may be formed in an area corresponding to the area where the front slot 111 is located, and the fastening member 400 located at the front may pass through the front fastening hole 211a to be inserted into the front slot 111.

The rear fastening hole 211b may be formed in an area corresponding to the area where the rear slot 112 is located, and the fastening member 400 located at the rear may pass through the rear fastening hole 211b to be inserted into the rear slot 112.

Referring to FIGS. 1, 2, and 3, the position adjustment unit 300 according to an embodiment of the present disclosure adjusts the position of the main body part 200, and may be inserted into and moved within the guide part 150.

In detail, the position adjustment unit 300 may be movably connected to the guide part 150 and may come into contact with the main body part 200 to adjust the position of the main body part 200 such that the main body part 200 is capable of relative movement on the base part 100.

A plurality of position adjustment units 300 may be provided, and the plurality of position adjustment units 300 may be connected to a plurality of guide parts 150, respectively.

According to an embodiment of the present disclosure, the guide parts 150 may be located in an area facing one surface of the main body part 200 (the left surface in FIG. 5) and an area facing another surface of the main body part 200 (the right surface in FIG. 5), respectively, and the plurality of position adjustment units 300 may be movably connected to the respective guide parts 150.

Hereinafter, the guide part 150 located in the area facing the one surface of the main body part 200 is defined as a first guide part 150a, the guide part 150 located in the area facing the other surface of the main body part 200 is defined as a second guide part 150b, the position adjustment unit 300 movably connected to the first guide part 150a is defined as a first position adjustment unit 300, and the position adjustment unit 300 movably connected to the second guide part 150b is defined as a second position adjustment unit 300.

The position adjustment unit 300 may be guided through a movement path by the guide part 150 to move in a first direction (hereinafter, the first direction is defined as the rightward direction in FIG. 4) or a second direction (hereinafter, the second direction is defined as the leftward direction in FIG. 4).

Referring to FIG. 3, when the first position adjustment unit 300 moves in the first direction, the first position adjustment unit 300 may contact and press the one surface of the main body part 200. The main body part 200 is movable by receiving pressure in the first direction from the first position adjustment unit 300, and the movement path of the main body part 200 may be determined as the fastening member 400 is guided through a movement path by the guide slot 110.

When the second position adjustment unit 300 moves in the second direction, the second position adjustment unit 300 may contact and press the other surface of the main body part 200. The main body part 200 is movable by receiving pressure in the second direction from the second position adjustment unit 300, and the movement path of the main body part 200 may be determined as the fastening member 400 is guided through a movement path by the guide slot 110.

In other words, the position adjustment unit 300 may apply a driving force in the first direction or the second direction to one side of the main body part 200 or to the opposite side, and the main body part 200 receiving the driving force may move in the first direction or the second direction.

In this case, because the fastening member 400, which moves integrally with the main body part 200, has been inserted into the guide slot 110 formed along a preset path, the main body part 200, upon receiving the driving force, may rotate/move along the preset path.

As a result, because the fastening member 400, which moves integrally with the main body part 200, has been inserted into the guide slot 110 formed along a preset path, the main body part 200 may be moved along the preset path even when the position adjustment unit 300 does not precisely control the direction of the force being applied to the main body part 200, which has the effect of facilitating accurate alignment of the main body part 200.

The position adjustment unit 300 may be connected to the guide part 150 by screw coupling. As a result, by rotating the position adjustment unit 300 clockwise or counterclockwise, the position adjustment unit 300 may be moved in the first direction or the second direction, which has the effect of making it possible to apply a large pressure to the heavy main body part 200 with a relatively small force by using torque.

However, the present disclosure is not limited thereto, and the position adjustment unit 300 and the guide part 150 may be connected to each other in various ways, such as by a rack-and-pinion gear mechanism, within the technical spirit of being able to adjust the separation distance between the position adjustment unit 300 and the main body part 200.

Referring to FIGS. 2, 3, 5, and 6, the fastening member 400 according to an embodiment of the present disclosure restricts the movement of the main body part 200, and may be inserted into the base part 100 through the main body part 200.

The fastening member 400 may be formed in various shapes, such as a polygonal tube, a circular tube, or a screw, within the technical spirit of being able to simultaneously pass through the fastening hole 211 of the main body part 200 and the guide slot 110 of the base part 100.

The outer diameter of the fastening member 400 may be formed to have the same diameter as the fastening hole 211. As a result, when the fastening member 400 is inserted into the fastening hole 211 and moves along a preset path, the main body part 200, in which the fastening hole 211 is formed to be coupled to the fastening member 400 by an interference fit or screw coupling, may move integrally with the fastening member 400.

Referring to FIGS. 1 and 2, the windlass unit 20 according to an embodiment of the present disclosure provides power such that the anchor chain AC is wound, and may include a winding roller 21 and a windlass main body 22.

The winding roller 21 according to an embodiment of the present disclosure may supply, to a chain locker, the anchor chain AC received from the chain compressor 10, and may provide a driving force to enable the anchor chain AC to move along a preset path.

The windlass main body 22 according to an embodiment of the present disclosure fixes the windlass unit 20 in position on one side of the vessel, and may be rotatably connected to the winding roller 21.

Hereinafter, the operating principle and effects of the chain compressor 10 and the anchoring apparatus 1 including the same according to an embodiment of the present disclosure will be described.

In the present specification, the chronological description of the operating principle and method is for the convenience of description, and the operating principle and method described below are not limited to the described order and may be performed simultaneously.

The anchoring apparatus 1 according to an embodiment of the present disclosure is a device that retrieves/pays out the anchor chain AC to which an anchor is connected, to allow or restrict the movement of a vessel.

Because the anchor chain AC is a large and heavy metal chain, a large load is exerted on the anchoring apparatus 1 and the anchor chain AC during a process of retrieving/paying out the anchor chain AC.

To minimize the load exerted on the anchor chain AC and the anchoring apparatus 1 during the process of retrieving/paying out the anchor chain AC, the components of the anchoring apparatus 1 need to be aligned in their proper positions.

In detail, it is important to minimize the load exerted on the anchor chain AC and the components of the anchoring apparatus 1 when the anchor chain AC moves in contact with them, by performing alignments such as minimizing bends in the movement path of the anchor chain AC, ensuring that the movement path of the anchor chain AC coincides with the position of the chain compressor 10, and arranging the support roller 201, which provides the movement path for the anchor chain AC in the chain compressor 10, and the winding roller 21, which provides the movement path for the anchor chain AC in the windlass unit 20, to be on the same line.

Referring to FIGS. 1 and 2, the chain compressor 10 and the anchoring apparatus 1 including the same according to an embodiment of the present disclosure may include the base part 100 extending from the area where the main body part 200 is located to the area where the windlass unit 20 is located.

The base part 100 is arranged between the deck D of the vessel and the main body part 200, and also between the deck D of the vessel and the windlass unit 20, and may support the main body part 200 and the windlass unit 20 on the deck D of the vessel.

Unlike the related-art anchoring apparatus, the base part 100 according to an embodiment of the present disclosure is characterized in that the main body part 200 and the windlass unit 20 are sequentially arranged in a preset direction on a single base part 100 that extends in the preset direction.

In detail, the main body part 200 may be rotatably connected to one surface of a single base part 100, and the windlass unit 20 may be fixedly connected to the surface of the base part 100.

That is, by embodying the core of the technical spirit in which a base part supporting the main body part 200 and a base part supporting the windlass unit 20 are formed as an integral unit, the present disclosure may achieve the following effects.

Because it is possible to first align the base part 100 before aligning the windlass unit 20 or the main body part 200 on the deck D of the vessel, it is easy to align the main body part 200 and the windlass unit 20.

In detail, after the base part 100 is fixed in position to the deck D of the vessel such that the longitudinal central axis CL of the base part 100 coincides with a preset path, the windlass unit 20 and the main body part 200 may be aligned by arranging the windlass unit 20 and the main body part 200 on the longitudinal central axis CL of the base part 100.

In an alternative embodiment, the preset path may be defined as a virtual axis formed by an orthographic projection of the longitudinal central axis of a hawse pipe onto the deck D of the vessel.

In an alternative embodiment, the preset path may be defined as a virtual axis connecting the center of the opening of a hawse pipe and the center of the opening of a chain locker.

As a result, compared to aligning the main body part 200 and the windlass unit 20 separately, when first aligning the base part 100 and then positioning the main body part 200 and the windlass unit 20 on the base part 100, the alignment is easier because the base part 100, which is aligned along the preset path, serves as a guideline for the alignment of the main body part 200 and the windlass unit 20.

Furthermore, there is a problem of thermal damage occurring to the deck D of the vessel due to repetitive welding performed in a process of aligning the windlass unit 20 and the main body part 200 to the deck D of the vessel, but this problem may be solved according to the present disclosure because after the base part 100 is first welded to the deck D of the vessel along the preset path, the repetitive welding for alignment is confined to being performed between the base part 100, the windlass unit 20, and the main body part 200.

In some embodiments, the windlass unit 20 and the main body part 200 may be modularized as a single unit. As a result, with the windlass unit 20 and the main body part 200 fixed in position on the base part 100 such that the winding roller 21 and the support roller 201 are aligned, it is possible to align the single-modularized anchoring apparatus 1 to the deck D of the vessel, thereby ensuring ease of alignment and ease of transport.

Hereinafter, a method of aligning the main body part 200 on the base part 100 will be described in detail.

On one surface of the base part 100 that is in contact with the main body part 200, the guide slots 110 may be formed along the preset first virtual line AX and the preset second virtual line BX.

In detail, the guide slots 110 may be formed to extend along the first virtual line AX and the second virtual line BX, and the first virtual line AX and the second virtual line BX may be preset according to the required angle of rotation θ of the main body part 200, the required displacement value of the main body part 200, the shape of the main body part 200, or the like.

The fastening hole 211 may be formed on one surface of the main body part 200 corresponding to the area where the guide slot 110 is located, and the fastening member 400 may pass through the fastening hole 211 to be inserted into the guide slot 110.

The fastening hole 211 may be connected to the fastening member 400 by screw coupling or an interference fit, and as a result, when the fastening member 400 is inserted into and moves within the guide slot 110, the main body part 200, in which the fastening hole 211 is formed, may rotate/move integrally with the fastening member 400 along the movement path of the fastening member 400.

The position adjustment unit 300 may apply pressure to the main body part 200 in the first direction or the second direction, and as the fastening member 400, which moves integrally with the main body part 200 receiving the pressure in the first direction or the second direction, moves along the path on which the guide slot 110 is formed, the main body part 200 may be guided along a rotation/movement path.

As a result, even when the position adjustment unit 300 does not precisely control the direction of the pressure being applied to the main body part 200, the main body part 200 is precisely guided along a rotation/movement path by the fastening member 400 inserted in the guide slot 110, and thus may be precisely aligned.

The base part 100 may include a plurality of guide slots 110 formed to extend along different first virtual lines AX.

In this case, a worker may align the main body part 200 by passing the fastening member 400 through the fastening hole 211, which corresponds to the guide slot 110 formed to extend along a specific first virtual line AX, according to the required angle of rotation θ of the main body part 200, the required displacement value of the main body part 200, or the like.

For example, in a case in which the plurality of guide slots 110 include first to third guide slots, the first guide slot 110 may be formed to extend along a first virtual line AX defined as a straight line perpendicular to the longitudinal central axis CL of the base part 100, the second guide slot 110 may be formed to extend along a first virtual line AX defined as a straight line spaced apart from the longitudinal central axis CL of the base part 100 by a preset interval, and the third guide slot 110 may be formed to extend along a first virtual line AX defined as a circular arc of a circle centered at a preset point C on the longitudinal central axis CL of the base part 100.

In this case, during a process in which a worker aligns the position of the main body part 200, when it is necessary to change the position of the main body part 200 by a preset interval from the longitudinal central axis CL of the base part 100, the main body part 200 may be guided along a movement path by inserting the fastening member 400 into the first guide slot 110, and when it is necessary to adjust the separation distance between the main body part 200 and the windlass unit 20, the main body part 200 may be guided along a movement path by inserting the fastening member 400 into the second guide slot 110, and when it is necessary to rotate the main body part 200 by a preset angle, the main body part 200 may be guided along a rotation path by inserting the fastening member 400 into the third guide slot 110.

As described above, the worker may insert the fastening member 400 into an appropriate fastening hole 211 and guide slot 110 according to the required degree of alignment and then apply pressure to the main body part 200 in the first direction or the second direction via the position adjustment unit 300 to align the position of the main body part 200, thereby ensuring ease and precision of alignment.

Referring to FIG. 7, a chain compressor 10′and an anchoring apparatus 2 including the same according to another embodiment of the present disclosure are the same as the chain compressor 10 and the anchoring apparatus 1 including the same according to an embodiment of the present disclosure in their configuration, operating principle, and effects, except that they further include a drive unit 500 and a control unit 600, and thus, redundant descriptions will be omitted.

The drive unit 500 may receive power from an external source and transmit power to the position adjustment unit 300.

In detail, the drive unit 500 may be electrically connected to the position adjustment unit 300 or the guide part 150, and may adjust the position of the position adjustment unit 300 by providing a driving force to the position adjustment unit 300 or the guide part 150.

Referring to FIGS. 3, 5, and 7, the drive unit 500 may provide a driving force to the first position adjustment unit 300 or the first guide part 150a to move the first position adjustment unit 300 in the first direction.

As a result, the main body part 200 may receive pressure in the first direction from the first position adjustment unit 300, and thus rotate in the clockwise direction (in FIG. 5) by the required angle of rotation θ in accordance with the movement path of the fastening member 400, which moves along the shape of the guide slot 110.

Referring to FIGS. 3, 6, and 7, the drive unit 500 may provide a driving force to the second position adjustment unit 300 or the second guide part 150b to move the second position adjustment unit 300 in the second direction.

As a result, the main body part 200 may receive pressure in the second direction from the second position adjustment unit 300, and thus rotate in the counterclockwise direction (in FIG. 5) by the required angle of rotation θ in accordance with the movement path of the fastening member 400, which moves along the shape of the guide slot 110.

Referring to FIG. 7, the control unit 600 is electrically connected to the drive unit 500 and controls the driving of the drive unit 500.

In detail, the control unit 600 may receive an input of the required movement direction, displacement, angle of rotation θ, or the like for the main body part 200, and then control the driving of the drive unit 500 by transmitting an electrical signal to the drive unit 500.

In an alternative embodiment, information about a displacement value of the position adjustment unit 300 that corresponds to the required angle of rotation θ for the main body part 200 may be pre-input into the control unit 600.

For example, a relational expression f(θ°)=N may be stored, which means that when the main body part 200 needs to rotate by +θ° for alignment, the first position adjustment unit 300 needs to move by N (mm) in the first direction, and when the main body part 200 needs to rotate by −θ° for alignment, the second position adjustment unit 300 needs to move by N (mm) in the second direction.

As a result, when a worker simply inputs, into the control unit 600, a rotation value required for the alignment of the main body part 200, the drive unit 500, which is controlled by an electrical signal from the control unit 600, moves the position adjustment unit 300 by the required displacement value in the required direction, which has the effect of facilitating the alignment.

The chain compressor 10 and the anchoring apparatus 1 including the same include the position adjustment unit 300, which is capable of adjusting the position of the main body part 200 on the base part 100 that supports the main body part 200, and thus achieve the effect of facilitating alignment of the anchoring apparatus 1.

Furthermore, the chain compressor 10 and the anchoring apparatus 1 including the same include the integral base part 100 that extends from the area where the main body part 200 is located to the area where the windlass unit 20 is located, and thus achieve the effect of enabling modularization of the anchoring apparatus 1.

In conclusion, the chain compressor 10 and the anchoring apparatus 1 including the same make it possible to minimize the number and range of welding operations required to align the orientation of the main body part 200 by including components such as the base part 100 connected to each of the main body part 200 and the windlass unit 20, and the position adjustment unit 300 for facilitating alignment of the main body part 200, thereby achieving the effect of enabling a reduction in the separation distance between the main body part 200 and the windlass unit 20 while minimizing thermal damage to the deck.

Hereinafter, chain compressors 10″ and 10′″ according to other embodiments of the present disclosure will be described in detail.

It is apparent to a person of ordinary skill in the art that the configuration of the chain compressors 10″ and 10′″ according to other embodiments of the present disclosure to be described below may be applied to, combined with, or substituted for the chain compressors 10 and 10′ according to the embodiments of the present disclosure described above, or vice versa.

Furthermore, it is also apparent to a person of ordinary skill in the art that the chain compressors 10′ and 10′″ according to other embodiments of the present disclosure may be applied to, combined with, or substituted for the anchoring apparatuss 1 and 2 described above.

FIG. 8 is a perspective view of a chain compressor according to another embodiment of the present disclosure, and FIG. 9 is a plan view of the chain compressor illustrated in FIG. 8.

Referring to FIGS. 8 and 9, the chain compressor 10′ according to another embodiment of the present disclosure may include frame parts 1100, which include a first frame part 1110 and a second frame part 1120, a support roller 1200, and adjustment units 1400.

The frame parts 1100 may include the first frame part 1110 and the second frame part 1120, and the first frame part 1110 and the second frame part 1120 may be provided to be spaced apart from each other by a preset interval and to face each other. For example, the first frame part 1110 and the second frame part 1120 may be arranged to be spaced apart from each other by a preset interval on the upper deck of the bow of a vessel (not shown).

A dog bar connection part 1130 may be formed in an upper portion of the first frame part 1110 to allow a dog bar 1300 to rotate. For example, one side of the dog bar 1300 may be hinge-connected to the upper portion of the first frame part 1110 via the dog bar connection part 1130.

A dog bar rest part 1111, on which the dog bar 1300 may be rested, may be formed in an upper portion of the second frame part 1120, at a position corresponding to the dog bar connection part 1130 of the first frame part 1110.

In other words, one side of the dog bar 1300 may be rotatably coupled to the dog bar connection part 1130 of the first frame part 1110, and the other side may rest in and be supported by a recessed groove on the upper end of the second frame part 1120.

One side of the dog bar 1300 may be hinge-connected to the first frame part 1110, and the other side may be detachably connected to the second frame part 1120. By this configuration, it is possible to cause an anchor chain to be engaged or disengaged between the dog bar 1300 and the support roller 1200.

For example, with the other side of the dog bar 1300 detached from the dog bar rest part 1111 of the second frame part 1120, the dog bar 1300 may be rotated about the dog bar connection part 1130 on one side of the dog bar 1300, such that the other side of the dog bar 1300 moves far away from the dog bar rest part 1111 of the second frame part 1120.

Through this, the anchor chain supported by the support roller 1200 may be disengaged from between the dog bar 1300 and the support roller 1200. Accordingly, as the support roller 1200 rotates in one direction or the opposite direction, the anchor chain may move in the one direction or the opposite direction.

In some embodiments, one side of the dog bar 1300 may be rotated about the dog bar connection part 1130 to cause the other side of the dog bar 1300 to rest on the dog bar rest part 1111 of the second frame part 1120.

Through this, the anchor chain supported by the support roller 1200 may be engaged between the dog bar 1300 and the support roller 1200. Accordingly, the anchor chain may be prevented from moving in one direction or the opposite direction.

The support roller 1200 may be rotatably provided on a shaft member SH that passes through the first frame part 1110 and the second frame part 1120. For example, a through hole for the shaft member SH may be formed in the support roller 1200, such that the support roller 1200 may be rotatably provided on the shaft member SH that passes through the first frame part 1110 and the second frame part 1120.

The support roller 1200 may support an anchor chain (not shown) that is connected to an anchor (not shown) and wound on a windlass (not shown). To this end, a chain support groove CS may be formed on the outer circumference of the support roller 1200, and the anchor chain may be supported by the chain support groove CS on the outer circumference of the support roller 1200.

Here, the support roller 1200 may have two directions. One direction may be the axial direction of the shaft member SH inserted through the support roller 1200, and the other direction may be the direction of the chain support groove CS, which is the direction of the anchor chain.

The chain compressor 10″ according to another embodiment of the present disclosure may adjust the position and direction angle of the support roller 1200 by using two types of adjustment plates.

In more detail, the chain compressor 10″ according to another embodiment of the present disclosure may adjust the front-rear position of the support roller 1200 in the axial direction, the left-right position of the chain support groove CS, and the direction angle of the chain support groove CS, even after the frame parts 1100 have been fixed. Here, the axial direction of the support roller 1200 may be the axial direction of the shaft member SH.

The first frame part 1110 and the second frame part 1120 may further include housing parts 1140, respectively.

The housing part 1140 may support the adjustment unit 1400, which is inserted from one side and supports the shaft member SH. In some embodiments, the position and direction of the support roller 1200 may be adjusted by adjusting the type and number of adjustment plates inserted between the housing part 1140 and the adjustment unit 1400.

Here, the adjustment plates may include two types of adjustment plates. One adjustment plate may have a uniform thickness overall, and another adjustment plate may become thinner toward one side such that its two opposing surfaces form a preset angle α.

Here, the adjustment plate having a uniform thickness overall may be referred to as a first adjustment plate 1420, and the adjustment plate in which the two opposing surfaces form the preset angle α may be referred to as a second adjustment plate 1410.

Here, the preset angle α may be 1 degree (°). When the preset angle α is 1 degree (°), the direction of the chain support groove CS may be adjusted in units of 1 degree (°).

However, the present disclosure is not limited thereto, and the second adjustment plate 1410 may be manufactured with various angles as needed. In some embodiments, the second adjustment plate 1410 may be manufactured to have a plurality of preset angles α.

For example, the second adjustment plate 1410 may have angles of 0.5 degrees (°) and 1 degree (°), and by adjusting the second adjustment plate 1410, the direction angle of the chain support groove CS may be adjusted to various angles.

The structure of the housing part 1140 and a method of adjusting the position and direction angle of the support roller 1200 by using the adjustment plates will be described in detail below.

FIG. 10 is an exploded perspective view of the chain compressor illustrated in FIG. 8, FIG. 11 is a perspective view of the adjustment unit and the support roller of the chain compressor illustrated in FIG. 8, and FIGS. 12A and 12B are perspective views of the adjustment plates illustrated in FIG. 11.

Referring to FIGS. 10 and 11, the support roller 1200 may be connected to the adjustment units 1400 by the shaft member SH, which passes through the support roller 1200 and the adjustment units 1400 and rotatably supports them.

The adjustment unit 1400, which is inserted into the housing part 1140, may have adjustment plates arranged on its opposite side surfaces.

Here, the adjustment unit 1400 may include the second adjustment plate 1410, the first adjustment plate 1420, a bush part 1430, a first fixing plate 1440, and a second fixing plate 1450.

The adjustment unit 1400 may have at least one of the second adjustment plate 1410 and the first adjustment plate 1420 arranged between the bush part 1430 and the housing part 1140, and thus may adjust the position of the support roller 1200 and the direction angle of the chain support groove CS.

In more detail, in the chain compressor 10″ according to another embodiment of the present disclosure, the position of the support roller 1200 and the direction angle of the chain support groove CS may be adjusted by adjusting the type and number of adjustment plates inserted into the adjustment unit 1400.

In the chain compressor 10″ according to another embodiment of the present disclosure, a detailed method of adjusting the position of the support roller 1200 and the direction of the chain support groove CS will be described below with reference to FIGS. 13 to 16.

Furthermore, in the adjustment unit 1400, at least one of the second adjustment plate 1410 and the first adjustment plate 1420, which are arranged between the bush part 1430 and the housing part 1140, may be fixed to the bush part 1430 by using a fixing plate.

After the adjustment units 1400 are inserted into the first frame part 1110 and the second frame part 1120, the shaft member SH may be inserted through the support roller 1200, which is arranged in the space between the first frame part 1110 and the second frame part 1120, and through the first frame part 1110 and the second frame part 1120, to be supported by the frame parts 1100.

After the shaft member SH is inserted, check plate fixing grooves CPH may be arranged at an upper end of the shaft member SH, and then the shaft member SH may be fixed to the adjustment units 1400 by using the check plate fixing grooves CPH and check plates CP.

The bush part 1430 may form a through hole through which the shaft member SH passes, and support the inserted shaft member SH.

In some embodiments, the bush part 1430 may have two types of grooves formed on its upper end. One may be a second fixing plate mounting groove 1431 for securing the second fixing plate 1450 that fixedly supports the second adjustment plate 1410, and the other may be a second fixing plate separation groove 1432 for removing the second fixing plate 1450.

Here, the fixing plate for fixedly supporting the second adjustment plate 1410 may be referred to as the second fixing plate 1450, and the fixing plate for fixedly supporting the first adjustment plate 1420 may be referred to as the first fixing plate 1440.

The second fixing plate 1450 may be a plate having a curvature corresponding to the preset angle α formed by the second adjustment plate 1410.

The second fixing plate 1450 may be inserted into and supported by the second fixing plate mounting groove 1431 that is formed on the upper end of the bush part 1430 to correspond to the shape of the second fixing plate 1450. In some embodiments, opposite ends of the second fixing plate 1450, which protrude from the second fixing plate mounting groove 1431, may be inserted into and supported by a fixing groove 1411 formed on the upper end of the second adjustment plate 1410.

Through this, the second fixing plate 1450 may fix and support the bush part 1430 and the second adjustment plate 1410.

In some embodiments, the second fixing plate 1450 may have a second separation hole formed therein. Here, the second fixing plate separation groove 1432 of the bush part 1430 and the second separation hole may be installed in alignment with each other.

In this case, the second fixing plate 1450 may be accessed from outside the housing part 1140 through the second fixing plate separation groove 1432, and the second fixing plate separation groove 1432 may assist in removing the second fixing plate 1450.

In more detail, even when the first fixing plate 1440 is removed, the second fixing plate 1450 remains inserted in the bush part 1430, and thus, removal of the second fixing plate 1450 may be difficult. Here, in a case in which the second fixing plate separation groove 1432 of the bush part 1430 and the second separation hole are arranged side by side, the second fixing plate 1450 may be lifted and removed by inserting a rod, a hook, or the like into the second separation hole through the second fixing plate separation groove 1432 of the bush part 1430.

Referring to FIG. 8 along with FIGS. 10 and 11, the first fixing plate 1440 may further include a fixing part 1441, a coupling hole 1442, and a first separation hole 1443.

The fixing part 1441 protrudes to opposite sides, and may support the first adjustment plate 1420 in contact with a protrusion 1421 of the first adjustment plate 1420.

The coupling hole 1442 may be formed through the first fixing plate 1440, and the first fixing plate 1440 and the housing part 1140 may be coupled to each other via the coupling hole 1442. The coupling hole 1442 of the first fixing plate 1440 may be formed at a position corresponding to a fixing hole 1142 of the housing part 1140, and the first fixing plate 1440 may be coupled to the housing part 1140 via a member connecting the fixing hole 1142 to the coupling hole 1442, thereby preventing the first fixing plate 1440 from detaching from the housing part 1140.

In some embodiments, the first fixing plate 1440 may be arranged between the housing part 1140 and the upper surface of the bush part 1430 in which the second fixing plate 1450 is inserted, and thus may prevent the second fixing plate 1450 from detaching from the bush part 1430.

In some embodiments, the first fixing plate 1440 may further include the first separation hole 1443, and the housing part 1140 may further include a separation groove 1141 formed as a recess at a position corresponding to the first separation hole 1443.

Thus, the first fixing plate 1440 may be easily removed from the housing part 1140 by using a tool (e.g., a rod) inserted into the first separation hole 1443.

The chain compressor 10″ according to another embodiment of the present disclosure may adjust the position and direction of the support roller 1200 by using two types of adjustment plates inserted between opposite side surfaces of the housing part 1140 and the bush part 1430.

FIGS. 12A and 12B perspective views of the adjustment plates illustrated in FIG. 11.

FIG. 12A is a perspective view of the second adjustment plate 1410, and FIG. 12B is a perspective view of the first adjustment plate 1420.

Referring to FIG. 12A, the second adjustment plate 1410 may have two opposing surfaces that form a preset angle α. For example, the two opposing surfaces of the second adjustment plate 1410 may form an angle α of 1 degree (°).

Thus, the direction angle of the support roller 1200 may be adjusted by adjusting the position and number of second adjustment plates 1410.

In some embodiments, the second adjustment plate 1410 may include, at its upper end, the fixing groove 1411 that corresponds to the thickness of the second fixing plate 1450. The second adjustment plate 1410, which is inserted to adjust the position and angle α of the support roller 1200, may be connected to and supported by the second fixing plate 1450, which is inserted into the fixing groove 1411.

Here, the fixing groove 1411 located at the upper end of the second adjustment plate 1410 may be provided with a size greater than or equal to the thickness of the second fixing plate 1450 to account for manufacturing tolerances and installation errors.

Referring to FIG. 12B, the first adjustment plate 1420 may further include a protrusion 1421 for fixing the first adjustment plate 1420 by the first fixing plate 1440, and a second adjustment hole 1422 formed through the first adjustment plate 1420.

The second adjustment hole 1422 may be formed at a position corresponding to first adjustment holes 1143 provided on opposite side surfaces of the housing part 1140.

Here, the first adjustment hole 1143 provided in the housing part 1140 may have a screw thread on its inner surface.

In some embodiments, in a case in which the second adjustment plates 1410 and the first adjustment plates 1420 or the second adjustment plates 1410 are provided in combination, the second adjustment plates 1410 may be arranged on the side of the bush part 1430, and the first adjustment plates 1420 may be arranged on the side of the housing part 1140.

Thus, in a state in which the bush part 1430 and the first adjustment plates 1420 are inserted in the housing part 1140, the first adjustment hole 1143 of the housing part 1140 and the second adjustment hole 1422 of each first adjustment plate 1420 may be arranged in approximate alignment.

Accordingly, by using an adjustment bolt that passes through the first adjustment hole 1143 and the second adjustment hole 1422, a side surface of the second adjustment plate 1410 may be pressed to easily adjust the bush part 1430 or to assist in detachment of the second adjustment plate 1410.

A process of installing the chain compressor 10″ according to another embodiment of the present disclosure will be described with reference to FIG. 10, along with FIGS. 11, 12A and 12B.

The support roller 1200 may be arranged between the first frame part 1110 and the second frame part 1120, and the bush parts 1430 may be inserted from the outside of the housing parts 1140 of the first frame part 1110 and the second frame part 1120, respectively.

The shaft member SH may be inserted through the first frame part 1110, the second frame part 1120, the bush parts 1430, and the support roller 1200, to support the support roller 1200 to be rotatable.

Here, opposite sides of the shaft member SH may be fixed while protruding from the bush parts 1430. In more detail, a groove into which a part of the check plate CP may be inserted may be provided on the upper end of each of opposite sides of the shaft member SH, and the check plate CP, with a part thereof inserted in the shaft member SH, may be fixed to the bush part 1430 to prevent the shaft member SH from rotating or moving toward one side and detaching.

In a state in which the bush part 1430 is inserted in the housing part 1140, the position and direction of the support roller 1200 may be adjusted by inserting the second adjustment plate 1410 and the first adjustment plate 1420.

A detailed method of adjusting the position and direction angle of the support roller 1200 by using the second adjustment plate 1410 and the first adjustment plate 1420 will be described below with reference to FIGS. 13 to 16.

Here, in arranging the adjustment plates between the bush part 1430 and the housing part 1140, the second adjustment plates 1410 may be arranged on the side of the bush part 1430, and the first adjustment plates 1420 may be arranged on the side of the housing part 1140.

In a process of moving the position of the second adjustment plate 1410 or the bush part 1430, an adjustment bolt may be used, which passes through the first adjustment hole 1143 of the housing part 1140, or through the first adjustment hole 1143 of the housing part 1140 and the second adjustment hole 1422 of the first adjustment plate 1420.

A screw thread may be provided on the inner surface of the first adjustment hole 1143, and the bush part 1430 may be moved by rotating a bolt corresponding to the screw thread to press the bush part 1430 or the second adjustment plate 1410 with the bolt passing through the first adjustment hole 1143 of the housing part 1140, or through the first adjustment hole 1143 of the housing part 1140 and the second adjustment hole 1422 of the first adjustment plate 1420.

When the adjustment of the position and direction of the support roller 1200 using the second adjustment plates 1410 and the first adjustment plates 1420 is completed, the second adjustment plates 1410 and the first adjustment plates 1420 may be fixed to prevent them from being detached.

First, the second fixing plate 1450 may be inserted into a space between the upper end of the bush part 1430 and the housing part 1140.

Here, the second fixing plate 1450 may be a plate having a curvature, and the second fixing plate mounting groove 1431, into which the second fixing plate 1450 may be inserted, may be provided on the upper surface of the bush part 1430. In some embodiments, the fixing groove 1411, into which the second fixing plate 1450 may be inserted, may also be provided on the upper surface of the second adjustment plate 1410.

The second fixing plate 1450 may be inserted into the second fixing plate mounting groove 1431 of the bush part 1430 and the fixing groove 1411 of the second adjustment plate 1410 through the space between the upper end of the bush part 1430 and the housing part 1140.

Here, the second fixing plate 1450 may have a thickness less than the height of the second fixing plate mounting groove 1431, and may be inserted into the second fixing plate mounting groove 1431 of the bush part 1430 and the fixing groove 1411 of the second adjustment plate 1410, such that it does not protrude outward.

In some embodiments, a third height h3 of the bush part 1430, a first height h1 of the second adjustment plate 1410, and a second height h2 of the first adjustment plate 1420 may be substantially equal to each other.

In some embodiments, the height of the housing part 1140 may be greater than the third height h3 of the bush part 1430, the first height h1 of the second adjustment plate 1410, and the second height h2 of the first adjustment plate 1420.

Thus, even in a state in which the second fixing plate 1450 is in place, a space may be provided between the housing part 1140 and the upper surfaces of the bush part 1430, the second adjustment plate 1410, the second fixing plate 1450, and the first adjustment plate 1420.

Here, even in this state, the first fixing plate 1440 may be inserted into the space between the housing part 1140 and the upper surfaces of the bush part 1430, the second adjustment plate 1410, the second fixing plate 1450, and the first adjustment plate 1420.

The first fixing plate 1440 may prevent, via the fixing part 1441, the first adjustment plate 1420 from detaching outward. In more detail, when the first adjustment plate 1420 is about to detach, the protrusion 1421 of the first adjustment plate 1420 may be blocked by the fixing part 1441 of the first fixing plate 1440 and thus prevented from protruding outward.

The first fixing plate 1440 is provided between the housing part 1140 and the bush part 1430, the second adjustment plate 1410, and the second fixing plate 1450, and thus may prevent the second fixing plate 1450 from detaching.

In some embodiments, the first fixing plate 1440 may further include the coupling hole 1442, and the first fixing plate 1440 and the housing part 1140 may be coupled to each other by using the coupling hole 1442. In more detail, the first fixing plate 1440 may have the coupling hole 1442 formed at a position corresponding to a fixing hole of the housing part 1140, and the first fixing plate 1440 may be fixed to the housing part 1140 by using a member that connects the fixing hole to the coupling hole 1442.

By arranging the bush part 1430, the second adjustment plate 1410, the first adjustment plate 1420, the first fixing plate 1440, and the second fixing plate 1450 through the process described above, the chain compressor 10″ according to another embodiment of the present disclosure may sufficiently support the support roller 1200 to prevent any change in its position or direction due to external forces or vibrations, even during use of the chain compressor 10″.

In some embodiments, a situation in which the position or direction of the support roller 1200 needs to be readjusted may arise during the use of the chain compressor 10″ of the present disclosure. In this case, it may be necessary to remove the first fixing plate 1440 and the second fixing plate 1450.

For convenient removal of the first fixing plate 1440, the first fixing plate 1440 may further include the first separation hole 1443, and the housing part 1140 may further include the separation groove 1141 formed as a recess at a position corresponding to the first separation hole 1443 to prevent the first separation hole 1443 from being inserted into the housing part 1140.

When it is necessary to remove the first fixing plate 1440, the first fixing plate 1440 may be easily removed from the housing part 1140 by using a tool (e.g., a rod) inserted into the first separation hole 1443.

In some embodiments, the second fixing plate 1450 may have the second separation hole formed therein. Here, the second fixing plate separation groove 1432 of the bush part 1430 and the second separation hole may be arranged to be in approximate alignment.

When it is necessary to remove the second fixing plate 1450, the second fixing plate 1450 may be lifted and removed by inserting a tool, such as a rod or a hook, into the second separation hole from outside the bush part 1430 through the second fixing plate separation groove 1432 of the bush part 1430.

Referring to FIG. 13, in the chain compressor 10″, the area where the adjustment plates are arranged may be divided into a first region 1101 to a fourth region 1104. The first region 1101 to the fourth region 1104 may be regions resulting from arbitrarily dividing the area for the purpose of describing the present disclosure.

Here, the side on which the first region 1101 and the second region 1102 are arranged may be arbitrarily referred to as the front side, and the side on which the third region 1103 and the fourth region 1104 are arranged may be arbitrarily referred to as the rear side. In some embodiments, the side on which the first region 1101 and the third region 1103 are arranged may be referred to as the left side, and the side on which the second region 1102 and the fourth region 1104 are arranged may be referred to as the right side.

When the direction and position of the support roller 1200 arranged on the frame part 1100 are in the proper direction and position, the number and arrangement of adjustment plates in the first region 1101 to the fourth region 1104 may be symmetrical to each other.

However, the embodiment exemplarily illustrated in FIG. 13 is for the purpose of explaining adjustment of the position and direction of the support roller 1200, and is not limited to adjusting the adjustment plates in a state in which the adjustment plates are symmetrical in the respective regions. In a state in which the position and direction of the support roller 1200 require adjustment, the adjustment plates in the respective regions may be arranged asymmetrically.

An example of moving the support roller 1200 forward may be described with reference to FIG. 14.

In a case of moving the position of the axis of the support roller 1200 forward without changing the direction angle of the support roller 1200, the position of the support roller 1200 may be moved forward by adjusting the first adjustment plates 1420 without adjusting the second adjustment plates 1410.

For example, to move the position of the support roller 1200 forward without changing its direction angle, some of the first adjustment plates 1420 provided in the first region 1101 and the second region 1102, which are located on the front side, may be respectively moved to the third region 1103 and the fourth region 1104, which are located on the rear side.

Here, because the second adjustment plates 1410 form the preset angle α, the previous direction angle of the support roller 1200 may be maintained by keeping the position and number of the second adjustment plates 1410 unchanged.

Referring to FIG. 14, by moving the positions of the first adjustment plates 1420 provided in the front regions to the rear, only the position of the support roller 1200 may be moved while maintaining its direction angle (CL1->CL1′).

An example of moving the support roller 1200 to the right may be described with reference to FIG. 15.

In a case of moving the position of the axis of the support roller 1200 to the right without changing the direction angle of the support roller 1200, the position of the support roller 1200 may be moved to the right by adjusting the first adjustment plates 1420 without adjusting the second adjustment plates 1410.

For example, to move the position of the support roller 1200 to the right without changing its direction angle, some of the first adjustment plates 1420 provided in the second region 1102 and the fourth region 1104, which are located on the right side, may be respectively moved to the first region 1101 and the third region 1103, which are located on the left side.

Here, because the second adjustment plates 1410 form the preset angle α, the previous direction angle of the support roller 1200 may be maintained by keeping the position and number of the second adjustment plates 1410 unchanged.

In some embodiments, by moving the positions of the first adjustment plates 1420 located in the right regions to the left regions, only the position of the chain support groove CS of the support roller 1200 may be moved while the direction angle of the support roller 1200 is maintained (CL2->CL2′).

An example of adjusting the direction angle of the support roller 1200 may be described with reference to FIG. 16.

The direction angle of the support roller 1200 may be adjusted by using the second adjustment plates 1410.

For example, to rotate the direction angle of the support roller 1200 clockwise, some of the second adjustment plates 1410 provided in the first region 1101 and the fourth region 1104 may be moved to the second region 1102 and the third region 1103.

In some embodiments, after removing some of the second adjustment plates 1410 provided in the first region 1101 and the fourth region 1104, additional second adjustment plates 1410 may be inserted into the second region 1102 and the third region 1103.

Through this, the axis of the support roller 1200 may be rotated clockwise (CL1->CL1″), and in detail, the magnitude of the angle of rotation of the axis of the support roller 1200 may be adjusted by adjusting the number of second adjustment plates 1410.

In some embodiments, when the first adjustment plates 1420 are adjusted as illustrated in FIGS. 14 and 15 with the direction angle of the support roller 1200 having been adjusted, the position of the support roller 1200 may be moved forward, backward, leftward, or rightward, while maintaining its adjusted direction.

FIG. 17 is a plan view of a chain compressor according to an embodiment different from the embodiment illustrated in FIG. 8.

In the chain compressor 10′″ according to another embodiment of the present disclosure, descriptions common to the chain compressors 10, 10′, and 10″ according to the embodiments of the present disclosure illustrated in FIGS. 1 to 16 will be omitted, and only the differences will be described.

Referring to FIG. 17, the chain compressor 10′″ according to another embodiment of the present disclosure may include only the first adjustment plates 1420. The chain compressor 10′″ according to another embodiment of the present disclosure may move the axis of the support roller 1200 in a front-rear direction of the chain compressor 10′″ by adjusting the first adjustment plates 1420 arranged in the first region 1101 to the fourth region 1104.

Here, it is preferable that the angle formed by opposite side surfaces of the bush part 1430 of the adjustment unit 1400 in which the first adjustment plates 1420 are provided, and opposite side surfaces of the housing part 1140 of the frame part 1100 coincides with the axial direction of the support roller 1200, but the present disclosure is not limited thereto.

In the chain compressor 10′″ according to another embodiment of the present disclosure, to move the position of the support roller 1200 forward without changing its direction angle, some of the first adjustment plates 1420 provided in the first region 1101 and the second region 1102, which are located on the front side, may be respectively moved to the third region 1103 and the fourth region 1104, which are located on the rear side.

Furthermore, in the chain compressor 10′″ according to another embodiment of the present disclosure, to move the position of the support roller 1200 backward without changing its direction angle, some of the first adjustment plates 1420 provided in the third region 1103 and the fourth region 1104, which are located on the rear side, may be respectively moved to the first region 1101 and the second region 1102, which are located on the front side.

As described above, the chain compressors 10″ and 10′″ according to other embodiments of the present disclosure may easily adjust the position and direction of the support roller 1200 by using the first adjustment plate 1420 and the second adjustment plate 1410 either respectively or together.
