Description

Apparatus for mooring and buffering}

The present invention relates to mooring and buffering devices.

A ship or offshore structure may be moored to a quay wall, another vessel or offshore structure during navigation.

Ships or marine structures are usually moored to quay walls, etc. by multiple mooring lines. The mooring line can be fixed to the quay wall, etc., by tying it to a bollard typically formed on the quay wall.

When a ship or offshore structure is moored to another ship or offshore structure, a fender is used to cushion the impact that occurs between the two ships or offshore structures.

In this case, when the fender cushions the impact between the two ships or the ocean structure, friction occurs between the fender and the two ships or the ocean structure due to the relative motion between the two ships or the ocean structure, and this friction causes Problems arise where the surface coating of the structure is damaged.

The mooring unit 120 connects the floating structure 20 and the base portion 110 when the support structure 10 and the floating structure 20 are moored to each other as shown in FIG. 2.

The mooring unit 120 is rotatably supported on the base portion 110 through a first hinge shaft H1 extending in the front and rear direction. In this case, the mooring unit 120 operates when the floating structure 20 and the base portion 110 move relative to each other in the vertical direction (i.e., when the support structure 10 and the floating structure 20 move relative to each other in the vertical direction). ) By rotating around the first hinge axis (H1), even when the support structure 10 and the floating structure 20 move relative to each other, they are not damaged and the floating structure 20 and the base portion 110 can be stably connected. there is.

In this case, the other end of the elastic part 121 facing the floating structure 20 may rotate in the vertical direction around the first hinge axis H1 (see the dotted line arrow in FIG. 3).

The elastic part 121 can expand and contract in response to the gap between the floating structure 20 and the base part 110.

More specifically, when the gap between the floating structure 20 and the base portion 110 is relatively large, the expansion portion 121 may perform an expansion operation in which the other end moves away from the base portion 110. In this case, the mooring unit 120 may increase in length.

Alternatively, when the gap between the floating structure 20 and the base portion 110 is relatively small, the expansion portion 121 may perform a contraction operation in which the other end approaches the base portion 110. In this case, the mooring unit 120 may be reduced in length.

The stretchable portion 121 may be formed in a cylindrical structure using hydraulic or pneumatic pressure, or may be formed in a telescopic structure.

One end of the attachment portion 122 facing the base portion 110 may be coupled to the elastic portion 121 and the other end facing the floating structure 20 may be attached to the floating structure 20 .

Furthermore, a number of mooring lines installed to moor conventional support structures and floating structures to each other can be reduced or omitted, so mooring work between the support structure 10 and the floating structure 20 can save manpower and time. It can be done, and it can be done safely.

The buffer roller 130 is interposed between the floating structure 20 and the base portion 110 when the support structure 10 and the floating structure 20 are moored to each other, as shown in FIGS. 2 and 4. In this case, the buffer roller 130 may be arranged to contact the floating structure 20.

The buffer roller 130 is used when the floating structure 20 and the base portion 110 approach each other (i.e., when the support structure 10 and the floating structure 20 approach each other). (110) It can cushion the impact. That is, the buffer roller 130 can cushion the impact between the support structure 10 and the floating structure 20.

The buffer roller 130 is supported on the base portion 110 so as to be rotatable about a virtual rotation center axis C extending in the forward and backward directions.

When the floating structure 20 and the base portion 110 move relative to each other in the up and down directions (i.e., when the support structure 10 and the floating structure 20 move relative to each other in the up and down directions), the buffer roller operates on the rotation center axis (C). ) can rotate around. In this case, friction between the surface of the buffer roller 130 and the floating structure 20 is reduced, and the surface coating of the floating structure 20 can be prevented from being damaged by the buffer roller 130.

For example, three buffer rollers 130 may be provided as shown in FIG. 2 . In this case, three buffer rollers 130 may be disposed between a pair of mooring units 120.

The number of buffer rollers 130 may be determined in various ways by considering the size of the base portion 110 or the buffering effect.

The movable support part 140 supports the base part 110 so as to be movable in the forward and backward directions with respect to the support structure 10. At this time, the base portion 110 moves forward and backward with respect to the support structure 10 through the movable support portion 140 when the support structure 10 and the floating structure 20 move relative to each other in the forward and backward directions. You can.

In this case, the base portion 110 is prevented from directly rubbing against the surface of the support structure 10, and the surface coating of the support structure 10 can be prevented from being damaged. Furthermore, the buffer roller 130 supported on the base portion 110 moves forward and backward with respect to the support structure 10 together with the base portion 110, so that the surface coating of the floating structure 20 is applied to the buffer roller 130. Damage can also be prevented.

In addition, the mooring unit 120 moves forward and backward with respect to the support structure 10 together with the base portion 110 when the support structure 10 and the floating structure 20 move relative to each other in the forward and backward directions, thereby supporting the support structure ( Even when 10) and the floating structure 20 move relative to each other, they are not damaged, and the floating structure 20 and the base portion 110 can be stably connected.

In this embodiment, the movable support unit 140 may include a first guide rail 141 and a pair of elastic members 142 and 143 as shown in FIG. 2.

The first guide rail 141 is formed by extending in the front-back direction on the support structure 10. In this case, the first guide rail 141 may protrude toward the floating structure 20 on the side of the support structure 10 facing the floating structure 20 .

The base portion 110 is movably coupled to the first guide rail 141. In this case, the base portion 110 may be coupled to enable sliding movement in the forward and backward direction along the first guide rail 141.

For example, the first guide rail 141 and the base portion 110 may be combined in a groove-protrusion structure extending in the front-back direction as shown in FIG. 3, but is not limited to this.

A pair of elastic members 142 and 143 are disposed on both sides of the base portion 110 as shown in FIG. 2. In other words, one of the pair of elastic members 142 and 143 may be disposed on the front side of the base portion 110, and the other may be disposed on the rear side of the base portion 110.

One end of each elastic member (142, 143) close to the base portion (110) is supported by the base portion (110), and the other end of each elastic member (142, 143) farthest from the base portion (110) is supported by the first guide rail. It can be supported in (141).

Each of the pair of elastic members 142 and 143 may be elastically deformed while the base portion 110 moves. In this case, the pair of elastic members 142 and 143 can absorb the load applied to the base portion 110 moving in the front and rear direction.

For example, the pair of elastic members 142 and 143 may be springs extending in the front-back direction, respectively, as shown in FIG. 2.

In this case, the pair of elastic members 142 and 143 may be elastically deformed in different directions while the base portion 110 moves.

In addition, although the movable support unit is not shown, it may be provided in various structures that can support the base unit to be movable in the forward and backward directions.

In the shock absorbing and mooring device 100 according to this embodiment, the base portion 110 is supported to move forward and backward on the support structure 10, and the shock absorbing roller 130 extends forward and backward on the base portion 130. By being rotatably supported around the rotation center axis C, when the support structure 10 and the floating structure 20 move relative to each other while they are moored, the surface coating of the support structure 10 and the floating structure 20 ) can prevent the surface paint from being damaged.

The contact maintenance portion 250 may maintain the contact of the buffer roller 230 with the floating structure 20 when any one of the support structure 10 and the floating structure 20 yawing.

In more detail, one of the support structure 10 and the floating structure 20 may yaoze while being moored to each other. In this case, the distance between the floating structure 20 and the base portion 210 supported by the support structure 10 in the left and right directions may vary in the front and rear directions. In other words, the distance between the front side of the floating structure 20 and the front side of the base portion 210 and the distance between the rear side of the floating structure 20 and the rear side of the base portion 210 may be different.

In this process, the buffer roller 230 is released from contact with the floating structure 20, and the effect of buffering the impact between the support structure 10 and the floating structure 20 may be reduced.

At this time, the contact maintenance unit 250 may move the buffer roller 230 so that the buffer roller 230 contacts the floating structure 20. Accordingly, the buffer roller 230 according to the present embodiment maintains a state of contact with the floating structure 20 even when one of the support structure 10 and the floating structure 20 is yawed, thereby maintaining the support structure 10 ) and the floating structure (20) can effectively cushion the impact.
