The elastic part 121 has one end facing the base part 110 and is coupled to the base part 110 through the first hinge shaft H1. In this case, the extension part 121 may rotate the other end toward the floating structure 20 around the first hinge axis H1 in the vertical direction (see dotted arrows in FIG. 3 ).

The expansion and contraction unit 121 may expand and contract according to the gap between the floating structure 20 and the base unit 110.

In more detail, when the distance between the floating structure 20 and the base unit 110 is relatively large, the expansion and contraction unit 121 may perform an expansion operation in which the other end is away from the base unit 110. In this case, the length of the mooring unit 120 may increase.

Alternatively, when the distance between the floating structure 20 and the base unit 110 is relatively small, the elastic unit 121 may perform a contraction operation in which the other end is close to the base unit 110. In this case, the length of the mooring unit 120 may be reduced.

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

The number of buffer rollers 130 may be variously determined in consideration of the size or buffer effect of the base portion 110.

The moving support part 140 supports the base part 110 so as to be movable in the front-rear direction with respect to the support structure 10. At this time, the base part 110 moves in the forward and backward directions with respect to the support structure 10 through the moving support part 140 when the support structure 10 and the floating structure 20 move in a relative motion in the forward and backward directions while the support structure 10 and the floating structure 20 are moored to each other. I can.

In this case, the base portion 110 is prevented from directly rubbing against the surface of the support structure 10, and the surface painting of the support structure 10 may be prevented from being damaged. Further, by moving the buffer roller 130 supported by the base portion 110 in the front and rear direction with respect to the support structure 10 together with the base portion 110, the surface painting of the floating structure 20 is applied to the buffer roller 130 It can also be prevented from being damaged by.

In addition, the mooring unit 120 moves in the front-rear direction with respect to the support structure 10 together with the base part 110 when the support structure 10 and the floating structure 20 move in the front-rear direction, so that the support structure ( 10) and the floating structure 20 are not damaged even when they move relative to each other, and the floating structure 20 and the base portion 110 can be stably connected.

In this embodiment, the moving support part 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 to extend in the front-rear direction to 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 unit 110 may be coupled to be slidable in the front-rear direction along the first guide rail 141.

For example, the first guide rail 141 and the base unit 110 may be coupled in a groove-protrusion structure extending in the front-rear direction as shown in FIG. 3, but is not limited thereto.

A pair of elastic members 142 and 143 are disposed on both sides around 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 at the front side of the base unit 110, and the other may be disposed at the rear side of the base unit 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 of the elastic members (142, 143) far from the base portion (110) is a first guide rail Can be supported by (141).

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

In more detail, any one of the support structure 10 and the floating structure 20 may be shaken while being moored to each other. In this case, an interval spaced apart in the left and right directions between the floating structure 20 and the base portion 210 supported by the support structure 10 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 unit 210 and the distance between the rear side of the floating structure 20 and the rear side of the base unit 210 may be different from each other.

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

In this case, the contact holding unit 250 may move the buffer roller 230 so that the buffer roller 230 contacts the floating structure 20. Therefore, the buffer roller 230 according to the present embodiment maintains a contact state with the floating structure 20 even when any one of the support structure 10 and the floating structure 20 is yawing and shakes, and thus the support structure 10 ) And the impact between the floating structure 20 can be effectively buffered.

In this working example, a plurality of buffer rollers 230 are provided, and a moving body 255 ′ in which a contact holding part 250 ′ is movably coupled to the second guide rail 211 ′ of the base part 210 ′. Including, the support structure 10 and the floating structure 20 in a state in which the floating structure 20 is moored to each other, a case where the floating structure 20 is yawing and shaking will be described as an example.

Referring to FIG. 7, the support structure 10 and the floating structure 20 may be moored to each other.

In this case, the plurality of buffer rollers 230 may each contact the floating structure 20. The moving body 255 ′ stops moving along the second guide rail 211 ′, and the other flat end may be in a state parallel to the floating structure 20.

Referring to FIG. 9, the floating structure 20 may yaw and shake.

At this time, the moving body 255 ′ is supported by the mooring unit 220 attached to the floating structure 20 to be moved along the second guide rail 211 ′. In other words, the moving body 255 ′ may move so that the other flat end is parallel to the floating structure 20.

The buffer roller 230 is supported by the moving body 255 ′ and moves, and can maintain contact with the floating structure 20.
