DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4The port tugboat anti-collision buffer structure has the advantages of buffering friction.

[0024] Specifically, the fixed part 1 comprises a hooking plate 11, a plurality of threaded rods 12 penetrating into the hooking plate 11, a rotating wheel 13 arranged on one end of the threaded rod 12, and a stop block 14 arranged on the other end of the threaded rod 12.

[0025] The fixed part 1 comprises a hooking plate 11, a plurality of threaded rods 12 penetrating into the hooking plate 11, a rotating wheel 13 arranged on one end of the threaded rod 12, and a stop block 14 arranged on the other end of the threaded rod 12.

[0026] The buffer part one 2 is arranged on the front side of the fixed part 1, and is used for buffering the forward impact force and the lateral friction force.

[0027] The mounting plate 3 is arranged on the front side of the buffer part one 2.

[0028] The buffer part two 4 is arranged on the front side of the mounting plate 3.

[0029] The buffer part two 4 is used for buffering the forward impact force and the upward and downward friction force.

[0030] In use, a plurality of the structures are sequentially assembled on the tugboat side, and the specific steps are as follows: the hooking plate 11 is sleeved on the side of the ship, and the plurality of threaded rods 12 are tightened through the rotating wheel 13, so that the stop block 14 abuts against the side of the ship, and the structure is fixed on the side of the ship. According to the structure of the side of the ship, the fixed position of the stop block 14 can be adjusted through the design of the plurality of threaded rods 12, so that it can be applied to different sides of the ship, and the applicability in use is increased. When the tugboat collides with the wharf or cargo ship, the buffer part two 4 will first contact and buffer the forward impact force and the upward and downward friction force generated, and then the buffer part one 2 will contract and buffer the forward impact force for the second time, and can also buffer the lateral friction force. Through the buffer part one 2 and the buffer part two 4, the friction force generated during the buffering of the impact force can be buffered, so that the impact force is further reduced, and the damage of the structure caused by excessive force is avoided.

[0031] Specifically, referring to Figure 3 The buffer part one 2 comprises a bearing plate 21 arranged on the front side of the hooking plate 11, two slot parts are formed on the front side of the bearing plate 21, two sliding rods 22 are arranged in the two slot parts respectively, four moving blocks 23 are slidingly sleeved on the outer walls of the two sliding rods 22 respectively, springs 24 are arranged between the moving blocks 23 and the side walls of the slot parts, four hinge seats 25 are arranged on the front sides of the four moving blocks 23 respectively, and four hinge seats 25 are arranged on the back sides of the mounting plate 3 respectively.

[0032] In this embodiment, when the buffer piece two 4 is forced to push the mounting plate 3, at this time, through the pushing of the hinged seat 25 and the connecting rod 26, the left and right two moving blocks 23 expand and simultaneously extrude the springs 24 on both sides, through the elastic force of the springs 24, the impact force received can be buffered, when the tug and the outside wharf or cargo ship produce lateral friction, under the action of the mounting plate 3, the moving block 23 will move like one side and extrude the spring 24 on one side, so as to buffer the lateral friction generated.

[0033] Specifically, referring to Figure 4 , the buffer piece two 4 includes four support frames 41 respectively arranged on the front of the mounting plate 3; two rotating shafts 42 respectively rotatably arranged between every two support frames 41; the two rotating shafts 42 are drivingly connected through a transmission belt 43; and an air bag ring 44 is sleeved on the outer wall of the transmission belt 43.

[0034] In this embodiment, when the tug collides with the wharf or cargo ship, the air bag ring 44 will first contact and initially buffer the impact force through its contraction ability, when the tug and the outside wharf or cargo ship produce up-down friction, the air bag ring 44 drives the transmission belt 43 and the rotating shaft 42 to rotate in turn, and the generated rotation ability can buffer the friction force generated.

[0035] Specifically, referring to Figure 4 , the support frame 41 is detachably connected between the fixed screw rod one 5 and the mounting plate 3, one end of the fixed screw rod one 5 penetrates the support frame 41 and the mounting plate 3 in turn and is threadedly connected between the mounting plate 3.

[0036] In this embodiment, when the air bag ring 44 is used for a period of time, the fixed screw rod one 5 can be reversely screwed to disassemble the support frame 41 on one side, since the side of the transmission belt 43 and the air bag ring 44 is not blocked, the two can be disassembled and replaced.

[0037] Specifically, referring to Figure 2 , the outer wall of the hooking plate 11 is provided with a fixed screw rod two 6 for reinforcing the threaded rod 12, one end of the fixed screw rod two 6 is threadedly penetrated through the hooking plate 11 and abuts against the outer wall of the threaded rod 12, and the abutting block 14 is made of rubber material.

[0038] In this embodiment, the fixed screw rod two 6 can reinforce the threaded rod 12, so as to avoid the possibility of loosening of the threaded rod 12 when the impact force received by the tug is too large, and the design that the abutting block 14 is made of rubber material not only can increase the friction force between the abutting block 14 and the ship side and improve the fixing effect, but also can better adapt to the shape of the ship side through the contraction of the abutting block 14.

[0039] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
