Description
Technical Field
[0001] The utility model relates to the technical field of ship anchors, in particular to a ship anchor for docking and anti-collision. Background Art
[0002] The anchor of the ship's fender is mainly used to fix and stabilize the fender. The fender is usually installed on the bottom or side of the ship to reduce the impact of water flow on the hull and reduce the wear of the hull. The design of the anchor must ensure that the fender can be firmly fixed in the predetermined position and withstand the impact of water flow and ship movement.
[0003] When the existing ship anti-collision anchor is in use, the anti-collision plate is fixed to the outer wall of the hull by the anchor, and the anti-collision plate is supported by the anchor. The impact force hits the anti-collision plate, and the anti-collision plate is supported by the anchor to reduce the impact force. Since the existing ship anchor is a fixed structure, it is difficult for the anchor to quickly absorb and consume the impact force after being subjected to the impact force, so that the residual impact force can easily cause damage to the ship and surrounding structures. Utility Model Content
[0004] The utility model aims to provide an anchor for preventing collision when docking a ship, so as to solve the problem that the anchors on the market currently have poor impact absorption effect as mentioned in the above background technology.
[0005] To achieve the above purpose, the utility model provides the following technical solutions: an anchor for ship docking and anti-collision, comprising an oil pipe, an anti-collision plate and a hull, wherein the anti-collision plate is arranged at one end of the oil pipe, and the hull is arranged at the other end of the oil pipe.
[0006] Preferably, an oil injection one-way valve extending to the outside is arranged inside one end of the oil pipe, and an air pipe extending to the outside is arranged inside the other end of the oil pipe.
[0007] Preferably, a sealing disk is welded on one end of the air pipe inside the oil pipe, a sealing plug is sleeved on the inner wall of the air pipe, and a rebound spring is provided on one side of the sealing disk inside the oil pipe.
[0008] Preferably, four groups of connecting rods are welded to one side of the anti-collision plate located outside the oil pipe, a traction spring is welded to one side of the anti-collision plate located outside the connecting rod, and one end of the traction spring is welded to one side of the hull.
[0009] Preferably, the anti-collision plate and one side of the hull located on the inner side of the four groups of traction springs are both connected with a mounting plate by bolts, and a hanging ear is welded on one side of the mounting plate.
[0010] Preferably, one end of the oil pipe and the air pipe are welded with a lifting ear, and a limiting block is arranged on the inner side of the two groups of lifting ears, and the bottom ends of the two groups of limiting blocks are welded with a connecting shaft that passes through the outer side of the bottom end of the lifting ear, and the inside of the two groups of limiting blocks are welded with a square rod, and the outer walls of the two groups of square rods are sleeved with connecting columns extending to the outside of the top end of the lifting ear, and the outer walls of the square rods located at the bottom ends of the connecting columns are sleeved with a supporting spring, the bottom ends of the two groups of connecting columns are located at the outer walls of the square rods, and square sliding grooves are provided, and the top ends of the two groups of connecting columns are provided with hexagonal grooves, and the insides of the two groups of lifting ears are provided with square limiting grooves, and the outer walls of the two groups of connecting columns are located on the inner sides of the square limiting grooves.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. When the marine anchor is hit, part of the impact force is absorbed by the traction spring and the speed of impact force transmission is slowed down. The movement of the anti-collision plate drives the mounting plate, the hanging ear, the lifting ear and the oil pipe to move. The oil pipe pushes the rebound spring to compress and deform. The hydraulic oil inside the oil pipe enters the inside of the air pipe. The hydraulic oil pushes the sealing plug to move. The sealing plug continuously pushes the high-pressure gas inside the air pipe for compression. The impact force is absorbed and dispersed by the hydraulic oil and the high-pressure gas. By setting four sets of connecting rods and traction springs, the setting of the traction spring can effectively concentrate and guide the impact force to the oil pipe, and absorb and dissipate the impact force through the hydraulic oil and the high-pressure gas inside the oil pipe and the anti-collision plate, so that the impact forces can be more effectively absorbed and dispersed, thereby reducing damage to the ship and surrounding structures.
[0013] 2. When the anchor needs to be replaced, the hexagonal slot and the connecting column are pushed down by the hexagonal wrench, the connecting column drives the square block and the square slide to descend, the connecting column pushes the supporting spring to compress and deform, the square block descends and separates from the square limit slot, so that the square block cannot limit the square limit slot, the limit block is rotated to the outside of the lifting ear through the connecting shaft, and the lifting ear is separated from the hanging ear, so that the anchor can be quickly disassembled and assembled, and the anchor is easy to inspect and maintain, thereby reducing labor intensity and reducing the physical exertion of operators.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: an anchor for ship docking and anti-collision, comprising an oil pipe 1, an anti-collision plate 2 and a hull 3, wherein the anti-collision plate 2 is arranged at one end of the oil pipe 1, and the hull 3 is arranged at the other end of the oil pipe 1.
[0023] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 It can be seen that an oil injection one-way valve 101 extending to the outside is arranged inside one end of the oil pipe 1, and an air pipe 102 extending to the outside is arranged inside the other end of the oil pipe 1. A sealing disk 103 is welded to one end of the air pipe 102 inside the oil pipe 1, and a sealing plug 104 is sleeved on the inner wall of the air pipe 102. A rebound spring 105 is arranged on one side of the sealing disk 103 inside the oil pipe 1. The oil pipe 1 is filled with hydraulic oil, and the air pipe 102 is filled with high-pressure gas. The outer wall of the sealing plug 104 is in contact with the inner wall of the air pipe 102 to form a sealing structure, and the outer wall of the sealing plug 104 is slidably connected to the inner wall of the air pipe 102, the outer wall of the sealing disk 103 is in contact with the inner wall of the oil pipe 1 to form a sealing structure, and the outer wall of the sealing disk 103 is slidably connected to the inner wall of the oil pipe 1.
[0024] During specific implementation, when the ship anchor is hit, the impact force pushes the anti-collision plate 2 to move, and the movement of the anti-collision plate 2 pushes the connecting rod 201 to move. At the same time, the anti-collision plate 2 pushes the traction spring 202 to compress and deform. The traction spring 202 absorbs part of the impact force and slows down the speed of impact force transmission. The movement of the anti-collision plate 2 drives the mounting plate 4 and the hanging ear 401 to move, and the hanging ear 401 pushes the hanging ear 5 and the oil pipe 1 to move. The oil pipe 1 slides on the outer wall of the sealing disk 103. At the same time, the oil pipe 1 pushes the rebound spring 105 to compress and deform, and the hydraulic oil inside the oil pipe 1 enters the interior of the air pipe 102. The hydraulic oil pushes the sealing plug 104 to move, and the sealing plug 104 slides on the inner wall of the air pipe 102. The sealing plug 104 continues to push the inside of the air pipe 102 The high-pressure gas is compressed, and the impact force is absorbed and dispersed by the hydraulic oil and the high-pressure gas. After the impact force is gradually dispersed, the high-pressure gas and the rebound spring 105 push the hydraulic oil and the oil pipe 1 to reset, and the oil pipe 1 pushes the lifting ear 5, the mounting plate 4, the hanging ear 401, the anti-collision plate 2, the connecting rod 201 and the traction spring 202 to reset. The compression and release of the high-pressure gas can effectively absorb and disperse the impact force on the ship. By setting four groups of connecting rods 201 and traction springs 202, the setting of the traction spring 202 can effectively concentrate and guide the impact force to the oil pipe 1, and absorb and dissipate the impact force through the hydraulic oil and high-pressure gas inside the oil pipe 1 and the anti-collision plate 2, so that these impact forces can be more effectively absorbed and dispersed, thereby reducing damage to the ship and surrounding structures.
[0025] See also Figure 1 and Figure 2 It can be seen that four groups of connecting rods 201 are welded on one side of the anti-collision plate 2 located outside the oil pipe 1, and a traction spring 202 is welded on one side of the anti-collision plate 2 located outside the connecting rod 201, and one end of the traction spring 202 is welded to one side of the hull 3.
[0026] In specific implementation, the impact force is effectively concentrated and guided to the oil pipe 1 through the four groups of traction springs 202, and the impact force is absorbed and dissipated by the hydraulic oil and high-pressure gas inside the oil pipe 1 and the anti-collision plate 2.
[0027] See also Figure 1 , Figure 2 and Figure 3 It can be seen that the anti-collision plate 2 and one side of the hull 3 are both connected to the mounting plate 4 via bolts on the inner side of the four groups of traction springs 202, and a hanging ear 401 is welded on one side of the mounting plate 4.
[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6It can be seen that one end of the oil pipe 1 and the air pipe 102 are welded with a lifting ear 5, and the inner sides of the two sets of lifting ears 5 are provided with a limiting block 501, and the bottom ends of the two sets of limiting blocks 501 are welded with a connecting shaft 502 that passes through the outer side of the bottom end of the lifting ear 5, and the insides of the two sets of limiting blocks 501 are welded with a square rod 503, and the outer walls of the two sets of square rods 503 are sleeved with a connecting column 504 extending to the outer side of the top of the lifting ear 5, and the outer wall of the square rod 503 is located at the bottom end of the connecting column 504 and is sleeved with a supporting spring 505, and the bottom ends of the two sets of connecting columns 504 are located at The outer walls of the square rods 503 are provided with square slide grooves 506, the tops of the two groups of connecting columns 504 are provided with hexagonal grooves 507, the insides of the two groups of lifting ears 5 are provided with square limit grooves 508, the outer walls of the two groups of connecting columns 504 are located on the inner sides of the square limit grooves 508 and are welded with square blocks 509, the outer walls of the square rods 503 are slidably connected to the inner walls of the square slide grooves 506, the outer walls of the connecting columns 504 are slidably connected to the inner walls of the limit blocks 501, and the outer walls of the square blocks 509 are snap-connected to the inner walls of the square limit grooves 508.
[0029] During specific implementation, when the anchor needs to be replaced, an external hexagonal wrench is inserted into the hexagonal slot 507, and the hexagonal slot 507 and the connecting column 504 are pushed down by the external hexagonal wrench. The connecting column 504 drives the square block 509 and the square slide groove 506 to descend, and the square slide groove 506 slides on the outer wall of the square rod 503. At the same time, the connecting column 504 pushes the supporting spring 505 to perform compression deformation, and the square block 509 descends and separates from the square limit groove 508, so that the square block 509 cannot limit the square limit groove 508, and the limit block 501 is rotated to the outside of the lifting ear 5 through the connecting shaft 502, and the lifting ear 5 is separated from the hanging ear 401, so that the anchor can be quickly disassembled and assembled, and the anchor can be easily inspected and maintained, thereby reducing labor intensity and reducing the physical exertion of operators.
