An impact absorbing device for a ship side plate

Abstract

This utility model discloses an impact-resistant and shock-absorbing device for ship side plates, relating to the field of ship side plate technology. The utility model includes a ship side plate, with an impact-resistant component and a buffer component disposed in front of the side plate. The impact-resistant component is positioned in front of the buffer component and includes an impact-resistant plate, with a reinforcing plate disposed behind the impact-resistant plate. Specifically, when a ship docks and a collision occurs, the impact force first acts on the reinforcing plate, causing it to push a movable rod. The movable rod then compresses a piston, which slides within a sealed cylinder, compressing the internal gas and forming a first-stage buffer. Simultaneously, the inner cylinder slides within the outer cylinder, pushing a moving plate, which further compresses a spring, providing a second-stage buffer. This dual-buffering design significantly absorbs collision energy, reduces direct impact on the ship's side plate, greatly reduces damage to the side plate, and increases its service life.

Description

Technical Field

[0001] This utility model belongs to the field of ship side plate technology, and in particular relates to an impact-resistant and shock-absorbing device for ship side plates. Background Technology

[0002] The side plates of a ship refer to the outer plates above the bilge plates. The outer plates on the sides that connect to the deck side plates are called the bilge plates. When a ship is docked at a pier, the side plates of the ship will often collide with the edge of the pier.

[0003] Existing ship side panels are usually protected by suspending multiple tires. While this provides some protection, the tires can be pushed and shifted after a collision. Furthermore, tire protection alone is insufficient to provide adequate shock absorption and impact resistance. Prolonged collisions can still damage the side panels, thus affecting the safety of the ship. In addition, the use of tires makes them prone to damage and requires frequent replacement. Therefore, we propose an impact-resistant and shock-absorbing device for ship side panels. Utility Model Content

[0004] The purpose of this invention is to provide an impact-resistant and shock-absorbing device for ship side panels. By setting up a buffer assembly, specifically, when a ship docks and a collision occurs, the impact force first acts on the reinforcing plate, causing it to push the movable rod. The movable rod then squeezes the piston, which slides inside the sealed cylinder, compressing the internal gas to form the first buffer. At the same time, the inner cylinder slides inside the outer cylinder, pushing the moving plate to move. The latter further compresses the spring, providing a second buffer. This dual buffer design greatly absorbs the collision energy, reduces the direct impact on the ship's side panels, significantly reduces damage to the side panels, and improves service life. It solves the problem that existing ship side panels are usually protected by suspending multiple tires. Although this can provide some protection, the tires will be pushed and shifted after a collision, and the protection of tires alone is not enough to achieve better shock absorption and impact resistance. Long-term collisions will still cause damage to the side panels.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Threaded shafts are provided on the left and right sides of the two positioning blocks. The fronts of the four threaded shafts are fixedly connected to the back of the reinforcing plate, and nuts are threadedly connected to the outer sides of the four threaded shafts.

The pull rod penetrates the ship's side plate and extends to the outside, and is slidably connected to the ship's side plate. A spring is sleeved on the outside of the pull rod.

[0009] Furthermore, a mounting plate is fixedly connected to the front of the movable rod, the front of the mounting plate contacts the back of the reinforcing plate, a positioning groove is provided in the center of the mounting plate, two insertion holes are provided inside the mounting plate, the threaded shaft is inserted into the mounting plate through the insertion holes, the positioning block is inserted into the mounting plate through the positioning groove, the back of the sealing cylinder is fixedly connected to the front of the ship's side plate, and the outer side of the piston contacts the inner wall of the sealing cylinder.

[0010] Furthermore, each of the two solenoid valves is fixedly connected to a gas supply pipe on the side away from each other, and a gas pipe is fixedly connected to the left and right sides of the solenoid valves.

[0014] 1. This utility model, by setting up a buffer component, specifically, when a ship docks at the pier and a collision occurs, the impact force first acts on the reinforcing plate, causing it to push the movable rod. The movable rod then squeezes the piston, which slides inside the sealed cylinder, compressing the internal gas to form the first buffer.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figure 1-6 As shown, this utility model is an impact-resistant and shock-absorbing device for a ship side plate, including a ship side plate 1, an impact-resistant component 11 and a buffer component 12 are arranged in front of the ship side plate 1, and the impact-resistant component 11 is arranged in front of the buffer component 12.

[0028] The impact-resistant component 11 includes an impact-resistant plate 111, a reinforcing plate 113 behind the impact-resistant plate 111, a rubber pad 112 fixedly connected to the front of the impact-resistant plate 111, and several reinforcing strips 114 fixedly connected to the back of the impact-resistant plate 111. The backs of the reinforcing strips 114 are all fixedly connected to the front of the reinforcing plate 113. Two positioning blocks 31 are fixedly connected to the back of the reinforcing plate 113. Threaded shafts 32 are provided on the left and right sides of the two positioning blocks 31. The fronts of the four threaded shafts 32 are all fixedly connected to the back of the reinforcing plate 113, and nuts 33 are threadedly connected to the outer sides of the four threaded shafts 32. The reinforcing plate 113 is inserted into the positioning grooves 251 on the mounting plate 125 through the positioning blocks 31 to achieve precise positioning. The shaft 32 passes through the insertion hole 252 and is installed by tightening with the nut 33; the buffer assembly 12 includes four sealing cylinders 121, which are arranged in pairs. The four sealing cylinders 121 are located at the four corners of the front of the ship's side plate 1. A movable rod 122 is slidably connected inside the sealing cylinder 121. A piston 123 is fixedly connected to the back of the movable rod 122 and is located inside the sealing cylinder 121. Two solenoid valves 124 are fixedly connected to the front of the ship's side plate 1. Two inner cylinders 13 are fixedly connected to the back of the reinforcing plate 113. An outer cylinder 131 is slidably connected to the outside of the inner cylinder 13. A pull rod 133 is installed inside the outer cylinder 131. A movable plate 132 is fixedly connected to the front of the pull rod 133. 2. A tie rod 133 is installed inside the inner cylinder 13, passing through the ship's side plate 1 and extending to the outside. The tie rod 133 is slidably connected to the ship's side plate 1. A spring 135 is sleeved on the outside of the tie rod 133. By setting up a buffer assembly 12, specifically, when the ship docks and a collision occurs, the impact force first acts on the reinforcing plate 113, causing it to push the movable rod 122. The movable rod 122 then squeezes the piston 123, which slides inside the sealing cylinder 121, compressing the internal gas and forming the first buffer. At the same time, the inner cylinder 13 slides inside the outer cylinder 131, pushing the moving plate 132 to move. The latter further compresses the spring 135, providing a second buffer. This double buffer design greatly absorbs the collision energy and reduces the impact on the ship. The direct impact on the side plate significantly reduces damage to the side plate and improves its service life. The front of the movable rod 122 is fixedly connected to the mounting plate 125. The front of the mounting plate 125 contacts the back of the reinforcing plate 113. A positioning groove 251 is opened in the center of the mounting plate 125. Two insertion holes 252 are opened inside the mounting plate 125. The threaded shaft 32 is inserted into the mounting plate 125 through the insertion holes 252. The positioning block 31 is inserted into the mounting plate 125 through the positioning groove 251. The back of the sealing cylinder 121 is fixedly connected to the front of the ship's side plate 1. The outer side of the piston 123 contacts the inner wall of the sealing cylinder 121. The piston 123 can improve the sealing effect, thereby better compressing the air in the sealing cylinder 121 and playing a good buffering role.Two solenoid valves 124 are each fixedly connected to an air supply pipe 241 on the side furthest from each other. Air pipes 242 are fixedly connected to the left and right sides of each solenoid valve 124. The side of the air pipe 242 closest to the sealing cylinder 121 is fixedly connected to the surface of the sealing cylinder 121. The air pipes 242 and the sealing cylinder 121 are interconnected. The air supply pipes 241 are connected to an air compressor. Gas is conveniently supplied to the sealing cylinder 121 by controlling the switch via the solenoid valves 124, ensuring the system is always ready. A connecting frame 134 is provided behind the ship's side plate 1. The inner side of the connecting frame 134 is fixedly connected to the outer surface of the tie rod 133. A threaded rod 341 is threadedly connected to the center of the connecting frame 134. The front of the threaded rod 341 contacts the back of the ship's side plate 1. A handle 342 is fixedly connected to the back of rod 341. By setting a connecting bracket 134, specifically when enhanced impact resistance is needed, the threaded rod 341 can be rotated clockwise to contact the back of the ship's side plate 1. Continuous rotation will cause the connecting bracket 134 to drive the pull rod 133 backward, further compressing the spring 135, thus adjusting according to different cushioning requirements. The outer side of the moving plate 132 contacts the inner wall of the inner cylinder 13. The front of the spring 135 is fixedly connected to the back of the moving plate 132, and the back of the spring 135 is fixedly connected to the front of the ship's side plate 1. The moving plate 132 can independently compress the spring 135, adjusting its compression state, and the inner cylinder 13 can smoothly pass through the moving plate 132 to compress the spring 135.

[0029] One specific application of this embodiment is:

[0030] The reinforcing plate 113 is precisely positioned by inserting the positioning block 31 into the positioning groove 251 on the mounting plate 125. The threaded shaft 32 passes through the insertion hole 252 and is tightened by the nut 33, ensuring that the reinforcing plate 113 is firmly fixed on the mounting plate 125. Multiple reinforcing strips 114 set between the impact-resistant plate 111 and the reinforcing plate 113 not only enhance the strength of the overall structure but also effectively prevent denting and deformation when impacted. The rubber pad 112 is located between the impact-resistant plate 111 and the reinforcing plate 113, playing a buffering and protective role and reducing scratches or damage caused by collisions. When the ship docks and a collision occurs, the impact force first acts on the reinforcing plate 113, causing it to push the movable rod 122. The movable rod 122 then squeezes the piston 123, which slides inside the sealing cylinder 121, compressing the internal gas and forming the first buffer. At the same time, the inner cylinder 13 is located between the outer cylinder 121 and the inner cylinder 122. The sliding mechanism 113 pushes the moving plate 132 to move, which further compresses the spring 135, providing a second buffer. This double buffer design greatly absorbs the collision energy and reduces the direct impact on the ship's side plate. After the collision, the gas in the sealing cylinder 121 is slowly released through the solenoid valve 124, generating a certain suction force, which causes the moving rod 122 to drive the reinforcing plate 113 to slowly reset, avoiding excessive rebound and secondary damage. If it is necessary to enhance the impact resistance, the threaded rod 341 can be rotated clockwise to make it contact the back of the ship's side plate 1. Continuous rotation will cause the connecting frame 134 to drive the pull rod 133 to move backward, further compressing the spring 135, thereby adjusting according to different buffering requirements. The gas supply pipe 241 is connected to the air compressor equipment, and the switch is controlled by the solenoid valve 124 to conveniently supply gas into the sealing cylinder 121, ensuring that the system is always ready.
