Description
Technical Field
[0001] This utility model relates to the field of bridge protection, and in particular to a self-floating bridge anti-collision device with a long service life. Background Technology
[0002] With the development of human society, there are more and more ships, larger and faster tonnage, and the problem of ships colliding with bridges is becoming increasingly prominent. There are many reasons for ship collisions with bridges, among which human factors rank first, equipment factors rank second, and severe weather factors rank third. It can be seen that waterway management departments can reduce the occurrence of ship collisions with bridges through standardized management, but cannot completely avoid them. Once a ship collision with a bridge occurs, the losses are heavy.
[0003] Therefore, it is necessary to set up mature anti-ship collision facilities to ensure the safety of bridges. A search revealed Chinese Patent Publication No. CN217870300U, which discloses a self-floating bridge anti-collision facility. This facility includes an anti-collision device, with the bridge body nested inside. A second solid pontoon is fixedly connected inside the anti-collision device, and a wear-resistant rubber pad is fixedly connected inside the second solid pontoon. An anti-collision buffer damper is fixedly connected to the outer side of the anti-collision device. This self-floating bridge anti-collision facility, by setting up the anti-collision device and fitting it to the outer side of the bridge body, can provide a certain degree of buffering and protection. After a collision, the external shock-absorbing and wear-resistant rubber block and the first solid pontoon will move towards the center of the bridge body. Thus, the energy generated by the ship impact is dissipated through the combined action of the anti-collision device, the anti-collision buffer damper, and the movable support, prolonging the interaction time between the ship and the bridge, greatly reducing the energy exchange between them, and significantly reducing the direct force on the bridge.
[0004] The existing technical solutions described above have the following drawbacks: In these solutions, the crash barriers are fixed together during use. When the first fixed pontoons on both sides of the crash barrier are impacted, they impact the sides of the crash barrier, causing damage to the first fixed pontoons. This prevents them from playing a role in crash protection and reduces the service life of the crash protection facility. Furthermore, when using crash protection dampers, excessive impact force can cause the first fixed pontoons to impact with the crash protection dampers, damaging both the dampers and the first fixed pontoons, which will affect the service life of the crash protection facility. Therefore, a self-floating bridge crash protection device with a long service life is proposed to solve the above problems. Utility Model Content

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 protection scope of the present utility model.
[0032] Reference Figure 1-3 This utility model provides an embodiment of a long-life self-floating bridge anti-collision device, comprising a bridge body 1, a wear-resistant rubber pad 2 on the surface of the bridge body 1, a second solid pontoon 3 on the surface of the wear-resistant rubber pad 2, anti-collision plates 4 on the top and bottom of the second solid pontoon 3, a first solid pontoon 5 on the surface of the second solid pontoon 3, a buffer shock-absorbing wear-resistant rubber block 6 fixedly connected to the surface of the first solid pontoon 5, a storage opening 7 on the inner wall of the anti-collision plate 4 for storing a push plate 9, a support rod 8 slidably connected inside the storage opening 7 for supporting a buffer plate 12, a push plate 9 fixedly connected to the surface of the support rod 8 for pushing a buffer spring 10, and a push plate 9 fixedly connected to the inner side of the push plate 9. There is a buffer spring 10, which can buffer the impact after the first solid float 5 is impacted. The surface of the support rod 8 is fitted with a shock absorber 11, which can buffer the impact between the impact plate 4 and the buffer plate 12. The inner wall of the first solid float 5 is fixedly connected to the buffer plate 12, which can prevent the first solid float 5 from impacting the impact plate 4 and thus buffer the impact. The inner wall of the buffer plate 12 is fixedly installed on the surface of the support rod 8. The outer side of the shock absorber 11 contacts the inner side of the buffer plate 12. The front and back of the impact plate 4 are fixedly connected with connecting components. The front and back of the impact plate 4 are provided with limit components. The outer side of the support rod 8 is fixedly connected with a force-bearing component. The wear-resistant rubber pad 2 is provided with a buffer component inside. The buffer spring 10 is provided with a reinforcing component inside.
[0033] Reference Figure 2-4The connecting assembly includes a connecting block 13, which can hold two anti-collision plates 4 together and limit them with a limiting box 14. The connecting block 13 is fixedly connected to the outside of the anti-collision plate 4. Limiting boxes 14 are provided on both the front and back of the anti-collision plate 4. The limiting boxes 14 can limit the connecting block 13 and prevent displacement. The limiting boxes 14 are located outside the connecting block 13. A threaded rod 15 is slidably connected to the surface of the limiting box 14. The threaded rod 15 can tighten and limit the limiting box 14 and the connecting block 13. The inner side of the threaded rod 15 passes through... After passing through the connecting block 13 and the limiting box 14 and extending to the outside of the limiting box 14, the surface of the threaded rod 15 is threaded with a nut 16. The nut 16 can further ensure the stability of the threaded rod 15 in fixing to the connecting block 13, and effectively improve the stability of the threaded rod 15 during use. The outside of the limiting box 14 is fixedly connected with a tensioning spring 17. The tensioning spring 17 can continuously pull the threaded rod 15. The inner side of the tensioning spring 17 is fixedly connected to the surface of the limiting box 14, and the tensioning spring 17 is located on the outside of the threaded rod 15.
[0034] Reference Figure 1-3 The force-bearing component includes a force-bearing plate 18, the outer side of which is fixedly installed on the inner side of the buffer plate 12. The force-bearing plate 18 can increase the contact area between the support rod 8 and the buffer plate 12, making it less likely for the support rod 8 to cause puncture damage to the buffer plate 12. The buffer component includes a buffer sleeve 19, which is located inside the wear-resistant rubber pad 2 and inside the support rod 8. The buffer sleeve 19 can buffer the inner side of the support rod 8. The reinforcement component includes a buffer frame 20, which can buffer the buffer spring 10 and enhance the buffering effect of the buffer spring 10. The buffer frame 20 is fixedly connected to the surface of the buffer spring 10.
[0035] Working Principle: After the first solid buoy 5 and the shock-absorbing and wear-resistant rubber block 6 are impacted by the ship, the buffer plate 12 is pushed, which in turn pushes the support rod 8 and the push plate 9. The push plate 9 on the surface of the support rod 8 is cushioned by the buffer spring 10, reducing the impact force. Furthermore, the anti-collision spring 11 further reduces the impact force of the buffer plate 12 after impact, preventing damage to the first solid buoy 5 after it impacts the buffer plate 12 and impacts the surface of the anti-collision plate 4. The buffer plate 12 buffers the impact between the first solid buoy 5 and the anti-collision plate 4, preventing excessive impact force from damaging the first solid buoy 5. The anti-collision spring 11 further prevents collision between the first solid buoy 5 and the anti-collision plate 4. The support rod 8 can slide and retract inside the receiving opening 7 when the first solid buoy 5 impacts the surface of the anti-collision plate 4, preventing the support rod 8 from causing puncture damage to the first solid buoy 5 during impact. This achieves the goal of preventing damage to the first solid buoy 5 during impact and improving efficiency. To extend the service life of the first solid pontoon 5 during collision avoidance, and to fix the anti-collision plates 4 together and prevent the surface of the anti-collision plates 4 from damaging the first solid pontoon 5 during collision avoidance, after the two connecting blocks 13 come into contact, the limiting box 14 is used to cover them, and then the threaded rod 15 is pulled to elastically stretch the tensioning spring 17. Then, the limiting box 14 slides on the surface of the connecting block 13, so that the threaded rod 15 can pass through the connecting block 13 and the limiting box 14 in sequence to fix the anti-collision plate 4. This ensures that the surface of the anti-collision plate 4 is smooth and will not be damaged when the first solid pontoon 5 hits the surface of the anti-collision plate 4. After the nut 16 is threaded onto the surface of the threaded rod 15, the threaded rod 15 further stabilizes and fixes the limiting box 14 to the surface of the connecting block 13 to ensure the stability of the anti-collision plate 4. This achieves the effect of conveniently fixing the anti-collision plate 4 and preventing the anti-collision plate 4 from damaging the first solid pontoon 5 during collision avoidance, thus affecting its service life.
