Technical Field

[0001] This application relates to the technical field of tunnel suspension, and in particular to a tunnel vibration-resistant additional suspension fixation device. Background Technology

[0002] Tunnel suspension typically refers to a device used to install and fix various facilities inside a tunnel. It is mainly used to suspend equipment such as overhead contact lines, lighting fixtures, communication cables, and ventilation ducts. Through the tunnel suspension system, these facilities can be reasonably arranged inside the tunnel to maintain their stable position and avoid affecting traffic flow inside the tunnel.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, pipes and other equipment on the suspension system will be affected by vibrations and sway when the train passes by. Without a shock-absorbing device, long-term vibration will exacerbate their wear and may even cause them to be damaged. Utility Model Content

[0005] This application provides a tunnel vibration-resistant additional suspension fixation device, which adopts the following technical solution: it includes a tunnel wall, a fixing plate is fixedly connected to the bottom of the tunnel wall, and a pipe is provided inside the fixing plate. The bottom of the pipe is in contact with a load-bearing plate, and a second damping spring is fixedly connected to the bottom of the load-bearing plate. A second moving block is fixedly connected to the bottom of the second damping spring, and a first damping spring is provided on the right side of the second moving block.

[0006] Optionally, a movable ring is slidably connected to the outer wall of the first fixed plate, and a second fixed plate is fixedly connected to the right side of the movable ring. A threaded hole is opened on the right side of the second fixed plate, and a threaded rod is threadedly connected to the inner wall of the threaded hole.

[0007] Optionally, a rotating shaft is fixedly connected to the left side of the threaded rod, and a fixed disk is fixedly connected to the left side of the rotating shaft. The fixed disk is rotatably connected to the threaded rod through the rotating shaft. A connecting plate is fixedly connected to the left side of the movable ring, and a fixed shell is fixedly connected to the top of the connecting plate.

[0008] Optionally, a stop block is slidably connected to the inner wall of the fixed shell, a rotating block is fixedly connected to the right side of the stop block, and a moving groove is provided on the top of the fixed shell, with the inner wall of the moving groove in contact with the outer wall of the rotating block.

[0009] Optionally, a movable frame is slidably connected to the inner wall of the fixed plate, a movable groove is provided on the top of the movable frame, the inner wall of the movable groove is slidably connected to the outer wall of the load-bearing plate, the side of the inner wall of the movable groove away from the load-bearing plate is slidably connected to the outer wall of the movable block, and a rotating plate is rotatably connected to the front of the load-bearing plate.

[0010] Optionally, a movable block is rotatably connected to the side of the rotating plate away from the load-bearing plate on its back side. A slide is provided at the bottom of the movable frame. The inner wall of the slide is in contact with the outer wall of the movable block. The right side of the movable block is fixedly connected to the left side of the damping spring.

[0011] Optionally, the right side of the damping spring is fixedly connected to the right side of the inner wall of the fixed plate. There are several damping springs, which are arranged symmetrically. The front of the moving block is rotatably connected to the rotating plate. The back of the rotating plate is rotatably connected to the front of the moving block. The bottom of the moving block is in contact with the bottom of the inner wall of the fixed plate.

[0012] In summary, this application includes the following beneficial technical effects: 1. This utility model, by incorporating components such as a load-bearing plate, a second damping spring, and a second movable block, ensures that when the pipeline is subjected to vertical vibration, the bottom of the pipeline contacts the top of the load-bearing plate, causing the load-bearing plate and the second movable block to compress the second damping spring, thus partially offsetting the vibration. Simultaneously, when the load-bearing plate and the second movable block move in opposite directions, the vibration is dispersed to the first damping springs on both sides, further offsetting the vibration. This prevents the pipeline from being affected by vibration and causing wear or even damage when a train passes by, thus protecting the pipeline.

[0013] 2. This utility model, by incorporating components such as a threaded rod, a fixed plate, and connecting plates, allows the entire device to be fitted onto the starting point of the pipeline. After the two connecting plates are lowered to contact the pipeline, the operator can then rotate the threaded rod counterclockwise to move the fixed plate towards the first fixed plate until it contacts it, thus limiting the connection plates. Simultaneously, rotating the rotating blocks on the two aligned connecting plates ensures that both stops contact the tops of the two connecting plates, thereby restricting and reinforcing them. This allows for quick assembly and also restricts and secures the pipeline. Attached Figure Description

[0017] This application discloses a tunnel vibration-resistant additional suspension fixation device. For example... Figure 1 , Figure 4 As shown, it includes a tunnel wall 1, and a fixing plate 11 is fixedly connected to the bottom of the tunnel wall 1. A pipe 12 is installed inside the fixing plate 11.

[0018] In this embodiment, the bottom of the pipe 12 is in contact with a load-bearing plate 3, a second damping spring 34 is fixedly connected to the bottom of the load-bearing plate 3, a second moving block 35 is fixedly connected to the bottom of the second damping spring 34, and a first damping spring 33 is provided on the right side of the second moving block 35.

[0019] Please see Figure 4 As shown, a movable frame 31 is slidably connected to the inner wall of the fixed plate 11. A movable groove is provided on the top of the movable frame 31. The movable groove allows the movable block 32 to move under restricted conditions, preventing it from being misaligned. The inner wall of the movable groove is slidably connected to the outer wall of the load-bearing plate 3. The side of the inner wall of the movable groove away from the load-bearing plate 3 is slidably connected to the outer wall of the movable block 35. A rotating plate 321 is rotatably connected to the front of the load-bearing plate 3.

[0020] Please see Figure 3 As shown, a connecting plate 23 is fixedly connected to the left side of the moving ring 2, and a fixed shell 231 is fixedly connected to the top of the connecting plate 23. A stop block 24 is slidably connected to the inner wall of the fixed shell 231. The two stop blocks 24 can restrict the two connecting plates 23. A rotating block 241 is fixedly connected to the right side of the stop block 24. A moving groove is opened on the top of the fixed shell 231, and the inner wall of the moving groove is in contact with the outer wall of the rotating block 241.

[0021] Please see Figure 4 As shown, the right side of damping spring 33 is fixedly connected to the right side of the inner wall of fixed plate 11. There are several damping springs 33, which are arranged symmetrically. The front of moving block 35 is rotatably connected to rotating plate 351. The back side of rotating plate 351 away from moving block 35 is rotatably connected to the front of moving block 32. The bottom of moving block 35 is in contact with the bottom of the inner wall of fixed plate 11.

[0022] Please see Figure 2 As shown, a movable ring 2 is slidably connected to the outer wall of the fixed plate 11, and a fixed plate 21 is fixedly connected to the right side of the movable ring 2. A threaded hole is opened on the right side of the fixed plate 21, and a threaded rod 211 is threadedly connected to the inner wall of the threaded hole.

[0023] Please see Figure 4 As shown, a movable block 32 is rotatably connected to the side of the rotating plate 321 away from the load-bearing plate 3. A slide is provided at the bottom of the movable frame 31. The inner wall of the slide is in contact with the outer wall of the movable block 32. The right side of the movable block 32 is fixedly connected to the left side of the damping spring 33.

[0024] Please see Figure 2 As shown, a rotating shaft 22 is fixedly connected to the left side of the threaded rod 211, and a fixed disk 221 is fixedly connected to the left side of the rotating shaft 22. The fixed disk 221 is made of rubber, which can not only increase the friction between it and the outer wall of the fixed plate 11, but also prevent the outer wall of the fixed plate 11 from being worn, thus improving the service life of the device. The fixed disk 221 is rotatably connected to the threaded rod 211 through the rotating shaft 22.

[0025] The implementation principle of the tunnel vibration-resistant additional suspension fixation device in this embodiment is as follows: The entire device is fitted onto the starting part of the pipeline. Then, the two connecting plates 23 are lowered to contact the pipeline 12. The operator can then move the fixing plate 221 towards the fixing plate 11 by turning the threaded rod 211 counterclockwise until it contacts the fixing plate 11, thus limiting the connection plate 23. Simultaneously, rotating the rotating blocks 241 on the two aligned connecting plates 23 causes both stops 24 to contact the tops of the two connecting plates 23, thereby restricting the two connecting plates 23 and providing reinforcement. This allows for quick assembly and also restricts and fixes the pipeline 12. When the pipe 12 is subjected to vertical vibration, its bottom contacts the top of the load-bearing plate 3, causing the load-bearing plate 3 and the second moving block 35 to compress the second damping spring 34, thus canceling out some of the vibration. At the same time, when the load-bearing plate 3 and the second moving block 35 move in opposite directions, they will drive the first rotating plate 321 and the second rotating plate 351 to rotate respectively. Since both are rotatably connected to the first moving block 32, they can push the two first moving blocks 32 to move in opposite directions. The movement of the first moving block 32 will transmit the force generated by the vibration to the first damping spring 33, thus canceling out the vibration and preventing the pipe 12 from being affected by vibration and causing wear or even damage when the train passes by, thus protecting the pipe.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
