Description
Technical Field
[0001] This utility model belongs to the field of monitoring equipment technology, specifically relating to a railway bridge deformation monitoring device that is easy to install. Background Technology
[0002] In railway transportation systems, railway bridges, as critical infrastructure, directly affect the smooth operation of railway transport and the safety of passengers' lives and property through their structural stability and safety. With the rapid development of the railway industry, train speeds are constantly increasing and transport density is continuously expanding. Railway bridges face more stringent load conditions and environmental challenges. To ensure the safe operation of railway bridges, precise and real-time monitoring of their deformation is necessary. Continuous monitoring of bridge deformation enables early warning and alarm systems for bridge hazards, helping to prevent train accidents caused by unsafe bridges.
[0003] Existing bridge deformation detection devices, such as the bridge construction deformation monitoring device disclosed in CN221702107U, use a base integrally formed with the detection components and are connected to the wall by bolts. However, when installing the above device, construction personnel need to carry drilling equipment to operate in high-altitude or narrow working environments, which not only consumes a lot of manpower and time, but also increases the safety risks of high-altitude operations. Summary of the Invention
[0004] This utility model is proposed to solve the problems existing in the prior art, and its purpose is to provide a railway bridge deformation monitoring device that is easy to install.
[0005] The technical solution of this utility model is: a railway bridge deformation monitoring device that is easy to install, including a deformation monitor body. An installation block is fixedly installed on the outer wall of the deformation monitor body by bolts. Sliding grooves are opened on both sides of the upper and lower outer walls of the installation block. A U-shaped connecting block is slidably connected in the sliding groove. An elastic limiting component is provided on the inner wall of the U-shaped connecting block. A fixing plate is fixedly connected to the outer wall of the U-shaped connecting block. A movable clamping plate is connected to the top of the fixing plate through a spring clamping structure. An L-shaped fixing clamping plate is fixedly connected to the bottom of the fixing plate.
[0006] Furthermore, the elastic limiting component includes a triangular limiting groove formed at the bottom of the inner wall of the slide, which limits the U-shaped connecting block along its sliding direction.
[0007] Furthermore, the elastic limiting component includes sliders fixedly connected to the upper and lower sides of the inner wall of the U-shaped connecting block. A sliding cavity is provided in the slider, and a limiting block is slidably connected in the sliding cavity. The limiting block cooperates with the triangular limiting groove to realize the locking and unlocking of the limiting position.
[0008] Furthermore, the connecting rod at the top of the limiting block passes through the outer wall of the U-shaped connecting block and is fixedly connected to a connecting plate, and a handle is fixedly connected to the top of the connecting plate.
[0009] Furthermore, a spring is fixedly connected to the top of the limiting block, and the end of the spring away from the limiting block is fixedly connected to the inner wall of the sliding cavity. The spring is also mounted on the connecting rod.
[0010] Furthermore, the spring clamping structure includes a limiting hole with a convex cross-section opened on the top of the fixed plate, and a T-shaped rod is slidably connected in the limiting hole. The top of the T-shaped rod is fixedly connected to the bottom of the movable clamping plate.
[0011] Furthermore, a second spring is fitted onto the T-shaped rod, with one end of the second spring connected to a limiting hole and the other end connected to the stepped surface of the T-shaped rod.
[0012] Furthermore, a magnet is fixedly connected to the outer wall of the fixing plate.
[0013] Furthermore, the outer wall of the deformation monitor body is provided with threaded holes, and there are four sets of threaded holes, with four in each set.
[0014] The beneficial effects of this utility model are as follows: This invention utilizes the adsorption effect of magnetic sheets on the bridge's metal structure, combined with a spring clamping structure to drive the clamping action of the moving clamping plate and the fixed clamping plate, further enhancing the fixing effect. In addition, with the sliding adjustment of the U-shaped connecting block in the groove and the quick positioning of the elastic limiting component, the installation position can be adjusted at will. The entire installation process does not require drilling equipment, eliminating the tedious drilling and bolt tightening steps, significantly reducing manpower and time consumption, and is especially suitable for high-altitude or narrow working environments.
[0015] This invention utilizes the detachable design of the elastic limiting component and the convenient adjustment characteristics of the spring clamping structure. When the monitoring point needs to be adjusted or maintenance is required, the device can be quickly disassembled and reinstalled, avoiding the problem of screw hole wear caused by repeated disassembly and assembly in traditional bolt fixing methods, and significantly improving the reusability and maintenance efficiency of the equipment.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 5 As shown, a railway bridge deformation monitoring device that is easy to install includes a deformation monitor body 1. An installation block 2 is fixedly installed on the outer wall of the deformation monitor body 1 by bolts. Slide grooves 3 are opened on both sides of the upper and lower outer walls of the installation block 2. A U-shaped connecting block 4 is slidably connected in the slide grooves 3. An elastic limiting component is provided on the inner wall of the U-shaped connecting block 4. A fixing plate 5 is fixedly connected to the outer wall of the U-shaped connecting block 4. A magnet 6 is fixedly connected to the outer wall of the fixing plate 5. A movable clamping plate 7 is connected to the top of the fixing plate 5 through a spring clamping structure. An L-shaped fixing clamping plate 8 is fixedly connected to the bottom of the fixing plate 5.
[0018] The outer wall of the deformation monitor body 1 is provided with threaded holes 9. There are four sets of threaded holes 9, with four in each set. By setting multiple sets of threaded holes 9, it is easy to adjust the fixed position of the mounting block 2 on the deformation monitor body 1 according to the actual installation requirements, thereby improving the adaptability of the device.
[0019] The elastic limiting component includes a triangular limiting groove 10 formed at the bottom of the inner wall of the slide groove 3. Slider 11 is fixedly connected to the upper and lower sides of the inner wall of the U-shaped connecting block 4. The sliding cooperation between the slider 11 and the slide groove 3 can ensure the stable movement of the U-shaped connecting block 4. A sliding cavity 12 is formed in the slider 11. A limiting block 13 is slidably connected in the sliding cavity 12. The bottom of the limiting block 13 is a triangular structure that matches the triangular limiting groove 10. A spring 14 is fixedly connected to the top of the limiting block 13.
[0020] A connecting rod 15 is fixedly connected to the top of the limiting block 13. The top of the connecting rod 15 passes through the outer wall of the U-shaped connecting block 4 and is fixedly connected to a connecting plate 16. A handle 17 is fixedly connected to the top of the connecting plate 16. By pulling the handle 17, the connecting plate 16, the connecting rod 15 and the limiting block 13 can be moved synchronously. The end of the spring 14 away from the limiting block 13 is fixedly connected to the inner wall of the sliding cavity 12. The spring 14 is sleeved on the connecting rod 15. The elastic force of the spring 14 can push the limiting block 13 into the triangular limiting groove 10 to realize the limiting and fixing of the U-shaped connecting block 4.
[0021] The spring clamping structure includes a convex-shaped limiting hole 18 on the top of the fixed plate 5. A T-shaped rod 19 is slidably connected inside the limiting hole 18. The cooperation between the T-shaped rod 19 and the limiting hole 18 can prevent the T-shaped rod 19 from disengaging from the limiting hole 18. A second spring 20 is sleeved on the outer wall of the T-shaped rod 19. The top of the T-shaped rod 19 is fixedly connected to the bottom of the movable clamping plate 7. The elastic force of the second spring 20 can push the movable clamping plate 7 to move towards the fixed clamping plate 8, thereby achieving clamping and fixation.
[0022] The bottom of the movable clamping plate 7 and the top of the fixed clamping plate 8 are fixedly connected with anti-slip pads 21. The anti-slip pads 21 are made of rubber material, which can increase the friction between the clamping plate and the bridge structure, improve the fixing stability, and at the same time prevent the clamping plate from scratching and damaging the bridge surface.
[0023] The working principle of this utility model is as follows: First, according to the installation requirements of the railway bridge, select the appropriate position of the threaded hole 9 on the deformation monitor body 1, and fix the mounting block 2 with bolts; then, slide the U-shaped connecting block 4 along the slide groove 3 to the target position. At this time, the limiting block 13 in the slider 11 automatically gets into the triangular limiting groove 10 under the elastic force of the spring 14, and completes the lateral positioning; if adjustment is required, pull the handle 17 to drive the limiting block 13 out of the groove and slide it again.
[0024] Next, the fixed clamp 8 is pressed against the edge of the bridge structure, and the moving clamp 7 is pressed down to compress the T-shaped rod 19 and the second spring 20 to form an opening. The bridge is then placed in the opening, and the moving clamp 7 is released. The second spring 20 rebounds and pushes the clamp and the anti-slip pad 21 to clamp the bridge. The magnet 6 is further attracted and fixed to ensure the stability of the device.
[0025] The entire process requires no complicated tools and can be completed manually. The elastic limit component enables rapid lateral adjustment and locking, and the spring clamping structure, together with the anti-slip pad 21, adapts to the bridge edges of different thicknesses. The magnetic piece 6 enhances the overall stability. The design of multiple sets of threaded holes 9 allows the mounting block 2 to be flexibly adjusted longitudinally to adapt to various scenarios. Through the synergistic effect of the mechanical structure and elastic elements, the device achieves efficient and reliable installation of the railway bridge deformation monitor, and facilitates subsequent maintenance or relocation.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
