[0002] Bridge bearings are an important component of bridge structures. Their main functions include supporting the bridge superstructure, transferring loads, and accommodating beam rotation. Over time, bridge bearings may need to be replaced due to aging, damage, or performance degradation. To ensure the safety and normal use of bridges, bearing replacement is particularly important. However, traditional bearing replacement methods are often inefficient and pose safety hazards. Therefore, bridge bearing disassembly and assembly brackets have emerged.

[0003] Currently, most bridge bearing assembly and disassembly brackets do not adequately reinforce the bracket itself during use, which may cause the bracket to sway and pose certain safety hazards. Therefore, those skilled in the art have provided a bridge bearing assembly and disassembly bracket to solve the problems mentioned in the background art. Utility Model Content

[0023] Please see Figure 1-4This utility model provides a technical solution: a bridge bearing assembly / disassembly bracket, including a base plate 1, a base 8 fixedly connected to the outer surface of the base plate 1, a U-shaped seat 22 fixedly provided at the bottom end of the base 8, and fixed legs 11 fixedly provided at the four corners of the bottom end of the U-shaped seat 22. Four second electric jacks 2 are fixedly connected to the outer surface of the base plate 1, and the output ends of the second electric jacks 2 are all connected to a top plate 3. The base 8 is hollow inside, and a forward and reverse motor 23 is fixedly provided in the middle of the top of the base 8. The output end of 23 is connected to a rotating rod 24. The bottom of the rotating rod 24 is fitted with a bearing 25 fixed inside the base 8. The top outer surface of the rotating rod 24 is fixed with a secondary meshing gear 26. Four secondary meshing gears 27 are meshed on the side of the meshing gear 26. A lead screw 28 is fixedly threaded through the central shaft of the secondary meshing gear 27. A threaded plate 29 is threaded on the lead screw 28. A support rod 30 that passes through the fixed leg 11 is fixed at the bottom of the threaded plate 29. A roller is provided at the bottom of the support rod 30.

[0024] See Figure 1-4 The inner wall of the equipment slot 21 of the U-shaped seat 22 is fixedly provided with symmetrically arranged hydraulic rods 15. The output end of each hydraulic rod 15 is fixedly connected to a support platform 14. The outer surface of the support platform 14 is provided with a storage slot 13. The inner wall of the storage slot 13 is fixedly connected to a first electric jack 12. The output end of the first electric jack 12 is fixedly connected to a load-bearing plate 10. The outer surface of the top plate 3 is fixedly connected with a rubber anti-slip pad 18. The outer surface of the top surface of the rubber anti-slip pad 18 is provided with anti-slip stripes. The outer surface of the bottom plate 1 is fixedly connected with a baffle 7. A control panel 6 is fixedly connected to the top plate 3. The outer surface of the control panel 6 is equipped with operation buttons. A horizontal plate is fixedly installed on the outer wall of the baffle 7. A telescopic handle 38 is fixedly installed on the horizontal plate. The auxiliary block 17 slides in the auxiliary groove 16 as the support platform 14 moves, which improves the efficiency of the hydraulic rod 15 in moving the support platform 14. A hydraulic rod 15 is fixedly connected to the inner side wall of each equipment groove 21. The baffle 7 can provide certain protection for the equipment. Construction personnel can operate the entire equipment through the control panel 6. The telescopic handle 38 can be retracted without affecting the use of the top plate 3.

[0025] See Figure 1-4Each of the four corners of the bottom of the base plate 1 is fixedly connected to a third electric jack 5. The output end of each third electric jack 5 is fixedly connected to a stabilizing foot 9. Each equipment slot 21 has an auxiliary slot 16 on its inner side wall. Each auxiliary slot 16 has an auxiliary block 17 inside. The side of each auxiliary block 17 away from the auxiliary slot 16 is fixedly connected to the outer surface of the support platform 14. The output end of the second electric jack 2 is fixedly connected to the bottom of the top plate 3 through an auxiliary connecting plate 4. An operation light 20 is fixedly connected to the outer surface of the top plate 3. An equipment usage introduction plate 19 is fixedly connected to the outer surface of the baffle 7. The operation light 20 will stay on continuously to provide a warning when the equipment is started. The equipment usage introduction plate 19 can help construction personnel understand the applicable scope of the device and equipment. The auxiliary connecting plate 4 can improve the stability between the second electric jack 2 and the top plate 3, making the equipment more stable when supporting the bridge. The rubber anti-slip pad 18 can effectively increase the friction between the top plate 3 and the bridge, so that the rubber anti-slip pad 18 can better provide support for the bridge.

[0026] See Figure 2 The top and bottom of the lead screw 28 are fitted with bearings 31 fixed inside the base 8. Four vertical traction rods 32 are fixed inside the base 8. Four sets of limiting components are fixed on the inner wall of the base 8. Each set of limiting components includes an upper limiting plate 33 and a lower limiting plate 34. Limiting threaded holes 35 are opened on the upper limiting plate 33, the lower limiting plate 34 and the threaded plate 29. Threaded limiting rods 36 are inserted into the corresponding limiting threaded holes 35. Limiting plates 37 are fixedly provided on both the upper limit plate 33 and the lower limit plate 34. The base 8 has opening and closing doors on both sides. The threaded plate 29 moves vertically up and down on the screw 28, eventually driving the fixed leg 11 and the roller to extend out of the fixed leg 11 and slowly lift the entire device. The entire device is easy to move with the roller. During the extension of the roller, the threaded plate 29 descends vertically on the screw 28. The threaded plate 29 descends and contacts and abuts against the limiting plate 37 of the lower limit plate 34. At this time, the limiting plate 37 just abuts against the bottom end face of the threaded plate 29, indicating that the roller can no longer descend. At this time, the limiting threaded holes 35 of the threaded plate 29 and the lower limit plate 34 correspond. Then, the personnel screw the threaded limiting rod 36 into the limiting threaded hole 35 to complete the fixation of the threaded plate 29 after it descends, and finally limit and fix the extended roller.

[0027] Conversely, when the roller retracts into the fixed leg 11, the threaded plate 29 rises vertically on the lead screw 28. When the threaded plate 29 rises and contacts and abuts against the limiting piece 37 of the upper limit plate 33, it means that the roller can no longer rise. At this time, the threaded plate 29 and the limiting threaded hole 35 of the upper limit plate 33 correspond. Then, the operator screws the threaded limiting rod 36 into the limiting threaded hole 35 to finally fix the retracted roller.

[0028] In practical operation, the construction personnel first need to transport the equipment to a suitable location. The forward and reverse motors 23 drive the rotating rod 24 and the meshing gear 26 to rotate, which in turn drives the secondary meshing gear 27. The rotation of the secondary meshing gear 27 drives the lead screw 28 to rotate synchronously, thus driving the threaded plate 29 to move vertically up and down on the lead screw 28. This ultimately causes the fixed leg 11 and rollers to extend out of the fixed leg 11, slowly lifting the entire equipment. The entire device, with the rollers, facilitates movement. Personnel, using the telescopic handle 38, can easily push the entire device for subsequent effective carrying. The telescopic handle 38 is an existing component, a telescopic handle found on existing suitcases. The fixed leg 11 will then be used to lift the equipment... Once the equipment is placed stably, start the device via control panel 6. At this time, hydraulic rod 15 will apply force to support platform 14, causing support platform 14 to move within equipment slot 21. Auxiliary block 17 will slide in conjunction with support platform 14 within auxiliary slot 16. Then, first electric jack 12 will apply force to load-bearing plate 10, making load-bearing plate 10 fit tightly against the ground. Simultaneously, third electric jack 5 will apply force to stabilizing foot 9, making stabilizing foot 9 fit tightly against the ground. Finally, second electric jack 2 will provide upward support to top plate 3, making the rubber anti-slip pad 18 on top plate 3 fit tightly against the outer surface of the bridge. When the equipment is running, operation light 20 will remain constantly lit as a warning.

[0029] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
