[0002] In the field of bridge bearing maintenance, maintenance platforms are often used for the inspection and maintenance of bridge bearings.
[0003] In practice, traditional maintenance platforms often encounter the following situation: when the height needs to be adjusted to meet operational requirements, adding an extra support frame will cause the platform height to exceed the required level; conversely, without the support frame, the platform height will be below the appropriate working height. This inability to achieve the correct height forces workers to resort to temporary or inappropriate methods to adjust the height. In the complex bridge working environment, this can hinder the progress of maintenance work, reduce efficiency, and increase safety risks due to frequent attempts at unstable height adjustments. Ultimately, this poses a potential threat to the personal safety of workers and the integrity of the bridge structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This utility model, through the setting of an adjusting rod and a locking block, allows users to adjust the support height of the device according to the actual structure and height requirements of the bridge. When facing bridge support maintenance scenarios at different heights, the user can rotate the rotating rod, causing the rotating block on the control component to rotate, and then pull the locking block through the pull rod, causing the locking block to slide along the mounting groove, compressing the locking spring, and thus disengaging the locking block from the slot on the adjusting rod. After this, the user can move the adjusting rod up or down according to the actual required height; once the height is determined, the rotating rod is released, the locking spring rebounds and pushes the locking block back to reset, re-engaging it into the slot, thus fixing the position of the adjusting rod and improving the flexibility of the device in height adjustment. After completing the height adjustment of the adjusting rod, the user can rotate the fastening bolt on the fixed base to drive the fixed block to clamp the adjusting rod, further stabilizing the position of the adjusting rod. This effectively prevents the adjusting rod from shifting or shaking during use, solving the problem that traditional maintenance platforms are difficult to directly adjust to the construction height.
[0018] 2. When using this device, the user can drive the scissor lift assembly to extend or retract via a cylinder, adjusting the height of the support platform. The structure, where the bottom of the scissor lift assembly is movably connected to the first mounting frame of the lifting seat via a first rotating shaft, and the top is movably connected to the second mounting frame of the support platform via a second rotating shaft, allows the device to stably raise and lower the support platform at different heights. This process provides vertical transportation assurance for users when transporting construction personnel from the bridge deck to the work platform for bridge support maintenance, improving the device's safety and practicality in personnel transport.

[0037] Please refer to, for example Figure 1 and Figure 2 As shown, a connecting frame 14 is installed on the top of the fixing frame 3. One side of the connecting frame 14 is connected to one side of the bridge by reinforcing bolts. Four sets of third flanges are welded to the bottom of the connecting frame 14, and four sets of fourth flanges are welded to the top of the fixing frame 3. The third flanges are connected to the fourth flanges.
[0038] By setting the connecting bracket 14, the fixing bracket 3 can be connected to the bridge, allowing the user to fix the device on the bridge, thus improving the overall installation stability of the device; the user can fix the connecting bracket 14 and the fixing bracket 3 by connecting the third flange and the fourth flange.
[0039] The top of the lifting platform 2 is provided with two sets of first mounting brackets, and the top of the lifting platform 2 is provided with two sets of scissor arm assemblies 16. The bottom of the scissor arm assembly 16 is movably connected to the two sets of first mounting brackets through two sets of first rotating shafts. A cylinder 17 is installed between the two sets of first rotating shafts. The cylinder 17 is powered by an external circuit. By extending and retracting the cylinder 17, the scissor arm assembly 16 is driven to expand or contract, so that the device can smoothly adjust the height of the bearing platform 18 and improve the lifting power effect of the device. If the number of fixed brackets 3 increases, the number of scissor arm assemblies 16 also increases accordingly.
[0040] The top of the scissor arm assembly 16 is equipped with a support platform 18, and the sides of the support platform 18 are equipped with guardrails 19. The bottom of the support platform 18 is provided with two sets of second mounting frames, and the bottom of the second mounting frames is movably connected to the scissor arm assembly 16 through two sets of second rotating shafts.
[0041] The support platform 18 can carry construction workers, allowing users to transport them from the bridge deck to the construction frame 1.

[0042] The specific usage and function of this embodiment are as follows:
[0043] When using this modular bridge bearing maintenance platform, the first step is to assemble the components according to the bridge structure requirements. Align the fourth flange at the top of the fixed frame 3 with the third flange at the bottom of the connecting frame 14, and secure them with bolts. If it is necessary to extend the support height, increase the number of fixed frames 3 by bolting the first flange to the fourth flange to improve the adaptability of the device. Adjust the lifting seat 2 to a suitable height according to the position of the bridge bearing, and then use reinforcing bolts to connect one side of the connecting frame 14 to the bridge to ensure that the entire device is fixed to the bridge.
[0044] When adjusting the support height of the device, insert the rotating rod 12 into the rotating hole at the top of the control component 7. Rotating the control component 7 causes the rotating block to rotate, and the pull rod 8 pulls the first connecting seat, causing the locking block 6 to slide along the mounting groove and compress the locking spring 13. The locking block 6 disengages from the slot of the adjusting rod 5. At this time, the adjusting rod 5 can be moved up and down. After the height is appropriate, release the rotating rod 12. The locking spring 13 rebounds and pushes the locking block 6 back to reset, re-engaging it into the slot to fix the adjusting rod 5. Then, rotate the fastening bolt on the fixing seat 9 to drive the fixing block 10 to clamp the adjusting rod 5, further enhancing stability. The locking brackets 15 at the bottom of the four sets of adjusting rods 5 can prevent them from shaking.
[0045] When personnel need to be transported to workbench 1, power is supplied to cylinder 17 via an external circuit. Cylinder 17 extends or retracts, driving the scissor arm assembly 16 to expand or contract. The bottom of the scissor arm assembly 16 is movably connected to the first mounting frame of the lifting seat 2 via a first pivot, and the top is connected to the second mounting frame of the carrying platform 18 via a second pivot. Under the action of cylinder 17, the carrying platform 18 smoothly rises and falls, transporting personnel from the bridge deck to workbench 1. The guardrails 19 around the carrying platform 18 prevent personnel from falling, ensuring safety during high-altitude operations.
[0046] During use, the dust cover 11 on the mounting slot prevents dust and debris from entering, protecting components such as the locking block 6 and control unit 7. After operation, the adjustment components can be reversed, and the device can be disassembled or stored for convenient subsequent use.
