Description

Technical Field

[0001] This utility model relates to the technical field of railway maintenance platforms, specifically a lifting platform for railway maintenance. Background Technology

[0002] Currently, when overhauling railway passenger cars and power-centralized EMUs, it is necessary to inspect and replace the auxiliary components on the top of the car body. Operators usually need to use commercially available lifting equipment to overhaul railway passenger cars.

[0003] Traditionally, scaffolding is used to erect dedicated maintenance platforms, such as the mobile railway passenger car body integrated maintenance platform described in patent CN202220747768.5. This platform includes a mobile base, lifting supports, and a maintenance platform. A lifting platform is located on the upper surface of the maintenance platform. The lifting platform includes a support platform and a first lifting unit. The support platform is connected to the maintenance platform via the first lifting unit, and the support platform is also slidably connected to the top of the first lifting unit. By combining the mobile base, lifting supports, and maintenance platform, maintenance can be moved to a suitable position and height as needed, making maintenance work more convenient and efficient. Furthermore, the independent lifting platform on the maintenance platform allows workers to flexibly assemble components when disassembling or replacing large parts, resulting in a more comfortable working environment.

[0004] Although the aforementioned patent allows for easy movement and is equipped with a hydraulic lifting mechanism that enables a wide range of height adjustments to adapt to different working heights, the small size of the top working platform significantly reduces the effective working range. Although it also has a telescopic structure for the top working platform, it lacks a support device. When workers stand on one side of the telescopic platform, the shift in the center of gravity can cause the platform to tilt, potentially leading to a collapse in severe cases. Utility Model Content

Under the action of external force, the telescopic platform 3 slides on the outside of the guide rail 205 via the slider 303 and the limit block 304 on the U-shaped frame 203, pulling out the support platform 302. The support platform 302 moves in the moving groove 204. Workers can perform maintenance and inspection on the support platform 302 or the lifting platform 2, and perform high-altitude operations. Example 2:

[0027] Compared to Embodiment 1, an adjustment and movement device 8 is added. The second telescopic rod 401 drives the force plate 403 to move through the fixed block 405, thereby driving the telescopic platform 3 to move through the guide rod 402, and driving the caster wheel 801 to move. The connecting column 802 of the caster wheel 801 can move up and down in the moving hole 9, and the spring 804 adjusts it. When encountering uneven ground, it can automatically adjust. When the telescopic platform 3 is unfolded, the workers can inspect and maintain it on the support platform 302.
