The second lifting mechanism is provided to drive the storage box 38 to move up and down, thereby lifting and lowering parts to facilitate their access to the maintenance location of the railway vehicle.

[0028] Example 3, based on Example 2, a platform for railway vehicle maintenance operation, such as Figure 1 、 Figure 2 and Figure 4 As shown, the first and second lifting mechanisms have the same structure; both include hydraulic telescopic rods. The first lifting mechanism's hydraulic telescopic rod has one end connected to the base 1 and the other end connected to the standing platform 2; the second lifting mechanism's hydraulic telescopic rod has one end connected to the base 1 and the other end connected to the placement box 38. The first lifting mechanism includes a set of hydraulic telescopic rods, which are used to adjust the height of the standing platform 2; the second lifting mechanism also includes a set of hydraulic telescopic rods, which are used to adjust the height of the placement box 38, with one end connected to the base 1 and the other end connected to the placement box 38.

[0029] Among them, preferably, the standing platform 2 and the placement box 38 are both rectangular, and a group of hydraulic telescopic rods has four hydraulic telescopic rods, which are respectively located at the four corners of the rectangular platform. The four hydraulic telescopic rods are symmetrically arranged and the standing platform 2 is raised and lowered synchronously. At the same time, another group of four hydraulic telescopic rods are respectively located at the four corners of the placement box 38, and the four hydraulic telescopic rods are symmetrically arranged and the placement box 38 is raised and lowered synchronously.

[0030] Example 4, based on Example 2, a platform for railway vehicle maintenance operation, such as Figure 1 、 Figure 2 and Figure 4 As shown, the first lifting mechanism is a jacking mechanism, and the second lifting mechanism is a stretching mechanism. That is, the standing platform 2 is lifted by the first lifting mechanism to transport the workers, while the placement box 38 is stretched by the second lifting mechanism to move and transport the parts. This embodiment uses two different transportation methods to transport workers and parts respectively, achieving diverse transportation methods.

[0031] Example 5, based on Example 4, a platform for railway vehicle maintenance operation, such as Figure 1 、 Figure 2 and Figure 4 As shown, the lifting mechanism includes a hydraulic telescopic rod, one end of which is connected to the base 1 and the other end is connected to the standing platform 2. The hydraulic telescopic rod is connected to the base 1 at one end and to the standing platform 2 at the other end.

[0032] Example 6, based on Example 5, a railway vehicle maintenance operation platform, such as Figure 1 、 Figure 2 and Figure 3 As shown, the stretching mechanism includes a support bar 35, which is fixedly connected to the outer surface of the base 1. A rotating wheel 33 is rotatably connected to the support bar 35, and the rotating shaft of the rotating wheel 33 is connected to the driving motor 31. A guide groove 37 is provided on the side of the support bar 35 away from the base 1. A slider is slidably connected in the guide groove 37, and the slider is fixedly connected to the placement box 38. A pull rope 34 is passed through the guide groove 37, and one end of the pull rope 34 is connected to the slider and the other end is fixedly connected to the rotating wheel 33. When the driving motor 31 is started, the driving motor 31 drives the rotating wheel 33 to rotate, and the rotating wheel 33 rotates and drives the pull rope 34. The pull rope 34 is stored, and the pull rope 32 pulls the placement box 38. The placement box 38 is guided by the guide groove 37. When the placement box 38 slides to a specified position, the driving motor 31 is braked. The provision of the driving motor 31 facilitates the transportation of parts that need to be replaced, thereby improving the efficiency of workers in replacing parts.

[0033] Example 7, based on Example 6, a platform for railway vehicle maintenance operation, such as Figure 1 、 Figure 2 and Figure 3As shown, the support bar 35 is rotatably connected to a guide wheel 32, and the pull rope 34 is rolled on the guide wheel 32.

The limit block 62 is provided with a through hole, which is adapted to the guide rod 61. The two ends of the limit block 62 are respectively hinged to the bottom of the standing platform 2. In the process of the standing platform 2 being raised and lowered by the hydraulic telescopic rod, the limit block 62 always slides up and down along the guide rod 61. When the standing platform 2 is lifted to the highest point by the hydraulic telescopic rod, the limit block 62 is still on the guide rod 61. When the standing platform 2 is lowered to the lowest point by the hydraulic telescopic rod, the top of the guide rod 61 conflicts with the bottom of the standing platform 2.

[0037] Example 10, based on Example 9, a platform for railway vehicle maintenance operation, such as Figure 4As shown, the bottom of the base 1 is provided with a moving wheel 5. The setting of the moving wheel 5 is to facilitate the movement of the entire maintenance operation platform. It should be noted that the moving wheel 5 is equipped with a brake. When the entire maintenance operation platform needs to be moved to the position to be inspected, the brake can be turned off, and the moving wheel 5 can be rotated, and then the entire maintenance operation platform can be manually pushed to the position to be inspected; after moving to the position to be inspected, the brake is activated, and the moving wheel 5 cannot be rotated. At this time, the maintenance worker can stand on the standing platform 2 to ensure the safety of the entire maintenance work, maximize the safety during construction, and avoid accidents. The moving wheel 5 with a brake adopts the structure of the existing technology, as long as it can control whether the moving wheel 5 can rotate.

[0038] When implementing Example 10, the entire maintenance operation platform is manually pushed to the position to be inspected. After moving to the position to be inspected, the brake is activated, and the moving wheel 5 cannot rotate. Only then can the maintenance worker stand on the standing platform 2, and then the hydraulic telescopic rod is activated to lift the standing platform 2 to the position to be inspected on the railway vehicle. When parts need to be replaced, the drive motor 31 is activated, and the drive motor 31 drives the rotating wheel 33 to rotate. The rotating wheel 33 rotates and drives the pull rope 34. The pull rope 34 is stored, and the pull rope 32 pulls the placement box 38. The placement box 38 is guided by the guide groove 37. When the placement box 38 slides to the designated position, the replacement part can be quickly transported. After the inspection is completed, the hydraulic telescopic rod is closed, and the standing platform 2 can be lowered to facilitate the worker to descend to the ground. After the worker gets off the standing platform 2, the brake can be closed, and the moving wheel 5 can rotate. The worker then pushes the entire maintenance operation platform to the next position to be inspected for inspection.
