It can work in collaboration with the mobile locomotive jacking machine 200, improving the efficiency of locomotive 100 maintenance and the space utilization of the maintenance workshop, while also reducing the cost of locomotive 100 maintenance.

[0032] See Figure 1 and Figure 2 The maintenance platform used in conjunction with the mobile car-lifting machine can be set on the locomotive 100 along its width direction ( Figure 1 On both sides of the locomotive 100 (in the X direction), including the first working platform 1, the first working platform 1 is provided with a drive component and a mating groove 11, the mating groove 11 is recessed in the direction away from the locomotive 100, and the mating groove 11 is provided with a plurality of extension directions around the locomotive 100 (in the X direction). Figure 1 The movable platform 12 is rotatable in the Y direction. The output end of the drive component is connected to the movable platform 12 to drive the movable platform 12 to rotate. The movable platform 12 has a clearance position arranged at an angle to the first working platform 1 and a working position flush with the first working platform 1. In the clearance position, the mobile car-lifting machine 200 can move along the extension direction of the locomotive 100 within the mating groove 11.

[0033] The maintenance platform provided by the embodiment is used in cooperation with the mobile jacking machine. When the mobile jacking machine 200 is needed to be used to lift the locomotive 100, the driving assembly is used to drive the movable platform 12 to rotate, so that the movable platform 12 is switched to the avoiding position. At this time, the mobile jacking machine 200 can move in the cooperation groove 11 and will not touch the movable platform 12, so that the safety of the mobile jacking machine 200 during operation is ensured. When the mobile jacking machine 200 moves to the appropriate position, the movable platform 12 is driven to rotate to the working position to be flush with the first working platform 1. At this time, the maintenance personnel can stably stand on the movable platform 12 to maintain the locomotive 100, so that the safety of the locomotive 100 during maintenance is ensured. Compared with the prior art, the maintenance platform provided by the embodiment can cooperate with the mobile jacking machine 200 to work, that is, the maintenance personnel can use the mobile jacking machine 200 to maintain the locomotive 100 in the area where the first working platform 1 is arranged in the maintenance workshop. The position of the locomotive 100 in the maintenance workshop does not need to be frequently changed, the efficiency of the locomotive 100 during maintenance and the space utilization rate of the maintenance workshop are improved, and the cost of the locomotive 100 during maintenance is reduced. In addition, the movable platform 12 is provided with a plurality of movable platforms 12, so that the maintenance personnel can drive different numbers and different positions of the movable platform 12 to rotate according to the position of the mobile jacking machine 200, which significantly improves the flexibility of maintenance and is more convenient for use in the maintenance site.

[0034] Specifically, the number of the movable platform 12 is determined according to the length of the cooperation groove 11 along the extension direction of the locomotive 100 and the specification thereof. As long as the movable platform 12 can stably support the maintenance personnel in the working position, the number of the movable platform 12 can be determined.

[0035] In an optional embodiment, referring to Figure 2 and Figure 3 , the movable platform 12 includes a connecting part 121 and a supporting part 122 arranged at an included angle.

The driving assembly includes a plurality of linear driving members 13 corresponding to the connecting parts 121. The output end of the linear driving member 13 is connected with one end of the connecting part 121 away from the supporting part 122, and is used to drive the connecting part 121 to rotate to drive the supporting part 122 to rotate. In this way, the connecting part 121 can only rotate relative to the first working platform 1 and cannot move. When the linear driving member 13 drives one end of the connecting part 121 away from the supporting part 122 to move linearly, the connecting part 121 as a whole rotates to drive the supporting part 122 to rotate, so that the movable platform 12 is switched between the working position and the avoiding position.
