Description

Technical Field

[0001] The utility model belongs to the technical field of EMU wheel pair maintenance equipment, and more specifically relates to a jacking wheel system based on lateral movement. Background Art

[0002] The operation of lifting the wheel is an important part to ensure the safe operation of high-speed trains. It is also a necessary means for daily wheel diameter detection and bearing status monitoring of high-speed trains. The wheel lifting trolley is a necessary tool for the wheel lifting operation. The operation method of the existing wheel lifting trolley is to first push the trolley forward in the direction of the train. After reaching the wheel position, turn the trolley 90°, and then push the trolley along the vertical direction of the train until the frame extends into the narrow gap between the train wheels and the track on both sides. If the alignment is not standard, the trolley needs to be repositioned and the wheel lifting operation is completed. Because the car body is heavy, it is difficult to operate whether it is turned 90° or repositioned, and a certain amount of space is required. Because the new Hulk train includes daily maintenance in the scope of passenger maintenance, the space in the passenger maintenance track is small and there is no operating space for 90° turning and backward alignment. It can be seen that the steering and alignment problems existing in the operation process of the existing wheel lifting trolley, especially in a limited space environment, will indeed bring inconvenience to the operation.
