Due to the arrangement, when the ballast raking mechanism operates at a certain operation position A, the walking mechanism 200 does not need to stop for waiting, and can continue to move forwards. After the ballast scraping mechanism finishes the operation of the operation position, the operation is accelerated to move forward, and meanwhile, the next operation position is reached.
Specifically, in the present embodiment, the slide ways 610 are disposed on two sides of the frame 100 along the width direction of the rail 20, the slide ways 610 are perpendicular to the width direction of the rail 20, and the moving frame 600 is slidably connected in the slide ways 610 through a slider, a wire rail or a bearing. The moving frame 600 may further be provided with a suitable moving driving member, which may be disposed at one end of the carriage 100, for example, a hydraulic cylinder, a pneumatic cylinder, or a screw structure, and the moving driving member may extend and contract to drive the moving frame 600 to move.
