[0035] Reference Figure 3-6The interior of the mobile base 2 is fixedly connected with a lifting assembly, which includes a multi-stage electric cylinder 14. The multi-stage electric cylinder 14 is fixedly installed on both sides of the inner wall of the mobile base 2.

The auxiliary reinforcement of the ballast brush plate 13 by the reinforcing strip 18 can improve the structural strength between the ballast brush plate 13 and the lifting block 12, and prevent the ballast brush plate 13 from falling off after long-term use.

[0037] Working principle: When in use, the user first places the mobile base 2 on the surface of the rail 1, and then starts the multi-stage electric cylinder 14. The output end of the multi-stage electric cylinder 14 drives the lifting plate 15, the lifting block 12 and the ballast brush plate 13 to move downward, and the lifting block 12 drives the positioning rod 10, the adjusting rod 9, the limit block 16 and the positioning wheel 11 to move downward. After the bottom of the limit block 16 contacts the top of the fixed plate 3, the multi-stage electric cylinder 14 is stopped, and the double-headed electric cylinder 5 is started at this time. The output end of the double-headed electric cylinder 5 drives the push plate 6 and the sliding sleeve 21 to move to the side away from the multi-stage electric cylinder 14, and the push plate 6 pushes the connecting plate 7 through the axle pin. Move to the side away from the multi-stage electric cylinder 14, the connecting plate 1 7 pushes the connecting plate 2 8 to rotate along the internal axis pin through the axis pin, and the connecting plate 2 8 pushes the adjusting rod 9 to move to the side close to the lifting block 12 when rotating along the axis pin, and the adjusting rod 9 drives the positioning rod 10 and the positioning wheel 11 to move to the side close to the rail 1. After the surface of the positioning wheel 11 contacts the surface of the rail 1, the double-headed electric cylinder 5 can be stopped. At this time, when the mobile base 2 and the contact ladder 4 are pushed to move on the surface of the rail 1, the four positioning wheels 11 rotate inside the rail 1 to position the mobile base 2, so that the mobile base 2 keeps moving stably.
