A connecting flange 16 is mounted on the rotary frame 15. The moving direction of the second lateral moving mechanism is perpendicular to the moving direction of the first lateral moving mechanism. In use, the base frame 1 of this embodiment is installed at the rear of the special vehicle. The maintenance equipment is connected to the connecting flange 16 via threaded fasteners. The first lateral moving mechanism enables the maintenance equipment to move forward and backward, the second lateral moving mechanism enables the maintenance equipment to move left and right, and the lifting mechanism enables the maintenance equipment to move up and down.
