Referring to fig. 2, the base 1 includes two parallel vertical beams, two ends of each of which are provided with a cross beam, and the wheel rail extends in a longitudinal direction on the vertical beams. A wheel rail extending in the longitudinal direction is mounted at the bottom of the motor support base 8. Pulleys are mounted to the rear ends of the first and second adjustment arms 402 and 403, respectively, and slide along the wheel rails. During the rotation of the first adjusting arm 402 by the hydraulic cylinder 3, the first adjusting arm 402 and the second adjusting arm 403 rotate around respective rotation shafts, and the pulley at the other end of the first adjusting arm 402 slides along the wheel rail on the motor support base 8, and the pulley at the other end of the second adjusting arm 403 slides along the wheel rail of the base 1.

Alternatively, the battery 5 is a direct current 24V lithium iron phosphate battery.
The motor control box 6 is electrically connected with the direct-current gear motor driver 12, the direct-current gear motor driver 12 is electrically connected with the direct-current gear motor 11, the motor control box 6 sends a command to the direct-current gear motor driver 12, and the direct-current gear motor driver 12 controls the direct-current gear motor 11 to rotate forwards, reversely, stop or rotate at a speed according to the received control command.

In this embodiment, when the hydraulic cylinder 3 is operated by the hydraulic pressurizing handle 13 or the hydraulic pressure releasing handle 14, the hydraulic cylinder 3 drives the adjusting frame 4 to rotate, the adjusting frame 4 adjusts the direct current gear motor 11 to a position aligned with the operation shaft of the handcart type switch, and then the sleeve head 9 is arranged outside the operation shaft, the direct current gear motor 11 rotates and drives the operation shaft to rotate by the sleeve connecting rod 10 and the sleeve head 9, and manual shaking is replaced by the direct current gear motor 11, so that the manual operation strength is reduced.
When the operation shaft of the handcart switch is manually operated, the operation shaft needs to stop moving in time when the transmission part in the handcart switch fails, but if the operator does not realize the existence of the failure and continues to operate, the damage of the transmission part is more serious.
The dc reduction motor driver 12 presets a stop current value. When the switch handcart is rocked in place or the linkage part in the switch cabinet fails, the direct-current gear motor 11 can not drive the operation shaft to act, and the motor starts to stop rotating at the moment. When the current value reaches a preset shutdown current value during motor stall, the direct-current gear motor driver 12 controls the direct-current gear motor 11 to stop rotating.
For example, a preset motor stall current 7A. The maximum allowable current for normal swing in and swing out of the switch cart is 5A. When the linkage part in the switch cabinet fails or the switch is in place, the motor is blocked, and when the current value reaches 7A, the direct-current gear motor driver 12 controls the direct-current gear motor 11 to stop rotating. When the transmission part fails, the operation can be stopped in time, and the expansion of the failure range is avoided.
The direct-current gear motor driver 12 is connected with a computer through a direct-current gear motor driver U port 7. The external computer can send a command to the direct-current gear motor driver 12 through the direct-current gear motor driver U port 7 so as to realize parameter setting of the direct-current gear motor 11.
