A fixed support 220 is fixedly arranged on the machine frame 1, a screw hole is formed in the fixed support 220, and the threaded rod 222 is in threaded connection with the screw hole. The rotating wheel 221 is rotated to drive the threaded rod 222 to rotate, and the threaded rod 222 can move up and down according to the matching relationship between the threads on the outer surface of the threaded rod 222 and the screw holes, so that the function of driving the beam 21 to move up and down is realized, and the function of driving the fork frame 20 to move up and down is finally realized. This scheme mechanism is simple, and can simplify the use degree of difficulty that the shallow was overhauld to the doffing car through manually operation, guarantees that anybody can both normally conveniently use.
In order to keep the fork frame 20 moving stably as far as possible in the ascending and descending processes, the dolly for repairing a dolly also comprises a limiting mechanism, and the limiting mechanism is used for limiting the lifting rod 201 and the driving beam 21, so that the lifting rod 201 and the driving beam 21 are ensured to move along the vertical direction all the time, and the horizontal displacement can not occur, and the function of keeping the fork frame 20 moving stably is achieved.
