Automatic deviation rectifying device for crawler-type tunnel operation trolley

An automatic deviation rectifying device of a crawler-type tunnel operation trolley comprises a frame, crawler walking mechanisms are installed on the two sides of the front end and the two sides of the rear end of the bottom of the frame, the trolley can move in a tunnel, a plurality of rows of deviation rectifying wheel mechanisms which are horizontally arranged are installed on the front side and the rear side of the frame, and the deviation rectifying wheel mechanisms can make contact with protrusions in the tunnel preferentially. The controller enables the crawler walking mechanisms at the bottom to generate rotation speed difference, so that the vehicle body generates deflection rotation, direct collision with protrusions in the tunnel is avoided, the automatic deviation rectifying function is achieved, the labor intensity of trolley driving workers is reduced to a certain degree, normal walking of the trolley in the tunnel can be effectively guaranteed, and the working efficiency is improved. And the s
