Device and method for preventing shield tunneling machine battery cart sliding and colliding

The invention discloses a device and method for preventing shield tunneling machine battery cart sliding and colliding. The device comprises multiple portal frames which are vertically arranged, the portal frames are arranged in parallel at intervals at the set distance to form an integral portal structure, blocking parts are arranged between the two side walls of one or more portal frames, each blocking part comprises two oblique rods which are crosswise arranged, one end of each oblique rod is hinged to one side wall of the corresponding portal frame, and the other end of each oblique rod is connected with a lifting power source. According to the device, the losses caused by a battery cart sliding accident can be effectively reduced, the life safety of shield tunneling machine workers is effectively guaranteed, and an expensive shield tunneling machine is protected; although the device can be destroyed after the sliding accident occurs, the device is simple in structure, convenient to maintain and low in ma
