The embodiment of the utility model provides an anti-collision device of a trackless rubber-tyred vehicle, and relates to the technical field of coal mine safety. The anti-collision device of the trackless rubber-tyred vehicle comprises a bottom plate, an elastic piece, a blocking piece and a magnet assembly. The bottom plate is horizontally arranged in a containing pit in the ground of a roadway. The elastic piece is fixed on the bottom plate; the blocking piece is fixedly connected with the elastic piece; the magnet assembly comprises a first electromagnet and a second electromagnet, the first electromagnet is fixedly connected with the blocking piece, and the second electromagnet is fixedly connected with the bottom plate. When the trackless rubber-tyred vehicle stalls, no attraction exists between the first electromagnet and the second electromagnet, the elastic piece drives the blocking piece through the elasticity of the elastic piece, at least part of the blocking piece can stretch out of the containin
