Anti-collision trailer for shield tunneling machine

The invention discloses an anti-collision trailer for a shield tunneling machine. The anti-collision trailer comprises a trailer frame, trailer traveling wheels, an anti-collision frame and anti-collision frame traveling wheels, wherein the trailer frame is hinged to the anti-collision frame through hinging components; the trailer traveling wheels and the anti-collision traveling wheels are arranged at the bottom ends of the trailer frame and the anti-collision frame respectively; the anti-collision frame is U-shaped, and an accommodation cavity is formed in the anti-collision frame; a segment trolley is arranged in the accommodation cavity. The anti-collision trailer for the shield tunneling machine is simple in structure; moreover, the segment trolley can also be prevented from colliding with a belt conveyor and an erector, so that the anti-collision trailer is high in safety coefficient.
