The invention belongs to the technical field of auxiliary equipment for coal mining, in particular to a self-moving cable bridge. The self-moving cable bridge comprises a main cable cabin, a main longitudinal beam, a main cross beam, an auxiliary cable cabin, an auxiliary longitudinal beam, an auxiliary cross beam. A PLC, a control lead, a main roll shaft, an auxiliary roll shaft, a moving oil cylinder, a cable, retractile bridges and fixed bridges, wherein the retractile bridges and the fixed bridges are arranged horizontally in pairs. According to the self-moving cable bridge, the cable is stored at the top of a tunnel, so that the top space of the tunnel is fully utilized, the cable has adequate safety clearance with people, and the people walk and work smoothly in the lower space; thecable is stored in the cable cabin of a bridge frame, so that the cable is fully protected, the people cannot be harmed by cable leakage; the cable moves forward automatically in real time with the advance of a working surface, so that the mechanization and automation of cable movement are realized; and the cable management realizes high utilization rate of tunnel space, wide operation space, safety and reliability, simple operation and high working efficiency.
