The invention discloses a self-propelled cable frontward moving device which comprises a monorail crane beam, a cable pulley set arranged on the monorail crane beam, a traction device and a traction steel wire rope that are arranged on the monorail crane beam, the traction device is fixedly connected with the cable pulley set through the traction steel wire rope, the traction device comprises a traction oil cylinder and fixing parts located at the two ends of the traction oil cylinder, and the fixing parts can be locked relative to the monorail crane beam or slide along the monorail crane beam. The device has the advantages that the structure is simple, the use is convenient, the cable pulley set and the traction device are installed on the monorail crane rail, the labor intensity of workers is reduced, and the working efficiency is improved. The device solves the defects that the large manpower is consumed and the efficiency is low when the cable is forwardly moved on a traditional coal mining working surface manually, the rapid forward movement can be achieved only by one person, and the device is suitable for being popularized and used for high-yield and high-efficiency coal mining working surfaces.
