The invention provides an automatic rope arranging device for coalmine winches. The automatic rope arranging device comprises a drum used for winding of wire ropes, a guide roller parallel to a drum shaft is arranged under the drum, a rope guide wheel moving horizontally along the guide roller and playing a role in guiding the wire ropes is arranged on the guide roller, and the rope guide wheel is connected with a piston rod of a hydraulic oil cylinder; travel switches are arranged at two ends of the drum fixedly and respectively. By telescopic motion of the hydraulic oil cylinder, the rope guide wheel drives the wire ropes to move leftwards or rightwards simultaneously, so that the wire ropes are arranged on the drum densely and sequentially circle by circle, and the purpose of automatic rope arrangement is realized. Meanwhile, rope pressing, rope skipping, rope disorder and the like are avoided, service lives of the wire ropes are prolonged, and safety production of coalmines is guaranteed.
