The invention discloses a rope system change device for a drill machine traveling system. The rope system change device comprises an upper locking device mounted at the bottom end of a crown block frame and lower hook locking devices mounted in multiple single-pulley traveling vehicles. Multiple rib plates perpendicular to an upper wing plate and a lower wing plate are uniformly distributed between the upper wing plate and the lower wing plate of a locking beam in the upper locking device and divide an inner cavity of the locking beam into multiple cavity bodies. A first air cylinder is mounted in each cavity body. A lock catch is mounted at the top end of the piston end of each first air cylinder. Each lower hook locking device is a connecting rod mechanism and comprises a traveling hook, a first connecting rod, a second connecting rod, a third connecting rod and a guide rod which are sequentially hinged to one another. A reset spring in the tensioned state is arranged at the top end of each guide rod. The top of each guide rod and the bottom of the piston end of a second air cylinder are adjacent and coplanar, and the multiple second air cylinders arranged side by side are mounted on the outer side of the locking beam. The rope system change device is scientific and novel in structural arrangement, the rope system change action of the traveling system can be achieved through remote automatic control, and the time and labor are saved; and the self-locking function is achieved, and the safety performance is high.
