The invention discloses a wire rope anti-jumping device. The wire rope anti-jumping device comprises a pulley shaft, a first support, a second support, a bearing, a bearing pedestal and a first pulley, wherein the first support and the second support are installed at the two ends of the pulley shaft respectively; the bearing is installed between the two supports; the bearing pedestal is installed on the bearing; the first pulley is installed on the bearing pedestal; the first pulley is provided with rope groove used for containing a wire rope; the wire rope is installed inside the rope groove; the upper portions of the first support and the second support are connected through a connection rod; clamping grooves are formed in the two ends of the pulley shaft; baffles buckled in the clamping grooves are arranged on the outer sides of the first support and the second support; a second pulley is installed in the position, above the first pulley, of the connection rod. In the use process, the wire rope and the second pulley form rolling friction, so that abrasion to the wire rope is relieved, and the service life of the wire rope is prolonged.
