The invention provides a rope winding preventing elevator which comprises a lift car, a lifting slide rail, ropes, a supporting shaft, a supporting plate, rolling wheels, sliding frames, compression springs, limiting rings, winding rope wheels, motors and a controller. The supporting plate is vertically fixed onto the rear side of the upper end of the lifting slide rail. A sliding track is fixedly arranged on the supporting plate in the central axis direction of the supporting shaft. The two sliding frames are oppositely and fixedly mounted at the two ends of the sliding track. The sliding frames are fixedly connected with the end face of the sliding track through the compression springs. A vertically-mounted rope rolling wheel is fixedly arranged on each sliding frame. Two limiting rings are fixedly arranged in the positions, opposite to a rope groove of the corresponding rolling wheel, in front of and behind each sliding frame respectively. Each winding rope wheel is fixedly arranged behind the limiting ring behind the corresponding sliding frame. A winding shaft of each winding rope wheel is fixedly connected with the corresponding motor. According to the rope winding preventing elevator, when the lift car is stopped, the sliding frames slide to tighten the loose ropes, and the ropes are limited through the limiting rings, so that the ropes are prevented from getting loose and getting out of the grooves.
