Tower crane rope breakage protection device

The utility model relates to the technical field of tower crane rope breakage protection, and discloses a tower crane rope breakage protection device which solves the problems that when an existing tower crane is used, a rope body and a lifting hook are prone to breakage, and potential safety hazards exist. When the connecting position of the steel wire rope and the lifting hook is broken, the connecting frame moves downwards under the action of gravity, so that the lower end of the moving plate is in contact with the upper end of the limiting plate, the moving plate moves to drive the supporting rod to rotate, and the steel wire rope is hung on the supporting rod along with movement of the moving plate. The supporting rods drive the clamping seats to move towards one side, the two clamping seats move towards the center, then the limiting grooves are attached to the outer portion of the steel wire, the locking action is achieved, the connecting frame and the lifting hook are prevented from falling off, rope b
