Abstract
The invention discloses a lifting steel wire rope stalling protection device and an application method thereof. The lifting steel wire rope stalling protection device comprises a capture mechanical arm, a mechanical arm driving unit, two vertically-arranged buffer arms and a horizontally-arranged buffer beam connected between the two buffer arms. A lifting steel wire rope vertically penetrates through the buffer beam. Movable racks which can move in the width direction of the buffer beam are arranged on the two sides in the length direction of the buffer beam oppositely. The capture mechanical arm is fixed to one of the movable racks. The buffer arms comprise hollow arm frame bodies and buffer bodies arranged in the length directions of inner cavities of the arm frame bodies. Extruding units used for transversely extruding the buffer bodies are arranged in the inner cavities, corresponding to the upper positions of the movable racks, of the arm frame bodies. Capture action on the lifting steel wire rope through the capture mechanical arm is achieved through the mechanical arm driving unit. Downward energy conducted on the lifting steel rope is captured through the capture mechanical arm and sent to the buffer beam, the buffer arms and the buffer bodies in sequence. The downward energy of the lifting steel wire rope is absorbed through the deformation of the buffer bodies so as to achieve the purpose of flexible braking of the lifting steel wire rope.
