Unpowered obstacle-passing pulley
The invention relates to an unpowered obstacle-passing pulley. The unpowered obstacle-passing pulley comprises a shell, pulley bodies, a clamping opening body and a clamping plate. The pulley can pass through a steel rope rapidly for a long distance and is simple in structure and convenient to use. The clamping plate formed by machining a steel plate is arranged on the pulley bodies in an interactive cooperation mode, and a buckle is installed in middle connecting holes of a pull plate, the clamping plate and a guide plate in a matched mode to limit the clamping plate, so that the pulley bodies and the steel rope are connected more firmly, and safety performance is improved. Gaps matched with a steel rope supporting plate are reserved between the upper end of the clamping plate and the side walls of the pulley bodies, so that the pulley bodies pass through the supporting plate conveniently, it is unnecessary to detach and replace the pulley bodies in the rope sliding process, operating difficulty is lowered, and potential safety hazards are avoided. A hanging arm is arranged above the shell and used for hanging a safety rope, so that damage caused by friction between the safety rope and the steel rope is avoided, and safety failures are avoided. The two pulley bodies are arranged in the shell, so that the pulley is more stable in the rope sliding process without shaking front and back.
