AI Technical Summary
Technical Problem
In a pulley or pulley block, when the force direction of the pull rope is not orthogonal to the central axis or the force is uneven, it is easy to fall off from the groove, leading to safety accidents.
Method used
An anti-rope pulley is designed. By setting a rotatable pressure wheel on the pulley bracket, the pressure wheel corresponds to the pulley one by one, and a groove larger than the diameter of the pull rope is set on its outer circumference. The pressure wheel compresses the pull rope tightly. In the groove of the pulley to prevent falling off.
Benefits of technology
It effectively prevents the drawstring from falling off the pulley and improves the safety of the pulley.

Abstract
The invention discloses a rope falling preventing pulley, and belongs to the technical field of mechanical equipment. A center shaft with the two ends erected on two parallel pulley supports is included. A plurality of rotation pulley bodies are evenly arranged on the center shaft. The pulley supports are further provided with a pressing wheel shaft parallel to the center shaft. The pressing wheelshaft is provided with a plurality of rotation pressing wheels capable of preventing pull rope disengaging, wherein the pressing wheels correspond to the pulley bodies in a one-to-one manner. The pressing wheels are arranged on one sides of the pulley bodies, a pull rope is tightly pressed in grooves of the pulley bodies, the problem that the pull rope disengages from the pulley bodies is solved,and the usage safety of the pulley is improved.
