Single-layer steel wire rope reel with rope disorder prevention judgment device

Abstract

The invention discloses a single-layer steel wire rope reel with a rope disorder prevention judgment device. The reel comprises a roller, a steel wire rope, bearing seats, a limit switch mounting rod and a rocker arm type limit switch; the roller is of a cylindrical roller structure, the steel wire rope is tightly wound on the circumferential face of the roller, the roller is arranged between the two bearing seats, the two ends of the roller are rotationally matched with the bearing seats on the corresponding sides respectively, one bearing seat is fixedly connected with the other bearing seat through the limiting switch mounting rod, a plurality of rocker arm type limiting switches are arranged in the middle of the limiting switch mounting rod and used for detecting the position of a steel wire rope wound around the roller. According to the design, the arrangement continuity of the steel wire rope can be monitored through the continuity of signals sent by the rocker arm type limiting switches, the situation that a driver manually monitors the arrangement of the steel wire rope while operating a crane is avoided, the system safety is improved, steel wire ropes with different diameters can be adapted, and the adaptation range of the system is effectively widened.

Description

technical field [0001] The invention relates to a steel wire rope reel, in particular to a single-layer steel wire rope reel with an anti-rope judging device, and is particularly suitable for a single-layer steel wire rope reel which has the function of anti-chaotic rope, low cost and stable and reliable operation. Background technique [0002] The steel wire rope is a key part of the hoisting machinery, which bears the lifting load and drives the load to move vertically or horizontally. It may cause the steel wire rope on the drum to be loose and messy. Similarly, if the drum winding system fails (such as abnormal pulleys, etc.), it will also cause the wire rope on the drum to be messy. If the drum continues to move after the rope is messed up, according to If the rope is messed up, the service life of the wire rope will be reduced to varying degrees, and there will be safety hazards. In severe cases, the wire rope will break and cause major accidents. [0003] At present,...
