Detection device and method used for rope disorder in process of multi-layer winding around reel

Abstract

The invention discloses a detection device and method used for rope disorder in the process of multi-layer winding around a reel, and belongs to a rope winding detection device of a winch. Contact switch supports of a detection mechanism of the device are installed between a linear bearing and a lead screw nut, and contact switches are connected to the contact switch supports. A detection device support is installed in front of the reel, bearing pedestals and a motor support are installed on the detection device support, a lead screw motor is installed on the motor support and connected with a lead screw through a lead screw coupler, the lead screw nut is installed on the lead screw, and optical shaft supports are installed on the bearing pedestals. An optical shaft is locked on the optical shaft supports through locking bolts, the linear bearing is installed on the optical shaft, an encoder is installed on an encoder support, the encoder support is installed on a reel support, the encoder is connected with the reel through a reel coupler, and the signal wire of the encoder and the signal wires of the strip-shaped contact switches are connected to the input end of a PLC. The detection device can conveniently, rapidly and accurately monitor rope running of the reel on line, it is avoided that because steel wire ropes are disorderly wound, rope damage or breakage occurs, and the service life of the steel wire ropes is prolonged.

Description

technical field [0001] The invention relates to a device and method for monitoring rope winding of a hoist, in particular to a device and method for detecting disordered ropes in multi-layer winding of a reel. technical background [0002] Under normal circumstances, the wire ropes wound on the hoist drum are arranged in disorder, and the "disorderly buckle" phenomenon of the cables squeezing each other often occurs, which causes the wear of the wire ropes, seriously shortens the service life of the wire ropes and even breaks the ropes. And cause dangerous accident; In order to solve this problem, a lot of arranging rope technologies have occurred, but these technologies can't completely solve the phenomenon of "disorderly buckling" of ropes. For example, the purely mechanical rope arrangement device has a simple structure, but due to friction, wear and deformation, misoperation and inaction often occur, which can easily lead to safety accidents; and some rope arrangement de...
