Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] The embodiment of the present invention discloses a method for detecting the fault of a steel wire rope in a multi-layered drum wire rope transmission mode, such as figure 1 shown, including the following steps:

[0042] Step 1, use laser ranging to scan the transverse tangent state of the reel in real time;

[0043]When the system is started, it is first necessary to collect the current state of the wire rope at the transvers...

Abstract

The invention discloses a drum steel wire rope fault detection method in a multi-layer drum steel wire rope transmission mode. Laser ranging is used to obtain the horizontal tangent state of the drum, and the acquired data is processed and compared with features. If there is no disordered rope feature, continue Detection, if a rope disorder fault is detected, collect the horizontal tangent data of the reel multiple times, judge the fault state again, and count the number of detections at the same time. At the same time, continue to continuously detect the state of the reel until the steel wire rope of the reel is artificially rearranged, then the alarm can be eliminated. The invention can effectively solve the fault detection problem of reel wire rope arrangement, can detect the fault type (job jumping, disordered rope, one-way coil pile) and quickly send out an alarm signal to remind the user to maintain and restore the faulty drum, greatly reducing the disorder The failure rate brought by the rope effectively prolongs the service life of the wire rope.

Description

technical field [0001] The invention relates to the technical field of transmission detection, and more particularly to a method for detecting the fault of a drum wire rope in a multi-layer drum wire rope transmission mode. Background technique [0002] In a variety of equipment that uses wire rope and drum transmission, due to long-term operation or failure of the rope guide, it may lead to the disorder of the wire rope on the surface of the drum (random rope), one-way coil stacking, slot-hopping and other failures. The single-layer arrangement of the reel is disordered (random rope), one-way coil stacking, and slot-hopping can cause the single-layer extrusion deformation and staggered winding of the steel wire rope. The disorderly interlocking arrangement squeezes the lower wire rope, resulting in serious deformation and bending of the wire rope; and when the rope is loosened (generally lowering heavy objects), due to the staggered winding caused by the wrong arrangement, ...
