Winding drum steel wire rope fault detection method for multi-layer winding drum steel wire rope transmission mode

Abstract

The invention discloses a winding drum steel wire rope fault detection method for a multi-layer winding drum steel wire rope transmission mode. A transverse tangent state of a winding drum is acquired by utilizing laser ranging, and the acquired data are processed and subjected to feature contrasting; detection is continued if there is no rope disorder characteristic; if a rope disorder fault is detected, transverse tangent data of the winding drum are acquired for multiple times, and the fault state is judged again; meanwhile, the number of times of detection is counted, if the fault types are the same after multiple times of continuous detection, and fault information is sent to a user control and display terminal; meanwhile, the state of the winding drum is continuously detected till the winding drum steel wire rope is manually rearranged, and then alarm can be eliminated. The winding drum steel wire rope fault detection method for the multi-layer winding drum steel wire rope transmission mode can effectively achieve the purpose of arrangement fault detection of the winding drum steel wire rope, can detect the fault types (groove jumping, rope disorder and one-way winding) and rapidly send out an alarm signal to remind a user to maintain and recover the faulted winding drum, greatly reduces the fault rate caused by rope disorder, and meanwhile effectively prolongs the service life of the steel wire rope.

Description

technical field [0001] The invention relates to the technical field of transmission detection, and more specifically relates to a drum wire rope fault detection method in a multi-layer drum wire rope transmission mode. Background technique [0002] On various equipments that use steel wire rope and drum transmission, due to long-term operation or failure of the rope guide, the wire rope may be disorderly arranged on the drum surface (chaotic rope), one-way coil stacking, job hopping and other failures. Disordered single-layer arrangement of reels (chaotic ropes), one-way coil piles, and slot-hopping can cause single-layer extrusion deformation and interlaced winding of steel wire ropes. When the ropes continue to be tightened, due to the disorder of the already wound ropes, the upper ropes will be damaged. The disordered interlocking arrangement squeezes the steel wire rope of the lower layer, causing serious deformation and bending of the steel wire rope; and when the rope ...

Problems solved by technology

At present, there is no effective detection method for this kind of mechanical mechanism failure. The only way is to manually check the wire rope arrangement and check the rope guide regularly.
