Elevator wire rope usually has stranded steel wire stranding to form, and its safety problem is mainly disconnected strand, if there is torsion in wire rope installation, very easily causes disconnected strand after long-term operation, in addition, if wire rope has quality problems or often overload operation, also can lead to wearing and tearing disconnected strand. Once a steel wire rope is broken, the number of broken strands of the steel wire rope can be rapidly increased, and finally, the steel wire rope is broken or broken strands are stirred into other steel wire ropes, so that serious elevator accidents are caused.
Therefore, the broken strand condition of the elevator steel wire rope needs to be monitored in time so as to replace the elevator steel wire rope according to the broken strand condition of the steel wire rope. The conventional method for detecting the strand breakage of the steel wire rope of the elevator mainly comprises regular manual detection or X-ray flaw detection. Manual detection mostly adopts a visual observation mode, time consumption is long, the effect is poor, and especially for the steel wire rope of a high-rise elevator with the length of hundreds of meters, the accuracy of the steel wire rope is difficult to ensure by visual observation alone. The X-ray flaw detection has high cost and complex operation, needs professional operators and is not suitable for regular and frequent detection.
In addition, some elevators have adopted wire rope detector to detect, but one section wire rope between computer lab and the elevator car often is neglected to detect because of the possibility of accident is low, detection position is complicated, though save time and cost, nevertheless there is serious potential safety hazard in reality.
