Online prediction system and method for remaining service life of elevator traction steel wire rope

Abstract

The invention discloses an online prediction system and method for the remaining service life of an elevator traction steel wire rope. The system comprises a detection module, a signal conditioning module, and an analysis and evaluation module. The detection module includes an oscillator and a detecting device and is used for monitoring an elevator traction steel wire rope in running in real timeby means of eddy current detection. The signal conditioning module connected with the detection module is used for converting monitored data into a detection signal. The analysis and evaluation moduleconnected with the signal conditioning module is used for comparing the collected detection signal with information, stored in a database in advance, of different wearing degrees and service lives ofelevator traction steel wire ropes and thus predicting the service life of the detected elevator traction steel wire rope. With the eddy current detection method, whether the elevator traction steelwire rope in running has a defect is monitored in real time and the residual service life of the tested steel wire rope is predicted based on signal comparison, thereby providing effective informationfor in-time repairing and replacement of the elevator traction steel wire rope. Therefore, the online prediction system and method for the remaining service life of an elevator traction steel wire rope have the important significance in safety elevator running.

Description

technical field [0001] The invention belongs to the technical field of elevator non-destructive testing, and in particular relates to an online prediction system and method for the remaining life of elevator traction wire ropes. Background technique [0002] With the rapid development of high-rise buildings in recent years, the society's demand for elevators is increasing day by day. As one of the main components to ensure the safety of elevators, elevator traction wire ropes usually experience internal and external wear, broken wires, and fatigue after being used for a period of time. , rust and other damages, thus threatening the stability of elevator performance and the safety of users. Therefore, real-time monitoring of the traction rope and timely detection of the damage of the wire rope, so as to predict the remaining life of the wire rope, are very important for the timely replacement of the wire rope. But at present, in most cases, the detection of traction wire rop...
