Abstract

The invention relates to a device for monitoring the state of an elevator rope. The device comprises a vibration sensor arranged on an elevator system and used for measuring the vibration of the elevator system; a data acquisition unit used for receiving and collecting the output signals of the vibration sensor to obtain the time domain data reflecting the vibration change of the elevator system over time; and a data processing unit used for processing the time domain data to obtain the vibration frequency spectrum of the elevator system. The state of the rope is determined according to the frequency spectrum. The invention further relates to a method for monitoring the state of the elevator rope, and the method comprises the steps of setting an elevator to the predetermined state; detecting the vibration of the elevator system to obtain the time domain data reflecting the vibration change of the elevator system over time; processing the time domain data to obtain the vibration frequency spectrum of the elevator system; and determining the state of the rope according to the frequency spectrum.

Description

technical field [0001] The invention relates to an elevator rope state monitoring device. The invention also relates to a method for performing elevator rope condition monitoring by means of the elevator rope condition monitoring device. Background technique [0002] Elevator ropes are generally formed by twisting multiple strands together. During the use of the elevator, as time goes by, the elevator rope will experience time-sensitive fatigue and wear, such as rope length elongation, diameter reduction, rope surface damage, one or more strands in the rope break, etc. . If the fatigue and wear of the rope exceeds the safety threshold, the rope must be replaced to eliminate the safety hazard. [0003] Therefore, in rope-suspended elevators, conventional rope condition monitoring is required. Said rope condition monitoring is generally performed by visual inspection by elevator maintenance personnel and can be assisted by means of commercially available tools. Visual ins...
