Detection system and detection method of friction elevator rope groove wear loss

Abstract

The invention provides a detection system and a detection method of friction elevator rope groove wear loss, and belongs to the detection system and the detection method of the elevator rope groove wear loss. The system comprises an upper computer, a laser displacement sensor, a collector, a direct-current power source module and a sensor support. The laser displacement sensor is installed on the sensor support, and the output end of the laser displacement sensor is connected with the collector. An encoder is installed on a roller of an elevator, the output end of the encoder is connected with an Ethernet, and the output end of the collector is connected with the input end of the upper computer through an interface of the Ethernet. The upper computer achieves real-time analysis of the on-line detection of the friction elevator rope groove wear loss and determines the wear loss conditions of different positions according the encoder. The detection system and the detection method have the advantages that the real-time quick on-line detection of the wear loss of a friction liner can be achieved, the friction liner needing to be replaced can be positioned precisely in real time, the working intensity of workers is reduced, the service life of a steel wire rope is prolonged, and the problem that real-time monitoring of the wear loss of the friction line cannot be achieved in a project is solved.

Description

technical field [0001] The invention relates to a detection system and a detection method for the wear amount of a rope groove of a hoist, in particular to a detection system and a detection method of the wear amount of a rope groove of a friction hoist. Background technique [0002] The force of the wire rope is different in each stage of the skip in the lifting process. In each operation stage of the skip, because the friction condition of the friction pad on the drum is not uniform friction in the ideal state, the length of the steel wire rope will not be exactly the same during the process of lowering or lifting the wire rope of the drum, resulting in a difference in rope length, making The unbalanced tension between the wire ropes poses a serious threat to hoisting safety and the service life of the wire ropes. [0003] Therefore, the influence of the wear condition of the friction pad of the drum on the tension of the hoisting wire rope and the influence of the length...
