A hoisting wire rope tension monitoring device

Abstract

The invention discloses a lifting steel wire rope tension monitoring device, which comprises a bearing connection module, wherein the bearing connection module is arranged between a lifting wedge ring and a skip bucket and comprises a reverse fork, a pin shaft, a side plate and a sensor; the reverse fork is connected with the wedge ring; the pin shaft is inserted into the reverse fork and the side plate, and the sensor is embedded into the reverse fork, and is connected with the pin shaft. After material is loaded into the skip bucket, the action force of the reverse fork and the side plate is acted on the pin shaft, and the pin shaft transfers the action force to act on the sensor, so as to enable the sensor to obtain a tension monitoring signal. The lifting steel wire rope tension monitoring device has the advantages that by arranging the bearing connection module between the lifting wedge ring and the skip bucket, after the material is loaded into the skip bucket, the action force of the reverse fork and the side plate is acted on the pin shaft, and the pin shaft transfers the action force to act on the sensor, so as to enable the sensor to obtain the tension monitoring signal; the abnormal running state of the lifting system can be visually, accurately and effectively monitored, and the occurrence of the steel wire rope breaking accident is effectively avoided.

Description

technical field [0001] The invention relates to the monitoring field of mine hoisting devices, in particular to a hoisting wire rope tension monitoring device. Background technique [0002] Mine-used single-rope hoist is one of the main equipment for transporting materials and personnel in underground mining operations. Its operating status affects the production target of coal mines to a large extent, and is more directly related to mine safety. In the actual operation process, due to the lack of mature online monitoring methods in China at present, hidden dangers of accidents such as overloading of the single-rope hoisting system, secondary coal loading, and loose ropes in the tank occur from time to time. [0003] At present, in order to prevent the occurrence of overloading, the single-rope hoisting system generally adopts the method of quantitative loading, that is, the method of first passing the quantitative bucket to measure the weight and then loading. However, due ...

AI Technical Summary

Problems solved by technology

The existing monitoring method can only effectively protect a small distance in the upper part of the wellbore due to the installation position of the limit element and the indirect signal acquisition method, and cannot protect all ranges within the entire lifting depth

[0005] To sum up, the above several fault monitoring methods are all indirect monitoring methods and cannot directly and accurately monitor the abnormal operating status of the lifting system effectively.
