Research on Chain Tension Detection System of Scraper Conveyor in Underground Coal Mine
A scraper conveyor chain tension force detection system is constructed,which adopts strain gauges to achieve continuous detection of the tension force of the scraper chain,and communicates wirelessly,and at the same time provides stable power supply for the tension force detection and communication equipment through the piezoelectric captive energy device to solve the problems faced by the traditional battery power supply,such as the short use of time and the lack of strong adaptability.The overall structure of the chain tension force detection system,the strain gauge arrangement and the structure of the piezoelectric capture device are analysed in detail.Taking 31301 comprehensive mining face SGZ1000/1710 scraper conveyor as an example,the arrangement of the tension force detection system and the application effect are discussed,and the tension force detection system can realise real-time detection of the tension force of the scraper chain after on-site application,the detection structure is similar to the results of the stress gauges,and it can satisfy the needs of efficient detection of the tension force of the scraper chain.
