Embedded type scraping plate corner detecting device and detecting method of scraping plate conveyor

Abstract

The invention discloses an embedded type scraping plate corner detecting device and detecting method of a scraping plate conveyor. The detecting device comprises two telescopic detecting devices, two signal detecting units and a remote processing unit; the telescopic detecting devices and the two signal detecting units are arranged on the two ends of a scraping plate correspondingly, the signal detecting units detect movement displacement of the telescopic detecting devices in real time and send out signals through a wireless transmitting module, the wireless transmitting module and a wireless receiving module are used for data transmission, a signal display processing module is used for calculating the corner value of a scraping plate in real time, meanwhile, the corner value is output and displayed, the real-time measured corner value is compared with the set safety threshold value, and when the value exceeds the safety threshold value, alarm is given out, and prompt is carried out. The device is simple and reliable in structure, low in cost, small in space size, high in adaptation, good in use effect, small in calculation amount in the measuring method, good in real-time performance, high in accuracy and wide in practicability.

Description

technical field [0001] The invention relates to the field of scraper conveyors, in particular to a scraper conveyor built-in scraper rotation angle detection device and detection method. Background technique [0002] As the key equipment for mechanized coal mining in the fully mechanized mining face, the scraper conveyor undertakes the important tasks of transporting coal, providing the running track for the shearer, and providing the fulcrum for the hydraulic support. The working principle of the scraper conveyor determines that it needs to bear the effects of tension and compression, local bending, time-varying loads and impacts during operation. The harsh working environment makes its key components severely corroded, and the life of key components is short and failures occur. The probability is high, which reduces the operating rate of fully mechanized mining equipment and seriously restricts the production efficiency of large coal mines in my country. [0003] In order ...

AI Technical Summary

Problems solved by technology

In-depth analysis found that the scraper is always perpendicular to the side of the middle groove under ideal operating conditions. The angle of inclination and the angle of the scraper can be used to judge whether the scraper conveyor is running normally, but there is still a lack of feasible detection technology of the scraper conveyor during the operation of the scraper conveyor at home and abroad.
