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.

Abstract

The invention discloses a scraper conveyor built-in scraper angle detection device and a detection method. The detection device includes a telescopic detection device, a signal detection unit and a remote processing unit. Both the telescopic detection device and the signal detection unit are provided with two sets , respectively set at both ends of the scraper; the signal detection unit detects the movement displacement of the telescopic detection device in real time and sends the signal through the wireless transmitting module, the wireless transmitting module and the wireless receiving module are used for data transmission, and the signal display processing module is used for real-time calculation The rotation angle value of the scraper is output and displayed at the same time, and the real-time measured rotation angle value is compared with the set safety threshold, and an alarm indication is issued when the safety threshold is exceeded. The invention has the advantages of simple and reliable structure, low cost, small space size, strong adaptability, good use effect, small amount of calculation of the measuring method, good real-time performance and high accuracy, and has wide practicability.

Description

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