Abstract

The invention provides a novel electric control system for monitoring automatic tensioning of a chain of a scraper conveyor. The novel electric control system for monitoring the automatic tensioning of the chain of the scraper comprises a first pipeline connected with an emulsion pump station and a second pipeline connected with an oil outlet pipeline, the first pipeline is communicated with the second pipeline, a control valve and a recovery valve are arranged between the first pipeline and the second pipeline, and the second pipeline is communicated with a third pipeline and a fourth pipeline. The novel electric control system for monitoring automatic tensioning of the chain of the scraper conveyor has a good damping and buffering effect, fluctuation and impact of the scraper conveyor system in the starting process are remarkably reduced, the accident rate of slipping, deviation and disengagement caused by loosening of the conveying chain during starting is greatly reduced, and the service life of the scraper conveyor system is prolonged. The optimized tensioning device ensures the stability and the reliability of the scraper conveyor in the working process, and the service life of the scraper chain is prolonged.

Description

technical field [0001] The invention relates to the field of coal mine automation, in particular to a novel electronic control system for monitoring the automatic tensioning of scraper chains. Background technique [0002] The scraper conveyor is the equipment used for conveying coal under the mine. Its working principle is that the motor drives the chain, the chain drives the scraper to reciprocate, and the scraper pushes the coal to be transported. [0003] The scraper conveyor chain is the moving traction mechanism of the scraper conveyor, and it is also the part of the scraper conveyor system that is most likely to fail and cause the scraper conveyor to fail. [0004] In the related technology, the start and stop of the scraper conveyor and the change of the load on the conveyor will cause a certain elongation and tension of the scraper chain. Therefore, if the elongation or tension of the conveyor chain cannot be timely If the compensation is performed, the tension of ...
