Scrapping plate conveyor dynamic straightening method based on absolute motion trajectory of coal cutter

Abstract

The invention provides a scrapping plate conveyor dynamic straightening method based on the absolute motion trajectory of a coal cutter and belongs to a scrapping plate conveyor dynamic straightening method for a full-mechanized mining face. In the dynamic straightening method, a positioning device mounted on the coal cutter is utilized, so as to conduct real-time monitoring to the moving trajectory of the coal cutter along the scrapping plate conveyor; a signal processing circuit analyzes the dynamic position data of the coal cutter moving along the scrapping plate conveyor under the set spatial coordinate system; the absolute motion trajectory curve of the coal cutter and target reference motion trajectory of the quire under the geographical spatial coordinate system are concluded; a micro controller draws a target reference motion trajectory of a next quire according to the target reference trajectory and the working face coal bed terrain; the displacement distance of each hydraulic support is calculated; the micro controller controls an electro hydraulic control system via an output circuit; the electro hydraulic control system controls each bracket controller, so as to push a jack forward and enables the scrapping plate conveyor to meet the linear requirement. The positioning device on the coal cutter detects the orientation of the full-mechanized mining face in the geographical spatial coordinate system, so that adjusting false inclination of the full-mechanized mining face can be achieved.

Description

technical field [0001] The invention relates to a dynamic straightening method of a scraper conveyor in a fully mechanized coal mining face, in particular to a dynamic straightening method of a scraper conveyor based on the absolute motion track of a shearer. Background technique [0002] At present, in the major coal-producing countries in the world, most of the working faces adopt the long-arm coal mining method, that is, the fully-mechanized mining face characterized by the electro-hydraulic control of the hydraulic support and the linkage between the shearer and the hydraulic support. In the coal mine production process, the method to achieve normal and efficient production of the fully mechanized mining face is "three straight and one leveling" of the fully mechanized mining face: the hydraulic support, the cut coal wall, and the scraper conveyor are kept on a straight line. [0003] The scraper conveyor of the fully mechanized mining face is not only the running guide ...
