The invention provides a measuring system and method for a horizontal movement included angle of a scraper conveyor, and belongs to the field of automatic control over fully mechanized underground coal mining faces. The measuring system for the horizontal movement included angle of the scraper conveyor comprises a coal cutter and the scraper conveyor, the scraper conveyor comprises chutes, and each chute comprises a spillplate; the measuring system further comprises at least two sets of displacement sensors used for measuring the distances between the coal cutter and the spillplates and a main controller, and each set of the displacement sensors comprise at least two displacement sensors; the displacement sensors are fixedly arranged on the coal cutter and directly face to the spillplates, and the total length of each set of the displacement sensors is smaller than the length of half of the chute; each displacement sensor is electrically connected with the main controller. The invention further relates to the measuring method for the horizontal movement included angle of the scraper conveyor. According to the measuring system and method for the horizontal movement included angle of the scraper conveyor, the displacement condition of the chutes can be continuously obtained, whether the chutes of the scraper conveyor keep a straight line in the horizontal plane or not can be monitored to judge the displacement condition of the scraper conveyor, and the automated control over the fully mechanized coal mining faces of a coal mine is facilitated.
Description
technical field [0001] The invention relates to the field of automatic control of an underground fully mechanized coal mining face, in particular to a system and method for measuring the angle included in the horizontal movement of a scraper machine. Background technique [0002] The transportation of coal mining face is an important part of coal mine production. The main transportation machinery widely used in coal mining face in my country is scraper conveyor, referred to as scraper conveyor. If the scraper machine operates normally, the coal in the coal mining face can be transported out in time, and the production can go on normally. If a fault occurs, the entire working face will be shut down. The scraper machine is composed of main parts such as head wheel, tail wheel, chute, scraper chain and driving device, and also has a chain tightening device and a pushing device. The scraper machine is installed between the coal wall and the hydraulic support. The shearer recipr...
