Embodiment Construction

[0066] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0067] Implement the above-mentioned problem of positioning and attitude determination of shearers and scraper conveyors in fully mechanized mining working faces of coal mines, and propose a method for solving and predicting attitudes facing mining and transportation equipment in fully mechanized mining working faces. The method for positioning and determining attitude is The method is to obtain the shape by acquiring the posture data of the scraper conveyor in real time under the composite working condition of the uneven bottom plate of the fully mechanized mining face, and to obtain the shape through the contact and contact between the left and right support slide shoes of the shearer and the coal shoveling plate of the scraper conveyor. The coupling relationship between the left and right travel wheels and the pin row is used to solve the ...

Abstract

The invention relates to an attitude solving and predicting method of a fully mechanized coal mining face logging device. The method comprises the steps of under a composite working condition that a fully mechanized coal mining face floor is uneven, acquiring a shape through acquiring attitude data of a scraper conveyer in real time; through the contact of left and right support piston shoes of acoal cutter and a ramp plate of the scraper conveyer, and a coupling relation of left and right walking wheels and a pin row, solving attitude data of the coal cutter; marking a position of the coal cutter on the scraper conveyer through a change of a pitch angle of the coal cutter; according to a cutting top and bottom plate curve of a cycle of the coal cutter, predicting a shape and an arrangement state of the scraper conveyer of a next cycle, and carrying out more detailed and accurate dynamic monitoring on operation conditions of the coal cutter and the scraper conveyor; carrying out integrated positioning with an existing coal cutter positioning method, and solving and predicting attitudes of the fully mechanized coal mining face of the coal cutter and the scraper conveyer.

Description

technical field [0001] The invention relates to a detection method for mining and transporting equipment in a coal mine fully mechanized mining face during operation, in particular to a composite working condition where the bottom plate of a fully mechanized mining face is uneven, and is acquired by real-time acquisition of attitude data of a scraper conveyor The shape of the shearer is used to mark the position of the shearer on the scraper conveyor through the change of the pitch angle of the shearer, and then predict the posture of the next cycle of the scraper conveyor through the cutting floor curve of the shearer. Background technique [0002] As the core equipment of fully mechanized mining face equipment, the shearer plays a dominant role in production work. The position and posture information of the shearer determines the state of the scraper conveyor and the state of the hydraulic support. The operating position and posture of the fully mechanized mining face are ...
