Automatic detection method for moving up or down of conveyor in coal mining face

Abstract

The invention discloses an automatic detection method for moving up or down of a conveyor in a coal mining face. S1, an inertial navigation system is installed on a coal mining machine, and a course angle sensor is installed on a hydraulic support, and each course angle sensor is numbered according to the arrangement sequence of the hydraulic support; S2, determining the error range; S3, establishing the coordinate system; S4, optimizing the coordinate points; S5, judging whether the transport plane is going up or down. The invention has the advantages of simple operation, fast response and good real-time performance. It can not only monitor whether the entire conveyor is going up or down, but also monitor whether the partial conveyor is bent or the hydraulic support is tilted, so as to adjust in time.

Description

technical field [0001] The invention relates to a coal mine fully mechanized working face conveyor, in particular to an automatic detection method for the upward or downward movement of the coal mining face conveyor. Background technique [0002] The coal seams mined in the fully mechanized coal mining face are naturally formed, and the thickness distribution of the coal seams is uneven and irregular, and has a certain slope. Therefore, the fully mechanized coal mine working face is divided into near-horizontal layer, gently inclined layer, inclined layer and steeply inclined layer according to the inclination layer of the coal seam. Under different slopes, the shearer, conveyor, and hydraulic support of the fully mechanized face equipment will slide down or move up to varying degrees under the action of their own gravity, coal cutting resistance and other factors. If it cannot be adjusted in time, the transporter will stand up to the upper and lower lanes, making it imposs...

AI Technical Summary

Problems solved by technology

However, due to the relatively large coal dust in the fully mechanized mining face, which affects the penetration of the laser, resulting in inaccurate laser measurement, this method is difficult to implement in the fully mechanized mining face with complex environments

In addition, the accuracy of the automatic control method of this patent is relatively poor; because the fully mechanized mining face is relatively long, generally 100-200 hydraulic supports are required to arrange and support, so it is impossible to detect the slide and tilt of local hydraulic supports in time, which also cannot Accurately give the pushing distance of each hydraulic support and accurately adjust the upward or downward movement of the conveyor

At present, the upward and downward movement of the fully mechanized mining face mainly depends on manual judgment and adjustment, which cannot meet the intelligent and unmanned requirements of the fully mechanized mining face
