Adjusting system for tunneling posture of coal mining machine

Abstract

The invention discloses an adjusting system for tunneling posture of a coal mining machine. The adjusting system comprises a vibration detecting module, a laser detecting module, an ultrasonic detecting module, a data acquisition unit, an industrial control computer and a remote communication module, wherein the vibration detecting module is used for obtaining the conditions of a coal seam and tunneling vibration; the laser detecting module is used for obtaining an inclined angle of the coal seam; the ultrasonic detecting module is used for obtaining the tunneling attitude of the coal mining machine; the data acquisition unit is used for acquiring sensor signals obtained by the vibration detecting module, the laser detecting module and the ultrasonic detecting module and transmitting the sensor signals to the industrial control computer; the industrial control computer is provided with a coal petrography identification analysis module, a three-dimensional direction seeking module and an posture computing module; a PLC (Programmable Logic Controller) control unit is connected with the industrial control computer and is used for adjusting the tunneling posture of the coal mining machine; the remote communication module is connected with the industrial control computer and is used for transmitting coal petrography identification information obtained by calculation of the coal petrography identification analysis module and tunneling posture data, obtained by the posture computing module, of the coal mining machine in the industrial control computer to a remote monitoring terminal. The adjusting system disclosed by the invention provides more detailed information for the tunneling posture adjustment of the coal mining machine so as to better avoid the faults of the coal mining machine.

Description

technical field [0001] The invention relates to the technical field of attitude adjustment of large machinery, in particular to a coal mining machine excavation attitude adjustment system. Background technique [0002] The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. At present, the mining of thin coal seams and extremely thin coal seams mainly relies on the drum shearer, which has the problem of drilling tool deflection during use. Due to special circumstances such as dust, it is easy to cause more misjudgments and operational errors by workers, resulting in the inability of the shearer to drill in the specified direction. The real-time excavation attitude adjustment system realizes the real-time deviation correction and adjustment of the auger drilling tool. The existing attitud...
