Automatic height adjusting device based on advanced hypocenter detection of shearer and applied to shearer as well as method

Abstract

The invention discloses an automatic height adjusting device based on advanced hypocenter detection of a shearer and applied to the shearer as well as a method. The device comprises a shearer-side signal acquisition device, a working-surface-side signal acquisition device and a height adjusting control module, wherein the shearer-side signal acquisition device acquires hypocenter signals of the shearer and solves absolute position parameters of the shearer under a coordinate system of a mine as well as geographic coordinates of center points of an upper drum and a lower drum of the shearer; the working-surface-side signal acquisition device acquires hypocenter signals, reflected by a wave impedance interface, of the shearer and solves absolute position parameters of a shearer body under an absolute coordinate system of the mine; the height adjusting control module adjusts height of the upper drum and the lower drum of the shearer automatically according to received signals. The automatic height adjusting device is high in precision and good in reliability and economic performance, and conditions are provided for realization of intelligent mining of a working face.

Description

technical field [0001] The invention relates to an automatic height adjustment device and method of a shearer based on advanced detection from a shearer seismic source, which belongs to the technology of automatic mining equipment. Background technique [0002] my country is a big country in coal mining and consumption, and coal mining machines are the main equipment for coal mining. The traditional mining face is mainly operated manually, which not only has high labor intensity and low efficiency, but also has an extremely poor working environment and a high degree of danger. Therefore, the development of automated and intelligent mining equipment is the general trend. Among them, the automatic adjustment of the shearer The high problem is the key to realize the intelligentization of mining face. At present, the automatic height adjustment methods of coal shearers mainly include dozens of methods such as cutting force response, natural gamma ray, radar, temperature, image,...

The traditional mining face is mainly operated manually, which not only has high labor intensity and low efficiency, but also has an extremely poor working environment and a high degree of danger. Therefore, the development of automated and intelligent mining equipment is the general trend. Among them, the automatic adjustment of the shearer The high problem is the key to realize the intelligentization of mining face

At present, the automatic height adjustment methods of coal shearers mainly include dozens of methods such as cutting force response, natural gamma ray, radar, temperature, image, etc. Among them, the methods based on cutting force response and natural gamma ray are widely used. The methods are all in the research stage, but the method based on the cutting force response requires coal rocks to have different Platts coefficients, and the method based on natural gamma rays requires the roof to have strong radioactivity, so the use is limited

The existing automatic height adjustment technology for coal shearers is mainly based on coal-rock interface recognition, which has a limited application range and large errors, and generally cannot fully meet the requirements of actual production
