Coal mining height monitoring system of coal mining machine

Abstract

The invention discloses a coal mining height monitoring system of a coal mining machine. The coal mining height monitoring system comprises a machine body, rocker arms arranged at the two ends of themachine body, a roller arranged on one side of the rocker arms and a microprocessor arranged in the machine body. A fixed plate is fixed to the sides, away from the roller, of the rocker arms. A movable part is arranged on the side, away from the rocker arms, of the fixed plate. The movable part comprises a second movable plate, a first mounting plate and a second mounting plate, wherein the firstmounting plate and the second mounting plate are fixed to the two ends of the second movable plate. A first infrared displacement sensor and a second infrared displacement sensor are mounted on the sides, away from the rocker arms, of the first mounting plate and the second mounting plate correspondingly. The first infrared displacement sensor and the second infrared displacement sensor are electrically connected with the microprocessor through data wires. The microprocessor is in communication connection with terminal equipment.

Description

technical field [0001] The invention relates to a height monitoring system, in particular to a coal mining height monitoring system for a coal shearer. Background technique [0002] The coal shearer is a large and complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. This machine is used to cut the bottom groove in the coal mining face of the slow-dipping thin coal seam and extremely thin composite coal seam in general medium and small mines, so as to achieve the function of cutting and dropping coal. [0003] The height adjustment of the shearer drum is an important environment for the work of the shearer. At present, the adjustment of the drum is mostly adjusted by the staff through vision, and the accuracy is poor, resulting in a decrease in the working efficiency of the drum. This needs to be improved. Contents o...
