Automatic control overhauling method of coal mining machine, electronic equipment oversized mining height coal mining machine

Abstract

The invention discloses an automatic control overhauling method of a coal mining machine, electronic equipment and an oversized mining height coal mining machine. The method comprises the steps that the information of a sensor installed on a rocker arm of the coal mining machine is obtained after responding to an event that the coal mining machine enters a overhauling mode; and lifting of the rocker arm of the coal mining machine is controlled according to the information of the sensor until the rocker arm of the coal mining machine is in a horizontal state. According to the automatic controloverhauling method of the coal mining machine, the electronic equipment and the oversized mining height coal mining machine, when the coal mining machine enters an overhauling mode, the rocker arm ofthe coal mining machine is automatically controlled to be in the horizontal state. The method can safely and rapidly detect and control the posture of the rocker arm and the coal mining machine can rapidly enter the overhauling mode, the whole process is safe, time and labor are saved, accurate control can be achieved, the accuracy of the oil filling amount of the rocker arm of the coal mining machine, especially the 8.8 m oversized mining height coal mining machine, can be well guaranteed, the service life of a rocker arm gear and a bearing is prolonged, and the starting rate of the coal mining machine is increased.

Description

Technical field [0001] The invention relates to the related technical field of coal shearers, in particular to an automatic control and maintenance method for coal shearers, electronic equipment and ultra-large mining height coal shearers. Background technique [0002] Shearer rocker gears and bearings are important parts of the shearer. The service life of gears and bearings is related to the opening probability of the shearer. Gear oil is the direct medium for lubricating and cooling the gears. The shearer works in the underground. In order to ensure the good working condition of the gear, it is necessary to regularly check the quality of the gear oil. When inspecting and replacing oil downhole, the intelligent shearer must first be in the inspection mode (rocker level), such as figure 1 Shown. Then observe the rocker arm refueling amount through the dipstick or oil window. [0003] Such as figure 2 As shown, when the rocker arm 1 is higher than the horizontal state, observe t...

AI Technical Summary

Problems solved by technology

[0009] Based on this, it is necessary to provide an automatic control maintenance method for the shearer in view of the technical problem that the rocker arm of the shearer cannot be guaranteed to be in a horizontal state in the prior art, resulting in too much or too little fuel oil. Electronic equipment and super large mining height shearer
