Embodiment Construction

[0039] The health index of the shearer is an indicator indicating the health status of the shearer. It adopts a percentage system and can indicate the overall health of the shearer system in real time. This value is mainly calculated through a set of complex empirical formulas based on data such as the cumulative working time of the shearer, daily fault conditions, and the overload and overheating time of each motor.

[0040] At the same time, in order to facilitate the observation of coal mining machine users, in addition to the percentile representation method, the health indicator also has a simple three-color representation method. Text blocks are used to indicate the current health status at a prominent position. When the health degree is 80 When -100 points, it is represented by the word "health" with a blue background, when it is 60-80 points, it is represented by the word "alarm" with a yellow background, and when it is 0-60 points, it is represented by the word "failur...

Abstract

The invention discloses a method for evaluating a health degree of a coal cutter. The health degree of the coal cutter is an indicator reflecting a health state of the coal cutter, adopts a centesimal system and can indicate the overall health condition of the coal cutter system in real time. When the coal cutter is failure-free, the health degree is equal to J=Jo-D*(Ty / 16+Tg / 16+Ma / 2+Mt / 2+Fa / 5); when the coal cutter is in serious failure occurrence, the health degree is equal to J*60%*(1-Fm / 10)=J*(60-6Fm) / 100; and when the coal cutter is in ordinary failure occurrence, the health degree is equal to J*(1-Fn / 20*40%)=J*(100-2Fn) / 100.

Description

technical field [0001] The invention belongs to the technical field of coal shearer equipment, and in particular relates to a method for evaluating the health of a coal shearer. Background technique [0002] The application document with the publication number CN103527194A discloses "a real-time monitoring and intelligent evaluation system for the health of an electric traction coal mining machine, which is characterized in that it includes a coal mining machine, a wireless monitoring device, a slotting upper computer and an above-ground monitoring center; In the above system, the shearer belongs to the monitored object, and the sensors including voltage sensor, current sensor, temperature sensor, flow sensor, pressure sensor, position and attitude sensor, and vibration sensor are arranged in the body of the shearer in a distributed manner, constituting The left rocker arm monitoring unit, the right rocker arm monitoring unit, the high-voltage control box monitoring unit, th...
