摘要
为研究复杂工况下采煤机截割能耗特性,通过建立采煤机截割能耗模型,选用MG500/1180-WD型采煤机在不同工况下进行截割试验,实时采集齿轨销轴和惰轮轴的载荷数据,最后通过对不同工况下采煤机整机截割能耗的计算,得出如下结论:在保持其他工况不变的情况下,直线截割能耗随着牵引速度的增加而增加;斜切截割能耗值远超过直线截割能耗值;采煤机截割能耗除了受牵引速度、截割方式的影响外,还受煤岩硬度的影响,随着煤岩硬度的增加截割能耗也随之增加。研究结果为采煤机研发和使用提供理论基础,为煤矿行业科学高效生产提供理论依据。
In order to study the cutting energy consumption characteristics of coal miner under complicated conditions,the MG500/1180-WD shearer was cut out under different working conditions by collecting the cutting energy consumption model of coal mining machine.Pin and idler axle load data,and finally through the different conditions of coal miners cutting energy consumption calculation,the following conclusions:to keep the other conditions remain unchanged,the linear cutting energy consumption with With the increase of the traction speed increase;the oblique cut cutting energy consumption value is far more than the straight cutting energy consumption value;shearer cutting energy consumption in addition to the speed of traction,cutting mode,but also by the impact of coal hardness,With the increase in the hardness of coal and cutting cutting energy consumption also increased.The results of this study provide the theoretical basis for the development and use of shearer,and provide the theoretical basis for the scientific and efficient production of coal mining industry.
