摘要

针对目前开采0.8 m左右煤层的采煤机装机功率、机面高度、过煤空间以及运行稳定性之间不能兼顾的矛盾，介绍了一种截割部全悬，机身半悬的整机布置方式。并针对开采0.8 m煤层的特殊工况，对采煤机进行了整机布置结构适应性研究、摇臂壳体适应性研究、行走部适应性研究、电控系统适应性研究。研究结果表明：研制的开采0.8 m煤层的薄煤层采煤机，装机功率可达445.5 kW，机面高度≤600 mm，过煤空间≥200 mm，采煤机重心在槽帮上方，运行稳定，摇臂壳体采用CrNiMo系高强度材料，电控系统采用非机载控制和分段遥控控制，对于开采0.8 m左右的煤层具有良好的适应性，可满足中小煤矿0.8 m左右薄煤层工作面年产30万t的需求。
Abstract

In order to deal with the incompatibility of the installed power，the machine height，the coal space and the operational stability of the coal mining machine used in mining a coal seam of about 0.8 m，this paper introduced a machine layout with the cutting part fully suspended and the fuselage half suspended，and in view of the special working conditions of the 0.8 m coal seam，the adaptability of the whole machine layout，the adaptability of the rocker shell，the adaptability of the walking section and the adaptability of the electronic control system were studied.The research results show that the thin coal seam shearer for mining 0.8 m coal seam developed in this study has an installed power of 445.5 kW，a machine height of ≤600 mm，a coal space of ≥200 mm，and a center of gravity of the shearer above the tank and runs stably.The rocker arm shell adopts CrNiMo high-strength material，and the electronic control system uses non-airborne control and segmented remote control，so it has good adaptability for mining coal seam of about 0.8 m，and can meet the needs of thin coal seam of about 0.8 m in small and medium coal mines with an annual output of 300 000 tons.
