开采4~8 m急斜煤层,采用F3200/17.5/27F型放顶煤液压支架,工作面放落煤运输到顺槽平巷转载机中的距离较短,现有刮板机不适合,采用乳化液马达直接驱动可使整机结构大为简化,有利于超短距离运输。由于超短刮板输送机通常都是满载启动,故搭建“等效变量泵”和定量乳化液马达容积调速回路实现恒转矩输出,以满足超短刮板输送机满载启动的要求。
Mining 4 ~ 8 m steep coal seam, the use of F3200 / 17.5 / 27F caving coal hydraulic support, face coal coal transport to the slot conveyor smoothing short distance, the existing scraper is not suitable, the use of Emulsion motor direct drive can make the whole structure is greatly simplified, is conducive to ultra-short-distance transport. Because of the short-short scraper conveyor is usually full load start, it build “equivalent variable pump ” and quantitative emulsion motor volume control circuit to achieve constant torque output, in order to meet the short-scraper conveyor full load start requirements .
