摘要
针对煤矿井下薄煤层综采工作面生产空间小、工人劳动强度大、人工控制条件下煤炭产出效率低等问题,提出在四台矿开发研制全自动无人电液综采设备方案,即电液控液压支架的液控系统采用差压式结构的控制阀,支架结构件采用Q550钢板以减轻支架自重,同时设计了人机界面,便于故障分析及检修,电液控换向阀与控制器集成一体。该方案通过地面试运转,支护效果良好,自动化系统得到了充分利用。
According to the problems of the thin coal seam in the coal mine of the Datong coal mine group, such as the little production space, the huge labor intensity and the low output efficiency. Put forwards the program of fully mechanized coal mining equipment in Sitai Mine, which is the hydraulic control system using the differential pressure type structure of the control valve, steel Q550 frame is used to reduce the weight of the bracket, the man- machine interface is designed for fault analysis and maintenance, electronic-hydraulic control valve and controller integration, etc. The program has been applied through the test interview, received good support effect, the automation system has been fully utilized.
