摘　　要：根据煤矿井下迈步式自移机尾的实际工况,针对液压系统中存在部分执行元件距离液压控制与动力元件较远等问题,设计了一套综合反馈负载传感式液压控制系统,避免了因长距管路造成负载传感不可靠的问题,经实际验证可满足自移机尾的工作需要。综合反馈的方式一定程度上扩展了负载传感系统的应用场合,可为类似工况系统的设计提供参考。Based on the working condition of self-moving tail,aimed at the problems that some actuators are far away from the power and control component,a load-sensing hydraulic system which is based on a comprehensive feedback method was designed.It avoids the problem that the system will be unreliable due to long hydraulic pipeline,and also can meet needs for the self-moving tail working.To some extent,this method expends the application of load-sensing hydraulic system and also provides some references for design of similar systems.
