QS-650清筛机挖掘链液压驱动系统的改进

The Research of Excavating Chain Hydraulic Drive System for QS-650 Cleaning Machine

QS-650清筛机是我国目前铁路线路维修与保养中使用最多的清筛设备。针对此清筛机挖掘链驱动液压系统挖掘力不足和稳定性不够好的情况,对挖掘链液压驱动系统做了改进。将开式的液压系统改为闭式的静液压系统,提高天窗作业的效率和挖掘的高效性,降低故障发生率,提高清筛机作业效率,延长其使用寿命,降低铁路线路维护的风险,同时为挖掘链液压驱动系统的全面改进提供基础研究。

QS -650 cleaning machine is the most frequently used ballast cleaning equipment for repair and ma- intenance of railway lines in the current. In this paper, this cleaning machine digging chain drive the hydraulic sys- tem and the stability of digging force shortage situation is not good enough, for excavating chain hydraulic drive system has been improved. Changing the open hydraulic system to the closed hydraulic system to improve the efficiency and skylights mining operations efficiency. It can also reduce the failure rate, improve the cleaning machine operating effi- ciency, extending its life, reduce the risk of the railway line maintenance, while providing the basic research for exca- vation overall improvement chain hydraulic drive system.
