两象限电牵引采煤机制动控制的方法

Control Way of Dual Quadrant Electrical Traction Coal Cutter's Braking

分析了两象限电牵引采煤机在倾角较大的工作面上牵引运行时存在的一些问题,并就如何利用电牵引采煤机中的速度反馈信号和电流反馈信号以及液压控制系统提出了一种新的、简单易行的解决方法。

The problems when the electrical traction coal cutter speeds alone the steep slope in dual quadrant is analyzed, and provide a new and simple way which uses the current feedback signal, speed feedback signal and the hydraulic driving system of the electrical traction coal cutter shearer.
