采煤机滚筒调高液压系统的多功能液压锁

The hydraulic lock of multifunction for the shearer drum lift system

针对调高系统中液压锁开启时存在的压力冲击和下调速度过大及下调平稳性差等问题 ,通过分析研究 ,提出了一种新型液压锁 ,它具有结构紧凑。

When the hydraulic lock of the lift system to start,it is existed that the questions_the pressure impulse and the descend speed more big and the lower poise character badly.Passed the analysis and research,a kind of new hydraulic lock was put forward.It has the characteristics of smaller magnitude and multifunction.
