摘要
针对煤矿井下轨道运输要求的超速保护或断绳保护问题,提出了一种矿用车辆自动液压制动系统的解决方案,介绍了该系统的原理、各部件的作用。该系统以高精度的液压阀检测、提取、过滤、放大、选择矿车的速度信号,进而通过制动闸完成夹轨制动。实际应用表明,该系统可在线检测矿车的速度,具有工作稳定可靠、测量精度高、易于操作、工作寿命长等优点。
In view of requirement of over-speed protection or rope breaked protection of underground track haulage,the paper put forward a solve scheme of automatic hydraulic braking system of vehicle.It introduced principle,functions of components of the system.The system uses high-precision hydraulic valve to test,extract,filter,amplify,choice speed signal of tram,then to complete clamping rail brake through brake valve.The practical application showed that the system can on-line measure speed of tram and has advantages of stable and reliable working,high measurement accuracy,easy operation,long working life.
