洛阳义安矿业有限公司是1座设计年产120万t原煤的现代化矿井,井下某运输斜巷坡度22°,长120m,采用JD-2.5型提升绞车提升物料,每次提升2辆载重1t的矿车。该运输斜巷的挡车梯、阻车器由人工手动方式开启或关闭,通过人工升降配重吊桶实现挡车梯的起落,挡车性能较差,劳动强度大,操作不安全。因此,该矿对斜井挡车装置进行了技术改造。1改造方案通过矿用本安型电磁位置传感器对矿车进行实时监测,获取绞车运行信号。矿车运行时,触发传感
Luoyang Yian Mining Co., Ltd. is a modern mine with an annual output of 1.2 million tons of raw coal. A sloping slope of a transportation shaft is 22 ° and a length of 120m. JD-2.5 hoisting winch is used to lift the material, Mine car. The ladder for transporting the inclined roadway and the car stoppers are manually turned on or off, and the landing and fall of the ladder lift are realized through manual lifting and lowering of the counterweight bucket, the performance of the stop car is poor, the labor intensity is large, and the operation is not safe. Therefore, the mine has carried out technological transformation of the inclined well stop device. 1 transformation program through the mine intrinsically safe electromagnetic position sensor for real-time monitoring of the tub to obtain winch operation signal. When the tub is running, the sensor is triggered
