千秋矿主井绞车是1958年安装投产的,设计装载系统是定容装载,经常出现提升超载现象。特别是装载湿煤、矸石等时,箕斗严重超载,造成绞车提不动,超出绞车的张力差,损坏电气设备,缩短钢丝绳和机械设备使用寿命。有时会造成装载闸门闭合不好,原煤放到井底,严重时会造成停产。2004年12月,千秋矿购进1台定量装载6.5t提升设备,安装以后,经常出现称重不准确、传感器不传 Qianqiu mine shaft winch was put into operation in 1958, the design of the loading system is a constant volume loading, often appear to enhance the phenomenon of overload. Especially when loading wet coal, waste rock, etc., the serious overloading of the skip causes the winch to move beyond the tension difference of the winch, damaging the electrical equipment and shortening the service life of the wire rope and the mechanical equipment. Sometimes it will result in poor closing of the loading gate. The raw coal will be placed in the well bottom and the production will be suspended in serious cases. December 2004, Qianqiu Mine purchased a quantitative loading 6.5t lifting equipment, after installation, often weighing is not accurate, the sensor does not pass
