侧扇型闸门曲轨卸载的可行性探讨

Feasibilily research on large skip loading with side fan gate and curve trail

目前采用侧扇形闸门曲轨卸载箕斗的最大载重为 17 5t。箕斗采用曲轨卸载 ,可明显降低休止时间 ,增加提升能力 10 %～ 30 %。对新井设计来说可降低选用等级 ,减少投资。对老矿来讲采用曲轨卸载可挖掘提升能力。侧扇型闸门可以解决在卸载时撒煤问题 ,结构简单事故少 ,并且使对井架的冲击也不大。 2 0t以上的大型箕斗采用曲轨卸载 ,从设计制造安装使用都是可行的。

Present, the largest load of skip with side fan gate and curvetrail is 17.5t.The load of skip uses curve trail. It can reduce stop-time and raise lift ability 10%～30%.It also can reduce capital for new mine.The side fan gate can prevent dropping coal when loading. It's structure is easy and trouble is less. And the shock to shaft fram is small. It's feasibility for 20t skip with curve trail load.
