随着社会对能源的需求不断加大,矿井开采深度也在不断增加。为满足矿井提升高度不断增大的需求,矿井提升机必须增加卷筒宽度,或者加大卷筒直径。增加提升机的卷筒宽度,造成主轴长度加大,为避免主轴的刚度下降,就必须加大主轴直径;加大提升机的卷筒直径,增大了容绳量,造成卷筒质量大大增加。这两种情况均增加了成本。 As society’s demand for energy continues to increase, mining depth is also increasing. To meet the ever-increasing demands of mine hoists, mine hoists have to increase roll width or increase roll diameter. Increase the drum width of the hoist, resulting in increased spindle length, in order to avoid the decline in the rigidity of the spindle, you must increase the spindle diameter; increase hoist drum diameter, an increase of capacitance rope volume, resulting in greatly increased reel quality . Both of these situations add to the cost.
