摘　　要：介绍目前我国立井箕斗普遍使用的上开式扇形闸门的开闭形式,对闸门开启受力分析,闸门开启力主要为斗箱内矿石作用在闸门上的压力及其与闸门的摩擦力、闸门自重、回转轴的摩擦力等。为不同载重的上开式扇形闸门箕斗在选型卸载形式时提供依据。Introduces the vertical shaft skip in China on the widespread use of open the valve open form. The stress analysis of the gates open gate opening force mainly for bucket ore in the effect on the gate of the pressure and the friction to the gate,the gate weight,rotating shaft friction, etc.. It provides the basis for the different loading of the upper open sector gate skip in the form of optional unloading.

关 键 词：扇形闸门 外动力 卸载曲轨
