2JK-3/20提升机深度指示器的改造

Reconstruction of depth indicator in 2JK-3/20 hoister

提升系统是金属矿山地下开采重要的组成部分,而提升机的深度指示对于提升高度的准确定位更是不可或缺。文中针对五龙金矿开拓、生产及提升系统实际,通过增大提升机深度指示器的传动比、缩短每个中段的指示长度,对提升机深度指示器进行了改造。改造后的提升机深度指示器满足了竖井继续延深的需要。

The hoisting system is an important component of underground mining system. The depth indication of hoister is very important to position the hoisting height. According to the actuality of development system, production system and hoisting system in Wulong gold mine, some reconstruction works were carried out in the depth indicator of hoister, such as increasing the transmission ratio of the indicator and reducing the indication length of every sublevel. As a result, the indicator met the need of shaft extension.
