目前焦作矿务局已有70％以上的竖井提升容器采用了钢丝绳罐道作导向装置。它具有结构简单、安装方便、使用寿命长,维护费用低等优点。但由于受到拉紧方式某种缺点的限制,致使在一些设计中不得不改选其它罐道形式,如金属罐道和木罐道。所以这就是我们要改进拉紧装置的主要原因。 一、目前我局钢丝绳罐道拉紧装置的形式: 1、螺旋拉紧装置——该装置方式简单可靠,但拉紧力受到一定的限制,不能适应张力的变化,调整很不方便。
At present, Jiaozuo Mining Bureau has more than 70% of the shaft to enhance the container using steel wire rope as the guide device. It has the advantages of simple structure, convenient installation, long service life and low maintenance cost. However, due to certain shortcomings of the tightening method, other designs of cans have to be re-elected in some designs, such as metal cans and wood cans. So this is the main reason we want to improve the tensioning device. First, the current Bureau of our rope tightening device in the form of wire rope: 1, spiral tensioning device - the device is simple and reliable, but the tension is subject to certain restrictions, can not adapt to changes in tension, the adjustment is not convenient.
