一、前言紧急制动是多绳摩擦提升最容易打滑的状况,尤其是在重物下放情况下的紧急制动。矿井双箕斗提升偶尔有重物下放情况发生,付井双罐笼重物下放情况较多。近年来,我国采矿工业迅猛发展,正在设计和建设一批大型及特大型矿井,一般付井罐笼为多层提升或下放重物。经常碰到罐笼重物下放紧急制动最小防滑自重应该选取多大,以及如何计算等问题。为了经济合理的选用提升机及钢丝绳,运行中又不发生打滑现象,合理地选取提升容器最小防滑自重是很重要的。 I. INTRODUCTION Emergency braking is the easiest slippery condition for multi-rope frictional lifting, especially in the event of heavy braking. Mine double skip to enhance occasional occasions heavy decentralization occurs, pay well double cage weight decentralized situation more. In recent years, the rapid development of China’s mining industry is being designed and construction of a number of large and extra large mines, the general pay well cage for the multi-layer lifting or heavy load. Often encounter the heavy weight of emergency cage brake should be selected to minimize the amount of weight, and how to calculate and other issues. In order to choose the elevator and wire rope economically and reasonably, the phenomenon of skidding does not happen during the operation. It is very important to choose the minimum non-slip weight of the container reasonably.
