摘要
矿井提升过程中松绳、断绳的事故时有发生,文中建立了斜井提升系统矿车卡住时的动力学模型,研究了斜井提升矿车卡住和紧急制动松绳时的钢丝绳动力学特性,对跑车防护问题进行了探讨和分析。
Accidents like rope slacking or breakage occur from time to time during hoisting process in the mine shaft,the paper describes a dynamic model for jamming of tramcar of the lifting system in the inclined shaft,studies the dynamic characteristics of steel rope when the tramcar gets stuck and emergency brake rope becomes loose,and discusses and analyzes prevention of carriage offset.
