深井钢丝绳罐道提升容器水平偏移和安全间隙计算
|
摘要
以思山岭铁矿双箕斗主井提升容器安全间隙计算为背景,引入罐道绳刚性系数,分析刚性系数变化规律,计算出罐道绳刚性系数最小值;对引起提升容器水平偏移的各主要因素,分别作了计算,得出了相应的提升容器水平位移和总位移;通过引入安全间隙系数,计算出提升容器运行所需的安全间隙。
Based on the calculation on the safety clearance of the hoisting container in the double skip shaft of Sishanling Iron Mine as a background,a rigidity coefficient of the steel rope guide was applied to analyze the variation law of the rigidity coefficient and to calculate the rigidity coefficient minimum of the guide steel rope.The calculations were conducted on the each major factor to cause the horizontal offset of the hoisting container and the horizontal displacement and total displacement of the relevant hoisting container were obtained.The safety clearance coefficient was applied to calculate the safety clearance required by the operation of the hoisting container.
