研究超深矿井多层缠绕提升系统绳槽参数的选取规律。在超深矿井多绳多层缠绕提升过程中,钢丝绳拉力不断地随提升高度变化,卷筒变形和钢丝绳张力相互影响,及钢丝绳层间拉力降低,建立卷筒和钢丝绳拉力相互影响的力学模型,计算钢丝绳变形量,研究绳槽参数变化规律,为超深矿井提升装备卷筒绳槽参数设计和选取提供理论参考。研究结果表明:在缠绕6层时,节距取值范围为1.032 6~1.414 d,绳槽最佳直径为1.032 6 d,接触深度为0.329 d;通过分析节距对圈间过渡加速度的影响,得到不同节距下圈间过渡加速度曲线,结果表明,节距越小对减小圈间过渡加速度越有利。研究方法和结果可为超深矿井提升机绳槽的设计、合适的绳槽参数选取提供参考。
This paper studies the selection rule of rope groove parameters for the multi-layer winding hoisting system of ultra-deep mine.In the process of multi-rope and multi-layer winding lifting,the tension of the wire rope is constantly changing with the lifting height and the deformation of the drum and the tension of the wire rope affects each other.In considering the decrease of rope＇s tension in layers,the mechanical model of the mutual influence of drum and wire rope is established to calculate the deformation of wire rope and to study the variation of rope parameters,which provide theoretical reference for the design and selection of the parameters of the rope groove of drum.The results show that the pitch ranges from 1.032 6 d to 1.414 d,the best diameter of the groove is 1.032 6 d and the contact depth is 0.329 d.By analyzing the effect of pitch on the inter-circle transition acceleration,the transition curve of inter-circle transition is obtained.The results show that the smaller the pitch is,the more favorable the acceleration is.The research methods and results can effectively guide the design of the rope groove of ultra-deep mine hoist and the selection of appropriate rope groove parameters.
