【摘要】：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。
[Abstract]:The selection rule of rope groove parameters of multi-layer winding hoisting system in ultra-deep mine is studied. In the process of multi-rope and multi-layer winding in ultra-deep mine, the tension of wire rope varies with the height of hoisting, the deformation of reel and the tension of wire rope affect each other, and the tension between layers of wire rope decreases. The mechanical model of the interaction between reel and wire rope tension is established, the deformation of wire rope is calculated, and the variation law of rope groove parameters is studied, which provides a theoretical reference for the design and selection of rope groove parameters of hoisting equipment in ultra-deep mine. The results show that the range of pitch is 1.032 ~ 1.414 d, the optimum diameter of rope slot is 1.032 6 d, and the contact depth is 0.329 d when winding six layers, and the transition acceleration curve between rings under different pitch is obtained by analyzing the influence of pitch on the transition acceleration between rings. The results show that the smaller the pitch is, the more favorable it is to reduce the intercycle transition acceleration. The research method and results can be used as reference for the design of rope slot and the selection of suitable rope slot parameters for super deep mine hoist.
