双绳多层缠绕式矿井提升机钢丝绳最佳出绳型式

缠绕式超深矿井提升机钢丝绳出绳型式的确定对于矿井提升机主轴及其系统安全可靠运行具有重要作用。针对钢丝绳出绳型式对主轴承载优劣的问题，通过建立力学模型、数值计算与有限元分析相结合的方法推导了主轴变载荷计算通式，编写了 16 种工况的数值计算程序并进行仿真计算，由此比较提出了钢丝绳的最佳出绳型式。研究表明：提出的主轴变载荷计算通式对于 16 种工况下提升(或下放)时左、右卷筒都适用；采用 S 曲线速度或多阶段速度运行有利于主轴运行的稳定性；腹板对称或非对称( L8,L10 差值 150 mm以内)时，游筒两绳区左、下出绳，固筒两绳区右、上出绳为最佳出绳型式。研究方法和成果有利于确定主轴受载情况，对于设计主轴以及确定超深矿井提升机的出绳型式可提供理论参考。

Best fixation mode of wire rope for double-rope multi-layer winding mine hoist

The determination of wire rope’s fixation mode of ultra-deep winding mine hoist plays an indispensable role in the safe and reliable operation of the shaft hoist spindle and its system.Aiming at the problem that rope’s fixation mode has an effect on the bearing capacity of spindle,the comprehensive research methods of mechanics model have been established,numerical simulation and finite element analysis have been used to derive the general formula of the variable load of the spindle,16 kinds of working conditions have been programmed and the simulation analysis has been carried out,and then the best fixation mode of wire rope is proposed by comparison.Research shows that the general formula proposed is suitable for the left and right drum under 16 kinds of working conditions when lifting or lowering.The selection of S-curve speed or multi-stage speed operation benefits the stability of spindle.The best fixation mode is lower left fixation for mobile drum’s double-rope area and upper right fixation for fixed drum’s double-rope area when the web is symmetrical or asymmetrical (difference of L8, L10within 150 mm).Research methods and results will benefit the instantaneous load of spindle,and offer theoretical references to design spindle and determine the rope’ fixation mode of ultra-deep mine hoist.
