摘要
为了适应超深矿井钢丝绳的多层缠绕和平稳过渡的需求,提出了一种新的层间过渡原理.设计了5层缠绕钢丝绳的绳槽,分析了绳槽主要结构参数选择范围和方法.根据钢丝绳平稳过渡条件,提出折线区圆心角的二次螺线计算方法.研究结果表明:绳槽间隙取0. 03 d～0. 4 d,绳槽深度取0. 3 d～0. 5 d,上层钢丝绳的圈数比下层钢丝绳的圈数多2圈;新型双折线绳槽能够实现钢丝绳的多层缠绕和整齐排绳,根据二次螺线方法得到的折线区圆心角能够使钢丝绳在缠绕过程中无滑动现象.
To ensure the stable transition of the multi-layer steel wire rope in the ultra-deep mine hoist,a new interlayer transition principle was proposed. The five-layer wire rope transition device was designed,and the range and method of the main structural parameters of the rope groove were analyzed. Based on the requirement for the stable transition of wire ropes,the twice spiral method of the central angle of the fold line was presented. The results showed that the optimal groove clearance is 0. 03 d ～ 0. 4 d,and the groove depth is 0. 3 d ～ 0. 5 d. The number of loops of the upper layer wire rope was twice more than that of the lower layer wire rope. The new multi-layer transition device reveals both multi-layer winding and neat arrangement of wire ropes,and the central angle of the fold line obtained by the twice spiral method can help the wire rope avoid sliding in the winding process.
