Abstract: 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 0.03d~0.4d， and the groove depth is 0.3d~0.5d. 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.

Key words: wire rope, multilayer winding, stable transition, double-folded groove, structural design
