[0005] To achieve the above objectives, this utility model provides the following technical solution: a fatigue-resistant elevator wire rope, comprising an outer wire layer and an inner wire layer. The outer wire layer includes an inner partition layer, an outer wrapping layer, and outer strands of wire. The inner partition layer and the outer wrapping layer form an annular cross-section. The outer strands of wire are distributed in an annular pattern between the inner partition layer and the outer wrapping layer. The inner wire layer includes an inner wrapping layer, inner wires, and surrounding wires. The inner wires and surrounding wires are disposed inside the inner wrapping layer.

[0006] Preferably, the inner steel wire is located in the middle of the inner wrapping layer, and the inner steel wire surrounds the outer side of the inner wrapping layer.

[0007] Preferably, the outer layer of the steel wire further includes filler strands, which are disposed in the gaps between adjacent outer strands.

[0008] Preferably, the inner layer of the steel wire further includes a filling gel, which fills the interior of the inner wrapping layer.

[0009] Preferably, the inner surface of the inner partition layer is attached to the outer surface of the inner wrapping layer, and a limiting component is provided between the inner partition layer and the inner wrapping layer. The limiting component includes a limiting block and a limiting groove.

[0010] Preferably, the limiting blocks are distributed on the outer surface of the inner wrapping layer and embedded in the limiting slots opened on the inner surface of the inner partition layer.

[0011] Preferably, the outer strand of steel wire includes a steel wire body and a galvanized layer, wherein the galvanized layer is disposed on the outer surface of the steel wire body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing a double-layer structure consisting of an outer layer and an inner layer of steel wire, the overall strength and fatigue resistance of the wire rope can be improved. Even if one layer is damaged, the other layer can still provide emergency support. The damaged layer can be replaced afterward, which significantly improves the overall safety of the wire rope during use. Attached Figure Description
