Abstract

Koepe hoist multilayer strand balance tail rope, including hemp core, central strand, internal layer stock, outer layer strand；The periphery of hemp core is provided with central strand, the periphery of the centrally disposed stock of internal layer stock, and outer layer strand is arranged on the periphery of internal layer stock；The quantity of the central strand is stock, and the quantity of internal layer stock is stock, and the quantity of outer layer strand is stock；The central strand, internal layer stock, the shallow bid structure all same of outer layer strand；The shallow bid is followed successively by from the inside to the outside：Shallow bid central core is 1 steel wire, and shallow bid internal layer is 6 steel wires, and shallow bid packed layer is 6 finer wires, and shallow bid outer layer is 12 steel wires.Koepe hoist provided by the utility model multilayer strand balance tail rope, the bending property and twisting property of monofilament are significantly improved, and steel wire rope shallow bid is linear contact lay, and the integral fatigue life of steel wire rope is obviously prolonged.

Description

Koepe hoist multilayer strand balance tail rope

Technical field

The utility model belongs to the technical field of special wire rope, and in particular to koepe hoist is balanced with multilayer strand Tail rope.

Background technology

With the development of Modern Mineral extraction industry, mining depth was originally deeper, and single lift amount is increasing, elevator rule Lattice are increasing, and lifting head rope is more and more thicker, so tail rope requires also more and more thicker；With the continuous overstriking of wirerope diameter, Filament diameter is increasing, and the fatigue life of steel wire rope substantially shortens.

Utility model content

The purpose of this utility model is to provide koepe hoist multilayer strand balance tail rope, and its is rational in infrastructure, raw It is low to produce cost.

To achieve these goals, the utility model employs following technical scheme：Koepe hoist multilayer strand Balance tail rope, including hemp core, central strand, internal layer stock, outer layer strand；The periphery of hemp core is provided with central strand, and internal layer stock is centrally disposed The periphery of stock, outer layer strand are arranged on the periphery of internal layer stock；The quantity of the central strand is stock, and the quantity of internal layer stock is stock, outer layer The quantity of stock is stock；The central strand, internal layer stock, the shallow bid structure all same of outer layer strand；The shallow bid is followed successively by from the inside to the outside： Shallow bid central core is 1 steel wire, and shallow bid internal layer is 6 steel wires, and shallow bid packed layer is 6 finer wires, and shallow bid outer layer is 12 steel Silk.

Further, the steel wire rope shallow bid is linear contact lay.

Beneficial effect：Koepe hoist provided by the utility model multilayer strand balance tail rope, the bendability of monofilament It can be significantly improved with twisting property, steel wire rope shallow bid is linear contact lay, and the integral fatigue life of steel wire rope is obviously prolonged.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of shallow bid.

In figure, 1, hemp core, 2, central strand, 3, internal layer stock, 4, outer layer strand；

101st, shallow bid central core, 102, shallow bid internal layer, 103, shallow bid packed layer, 104, shallow bid outer layer.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.

As shown in Figure 1, 2, koepe hoist multilayer strand balance tail rope, including hemp core 1, central strand 2, internal layer stock 3, Outer layer strand 4；The periphery of hemp core 1 is provided with central strand 2, the periphery of the centrally disposed stock 2 of internal layer stock 3, and outer layer strand 4 is arranged on internal layer stock 3 periphery；The quantity of the central strand 2 is 6 strands, and the quantity of internal layer stock 3 is 11 strands, and the quantity of outer layer strand 4 is 17 strands.

The central strand 2, internal layer stock 3, the shallow bid structure all same of outer layer strand 4；The shallow bid is followed successively by from the inside to the outside：It is small Stock central core 101 is 1 steel wire, and shallow bid internal layer 102 is 6 steel wires, and shallow bid packed layer 103 is 6 finer wires, shallow bid outer layer 104 be 12 steel wires.

The steel wire rope shallow bid is linear contact lay.

Koepe hoist provided by the utility model multilayer strand balance tail rope, using 34x25Fi+FC structures, steel Cord minimum breaking force can reach >=0.308xD²xR₀/1000KN（Wherein D represents steel wire rope nominal diameter, unit mm, R₀Represent steel wire rope Nominal Tensile, unit MPa）

The bending property and twisting property of monofilament are significantly improved, and the integral fatigue life of steel wire rope is good.

It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model Within enclosing.
