Description
Technical field
The utility model belongs to steel wire rope technical field, is related to a kind of steel wire rope composite fibre wire rope core.
Background technology
Currently, Fibre-core cable is by its excellent flexibility and High oleic is carried in wire rope for cableway, vertical inclined shaft
Steel wire rope and all kinds of important carryings are risen with occupying important share in steel wire rope.Wherein, fiber wire rope core quality is to influence steel wire
One of the key factor of rope total quality, in the market there are two types of existing Fibre-core cables, one is sisal fiber core wires
Rope, by shock loading or is shelved for a good while, wire rope core easily loses toughness and supporting role；Another kind is polypropylene cores steel wire rope,
Immersion oil rate is low, oil storage poor performance, is susceptible to the rotten phenomenon of grain.During existing Fibre-core cable use, because wire rope core loses
Steel wire rope problem happens occasionally caused by effect, and certain economic loss is therefore also brought to user.
Utility model content
The purpose of this utility model is to provide a kind of steel wire rope composite fibre wire rope core, improves steel wire rope composite fibre
The service life of wire rope core.
The utility model is the technical scheme adopted is that a kind of steel wire rope composite fibre wire rope core, including core strand, core strand by
7-12 root sisal hemp sliver twistings are constituted, and core strand periphery packet, which is twisted, four silent partners, and silent partners is by the netted polypropylene sliver twisting of 8-14 roots
It constitutes, steel wire rope composite fibre wire rope core laying pitch coefficient is 2.8~3.2, and the laying pitch coefficient of core strand and silent partners is 9.2~9.8.
The utility model is also characterized by
Core strand it is a diameter of：
d0=k0×dFC (3)
In formula (3), k0For core strand diameter design coefficient, value 0.35；dFCFor steel wire rope composite fibre wire rope core diameter.
Silent partners it is a diameter of：
d1=k1×dFC (4)
In formula (4), k1For silent partners diameter design coefficient, value 0.40；dFCFor steel wire rope composite fibre wire rope core diameter.
Sisal hemp sliver whole immersion oil, oil content reach 40% or more.
Netted polypropylene sliver immersion oil part is no less than 50%, and oil content reaches 24%.
The utility model has the beneficial effects that：A kind of steel wire rope of the utility model is with composite fibre wire rope core by sisal fiber item
It is formed with Netted flap item, has excellent oil storage performance and shock resistance；The steel wire rope of the utility model is used
Composite fibre wire rope core primary twisting is molded, and wire rope core compactness is high, and diameter uniformity and support performance are good, its comprehensive performance is made to obtain
To significantly improving；The utility model is suitable for a variety of carrying shaped steel wire ropes, and level of application is wide；Most of all, the utility model
Steel wire rope greatly improved with the composite fibre wire rope core service life, save production cost.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of steel wire rope composite fibre wire rope core cross section of the utility model.
In figure, 1. core strands, 2. silent partners.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model a kind of steel wire rope composite fibre wire rope core, as shown in Figure 1, including core strand 1, core strand 1 is by 7-12 roots
Sisal hemp sliver twisting is constituted, sisal hemp sliver whole immersion oil, and oil content reaches 40% or more, and 1 periphery of core strand packet, which is twisted, four silent partners
2, silent partners 2 is made of the netted polypropylene sliver twisting of 8-14 roots, and netted polypropylene sliver immersion oil part is no less than 50%, oil content
Reach 24%, steel wire rope composite fibre wire rope core laying pitch coefficient is 2.8~3.2, and the laying pitch coefficient of core strand 1 and silent partners 2 is 9.2
~9.8.
Core strand 1 it is a diameter of：
d0=k0×dFC (3)
In formula (3), k0For core strand diameter design coefficient, value 0.35；dFCFor steel wire rope composite fibre wire rope core diameter.
Silent partners 2 it is a diameter of：
d1=k1×dFC (4)
In formula (4), k1For silent partners diameter design coefficient, value 0.40；dFCFor steel wire rope composite fibre wire rope core diameter.
Four strands of Netted flap silent partners 2 of the utility model are primary using spinning and twisting loom with one sisal fiber core strand 1
Twisting is molded, and twirl method is ordinary lay.Wherein, the sisal fiber that core strand 1 is selected has excellent oil storage performance, what silent partners 2 was selected
Netted flap shock resistance is good, and compactness is high, and supportive is good, and oil storage is functional.
By the above-mentioned means, a kind of steel wire rope of the utility model with composite fibre wire rope core by sisal fiber item and netted poly- third
Alkene ribbon forms, and has excellent oil storage performance and shock resistance；The steel wire rope of the utility model composite fibre rope
Core primary twisting is molded, and wire rope core compactness is high, and diameter uniformity and support performance are good, its comprehensive performance is made obviously to be carried
It is high；The utility model is suitable for a variety of carrying shaped steel wire ropes, and level of application is wide；Most of all, the steel wire rope of the utility model
It is greatly improved with the composite fibre wire rope core service life, saves production cost.
