Description
Technical field
The utility model relates to steel wire rope field, relates in particular to a kind of wire rope core.
Background technology
Wire rope core is the important component part of steel wire rope, mainly plays the effect of support and oil storage.Wire rope core is divided into the structures such as three core thighs, four-core thigh, eight core thighs by structure; By material, be divided into plant fiber core (as jute, sisal hemp, jute and sisal hemp mixed core), artificial fibre core (polyethylene, polypropylene, polyethylene and polypropylene mixed core) and metal-cored three kinds.In use, different wire rope core material bodies reveal different features: 1) plant fiber core oil content is good, and diameter uniformity is poor, value of thrust is low, hygroscopicity is strong, anti-extrusion ability; 2) acidproof, alkaline-resisting, the salt tolerant of artificial fibre core, diameter is more even, can bear larger pulling force, has good compressive property, and not mouldy, embrittlement not, but weak point is immersion oil ability can not be in excess Temperature and too low occasion work, easily aging.
Summary of the invention
The purpose of this utility model is to provide a kind of wire rope core, according to different purposes, in the situation that guaranteeing oil content, makes wire rope core have better anti-extrusion performance and stretching resistance, meets the chip-proof demand of steel wire rope product wire rope core under frequent impact condition.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A wire rope core, comprises strand, and described strand is three strands, and the laying pitch coefficient of strand is 9～9.5, and the laying pitch coefficient of wire rope core is 3～3.5, and the skin of described strand is artificial fibre core, and internal layer is plant fiber core.
Another kind of wire rope core, comprise strand, described strand is four strands, and the skin of described strand is artificial fibre core, and internal layer is plant fiber core, between four strands, be provided with center strand, the laying pitch coefficient of strand is 9～9.5, and the laying pitch coefficient of wire rope core is 3～3.5, and the laying pitch coefficient of center strand is 9～10, the skin of described center strand is artificial fibre core, and internal layer is plant fiber core.
Also has a kind of wire rope core, comprise strand, described strand is four strands, between four strands of strands, be provided with center strand, described strand is artificial fibre core, and center strand is plant fiber core, and the laying pitch coefficient of strand is 9～9.5, the laying pitch coefficient of wire rope core is 3～3.5, and the laying pitch coefficient of center strand is 9～10.
Compared with prior art, the beneficial effects of the utility model are:
Wire rope core oil content can be controlled at 25～30%, can meet product internal control index request, can make the shock resistance number of times of steel wire rope improve 15% simultaneously; Under the same terms, than sisal fiber wire rope core access times, improve 50%～60%.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
See Fig. 1, it is a kind of wire rope core embodiment mono-structural representation of the utility model, strand 1 is three strands, the laying pitch coefficient of strand is 9～9.5, the laying pitch coefficient of wire rope core in 3～3.5 scopes all can, the laying pitch coefficient of the preferred strand 1 of embodiment is 9.3, the laying pitch coefficient of wire rope core 2 is 3.2, the skin of strand 1 is artificial fibre core, and internal layer is plant fiber core.When the wire rope core of this structure is produced, by the plant fiber core band oil of wire rope core inside, realized.
See Fig. 2, a kind of wire rope core embodiment bis-structural representations of the utility model, strand 1 is four strands, the skin of strand is artificial fibre core, internal layer is plant fiber core, between four strands, be provided with center strand 3, the laying pitch coefficient of strand is 9～9.5, the laying pitch coefficient of wire rope core is 3～3.5, the laying pitch coefficient of center strand in 9～10 scopes all can, the laying pitch coefficient of the preferred strand 1 of embodiment is 9.3, the laying pitch coefficient of wire rope core 2 is 3.2, the laying pitch coefficient of center strand 3 is 9.5, and the skin of center strand 3 is artificial fibre core, and internal layer is plant fiber core.When the wire rope core of this structure is produced, by the plant fiber core band oil of wire rope core inside, realized.
See Fig. 3, a kind of wire rope core embodiment tri-structural representations of the utility model, strand 1 is four strands, between four strands of strands, be provided with center strand 3, strand 1 is all artificial fibre core, center strand 3 is all plant fiber core, the laying pitch coefficient of strand is 9～9.5, the laying pitch coefficient of wire rope core is 3～3.5, the laying pitch coefficient of center strand all can in 9～10 scopes, the laying pitch coefficient of the preferred strand 1 of embodiment is 9.3, and the laying pitch coefficient of wire rope core 2 is 3.2, and the laying pitch coefficient of center strand 3 is 10.When the wire rope core of this structure is produced, by the center strand 3 band oil of wire rope core 1 inside, realized.
In above-described embodiment, artificial fibre core can be selected stripping fiber or the slice fiber of polyethylene, polypropylene, polyethylene and polypropylene blending.Plant fiber core can be selected jute or sisal core.Artificial fibre core can be given full play to its anti-extrusion performance in the periphery of wire rope core, reduces the squeezed broken possibility of surface fiber.
Because the fusing point of artificial fibre core is lower, therefore the utility model is produced in the mode of plant fiber core band oil, when strand is produced, while first plant fiber core being pressed in to oil groove, through slightly smearing after wiping away, be twisted in strand, thereby make strand band oil, consider shock-resistant, antifatigue, the requirement that structural behaviour is good, laying pitch coefficient is chosen by 9～9.5 of diameter.
