Abstract

The invention belongs to the technical field of steel wire rope application and particularly provides a composite asphalt-dipped parallelly-entwisted dense steel wire rope. The composite asphalt-dipped parallelly-entwisted dense steel wire rope consists of a central strand, inner-layer strands arranged on the periphery of the central strand and arranged with the central strand in an enneagonal mode, outer-layer strands arranged on the peripheries of the inner-layer strands and arranged with the inner-layer strands in an enneagonal mode and a plastic coating layer uniformly coated on the surface of the central strand. The composite asphalt-dipped parallelly-entwisted dense steel wire rope has the advantages that the composite asphalt-dipped parallelly-entwisted dense steel wire rope is reasonable in structure, low in production cost, strong in tensile strength, fatigue resistance, corrosion resistance and abrasion resistance and long in service life, and the working efficiency and working safety of a vibration isolator device using the steel wire rope are effectively ensured; the high-strength and high-fatigue-resistance steel wire rope special for electrified railways is produced through repeated calculation, test, design and simulation test; compared with conventional steel wire rope, filling coefficients are high, contact layer steel wires are thickened, and accordingly the steel wire rope is high in strength, high in fatigue resistance and high in conductive performance.

Description

One kind is compound to leach the closely knit steel wire rope of blue or green parallel twisting

Technical field

The invention belongs to steel wire rope applied technical field leaches the closely knit steel wire of blue or green parallel twisting and in particular to one kind is compound Rope.

Background technology

With domestic and world's high-speed railway development, steel wire rope special for electrified railway consumption gets more and more, to its matter Amount and performance requirement more and more higher, it is mated to railway compensation device etc. is more also come more using the requirement of compound shaped steel wire rope Height is not it is considered on the premise of rope, the reasonable coordination of wheel and the increase less of single unit system race, compound wirerope diameter increases substantially Plus, higher requirement is proposed to the rupture pull force of compound shaped steel wire rope it is desirable to compound shaped steel wire rope has stronger resisting fatigue again While performance, fatigue performance, compound shaped steel wire rope also needs to there is preferable specific conductance, and existing compound shaped steel wire rope The design requirement of high-speed railway cannot be met, can not meet existing high standard alignment request.

Therefore, based on the problems referred to above, present invention offer one kind is compound to leach the closely knit steel wire rope of blue or green parallel twisting.

Content of the invention

Goal of the invention：It is an object of the invention to provide one kind is compound leaches the closely knit steel wire rope of blue or green parallel twisting, its structure letter Single, low production cost, has that stronger tensile strength, fatigue resistance, anticorrosive wear-resistant, and electric conductivity be excellent, service life Long, effectively ensure work efficiency and the job security of used steel rope fittings.

Technical scheme：Present invention offer one kind is compound to leach the closely knit steel wire rope of blue or green parallel twisting, by central strand, and is arranged on Central strand periphery and the internal layer stock with central strand arrangement in nonagon, and it is arranged on internal layer stock periphery and with internal layer stock in nonagon The outer layer strand of arrangement, and the coating layer composition on central strand surface for the even application；Described central strand is twisted by 16 galvanized wires；Institute State internal layer stock to be twisted by 4 galvanized wires；Described outer layer strand is twisted by 9 galvanized wires；Between described central strand, internal layer stock, internal layer Stock contacts with being between outer layer strand.

The technical program, described central strand is made up of four-layer structure, is followed successively by 1 plating of central strand central core from the inside to the outside Zinc wire, five galvanized wires of central strand internal layer, five galvanized wires of central strand packed layer, central strand outer layer is five galvanized wires；Described Internal layer stock is made up of four galvanized wires；Described outer layer strand is made up of double-layer structure, is followed successively by from the inside to the outside, outer layer strand internal layer one Galvanized wire, eight galvanized wires of outer layer strand outer layer.

The technical program, the central strand central core of described central strand, central strand outer layer, central strand internal layer, central strand are filled out The diameter filling layer successively decreases successively；Four zinc-plated linear diameters of described internal layer stock are identical；The outer layer strand internal layer of described outer layer strand straight Footpath is more than outer layer strand outer layer.

Compared with prior art, the present invention is a kind of compound leaches having the beneficial effects that of the closely knit steel wire rope of blue or green parallel twisting： 1st, its rational in infrastructure, low production cost, has stronger tensile strength, fatigue resistance, anticorrosive wear-resistant, and service life Long, effectively ensure to use the work efficiency of steel-wire isolator equipment and the safety of work；2nd, by calculating repeatedly, examination Test, design and simulation test, produce high intensity, high fatigue proof steel wire rope special for electrified railway, with conventional steel wires rope phase Higher than, activity coefficient, contact aspect steel wire overstriking, thus steel wire rope have high intensity, high endurance, high-conductivity excellent Point.

Brief description

Fig. 1 is that one kind of the present invention compound leaches blue or green parallel twisting closely knit construction of wire rope schematic diagram；

Wherein, in figure sequence number mark is as follows：1- central strand, 2- internal layer stock, 3- outer layer strand.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention.

Offer as shown in Figure 1 a kind of compound leaches the closely knit steel wire rope of blue or green parallel twisting, by central strand 1, and be arranged on Heart stock 1 periphery and with central strand 1 be in nonagon arrangement internal layer stock 3, and be arranged on internal layer stock 3 periphery and be in nine with internal layer stock 3 The outer layer strand 4 of side shape arrangement, and the coating layer 2 on central strand 1 surface for the even application forms；Central strand 1 is twisted with the fingers by 16 galvanized wires Become；Internal layer stock 3 is twisted by 4 galvanized wires；Outer layer strand 4 is twisted by 9 galvanized wires；Between central strand 1, internal layer stock 3, internal layer stock 3 It is between outer layer strand 4 and contact.

It is further preferred that central strand 1 is made up of four-layer structure, it is followed successively by central strand central core 1 from the inside to the outside zinc-plated Line, five galvanized wires of central strand internal layer, five galvanized wires of central strand packed layer, central strand outer layer is five galvanized wires；Internal layer stock 3 It is made up of four galvanized wires；Outer layer strand 4 is made up of double-layer structure, is followed successively by from the inside to the outside, piece galvanized wire of outer layer strand internal layer, outward Layer eight galvanized wire of stock outer layer；And the central strand central core of central strand 1, central strand outer layer, central strand internal layer, central strand packed layer Diameter successively decrease successively, four zinc-plated linear diameters of internal layer stock 3 are identical, the outer layer strand internal layer of outer layer strand 4 with diameter greater than outer layer Stock outer layer.
