Abstract
A nylon strand core steel wire rope comprises eight outer layer strands and a metal core. The outer layer strands are annularly arranged on the periphery of the metal core, every outer layer strand is respectively composed of 9-15 steel wires and a PPC nylon core having high pressure resistance, the metal core is composed of a metal core outer layer and a metal core center strand, the metal core outer layer comprises four metal core main strands and four filling strands, and the metal core main strands and the filling strands are arranged at intervals. The nylon strand core steel wire rope is extremely good in softness and suitable for occasions with complex pulley systems; due to the fact that the every outer layer strand structure of the steel wire rope is formed by the 9-15 steel wires and the PPC nylon core having high pressure resistance by twisting, the steel wire rope is extremely good in stability, large in metal filling area and high in braking force, diameter changes are small when the steel wire rope is in use, and the steel wire rope can be used in special industries such as elevators without needing pretension treatment.
Description
Technical field
The present invention relates to a kind of steel wire rope, be a kind of nylon thigh independent wire strand core wire rope with being specifically related to.
Background technology
Steel wire rope technology has a great development in recent years, and the steel wire rope of simultaneously various lifting means being used requires also to come higher, especially the stability of steel wire rope and equipment, security is had higher requirement.The steel wire rope of as metal-cored in 8*19+, the fibre core of tradition steel wire rope, hemp core can not be applicable to the requirement of the lifting means such as crane elevator.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind of nylon thigh independent wire strand core wire rope.
Technical solution of the present invention is achieved in that a kind of nylon thigh independent wire strand core wire rope, comprise 8 outer layer strand and 1 metal-cored, described outer layer strand annular array is in metal-cored periphery; Wherein each outer layer strand is comprised of the steel wire of 9 to 15 and the PPC nylon core with high withstand voltage properties respectively again, and metal-coredly metal-cored skin and metal-cored central strand, consists of; Described metal-cored skin includes 4 metal-cored main thighs and 4 fillings strand, and interval setting between described metal-cored main thigh and filling thigh.
Further, the diameter of described metal-cored main strand is greater than the diameter of filling thigh, and each filling strand contacts with two that are adjacent metal-cored main strands respectively again.
Further, described metal-cored central strand is comprised of 7 steel wires.
Further, described metal-cored main strand is also comprised of 7 steel wires.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Nylon thigh independent wire strand core wire rope described in the present invention program has extraordinary flexibility, is adapted at using in the occasion of complicated pulley system; The PPC nylon core twisting that adopts the steel wire of 9 to 15 and have a high withstand voltage properties due to the outer layer strand structure of this steel wire rope forms, it has good stability, metal filled area is large, there is high Fracture Force, and diameter variation is little in use for it, stretch-draw is processed and also can be met in the special industries such as elevator and use in advance; Adopt the withstand voltage PPC nylon core of high strength simultaneously, can increase its deformability, when it is applied on pulley groove, its steel wire rope is accepted more even, operates steadily, and then has extended its service life; And the grease that the withstand voltage PPC nylon core of high strength contains can make its lubricant effect retain the longer time, reduced the wearing and tearing of steel wire rope, increased its fatigue performance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of nylon thigh independent wire strand core wire rope of the present invention;
Wherein: 1, outer layer strand; 2, metal-cored; 3, PPC nylon core; 4, metal-cored skin; 5, metal-cored central strand; 6, metal-cored main strand; 7, fill thigh.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Accompanying drawing 1 is nylon thigh independent wire strand core wire rope of the present invention, comprise 8 outer layer strand 1 and 1 metal-cored 2, described outer layer strand 1 annular array is in metal-cored 2 periphery; Wherein each outer layer strand 1 is comprised of the steel wire of 9 to 15 and the PPC nylon core 3 with high withstand voltage properties respectively again, and metal-cored 2 by metal-cored outer 4 and metal-cored central strand 5 form; Described metal-cored outer 4 include 46 and 4, metal-cored main thighs fills thigh 7, and between described metal-cored main thigh 6 and filling thigh 7, interval arranges.
The diameter of wherein said metal-cored main strand 6 is greater than the diameter of filling thigh 7, and each filling thigh 7 contacts with two that are adjacent metal-cored main strand of 6 lines respectively again; And described metal-cored central strand 5 is the same with metal-cored main thigh 6, all by 7 steel wires, formed.
The profile of the rope strand 1 of triangular strand wire rope of the present invention is approximate equilateral triangle, and mends rib silk 4 form the shape of triangle together with thigh core 3, and cover wire 6 is owing to being arranged on the periphery of steel wire of internal layer 5, and its profile is also triangle.
Nylon thigh independent wire strand core wire rope described in the invention has extraordinary flexibility, is particularly suitable for using in the occasion that has complicated pulley system; This steel wire rope percentage elongation is low, under the same conditions, because adopting the steel wire of 9 to 15, this structure nylon thigh independent wire strand core wire rope outer layer strand 1 forms with PPC nylon core 3 twistings with high withstand voltage properties, its structure is more stable, metal filled area is larger, there is higher Fracture Force, and its permanent elongation is only 0.1% of original steel wire rope, thus its percentage elongation be only in prior art hemp center wireline 1/6.The diameter of this steel wire rope changes little, this steel cord structure metal-cored 2 by metal-cored outer 4 and metal-cored central strand 5 form; Described metal-cored outer 4 include 4 metal-cored main strand 6 and 4 fills thigh 7, and between described metal-cored main thigh 6 and filling thigh 7, interval arranges, this special design, make this steel wire rope there is good stability, rupture pull force is large, diameter changes little, and stretch-draw is processed and also can be met in the special industries such as elevator and apply in advance.Outer layer strand 1 due to this steel wire rope has adopted the withstand voltage PPC nylon core 3 of high strength simultaneously, it can increase the deformability of this steel wire rope, when it is applied on pulley groove, can increase the contact area of this steel wire rope and pulley groove, make steel wire rope stressed more even, operate steadily, and then extended the use longevity of this steel wire rope; And the grease that this PPC nylon core 3 with high withstand voltage properties contains can make its lubricant effect retain the longer time, reduced the wearing and tearing of steel wire rope, increased its fatigue performance.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
