Abstract

The utility model relates to a new GS8T31 steel wire rope with a surface contact structure, which is twisted by a metal rope core (1) and eight outer strands 1T*31SW (2) in one time, the metal rope core in the steel wire is formed by a 1*7, 1*25Fi, 1*26SW point contact or line contact structure metal strand core (3), a plurality of 1*26 SW line contact or surface contact structure outer big strands (4) and a plurality of 1*3, 1*7 point contact structure outer filling small strands (5). The steel wire rope has merits of long service life, strong bearing capability, high endurance bending strength, good plasticity and anti wear property, and good shock resistance and destruction resistance capability, can used in all kinds of hoisting machinery and bridge crane in steel factory, can improve the service life, reduce product cost and enhance product efficiency.

Description

A kind of surface contact structure steel wire rope

One, technical field

The utility model belongs to the metallic article technical field, especially belongs to a kind of GS8T31 surface contact structure steel wire rope.

Two, background technology

Existing metal core steel wire rope, the wire rope core structure is made of a thigh core and outer six roots of sensation strand usually, steel wire rope is easy to generate wire rope core and exposes with wire rope core early fracture, outer layer strand and play steel cord structure destructions such as lantern in installing and using, steel wire rope can not normally use, and economic loss is bigger.And the steel wire rope bearing capacity is less relatively, and counter-bending fatigue behaviour is low, and abrasion resistance properties is poor, use on various hoisting machineries and steel plant's overhead crane, steel wire rope is lower service life, causes steel rope replacing frequent, increase production cost, had a strong impact on production.Yet there are no GS8T31 surface contact structure steel wire rope in the market.

Three, summary of the invention

The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of surface contact structure steel wire rope is provided, make its metal filled coefficient and the rupture pull force coefficient is big, bearing capacity is big, counter-bending fatigue behaviour height, softness and abrasion resistance properties are good, improve service life simultaneously, reduce production costs, enhance productivity.

The metal core of surface contact structure steel wire rope of the present utility model, owing to have special structural design, firm in structure, to the strain that produces owing to reel system, winding position is improper, and the installation of steel wire rope is improper or in adverse circumstances use etc., and is very little to the influence of steel wire rope.It can good absorption from the strength of outside, have good shock resistance, survivability.

A kind of surface contact structure steel wire rope described in the utility model, the GS8T31 structure is 8T * 31SW+IWR, steel wire rope is formed by a metal core and eight outer steel cable thigh 1T * 31SW primary twistings.

The metal core structure is 6 * 7 (F)+6 * 26SW+IWS, by a central strand core, the outer shallow bid twisting of filling of many (being four, six or eight) outer big thigh and many (being four, six or eight) forms, the central strand core is 1 * 7, some contact or line contact structures such as 1 * 25Fi, 1 * 26SW, is formed by 7,25 or 26 steel wire primary twistings respectively; Outer big strand is contact of Xi Washi line or surface contact structure, and every thigh is formed by 26 steel wire primary twistings; Outer filling shallow bid is the point-contact junction structure, and every thigh is formed by 7 or 3 steel wire primary twistings.Eight outer layer strand 1T * 31SW structures are the Xi Washi surface contact structure, and every thigh is formed by 31 steel wire primary twistings.

Adopt the beneficial effect of such scheme to be:

1, the metal core outer surface is full in the steel wire rope, and level and smooth, steel cord structure is tight;

2, metal filled coefficient of steel wire rope and rupture pull force coefficient are big, and bearing capacity is big;

3, the bent fatigue behaviour height of rope anti-bend, softness and abrasion resistance properties are good;

4, steel wire rope long service life;

5, steel wire rope shock resistance, survivability are strong;

6, reduce production costs, enhance productivity.

Four, description of drawings

Accompanying drawing 1 is a kind of surface contact structure steel wire rope cross section structure schematic diagram.

Among Fig. 1: 1-metal core, the outer steel cable thigh of 2-, 3-metal core central strand core, outer big strand of 4-metal core, the outer shallow bid of filling of 5-metal core.

Five, the specific embodiment

The utility model is a kind of surface contact structure steel wire rope GS8T31, and specific embodiment contrast accompanying drawing is described further, and its structure is formed by a metal core (1) and eight outer steel cable thighs (2) primary twisting.But change the wherein steel wire rope of steel wire diameter twisting different-diameter.

A kind of surface contact structure steel wire rope GS8T31 is by a central metal wire rope core (1) and eight isostructures, constitute with the outer steel cable thigh of diameter (2); Wherein eight outer layer strand (2) are 1T * 31SW surface contact structure, and metal core in the steel wire rope (1) is by a metal thigh core (3), and many skins big strand (4) and the many outer shallow bids (5) of filling constitute; In the metal core (1), metal thigh core (3) structure is 1 * 7, the contact of 1 * 25Fi, 1 * 26SW point or line contact structures; Many skins big strand (4) and the many outer shallow bids (5) of filling are four, six or eight in the metal core (1); Many skins big strand (4) are contact of 1 * 26SW line or surface contact structure in the metal core (1); Many outer filling shallow bids (5) are 1 * 3,1 * 7 point-contact junction structure in the metal core (1).
