Abstract

The utility model discloses a cable type wire rope which is formed by six or eight multistrand wire ropes entwisted around a rope core; the rope core is a fiber core or a wire rope core; and each multistrand wire rope is formed by six or eight identical outer strands and a rope core. The cable type wire rope has good flexibility and big breaking force, the diameter of the cable type wire rope can reach above 200mm, and the breaking force of the cable type wire rope can reach above 10,000kN. Therefore, the cable type wire rope can satisfy the requirement on large bearing capacity of a large hoisting rigging in oceanographic engineering.

Description

A kind of cable lay wire rope

Technical field

The utility model relates to a kind of cable lay wire rope, belongs to the metallic article technical field.

Background technology

Existing steel wire rope divides by the twisting type and mainly contains single twist composite steel rope and two twist composite steel ropes, and single twist composite steel rope is that primary twisting is finished, and core wire is linear state, and cover wire is a helical form, such as single cord; Two twist composite steel ropes will form by twice twisting, are formed around a fibre core or steel core twisting by many steel strands, and each strand core wire is a helical form, and all the other steel wires are the secondary spiral shape.The problem that existing steel wire rope exists is, the steel wire rope flexibility is relatively poor, rupture pull force is little, the steel wire rope specification is little, wirerope diameter is generally less than 120mm, rupture pull force does not reach 10000kN, can not satisfy ocean engineering, Large-scale Hoisting rigging to the demand of the above large-specification wire rope of diameter 200mm and the above high bearing capacity of rupture pull force 10000kN.

The utility model content

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of cable lay wire rope is provided, to improve the steel wire rope softness, improve breaking force of rope, satisfy ocean engineering, Large-scale Hoisting rigging to the demand of the above large-specification wire rope product of diameter 200mm high bearing capacity.

The utility model is the steel tendon that is formed around fibre core or Steel cord twisting by many multistrand ropes, to form through three twistings, also be cable-laid rope, each strand of steel wire rope core wire is the secondary spiral shape, all the other each layer steel wires are helical form three times, this steel wire rope is under the diameter same case, and better than the softness of ordinary steel rope, rupture pull force is larger.

The utility model is formed around a wire rope core twisting by the six roots of sensation or eight multistrand ropes, wire rope core is fibre core or Steel cord, steel cord structure is made of the six roots of sensation or eight identical silent partners and wire rope core, silent partners is some contact, line contact or dotted line contact structures, formed by 31～111 steel wire twistings, structure is 1 * 37 or 1 * 61 or 1 * 31WS or 1 * 41WS or 1 * 49SWS or 1 * 55SWS or 1 * 64SFS or 1 * 80WSNS.

But change the cable lay wire rope of the diameter twisting different-diameter of multistrand rope in a kind of cable lay wire rope of the utility model.

The beneficial effects of the utility model:

1, compare with the steel wire rope with diameter, the steel wire radical is many, diameter is little, and steel wire rope toughness is better.

2, increase wirerope diameter, improved greatly the bearing capacity of steel wire rope.

Description of drawings

Fig. 1 is a kind of cable lay wire rope cross section structure of the utility model schematic diagram.

Among the figure: 1-wire rope core, 2-steel wire rope.

The specific embodiment

Below in conjunction with accompanying drawing a kind of cable lay wire rope of the utility model is described in further detail:

Among the figure, it is made of around wire rope core 1 twisting the six roots of sensation or eight multistrand ropes 2.

Described wire rope core 1 is fibre core or Steel cord.

Described steel wire rope 2 structures are made of the six roots of sensation or eight identical silent partners and wire rope core, silent partners is some contact, line contact or dotted line contact structures, formed by 31～111 steel wire twistings, structure is 1 * 37 or 1 * 61 or 1 * 31WS or 1 * 41WS or 1 * 49SWS or 1 * 55SWS or 1 * 64SFS or 1 * 80WSNS.

But change the cable lay wire rope of the diameter twisting different-diameter of multistrand rope 2 in a kind of cable lay wire rope of the utility model.
