Abstract

Disclosed is a whole-strand contact-compacting steel cable commonly used in the fields of the industry, the building industries, etc, comprising an outer strand 1, core strands 2, 3, an outer strand steel cable 4, and an outer envelope 5. A core cable is twisted with a main cable in equal distance at one time, and the outer strand 1 is positioned in the valley part between the core strand 2 and the core strand 3. The outer strand steel cable 4 of the steel cable is exposed on the surface 4.1 outside the cable body and is tangential to the outer envelope 5 of the whole cable. The inner part or the whole steel cable 8 whose strands are provided with gaps 9 is polygon-shaped. With the characteristics of large breaking force, good wear resistance, decreased elongation, long service life, etc, the steel cable is the non-loosing steel cable.

Description

A kind of all fronts contact compacting steel wire rope

Relate to the field

The utility model belongs to the steel wire rope that generally use in fields such as industry, building industry, particularly a kind of all fronts contact compacting steel wire rope.

Background technology

The structure of steel pole steel wire rope of present domestic production, no matter whether the core rope adopts the equal lay twisting with main rope, and the group rope strand is carried on as before and is so kept circle burst feature, so this structure steel wire rope still belongs to round-strand rope.The rupture pull force that can't obviously improve steel wire rope with increase steel wire rope in use with the contact area of coupling race.

Technology contents

The utility model purpose is to provide a kind of rupture pull force that can obviously improve steel wire rope in use to contact the compacting steel wire rope with all fronts of the contact area of mating race with the increase steel wire rope.

The utility model is achieved in that and comprises silent partners 1, core rope strand 2,3, silent partners steel wire 4, external envelope face 5, core rope and main rope equal lay primary twisting, silent partners 1 is in the paddy portion between the core rope strand 2,3, it is tangent with the external envelope face 5 of whole rope that steel wire rope silent partners steel wire 4 is exposed to the external surface of rope 4.1, the part or all of steel wire 8 of internal layer is a polygon, between its silk and the silk space 9 is arranged, there is the deformation surface 10 through overcompaction on the surface of every steel wire outside whole steel wire rope is exposed to.

The utility model also adopts following technical scheme:

It is tangent with the external envelope face 5 of whole rope that steel wire rope silent partners steel wire 4 is exposed to the external surface of rope 4.1, and radius of curvature is identical, and steel wire section or circle lack, perhaps half garden, perhaps more than half garden.

6 places, slit 7 place's adjacent wires are line contact, face contact respectively in the slit;

Abnormity (non-circular) feature appears in group rope silent partners;

Advantage of the present utility model is:

1. steel wire rope is organized strand steel wire and is line contact the becoming compound contact of line-face by original single behind overcompaction.Because of increasing compact stress, contact area reduces between the steel wire.The relative position of steel wire is more stable in strand.The use elongation reduces.

Steel wire rope behind overcompaction, not only make former close in the rope twisting process burst inhomogeneous defective of tension force be improved significantly, and make and close the rope residual stress and obtain further fully eliminating earlier.

3. steel wire rope metal filled coefficient behind overcompaction obviously increases, and compares with isostructure, diameter ordinary steel cored structure steel wire rope, and effective bearing area, breaking force of rope obtain raising by a relatively large margin.

Steel wire rope behind overcompaction not only silent partners obviously abnormity burst feature appears, and a main strand outer surface becomes cylinder, surface smoothing makes steel wire rope in use with the coupling race bigger contact area be arranged, the steel wire rope ABRASION RESISTANCE obviously improves.

Contact completely the compacting steel wire rope have that rupture pull force is big, ABRASION RESISTANCE is excellent, elongation reduces with long service life etc. characteristics.This steel wire rope is a preformed wire rope.

Fig. 2 is an external structure schematic diagram of the present utility model.

Concrete enforcement

As shown in Figure 1 and Figure 2, core rope and main rope equal lay primary twisting, silent partners 1 is in the paddy portion between the core rope strand 2,3; It is tangent with the external envelope face 5 of whole rope that steel wire rope silent partners steel wire 4 is exposed to the external surface of rope 4.1, and radius of curvature is identical, and steel wire section approximate circle lacks, half garden, more than half garden, at 6 places, 7 place's adjacent wires are line contact, face contact respectively; The part or all of steel wire 8 of internal layer is a polygon; Space 9 is little between silk and the silk; Abnormity (non-circular) feature appears in group rope silent partners; There is the deformation surface 10 through overcompaction on the surface of every steel wire outside whole steel wire rope is exposed to.

Contacting the compacting wire rope core completely is and main the metal-cored of equal lay of restricting.

Contacting compacting steel wire rope rope silent partners structure completely is the line contact.

Contact compacting wire rope core and main rope equal lay primary twisting completely.

Contacting the compacting steel wire rope completely is multiply.
