Abstract

The utility model discloses a steel wire rope for a rotary digging machine, which is an all-compaction strands steel wire rope made by using three layers of strands to wrap and twist a central strand; each strand is formed by using six outer-layer steel wires to wrap and twist a central steel wire; the shape of the outer-layer steel wire is similar to a trapezoid; the shape of the central steel wire is similar to a regular hexagon; the steel wire and the steel wire in the strands are in a surface-contact shape, wherein the twisting direction of the outer-layer strand is opposite to that of the two inner-layer strands, and the interior of the steel wire rope is filled with grease. The steel wire rope for the rotary digging machine respectively improves wear resistance, fatigue resistance, rotation resistance and the tension force of the whole rope obviously compared with the prior art.

Description

A kind of Spiral digging machine steel wire rope

Technical field

The utility model relates to a kind of steel wire rope, particularly, relates to a kind of Spiral digging machine steel wire rope.

Background technology

The working environment of Spiral digging machine is very abominable, and is therefore high especially to requirements of Wire Rope.Present Spiral digging machine steel wire rope, as 35W * 7 serial steel wire ropes etc., its rupture pull force is not high, and in use with the contact time of elevator, pulley long after very easily wearing and tearing, reduce service life greatly.

The utility model content

The purpose of this utility model is at above-mentioned defective of the prior art, proposes a kind of rupture pull force and anti-wear performance Spiral digging machine steel wire rope preferably.

The technical scheme that realizes above-mentioned purpose is as follows:

A kind of Spiral digging machine steel wire rope is to twist with the fingers the total head real shares steel wire rope that the central strand twisting forms by three layers of thigh bag, is face between steel wire and steel wire in described strand and contacts shape.

Further, the sth. made by twisting of the outer layer strand of described steel wire rope to interior two-layer strand sth. made by twisting to opposite.

Further, described steel wire rope inside is full of grease.

Further, per sharely in the described steel wire rope all twist with the fingers a core wire and form by 6 cover wire bags, described cover wire approximate trapezoid, described core wire is similar to regular hexagon.

Further, described steel wire rope be by 35 personal shares be the half-watt woods gulp down the formula structure at twice twisting form.

Further, described steel wire rope is the light face, and nominal diameter is 28mm, and nominal tensile strength is 1960Mpa.

The utlity model has following beneficial effect:

1, the mode of production of utilizing die drawing is carried out (cold-)drawn (steel)wire rope rope strand with mould when twisting with the fingers burst, and wire shape in changing strand but do not change the cross-sectional area of steel wire substantially makes to be face between steel wire and steel wire in the rope strand and to contact shape, then closes rope again.Because the structure of rope strand is face contact shape through the mould extruding, has improved steel wire rope metal effective area, breaking force of rope has improved more than 14%, and the contact-making surface with elevator, pulley is big in use, and ABRASION RESISTANCE improves.

2, the steel wire rope of this kind structure is twisted with the fingers a central strand twisting by three layers of thigh bag and is formed, the sth. made by twisting of outer layer strand to interior two-layer strand sth. made by twisting to opposite, its resistance rotation performance is good.

3, simultaneously, adopt the go further mode of oil cauldron of a burst oil spout, steel wire rope when producing this rope, steel wire rope inside also is full of grease, and the oil content of whole piece rope improves, and has further improved the anti-fatigue performance of steel wire rope, has satisfied the Spiral digging machine requirements of Wire Rope.

4, in use, steel wire rope of the present utility model has stronger ABRASION RESISTANCE, crush resistance and resistance to shock loads performance, and can improve more than 20% service life.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Description of drawings

Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the cross-sectional structure schematic diagram of a kind of Spiral digging machine of the utility model with steel wire rope.

In conjunction with the accompanying drawings, Reference numeral is as follows among the utility model embodiment:

The 1-core wire; The 2-cover wire.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, a kind of Spiral digging machine steel wire rope of the present utility model, specifications and models are 28NATDL1916AK 1960, be to twist with the fingers the total head real shares steel wire rope that the central strand twisting forms by three layers of thigh bag, wherein the sth. made by twisting of outer layer strand to interior two-layer strand sth. made by twisting to opposite, per sharely all twist with the fingers a core wire 1 and form, wherein cover wire 2 approximate trapezoid by 6 cover wires, 2 bags, the approximate regular hexagon of core wire 1 is face between steel wire and steel wire in strand and contacts shape.The said structure steel wire rope by 35 personal shares be the half-watt woods gulp down the formula structure at twice twisting form.Steel wire rope is the light face, and nominal diameter is 28mm, and nominal tensile strength is 1960Mpa.

Spiral digging machine steel wire rope of the present utility model is to utilize the mode of production of die drawing to carry out (cold-)drawn (steel)wire rope rope strand with mould when twisting with the fingers thigh, wire shape in changing strand but do not change the cross-sectional area of steel wire substantially, make to be face between steel wire and steel wire in the rope strand and to contact shape, then close rope again.

Simultaneously, adopt the go further mode of oil cauldron of a burst oil spout, steel wire rope when producing this rope, steel wire rope inside also is full of grease, and the oil content of whole piece rope improves, and has further improved the anti-fatigue performance of steel wire rope, has satisfied the Spiral digging machine requirements of Wire Rope.

It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
