Abstract
The invention discloses a steel wire rope for a rotary drilling machine and a preparation method thereof. The steel wire rope is a fully pressed solid-strand steel wire rope by twisting three layers of strands around a central strand; each strand is formed by twisting 6 outer-layer steel wires around a central steel wire; the steel wires on the outer layer are approximately trapezoid; the central steel wire is approximately hexagonal; and steel wires in the strands are in surface contact with the steel wires, wherein the twist direction of strands of the steel wire rope on the outer layer is opposite to the twist direction of strands on two inner layers, and oil is filled in the steel wire rope. In the preparation method of the steel wire rope for the rotary drilling machine of the invention, cold drawing is performed on steel wire rope strands by using a die when the strands are twisted by utilizing a production mode of die drawing, the shape of the steel wires in the strands is changed but the cross section area of the steel wires is basically not changed to ensure that the steel wires in the rope strands are in surface contact with the steel wires, and stranding is performed; and simultaneously a mode of spraying oil on the strands and allowing the steel wire rope to pass through an oil pan is adopted during the production. Compared with those of the prior art, the wear resistance, the fatigue resistance, the rotation resistance and the entire tensile force of the steel wire rope for the rotary drilling machine are all remarkably improved.
Description
Technical field
The present invention relates to a kind of steel wire rope, particularly, relate to a kind of Spiral digging machine steel wire rope and preparation method thereof.
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.
Summary of the invention
An object of the present invention is at above-mentioned defective of the prior art, propose a kind of rupture pull force and anti-wear performance Spiral digging machine steel wire rope preferably.
Another object of the present invention provides the preparation method of a kind of above-mentioned Spiral digging machine with steel wire rope.
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.
Above-mentioned Spiral digging machine utilizes 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 with the preparation method of steel wire rope, 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.
Further, when producing, adopt a burst oil spout, the go further mode of oil cauldron of steel wire rope.
The present invention 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 invention 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, technical scheme of the present invention is described in further detail.
Description of drawings
