Abstract

The invention discloses a high-performance triangular-strand steel wire rope, which comprises six wire strands and a wire core. The six wire strands are uniformly twisted outside the wire core and arranged by forming 60-degree equant angles, and each wire strand is tangent with the wire core and is approximately triangular and comprises a strand core, three central steel wires, inner steel wires, middle steel wires and outer steel wires. The strand core is a circular steel wire strand formed by a plurality of steel wires, the three central steel wires are arranged on the periphery of the strand core by forming 120-degree equant angles and form a triangle shape with the strand core, the strand core and the central steel wires are wrapped by the inner steel wires, the middle steel wires are twisted on the outer periphery of the inner steel wires, and the outer steel wires are twisted on the outer periphery of the middle steel wires. Each strand core consists of forty six steel wires, and hardly any gaps are reserved among the inner steel wires, the strand core and the central steel wires. By twisting three times, the application range of the diameter of the steel wires and the range of the diameter of the steel wire rope can be maximized and flexibility of the steel wire rope is improved simultaneously.

Description

A kind of high-performance triangular strand wire rope

Technical field

The present invention relates to a kind of triangular strand wire rope, all good high-performance triangular strand wire ropes of particularly a kind of stability, antitorque commentaries on classics performance, pliability and reliability belong to the steel wire rope product technique field.

Background technology

Triangular strand wire rope is the mine special-purpose rope, is generally mine hoisting and uses steel wire rope, and construction project also can use, and belongs to the very large a kind of consumable material of use amount.In coal mining and heavy construction work progress, promote, directly influence operating efficiency and safety the service life of steel wire rope, the service life of ordinary steel rope is shorter, and mostly high performance steel wire rope is import, and cost is higher; Therefore, development high-performance triangular strand wire rope has very important significance.Existing triangular strand wire rope like accompanying drawing 3, shown in 4, comprises 6 strand 11, wire rope core 13; Said 6 rope strands 11 are twisted with the fingers the periphery built in wire rope core 13 uniformly; Per share rope strand 11 is all tangent with wire rope core 13; 6 rope strands 11 are according to the angle of 60 ° of five equilibriums; Said rope strand 11, the profile of said rope strand 11 is roughly triangular in shape; Comprise strand core 12, core wire 14, steel wire of internal layer 15, cover wire 16; The said strand of circular steel thread that core 12 is formed by many steel wires; Said core wire 14 has 3, is arranged on the arrangement of strand core 12 peripheries by 120 ° of five equilibriums, cooperates strand core 12 to form triangle; Said steel wire of internal layer 15 parcel strand core 12 and core wires 14; Said cover wire 16 is twisted with the fingers built in steel wire of internal layer 15 peripheries; Said steel wire of internal layer 15 be one group be arranged on strand core 12 and core wire 14 around, be triangle; Said cover wire is only tangent with core wire; Said cover wire is arranged on the periphery of steel wire of internal layer; The profile of said cover wire also is a triangle; Said steel wire of internal layer and cover wire group point-contact junction structure, the middle significantly space that exists; Cause in use, receive extruding, reverse or when crooked, the steel wire in the rope strand can move to void area, cause the steel wire rope unbalance stress and quick-fried disconnected phenomenon takes place, also produce dangerous reduction of service life; Simultaneously, said rope strand adopts secondary to twist with the fingers system, and promptly steel wire of internal layer and cover wire are twisted with the fingers system at twice, on the pliability of product and strand diameter, can't break through, and the application diameter range of steel wire and the diameter range of steel wire rope are limited, can only make the steel wire rope of minor diameter.

Summary of the invention

Technical problem to above-mentioned existence; The objective of the invention is: proposed a kind ofly can effectively solve the application diameter range of steel wire rope rope strand space, steel wire and the diameter range of steel wire rope; Improve product stability, antitorque commentaries on classics performance, pliability and reliability, lower-cost high-performance triangular strand wire rope.

Technical solution of the present invention is achieved in that a kind of high-performance triangular strand wire rope, comprises 6 strand, wire rope core; Said 6 rope strands are twisted with the fingers the periphery built in wire rope core uniformly; Per share rope strand is all tangent with wire rope core; 6 rope strands are according to the angle of 60 ° of five equilibriums; Said rope strand, the profile of said rope strand is roughly triangular in shape; Comprise a strand core, core wire, steel wire of internal layer, middle level steel wire, cover wire; The said strand of circular steel thread that core is formed by many steel wires; Said core wire has 3, is arranged on the arrangement of burst core periphery by 120 ° of five equilibriums, cooperates strand core to form triangle; Said steel wire of internal layer parcel strand core and core wire; Said middle level steel wire is twisted with the fingers built in steel wire of internal layer peripheral; Said cover wire is twisted with the fingers built in the middle level steel wire peripheral.

Preferably, said rope strand is made up of 46 steel wires; Internal layer adjacent steel wire, middle level steel wire, cover wire are the line contact.

Preferably, the profile of said steel wire of internal layer, middle level steel wire, cover wire is triangle.

Because the utilization of technique scheme, the present invention compared with prior art has advantage:

High-performance triangular strand wire rope of the present invention; Because the shape of rope strand is leg-of-mutton; Said high-performance triangular strand wire rope utilizes particular manufacturing craft and the equipment system of twisting with the fingers to form in process of production; And through rational wire distribution technology, per share rope strand is made up of 46 steel wires, between the steel wire of internal layer of rope strand and strand core and core wire, does not almost have the space to exist; And steel wire of internal layer, middle level steel wire, cover wire adopt twists with the fingers system three times, can make the range of application and the maximization of wirerope diameter scope of steel wire diameter, improves the pliability of steel wire rope simultaneously, to adapt to different use occasions; Thereby can prevent the problem of the shelling in the course of work, loose, antitorque commentaries on classics poor performance and pliability difference; The application diameter range of steel wire and the maximization of the diameter range of steel wire rope; And then can obtain the high stability of steel wire rope, high antitorque commentaries on classics performance, ideal flexible and high reliability; Improve product service life and enlarge the product range of application, reduce simultaneously and produce and use cost.
