Abstract

A high-strength abrasion-resistant steel wire rope for lifting is composed of a central rope, an inner-layer rope and an outer-layer rope. Excavators, large-scale casting and busy hoisting and lifting have high requirements on used steel wire ropes, while existing steel wire ropes used the most frequently all have limits in performance and characteristics, some are high in abrasion resistance but rigid, some are soft but not abrasion-resistant, and some are abrasion-resistant and soft but poor in rotating performance. The high-strength abrasion-resistant steel wire rope for lifting is composed of the central rope, the inner-layer rope and the outer-layer rope which are all processed by compaction technology. The outer-layer rope is in the warrington structure, and secondary entwisting is adopted during rope combining, thereby enabling the steel wire rope to be high in breaking force, strong in abrasion resistance, good in softness and low in rotating performance.

Description

A kind of high-strength abrasion-proof promotes uses steel wire rope

Technical field

The utility model relates to a kind of rope, especially metallic cable.

Background technology

Use maximum steel cord structures that 6 * 19S, 6 * 19W, 6 * 29F, 6 * 31WS etc. are arranged at present; The steel wire rope performance characteristics of these structures all has limitation, the not only wear-resisting but also softness that the rope that the ABRASION RESISTANCE that has is strong but steel wire rope hard, have is soft but not wear-resisting, have but verticity is poor.The utility model has well solved above problem, adopts 11 steel strand secondaries sth. made by twisting systems and mold cold drawing process technology to combine, and can guarantee to reach high strength, high-wearing feature, good flexibility, low rotatory with the steel wire rope under the diameter.

The utility model content

The purpose of the utility model in order to solve the problem that above-mentioned prior art exists, provides the wear-resisting lifting of a kind of novel high-strength to use steel wire rope exactly.

Wa Lin gulps down the formula structure: expression strand wire ectomesoderm steel wire diameter does not wait, the thicker steel wire of preparation between the groove of two steel wires of adjacent inner layer, and at the thinner steel wire of the top of steel wire of internal layer configuration, this steel wire rope is with letter " W " expression " Wa Lin gulps down ".

1 * K7: 1 thigh of 1 expression, K representes the method that the compacting thigh is represented in the steel wire rope industry standard, in 1 thigh of 7 expressions 7 steel wires are arranged.

1 * K19W: 1 thigh of 1 expression, K representes the method that the compacting thigh is represented in the steel wire rope industry standard, in 1 thigh of 19 expressions 19 steel wires are arranged, and divides two layers (1-6-6+6) " W " expression " Wa Lin gulps down ".

Adopt mold cold drawing process technology when steel wire is twisted with the fingers system: expression adopt when twisting with the fingers burst sintered carbide die give certain pulling force steel wire from rough to carefully, this process just need not heat and can accomplish, so in our industry, be called cold-drawing process.

6 * 19S, 6 * 19W, 6 * 29F, 6 * 31WS: all be the version among the steel wire rope standard GB8918-2006.

5 * K19W-IWRC (K)-1960-￠ 16mm: 5 expression steel wire ropes have 5 thighs, and K representes the compacting thigh, and 19 expressions each strand have 19 steel wires, W to represent that a watt woods gulps down structure, IWRC (K) represent steel wire rope metal-cored be compacting thigh core.

￠: strand diameter

In order to achieve the above object, the utility model adopts following technical scheme:

A kind of high-strength abrasion-proof promotes uses steel wire rope; Form by central strand, internal layer thigh and outer layer strand; Said central strand is made up of 11 * K7 compacting thigh; Said internal layer thigh is made up of 51 * K7 compacting thighs around being evenly distributed on central strand, and said outer layer strand is made up of 51 * K19W steel wire ropes around being evenly distributed on the internal layer thigh.

As preferably, said central strand and internal layer thigh are formed by 7 steel wires, and 1 steel wire is positioned at the center, and all the other 6 are evenly distributed on around it, and the contact condition of each steel wire is a face contact shape.

As preferably, said outer layer strand adopts 1 * K19W watt of woods to gulp down the formula structure, is made up of 19 steel wires, and the center is 1 steel wire, and it is outer to be that 6 steel wires are uniformly distributed with the composition internal layer, and 12 steel wires in the internal layer outside are uniformly distributed with to be formed outerly, and the contact condition of each steel wire is that face contacts shape.

The utility model makes it compared with prior art owing to adopted above technical scheme, has the following advantages and characteristics:

1. adopt mold cold drawing process technology, make that the contact condition between each steel wire becomes face contact shape by line contact shape in the thigh, when having stablized structure of steel wire, increased the effective metal area of steel wire rope again.

2. adopt the secondary system of twisting with the fingers to form when closing rope, for the some contact condition, increase the flexibility of steel wire rope between internal layer thigh and the outer layer strand, thereby make steel wire rope in use be convenient to twine, improve the steel wire rope fatigability.

3. the steel wire rope outer layer strand adopts a watt woods to gulp down the formula structure and uses mold cold drawing process technology, has increased the ABRASION RESISTANCE and the flexibility of steel wire rope.

4, ABRASION RESISTANCE is strong, flexibility good, the big performance of load-carrying ability is strong, and the rupture pull force coefficient is high, and at present common 6 * 19 (a) types linear contact lay wire rope national standard rupture pull force coefficient is 0.356, this steel wire rope reach 0.41, improved about 15%.
