Abstract

The invention relates to a steel wire rope used for a port. The steel wire rope comprises an inner layer and an outer layer. The inner layer is formed by six inner layer strands. The outer layer is formed by six outer layer strands. The steel wire rope also comprises a central strand. The six inner layer strands are uniformly wrapped on the periphery of the central strand. The inner layer strands and the central strand contact by surface. The outer layer strand uses a Seal-Warrington-Seal composite structure. The steel wire rope used for a port is formed by a plurality of layers of multi-wire strands. The central strand and the inner layer strands are in few-wire line contact structure. The steel wire rope is simple and convenient in manufacturing process, and soft performance of the steel wire rope is ensured. The outer layer strands uses the Seal-Warrington-Seal composite structure, and point, line, and surface contact is created in a same strand, thereby ensuring abrasive resistance and soft property of the steel wire rope. Through the Seal-Warrington-Seal rational steel wire combination, comprehensive performance of the steel wire rope is improved, and load of the steel wire rope is large, and service life of the steel wire rope is prolonged.

Detailed description of the invention

Technical solution of the present invention is introduced in detail below in conjunction with accompanying drawing.

As shown in Figure 1, the harbour steel wire rope of soft wear resistant, comprise central strand 1, internal layer stock 2, outer layer strand 3, each layer stock carries out helical form bag sth. made by twisting round central strand 1, in linear contact lay shape, symmetry bag sth. made by twisting central strand 1 forms metal core to 6 internal layer stocks 2, and 6 outer layer strand 3 twist with the fingers metal core symmetrically, in point cantact shape bag.

Wherein, central strand 1 comprises 6 cover wires 12 of a core wire 11 and linear contact lay bag sth. made by twisting core wire 11, internal layer stock 2 comprises 6 cover wires 22 of a core wire 21 and linear contact lay bag sth. made by twisting core wire 21, forms between steel wire in linear contact lay shape twisting.

Outer layer strand 3 gulps down Shi-Xi Lushi composite structure for K46SeWS Xi Lushi-Wa Lin, in stock, steel wire divides four layers from inside to outside, central core is made up of 1 core wire 31 and 6 peripheral steel wire 32 outside it, and the second layer is made up of 8 second layer steel wires 33, is point cantact between central core and the second layer; Third layer is made up of 16 third layer steel wires, wherein 8 is third layer thick wire 34,8 is third layer finer wire 35, thickness steel wire is spaced, the recess of adjacent two second layer steel wires 33 places third layer thick wire 34, the high spot of every root second layer steel wire 33 twists with the fingers upper third layer finer wire 35, is linear contact lay between the second layer and third layer; Outermost layer is made up of 16 outermost layer steel wires 36, is enclosed in the outside of third layer equably, and outermost layer steel wire 36 is thick wire, and for face contacts between third layer with the 4th layer, the method for carrying out compacting by 5% compression ratio makes to be face contact between outermost layer steel wire 36.

The present invention improves conventional steel wire rope, combine the feature that Xi Lushi-Wa Lin gulps down formula structure of steel wire, create Xi Lushi-Wa Lin and gulp down Shi-Xi Lushi composite structure, in outer layer strand 3, the second layer and outermost layer steel wire adopt Xi Lushi to guarantee steel wire rope ABRASION RESISTANCE, a third layer employing watt woods gulps down formula and guarantees steel wire rope softness, utilize steel wire point cantact and linear contact lay advantage separately, the process characteristic of point cantact is adopted between central core and the second layer, make steel wire rope more soft, third layer is linear contact lay, outermost layer adopts the process characteristic of die drawing to make between steel wire as area touches, take full advantage of a little, line, the feature of facial-contracted wire rope, both the feature that these steel wire ropes are excellent had been kept, improve again their weak point, improve steel wire rope anti-wear performance and softness, thus improve the service life of steel wire rope.
