Abstract
The invention discloses a steel wire rope for a suspension bridge sling. The structure of the steel wire rope is 8*K65FNS+IWRC. The steel wire rope is composed of a center strand, six or eight inner-layer strands and eight outer-layer strands. The structure of the center strand is 55SWS, the structure of the inner-layer strands is 1*41WS or 55SWS, and the outer-layer strand is 65FNS. The center strand, inner-layer strands and outer-layer strands are all compacted with a roller and subjected to plastic coating, steel wires of the steel wire rope are in surface contact, and the strands of the steel wire rope are in line contact; the steel wire rope is compact in structure, high in wear resistance, fatigue resistance and bearing capacity, and long in service life.
Description
Technical field
The present invention relates to a kind of sling of suspension bridge steel wire rope and manufacture method thereof, belong to metallic article processing technique field.
Background technology
In prior art, sling of suspension bridge steel cord structure is 8 × 41WS+IWR or 8 × 55SWS+IWR etc., and wirerope diameter is 60-88mm, and steel wire rope outer layer strand is stereotyped writing steel wire rope, wire rope core is six strand contact structures, in linear contact lay state between composition steel wire in strand wire.The sling of suspension bridge steel cord structure of the present invention is 8 × K65FNS+IWRC, this steel wire rope is by a central strand, the six roots of sensation or eight internal layer stocks and eight outer layer strand primary twistings are constituted, central strand and internal layer stock-traders' know-how are compacted and carry out plastic-coated, outer layer strand twisting at twice, it is compacted after twisting for the first time, carry out second time twisting compacting again, this strand wire is surface contact state, structure is tightr, steel wire rope contact area is big, contact stress is little, there is not the second order buckling between steel wire, the metal filled coefficient of steel wire rope is high, effective metal area is big, bearing capacity and the fatigue performance of steel wire rope are greatly improved.Owing to this steel wire rope is through overcompaction with after filling out and moulding process, steel wire rope anti-wear performance and fatigue performance significantly improve.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that the technical problem that a kind of sling of suspension bridge steel wire rope and manufacture method thereof, solution steel wire rope anti-wear performance and fatigue performance are low, improve service life of steel wire rope.
The sling of suspension bridge steel wire rope of the present invention, its structure is 8 × K65FNS+IWRC, is made up of a central strand, the six roots of sensation or eight internal layer stocks and eight outer layer strand；
Described central strand structure is 55SWS, is made up of 55 steel wire primary twistings；
Described internal layer stock structure is 1 × 41WS or 55SWS, is made up of at least 41 steel wire primary twistings；
Described outer layer strand structure is 65FNS, is made up of 65 steel wire secondary twistings.
The manufacture method of the sling of suspension bridge steel wire rope of the present invention, including implementing step as follows:
1) twisting central strand, again through roller compaction after central strand twisting molding, compacting rate is 7-13%, and making central strand is surface contact structure state, after carry out plastic-coated process again, plastic layer is 1-3mm；
2) twisting internal layer stock, then through roller compaction, compacting rate is 6-12%, makes internal layer stock be changed in surface contact structure state by contact structure, after carry out plastic-coated process again, plastic layer is 1-3mm；
3) twisting outer layer strand, outer layer strand structure is 1+6+6F+12-20+20, the stock internal layer of twisting at twice, first primary twisting 1+6+6F+12 structure, then carries out roller compaction, compacting rate is 6-12%, then centered by stock internal layer, the stock outer layer of two-layer 20+20 structure twisted with the fingers by bag again, then outer layer strand is carried out roller compaction, and compacting rate is 6-12%, after carry out plastic-coated process again, plastic layer is 1-3mm；
4) twisting finished product steel wire rope, by a central strand, the six roots of sensation or eight internal layer stocks and eight outer layer strand primary twisting molding, in linear contact lay state between strand wire and stock, in surface contact state between steel wire and steel wire.
Due to the fact that steel wire rope central strand, internal layer stock and outer layer strand are all through roller compaction, in surface contact structure state between steel wire rope steel wire and steel wire, each stock uses primary twisting mode, make between strand wire and stock in contact structure state, the each stock of steel wire rope has all carried out plastic-coated process, makes steel cord structure tight, and anti-wear performance and fatigue performance are good, bearing capacity is big, and service life of steel wire rope is high.
Accompanying drawing explanation
Fig. 1 is one sling of suspension bridge construction of wire rope schematic diagram of the present invention.
In figure: 1 central strand, 2 internal layer stocks, 3 outer layer strand.
Detailed description of the invention
Below in conjunction with accompanying drawing, one sling of suspension bridge steel wire rope of the present invention and manufacture method thereof are described in further detail:
In Fig. 1, the sling of suspension bridge steel wire rope of the present invention, its structure is 8 × K65FNS+IWRC, is made up of a central strand 1, the six roots of sensation or eight internal layer stocks 2 and eight outer layer strand 3；
Described central strand 1 structure is 55SWS, is made up of 55 steel wire primary twistings；
Described internal layer stock 2 structure is 1 × 41WS or 55SWS, is made up of at least 41 steel wire primary twistings；
Described outer layer strand 3 structure is 65FNS, is made up of 65 steel wire secondary twistings.
The manufacture method of the sling of suspension bridge steel wire rope of the present invention, including implementing step as follows:
1) twisting central strand 1, again through roller compaction after central strand 1 twisting molding, compacting rate is 7-13%, make central strand 1 in surface contact structure state, after carry out plastic-coated process again, plastic layer is 1-3mm；
2) twisting internal layer stock 2, then through roller compaction, compacting rate is 6-12%, makes internal layer stock 2 be changed in surface contact structure state by contact structure, after carry out plastic-coated process again, plastic layer is 1-3mm；
