Abstract
The steel wire structure of the large-diameter single-stranded steel wire rope is sequentially arranged from inside to outside as 1+6+12+18+24+21+27+33+36+45, and the diameters of the steel wires are sequentially as follows from inside to outside: the steel wire is twisted in nine layers, each layer adopts a point contact structure, steel wires have equal twist angles in the structure, and the twist directions of two adjacent layers are opposite. The invention has reasonable structure, stable structure, no rotation and good straightness; the composite material has the advantages of high breaking tension, large elastic modulus and good non-rotation performance; the use requirements of large-scale building markets such as space truss suspension cable structure construction, space guy cable type stadium steel structure awning, ship anchoring and the like on steel wire rope products are met.
Description
Technical Field
The invention relates to a large-diameter single-stranded steel wire rope, and belongs to the technical field of metal products.
Background
The large-diameter single-stranded rope is widely applied to large buildings such as space truss suspension cable structure construction, space guy cable type stadium steel structure awning, ship anchoring and the like due to the fact that the large-diameter single-stranded rope has high breaking tension, high elastic modulus and good non-rotation performance, is an international new popular building high added value, high technical content and green product, and has wide market prospect.
Disclosure of Invention
The invention aims to provide a large-diameter single-stranded steel wire rope product with high technical requirements such as high tensile strength, large elastic modulus and the like, and meets the use requirements of large-scale building markets such as space truss suspension cable structure construction, space guy cable type stadium steel structure awning, ship anchoring and the like on the steel wire rope product.
The steel wire structure of the large-diameter single-stranded steel wire rope is sequentially arranged from inside to outside as 1+6+12+18+24+21+27+33+36+45, and the diameters of the steel wires from inside to outside are respectively as follows: the steel wire is twisted in nine layers, each layer adopts a point contact structure, steel wires have equal twist angles in the structure, and the twist directions of two adjacent layers are opposite.
The beneficial effects of adopting the above technical scheme are as follows:
1. the invention has reasonable structure, and the adjacent two layers of the single-stranded rope adopt opposite twisting directions so as to ensure the stable structure, the irrotation and the good straightness of the steel wire rope.
2. The invention has the advantages of high breaking tension, large elastic modulus and good non-rotation performance.
3. The invention meets the use requirements of large-scale building markets such as space truss suspension cable structure construction, space guy cable type stadium steel structure awning, ship anchoring and the like on steel wire rope products.
Drawings
FIG. 1 is a schematic cross-sectional view of the present invention.
The specific implementation mode is as follows:
the invention is described in further detail below with reference to the accompanying drawings:
as shown in fig. 1, the steel wire structure of the large-diameter single-strand steel wire rope is arranged as 1+6+12+18+24+21+27+33+36+45 from inside to outside.
The diameters of the steel wires are as follows from inside to outside in sequence: 5.40mm, 4.30mm, 6.40mm, nominal diameter 102 mm.
The invention is divided into nine layers of twisting, each layer adopts a point contact structure, the steel wires have equal twisting angles in the structure, the adjacent two layers of twisting are opposite in twisting direction and are produced by adopting the pre-deformer, the twisting stress is reduced, the deformation rate of the steel wires reaches 75-80 percent, the steel wires have good non-loosening performance, and the twisting is uniform and compact.
The invention is detected that the elastic modulus reaches 1.58X105The MPa, the total breaking tension reaches 11409.0KN, and various performance indexes reach or exceed the design requirements.
