Abstract
The utility model relates to a triangular strand wire rope with a line contact structure. The triangular strand wire rope comprises an outer-layer wire strand with a line diameter D1, an inner-layer wire strand with a line diameter D2, a triangular strand iron wire with a line diameter D3 and an edge filling iron wire. The triangular strand wire rope with the line contact structure is characterized in that the ratio of the lay length values of the inner-layer wire strand and the outer-layer wire strand is (40-44)/(46-51). Compared with the prior art, the triangular strand wire rope has the beneficial effects that the wire rope is easily realized, and the process change is small; the triangular strand wire rope with the line contact structure retains the advantage of a point contact structure and meanwhile increases the advantages of compact structure, good contact state of wires in strands, good twisting state, high breakage tension of the whole rope and the like; the outer diameter is not changed; and the triangular strand wire rope with the line contact structure is the updated product of the triangular strand wire rope with the point contact structure.
Description
Technical field
The utility model relates to the triangular strand wire rope field, relates in particular to a kind of line contact structures triangular strand wire rope.
Background technology
The triangular strand wire rope primary structure a bit contacts and contacts two kinds with line at present, the point-contact junction structure mainly contains models such as 6V * 30,6V * 33,6V * 34,6V * 36,6V * 37,6V * 43, the line contact structures mainly contain 6V * 37S model, identical steel wire is counted the contact of steel wire rope yarn and is compared with the point-contact junction structure, the number of plies is identical, the line contact structures have twisting wire rope closely, strand in good, the good stability of steel wire contact condition, minimum breaking force coefficient advantages of higher, but produce and continue to use old technology always, triangular strand wire rope is in the majority with the point-contact junction structure.
Summary of the invention
The purpose of this utility model provides a kind of line contact structures triangular strand wire rope, the production line that makes point-contact junction structure triangular strand wire rope under the little situation of process reform, production line contact structures steel wire rope.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of line contact structures triangular strand wire rope, the cover wire thigh, the steel wire of internal layer thigh of line footpath D2, the triangular strand iron wire of line footpath D3, the benefit rib iron wire that comprise line footpath D1, cover wire number of share of stock and steel wire of internal layer number of share of stock differ three, it is characterized in that the steel wire of internal layer thigh is (40~44)/(46~51) with the lay pitch value of cover wire thigh than scope.
Compared with prior art, the beneficial effects of the utility model are: realize easily, technique change is little, line contact triangular strand wire rope had both kept the advantage of point-contact junction structure, increased again simultaneously structure closely, strand in the steel wire contact condition good, the twisting state is good, whole rope rupture pull force advantages of higher, outside dimension is constant, is the regeneration product of point-contact junction structure triangular strand wire rope.
Description of drawings
Fig. 1 is the utility model embodiment section structure schematic diagram.
Among the figure: 1-cover wire thigh 2-steel wire of internal layer thigh 3-triangular strand iron wire 4-mends the rib iron wire
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is a kind of line contact structures of the utility model triangular strand wire rope embodiment section structure schematic diagram, the prerequisite that the point-contact junction structure can be transformed into line contact structures steel wire rope is that cover wire number of share of stock and steel wire of internal layer number of share of stock differ three, with 6V * 43S-∮ 60mm point-contact lay wire rope is example, triangular strand iron wire 3 diameter ∮ 2.55mm, steel wire of internal layer thigh 2 diameter ∮ 2.7mm, cover wire thigh 1 diameter ∮ 3.2mm from inside to outside, strand structural formula be/1 * 7+3/+15+18.
When strand is pressed the production of line contact structures, adjust pitch by normal technology, roll spacing and press-bending value, preceding string and middle string fuselage rotating ratio are 44/51, guarantee that the steel wire of internal layer thigh 2 and the lay pitch value ratio of cover wire thigh 1 are 44/51, check strand arranging situation of each layer steel wire, determine whether wire distribution technology is reasonable, the line of triangular strand iron wire 3 footpath ∮ 2.6mm from inside to outside, steel wire of internal layer thigh 2 lines footpath ∮ 2.75mm, cover wire thigh 1 line footpath ∮ 3.2mm, steel wire of internal layer thigh 2 is not complete line contact condition with cover wire thigh 1 among the figure, be owing to due to theoretical the picture, will reach the line contact condition through the pressure roller extruding during actual production.
Finished product closes rope inspection, checks mainly whether structural stability is good, and original three of contact condition mended rib iron wire 4 shakinesses, often is expressed into the outer surface of thigh, by changing the line contact structures into, solved this problem.Check whether product structure is the test of line contact structures, the ratio of absolutely dissolution of partnership steel wire pulling force test and whole rope rupture pull force, compares with the point-contact junction structure, and the superiority of structure is obvious.
Claims (1)
1. line contact structures triangular strand wire rope, the cover wire thigh, the steel wire of internal layer thigh of line footpath D2, the triangular strand iron wire of line footpath D3, the benefit rib iron wire that comprise line footpath D1, it is characterized in that the steel wire of internal layer thigh is (40~44)/(46~51) with the lay pitch value of cover wire thigh than scope.
