Abstract
The utility model discloses a micro-rotating steel wire rope for a high-rise and high-speed elevator, which comprises a central strand, inner layer strands and outer layer strands, wherein the eight inner layer strands are evenly covered and entwisted at the outer side of the central strand; and the eight outer layer strands are evenly covered and entwisted at the outer sides of the inner layer strands. Compared with the steel wire rope of the traditional elevator, the micro-rotating steel wire rope for the high-rise and high-speed elevator is strong in carrying capacity, good in rotation performance, low in elongation, even in diameter ramrod and suitable for the high-rise and high-speed elevator.
Description
Technical field
The utility model relates to a kind of steel wire rope, relates in particular to the little rotating wire rope of a kind of high-rise express elevator.
Background technology
Because the fast development of high-rise express elevator, terraced speed is more and more higher, and requirements of Wire Rope is also being improved.Common elevator comprises that with 8*19S+NF (please this structure being explained in detail) structure steel core, half steel cored structure class steel wire rope can't satisfy the use of the high-rise express elevator of part, the bearing capacity of this class steel wire rope is relatively poor, resistance rotation performance is good inadequately, productivity ratio height, the uniformity of diameter poker are also good inadequately.
The utility model content
The purpose of this utility model is, at the problems referred to above, provide a kind of high-rise express elevator little rotating wire rope, satisfy the use of high-rise express elevator in the hope of acquisition bearing capacity, anti-verticity, elongation performance, all good elevators of diameter poker with steel wire rope.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
The little rotating wire rope of high-rise express elevator comprises central strand, internal layer thigh and outer layer strand, is characterized in: the number of described internal layer thigh is that 8 also even bags are twisted with the fingers in the outside of central strand, and the number of described outer layer strand is 8 and the even outside of twisting with the fingers at the internal layer thigh of wrapping; Described outer layer strand is the Xi Lushi structure, and the center is 1 core wire, twists with the fingers the internal layer that core wire is formed in the core wire outside for evenly being wrapped by 8 finer wires, is that evenly bag is twisted with the fingers the skin of forming at 8 thick wires in the internal layer outside in the internal layer outside; Described internal layer thigh comprises 1 core wire and evenly wraps 6 steel wires twisting with the fingers in the core wire outside; Described central strand gulps down the formula structure for a watt woods, the center is 1 core wire, in the outside of core wire is the internal layer that evenly wraps 6 thick wires compositions twisting with the fingers core wire, in the internal layer outside be by 6 thick wires, 6 skins that finer wire is formed, described slightly, finer wire wraps the outside of sth. made by twisting at internal layer at interval; Strand with thigh between, be line between steel wire and the steel wire and contact.The definition of thick wire and finer wire is that both compare, as long as the diameter of thick wire just can greatly than the diameter of finer wire.
High-rise express elevator may further comprise the steps with the preparation method of little rotating wire rope:
A, twist with the fingers strand: arranged steel wire by noseplate twisting with the fingers on strand car, produced central strand, internal layer thigh and outer layer strand respectively through closing up mouthful to compress with the line ball punching block;
B, an elimination strand stress: the stress of eliminating thigh through post-former;
C, close rope: twist with the fingers central strand by 8 outer layer strand and 8 outer layer strand bags and arrange by noseplate on finished car, through pre-former, mouthful compress by closing up again, the stress of eliminating effectively strand through post-former is received in then and makes steel wire rope on the I-beam wheel again.
The utlity model has following beneficial effect;
1, because high-rise express elevator adopts 8 strands of Lang lay ropes with little rotating wire rope, has advantages of high bearing capacity, the minimum breaking force coefficient can reach 0.405, improve nearly 40% than common 8*19S+NF structure steel wire rope, improve nearly 15% than 8*19S structural steel independent wire strand core wire rope, use the steel wire rope of same size, Lang lay rope has improved the security of elevator greatly.
2, every meter anglec of rotation of described 8 strands of Lang lay ropes descends above 80% than common 8*19S+NF structure steel wire rope under identical load condition, descend above 50% than 8*19S structural steel independent wire strand core wire rope, improved the resistance rotation performance of steel wire rope greatly, for the installation of steel wire rope, use powerful guarantee be provided, and improved to a certain extent the service life of steel wire rope.
3, described 8 strands of Lang lay rope weight coefficients can reach 0.457 and improve nearly 35% than common 8*19S+NF structure steel wire rope, improve 12% than 8*19S structural steel independent wire strand core wire rope, use the steel wire rope of same size, Lang lay rope has improved the density of steel wire rope greatly, thereby improved the diameter uniformity of steel wire rope, anti-extrusion and ABRASION RESISTANCE, and reduced the elongation performance of steel wire rope.
