Abstract
The utility model discloses a traction steel wire rope for a machine roomless elevator, which comprises two parts, i.e. a central strand and external strands, wherein the external strands symmetrically wrap the central strand, and the central strand adopts a sisal rope core. The traction steel wire rope has a simple, reasonable and compact structure; and compared with the traditional eight-strand sisal core filled type steel wire rope, the six-strand filled type steel wire rope has high reelability, large bearing capacity, high abrasion resistance, smaller elongation rate and lower production cost. The traction steel wire rope is suitable for the machine roomless elevator.
Description
Technical field
The utility model relates to a kind of steel wire rope, specifically is meant the machine-roomless lift traction steel-cable.
Background technology
Do not take machine room space, environmental protection, advantage such as energy-conservation because machine-roomless lift has, in recent years, this type of elevator development is very fast, utilization ground more and more widely, market is more and more big.At present, machine-roomless lift is in the majority with 8*19S+NF structure class steel wire rope, and the reelability of this class steel wire rope is bad, and bearing capacity is relatively poor, and production cost is higher simultaneously.
The utility model content
The purpose of this utility model is, at the problems referred to above, proposes a kind of machine-roomless lift traction steel-cable, with advantage such as realize that production cost is low, the reelability of steel wire rope can be good, percentage elongation is little, ABRASION RESISTANCE is high and bearing capacity is big.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Machine-roomless lift comprises central strand and outer layer strand two parts with traction steel-cable, and described outer layer strand symmetry bag is twisted with the fingers central strand.
Further be improved to, described steel wire rope is to twist with the fingers the central strand twisting by 6 outer layer strand bags to form, and central strand adopts Sisal Hemp Rope Core.
Moreover outer layer strand is to be the filled type twisting by the inside and outside two-layer inclined to one side finer wire of same diameter and center thick wire of 6 finer wire bag sth. made by twisting to form.Wherein, 6 of steel wire of internal layer, 12 of cover wires are filled 6 finer wires between internal layer and the cover wire, be the filled type twisting and form.
The utlity model has following beneficial effect;
1, because machine-roomless lift adopts the filled type structure with the traction steel-cable outer layer strand, and in use, it has higher antifatigue bending property, steel wire rope can reach 18.5 around coefficient, contrast 8*19S+NF structure reelability improves 20%.
2, machine-roomless lift can reach 0.356 with the rupture pull force coefficient of traction steel-cable, and contrast 8*19S+NF structure improves more than 20%, contrasts the 8*19S+NF steel wire rope that present conventional lift uses, and the percentage elongation of 6 strands of filled type steel cord structures decreases.
3, because twisting with the fingers the central strand twisting by 6 outer layer strand bags, steel wire rope forms, compare the steel wire rope of 8 outer layer strand of same size, 6 strands steel wire rope has directly increased 20-25% at the outer layer strand thigh, production efficiency has improved more than 30%, reduced production cost greatly, because burst footpath is thicker, cover wire silk footpath is thick, has also improved the steel wire rope ABRASION RESISTANCE to a certain extent simultaneously.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawing:
Fig. 1 is the utility model machine-roomless lift traction steel-cable cross section structure schematic diagram;
Fig. 2 is the outer layer strand cross section structure schematic diagram of the utility model machine-roomless lift with traction steel-cable;
Mark is illustrated as among Fig. 1: 1 central strand (Sisal Hemp Rope Core), 2 outer layer strand.
Mark is illustrated as among Fig. 2: 3 thick wires, 4 inclined to one side finer wires, 5 finer wires.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the machine-roomless lift traction steel-cable comprises central strand 1 and outer layer strand 2, and outer layer strand is wrapped symmetrically and twisted with the fingers central strand 1.
Its preparation method is:
Arranged steel wire by noseplate twisting with the fingers on strand car, produced desired structure, eliminated the stress of thigh again through post-former effectively, be received on the I-beam wheel then through closing up mouthful to compress with the line ball punching block.Be prepared into filled type outer layer strand 2.
Close when restricting, wrap sth. made by twisting central strand 1 (Sisal Hemp Rope Core) by 6 outer layer strand 2 earlier and on finished car, arrange,, compress by closing up mouth again, effectively eliminate the stress of thigh again through post-former, be received in then and form steel wire rope on the I-beam wheel through pre-former by noseplate.
Because steel wire rope is twisted with the fingers central strand (Sisal Hemp Rope Core) twisting by 6 outer layer strand bags and is formed, compare the steel wire rope of 8 outer layer strand of same size, the unit steel wire diameter that 6 strands steel wire rope distributes at skin than 8 strands slightly, the contact area of steel wire rope and traction sheave increases, and the ABRASION RESISTANCE of steel wire rope also improves greatly.
Simultaneously, because described outer layer strand is to twist with the fingers central strand (Sisal Hemp Rope Core) by 6 outer layer strand bags, its each outer layer strand is to be the filled type twisting by the inside and outside two-layer inclined to one side finer wire of same diameter and center thick wire of 6 finer wire bag sth. made by twisting to form, in use, the steel wire rope of this structure has higher antifatigue bending property, improve the reelability of steel wire rope greatly, and then improved the bearing capacity of steel wire rope.Contrast the 8*19S+NF steel wire rope that present conventional lift uses, the rope stretch rate of 6 bursts of filled type structures has reduced by 2%, and production cost is also reduced greatly in addition.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
