Technical field

The utility model relates to a kind of metallic cable, is meant that specifically high-rise express elevator uses steel wire rope.

Background technology

At present; Domestic skyscraper is more and more, and the speed that requires to promote also is more and more faster, and the demand of high-rise express elevator increases day by day; The steel wire rope that this just need match with it; Present high-rise express elevator mainly is the steel wire rope of 8 * 19S-8 * 7 and 8 * 19W-8 * 7-1 * 19W structure with steel wire rope, and all because its ABRASION RESISTANCE and flexibility all are difficult to satisfy necessary requirement, it is limited that steel wire rope carries rupture pull force for these two kinds of structures.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of rupture pull force high, and wear-resisting, soft high-rise express elevator is used steel wire rope.

The technical scheme that solves the problems of the technologies described above is:

High-rise express elevator is used steel wire rope, comprises 1 central strand, 9 internal layer thighs and 9 outer layer strand, and said central strand outside evenly is surrounded by one deck internal layer thigh, and it is root rope that central strand and internal layer thigh are twisted into, and said outer layer strand is wrapped sth. made by twisting equably in the steel wire rope outermost; Contact condition between internal layer thigh and the outer layer strand contact for point, and said central strand is that 1 * 19W watt of woods gulps down line contact strand, and the internal layer thigh is 1 * 7 line contact strand, and outer layer strand is 1 * 17S Xi Lushi line contact thigh.

Further, said central strand comprises 19 steel wires, is divided into two layers, is Wa Lin and gulps down line contact shape; Wherein one is core wire; The ground floor steel wire is twisted with the fingers in core wire outside evenly bag; The ground floor steel wire comprises 6 with diameter wire and be the line contact condition, and said ground floor steel wire outside bag is twisted with the fingers has second layer steel wire, and said second layer steel wire comprises the steel wire of 12 different-diameters; Wherein 6 are line contact shape with the diameter thick wire and are embedded in the recess that adjacent two ground floor steel wires form, 6 with the diameter finer wire be line contact shape and respectively bag twist with the fingers the bossing that forms at 6 ground floor steel wires.

Further, said internal layer thigh comprises that 7 are line contact steel wire, and wherein one is core wire, and 6 same diameter wire are being twisted with the fingers in core wire outside evenly bag.

Further, said outer layer strand comprises 17 steel wires, is divided into two layers, is Xi Lushi line contact shape; Wherein one is core wire; The ground floor steel wire is twisted with the fingers in core wire outside evenly bag; The ground floor steel wire comprises 8 with diameter wire and be the line contact condition, and ground floor steel wire outside bag is twisted with the fingers has second layer steel wire, second layer steel wire to comprise 8 with diameter and the steel wire thick than the ground floor steel wire diameter; Second layer steel wire is embedded in the recess that adjacent two ground floor steel wires form, and is line with the ground floor steel wire and contacts shape.

The high-rise express elevator of the utility model adopts secondary property sth. made by twisting system to form when closing rope with steel wire rope; For the first time earlier with center line thigh and internal layer thigh 9 * 7-1 * 19W synthon both wire rope cores of steel wire rope of restricting; For the second time with 9 thighs of outer layer strand through noseplate every thigh rationally separately after, round wire rope core through pre-former carry out screw type twist with the fingers make after, compress through mould; Eliminate the residual stress in the strand through the post-formers of too much organizing many wheels again; Effectively reduced the construction of wire rope elongation, guaranteed that wirerope diameter is even, made it not only guarantee strong ABRASION RESISTANCE, but also have flexibility preferably.Because the structural stretch of this structure is little and diameter is even, make steel wire rope in service steadily at elevator; This structure has strong ABRASION RESISTANCE, and having preferably flexibility and steel wire rope effective metal area has again increased by 4%, carries rupture pull force thereby improved steel wire rope, has prolonged steel wire rope service life.

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Embodiment 1

As shown in Figure 1, high-rise express elevator is used steel wire rope, and model is 9 * 17S-9 * 7-1 * 19W-￠ 10mm, comprises central strand 1 (￠ 3.0mm), internal layer thigh 2 (￠ 1.35mm) and outer layer strand 3 (￠ 2.4mm).

This elevator wire rope has 19 strands, divides two layers, strand with strand between contact condition for the some contact, guarantee the flexibility of steel wire rope, internal layer thigh 2 wrap symmetrically the sth. made by twisting central strand 1, outer layer strand 3 wrap symmetrically the sth. made by twisting in the steel wire rope outermost; Wherein, central strand is that 1 * 19W structure of better softness is formed, and the internal layer thigh is that 9 * 7 good structures of flexibility are formed, and outer layer strand is that the stronger 9 * 17S structure of ABRASION RESISTANCE is formed.The combination of this structure, the effective area of raising steel wire rope increases the steel wire rope ABRASION RESISTANCE with Xi Lushi as outer layer strand.

As shown in Figure 2; Central strand 1 comprises that 19 steel wires are Wa Lin and gulp down line contact shape; Be divided into two layers, wherein one is core wire 11, and core wire 11 outsides are evenly wrapped and twisted with the fingers 6 with the ground floor steel wire 12 of diameter and be the line contact condition; The second layer has the steel wire of 12 different-diameters; Wherein 6 are line contact shape with diameter thick wire 13 and embed the recess that adjacent two ground floor steel wires 12 form, all the other 6 with diameter finer wire 14 be line contact shape and respectively bag twist with the fingers the bossing that forms at 6 ground floor steel wires 12, and embed the recess that adjacent two thick wires 13 form.

As shown in Figure 3, internal layer thigh 2 comprises 7 superfine round wires, and wherein one is core wire, all the other 6 steel wires symmetrically, be line and wrap touchingly and twisting with the fingers core wire.This structure has the advantages that the steel wire number is few, the steel wire contact condition is relatively stable, and flexibility is good.

Center line thigh 1 is twisted into root rope with internal layer thigh 2.

As shown in Figure 4, outer layer strand 3 comprises 17 steel wires, is Xi Lushi line contact shape; Be divided into two layers, wherein one is core wire 31, and core wire 31 outsides are evenly wrapped and twisted with the fingers the ground floor steel wire; The ground floor steel wire comprises 8 with diameter wire 32 and be the line contact condition; Ground floor steel wire outside bag is twisted with the fingers has second layer steel wire, second layer steel wire to comprise 8 with diameter and the steel wire 33 thick than ground floor steel wire 32 diameters, embeds the recess that adjacent two ground floor steel wires 32 form.This structure can be guaranteed the softness of steel wire rope, can guarantee the ABRASION RESISTANCE of steel wire rope again.

The high-rise express elevator of the utility model adopts secondary property sth. made by twisting system to form when closing rope with steel wire rope, because the structural stretch of this structure is little and diameter is even, makes steel wire rope in service steadily at elevator; This structure has strong ABRASION RESISTANCE, and having preferably flexibility and steel wire rope effective metal area has again increased by 4%, carries rupture pull force thereby improved steel wire rope, has prolonged steel wire rope service life.
