Description

High-rise express elevator steel wire rope

Technical field

The present invention relates to a kind of metallic cable, specifically be meant high-rise express elevator steel wire rope.

Background technology

At present, domestic skyscraper is more and more, the speed that requires to promote also is more and more faster, 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 these two kinds of structures are all because its ABRASION RESISTANCE and flexibility all are difficult to satisfy necessary requirement, and steel wire rope carrying rupture pull force is limited.

Invent novel content

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

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

High-rise express elevator steel wire rope comprises 1 central strand, 9 internal layer thighs and 9 outer layer strand, and described central strand outside evenly is surrounded by one deck internal layer thigh, and central strand and internal layer thigh twisting become a root rope, and described 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 described 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, described 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, described ground floor steel wire outside bag is twisted with the fingers second layer steel wire, described 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, described 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, described 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, ground floor steel wire outside bag is twisted with the fingers second layer steel wire, second layer steel wire comprises 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 present invention adopts the secondary twisting 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 rope both wire rope core of steel wire rope, after for the second time 9 thighs of outer layer strand rationally being separated every thigh by noseplate, round wire rope core through after pre-former carries out the screw type twisting, compress by mould, the post-formers of taking turns through too much group are eliminated the residual stress in the strand more again, effectively reduced the construction of wire rope elongation, guarantee that wirerope diameter is even, make it both guarantee strong ABRASION RESISTANCE, has flexibility preferably again.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%, thereby has improved steel wire rope carrying rupture pull force, has prolonged steel wire rope service life.

The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.

Embodiment 1

As shown in Figure 1, high-rise express elevator steel wire rope, 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, core wire 11 outsides are evenly wrapped and are 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 a root rope with internal layer thigh 2.

As shown in Figure 4, outer layer strand 3 comprises 17 steel wires, be 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 present invention adopts the secondary twisting 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%, thereby has improved steel wire rope carrying rupture pull force, has prolonged steel wire rope service life.
