Abstract

The invention discloses a steel wire rope for an elevator, which comprises a central portion, a first steel wire bundle layer and a second steel wire bundle layer, wherein the first steel wire bundle layer wraps the central portion, and the second steel wire bundle layer wraps the first steel wire bundle layer. The central portion comprises four first steel wires, second steel wires and third steel wires, wherein the first steel wires are mutually tangential to form a round section shape, the second steel wires are arranged outside the first steel wires, and the third steel wires are arranged among the second steel wires at intervals. The first steel wire bundle layer comprises eight second steel wire bundles in a mutually tangential manner, and the second steel wire bundle layer comprises eight first steel wire bundles in a mutually tangential manner. The steel wire rope for the elevator has the advantages that structural steel wire rope strands are many, steel wires in each strand are small in specification, each steel wire is high in strength and toughness, the steel wire rope is high in integral breaking force, contact stress of the strands of the steel wire rope is small, frictional force among the strands of the steel wire rope is decreased, and the service life of the steel wire rope can be effectively prolonged.

Description

A kind of elevator wire rope

Technical field

The present invention relates to a kind of steel wire rope, particularly a kind of result of use that can effectively improve equipment, operational efficiency, the elevator wire rope of steel wire rope long service life belongs to the steel wire rope product technique field.

Background technology

High strength, high performance elevator wire rope belong to a kind of elevator wire rope of special construction, are all kinds of elevators, mechanical lifting usefulness, the very large a kind of steel wire rope of use amount; The high rupture pull force of conventional lift steel wire rope is low, softness is bad, causes the service life of steel wire rope shorter.

Summary of the invention

Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of result of use that can effectively improve equipment, operational efficiency, the elevator wire rope of steel wire rope long service life.

The technical solution of the present invention is achieved: an elevator rope, including the center portion, a first layer of wire bales, bales of the second layer wire; said first layer of wire wrapped bales of the central portion; said second layer wire bales The first layer of wire wrapped bales; said central portion includes a second wire, the third wire, a first wire; the first four wires of each other to form a circular shape tangent; said second wire set the outside of the first wire, said second spacing between the wires provided with a third wire; said first layer steel wire bales from eight bales of second tangent to each other to form; the second layer 8 by a wire bales tangent to each other to form a first wire bales.

Preferably, said second steel wire has 4; 2 the 3rd steel wires are set between said second steel wire at interval.

Preferably, the 3rd gauge of wire is less than second steel wire.

Because the utilization of technique scheme, the present invention compared with prior art has advantage:

The structure steel wire number of strands of elevator wire rope of the present invention is many; Wire gauge is little in strand; Intensity of steel wire and toughness are high, and steel wire rope has very high whole rope rupture pull force, and the compact stress between each strand of steel wire rope is little; Reduce the frictional force between each strand in the steel wire rope, can effectively improve the service life of steel wire rope; Steel wire diameter in the steel wire rope is thinner, and intensity is high, has characteristics such as high rupture pull force, softness are strong, has better serviceability than general boom hoist cable, has improved the service life of steel wire rope, is promoted the use of widely.

Description of drawings

Below in conjunction with accompanying drawing technical scheme of the present invention is described further:

Fig. 1 is the sectional view of elevator wire rope of the present invention;

Wherein: 1, the first wire bales; 2, the second wire bales; 3, a second wire; 4, the third wire; 5, the first wire.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described.

As shown in Figure 1 of the present invention said one elevator rope, including the center portion, a first layer of wire bales, bales of the second layer wire; said first layer of wire wrapped bales of the central portion; said second layer wire the first layer of wire wrapped bales bales; said central portion includes a second wire 3, the third wire 4, the first wire 5; said first wires 5 is four, each tangent to a circular shape is formed; the said second wire 3 disposed on the outside of the first wire 5, the spacing between said second wire 3 is provided with a third wire 5; said first layer wire bales bales by eight wires 2 of second tangent to each other is formed; said second layer steel wire bales bales by the 8 first tangent to each other to form 1; the second wire 3 has four; said second wire 3 are spaced two third wire 4; third wire 4 a smaller diameter than the second wire 3.

The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.

Claims

1 An elevator rope, wherein: including the center portion, a first layer of wire bales, bales of the second layer wire; said first layer of wire wrapped bales of the central portion; said second layer the first layer of steel wires wrapped bales bales; said central portion includes a second wire, the third wire, a first wire; the first four wires of each other to form a tangent to the circular cross section shape; said second wire disposed between the first wire outside the interval between said second wire is provided with a third wire; said first layer steel wire bales by eight bales of second tangent to each other is formed; the second layer 8 from the first wire bales bales each wire Tangent shape.

2. elevator wire rope according to claim 1 is characterized in that: said second steel wire has 4; 2 the 3rd steel wires are set between said second steel wire at interval.
