Abstract

The utility model relates to a steel wire rope used for a height operation hanging basket. The steel wire rope is formed by twisting core strands (1) and periphery strands (2) and is characterized inthat an exposed surface (2.1.1) of each steel wire (2.1) of the periphery strands (2) is a forging surface through forging, and the tight ground contact state is formed between the steel wires (2.1).The steel wire rope has the advantages that: 1, when the steel wire rope is used, the steel wire rope is surface contact with a sheave groove, and the friction force is great, therefore, the steel wire rope and the sheave groove are not easy to slip, and the safety is high; 2, the surface of the steel wire rope is forged, the contact area between the steel wire rope and the sheave groove becomes larger, the stress in unit area is small, therefore, the wear resistance is improved, and the steel wire at the surface is uneasy to fracture; 3, through the forging, the metal density coefficient is improved, the fractured tension becomes greater, the service performance is improved and the service life is prolonged.

Description

The aerial work basket steel wire rope

(1) technical field

The utility model relates to a kind of steel wire rope, relates in particular to a kind of aerial work basket steel wire rope.

(2) background technology

Aerial work basket all proposes higher requirement with steel wire rope to ABRASION RESISTANCE, rupture pull force and the surface area of steel wire rope.Original steel wire rope, it forms for core thigh 1 and peripheral burst 2 multiply twistings, and as Fig. 2, its shortcoming one is: during use, be that line contacts between steel wire rope and the pulley groove, frictional force is little, easily skids between steel wire rope and the pulley groove, has potential safety hazard; The 2nd,, original steel wire rope, contact area is little between steel wire rope and the pulley groove, and unit are is stressed big, the fracture easy to wear of top layer steel wire.The 3rd,, the density metal coefficient is low, and rupture pull force is little, and service life is short.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of ABRASION RESISTANCE is good, rupture pull force reaches, the big aerial work basket steel wire rope of contact area between steel wire rope and the pulley groove when using.

The purpose of this utility model is achieved in that a kind of aerial work basket steel wire rope, form by a core thigh and a peripheral burst twisting, it is exposed to every described peripheral strand steel wire outer surface and is the face that forges through forging, and is surface contact state closely between the described every steel wire.

The utility model aerial work basket steel wire rope, its advantage is as follows:

The one,, during use, be that face contacts between steel wire rope and the pulley groove, frictional force is big, is difficult for skidding between steel wire rope and the pulley groove, and is safe.

The 2nd,, the steel wire rope surface is through forging, and contact area becomes big between steel wire rope and the pulley groove, and unit are is stressed little, wear-resistant raising, the top layer steel wire is easy fracture not.

The 3rd,, through after forging, the density metal coefficient improves, and it is big that rupture pull force becomes, and improved serviceability, increases the service life.

(4) description of drawings

Fig. 1 is the utility model aerial work basket steel wire rope section structure schematic diagram.

Fig. 2 is original steel wire rope section structure schematic diagram.

Among the figure: core thigh 1, peripheral thigh 2, steel wire 2.1, surperficial 2.1.1.

(5) specific embodiment

Referring to Fig. 1, the aerial work basket steel wire rope that the utility model relates to, formed by a core thigh 1 and peripheral burst 2 twistings, it is exposed to described peripheral strand 2 every steel wire 2.1 outer surperficial 2.1.1 and is the face that forges through forging, and is surface contact state closely between the described every steel wire 2.1.

Described peripheral strand 2 is 4 strands or 6 strands.

The diameter of described steel wire rope is 6-18mm.

During preparation, the steel wire rope that twisting is good forges by swager, and it is exposed to outer surperficial 2.1.1 and goes up the face that forges that forms to make every described peripheral strand 2 steel wire 2.1, is closely surface contact state between every steel wire 2.1.

Claims (3)

1, a kind of aerial work basket steel wire rope, form by a core thigh (1) and peripheral burst (a 2) twisting, it is characterized in that: it is exposed to the every steel wire (2.1) of described peripheral strand (2) outer surface (2.1.1) and is the face that forges through forging, and is surface contact state closely between the described every steel wire (2.1).

2, a kind of aerial work basket steel wire rope according to claim 1 is characterized in that: described peripheral strand (2) are 4 strands or 6 strands.

3, a kind of aerial work basket steel wire rope according to claim 1 and 2, it is characterized in that: the diameter of described steel wire rope is 6-18mm.
