Abstract

The invention discloses a double-compaction-strand steel wire rope provided with a mixed steel core and used for an elevator. The double-compaction-strand steel wire rope provided with the mixed steel core and used for the elevator comprises a fiber core, nine inner-layered strands and nine outer-layered strands, wherein the fiber core is twisted by the nine inner-layered strands symmetrically to form a mixed rope core; the mixed rope core is twisted by the nine outer-layered strands symmetrically; each outer-layered strand is formed by twisting a center wire by using nine outer-layered heavy steel wires and nine inner-layered thin steel wires in a sealing mode by extrusion production; steel wires in each outer-layered strand are in face contact with one another; each inner-layered strand is formed by twisting a center steel wire by six steel wires symmetrically; and the strands of the steel wire rope are combined and compacted, and are in face contact with one another. The steel wire rope with the structure has ultra-high wear resistance and ultra-high bearing capacity; and moreover, an oil storage function in the rope core of the steel wire rope is guaranteed.

Description

A kind of elevator is with mixing the two compaction-strand steel wire ropes of steel core

Technical field

The present invention relates to a kind of steel wire rope for elevator, relate in particular to a kind of elevator with mixing the two compaction-strand steel wire ropes of steel core.

Background technology

At present, at elevator industry, along with the height of floor rises, the speed of service of elevator is accelerated gradually, also more and more higher to the requirement of steel wire rope, the elevator that some load-carrying is large, the speed of service is fast, require bearing capacity and the anti-wear performance of steel wire rope all will get well, although and the diameter that increases steel wire rope can improve bearing capacity and the anti-wear performance of steel wire rope, improved to a great extent the operating cost of elevator, wasted material.

Summary of the invention

The object of the present invention is to provide a kind of elevator with mixing the two compaction-strand steel wire ropes of steel core, it has the advantages that bearing capacity is good and anti-wear performance is good, to solve the problems referred to above that in prior art, steel wire rope for elevator exists.

For reaching this object, the present invention by the following technical solutions:

A kind of elevator is with mixing steel core pair compaction-strand steel wire ropes, and it comprises 1 fibre core, 9 internal layer thighs and 9 outer layer strand, and the symmetrical bag of described 9 internal layer thighs is twisted with the fingers fibre core and formed mixing wire rope core, and the symmetrical bag of described 9 outer layer strand is twisted with the fingers outside described mixing wire rope core.

Especially, described outer layer strand is to be Xi Lushi and to be produced through extruding by outer 9 thick wires, 1 central hair of 9 finer wire bags sth. made by twisting of internal layer, and in outer layer strand, steel wire is surface contact state.

Especially, described mixing wire rope core is by 9 sub-thread bags, to twist with the fingers a fibre core twisting to form, and its each sub-thread is by 6 steel wires, to wrap symmetrically sth. made by twisting core wire twisting to form.

Especially, after described steel wire rope stranding, again through overcompaction, between strand wire and thigh, be surface contact state.

Especially, described outer layer strand is any of 1 × K17S, 1 × K19W, 1 × K21F, 1 × K25F.

Beneficial effect of the present invention is, compared with prior art described elevator is formed by 9 outer layer strand bags sth. made by twisting mixing wire rope core twistings with mixing the two compaction-strand steel wire ropes of steel core, each outer layer strand is to be Xi Lushi and to be produced through extruding by outer 9 thick wires, 1 central hair of 9 finer wire bags sth. made by twisting of internal layer, and in outer layer strand, steel wire is surface contact state.Mixing wire rope core is by 9 sub-thread bags, to twist with the fingers a fibre core twisting to form, and its each sub-thread is by 6 steel wires, to wrap symmetrically sth. made by twisting core wire twisting to form.After steel wire rope stranding, again through overcompaction, between strand wire and thigh, being surface contact state. the steel wire rope of this structure has the anti-wear performance of superelevation, and the bearing capacity of superelevation guarantees again the oil storage function in wire rope core simultaneously.Contrast the steel wire rope for elevator of same diameter and strength grade in the market, this structure steel wire rope bearing capacity improves 25%, and anti-wear performance improves nearly 25%.

The specific embodiment

Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.

Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of elevator is with mixing the two compaction-strand steel wire ropes of steel core, it comprises a fibre core 1, nine internal layer thighs 2 and nine outer layer strand 3, the symmetrical bag of described nine internal layer thighs 2 is twisted with the fingers fibre core 1 and is formed mixing wire rope core, and the symmetrical bag of described nine outer layer strand 3 is twisted with the fingers outside described mixing wire rope core.

Described outer layer strand 3 is to be Xi Lushi and to be produced through extruding by outer 9 thick wires, 1 central hair of 9 finer wire bags sth. made by twisting of internal layer, and the interior steel wire of outer layer strand 3 is surface contact state.

Described internal layer thigh 2 is by 6 steel wires, to wrap symmetrically sth. made by twisting core wire twisting to form.

After described steel wire rope stranding, through forging, 3 of outer layer strand are surface contact state.

Above-mentioned elevator has super-high wear-resistant performance with mixing the two compaction-strand steel wire ropes of steel core, and the bearing capacity of superelevation, guarantees again the oil storage function in wire rope core simultaneously.Contrast the steel wire rope for elevator of same diameter and strength grade in the market, this structure steel wire rope bearing capacity improves 25%, and anti-wear performance improves nearly 25%.
