Abstract

The utility model relates to a parallel stranding steel wire rope for an elevator. The parallel stranding steel rope is twisted once by nine interlayer plies and nine outer-layer plies around one central ply core, the nine interlayer plies and the nine outer-layer plies in the steel wire rope are of a parallel stranding structure, a wire contact state is presented between plies of each interlayer ply and the outer-layer ply, the wire contact state is presented between steel wire ropes of the central ply core, each interlayer ply and each outer-layer ply, the steel wire ropes are tightly contacted, and the contact stress is small. The stranding structure of the steel wire rope is compact and stable, the abrasion resistance and the fatigue resistance of the steel wire rope is excellent, the service life of the steel wire rope is long, and the usage requirement of a high-speed elevator can be satisfied.

Description

A kind of elevator Lang lay rope

Technical field

The utility model relates to a kind of elevator Lang lay rope, belongs to the metallic article technical field.

Background technology

Steel wire rope for elevator is generally 6 * 19,8 * 19 ordinary construction steel wire ropes, and there is the twisting fault of construction in such steel wire rope, and the twisting structure is not tight, structural instability, wear-resistant low with fatigue performance, service life is not high, can not satisfy the needs of high-speed elevator operation.

The utility model content

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of elevator Lang lay rope to be provided, the requirement of using to satisfy steel wire rope for high-speed elevator.

The technical solution of the utility model is:

A kind of elevator Lang lay rope, it is made of around a central strand core primary twisting nine internal layer thighs and nine outer layer strand, nine internal layer thighs and nine outer layer strand are the parallel twisting structure in the steel wire rope, be the line contact condition between internal layer thigh and outer layer strand thigh and the thigh, be the line contact condition between central strand core, internal layer thigh and each strand of the outer layer strand steel wire.

Described central strand core is made of 19～26 steel wire twistings, and structure is 19S or 19W or 21Fi or 25Fi or 26WS.

Described internal layer thigh (2) is made of 7～19 steel wire twistings, and structure is 19S or 19W.

Described outer layer strand (3) is made of 19～26 steel wire twistings, and structure is 19S or 19W or 21Fi or 25Fi or 26WS.

The beneficial effects of the utility model:

1, contact between steel wire and the steel wire closely, compact stress is little.

2, twisting wire rope close structure, structure is more stable.

3, steel wire rope is wear-resistant and fatigue performance good, high life.

Description of drawings

Fig. 1 is the utility model elevator Lang lay rope cross section structure schematic diagram.

Among the figure: 1-central strand core, 2-internal layer thigh, 3-outer layer strand.

The specific embodiment

Below in conjunction with accompanying drawing the utility model elevator is described in further detail with Lang lay rope:

Among the figure, it is made of around central strand core 1 primary twisting nine internal layer thighs 2 and nine outer layer strand 3, nine internal layer thighs 2 and nine outer layer strand 3 are the parallel twisting structure in the steel wire rope, be the line contact condition between 3 strands of internal layer thigh 2 and outer layer strand and the thigh, be the line contact condition between central strand core 1, internal layer thigh 2 and outer layer strand 3 each strand steel wires.

Described central strand core 1 is made of 19～26 steel wire twistings, and structure is 19S or 19W or 21Fi or 25Fi or 26WS.

Described internal layer thigh 2 is made of 7～19 steel wire twistings, and structure is 19S or 19W.

Described outer layer strand 3 is made of 19～26 steel wire twistings, and structure is 19S or 19W or 21Fi or 25Fi or 26WS.

Consisted of around a central strand core primary twisting by many internal layer thighs and many outer layer strand, many internal layer thighs and many outer layer strand are the parallel twisting structure in the steel wire rope, be the line contact condition between the thigh of internal layer thigh and outer layer strand and the thigh, be the line contact condition between central strand core, internal layer thigh and each strand of the outer layer strand steel wire.
