Description

Steel wire rope for elevator

Technical Field

The utility model mainly relates to a wire rope field especially relates to a wire rope for elevator.

Background

Because the elevator device is in a wet working state for a long time, the mechanical property of the elevator steel wire rope is reduced in the long-term use process, the diameter of the steel wire is thinned, and the space between strands is loosened, so that brittle fracture occurs. This fracture is an "avalanche" fracture, which is more dangerous than a normal wire break or wear.

The published Chinese invention patent, application number CN201611018637.9, patent name: the utility model provides a special wire rope is used to elevator, application date: 20161118, the invention relates to a special steel wire rope for an elevator, which comprises an external flat fixing device, wherein steel wire rope devices are transversely and uniformly distributed in the external flat fixing device, each steel wire rope device comprises an inner layer core wire group and an outer layer core wire group, six outer layer core wire groups are uniformly distributed outside the inner layer core wire group, the inner layer core wire group comprises an inner core and eight outer inner cores uniformly distributed outside the inner core, the outer layer core wire group comprises an outer core and eight secondary outer cores uniformly distributed outside the outer core, the inner layer core wire group and the outer layer core wire group, the inner core and the outer core and the secondary outer cores are tightly abutted with each other, an anti-skid layer is coated outside the outer layer core wire group, and the anti-skid layer is connected with the external flat fixing device. The advantages are that: the steel wire rope for the elevator is formed by pressing the outer fixed flat device by polyurethane and the steel wire rope device arranged in the outer fixed flat device, so that the steel wire rope for the elevator has excellent wear resistance, excellent shock absorption and anti-skid performance.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the present invention provides a steel wire rope for an elevator, which comprises a rope core 1, inner layer rope strands 2 and outer layer rope strands 3 sequentially arranged from inside to outside, wherein a plurality of inner layer rope strands 2 and outer layer rope strands 3 are provided, the inner layer rope strands 2 are spirally twisted around the rope core 1, the outer layer rope strands 3 are spirally twisted around notches between the inner layer rope strands 2,

the number of the inner layer strands 2 and the number of the outer layer strands 3 are the same, and the inner layer strands 2 and the outer layer strands 3 are in parallel contact.

Preferably, the ratio of the diameter of the inner layer strands 2 to the diameter of the outer layer strands 3 is 1: 2.

preferably, the rope core 1 is made of No. 50-65 high-quality carbon steel.

Preferably, No. 1 steel wires are used for the inner layer strands 2 and the outer layer strands 3.

Preferably, bristle brush is used for uniformly and thinly coating the surface of the outer layer strand 3 once against the running direction of the steel wire rope with special ET diluted elevator steel wire rope grease.

The utility model has the advantages that: the inner layer and the outer layer are the same in quantity, but different in diameter, and the outer layer is embedded in the inner layer and the outer layer of the notch, and the lay lengths of the multi-layer steel wires are equal, so that the structure is compact and firm, and the uncoiling is not easy. The wear resistance of the outer layer thick steel wire is improved, the flexibility of the inner layer thin steel wire is improved, and mutual sliding in bending is facilitated, so that the flexibility and the service life of the steel wire rope are improved; the steel wires between the layers are in parallel line contact, the fatigue resistance of the steel wire rope is good, the abrasion resistance between the inner parts of the steel wires is good, the contact area is increased, and the contact stress is reduced.
