Abstract
The invention relates to a compaction-strand steel wire rope for an elevator, consisting of an outer-layer strand and a central strand. The outer-layer strand consists of outer-layer steel wires and inner-layer steel wires which are in staggered arrangement along the circumference direction. The outer-layer strand consists of eight strands, and each strand consists of nine outer-layer steel wires, nine inner-layer steel wires and one central steel wire, wherein each outer-layer steel wire and the central steel wire have the same diameter and are thick steel wires, and the diameter of each inner-layer steel wires is much less than that of each outer-layer steel wires and the central steel wire. In the surface contact steel wire rope, the compression ratio of the outer-layer strand is 11.7 percent, thereby the cross sectional area of the steel wire rope is improved by 10 percent, the breaking force of the whole steel rope is improved by 9.5 percent, the steel wire rope after compaction is compact in structure and uniform in thickness, and the service life of the product is multipled.
Description
Technical Field
The patent relates to a steel wire rope with a novel structure, which is suitable for a high-speed and special elevator car traction main transmission lifting mechanism.
Background
At present, steel wire ropes adopted by an elevator car traction main transmission lifting mechanism are all composed of outer layer strands, inner layer strands and central strands or outer layer strands and hemp core rope cores, wherein the outer layer strands are generally in wire contact structures of Xilu type or Walin type and are formed by twisting round steel wires with different diameters.
When the elevator is used, the steel wire rope, the traction wheel, the guide wheel, the car top wheel and the like form lifting transmission to drive the elevator car to lift.
Because the elevator frequently goes up and down to use for the steel wire of wire rope outer layer strand easily wears out, causes disconnected silk and disconnected strand, shortens wire rope's life, and brings harm to elevator security.
Disclosure of Invention
The invention aims to provide a compacted strand steel wire rope for an elevator, which solves the problems that the common steel wire rope has broken wires and strands and the service life of the steel wire rope is shortened due to the fact that steel wires of outer strands of the steel wire rope are easy to wear.
The purpose of the invention is realized by the following technical scheme:
the problem to be solved by the invention is to provide a compacted steel wire rope suitable for high-speed or special elevators.
In order to solve the problems, the following technical scheme is adopted:
a compacted strand steel wire rope for an elevator is composed of an outer strand and a central strand, wherein each strand of the outer strand is compacted and then formed, the outer steel wire, the inner steel wire and the central steel wire are rolled and drawn into special-shaped regular steel wires through a die in a round shape, namely, contact surfaces between the outer steel wire, the inner steel wire and the central steel wire are mutually matched to form a compacted strand, the central strand is composed of three strands, and each central strand is formed by twisting hemp core filaments.
The outer ply has 8 plies.
The outer layer steel wire and the inner layer steel wire are respectively 9.
The central strand is a hemp core rope core and consists of three strands, and each strand is provided with 5-9 hard sisal hemp according to the different diameters of the steel wire ropes and is twisted into the hemp core rope core.
The outer layer strand is formed by adopting a rolling or die drawing forming process, so that the steel wire rope is knotted to form the surface contact steel wire rope.
By adopting the scheme, the method has the following advantages:
because the face contact wire rope of this patent makes outer strand compressibility 11.7%, makes the cross-sectional area of rope improve 10%, and wire rope's whole rope breaking force improves 9.5%, and the wire rope strand structure is inseparable after the compaction, and the poker is even to increase product life by multiples.
Drawings
The invention is explained in more detail below with reference to the figures and examples.
Fig. 1 is a structural view of a compacted strand wire rope for an elevator.
In the figure: 1. an outer layer strand; 2. a central strand; 11. an outer layer steel wire; 12. an inner layer steel wire; 13. a central steel wire.
Detailed Description
As shown in the attached figure 1, the compacted strand steel wire rope for the elevator consists of an outer strand 1 and a central strand 2, wherein each strand of the outer strand 1 is compacted and then molded, the outer layer steel wire 11, the inner layer steel wire 12 and the central steel wire 13 are round, rolled and die-drawn into special-shaped regular steel wires, namely, contact surfaces between the steel wires are mutually matched to form the compacted strand, the central strand 2 consists of three strands, and each central strand 2 is formed by twisting hard sisal hemp.
The outer layer strand 1 has 8 strands.
The number of the outer layer steel wires 11 and the number of the inner layer steel wires 12 are respectively 9.
The central strand 2 is a hemp core rope core and is composed of three strands, and each strand is provided with 5-9 hard sisal hemp according to the different diameters of the steel wire ropes and is twisted into the hemp core rope core.
The outer layer strand 1 is formed by adopting a rolling or die drawing forming process, so that the steel wire rope is knotted to form a surface contact steel wire rope. Or,
the outer layer strand 2 is formed by compacting and then stranding.
Claims (4)
1. A steel wire rope of a compacted strand for an elevator is composed of an outer strand and a central strand, and is characterized in that the outer strand is provided with 8 strands, each strand is compacted and then molded, and an outer steel wire, an inner steel wire and the central steel wire are rolled and drawn into special-shaped regular steel wires by a round roller, namely, contact surfaces between the steel wires are mutually matched to form the compacted strand; the central strand consists of three strands, each central strand is formed by twisting hemp core filaments, and each strand is provided with 5-9 hard sisal hemp according to different diameters of the steel wire rope and is twisted into a hemp core rope core.
2. The compacted strand steel cord for an elevator according to claim 1, wherein the outer layer steel wires and the inner layer steel wires are 9 steel wires, respectively.
3. The compacted strand wire rope for elevators according to claim 1, wherein the outer layer strands are formed by a roll or die forming process such that the wire rope knots form a surface contact wire rope.
4. The compacted strand steel cord for elevators according to claim 1, wherein the outer layer strands are formed by stranding compacted strands.
