Abstract
A strand-compacted wire rope for elevator use comprises external strands and central strands and is characterized in that the external strands are formed after compacting, the external steel wires, internal steel wires and central steel wires form a compacted strand by changing the circular cross-sections into special-shaped cross-sections to form mutually fit surfaces through rolling and die drawing, and each of three central strands is spun with hemp-core filaments. Since the external strands of the facial contacted wire rope are compressed by 11.7%, the cross-sectional area of the wire rope increases by 10%, and aggregate breaking force of the wire rope increases by 9.5 %. After being compacted, the wire rope has a tight structure and even and smooth surface, and the service lifetime of the wire rope is multiplied.
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, a lifting transmission mechanism is formed by a steel wire rope, a traction wheel, a guide wheel, a car top wheel and the like 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.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a compaction thigh wire rope for elevator solves wire rope commonly used because the outer thigh steel wire of wire rope easily wears and teares, causes disconnected silk and disconnected thigh, shortens wire rope's life's problem.
The utility model aims at realizing through 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 molded, the outer steel wire, the inner steel wire and the central steel wire are rolled and drawn into special-shaped sections through circular sections, namely contact surfaces between the outer steel wire, the inner steel wire and the central steel wire are mutually matched to form compacted strands, 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 present invention will be described in further detail with reference to the accompanying drawings 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 formed by rolling and die drawing circular cross sections into special-shaped cross sections, namely, contact surfaces between the outer layer steel wire and the central steel wire are mutually matched to form compacted strands, 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 (5)
1. The compacted strand steel wire rope for the elevator is characterized in that each strand of the outer strand is compacted and then formed, contact surfaces of the outer layer steel wire, the inner layer steel wire and the central steel wire are mutually matched to form compacted strands, each central strand consists of three strands, and each central strand is formed by twisting hemp core filaments.
2. The compacted strand steel cord for elevators according to claim 1, wherein the outer layer strand has 8 strands.
3. 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.
4. The compacted strand steel wire rope for the elevator as claimed in claim 1, wherein the central strand 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 diameter of the steel wire rope and twisted into the hemp core rope core.
5. 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.
