The invention discloses a wire rope left-hand twisting structure for a non-rotating hanging basket, which comprises a complete wire rope consisting of a plurality of single-stranded steel wires wrapped with hemp cores, wherein the single-stranded steel wires comprise outer-layer wires, second-layer wires, first-layer wires and central wires, the outer-layer wires are wrapped outside the second-layer wires, the second-layer wires are wrapped outside the first-layer wires, the first-layer wires are wrapped outside the central wires, and the wire rope left-hand twisting structure is characterized in that the wire rope adopts a clockwise left-hand twisting structure. The tightness of the hanging basket steel wire rope with the left-twist structure is tighter than that of the hanging basket steel wire rope with the right-twist structure, the internal stress is eliminated thoroughly, the strand-to-strand loosening phenomenon cannot occur in the using process, the normal operation of the hanging basket is effectively ensured, the left-twist steel wire rope is higher in wear resistance, better in tightness, lower in elongation and not easy to cause the phenomenon of slipping caused by diameter reduction of the steel wire rope.
Description
Technical Field
The invention relates to the technical field of steel wire rope manufacturing, in particular to a left-twisting structure of a steel wire rope for a non-rotating hanging basket.
Background
1. The steel wire rope is lifted mainly by the extrusion friction force of the steel wire rope in the process of overhead operation, so that the steel wire rope rotates, and when the steel wire rope rotates, the steel wire rope in the air is easy to cause coiling and knot tying or the steel wire rope is lifted, so that potential safety hazards are caused.
2. The tightness of the hanging basket steel wire rope with the right-twist structure is not tight enough, the inner guiding force is eliminated, the phenomenon that the steel wire rope strands are loosened and separated due to the extrusion effect of the external force under the condition of the tightness not tight enough, the phenomenon that the hanging basket steel wire rope is locked in the using process can occur, and potential safety hazards can be brought to hanging basket lifting operation.
3. Because the right-twisted steel wire rope is not tight enough, strands can be loosened and lifted by external force in the using process, the side length can enable the diameter of the steel wire rope to be thinned when the steel wire rope is stretched, the phenomenon of slipping between the steel wire rope and a guide wheel when a hanging basket is used can be caused, and the steel wire rope is unstable in the lifting operation.
4. The application number, CN202021459343.1, has already disclosed a no-twist steel cable, in which the clockwise left-twist structure of the steel cable is not disclosed, and the present invention is a new technical solution made on the basis of this.
Disclosure of Invention
The invention relates to a left twisting structure of a steel wire rope for a non-rotating hanging basket, which is used for solving the defects of the prior art mentioned in the background technology.
The specific technical scheme is as follows: irrotational wire rope left side twists with fingers structure for hanging flower basket includes the complete wire rope of constituteing by a plurality of single strand steel wire parcel numb core, the single strand steel wire is including outer silk, second floor silk, first floor silk, center wire, outer silk parcel is in the second floor silk outside, second floor silk parcel is in the first floor silk outside, first floor silk parcel is in the center wire outside, wire rope adopts clockwise left side to twist with fingers the fingers structure.
Advantageous effects of the invention
1. After twisting with fingers the structure on a left side, wire rope twisted with fingers to receive the revolving force opposite with the friction extrusion when self upward movement time hanging flower basket atress, make operation wire rope irrotational, can not cause to roll up knot and detain, the atress is even, can not break when the steady use of operation simultaneously, even broken silk, can not the perk yet, still is laying down in the primary importance, is unlikely to fish tail rope sheave or reel, does not influence the normal work of other steel wires, uses safelyr, reliable.
2. The tightness of the steel wire rope of the hanging basket with the left-twist structure is tighter than that of the steel wire rope of the hanging basket with the right-twist structure, the internal guiding force is eliminated thoroughly, the strand-strand relaxation phenomenon cannot occur in the using process, and the normal operation of the hanging basket is effectively guaranteed.
3. The left-twisted steel wire rope has high wear resistance, high tightness and low elongation, and the phenomenon of skidding caused by the diameter reduction of the steel wire rope is not easy to cause.
Drawings
FIG. 1 is a schematic diagram of the left lay configuration of the steel cord of the present invention;
fig. 2 is a schematic view of the internal structure of the steel cord of the present invention.
In the figure; 1 second layer of wire, 2 central wire, 3 hemp core, 4 first layer of wire, 5 outer layer of wire and 6 steel wire rope.
Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the examples listed.
As shown in figures 1-2, the invention discloses a left twisting structure of a steel wire rope for a non-rotating hanging basket, which comprises a complete steel wire rope formed by a plurality of single-stranded steel wires wrapping a hemp core, wherein each single-stranded steel wire comprises an outer layer wire 5, a second layer wire 1, a first layer wire 4 and a central wire 2, the outer layer wire 5 wraps the outer side of the second layer wire 1, the second layer wire 1 wraps the outer side of the first layer wire 4, the first layer wire 1 wraps the outer side of the central wire 2, the specific structure is shown in figure 2, the steel wire rope 6 adopts a clockwise left twisting structure, the specific left twisting structure is shown in figure 1, after the left twisting structure is adopted, because the twisting direction of the steel wire rope is opposite to the rotating force of frictional extrusion when the steel wire rope is stressed during self upward movement, the steel wire rope is not rotated, the steel wire rope cannot be coiled and buckled, the stress is uniform, and the steel wire rope cannot be broken even when the steel wire rope runs stably, even if the steel wire rope is broken, the steel wire rope can not be tilted and still can be laid at the original position, so that the rope wheel or the winding drum can not be scratched, the normal work of other steel wires can not be influenced, and the use is safer and more reliable. The tightness of the hanging basket steel wire rope with the left-hand twisting structure is tighter than that of the hanging basket steel wire rope with the right-hand twisting structure, the internal guiding force is eliminated thoroughly, the strand-strand loosening phenomenon cannot occur in the using process, the normal operation of the hanging basket is effectively guaranteed, the left-hand twisting steel wire rope is high in wear resistance, good in tightness, low in elongation and not prone to causing the phenomenon that the diameter of the steel wire rope is reduced and slipping is caused.
According to the invention, a plurality of groups of left-twisted steel wire ropes with different diameters are tested, the breaking tension of the left-twisted steel wire ropes is increased by 2% by comparing the experimental data with the steel wire ropes with the same structure of the right-twisted structure rope in YB/T4575-2016, and the experimental data shows that the minimum torsion coefficient is increased by 5% -7% because the left-twisted structure is twisted clockwise compared with the traditional right structure.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the invention, and the purpose of the present invention is to enable those skilled in the art to understand the contents of the invention and to implement the invention, and not to limit the protection scope of the invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
