Abstract
The utility model relates to an elevator compensation wire rope that stability is good, including central thigh, the outer circumference package of central thigh is twisted with fingers and is had a plurality of rope strands B, rope strand C and rope strand D, and the wire diameter is greater than wire diameter in central thigh, the rope strand C in rope strand D, the rope strand B, the gap between rope strand C and the rope strand D is filled with anticorrosive plastic, and the rope strand D outside is wrapped up in and is equipped with ceramic fibre layer and anti-looseness cover. The utility model can improve the high temperature resistance and corrosion resistance of the steel wire rope by arranging the ceramic fiber layer and the anticorrosive plastic; meanwhile, the strand with the opposite twisting direction and the anti-loosening sleeve enable the rotating torque directions of different strands in the steel wire rope to be opposite, so that the steel wire rope has the characteristics of micro rotation and even no rotation, and safety accidents caused by the fact that the steel wire rope rotates under tension are reduced.
Description
Technical Field
The utility model relates to a wire rope technical field especially relates to a good elevator compensation wire rope of stability.
Background
The constant up and down motion of the elevator creates a dynamic imbalance, which is usually adjusted using compensating ropes. However, the existing part of the steel wire ropes is pure metal steel wire ropes, so that the steel wire ropes are easy to corrode and age, the service life of the steel wire ropes is shortened, the steel wire ropes can rotate under the action of self tension, the stability is poor, and great potential safety hazards are caused to the use of the elevator.
Disclosure of Invention
The utility model discloses aim at solving prior art's not enough, and provide a good elevator compensation wire rope of stability.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
the compensating steel wire rope for the elevator with good stability comprises a center strand, wherein a plurality of strands B and strands C are wrapped and twisted on the outer circumference of the center strand, the strands B and the strands C are arranged at intervals, a plurality of strands D are wrapped and twisted on the outer circumferences of the strands B and the strands C, the twisting direction of the strands D is opposite to that of the strands B and the strands C, the center strand, the strands B, the strands C and the strands D are all made of twisted steel wires, the diameters of the steel wires in the strands D and B are larger than those of the steel wires in the center strand and the strands C, anticorrosive plastics are filled in gaps among the center strand, the strands B, the strands C and the strands D, a ceramic fiber layer is wrapped on the outer side of the strands D, and an anti-loosening sleeve is arranged on the.
In particular, the anticorrosive plastic is PTFE plastic.
In particular, the anti-loose sleeve is a polyurethane wear-resistant sheath.
The utility model has the advantages that: the utility model can improve the high temperature resistance and corrosion resistance of the steel wire rope by arranging the ceramic fiber layer and the anticorrosive plastic; meanwhile, the strand with the opposite twisting direction and the anti-loosening sleeve enable the rotating torque directions of different strands in the steel wire rope to be opposite, so that the steel wire rope has the characteristics of micro rotation and even no rotation, and safety accidents caused by the fact that the steel wire rope rotates under tension are reduced.

Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1 and 2, an elevator compensating steel wire rope with good stability comprises a central strand 1, wherein a plurality of strands B2 and C3 are wrapped and twisted on the outer circumference of the central strand 1, the strands B2 and C3 are arranged at intervals, a plurality of strands D4 are wrapped and twisted on the outer circumferences of the strands B2 and C3, the twisting direction of the strands D4 is opposite to that of the strands B2 and C3, the central strand 1, the strands B2, the strands C3 and the strands D4 are all made of twisted steel wires, the diameters of the steel wires in the strands D4 and the strands B2 are larger than those in the central strand 1 and the strands C3, corrosion-resistant plastics 5 are filled in gaps among the central strand 1, the strands B2, the strands C3 and the strands D4, a ceramic fiber layer 6 is wrapped on the outer side of the strands D4, and an anti-loosening sleeve 7 is arranged on the outer side of the ceramic fiber layer.
In particular, the corrosion-resistant plastic 5 is a PTFE plastic.
In particular, the anti-loose sleeve 7 is a polyurethane wear-resistant sheath.
In use, a pair of oppositely directed rotational moments is generated due to the opposite lay direction of strand D4 as compared to strand B2. Because the direction of the rotating moment generated by the strand B2 and the strand C3 on the inner side is opposite to the direction of the rotating moment generated by the strand D4 on the outer side, the two rotating forces are mutually counteracted, so that the steel wire rope has the characteristic of micro rotation or even no rotation; the anti-loosening sleeve 7 made of polyurethane can not only ensure that the steel wire rope cannot be loosened in use, but also reduce the abrasion degree of the surface of the steel wire rope; the ceramic fiber layer 6 has excellent corrosion resistance and heat resistance, a first corrosion-resistant protective layer can be provided for the strands, the anticorrosive plastic 5 made of PTFE plastic provides a second corrosion-resistant protective layer for the strands, and the double-layer protective layer prolongs the service life of the steel wire rope.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements made by the method concept and technical solution of the present invention or directly applied to other occasions without improvement are all within the protection scope of the present invention.
