Abstract
The utility model discloses a cable special for a construction elevator. The cable comprises a plurality of conductors with different cross sectional areas. The conductors consist of three large conductors and a small conductor and are all formed by annealed oxygen-free copper wire strands with high-strength fiber ropes as centers. Each conductor is wrapped by a non-woven fabric wrapping layer, an EPR insulation layer and a high-strength filament braid layer successively. The plurality of conductors wrapped by the high-strength filament braid layers are placed vertically in parallel to form a cable core, which is formed in a chlorinated polyethylene rubber outer sheath layer through extrusion. The cable is designed with a reasonable structure. The insulated cable core forms a cable without filling and tape wrapping, and is coated by the chlorinated polyethylene rubber outer sheath layer through extrusion. The cable is excellent in flexibility, tensile strength, twisting resistance, flame retardance, and resistance to oil, UV, thermal aging and weather, and thus is extended in service life.
Description
technical field:
The utility model relates to cable, relates in particular to a kind of construction elevator private cable, is applicable to the construction elevator cable of vertical transport in rated voltage 450/750V and following building machinery.
background technology:
In recent years, along with developing rapidly of national economy, the construction increasing year by year of skyscraper, is also widely used as the construction ladder of skyscraper vertical transport simultaneously, and the terraced cable market prospects of construction matching used with it are boundless.
At present, the quality problems of the cable that construction elevator is used also occur often, and cable is partially short useful life.The subject matter existing is as follows:
1, the operation of construction elevator height is improving constantly, and constructs in terraced running, and due to highly large up and down, very large stress can be gathered in cable inside, is bearing larger pulling force and torsion, the short time inner cable core that will break.This problem is very serious, is also often to occur.
2, construction elevator every day upper and lower (up to tens meters, even hundred meters) hundreds of time bending, in the common short period of cable, just there will be the phenomenon of distortion, bulge, broken skin, impact is used.
3, cable is laid in outdoor and has in oily environment, is often subject to the irradiation of UV sunlight, adds the corrosion to cable cover(ing) of oil that construction elevator equipment leaks outside, and cable jacket will accelerated ageing, and shorten the useful life of cable.
For this problem, designer need to develop and can meet outside mechanical performance and electric property require, and can meet again that pliability is good, the construction elevator cable of tension, anti-torsion, grease proofing, antiultraviolet, heat oxygen aging resistance, weatherability and the performance requirement such as fire-retardant.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of construction elevator private cable, can meet mechanical performance and electric property requirement, can meet again that pliability is good, tension, anti-torsion, grease proofing, antiultraviolet, heat oxygen aging resistance, weatherability and the performance requirement such as fire-retardant.
The technical solution of the utility model is as follows:
Construction elevator private cable, comprise the many conductors that sectional area is different, it is characterized in that: many described conductors are comprised of three large conductors and a little conductor, many conductors all adopt annealing copper free wire centered by high strength fibre rope, to restraint strand formation, many conductors are provided with nonwoven fabrics lapping layer, ethylene propylene rubber insulated layer, high strength fibre silk braid outward successively, parallel the combining of many conductors of coated high strength fibre silk braid put formation cable core, cable core through extrusion moulding in chlorinated polyethylene rubber external sheath layer.
Described construction elevator private cable, is characterized in that: described high strength fibre rope adopts carbon fibre composite or aramid fiber reinforced composite.
Described construction elevator private cable, is characterized in that: the count of described high strength fibre silk braid is not less than 85%.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, conductor adopts the 6th kind of annealed copper conductor, after the first Shu Hecheng strand of annealing copper free wire, then adopts the mode of twisting again forward and reverse stranded with restrainting the strand getting togather in high strength fibre rope, and then overlapping wrapped layer of non-woven fabric outside conductor, prevents that conductor is loose.By the control to copper wire percentage elongation, bundle strand pitch, improve pliability and the tensile strength of cable, reduce the generation of conductor torsional deformation, even disconnected core phenomenon.
2, at insulating barrier, weave the filament that intensity is large, counter-bending, tensile property is good outward, count is not less than 85%, insulation and sheath are isolated, make to there is sliding between insulating barrier and restrictive coating, tension and the anti-torsion ability of cable have effectively been improved, prevent that cable is torn in the process of reversing, and has extended the useful life of cable.
3, insulated wire cores stranding do not fill, band not, directly extrude oversheath, stranding gap is full of tensile strength and the high rubber sheath of elongation at break, can finely must improve pliability, stability, tension and the anti-twisting property of cable, reduce the generation of cable core break phenomenon, extend the useful life of cable.
4, oversheath adopts chlorinated polyethylene rubber sheath material, and it has, and pliability is good, grease proofing, antiultraviolet, heat oxygen aging resistance, weatherability, tensile strength and the excellent properties such as elongation at break is high and fire-retardant, and cable can adapt to all kinds of adverse circumstances.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to Fig. 1:
Construction elevator private cable, comprise the many conductors that sectional area is different, many conductors adopt the 6th kind of soft copper conductor, many conductors are comprised of three large conductors 1 and a little conductor 2, many conductors all adopt annealing copper free wire centered by high strength fibre rope 3, to restraint strand formation, many conductors are provided with nonwoven fabrics lapping layer 4 outward successively, ethylene propylene rubber insulated layer 5, high strength fibre silk braid 6, insulation and sheath are isolated, make to there is sliding between insulating barrier and restrictive coating, tension and the anti-torsion ability of cable have effectively been improved, prevent that cable is torn in the process of reversing, extended the useful life of cable, parallel the combining of many conductors of coated high strength fibre silk braid 6 put formation cable core, cable core through extrusion moulding in chlorinated polyethylene rubber external sheath layer 7, directly extrude, stranding gap is full of tensile strength and the high rubber sheath of elongation at break, can the fine pliability that must improve cable, stability, tension and anti-twisting property, reduce the generation of cable core break phenomenon, extend the useful life of cable.
High strength fibre rope 3 adopts carbon fibre composite or aramid fiber reinforced composite.
The count of high strength fibre silk braid 6 is not less than 85%, and intensity is large, counter-bending, tensile property is good.
