Abstract
The utility model relates to a power and signal transmission cable for a lift and a mobile device. The power and signal transmission cable is characterized by comprising an abrasion-proof and twist-resistant ethylene propylene sheath, an aramid fiber braid, a non-woven cloth taped covering, a plurality of strands of copper conductors, twist-resistant ethylene propylene insulating layers coated on the surfaces of the copper conductors and aramid fiber reinforcement cores arranged between the copper conductors. The power and signal transmission cable has the advantages that the problems of twist deformation, swelling, cover tearing and core breaking of the cable are solved, the service time of the product is over fourfold that of the conventional cable, the frequent using safety of the lift is ensured, the using amount of the conventional cable is decreased, material energy is saved, the maintenance cost of a lift manufacturer is lowered, and engineering construction efficiency and safety are improved.
Description
Technical field
The utility model belongs to electric power and signal-transmitting cable, relates in particular to the electric power and the signal-transmitting cable of a kind of lift and mobile device.
Background technology
Present important employings of lift cable YCW type Plastic-sheathed Cable, the flow process of this cable: copper wire is stranded → insulate extrude → spark detection → insulated wire cores stranding is stranded → sheath extrudes → the cable product inspection.This cable uses for a long time and causes the distortion of opening circuit, insulate of cable cover(ing) bulge, conductor more than 3 months.Lift uses and mostly to be common Plastic-sheathed Cable, common Plastic-sheathed Cable after using several months as the lift cable on the lift, can be distorted distortion, bulge, broken skin, core breaks.Building hoist frequently uses, cable lower end excessive fatigue under the effect of twisting resistance and distortion is gradually used so general General Purpose Rubber cable is difficult on the building hoist for a long time.Along with improving constantly of lift height; Requirement to supporting cable is very different; Because in the lift running, very big stress can be gathered in cable inside, when the height of lift greater than 120m [traditional lift is about 70m]; Torsional stress in the cable can be bigger, after traditional cable is used for this type of lift.The frequently disconnected core because torsional stress can not in time eliminate or alleviate.
The utility model content
The utility model is in order to overcome deficiency of the prior art, the electric power and the signal-transmitting cable of a kind of lift and mobile device to be provided, solving lift cable high frequency time and move back and forth the problem that causes cable to be distorted distortion, bulge, to break skin, disconnected core.
The utility model is for realizing above-mentioned purpose; Realize through following technical scheme; The electric power of a kind of lift and mobile device and signal-transmitting cable is characterized in that: comprise successively wear-resisting twist-resistant type second third sheath, aramid fiber braid, nonwoven fabrics lapping layer, the multiply copper conductor that connects and be coated on twist-resistant type second third insulating barrier on copper conductor surface and place the aramid fiber strengthening core between the multiply copper conductor.
The filament diameter 0.2mm of said copper conductor, said copper conductor are anaerobic soft copper wire material, the percentage elongation of said copper wire＞20%, and percentage elongation >=15%, the stranded lay ratio of said multiply copper conductor is 12.
Beneficial effect: the torsional deformation, bulge, broken skin, the disconnected core that solve cable; Product service time is more than 4 times of former cable; Guarantee the frequent safety of using of lift; Reduce the usage quantity of former cable, the economical with materials energy and the maintenance cost that reduces lift producer, the efficiency of construction and the safety of raising engineering.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with preferred embodiment; Details are as follows to the embodiment that provides according to the utility model: see accompanying drawing for details; The electric power of a kind of lift and mobile device and signal-transmitting cable comprise successively the wear-resisting twist-resistant type second that connects third sheath 1, aramid fiber braid 2, nonwoven fabrics lapping layer 3, multiply copper conductor 4 and are coated on twist-resistant type second third insulating barrier 5 on copper conductor surface and place the aramid fiber strengthening core 6 between the multiply copper conductor.The filament diameter 0.2mm of said copper conductor, said copper conductor are anaerobic soft copper wire material, the percentage elongation of said copper wire＞20%, and percentage elongation >=15%, the stranded lay ratio of said multiply copper conductor is 12.
Adopt special conductor structure, strengthen the pliability of conductor; Select high strength insulation and sheath ethylene-propylene rubber material for use, add the aramid fiber material of stretching resistance in the cable, improve the whole pulling force of cable, guarantee that conductor does not break off; Weave aramid layers behind the stranding; Prevent to insulate bulge and special manufacture craft (like rational twisting pitch; Select the stranding equipment of band back twist for use, guarantee the even tension of each insulation), the intensity of increase cable; Satisfy the frequent requirement of using of domestic large-scale lifter apparatus, avoid occurring torsional deformation, bulge, broken skin, disconnected core phenomenon.The conductor filament diameter is selected the anaerobic soft copper silk of 0.2mm for use, and the percentage elongation of copper wire is controlled at more than 20%, and GB/3953 requires percentage elongation to be not less than 15%, improves the whole pliability of conductor, and the stranded lay ratio of conductor guarantees the stability of conductor 12.When producing conductor that per share tension adjustment is even, prevent to cause each strand of conductor unbalance stress because of the tension force inequality.
Aramid fiber is that du pont company is developed, and the material tough and hard wear resistant, tempers toughness with gentleness, and has superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, premium properties such as in light weight; Its intensity is 5～6 times of steel wire, and modulus is steel wire or glass fiber 2～3 times, and toughness is 2 times of steel wire; And weight is merely about 1/5 of steel wire; Under the temperature of 560 degree, do not decompose, do not melt.It has good insulation performance property and ageing resistace, has very long life cycle.Selecting aramid fiber for use is the tensile materials of cable, can guarantee the stability and the service time of cable.Low temperature resistant-40 ℃ of cable.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
