Abstract
The utility model provides a synthesizing distorting resistant reel cable which can prevent from being damaged by external mechanical force and has small radius and excellent properties of warping strength, bending resisting, tensile, signal transmission, oil resisting and insulation. The cable is provided with a dynamic insulating line core, a neutral line core, a grounding wire core, a shielding signal control line core, and a cable core formed by a steel wire strengthening heterotype filling core. The cable core is covered by a protecting layer via extruding high flexible wear-resisting polyurethane. The insulating line core is formed by extruding high flexible wear-resisting polyurethane onto a stranded copper conductor. The steel wire strengthening heterotype filling core is formed by extruding high flexible wear-resisting polyurethane onto a stranded steel wire conductor.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of comprehensive warp resistance drum cable with electric power transfer and control signal system.
Background technology
Along with the power of mobile device increases the also corresponding lengthening in cross section of the service cable that requires, thereby cable weight and installation length further strengthen; The traditional power supply system of sliding contact line of former employing be not suitable in the application of the plant equipment of similar operating modes such as harbor portal crane, container crane, ship loader, derrick crane.The crane in the whole world about 90% adopts the cable drum power supply at present, and volume payout smoothness so that providing continuously of electric power and control information to be provided, was kept the normal operation of equipment when its advantage was the equipment walking.Increase with cable length and crane speed requires cable intensity higher, flexible better in addition; The increase of cable intensity means that cable size, weight will strengthen, and the cable drum size strengthens, production cost increases thereby cause.
In recent years, along with the distance that hoisting machinery need be walked is farther, so that the internal layer of reel differs 3 times even bigger to outer field winding radius, and its constant moment output has proposed higher stretching resistance requirement to cable.Because under the condition that satisfies outer coil of cable power taking requirement, because coiling moment approximately constant, so the tension force that the internal layer cable will bear can be bigger more than 3 times than skin, for embedded cable or the little cable of carrying tension force, causes damage easily.Find that in the coiler device actual motion cable is not to be wrapped on the reel in good orderly in running, therefore be necessary its supporting cable product is carried out technological improvement.When reel batched cable, the cable of back may be pushed down by the cable of front.And when discharging cable, cable overlaps each other, and produces very big additional force, even feasible coupling device skids, cable also can't in time discharge, and may cause cable stressed excessive, until breaking.
Summary of the invention
The utility model is in order to overcome the deficiencies in the prior art, provide that strong, the anti-bending radius of a kind of anti-circumnutating property is little, tension, anti-mechanical external force damage, wear-resisting wiping, signal transmission performance power is strong, oil resistant is dirty, good insulation preformance, comprehensive warp resistance drum cable.
The purpose of this utility model is achieved in that a kind of comprehensive warp resistance drum cable, this cable is provided with the cable core that power insulated wire cores, neutral core and ground connection core, shielding control signal core, steel wire are strengthened special-shaped filled core stranding, extrudes outer jacket by high flexibility abrasion resistant polyurethane squash type on the cable core.
Described insulated wire cores constitutes by extruding high flexibility abrasion resistant polyurethane insulating barrier on the tough copper wire conductor of multiply.
Described steel wire is strengthened special-shaped filled core and is extruded high flexibility abrasion resistant polyurethane insulating barrier by the steel wire strand stranded conductor and become different form.
The utility model inside when cable design has adopted steel wire to strengthen special-shaped filled core, not only stopped cable core at volume, to let slip in the journey mutual extrusion dislocation loosening, and strengthened tensile property; Adopt new material, make product be matched in the reel system and use, will make that reel manufacturing system size is littler, cost is lower, and reduce, range ability long frictional force big problem heavier because of cable, so that providing continuously of electric power and control information to be provided, keep the normal operation of equipment.
Beneficial effect: the utility model is rational in infrastructure simple, manufacture easily, conductor adopts by extruding the power insulated wire cores that the polyurethane insulating layer constitutes on the tough copper wire conductor of multiply, steel wire is strengthened special-shaped filled core, shielding control signal core stranding, squash type extrudes the polyurethane outer jacket on the cable core, the not loosening mutually extruding of the cable core of the reel system cable in service that makes, and it is strong to have anti-circumnutating property, anti-bending radius is little, signal transmission performance power is strong, tension, anti-mechanical external force damage, wear-resisting wiping, the oil resistant dirt, good insulation preformance, anti-electromagnetic interference is suitable for power supply system of sliding contact line at harbor portal crane, container crane, ship loader, the application adapted of the heavy duty equipment of similar operating mode such as derrick crane.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: the tough copper wire conductor of 1 multiply, 2 polyurethane insulating layers, 3 steel wires are strengthened special-shaped filled core, 4 shielding control signal cores, 5 polyurethane outer jackets.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in drawings: a kind of comprehensive warp resistance drum cable constitutes the power insulated wire cores by extruding polyurethane insulating layer 2 on the tough copper wire conductor 1 of multiply.Strengthen special-shaped filled core 3 with five power insulated wire cores, shielding control signal core 4 and steel wire and be twisted into cable core, extrude polyurethane outer jacket 5.
