Abstract
The invention discloses a flexible signal cable for a huge crane. The flexible signal cable consists of a conductor, an insulating layer, a wire core, a cable core, a stuffing stem, an internal jacket, an external jacket, a main wire core, a grounding wire core and a communication wire core; the insulating layer is extruded on the conductor to form the wire core; a circle of the wire core is tightly arranged at the periphery of the stuffing stem to form the cable core; the internal jacket is extruded at the periphery of the cable core; and the external jacket is extruded at the periphery of the internal jacket. The invention provides the flexible signal cable for the huge crane, which has the advantages of good electrical conductivity, strong signal transmission capability, strong flexibility, capability of high-speed repeated movement and long service; and in particular, the flexible signal cable for the huge crane is suitable for the equipment such as the large crane which is used for rapidly moving articles upward and downwards or leftwards and rightwards when elements are lifted, needs powerful power support and needs to transmit a large amount of information with the outside.
Description
Technical field
The present invention relates to technical field of electric wires and cables, particularly goliath cable technology field is specially a kind of goliath with the anti-signal cable that circumnutates.
Background technology
At present, large scale hoisting machinery not only need obtain powerful electric power support but also need with the external world a large amount of communications is arranged in running.Goliath lifting during element fast up and down or the move left and right article, need powerful electric power support, need again to transmit bulk information make object accurately fast lifting put in place.Traditional power cable can only provide electric power that communication can not be provided simultaneously, more can not do with equipment the movement of quick high frequency time.Traditional cable also exists the shortcoming such as difficult installs, cost is large, cable is yielding and the life-span is short.Along with the fast development to the high-tech direction such as modern crane tool, the tonnage of lifting increases gradually, and gait of march is constantly accelerated, and needs cable that the fabulous anti-performance and make at a high speed the repeatedly performance of motion of circumnutating is arranged.Therefore, traditional cable oneself can not satisfy above-mentioned needs far away.
Summary of the invention
The purpose of this invention is to provide a kind of good conductivity, strong, anti-the circumnutating property of message transmission capability strong, can make at a high speed repeatedly the goliath of motion and long service life with the anti-signal cable that circumnutates, when the lifting element, need to be specially adapted to fast up and down or move left and right article and electric power support that not only need be powerful but also the equipment such as the goliath use of a large amount of communications need be arranged with the external world.
Technical scheme of the present invention is: a kind of goliath with anti-circumnutate signal cable by conductor, insulating barrier, core, cable core, filling stem stem, inner sheath, oversheath, master core, core and communication core consist of.The extruded insulation layer forms core on conductor.Filling the peripheral close-packed arrays one astragal core composition of stem stem cable core.Extrude inner sheath in the cable core periphery.Extrude oversheath in the inner sheath periphery.
Described conductor all adopts multiply to have the multiple strand combining structure of the thin copper wire of high conductivity coating.
Described core by master core, core and communication core form.
Described filling stem stem is selected the high strength flexible material, and fracture strength is not less than 500N.
Described high strength flexible material selection aramid fiber material.
Described inner/outer sheath is all selected has excellent fire-retardant, high strength, high-wearing feature, high anti-circumnutating property, little, the lightweight rubber material of external diameter.
A kind of in described rubber material selection ethylene-propylene rubber, neoprene rubber or the chlorosulfonated polyethylene rubber material.
Advantage of the present invention provided a kind of good conductivity, strong, anti-the circumnutating property of message transmission capability strong, can do that high speed is moved repeatedly and the goliath of long service life with the anti-signal cable that circumnutates.It need during element fast up and down or move left and right article and not only need powerful electric power support but also need have the equipment such as goliath of a large amount of communications to use with the external world in lifting to be specially adapted to.
Description of drawings

Fig. 1 is goliath with the cross section structure schematic diagram of the anti-signal cable that circumnutates.
Among the figure: 1, conductor; 2, insulating barrier; 3, core; 4, cable core; 5, fill stem stem; 6, inner sheath; 7, oversheath; 8, master core; 9, core; 10, communication core.
Embodiment
Embodiment as shown in Figure 1 is as follows: a kind of goliath with anti-circumnutate signal cable by conductor 1, insulating barrier 2, core 3, cable core 4, fill stem stem 5, inner sheath 6, oversheath 7, master core 8, core 9 and communication core 10 consist of.Extruded insulation layer 2 forms core 3 on conductor 1, filling stem stem 5 peripheral close-packed arrays one astragal cores 3 composition cable cores 4, extrudes inner sheath 6 in cable core 4 peripheries, extrudes oversheath 7 in inner sheath 6 peripheries.
Described conductor 1 all adopts multiply to have the multiple strand combining structure of the thin copper wire of high conductivity coating.
Described core 3 by master core 8, core 9 and communication core 10 form.
Described filling stem stem 5 is selected aramid fiber material.
Described inner sheath 6 is selected the ethylene-propylene rubber material.
Described oversheath 7 is selected neoprene rubber material.
