Abstract
The utility model discloses a special belt-shaped extra soft cable for a large-scale gantry crane, belonging to the field of a power cable, and aiming at solving the problems that the existing cable has large bend radius, and the core of a conductor is easy to break and the insulation is damaged. The cable is formed into a twisted copper conductor which is made by twisting a plurality of thin copper wires, the twisting lay ratio of the copper wires is (5-7):1, the twisted copper conductor is externally packed with a plurality of insulating cable cores which consists of a plurality of ethylene propylene rubber insulating layers, each insulating cable core is externally and respectively packed with a cotton yarn weaving layer, a plurality of insulating cable cores are arranged in parallel to form into the cable, and a plurality of hemp ropes are filled into gaps among all insulating cable cores, the cable is externally extruded and packed with a chlorosulfonated polyethylene synthetic rubber inner protecting sleeve, the chlorosulfonated polyethylene synthetic rubber inner protecting sleeve is externally packed with a nylon fiber weaving layer, the coverage rate of the nylon fiber weaving layer is not less than 85%, and the nylon fiber weaving layer is externally extruded and packed with a chlorosulfonated polyethylene synthetic rubber outer protecting sleeve. The belt-shaped extra soft cable meets the requirements of the extra small bend radius, the frequent moving bend and the suspending work for the matched cable required by the large-scale gantry crane.
Description
Technical field
The utility model relates to a kind of power cable, and particularly a kind of large-sized gantry hangs special-purpose banded high flexible cable.
Background technology
Large-sized gantry hangs every day will do a large amount of liftings, reciprocating motion, hang the cable that matches with large-sized gantry, also to be moved continually, be stretched or with less radius bend, this is just had higher requirement to pliability, reliability and the fatigue performance of cable.
On July 30th, 2008, publication number is the Chinese invention patent application of CN101335119, disclose a kind of flexible cable, comprised conductor wire core and the flame retardant insulation that is extruded on the described conductor wire core outer surface, wherein: conductor wire core constitutes by the multiply conductive monofilament is stranded; Every conductive monofilament is made of the aluminium conductor copper clad outer with being coated on aluminium conductor.When this cable hangs on use at large-sized gantry, because the ampacity that needs is bigger, cause the diameter of cable also thicker, cause Cable Bending Radius bigger thereupon, under the operating mode of frequent bending, stretcher strain, phenomenons such as the disconnected core of conductor, damage in insulation, insulation property weaken fast, aging acceleration take place in endurance easily not.
The utility model content
Big for overcoming the bending radius that existing cable exists, the problem of the disconnected core of conductor, damage in insulation takes place easily, the utility model provides a kind of large-sized gantry to hang special-purpose banded high flexible cable, and bending radius is little, has both had intensity preferably, has good flexible again.
For solving above technical problem, a kind of large-sized gantry provided by the utility model hangs special-purpose banded high flexible cable, twisted copper conductors is coated with ethylene propylene rubber insulated layer and constitutes insulated wire cores, many described insulated wire cores formation cable that is arranged side by side, space between each insulated wire cores is filled with the rope made of hemp that is formed by strands, described cable is extruded with the Hypalon inner sheath outward, described Hypalon inner sheath is coated with the nylon fiber braid, and described nylon fiber braid is extruded with the Hypalon oversheath outward.
With respect to prior art, the utility model has been obtained following beneficial effect: thoroughly do away with the edge core formation cable that is arranged side by side more, make cable be flat structure, have less bending radius; Space between each adjacent insulated wire cores adopts the rope made of hemp to fill, and both can guarantee that the insulated wire cores arrangement was smooth, can strengthen the anti-drag force of cable again; Inner sheath is coated with the nylon fiber braid, and the nylon fiber braid is extruded with oversheath outward, makes whole cable form one, makes cable have intensity preferably.
As improvement of the present utility model, described each insulated wire cores is coated with cotton braid outward respectively.Insulated wire cores coats cotton braid outward, mechanical strength that can the reinforced insulation core, and insulated wire cores protected.
As preferred version of the present utility model, described twisted copper conductors is by many stranded the forming of thin copper wire, and the stranded lay ratio of copper wire is (5～7): 1.
As preferred version of the present utility model, the coverage rate of described nylon fiber braid is not less than 85%.
Description of drawings
Fig. 1 hangs the structural representation of special-purpose banded high flexible cable for the utility model large-sized gantry.
Among the figure: 1 twisted copper conductors, 2 ethylene propylene rubber insulated layers, 3 cotton braids, 4 ropes made of hemp, 5 Hypalon inner sheaths, 6 nylon fiber braids, 7 Hypalon oversheaths.
Embodiment
As shown in Figure 1, large-sized gantry of the present utility model hangs special-purpose banded high flexible cable, the many stranded formation twisted copper conductors 1 of thin copper wire, the stranded lay ratio of copper wire is (5～7): 1, twisted copper conductors 1 is coated with ethylene propylene rubber insulated layer 2 and constitutes insulated wire cores, each insulated wire cores is coated with cotton braid 3 outward respectively, the edge cores formation cables that are arranged side by side that thoroughly do away with more, space between each insulated wire cores is filled with the rope made of hemp 4 that is formed by strands, cable is extruded with Hypalon inner sheath 5 outward, Hypalon inner sheath 5 is coated with nylon fiber braid 6, its coverage rate is not less than 85%, the nylon fiber braid 6 outer Hypalon oversheaths 7 that are extruded with.
This cable has satisfied large-sized gantry and has hung the special small-bend radius that accessory cables is required, the frequent requirement of moving bending, hanging operation, overcome drawbacks such as the disconnected core of prior cable stressed and recurrent conductor in running, damage in insulation, insulation property weaken fast, aging acceleration, had weather-resistant, operation advantage easily.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
