Abstract
The utility model provides a kind of compound drum cable of low pressure, including power wire core conductor, wire core and control conductor group, the power wire core conductor outer cladding separation layer and insulating barrier form power wire core, tensile elements are that overcoat composition is extruded outside steel wire rope, the power wire core, wire core, control conductor group and tensile elements are twisted to form cable core, the tensile elements are in triangle arrangement in cable core, and enhancement layer and oversheath are coated with successively outside the cable core.By being externally provided with separation layer and insulating barrier in power wire core conductor, power wire core conductor is so set to possess excellent electric property and mechanical performance；Tensile elements are that overcoat composition is extruded outside steel wire rope, ensure that cable can bear continually to pull, the tensile elements are in triangle arrangement in cable core, ensure that the tensile elements of cable design for symmetrical three core, not only further increase the tensile property of cable, and the structural strength of cable is enhanced, it substantially prolongs the service life of cable.
Description
Technical field
Field of cable technology is the utility model is related to, specially a kind of compound drum cable of low pressure.
Background technology
Reel is the cable winder that electrical source of power, control power supply or control signal are provided for Large-scale Mobile equipment.It
The heavy-duty machinery for being widely used in the similar operating mode such as harbor portal crane, container crane, ship loader, derrick crane is set
It is standby.Due to using in particular circumstances, it is desirable to which cable has tension, wear-resisting, good bending property.With the hair of modern mining industry
Exhibition, the electric LHD (scraper of driven by power) as underground Trackless self charging appliance is because having without exhaust emission, making an uproar
The advantages that sound is small, work efficiency is high, operation is comfortable, good in economic efficiency, is widely used.At present, it is supporting with electric LHD
Reel towing cable, continually pulled during the cable use, cause cable body to be damaged, substantially reduce cable
Service life.
Utility model content
The utility model purpose is to provide a kind of compound drum cable of low pressure, can bear frequently to pull, greatly prolong electricity
The service life of cable.
To achieve these goals, the technical scheme used for：A kind of compound drum cable of low pressure, including power wire core are led
Body, wire core and control conductor group, the power wire core conductor outer cladding separation layer and insulating barrier form power wire core, tension member
Part is that overcoat composition is extruded outside steel wire rope, and the power wire core, wire core, control conductor group and tensile elements are twisted to form cable
Core, the tensile elements are in triangle arrangement in cable core, and enhancement layer and oversheath are coated with successively outside the cable core.
Compared with prior art, technique effect of the present utility model is：Power wire core conductor can be five class tinned copper wires
Compound to be twisted, insulating barrier can use EPDM glue material.By power wire core conductor be externally provided with separation layer and absolutely
Edge layer, power wire core conductor is so set to possess excellent electric property and mechanical performance；Tensile elements are anti-to be extruded outside steel wire rope
Sheath is formed, it is ensured that cable can bear continually to pull, and the tensile elements are in triangle arrangement in cable core, ensure cable
Tensile elements design for symmetrical three core, not only the further tensile property of increase cable, and the structure for enhancing cable is strong
Degree, substantially prolongs the service life of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Embodiment
The utility model is described in further detail with reference to Fig. 1.
A kind of compound drum cable of low pressure, including power wire core conductor 1, wire core and control conductor group, the power line
The outer cladding separation layer 2 of core conductor 1 and insulating barrier 3 form power wire core, and tensile elements are to extrude overcoat 9 outside steel wire rope 8 to form,
The power wire core, wire core, control conductor group and tensile elements are twisted to form cable core, and the tensile elements are in three in cable core
Angle is arranged, and enhancement layer 10 and oversheath 11 are coated with successively outside the cable core.
In above-mentioned technical proposal, power wire core conductor 1, which can be that five class tinned copper wires are compound, to be twisted, and insulating barrier 3 can
To use EPDM glue material.By being externally provided with separation layer 2 and insulating barrier 3 in power wire core conductor 1, so make power wire core
Conductor 1 possesses excellent electric property and mechanical performance；Tensile elements are to extrude overcoat 9 outside steel wire rope 8 to form, it is ensured that cable
It can bear continually to pull, the tensile elements are in triangle arrangement in cable core, and the tensile elements for ensureing cable are symmetrical
Three cores design, and not only the further tensile property of increase cable, and enhance the structural strength of cable, substantially prolongs cable
Service life.
The control conductor group includes the first control conductor group 6 and the second control conductor group 7 positioned at cable core center, control
The outsourcing insulating layer coating 3 of cable core conductor 5 forms control wire harness, and at least two control wire harness is mutually twisted to form the first control line
Core group 6, the second control conductor group 7, which is that four control wire harness are mutually twisted, to be formed.
Design two groups of control conductors, even if one group of control cable breaks down, also ensure that can plant equipment can locate
In in control range, guarantee plant equipment being capable of normal work.
As the concrete structure of wire core, the wire core is that the outsourcing insulating layer coating 3 of ground wire core conductor 4 is formed.
As the preferred scheme of overcoat 9, the overcoat 9 is the neoprene extruded outside steel wire rope 8.
As the preferred scheme of enhancement layer 10, the enhancement layer 10 is that polyester fiber braiding is formed.
As the preferred scheme of oversheath 11, the oversheath 11 is the neoprene extruded outside enhancement layer 10.
