Technical field
The present invention relates to field of cable technology more particularly to a kind of antitorque stubborn high life cables.
Background technology
With industry sizes such as China electric power industry, data communication industry, urban track traffic industry, car industry and shipbuildings
Constantly expand, the demand of electric wire will also be increased rapidly, following electric wire industry also has huge development potentiality.Pin at present
To different use environments, the structure of cable is varied, such as often will be with equipment in the equipment of some movements
The mobile cable pulled and hauled a man on the ground, this kind of cable will mainly consider wear-resisting property.But upper this kind of cable is still permitted at present
More shortcomings, it would be highly desirable to improve.
The content of the invention
Based on above-mentioned background technology, the present invention proposes a kind of antitorque stubborn high life cable, makes the electricity
Cable can not only have good abrasive resistance, but also torsion can will not be generated during dragging and is twisted.
The present invention proposes a kind of antitorque stubborn high life cable, including：Cable core, counterweight core, inner restrictive coating and external sheath layer,
Wherein：
Inner restrictive coating is coated on the periphery of cable core in the form of extruding；Counterweight core is located at the outside of inner restrictive coating and and cable core
It extends in the same direction, and the weight of counterweight core is more than the sum of weight of cable core and inner restrictive coating；External sheath layer is coated in the form of extruding
In the periphery of inner restrictive coating and counterweight core.
Preferably, on external sheath layer and positioned at side of the inner restrictive coating away from counterweight core one side be the first cambered surface, oversheath
It is the second cambered surface on layer and positioned at side of the counterweight core away from inner restrictive coating one side, and the second cambered surface radius is more than the first cambered surface half
Footpath.
Preferably, one side side of the counterweight core away from inner restrictive coating is arcwall face, and the arcwall face and the second cambered surface are coaxial
Arrangement.
Preferably, counterweight core includes several clump weights being equally spaced along cable core length direction.
Preferably, counterweight core close to the one side side of inner restrictive coating be equipped with along its length arrangement and to inner restrictive coating into
The arc groove of row cladding.
Preferably, wall thickness of the external sheath layer close to counterweight core one side is more than its wall thickness close to inner restrictive coating one side.
Preferably, on external sheath layer arbitrary cross section, the wall thickness of external sheath layer is by one of counterweight core away from inner restrictive coating
Successively decrease successively lateral one side of the inner restrictive coating away from counterweight core.
In the present invention, inner restrictive coating is extruded by the periphery in cable core, to enhance the protective capacities to cable core, passes through cable core
One side counterweight core is set, and make counterweight core weight be more than cable core and inner restrictive coating weight and, pulling the cable
Cheng Zhong, the one side where remaining counterweight core are contacted with ground, can not only prevent that cable core side from being worn, but also have
Good anti-tweak effect, so as to effectively improve the service life of cable.
Description of the drawings
Fig. 1 is a kind of cross-section diagram of antitorque stubborn high life cable proposed by the present invention.
Specific embodiment
In the following, technical scheme is described in detail by specific embodiment.
As shown in Figure 1, Fig. 1 is a kind of cross-section diagram of antitorque stubborn high life cable proposed by the present invention.
With reference to Fig. 1, the antitorque stubborn high life cable of one kind of proposition of the embodiment of the present invention, including：It is cable core 1, counterweight core 2, interior
Restrictive coating 3 and external sheath layer 4, wherein：
Inner restrictive coating 3 is coated on the periphery of cable core 1 in the form of extruding, to enhance the protective capacities to cable core 1；Counterweight core
2 are located at the outside of inner restrictive coating 3 and are extended in the same direction with cable core 1, and the weight of counterweight core 2 is more than the weight of cable core 1 and inner restrictive coating 3
The sum of amount；External sheath layer 4 is coated on the periphery of inner restrictive coating 3 and counterweight core 2 in the form of extruding, so that counterweight core 2 and cable core 1
It is formed whole.
The present invention so works：By extruding inner restrictive coating 3 in the periphery of cable core 1, to enhance the protection to cable core 1
Ability sets counterweight core 2 by the one side of cable core 1, and the weight of counterweight core 2 is made to be more than the weight of cable core 1 and inner restrictive coating 3
With make the cable during dragging, the one side where remaining counterweight core 2 is contacted with ground, can both prevent 1 institute of cable core
It is worn in one side, and with good anti-tweak effect, so as to effectively improve the service life of cable.
It is first on external sheath layer 4 and positioned at side of the inner restrictive coating away from 2 one side of counterweight core in addition, in the present embodiment
Cambered surface is the second cambered surface on external sheath layer 4 and positioned at side of the counterweight core 2 away from inner restrictive coating one side, and the second cambered surface radius
More than the first cambered surface radius, swung so that the cable can be in roly-poly shape in dragging process, it both can be to avoid external sheath layer 4
Wear surface concentrate, and its antitorque stubborn ability can be further enhanced.And in the present embodiment, counterweight core 2 away from inner restrictive coating 3 one
Side side is arcwall face, and the arcwall face and the second cambered surface are coaxially arranged, so that the cable during dragging, has good
Swing ability.
In the present embodiment, counterweight core 2 is equipped with close to the one side side of inner restrictive coating 3 and arranges and internally protect along its length
The arc groove that jacket layer 3 is coated, to reduce the height of C.G. of entire cable as far as possible.
In the present embodiment, counterweight core 2 includes several clump weights being equally spaced along 1 length direction of cable core, so that the electricity
Cable has good bending ability.
In the present embodiment, wall thickness of the external sheath layer 4 close to 2 one side of counterweight core is more than its wall close to 3 one side of inner restrictive coating
Thickness, and on 4 arbitrary cross section of external sheath layer, the wall thickness of external sheath layer 4 is inside by one side of the counterweight core 2 away from inner restrictive coating 3
One side of the restrictive coating 3 away from counterweight core 2 is successively decreased successively, makes the one side thickness that external sheath layer 4 contacts in working with ground larger, and
The segment thickness for being not involved in ground contact is told somebody what one's real intentions are, and so as to the thickness of reasonable distribution external sheath layer 3, improves its abrasive resistance.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
