The present invention has the advantages such as reasonable in design, long service life and resistance to low temperature are good, adopt a thermal insulation layer and No. two thermal insulation layers that conductor is carried out isothermal holding, improve the resistance to low temperature of cable, it is thus possible to guarantee the normal operation such as instrument, equipment under cryogenic, to better meet the demand of industrial development.
Description
Technical field
The present invention relates to a kind of cable, specifically a kind of drag chain cable of resistance to low temperature.
Background technology
The occasion moved around is needed at unit, in order to prevent cable to tangle, abrasion, pull with at random, often cable is put into cable-pulling chain, cable is formed protection, and cable can also with dragging chain to realize moving around, this kind can be followed and be dragged that chain carries out moving around and the special cable of nonabradable high flexibility is just drag chain cable, it is mainly used in industrial electronic system, automatically line is generated, storage facilities, robot, fire-extinguishing system, lifting machine, the field such as numerically-controlled machine and metallurgical industry, due to the singularity that drag chain cable uses, therefore requirement for drag chain cable is also relatively high, such as the requirement to resistance to low temperature, the resistance to low temperature of existing drag chain cable is subzero 45 DEG C, and the development along with industry, resistance to low temperature for drag chain cable requires raising further again, existing drag chain cable cannot continue the demand of satisfied current industrial development, the cable that urgent a kind of resistance to low temperature is good.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of reasonable in design, long service life, resistance to low temperature good, the cable of the normal operation such as instrument, equipment can be guaranteed under cryogenic, i.e. a kind of drag chain cable of resistance to low temperature.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of drag chain cable of resistance to low temperature, comprise sheath, insulation layer and conductor, described insulation layer is wrapped in the outside surface of conductor, the axle center place of described sheath is provided with tension and leads core, and the middle part that described tension leads core is provided with circular through hole, arrange circular through hole can improve cable molding on the one hand after snappiness, compared with leading core with traditional solid tension, snappiness is better, and like this in the use procedure of reality, cable self can better adapt to the movement of unit; Described insulation layer is distributed in the outside that tension leads core symmetrically, the outside surface of described insulation layer is enclosed with a thermal insulation layer, adopt a thermal insulation layer that the insulation layer being wrapped in a thermal insulation layer and conductor can play the effect of insulation, can ensure that conductor continues work when low temperature like this, thus improve the resistance to low temperature of cable, meanwhile, a thermal insulation layer can effectively prevent insulation layer and conductor to be damaged, and insulation layer and conductor is played a protective role; The inwall of described sheath is provided with No. two thermal insulation layers; described No. two thermal insulation layers are wrapped in the outside of a thermal insulation layer; utilize No. two thermal insulation layers that conductor is carried out further isothermal holding; enhance the resistance to low temperature of cable; the object being in No. two thermal insulation layer inside also can be played a protective role by No. two thermal insulation layers, avoids cable destroyed in the use procedure of reality.
The inner homogeneous of No. two described thermal insulation layers be inlaid with heat keeper, described heat keeper ovalize structure, described heat keeper is made up of asbestos fibre material. The heat keeper adopting fibrous magnesium silicate to make is embedded in No. two thermal insulation layers, can effectively improve the heat-insulating property of No. two thermal insulation layers, contribute to improving the resistance to low temperature of cable.
The thickness of a described thermal insulation layer is not less than the thickness of insulation layer, can guarantee the heat-insulating property of a thermal insulation layer on the one hand, also contributes to improving the intensity of a thermal insulation layer on the other hand.
The invention has the beneficial effects as follows: the present invention has the advantages such as reasonable in design, long service life and resistance to low temperature are good, adopt a thermal insulation layer and No. two thermal insulation layers that conductor is carried out isothermal holding, improve the resistance to low temperature of cable, it is thus possible to guarantee the normal operation such as instrument, equipment under cryogenic, to better meet the demand of industrial development.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the internal structure schematic diagram of the present invention;
Fig. 2 is the structural representation that the tension of the present invention leads core.
Embodiment
In order to the present invention is realized technique means, creation characteristic, reach object and effect is easy to understand, below the present invention is set forth further.
As shown in Figure 1 to Figure 2, a kind of drag chain cable of resistance to low temperature, comprise sheath 1, insulation layer 5 and conductor 6, described insulation layer 5 is wrapped in the outside surface of conductor 6, the axle center place of described sheath 1 is provided with tension and leads core 7, the middle part that described tension leads core 7 is provided with circular through hole 701, arrange circular through hole 701 1 aspect can improve cable molding after snappiness, compared with leading core with traditional solid tension, snappiness is better, like this in the use procedure of reality, cable self can better adapt to the movement of unit; Described insulation layer 5 is distributed in the outside that tension leads core 7 symmetrically, the outside surface of described insulation layer 5 is enclosed with a thermal insulation layer 4, adopt a thermal insulation layer 4 that the insulation layer being wrapped in a thermal insulation layer 4 and conductor can play the effect of insulation, can ensure that conductor 6 continues work when low temperature like this, thus improve the resistance to low temperature of cable, meanwhile, a thermal insulation layer 4 can effectively prevent insulation layer 5 and conductor 6 to be damaged, and insulation layer 5 and conductor 6 is played a protective role; The inwall of described sheath 1 is provided with No. two thermal insulation layers 2; described No. two thermal insulation layers 2 are wrapped in the outside of a thermal insulation layer 4; utilize No. two thermal insulation layers 2 that conductor 6 is carried out further isothermal holding; enhance the resistance to low temperature of cable; the object being in No. two thermal insulation layer 2 inside also can be played a protective role by No. two thermal insulation layers 2, avoids cable destroyed in the use procedure of reality.
