Abstract
The utility model is a kind of road rail melting snow invariable power serial electric tracing band, including wire stylet, the wire stylet is wrapped with ptc layer, insulating barrier, screen layer and oversheath are sequentially provided with outside the ptc layer, stranded in the wire stylet to have an optical fiber cable, the oversheath is divided into the lower jacket of the latter half and the upper jacket of top half, and the section outline of the lower jacket is rectangular, the upper jacket is provided with outside arc convex, the oversheath and is coated with hydrophobic thin film.Oversheath of the present utility model includes the rectangular lower jacket of section outline and the upper jacket provided with arc convex, and lower jacket ensure that electric-heating belt and the closely knit laminating of rail, and contact area is bigger, also saves and sets up the cost payout that extra installed part is brought；Upper jacket can make electric-heating belt area of dissipation bigger, and snow melt effect is more preferable.Oversheath is externally provided with hydrophobic thin film, can so avoid corrosion of the snow-broth to electric-heating belt, makes the life-span of electric-heating belt longer.
Description
Technical field
The utility model is related to electric-heating belt and manufactures field, more particularly to a kind of road rail melting snow invariable power string
Join electric-heating belt.
Background technology
Cold-proof pass the winter of road rail is that have many track switches on an important process, road rail, and track switch is that train turns round
Place, track switch moves back and forth, and train just changes working line, and track switch moves into place, it is necessary to switch blade and track laminating, if it
Between there is accumulated snow accumulated ice just to move into place, train cannot just turn round.Processing such case generally requires manual cleaning accumulated snow
Or need special track switch to power up hot device clear accumulated snow, but so very labor intensive is while the power consumption of equipment is also suitable
Greatly, it cannot promote.
Many road rails bring the accumulated snow on fusing rail using electric tracing now, but traditional electric-heating belt is most
It is circular or flat, circular electric-heating belt directly can not be fitted on rail, it will usually an additional special peace
Piece installing is fixed, and so virtually adds cost, and the electric-heating belt of flat and circular electric-heating belt all have one such as
What makes the problem of area of dissipation is bigger, while how to prevent that corrosion of the snow-broth to electric-heating belt is also particularly significant.
The content of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of road rail melting snow invariable power series electrical
Heating tape.
The utility model to achieve the above object, using following technical scheme：
A kind of road rail melting snow invariable power serial electric tracing band, including wire stylet, the wire stylet are wrapped with PTC
Being sequentially provided with outside material layer, the ptc layer stranded in insulating barrier, screen layer and oversheath, the wire stylet has a light
Fine line, the oversheath is divided into the lower jacket of the latter half and the upper jacket of top half, the section outline of the lower jacket
Rectangular, the upper jacket is provided with outside the projection of arc, the oversheath and is coated with hydrophobic thin film.
The hydrophobic thin film uses SiO2/ PVDF composite superhydrophobic materials.
The wire stylet is tin plating round copper.
Thin layer of aluminum foil is provided between the insulating barrier and the screen layer.
The screen layer is almag screen layer.
The beneficial effects of the utility model are：Oversheath of the present utility model includes the rectangular lower jacket of section outline
With provided with arc convex upper jacket, lower jacket ensure that electric-heating belt and the closely knit laminating of rail, and contact area is bigger, also saves
Set up the cost payout that extra installed part is brought；Upper jacket can make electric-heating belt area of dissipation bigger, snow melt effect
More preferably.Oversheath is externally provided with hydrophobic thin film, can so avoid corrosion of the snow-broth to electric-heating belt, make the life-span of electric-heating belt more
It is long.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- wire stylets；2-PTC material layers；3- insulating barriers；4- screen layers；5- oversheaths；5.1- lower jackets；5.2-
Upper jacket；
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of road rail melting snow invariable power serial electric tracing band, including wire stylet 1, the wire stylet
1 is wrapped with ptc layer 2, and the ptc layer 2 is sequentially provided with insulating barrier 3, screen layer 4 and oversheath 5, the wire outside
It is stranded in core 1 to have an optical fiber cable, 5 points of lower jackets 5.1 and the upper jacket of top half for the latter half of oversheath
5.2, the section outline of the lower jacket 5.1 is rectangular, and the upper jacket 5.2 is provided with the projection of arc, the oversheath 5
It is coated with hydrophobic thin film outside.
The hydrophobic thin film uses SiO2/ PVDF composite superhydrophobic materials.
The wire stylet 1 is tin plating round copper.
Thin layer of aluminum foil is provided between the insulating barrier 3 and the screen layer 4.
The screen layer 4 is almag screen layer.
Oversheath 5 of the present utility model includes the rectangular lower jacket 5.1 of section outline and provided with shield on arc convex
Set 5.2, lower jacket 5.1 ensure that electric-heating belt and the closely knit laminating of rail, and contact area is bigger, also saves and sets up extra
The cost payout that installed part is brought；Upper jacket 5.2 can make electric-heating belt area of dissipation bigger, and snow melt effect is more preferable.Outer shield
Set 5 is externally provided with hydrophobic thin film, can so avoid corrosion of the snow-broth to electric-heating belt, make the life-span of electric-heating belt longer.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model implement not by
The limitation of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without
Improvement directly applies to other occasions, within protection domain of the present utility model.
