Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that and described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those skilled in the art are obtained without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Many details are explained in the following description in order to fully understand the utility model, but this is practical new
Type can also be implemented using other than the one described here other way, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case where novel intension, therefore the utility model is not limited by the specific embodiments disclosed below.
Such as Fig. 1 is embodied to as shown in figure 3, a kind of railway track all insulation fastener device, including is fixed on rail
The backing plate 4 of 100 bottoms, the Insulation rail distance keeper 2 for compressing 100 two sides base angle of rail and for compressing Insulation rail distance keeper 2
Spring 3 further includes rail insulation set 1, and the rail insulation set 1 includes insulator foot 11 and insulation bent plate 12.
Insulator foot 11, between backing plate 4 and rail 100,11 arranged on left and right sides of insulator foot, which has, to be wrapped
The upward flange at 100 two sides base angle of rail, 11 upper and lower faces of insulator foot are equipped with multiple grooves 13, and upper and lower groove
13 or so interlaced arrangements.
Insulate bent plate 12, two groups including being coated on 100 web of the rail portion two sides of rail, 12 bottom of every group of insulation bent plate with
The flange end of corresponding insulator foot 11 is connected, and insulation 12 top of bent plate has the arc-shaped cavity 14 of half opening, described
Arc-shaped cavity 14 includes top horizontal-extending first flange outward, and the end of first flange is connected with to be extended downwards vertically
Second flange, second flange end are connected with aduncate third flange, have between the third flange and waist
Gap.
Wherein, the structure of rail insulation set 1 mainly prevents the surface water to be splashed on rail 100, while 11 bottom of insulator foot
Multiple grooves that portion's upper and lower faces are equipped with, and upper and lower groove or so interlaced arrangement, improve the grasp of insulator foot 11.Pad
Plate 4 and Insulation rail distance keeper 2 are dielectrically separated between rail and the earth.
In use, the package of rail 100 is dielectrically separated from by rail insulation package set 1, prevent rail from conduction, Insulation rail distance keeper
2 are held in the two sides that rail insulation covers 1 bottom, and spring 3 compresses Insulation rail distance keeper 2, at the same backing plate 4 by rail and sleeper every
From being allowed to cannot be conductive between the earth, so that rail is reached completely insulated, so as to improve the service life of rail fastening, simultaneously
Improve rail fastening long term reliability and safety under bad working environments.
In order to prevent because being contaminated, humidity, infiltration, decreasing insulating caused by the factors such as leak, so curved insulating
12 surface of plate has damp-proof layer.12 any surface finish of bent plate that insulate simultaneously makees anti-(water, greasy dirt, dust, iron filings etc.) adsorption treatment.
In order to make 12 difficult deformation of bent plate that insulate, good airproof performance, so the hardness of insulation bent plate 12 is than insulator foot 11
Hardness is high.Simultaneously insulate bent plate 12 use nylon or rubber material, insulator foot 11 use rubber material, insulator foot 11 with
The material used in bent plate 12 that insulate is different formulations, and the insulation performance of material product reaches 108Ω makes rail insulation cover 1
It is completely insulated.
