Abstract
The invention discloses a kind of insulating corrosion spring, including spring body, the spring body is in ω type structures, and the spring body is wrapped in insulating barrier, electrophoresis anticorrosive coat and epoxy resin layer successively from outside to inside.It the advantage is that：The present invention can reach insulation and corrosion-resistant effect simultaneously, elastic insulating strip is used to insulating joint position on interval circuit, coordinated insulation gauge apron is used, in the case where generation spring is contacted with clamping plate, because spring is insulator, track current is so as to can not possibly import rail；In the case where the insulating properties of spring are just in case be destroyed, when track current is transmitted by spring, when running into gauge apron, because gauge apron is also insulator, thus electric current is also impossible to importing rail, from without red band.Spring and gauge apron carry out insulating processing to preventing going out for red band to be now able to play a part of dual fail-safe respectively.
Description
Technical field
The present invention relates to hardware ＆ tools field, more particularly to a kind of insulating corrosion spring.
Background technology
With the continuous propulsion of railway speed increase, heavy duty work, trans-section seamless railway laying mileage is increasing year by year, interval
And the insulation set of track switch is insulating joint.Insulating joint can meet insulating requirements, and joint can be realized again
Seamless process requirement, is able to widely apply on gapless track because of its superperformance.Insulating joint structure is equal in design
The assembly space of contacting piece is considered, has reserved certain gap, is collided to prevent clamping part and clamping plate, the company's of causing electricity.Just
In the case of often, the fastener company's of not resulting in electrical phenomena after.But as road speed is improved constantly, load-carrying is continued to increase, to line
The impact on road is also progressively increased.Therefore, on rare occasion, loosening phenomenon occurs in fastener, causes spring to contact, lead with clamping plate
Cause joint even electricity.To avoid the generation of peril, a kind of elastic bar fastener that itself can be insulated is designed very necessary.And it is existing
Have that the anticorrosion effect of spring is undesirable, easily get rusty, short life：The working environment of elastic bar fastener is severe, exposes to the weather and drenches with rain, very
To also to be corroded by Urban Acid Rain acid mist or ocean salt fog, it is in for a long time in rugged environment, oxidation, corrosion can make spring
There is corrosion defect in surface, can largely reduce the fatigue life of elastic bar fastener, cause occur fatigue fracture, give train fortune
Defeated safety brings serious potential safety hazard.Spring after getting rusty need to be changed in time, not only add cost, also be wasted a large amount of
Manpower and materials.How it is permanently effective prevent spring corrosion, be always to trouble one of problem of railway department.
The content of the invention
It is anti-it is an object of the invention to provide a kind of insulation that simple in construction, easy to process, cost is relatively low, service life is longer
Rotten spring.
The technical solution adopted by the present invention is：
A kind of insulating corrosion spring, including spring body, the spring body are in ω type structures, and its innovative point is：The bullet
Bar body is wrapped in insulating barrier, electrophoresis anticorrosive coat and epoxy resin layer successively from outside to inside.
Further, the insulating barrier is polyvinyl chloride, and thickness is 0.1-1mm.
Further, the thickness of the electrophoresis anticorrosive coat is 2-4mm.
Further, the thickness of the epoxy resin layer is 0.1-2mm.
Beneficial effects of the present invention are as follows：
1. using elastic insulating strip to insulating joint position on interval circuit, coordinated insulation gauge apron is used, and is occurring spring
In the case of being contacted with clamping plate, because spring is insulator, track current is so as to can not possibly import rail；In the insulating properties of spring
In the case of can be just in case being destroyed, when track current is transmitted by spring, when running into gauge apron, due to gauge apron
It is also insulator, thus electric current is also impossible to importing rail, from without red band.Spring and gauge apron are carried out respectively
Insulating processing is to preventing going out for red band to be now able to play a part of dual fail-safe；
2. the double layer anticorrosive structure of electrophoresis anticorrosive coat and epoxy resin layer, its anti-corrosive properties are significantly improved, epoxy resin layer pair
Ferrious material has excellent adhesive force and anticorrosion, oil resistant, resistance to cathodic disbonding performance, and its effect compares alone electrophoresis anticorrosive coat
Or the design of epoxy resin layer, spring decay resistance of the invention significantly improved.
Brief description of the drawings
The present invention is described in further details with reference to the accompanying drawings and detailed description.
Fig. 1 is front view of the invention.
Fig. 2 is sectional view of the invention.
Embodiment
As shown in Figure 1 and Figure 2, a kind of insulating corrosion spring, including spring body 1, the spring body is in ω type structures,
Spring body is wrapped in insulating barrier 2, electrophoresis anticorrosive coat 3 and epoxy resin layer 4 successively from outside to inside.
The insulating resistance value of insulating barrier 2 reaches 500M Ω, thus electric current is also impossible to importing rail, from without red
Light belt, plays a part of dual fail-safe.
Electrophoresis anticorrosive coat 3 is wrapped in the whole outside of spring body 1, and epoxy resin layer 4 is sprayed on the whole of electrophoresis anticorrosive coat 3
Individual outside, can effectively obstruct source of corrosion, source of corrosion such as air, Exposure to Sunlight, drench with rain.Due to electrophoresis anticorrosive coat 3 and epoxy resin
Layer 4 is thicker, with preferable anti-wear performance, effectively slows down electrophoresis anticorrosive coat 3 and epoxy resin layer 4 uses process in anti-corrosion spring
In abrasion, extend spring service life.
Described above is the preferred embodiment of the present invention, it is impossible to the interest field of the present invention is limited with this.It should refer to
Go out, for those skilled in the art, technical scheme is modified or equivalent substitution, all
Protection scope of the present invention is not departed from.
