Description
Technical field
The application relates to, but are not limited to field of track traffic, especially a kind of steel rail vibration reduction fastener backing plate.
Background technology
In recent years, with the fast development with subway, inter-city passenger rail etc. for the Rail Transit System of representative, effectively alleviate
The nervous situation of urban transportation；At the same time, these modes of transportation are brought vibration, noise pollution also give the production and living of people
Bring very big puzzlement.Rail fastening is as the connection member between rail and sleeper, while fixed rail function is played,
Its vibration and noise reducing function is also increasingly valued by people.
At present, in the market has been proposed a series of rail fastening products with vibration and noise reducing function；And subtract numerous
Shaking in fastener product, detachable double-layer vibration damping fastener realizes two layers of elastomer vibration damping so as to reach higher effectiveness in vibration suppression,
And the dismounting and change of parts can be conveniently realized, therefore is widely applied, it is deep to be favored by market.
In order to realize the dual layer elastomer vibration damping of rail fastening, prior art CN 2554216Y, CN 102979013A, CN
Different technical schemes has been disclosed in 205134109 U.These disclosed prior arts are in systems by two layers of pad
Plate and two layers of elastomer, which are engaged, realizes effectiveness in vibration suppression, and in fastener system, upper strata backing plate plays carrying and fixed rail effect,
Anchor bolt, which screws, to be screwed into the nylon sleeve being fixed in railway roadbed basis and is pressed on lower floor's backing plate, so as to which fastener system be consolidated
It is scheduled on the basis of railway roadbed, Fig. 1 is typical prior art construction figure.
Above-mentioned prior art can give full play to the vibration-damping function of two layers of elastomer, realize higher vibration damping amount, but also
Have the following disadvantages：
1st, relatively common fastener is with high costs.
In the structure of prior art, double layer of metal backing plate is both needed to, two layers of backing plate plays different effects respectively.This is two layers
Metal caul is two parts of cost highest in whole fastener system, accounts for more than the 70% of holistic cost, relative to common button
For the single-layer metal backing plate of part, layer of metal backing plate is adds additional, is significantly increased in cost.
2nd, anchor bolt is longer, and detrusion easily occurs, and potential safety hazard be present.
Only need to run through one layer of backing plate and one layer of elastomer relative to the anchor bolt of common single-layer pad board fastener, it is above-mentioned double
Anchor bolt in layer fastener is then needed on the basis of upper iron plate, intermediate elastomeric, lower iron plate are pressed on into railway roadbed simultaneously, whole anchor
Fixing bolt directly contributes the increase of anchor bolt length through upper iron plate, intermediate elastomeric, lower iron plate.During train operation, to rail
The cross force of application is delivered on anchor bolt, and because anchor bolt stretches out, railway roadbed foundation is relatively long, and its cross force is produced
Raw shearing moment is just bigger, and bigger detrusion can occur for anchor bolt, substantially reduce the anchor bolt life-span, make security row
Hidden danger be present in car.
3rd, it is higher compared to common fastener, prior art rail setting height(from bottom).
Due to double layer of metal backing plate in the prior art be present, compared to the single-layer metal backing plate of common fastener, prior art
Fastener height it is higher, be generally higher by more than 14mm, cause the height of the rail flange of rail to sleeper surface higher.The setting height(from bottom) of rail
Height, the depth of section increase of subway tunnel is on the one hand required, so as to increase the construction cost in tunnel；Another aspect rail arrives
The height of sleeper surface is higher, and the lateral stability of rail is poorer, and adverse effect is brought to the safety and stability of whole system,
