Description
Technical field
This application involves but be not limited to field of track traffic, especially a kind of shoulder block formula Damping fastening.
Background technology
In recent years, it with the fast development with subway, inter-city passenger rail etc. for the Rail Transit System of representative, effectively alleviates
The nervous situation of urban transportation, and at the same time, vibration that these modes of transportation are brought, noise pollution are also given birth to the production of people
Work brings very big puzzlement.Rail fastening is playing the same of fixed rail function as the connecting component between rail and sleeper
When, vibration and noise reducing function is also increasingly valued by people.
At present, it has been proposed a series of rail fastening products with vibration and noise reducing in the market；And subtract numerous
It 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 solutions has been disclosed in 205134109 U.These disclosed prior arts are in systems by two layers of pad
Plate and two layers of elastomer match realization effectiveness in vibration suppression, and in fastener system, upper strata backing plate plays the role of carrying and fixed rail,
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.
The above-mentioned prior art can give full play to the vibration-damping function of two layers of elastomer, realize higher vibration damping amount, however also
It has the following disadvantages：
1st, relatively common fastener is with high costs.
In the structure of the 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 highest two components of cost in entire fastener system, accounts for more than the 70% of holistic cost, relative to common button
For the single-layer metal backing plate of part, one layer of metal caul is added additional, is significantly increased in cost.
2nd, anchor bolt is longer, easily occurs shear-deformable, and there are security risks.
It is only needed 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 railway roadbed simultaneously, entire 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 transmitted on anchor bolt, and since anchor bolt stretches out, railway roadbed foundation is relatively long, and cross force is produced
With regard to bigger, anchor bolt the shear-deformable of bigger can occur for raw shearing moment, substantially reduce the anchor bolt service life, make security row
There are hidden danger for vehicle.
3rd, compared to common fastener, prior art rail mounting height is higher.
Due in the prior art there are double layer of metal backing plate, compared to the single-layer metal backing plate of common fastener, the prior art
Fastener height it is higher, be usually higher by more than 14mm, the height for causing the rail flange of rail to sleeper surface is higher.The mounting height of rail
Height, on the one hand requiring the depth of section of subway tunnel increases, 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.
