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 technique
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, the vibration of these mode of transportation brings, noise pollution also give the production of people raw
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.
Currently, being proposed a series of rail fastening products with vibration and noise reducing function in the market；And subtract numerous
It shaking in fastener product, detachable double-layer vibration damping fastener realizes two layers of elastomer vibration damping to reaching higher effectiveness in vibration suppression,
And it realizes the dismounting and change of components with can be convenient, therefore is widely applied, the deep favor 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 layer 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 layer's backing plate, so that 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 disadvantage that
1, relatively common fastener is with high costs.
In the structure of the prior art, it is both needed to double layer of metal backing plate, 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 70% of overall cost or more, 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.
2, anchor bolt is longer, easily occurs shear-deformable, and there are security risks.
Anchor bolt relative to common single-layer pad board fastener is only needed through one layer of backing plate and one layer of elastomer, above-mentioned double
On the basis of anchor bolt in layer fastener then needs that upper iron plate, intermediate elastomeric, lower iron plate are pressed on railway roadbed simultaneously, entire anchor
Fixing bolt runs through upper iron plate, intermediate elastomeric, lower iron plate, directly contributes the increase of anchor bolt length.When 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 too long, and cross force produces
Raw shearing moment is just bigger, and anchor bolt can occur bigger shear-deformable, substantially reduces the anchor bolt service life, makes security row
There are hidden danger for vehicle.
3, common fastener is compared, prior art rail mounting height is higher.
Due to there is double layer of metal backing plate in the prior art, compared to the single-layer metal backing plate of common fastener, the prior art
Fastener height it is higher, be usually higher by 14mm or more, cause rail rail bottom higher to the height of sleeper surface.The mounting height of rail
On the one hand height requires the depth of section of subway tunnel to increase, 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, brings adverse effect to the safety and stability of whole system.
