Description
Technical field
The invention belongs to field of urban rail, specifically propose a kind of resonant mode Damping fastening.
Background technique
In recent years, the development of the City Rail Transit Systems such as domestic subway, light rail is swift and violent, and the tight of urban transportation has been effectively relieved
Open situation.In a series of this construction, fastener system be it is essential, fastener is the connector of rail and sleeper, passes through spring
The mode for withholding rail realizes connection with rail, and the connection with sleeper is realized in such a way that anchor bolt is fixed.In city
In track transportation industry, Damping fastening is the maximum track vibration-reducing product of dosage at present.
The invention belongs to field of track traffic by CN201210533622.1, propose a kind of readily removable assembled separation type double-layer vibration damping button
Part system.A kind of readily removable assembled separation type double-layer vibration damping fastener system proposed includes elastic insulated pad, upper bottom under spring, rail
The elastic insulated pad of plate, bottom plate, lower plate and anchor bolt；Boss possessed by lower plate, the through-hole on upper plate；It is nested with
Bottom plate connector sleeve on boss forms the company in conjunction with convex-concave after boss rotation, with the boss on lower plate or with lower plate
It connects, axial limiting is carried out to bottom plate connector sleeve, and bottom plate connector sleeve is under mutual interlocking gear effect, it is mutual in radial direction with boss
Lock；The upper eaves portion position of bottom plate connector sleeve is withheld on upper plate top, is fastened on railway roadbed by interlocking cover board by anchor bolt.
CN201611042880.4 the present invention relates to a kind of double-layer vibration damping fastener of low clearance, the fastener include upper plate,
Elastic insulated pad under anchor bolt, spring and rail is additionally provided with elastic insulated under support base, compression insulation sleeve, holddown plate and plate
Pad；The lower plate of common fastener is reduced to bottom support base by the present invention, to greatly reduce the area and quality of lower plate, is dropped
The cost of low fastener.Simultaneously as fastener is not required to self-locking, disassembly is extremely convenient.In addition, after adopting the above technical scheme, fastener
Pressing force is adjustable, improves the adaptability of fastener, convenient for eliminating fastener processing and manufacturing and long-term operation bring error.
CN201220682492.3 the utility model belongs to field of track traffic, proposes that a kind of readily removable assembled separation type bilayer subtracts
