Technical field
The invention belongs to vibration damping track switch technical field, be specifically related to a kind of urban track traffic vibration damping track switch knot
Structure.
Background technology
Urban track traffic is higher to circuit operation safety, stability requirement, and circuit navigates within urban human
Mouth congested area, environment protectment protection is high.Continuous along with train running speed is accelerated with freight volume all the more
Intensive, the wheel track during operation mutually clashes into produced vibration and noise problem, affects track switch
Service life and surrounding enviroment, both increased regular maintenance cost, governs again the exploitation of property, unfavorable
In periphery economic development.
The common separated rail fastening of a large amount of employing in existing city rail traffic, generally installs rubber blanket under iron chair
Plate, provides elasticity for rail system, by turnout sleeper bolt, iron chair is fixed on sleeper top, once spiral shell
After bolt is tightened, rubber mat plate is by bigger compression so that it is lose partial elastic, the vibration damping of fastener
Performance is difficult to give full play to.
In recent years city rail traffic is in order to improve circuit damping property, and small part track switch have employed overall vulcanization type and subtracts
Shake fastener, can substantially meet line applications needs, but because of entirety sulfuration design, manufacturing cost is higher, and one
Denier sulfuric horizon is aging to come unglued, then the stability of fastener system, withdrawal resistance, effectiveness in vibration suppression will be substantially reduced,
Need integral replacing, increase maintenance cost, so vulcanization type Damping fastening does not obtains large area so far and pushes away
Wide application.

The present invention has the advantage that and effect:
1, the present invention uses double-deck nonlinear vibration reduction fastener system.One is to have prominent effectiveness in vibration suppression, with
Common track switch fastener is compared, and trouble district noise reduces 8dB.Two is that fastener system is stable；Show as fastener connection
Tying more reliable, upper iron chair, intermediate rubber pad, lower iron chair are assembled by this fastener by self-locking nylon jacket
Together, the stability of mechanical connection, bonding strength are above vulcanizing bonded fastener, thoroughly solve sulfur
Problem of coming unglued in the use of change type vibroshock；And fastener system withdrawal resistance strengthens, fastener system laterally and is turned round
Turn rigidity big, fastener system setting height(from bottom) about 20mm low compared with sulfuration type fastener, gauge holding capacity and safety
Property is higher, and fastener effectively controls rail wear.Three is to achieve trouble district rigidity homogenization；According to track switch
Structure and load position, by being optimized adjustment, not to middle rubber mat plate post structure and arrangement
The fastener rigidity that same trouble position design is different.
2, inventive joint uses rail vibration absorber joint plate.Rail vibration absorber joint plate is higher than ordinary couplings clamping plate,
Elevated section top end face is with 1:20 inclined-plane, consistent with wheel tread gradient, and train is by car during joint
Wheel tread can increase operation on top end face at vibration damping clamping plate, provides continuous print service condition for train, keeps away
Exempt from path to interrupt, reduce joint impact, thus reach to reduce the purpose of trouble district noise.
3, heel of switch rail uses elastic bendable type structure, it is ensured that tongue and guide rail stable connection, safety.
