Description
Technical field
The invention belongs to rubber shock absorbers, and in particular to the rail traffic vehicles floor such as a kind of bullet train, subway is whole
Body carries vibration-proof structure.
Background technology
Currently, the floating floor mounting structure of rail traffic vehicles mainly realizes car body floor and interior ground by damper
The installation of plate connects, and since floor in a vehicle rigidity is certain, to meet deflection requirement of the floor in fully loaded, overload operating mode, subtracts
The device that shakes must keep smaller clipping room away from installation number is more, and needs to measure in advance in a pre-installation, demarcates damper installation
Position, then installed, installation effectiveness is low, and working hour is long.
Invention content
In order to overcome the above problem existing for prior art, the object of the present invention is to provide a kind of bullet train,
The rail traffic vehicles such as subway floor integrated carrying vibration-proof structure, solves damper number in traditional floating floor mounting structure
Amount is more, installation effectiveness is low, the problem of working hour length.
The rail traffic vehicles floor integrated carrying vibration-proof structures such as bullet train provided by the invention, EMU, upper end
It is connect with floor by screw, the vehicle body bottom frame connection of lower end and vehicle, it includes reinforcing beam, damper, mounting base, the peace
Dress seat is fixedly installed on vehicle body bottom frame, and the damper bottom is installed in mounting base, and damper is with mounting base using buckle
Formula connects, and is fixedly connected with reinforcing beam by bolt at the top of the damper, the reinforcing beam is connect by screw with floor.
The damper includes top plate, bolt, rubber base, and the top plate is embedded in the top of rubber base, the stud weld
It being connected at roof center, and is embedded at the top of rubber base, the upper end of rubber base is fixedly connected by bolt with floor or reinforcing beam,
Groove is equipped at the center of lower end, the lower end of rubber base is installed on inside mounting base, is connect using buckle-type with mounting base.
The reinforcing beam, which includes the transverse beam of 5-30 roots, 3-9 roots longitudinal beam, 6-30 is a increases beam, the 5-30 roots transverse beam
It is uniformly arranged in order, with the 3-9 root longitudinal beam right angle settings being uniformly arranged in order, the 6-30 are increased beam and are fixedly mounted respectively
In the infall of 3-9 roots longitudinal beam and 5-30 root transverse beams, the beam that increases is connect by bolt with damper.The 5-30 roots
Transverse beam, 3-9 roots longitudinal beam, 6-30 increase beam be metal material side it is logical.
The rail traffic vehicles floor integrated carrying vibration-proof structures such as bullet train provided by the invention, subway are beneficial
Effect is that the rail traffic vehicles floor integrated carrying vibration-proof structure vibration and noise reducing such as the high speed is realized whole stress, improved
Ground panel stiffness；Module train, subwayization installation, are greatly saved working hour, improve installation effectiveness.

Specific implementation mode
With reference to the accompanying drawings, in conjunction with the embodiments, to the rail traffic vehicles land used such as bullet train provided by the invention, subway
Plate integrated carrying vibration-proof structure, is described in detail.
Embodiment
- Fig. 3 referring to Fig.1, the rail traffic vehicles such as the bullet train, subway of the present embodiment floor integrated carrying vibration damping knot
Structure, upper end are connect by screw with floor 1, and the vehicle body bottom frame 2 of lower end and EMU connects, it include reinforcing beam 3, damper 4,
Mounting base 5, the mounting base 5 are fixedly installed on vehicle body bottom frame 2, and 4 bottom of the damper is installed in mounting base 5, vibration damping
Device 4 is connect with mounting base 5 using buckle-type, and 4 top of the damper is fixedly connected by bolt 7 with reinforcing beam 3, the reinforcement
Beam 3 is connect by screw with floor 1.
The damper includes top plate 6, bolt 7, vulcanized rubber body 8, and the top of 6 vulcanized rubber body 8 of the top plate is described
Bolt 7 welds together with top plate 6 to be embedded at the center at 8 top of vulcanized rubber body, and the upper end of vulcanized rubber body 8 passes through bolt
7 are fixedly connected with floor 1 or reinforcing beam 3, groove are equipped at the center of lower end, the lower end of vulcanized rubber body 8 is installed on mounting base 5
Inside is connect with mounting base 5 using buckle-type.
The reinforcing beam increases beam 11 including 15 longitudinal beams 10,18 of transverse beam 9,6, and 15 transverse beams 9 are equal
Even to be arranged in order, with 6 10 vertical weldings of longitudinal beam being uniformly arranged in order, described 18 are increased beam 11 and are fixedly installed in respectively
The infall of 6 longitudinal beams 10 and 15 transverse beams 9, the beam 11 that increases are connect by bolt 7 with damper 4.
It is that aluminum alloy square is logical that the longitudinal beam 10,18 of 15 transverse beams 9,6, which increases beam 11,.
Damper 4 designs suitable rigidity, to control deflection of the floor integrated carrying vibration-proof structure under the operating mode that overloads；
When mounting dampers 4, the bolt string of damper 4, which is crossed, increases the reserved bolt hole of beam 44, and collocation stop nut is realized and reinforcing beam
