Description
Technical field
The invention belongs to urban track traffic Damping fastening technical fields, are related to steel rail vibration reduction fastener, and in particular to a kind of
Steel rail vibration reduction fastener for railcar phase library interior lines.
Background technique
When to having put into the metro depot that normal operation uses and carrying out upper cover Estate Development, building is covered due to ground
Iron operation and vibration exceeding the standard phenomenon occurs, at this moment a kind of effective control measures be fastener common in library is changed to have it is preferable
The Damping fastening of vibration isolation capability.
Not only speed is low for the train run in library, but also is unloaded, therefore library interior lines are generally used lesser 50Kg/
M rail, and do not make seamless processing, and also lightweight is small and exquisite for fastener used and sleeper, such as DJK5-1 type fastener or I type fastener, etc.
Deng.
Current existing Damping fastening almost contributes to main track.Not only speed is high for the train run on main track, and negative
Lotus is big, therefore main track is generally used biggish 60Kg/m rail, and makees seamless processing, and the geometry of fastener used and its sleeper
Shape is all larger and stocky, such as the pioneer's Damping fastening and German Cologne egg Damping fastening etc. of Britain.These are existing suitable
It is that can not directly replace existing common fastener, specific manifestation in vehicle phase library in the Damping fastening of main track are as follows: main track vibration damping button
The anchor bolt hole of sleeper mismatches in part and library, can not install；Main track Damping fastening floor space is generally than sleeper top surface in library
Greatly, it may appear that vacant state；Main track Damping fastening general thickness is big, and library interior lines can be allowed to be elevated, and rail top mark height is power supply etc.
The design basis height of system, its change can cause a series of adjustment, etc..In brief, existing main track vibration damping button
Part can not directly replace the common fastener in library interior lines, unless pouring again with carrying out matching after the track foundation of library interior lines is chiseled out
?.
For the rolling stock section to have put into effect, track foundation is chiseled out and is poured again can severe interference vehicle
The normal operation of section.It is desirable for this purpose that method be to make a kind of Damping fastening, bed-plate dimension be no more than existing sleeper, energy
It is installed using spiral channel nail hole existing in library, and fastener height need to guarantee that rail top mark height is constant.It is replaced using the fastener
The dismounting and installment work that fastener is only related to when original common fastener influence very little to the normal operation of rolling stock section.
Obtain this Damping fastening and there was only two methods at present, one is to existing Damping fastening, such as pioneer's fastener and
Cologne egg fastener etc. carries out size reduction design, and two be to carry out completely new Damping fastening special project design targeted specifically.For second
How kind method designs a kind of completely new Damping fastening in narrow space, had both met mounting condition limit value and fastener is high
Degree limitation, and can guarantee travel safety, while durable also there is good anti-vibration performance just to become upper cover Estate Development
In to existing line carry out fastener transformation a problem.
Summary of the invention

It is floating to set iron chair 2, i.e., is not contacted between floating iron chair 2 and pedestal iron chair 11；Wherein lateral displacement restraint layer 7 limits
The transverse movement of rail head processed.
Railway rail pad 9 is clamped between floating iron chair 2 and rail 5；
Spring 8, two limbs are pressed on rail 5 by Insulation rail distance keeper 28, and tail portion is placed on floating iron chair 2；It is double
Head screw spike 10, bottom is arranged in sleeper 4, and the bottom of the twin-feed spiral railway spike 10 is pierced by simultaneously upwards from sleeper 4
The plate lower bolster 3, pedestal 1, floating iron chair 2 are sequentially passed through, the top of twin-feed spiral railway spike 10 is successively arranged insulating bushing
17, plain washer 18, pre-compressed spring 19 and self-locking nut 20.Pre-compressed spring 19 by self-locking nut 20 by floating iron chair 2 and every
The pad 6 that shakes carries out precompressed, and is electrically insulated between twin-feed spiral railway spike 10 and floating iron chair 2 using insulating bushing 7.
With reference to Fig. 3, it is provided with reinforcing rib 15 on 11 annular plate of pedestal iron chair, pedestal iron chair 11 draws into middle word
13 back edge of type cavity is thin, improves its bending-twisting ability by reinforcing rib 15.And it is opened in 11 side opposite the angle of pedestal iron chair
Equipped with the mounting hole I 16 passed through for twin-feed spiral railway spike 10, have in I 16 position of mounting hole of anchoring screw and vehicle phase library short
Sleeve position is corresponding on sleeper, fastens pedestal iron chair 11 using mounting hole I 16 and by twin-feed spiral railway spike 10 in-orbit
On pillow 4.12 bottom of shoulder block is equipped with boss 14.Boss 14 is used to enhance the bending resistance of shoulder block 12, while limiting floating iron
Backing plate 2 along 5 direction of rail length travel.
With reference to Fig. 4, the floating iron chair 2 is with floating bottom plate 21 and its abnormal shape extended laterally out from floating bottom plate 21
Platform 22 intersects on the abnormal shape platform 22 and is equipped with spring tail portion mounting groove 25 and T-bolt mounting groove 24, and its special-shaped platform 22 is diagonal
Side is equipped with the mounting hole II 23 passed through for twin-feed spiral railway spike 10, and II 23 edge of mounting hole symmetrically offers insulating bushing

It sets and is abutted naturally between the lateral displacement constraint working face 26 of iron chair 2 by elasticity.When train passes through, floating iron chair 2
Lateral displacement constrains working face 26 with lateral displacement restraint layer 7 to be cooperated in the form of sliding friction therebetween.Lateral position
Both modes for moving restraint layer 7 can make the restraining force of floating 2 vertical motion of iron chair smaller, and to its transverse movement and turn over
The dynamic restraining force of transhipment is larger, advantageously ensures that and improves anti-vibration performance under travel safety.
When fastener is installed, the lower thread segment 102 and six of pedestal iron chair 11 and the utilization twin-feed spiral railway spike 10 of plate lower bolster 3
Angle block 103 is fixed on sleeper 4, and with insulating bushing 17, plain washer 18, pre-compressed spring 19 and self-locking nut 20 to floating iron
Backing plate 2 carries out precompressed.There is larger gap, i.e., floating iron chair 2 occurs micro- between twin-feed spiral railway spike 10 and insulating bushing 17
It is not directly contacted between twin-feed spiral railway spike 10 and 17 side wall of insulating bushing when small lateral displacement, prevents floating iron chair 2 from existing
Biggish cross shear is generated to twin-feed spiral railway spike 10 in vibration processes.
When rail 5 is installed, rail is fastened on by floating iron chair 2 by T-bolt 30, spring 8, plain washer 18 and nut
On, wherein T-bolt 30 is installed only on floating iron chair 2, is not attached to pedestal iron chair 11.
Damping fastening provided by the invention can realize high-grade anti-vibration performance in the case where guaranteeing travel safety, solve
To the vibration pollution problem of surrounding enviroment when train passes through.
Above-described embodiment, only presently preferred embodiments of the present invention, the practical range being not intended to limit the invention, thus it is all with
The equivalent variations that content described in the claims in the present invention is done should all be included within scope of the invention as claimed.
