Description
The application is the patent CN201511006977.5 proposed on December 30th, 2015 divisional application.
Technical field
The invention belongs to technical field of rail traffic, a kind of system of the double-deck track switch Damping fastening system of separate type is specifically proposed
Make method.
Background technology
The current track switch Damping fastening of China mainly has three kinds of structural shapes, is vulcanization base+iron chair form, double respectively
Layer sulfuration type fastener, vibration damping track switch base systems.
Vulcanize base+iron chair formula fastener i.e. using the damping base of bonding by Vulcanization type as damper unit, using track switch
Fastener iron chair is used as rail connective element；Vulcanization base be by upper iron plate and lower iron chair by way of the vulcanization of rubber, make
Upper iron plate and lower iron chair bonding are an inseparable entirety, double-deck sulfuration type fastener structures and the mechanism of action and vulcanization bottom
Seat+iron chair formula fastener is similar；Vibration damping track switch base systems devise three layers of iron chair, entirely through mechanical bind mode,
The detachable for realizing iron chair and damper unit is designed.
Several fastener patterns subject matter during production implementation and onsite application has two aspects above：First, track switch
Region fastener pattern is more, and several fastener patterns of the above are required to out many sleeve forming moulds, costly；Second, several above
The metalwork of form uses casting and molding method, and the product flatness of casting backing plate is difficult to control, the casting of especially long backing plate
Make；The flatness of fastener can also be affected because of the injustice of cast member.
In patent (CN201120345928.5), propose that a kind of track traffic, with replaceable steel rail vibration reduction fastener, is somebody's turn to do
Fastener mainly includes rail, spring base I, upper strata spring and track gauge block I；One end of upper strata spring is withheld on rail, another
End is connected on the spring base I on upper iron plate；Upper strata cushion is set between the orbiting end plate of rail and upper iron plate；
The both sides of upper iron plate have the spring base II, lower floor's spring and track gauge block II for being used for withholding iron plate；One end of lower floor's spring
On spring base II, the other end is withheld at the two ends of upper iron plate.The utility model can easily dismantle upper strata cushion, under
The parts of damage are individually changed, repaired by layer cushion, upper iron plate, lower iron plate, reduce maintenance cost and work
Amount.But stability requirement of the engineer applied to track traffic rail fixed structure is very high.Wherein upper iron plate, lower iron plate are in formation plate
Shape and regular shape, are stacked together；The structure of installation is stacked to upper iron plate and this multiple plate objects of lower iron plate, using spring
Though being coupled the purpose that can reach and be fixed, due to being that linear contact lay is withheld between spring and iron plate, elastic bar fastener system is stable
Property is not good enough.On the other hand, when the structure is used for switch zones, because iron plate length increases at track switch, spring is now still used
It is coupled, linear contact lay, which is withheld, can not meet stability requirement.
In patent (CN201220682492.3), it is proposed that a kind of readily removable assembled separation type for common rail section is double
Layer Damping fastening；Propose a kind of readily removable assembled separation type double-layer vibration damping fastener system, include under spring, rail it is elastic insulated pad,
The elastic insulated pad of upper plate, bottom plate, lower shoe and anchor bolt；The boss that lower shoe has, through the through hole on upper plate；
The bottom plate adapter sleeve on boss is nested with after boss rotation, is combined with the boss on lower shoe or with lower shoe formation convex-concave
Connection, to bottom plate adapter sleeve carry out axial limiting, and bottom plate adapter sleeve mutual interlocking gear effect under, with boss in radial direction
Interlocking；The upper eaves portion position of bottom plate adapter sleeve is withheld on upper plate top, is fastened on by interlocking cover plate by anchor bolt on railway roadbed.
The fastener system take into full account above and below iron plate and its intermediate member be all in flat features of shape, bottom plate is connected during fixed connection
The upper eaves portion and the plane of upper plate of set are withheld, using the interlocking of the boss with lower shoe one and bottom plate adapter sleeve by upper bottom
Plate is fixed together, and effectively increases the stability of upper and lower bottom plate connection.But fastener of the present utility model is primarily directed to general
Logical track section, is not directed to special track section, such as track switch section.Institute is shorter with floor length at common rail, and at track switch
Floor length increases, and higher requirement is proposed to attachment fastener.
In patent (CN201420515221.8), a kind of vibration damping track switch base systems are proposed.A kind of vibration reduction road proposed
Base systems of branching off include lower shoe, middle spring felt pad, upper plate, track switch fastener base, roll adjustment connection positioning component etc..On
Bottom plate, track switch fastener base are connected as one by roll adjustment locating, and connecting components, the relative position of track switch fastener base and upper plate
Putting can be adjusted by roll adjustment locating, and connecting components.Lower shoe, middle spring felt pad and upper plate locking are connected as one.
The utility model proposes vibration damping track switch base systems have that processing and manufacturing is simple, cost is low, detachable, safeguard replacement cost
The advantages of low, in-site installation facilitates.Meanwhile, the system be directed to special track section --- track switch section, up and down iron plate and its
In the case that related accessory length increases, and improve the connective stability of structure, and solve by iron plate fixed connection up and down together
Determine part replacement problem.But which employs three layers of iron chair structure, increased using raw material quantity, particularly in railway
When laying mileage is long, cost increase, in practical engineering application, the high shortcoming of cost is particularly highlighted.In addition, track switch fastener length
Differ, spring seat species is various, causes casting mould expense very high.On the other hand, due to upper bottom in three layers of iron chair structure
Plate and track switch fastener base are to be detachably connected, and vehicle by or will be by or away from the part rail when, rail and
Pedestal is all in strength vibrating state, and strength vibrating state as described above repeats to occur under rail behaviour in service, and easily causing can
Connect and loosen between the upper plate and track switch fastener base of dismantling connection, and then reduce security reliability；In addition, installing at the scene
When, it is necessary to which the position of workman scene adjustment track switch fastener base, operating efficiency is very low.This be by its structure bring can not gram
The defect of clothes.Again, three layers of iron chair structure are a further disadvantage is that setting height(from bottom) is too high, and three layers of iron chair are in installation process
In, upper strata height adjusting cushion plate is also set up in the middle of upper plate and track switch fastener base, therefore, the height than two layers of iron chair is high,
Security performance is reduced therewith.
Above prior art is all studied Damping fastening system, by improving fastener system, steady to improve structure
It is qualitative.But for track switch section Damping fastening system, do not propose but it is simple in construction, facilitate in-site installation and maintenance work,
The good fastener system of connective stability.On the other hand, in the prior art the metalwork of Damping fastening system all employ it is traditional
Casting and molding method, the processing request of casting technique is high, complex procedures, and the product flatness of casting backing plate is difficult to control, especially
It is the casting of long backing plate needed for track switch section, the problem of iron plate deforms in casting just protrudes very much；Patent
(CN201420515221.8) roll adjustment connection positioning component adjustment track switch fastener position base is used in tackle deformation, this
Sample just connects positioning component and vibration damping track switch pedestal at the upper roll adjustment that adds of upper iron plate of patent (CN201220682492.3) again
For roll adjustment.It is to remove under the level of original technology processing technology that roll adjustment, which connects positioning component and vibration damping track switch pedestal,
, if vibration damping track switch pedestal is formed directly on iron chair, it is impossible to reach required precision.In addition, the flatness of fastener
It can be affected because of the injustice of cast member；When train is through turnout passing different zones, track switch resistance to overturning is poor, increases switch area rail
The maintenance work of road parts, makes troubles to live operation maintenance.To sum up, existing track switch Damping fastening system casting accuracy
The defect such as low, security performance is low, cost is high is the technical problem that this area wishes to solve for a long time.
