Background technology
Recently as the fast development of urban rail transit in China, the vibration noise brought by its wheel-rail interaction is asked
Topic is increasingly serious, and the use of Damping fastening is an effective measures for alleviating this problem.
Rail fastening is exactly to the part for being coupled rail and sleeper (or other types sub-rail foundation) on track, in being also known as
Between union piece.Its effect is that rail is fixed on sleeper, keeps gauge and prevents rail relative to the vertically and horizontally shifting of sleeper
It is dynamic.Rail fastening includes railway spike, railway rail pad and elastic or rigid buckling piece etc..Fastener should be able to for a long time, effectively be kept
Rail is coupled with the reliable of sleeper, and its absorbing shock performance can be given full play under dynamic action, delays track residual deformation
Accumulation.Therefore it is required that it should have enough intensity, durability and certain elasticity, simple structure is also answered, is easily installed and tears open
Unload.In addition, for prestressed reinforced concrete tie, fastener should also have enough buckle press and gauge, horizontal adjusting value.It is existing
Damping fastening rail under to support be to use elastomeric material, elastomeric material easy aging under forced compression detrusion repeatedly makes
It is shorter with the life-span.
In summary, present inventor has found above-mentioned technology extremely during the present application technical scheme is realized
There is following technical problem less：
In the prior art, there is easy aging, the shorter technical problem of service life in existing steel rail vibration reduction fastener.
The content of the invention
The invention provides a kind of steel spring fastener of vibration and noise reducing, existing steel rail vibration reduction fastener is solved in the presence of easily old
Change, the shorter technical problem of service life realizes steel spring fastener rigidity and easily adjusted, the technique effect of service life length.
In order to solve the above technical problems, this application provides a kind of steel spring fastener of vibration and noise reducing, the steel spring button
Part includes：

In the steel spring rigidity on the outside of rail.
Wherein, check washer is provided between the fixing bolt and base.The damper be specially rubber cushion assembly or
Hydraulic damper.The base is provided with rail cant.The setting of rail cant be in order to allow rail stress along its axis direction.
Steel spring Damping fastening in the application, the rigidity of fastener and the regulation of damping are carried out using steel spring and damper
To meet the requirement of vibration and noise reducing.Steel spring is compared with the advantage of rubber：First, rigidity is easily adjusted, two, service life it is long, this hair
The vertical stiffness of bright achievable fastener is different in horizontal direction, makes on the inside of rail that rigidity is larger, and outside rigidity is smaller, so as to suppress
The upset of rail, slows down the generation of rail corrugation.
Steel spring Damping fastening, including spring, base, gauge apron, rubber pad placed under-neath rail, spring upper plate, steel spring, damping
Device, fixing bolt, check washer, height adjusting cushion plate, insulating pad.Spring uses e type springs, and spring is fixed on base boss simultaneously
Withhold gauge apron；Base is fixed by four bolts, and base or so respectively has the boss of a fixed spring, and base is provided with and bullet
The frictional contact surface that spring upper plate cooperates, boss of the base bottom provided with limitation steel spring position, base is provided with rail cant；
Spring upper plate is provided with the frictional contact surface cooperated with base, and spring upper plate top is used to limit glue under rail provided with rectangular recess
That pads vertically moves, boss of the spring upper plate bottom provided with limitation steel spring position；Steel spring be fixed on spring lower plate and
Between base and it is stuck in boss, steel spring position and number can be determined according to fastener design rigidity；Damper is installed
Between spring lower plate and base boss, dashpot type can select rubber cushion assembly or hydraulic damper as needed.
The rigidity of fastener of the present invention and damping can be adjusted by the installation site and number of steel spring and damper so that
Steel spring rigidity on the inside of rail is slightly above outside, so as to suppress the upset of rail, slows down the generation of rail corrugation.Car
The normal contact position of wheel and rail is on the inside of rail so that rail is inwardly overturn, the rigidity of increase inner side rail brace, can subtract
Small upset.The diameter of the steel spring material of inner side to outside is sequentially reduced, or the number of coils increases successively, you can realize inner side
Rigidity is higher than outside rigidity.Wherein, situations such as steel spring may be disposed to 3x3,3x4,4x4 under spring upper plate with distribution.
One or more technical schemes that the application is provided, have at least the following technical effects or advantages：
Steel spring fastener rigidity is easily adjusted, and service life is long, and the rigidity of fastener and damping can pass through steel spring and damper
Installation site and number adjust so that steel spring rigidity on the inside of rail is slightly above outside, so as to suppress rail
Upset, slow down the generation of rail corrugation.
