Through the adoption of the track damping shock absorber, the shock absorption performance can be improved.
Description
Technical field
The present invention relates to technical field of transportation, specifically a kind of rail damping damper for railway.
Background technology
In in rail traffic, wheel and track, during high speed contact, will unavoidably produce substantial amounts of impact energy, send out
Go out huge noise, in order to reduce the noise in vehicle travel process, normal in rail lower pad rubber ring at present, but at home
Railway load big, the actual life of ubber shock-absorbing circle is shorter, changes trouble, in use for some time, it subtracts
Shake effect is more and more weaker, and the noise sending increases.
Content of the invention
The present invention is intended to provide a kind of rail damping damper, improve more preferable damping effect, to solve the above problems.
For achieving the above object, technical scheme is as follows:
A kind of rail damping damper it is characterised in that: include track, sleeper, railway ballast, be provided between sleeper and railway ballast
Damping device；Described damping device includes vibration damper plate, damper, and vibration damper plate is arranged on the load position of sleeper both sides；Described subtract
Shake device is two, is arranged in vibration damper plate, is symmetricly set on sleeper both sides；Each damper is provided with compression guide rod, dampening chamber, sets
Put the compression cabin below dampening chamber, described damping is indoor to be full of air, is provided with compression plate above dampening chamber, and compression plate is even
It is connected to compression guide rod, between dampening chamber and compression cabin, be provided with leakage-preventing baffle plate, leakage-preventing baffle plate and damping wall contact surface
It is provided with viton seal ring；Compression is provided with a column spring in cabin, and column spring one end is welded on damper base
On, one end is connected on leakage-preventing baffle plate, and column spring both sides are provided with aerating device, and aerating device is provided with contact triggering
Switch.
Further, described sleeper is provided with the locating part of fixing damper, locating part offers and guide rod size
The hole of adaptation.
The beneficial effects of the present invention is: damping effect can be effectively improved using the present invention, and subtracted by delivery air chamber
The pressure that few column spring is subject to, improves the service life of column spring, the cooperation energy maximum journey of compressed air and column spring
Wheel is absorbed on degree and unavoidably produces substantial amounts of impact energy during high speed contact with track.
Brief description
Fig. 1 is the rail damping shock absorber structure schematic diagram that the present invention provides.
Fig. 2 is the shock absorber structure schematic diagram that the present invention provides.
In figure mark: 1 be vibration damper plate, 2 be sleeper, 3 be locating part, 4 be compression guide rod, 5 be track, 6 be dampening chamber, 7
For column spring, 8 be compression cabin, 9 be aerating device, 10 be contact trigger switch.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of rail damping damper it is characterised in that: include track 5, sleeper 2, railway ballast, sleeper
It is provided with damping device between 2 and railway ballast；Described damping device includes vibration damper plate 1, damper, and vibration damper plate 1 is arranged on 2 liang of sleeper
The load position of side；Described damper is two, is arranged in vibration damper plate 1, is symmetricly set on sleeper 2 both sides；Each damper
It is provided with compression guide rod 4, dampening chamber 6, is arranged on the compression cabin 8 of dampening chamber 6 lower section, in described dampening chamber 6, be full of air, damping
It is provided with compression plate, compression plate is connected to compression guide rod 4, is provided with leakage-preventing between dampening chamber 6 and compression cabin 8 above room 6
Baffle plate, leakage-preventing baffle plate and damping wall contact surface are provided with viton seal ring；Compression is provided with a column bullet in cabin 8
Spring 7, column spring 7 one end is welded on damper base, and one end is connected on leakage-preventing baffle plate, and column spring 7 both sides are arranged
There is aerating device 9, aerating device 9 is provided with contact trigger switch 10.It is provided with the spacing of fixing damper on described sleeper 2
Part 3, locating part 3 is offered the hole being adapted to guide rod size.
When using, wheel and track 5 unavoidably produce substantial amounts of impact energy, punching during high speed contact to the present invention
Hitting load is not straight up and down certainly, has certain left and right impact energy.Impact energy can be directly delivered on damper, damper
Compression guide rod 4 push rapidly, compression guide rod 4 push compression plate, air is compressed, then transfers energy to column spring
7, camber of spring energy absorption, if the shock loading being subject to is excessive, leakage-preventing plate pushes and touches contact trigger switch 10, triggering
Aerating device 9 is exitted, and improves the air ratio pressure in compression cabin 8, prevents spring to be destroyed.First compressed air, rear compression spring,
Can effective protection column spring 7, improve the service life of column spring 7, and improve damping efficiency.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
