The track damping shock absorber is characterized by comprising a track, sleepers and railway ballasts, wherein a shock absorption device is arranged between each sleeper and the railway ballasts; the shock absorption device comprises shock absorption boards and shock absorbers; the shock absorption boards are arranged on force-bearing positions at the two sides of the sleepers; two shock absorbers are mounted in each shock absorption board and are symmetrically arranged at the two sides of each sleeper; each shock absorber is provided with a compression guide rod, a damping chamber and a compression chamber formed in the lower part of the damping chamber; the damping chamber is filled with air; a compression plate is arranged at the upper part of each damping chamber and is connected with each compression guide rod; an anti-leakage baffle is arranged between each damping chamber and each compression chamber; fluororubber seal rings are arranged on the surfaces, being in contact with the walls of the shock absorbers, of the anti-leakage baffles. 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 track traffic, wheel and track, in high speed contact process, will unavoidably produce a large amount of impact energys, send huge noise, in order to reduce the noise in vehicle travel process, track lower pad of being everlasting at present rubber ring, but railway load is at home large, and the actual life of rubber shock-absorbing circle is shorter, change trouble, in use for some time, its damping effect is more and more weak, and the noise sent increases.
Summary of the invention
The present invention aims to provide a kind of rail damping damper, improves better damping effect, to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of rail damping damper, is characterized in that: comprise track, sleeper, railway ballast, be provided with damping device between sleeper and railway ballast; Described damping device comprises vibration damper plate, damper, and vibration damper plate is arranged on the load position of sleeper both sides; Described damper 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, is arranged on compression cabin below dampening chamber, air is full of in described dampening chamber, compressive plate is provided with above dampening chamber, compressive plate is connected to compression guide rod, be provided with leakage-preventing baffle plate between dampening chamber and compression cabin, leakage-preventing baffle plate and shockproof wall contact surface are provided with viton seal ring; Compression is provided with a column spring in cabin, and column spring one end is welded on damper base, and one end is connected on leakage-preventing baffle plate, and column spring both sides are provided with aerating device, aerating device are provided with contact trigger switch.
Further, described sleeper is provided with the locating part of fixing damper, locating part offers the hole with guide rod size adaptation.
Beneficial effect of the present invention is: adopt the present invention effectively can improve damping effect, and reduce by delivery air chamber the pressure that column spring is subject to, improve the application life of column spring, the cooperation of compressed air and column spring can absorb wheel to the full extent and track unavoidably produces a large amount of impact energys in high speed contact process.

Mark in figure: 1 for vibration damper plate, 2 for sleeper, 3 for locating part, 4 for compression guide rod, 5 for track, 6 for compression cabin, 7 for column spring, 8 for dampening chamber, 9 for aerating device, 10 for contact trigger switch.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1 and Figure 2, a kind of rail damping damper, is characterized in that: comprise track 5, sleeper 2, railway ballast, be provided with damping device between sleeper 2 and railway ballast; Described damping device comprises vibration damper plate 1, damper, and vibration damper plate 1 is arranged on the load position of sleeper 2 both sides; Described damper is two, is arranged in vibration damper plate 1, is symmetricly set on sleeper 2 both sides; Each damper is provided with compression guide rod 4, dampening chamber 8, is arranged on compression cabin 6 below dampening chamber 8, air is full of in described dampening chamber 8, compressive plate is provided with above dampening chamber 8, compressive plate is connected to compression guide rod 4, be provided with leakage-preventing baffle plate between dampening chamber 8 and compression cabin 6, leakage-preventing baffle plate and shockproof wall contact surface are provided with viton seal ring; Compression is provided with a column spring 7 in cabin 6, and 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 provided with aerating device 9, aerating device 9 is provided with contact trigger switch 10.Described sleeper 2 is provided with the locating part 3 of fixing damper, locating part 3 offers the hole with guide rod size adaptation.
In use, wheel and track 5 unavoidably produce a large amount of impact energys in high speed contact process in the present invention, and shock loading is not straight up and down certainly, has certain left and right impact energy.Impact energy can be directly delivered on damper, the compression guide rod 4 of damper presses down rapidly, compression guide rod 4 presses down compressive plate, is compressed by air, then by energy transferring to column spring 7, camber of spring absorbs energy, if the shock loading be subject to is excessive, leakage-preventing plate presses down and touches contact trigger switch 10, triggers aerating device 9 and exits, improve the air specific pressure in compression cabin 6, prevent spring to be destroyed.First compressed air, rear Compress Spring, can available protecting column spring 7, improves the application life of column spring 7, and improves damping efficiency.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
