Abstract
The utility model discloses a track bumper shock absorber, including track, sleeper, railway ballast, be provided with damping device between sleeper and the railway ballast, damping device includes vibration damper plate, bumper shock absorber, and the vibration damper plate setting is in the load position of sleeper both sides, the bumper shock absorber is two, installs in the vibration damper plate, and the symmetry sets up in the sleeper both sides, every bumper shock absorber is equipped with compression guide arm, compression cabin, sets up in the damping room of compression cabin below, and the compression is provided with the spring holder in the cabin, is provided with eight column little springs on the spring holder, is provided with the clamping ring on the column little spring, and the clamping ring supports at compression guide arm lower extreme, the spring holder below is equipped with compression board, compression board and the sealed cooperation of shock attenuation wall, the indoor air that is full of of damping. Adopt the utility model discloses can improve damping performance.
Description
Technical field
The utility model relates to technical field of transportation, specifically a kind of track 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.
Utility model content
The utility model aims to provide a kind of track damper, improves better damping effect, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of track 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, compression cabin, is arranged on the dampening chamber compressed below cabin, and compression is provided with spring base in cabin, and spring base is provided with eight column little springs, column little spring is provided with pressure ring, pressure ring is against compression lower end of the guide rod; Be provided with compressive plate below described spring base, compressive plate and damping wall are sealed and matched; Air is full of in described dampening chamber.
Further, described sleeper is provided with the locating part of fixing damper, locating part offers the hole with guide rod size adaptation.
The beneficial effects of the utility model are: adopt the utility model effectively can improve damping effect, and reduce by delivery air chamber the pressure that column spring is subject to, improve the application life of spring, the cooperation of compressed air and spring can absorb wheel to the full extent and track unavoidably produces a large amount of impact energys in high speed contact process; Again because shock loading is not straight up and down certainly, there is certain left and right impact energy, adopt eight column little springs, can effectively share this impact energy equally, avoid the damage of spring.
Accompanying drawing explanation
Fig. 1 is the track shock absorber structure schematic diagram that the utility model provides.
Fig. 2 is the shock absorber structure schematic diagram that the utility model provides.
Mark in figure: 1 be vibration damper plate, 2 be sleeper, 3 be locating part, 4 for compression guide rod, 5 be track, 6 for compression cabin, 7 be column little spring, 8 be dampening chamber, 9 for spring base.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of track 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, compression cabin 6, is arranged on the dampening chamber 8 compressed below cabin 6, compression is provided with spring base 9 in cabin 6, spring base 9 is provided with eight column little springs 7, column little spring 7 is provided with pressure ring, pressure ring is against compression guide rod 4 lower end; Be provided with compressive plate below described spring base 9, compressive plate and damping wall are sealed and matched; Air is full of in described dampening chamber 8.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 to the utility model in high speed contact process, 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, and the compression guide rod 4 of damper presses down rapidly, by energy transferring to pressure ring, pressure ring compresses eight column little springs 7, and little spring distortion absorbs energy, owing to being provided with multiple little spring, little spring deformation extent is different, can lay down the shock loading of left and right.But because the compression performance of spring is limited; the impact energy absorbed is limited; this is; be compressed to column spring to a certain degree can gradually by the energy transferring that absorbs to compressive plate, compressive plate presses down and carries out air compressing, absorbs energy further; with the use of; can available protecting column spring, improve the application life of column spring, and improve damping efficiency.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. a track 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, compression cabin, is arranged on the dampening chamber compressed below cabin, and compression is provided with spring base in cabin, and spring base is provided with eight column little springs, column little spring is provided with pressure ring, pressure ring is against compression lower end of the guide rod; Be provided with compressive plate below described spring base, compressive plate and damping wall are sealed and matched; Air is full of in described dampening chamber.
