Abstract
The invention discloses a damping track which comprises a track, a sleeper and a railway ballast, wherein a damping device is arranged between the sleeper and the railway ballast; the damping device comprises vibration damper plates and two dampers; the vibration damper plates are arranged in bearing positions on two sides of the sleeper; the two dampers are mounted inside the vibration damper plates and are symmetrically arranged on two sides of the sleeper; two cabins are formed in each shock absorber; the two cabins comprise a compression cabin and a damping chamber formed below the compression cabin; a columnar spring is arranged inside the compression cabin; one end of the columnar spring is connected with a compression guide rod; the other end of the columnar spring is connected with a compression plate; the compression plate is in sealed match with the walls of the dampers; the damping chamber is filled with air. By adopting the damping track, the damping property can be improved.
Description
Technical field
The present invention relates to technical field of transportation, specifically a kind of Shock-absorption track for railway.
Background technology
In track traffic, wheel and track, in high speed contact process, will unavoidably produce substantial amounts of impact energy, send huge noise, in order to reduce the noise in vehicle travel process, being everlasting at present track lower pad rubber ring, but railway load at home is big, 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
It is desirable to provide a kind of Shock-absorption track, improve better damping effect, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of Shock-absorption track, it is characterised in that: include track, sleeper, railway ballast, between sleeper and railway ballast, be provided with damping device；Described damping device includes vibration damper plate, amortisseur, and vibration damper plate is arranged on the load position of sleeper both sides；Described amortisseur is two, is arranged in vibration damper plate, is symmetricly set on sleeper both sides；Each amortisseur is provided with two cabins, including compression cabin, is arranged on the dampening chamber below compression cabin, and compression is provided with column spring in cabin, and column spring one end is connected to compression guide rod, and one end is connected to compression plate, and compression plate seals with damping wall and coordinates；Air it is full of in described dampening chamber.
Further, described sleeper is provided with the locating part of fixing amortisseur, locating part offers the hole adaptive with guide rod size.
The beneficial effects of the present invention is: adopt the present invention can be effectively improved damping effect, and reduce column spring pressure experienced by delivery air chamber, improving the service life of column spring, the cooperation of compression air and column spring can absorb wheel and track substantial amounts of impact energy of inevitable generation in high speed contact process to the full extent.
Accompanying drawing explanation
Fig. 1 is Shock-absorption track structural representation provided by the invention；
Fig. 2 is shock absorber structure schematic diagram provided by the invention.
Labelling in figure: 1 be vibration damper plate, 2 be sleeper, 3 be locating part, 4 be compression guide rod, 5 be track, 6 be compression cabin, 7 be column spring, 8 for dampening chamber.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment.
As shown in Figure 1 and Figure 2, a kind of Shock-absorption track, including track 5, sleeper 2, railway ballast, between sleeper 2 and railway ballast, it is provided with damping device；Described damping device includes vibration damper plate 1, amortisseur, and vibration damper plate 1 is arranged on the load position of sleeper 2 both sides；Described amortisseur is two, is arranged in vibration damper plate 1, is symmetricly set on sleeper 2 both sides；Each amortisseur is provided with two cabins, compresses cabin 6 and a dampening chamber 8 including one, and compression is provided with column spring 7 in cabin 6, and column spring 7 one end is connected to compression guide rod 4, and one end is connected to compression plate, and compression plate seals with damping wall and coordinates；It is full of air in described dampening chamber 8.Described sleeper 2 is provided with the locating part 3 of fixing amortisseur, locating part 3 offers the hole adaptive with compressing guide rod 4 size.
The present invention is in use, wheel and the track 5 substantial amounts of impact energy of inevitable generation in high speed contact process can be directly delivered on amortisseur, the compression guide rod 4 of amortisseur descends rapidly compression leg shape spring 7 to absorb energy, but owing to the compression performance of column spring 7 is limited, the impact energy absorbed is limited, this is, it is compressed to a degree of column spring 7 and gradually the energy of absorption can be passed to compression plate, the contracting of line space air pressure it is pressed under compression plate, absorb energy further, with the use of, can effectively protect 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 a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
