Description
Technical field
The present invention relates to technical field of transportation, specifically a kind of band oleo-gear railroad 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 band oleo-gear railroad 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 band oleo-gear railroad 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 compression guide rod movable up and down, damping shock absorption room, and damping shock absorption room is arranged on amortisseur bottom, and damping shock absorption indoor are filled with damping fluid；Upper end, described damping shock absorption room is provided with leakage-preventing baffle plate；Described damping shock absorption indoor arrange spring base, and spring base is provided with eight column little springs, and column little spring is against on pressure ring, and pressure ring is connected on leakage-preventing baffle plate；It is provided with device for storing liquid in described spring base, device for storing liquid is provided with liquid outlet, spring base is provided with and connects contacting trigger switch；Described amortisseur outer wall is provided with a liquid supply device, liquid supply device and the device for storing liquid conducting in spring base, and liquid supply device is provided with pressurization implementation of port.
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 little spring pressure experienced by delivery air chamber, improving the service life of column little spring, the cooperation of compression air and column little spring can absorb wheel and track substantial amounts of impact energy of inevitable generation in high speed contact process to the full extent.

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 band oleo-gear railroad track, it is characterised in that: include track 5, sleeper 2, railway ballast, between sleeper 2 and railway ballast, be 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 compression guide rod 4 movable up and down, damping shock absorption room 8, and damping shock absorption room 8 is arranged on amortisseur bottom, is filled with damping fluid in damping shock absorption room 8；Upper end, described damping shock absorption room 8 is provided with leakage-preventing baffle plate；Arranging spring base 9 in described damping shock absorption room 8, spring base 9 is provided with eight column little springs 7, column little spring 7 is against on pressure ring, and pressure ring is connected on leakage-preventing baffle plate；It is provided with device for storing liquid in described spring base 9, device for storing liquid is provided with liquid outlet, spring base 9 is provided with and connects contacting trigger switch 10；Described amortisseur outer wall is provided with a liquid supply device 11, liquid supply device 11 and the device for storing liquid conducting in spring base 9, and liquid supply device 11 is provided with pressurization implementation of port.Described sleeper 2 is provided with the locating part 3 of fixing amortisseur, locating part 3 offers the hole adaptive with guide rod size.
Present invention wheel in use and track 5 are inevitable in high speed contact process produces substantial amounts of impact energy, and shock loading is not straight up and down certainly, has certain left and right impact energy.Impact energy can be directly delivered on amortisseur, the compression guide rod 4 of amortisseur rapidly under press, compression guide rod presses anti-leak plate 4 times, transfer energy to column little spring 7 again, little spring deformation absorbs energy, multiple little springs are different according to stress, and the little spring at diverse location deforms difference, uninstalls left and right load.And it is filled with damping fluid in damping shock absorption room 8, and mainly damping fluid, damping fluid can have column little spring 7 deformation generation sluggishness, improves the ability of spring energy-absorbing.When damping oil deficiency in damping shock absorption room 8; impact load is excessive; under leakage-preventing plate, crimping contacts contact and triggers switch 10; it is fuel-displaced that device for storing liquid in trigger spring seat 9 opens liquid storage hole; improve the fluid in compression cabin than pressure, it is prevented that spring is destroyed, it is possible to effectively protection column little spring 7; improve the service life of column little spring 7, and improve damping efficiency.And fluid infusion of the present invention is convenient, it is thus only necessary to carry out liquid supply device 11 supplementing damping fluid, need not dismantle.
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.
