Abstract
The utility model relates to a vibration-damping silencer, in particular to a rail vibration-damping silencer for rail traffic which is installed under the rail with the function of vibration damping and sound reducing, having a cylindrical barrel in which a partition plate is arranged. The barrel is partitioned into two parts of a vibration-damping barrel body and a sound-reducing barrel by the partition plate. The sound-reducing barrel is full of air. The vibration-damping barrel is provided with a base of spring, a head cover of spring, an inner spring and an outer spring. The inner spring and the outer spring are arranged between the base of spring and the head cover of spring. The inner ring and the outer ring of the inner spring are respectively provided with an inner retaining sleeve and an outer retaining sleeve of the inner spring. The outer spring is sheathed outside the inner spring, and the outer ring of the outer spring is provided with a casing filled with damping agent. The rail vibration-damping silencer for rail traffic of the utility model has compact structure, convenient handling, good vibration-damping and sound-reducing effect, long service life, safety and reliability without maintenance, and no pollution.
Description
Technical field
The utility model relates to damping flat device, especially a kind of track damping flat device that plays the track traffic of damping flat effect below the track that is installed in.
Background technology
In track traffic, will produce a certain amount of impact energy in wheel and the track contact process, thereby produce noise.In order to reduce the noise in the vehicle ' process, at present generally in the track lower pad with rubber or spring, but the rubber packing life-span is shorter, maintenance cost is bigger; And the damping of spring is less, thereby the effect of absorption of noise is relatively poor.
Summary of the invention
For the deficiency of the track damping flat device that overcomes existing track traffic, the utility model provides a kind of compact conformation, and is easy to loading and unloading, the damping flat is effective, and long service life is safe and reliable, need not maintenance, the feature of environmental protection is good, the track damping flat device of free of contamination track traffic.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of track damping flat device of track traffic, has cylindrical tube, be provided with dividing plate in the cylindrical shell, dividing plate is separated into damper cylinder body and flat cylindrical shell two parts with cylindrical shell, be full of air in the flat cylindrical shell, be provided with spring pedestal in the damper cylinder body, spring top cover, inner spring, outer spring, inner spring, outer spring is arranged between spring pedestal and spring top cover, the inner ring of inner spring and outer ring are respectively arranged with fixed cover and inner spring external fixation cover in the inner spring, outer spring is enclosed within outside the inner spring, the outer spring outer ring is provided with housing, is provided with damping agent in the housing.
Further: described inner spring and outer spring are cylindrically coiled spring.
Further: described damping agent is a polyisobutene.
The beneficial effects of the utility model are, the track damping flat device of track traffic of the present utility model, and compact conformation, easy to loading and unloading, the damping flat is effective, and long service life is safe and reliable, need not maintenance, and the feature of environmental protection is good, and is pollution-free.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the track damping flat device of track traffic of the present utility model.
Fig. 2 is the left view of Fig. 1.
1. cylindrical shells among the figure, 11. damper cylinder bodies, 12. flat cylindrical shells, 2. dividing plate, 3. spring pedestal 3,4. spring top cover, 5. inner spring, 6. outer spring, 7. fixed cover, 8. inner spring external fixation cover, 9. housing, 10. damping agent in the inner spring.
The specific embodiment
As Fig. 1, shown in 2, a kind of track damping flat device of track traffic, has cylindrical tube 1, be provided with dividing plate 2 in the cylindrical shell 1, dividing plate 2 is separated into damper cylinder body 11 and flat cylindrical shell 12 two parts with cylindrical shell, be full of air in the flat cylindrical shell 12, be provided with spring pedestal 3 in the damper cylinder body 11, spring top cover 4, inner spring 5, outer spring 6, inner spring 5, outer spring 6 is cylindrically coiled spring, inner spring 5, outer spring 6 is arranged on 4 of spring pedestal 3 and spring top covers, the inner ring of inner spring 5 and outer ring are respectively arranged with fixed cover 7 and inner spring external fixation cover 8 in the inner spring, outer spring 6 is enclosed within outside the inner spring 5, outer spring 6 outer rings are provided with housing 9, are provided with damping agent 10 in the housing 9, and damping agent 10 is a polyisobutene.
The impact energy that produces in vehicle and the track contact process partly can be because of the distortion of inner spring 5 and outer spring 6 and the absorption of damping agent 10, the vibrations in the vehicle ' process have been alleviated, the air that is full of in the flat cylindrical shell 12 plays the flat effect, thereby has reduced the noise in the vehicle ' process.
