Rubber dust box for tracks {Rubber box used in low vibration track system}

The present invention relates to a rubber anti-vibration box for a track, more specifically, the embossed pins are formed integrally in the transverse direction on the protrusions formed along the inner surface in contact with the concrete sleepers to be received, and are generated during use. At least one hole is provided on the lower edge side of the inner bottom surface for outflowing the internal moisture to the outside to the rubber dust box for the track to maximize its durability and anti-vibration function.

In general, the railway, which is a infrastructure, has to cope with the demand for high speed and comfort along with the explosive transportation demand, and the maintenance of track maintenance personnel has become difficult due to the spread of the trend avoiding dangerous and hard work. Ease of use must also be secured.

Therefore, gravel roads that have been applied to railways have been replaced by concrete roads in terms of ease of maintenance and blocking of environmental pollution sources, especially in the case of subways, where maintenance is important as public transportation in the city. It is true.

Since these subways install rails on concrete roads, they are inadequate in dust protection compared to conventional gravel roads. This will adversely affect the surrounding structures and related facilities such as railroad cars and rails.

Referring to FIG. 1, a conventional track vibration isolator constructed in an iron bridge, a subway section, or the like having a concrete structure for the purpose of reducing such adverse effects is as follows.

The concrete sleeper (2) is stored in the dustproof box (boot) 1 on the concrete pattern, and an elastic pad for absorbing the impact load in the vertical direction between the bottom of the concrete sleeper (2) and the inner bottom of the dustproof box (1) ( pad) 3 is provided.

In addition, a rail pad 4 for absorbing vertical loads is provided between the upper surface of the concrete sleeper 2 and the bottom of the rail 8, and the concrete sleeper 2 is adjacent to both sides of the rail pad 4. Clip hook 5 is fixed to the upper surface, one side thereof is coupled to the clip hook (5) to press the upper surface of the transverse extension member (8a) of the lower rail (8) panda roll (10) 7) is provided, and the insulating block 6 is inserted between the pendroll 7 and the upper surface of the transverse extension member 8a of the rail 8.

This conventional track vibration isolator prevents a direct shock from being transmitted between the rail and the concrete phase by the load applied when the train passes over the rail 8 of the track to mitigate noise and vibration, and the fatigue applied to each structure. It serves to reduce.

The above-mentioned dustproof box 1 is a rubber material, but was originally a simple rectangular box, but a plurality of uneven portions 10 along the inner surface of the concrete sleeper 2 as shown in FIG. 2 to enhance the dustproof function. ) Was developed laterally.

Here, looking at the concave-convex portion 10, the groove portion (first groove portion, 10b-1) formed on the inner side of the opposing left and right end side surface is connected through the entire inner circumference of the dustproof box, the front and rear chapters facing each other (長On the inner side of the side surface, not only the first groove portion 10b-1, but also another groove portion (second groove portion, 10a-2) therebetween is further provided through the protrusion portion (second protrusion portion, 10a-2), Both ends of the second groove portion 10b-2 are formed from the long side to the rounded portion of the corner extending from the short side to the first groove portion 10b-1 on the short side. 1 The protrusion part 10a-1 is interposed, and the concave-convex part is formed in the long side side 2 times as close as the short side side.

This may be understood with reference to the front sectional view of FIG. 3A, the side sectional view of FIG. 3B, and the enlarged view of the upper and lower edges of FIG. 3C.

The vibration and noise of the side load generated when the train is driven by the above-mentioned uneven portion 10 are absorbed, that is, the uneven portion 10 of the side absorbs energy by the deformation of the load generated on the side and attenuates the vibration. In this case, the noise generated at the same time as the vibration is rotated along the groove portion 10b at the same time as the self deformation to absorb the generated noise energy to improve the dust-proof function.

However, since the uneven part 10 is protruded and can be easily worn, there is a need for a dustproof box that can be used for a long time because the service life is short and there is a disadvantage in maintenance.

On the other hand, when the conventional dustproof box is used in combination with the concrete sleeper (2), the generated moisture is introduced into the inside and is compressed between the elastic pad (3) and the bottom of the dustproof box, the vertical rigidity that the dustproof box should have And adversely affect the same power factor, worse the ride comfort of the occupant, impair the durability of the dust box, there is a problem that becomes another source of noise.

The present invention is devised to solve the above problems, by integrally forming a fin more embossed in the transverse direction on the protrusions of the plurality of irregularities formed along the inner surface in contact with the concrete sleeper, unevenness It is an object of the present invention to provide a rubber anti-vibration box for the track which prolongs the service life and increases the anti-vibration function by preventing direct wear of the parts.

In addition, by providing at least one hole in the bottom edge side of the bottom surface to flow out the internal moisture generated after being installed in combination with the concrete sleeper to the outside, orbital rubber dustproof to prevent adverse effects due to internal moisture Another purpose is to provide a box.

Other objects and advantages of the present invention will be described below and will be appreciated by practice of the present invention. In addition, the objects and advantages of the present invention can be realized by means and combinations shown in the appended utility model registration claims.
