Abstract
The utility model discloses a combined track which comprises a plurality of track plates, wherein, the connecting point between the track plates is trapezoidal, and the adjacent track plates are matched in a staggered manner and butted. Since the connecting point between the track plates is trapezoidal, the adjacent track plates are matched in a staggered manner and butted, the track joint is not a linear breaking joint, the trains run over when approaching the joint, thereby greatly reducing the noise.
Description
Technical field
The utility model belongs to the transportation technology field, relates in particular to a kind of combined orbit that reduces the rail train of noise.
Background technology
At present, the track port of rail train is square butt joint, because the temperature difference that weather brings makes track must reserve the shrinkage joint when laying, and train will form bigger vibrations and produce very big noise when driving to these joints, and this not only makes the passenger be fed up with, especially night, influence the passenger and have a rest, bring adverse effect also for the application life of train and end of rail, shortened the application life of rail.Along with the continuous speed-raising of train, the raising of train speed and the wheel-rail noise that causes is in rising trend, wheel-rail noise is the main sound source of train when the following speed of 250km/h is travelled.
The utility model content
The purpose of this utility model is to overcome the above-mentioned technical problem that existing track exists, and a kind of combined orbit is provided, and the utility model can reduce noise, improves the application life of track.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of combined orbit is characterized in that: described track comprises many track plates, and the junction of track plate and track plate is trapezoidal shape, and staggered cooperation of adjacent orbit plate docks.
The utility model also comprises buffer layer, and described buffer layer is arranged on the track plate of joint.
The employing the beneficial effects of the utility model are:
One, the junction of the utility model track plate and track plate is trapezoidal shape, and adjacent orbit is staggered to cooperate butt joint, and because of the interface of track is not the straight line breaking joint, train is to be fade-in to cross when driving to interface, has so just reduced the generation of noise greatly.
Two, the utility model also comprises buffer layer, and described buffer layer is arranged on the track plate of joint, the noise that has produced because of vibrations when further having reduced train driving.
Three, adopt the utility model can improve 3-5 years application life of track.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
A kind of combined orbit, described track comprise many track plates 1, and track plate 1 is trapezoidal shape with the junction of track plate, and staggered cooperation of adjacent orbit plate docks.The utility model also comprises buffer layer 2, and described buffer layer 2 is arranged on the track plate 1 of joint.Buffer layer 2 can be the flexiplast buffer layer.In the junction of track plate and track plate, port is that male and female cooperates butt joint with interface.
Above-described only is preferred implementation of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not the technical characterictic that the process creative work just can be associated; can also make some modification and improvement; these variations obviously all should be considered as equivalent feature, still belong within the protection domain of the utility model patent.
Claims (2)
1, a kind of combined orbit is characterized in that: described track comprises many track plates (1), and the junction of track plate and track plate is trapezoidal shape, and staggered cooperation of adjacent orbit plate docks.
2, combined orbit according to claim 1 is characterized in that: also comprise buffer layer (2), described buffer layer (2) is arranged on the track plate (1) of joint.
