Description

The modern streetcar track structure of vibration isolation type

Technical field

The utility model relates to modern tram, particularly the modern streetcar track structure of a kind of vibration isolation type.

Background technology

Modern tram is a kind of a kind of advanced person's who takes the lead in growing up in France mode of transportation, rises the later stage nineties in 20th century, at present successively at multiple city success construction operation such as France, Germany, Spain, China.Modern tram has the features such as capacity is large, speed is high, flexible novelty, strong adaptability, and development at home and abroad at present rapidly.

At present, what domestic and international modern streetcar track structure mainly adopted is the track structure of flush type, concrete structural shape is more, is mainly divided into: have fastener track structure and without fastener track structure, be mainly made up of the packed layer between grooved rail, road bed board and two rails.Find by inquiry the flush type track structure overall structure more complicated that these are conventional, construction assembling procedure is more, construction period is relatively long, and the elasticity providing for track structure is less, vibration and noise reducing poor-performing, the shortcoming such as the insulating properties of stray electrical current are limited.

Utility model content

Technical problem to be solved in the utility model is to provide the modern streetcar track structure of a kind of vibration isolation type, effectively to improve vibration and noise reducing performance, and reduces the galvano-cautery of stray electrical current to substructure.

It is as follows that the utility model solves the technical scheme that its technical problem adopts:

The modern streetcar track structure of vibration isolation type of the present utility model, comprise from bottom to top concrete railway board and the concrete bottom seat board of making, left side rail and right side rail are fixedly mounted on the end face of concrete railway board, it is characterized in that: the cross section of described concrete railway board and concrete bottom seat board is U-shaped, between concrete railway board, concrete bottom seat board, elastomeric isolation layer is set; Be arranged at intervals with along circuit bearing of trend the horizontal connecting elements of steel that its two ends are fixedly connected with left side rail, right side rail respectively.

The beneficial effects of the utility model are, elastomeric isolation layer under road bed board can play good effect of vibration and noise reduction, can provide good elasticity for track structure again, and there is good secondary effectiveness in vibration suppression, the design of U-shaped slot type can, current limit in whole track structure, can effectively reduce the galvano-cautery of stray electrical current to substructure; Between two one steel rails, adopting the horizontal connecting elements of steel to connect makes track structure have the ability of the suitable gauge of better maintenance, and improve the globality of track structure, in addition because two one steel rails are connected the electromotive force of two one steel rails is equated by the horizontal connecting elements of steel, can effectively reduce the leakage of traction current; Make with the track structure on lawn that track is more natural, environmental protection, can adapt to park, scenic spot etc. to environmental protection and the higher region of aesthetic requirement.

Brief description of the drawings

This manual comprises following two width accompanying drawings:

Fig. 1 is the profile of the modern streetcar track structure of the utility model vibration isolation type embodiment 1;

Fig. 2 is the profile of the modern streetcar track structure of the utility model vibration isolation type embodiment 2;

The title of member shown in figure and corresponding mark: concrete railway board 10, left side rail 11, right side rail 12, the horizontal connecting elements 13 of steel, Concrete Filled layer 14, anti-layer 15, lawn 16, elastomeric isolation layer 20, concrete bottom seat board 30.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated.

See figures.1.and.2, the modern streetcar track structure of vibration isolation type of the present utility model, comprises from bottom to top concrete railway board 10 and the concrete bottom seat board 30 of making, and left side rail 11 and right side rail 12 are fixed on the end face of concrete railway board 10.The cross section of described concrete railway board 10 and concrete bottom seat board 30 is U-shaped, between concrete railway board 10, concrete bottom seat board 30, elastomeric isolation layer 20 is set.Elastomeric isolation layer 20 adopts elasticity better, and insulating properties are damping material preferably, can adopt full paving or banded structure.Elastomeric isolation layer 20 can play good effect of vibration and noise reduction, can provide good elasticity for track structure again, and have good secondary effectiveness in vibration suppression, the design of U-shaped slot type can, current limit in whole track structure, can effectively reduce the galvano-cautery of stray electrical current to substructure.

See figures.1.and.2, be arranged at intervals with along circuit bearing of trend the horizontal connecting elements 13 of steel that its two ends are fixedly connected with left side rail 11, right side rail 12 respectively.The setting of the horizontal connecting elements 13 of steel makes track structure have the ability of the suitable gauge of better maintenance, and has improved the globality of track structure, can make in addition the electromotive force of left side rail 11, right side rail 12 equate, can effectively reduce the leakage of traction current.

With reference to by the embodiment 1 shown in Fig. 1, making Concrete Filled layer 14 space between described left side rail 11 and right side rail 12 inner sides in, this structure is applicable to the modern streetcar track of shared right of way.With reference to the embodiment 2 shown in Fig. 2, the end face of described Concrete Filled layer 14 is laid anti-layer 15, on anti-layer 15, lays lawn 16, and this structure is applicable to independent right of way, and the modern streetcar track that environmental protection or civic landscape are had relatively high expectations.

Some principles of the above modern streetcar track structure of the utility model vibration isolation type that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
