[0029] In view of the problem that the current rubber-tyred tram guide rail has poor structural stability, an embodiment of the present invention provides a rubber-tyred tram guide rail, the guide rail comprising:

[0030] Friction rails that cooperate with the rubber wheels of the tram, the number of the friction rails being at least two and being parallel to each other;

[0031] A guide groove for guiding the running direction of the tram, the guide groove is located between two adjacent friction rails, the guide groove is formed by two adjacent friction rails separated by a preset distance, and the two inner walls of the guide groove are the side walls of the two adjacent friction rails;

[0032] A plurality of cross beams are located below the friction rail, wherein a single cross beam is perpendicular to the extension direction of the friction rail, and a plurality of cross beams are evenly distributed along the extension direction of the friction rail.

[0033] Here, the guide groove is generally matched with the bogie of the tram to guide the turning of the tram, and this structure is also not available in the prior art. As for how to avoid friction damage, it is not the content of the embodiment of the present invention. Here, the preset distance formed by the preset distance between the two adjacent friction rails will be comprehensively considered according to the width of the tram and the width of the guide rail in implementation, and will not be described in detail.

[0034] The rubber-tyred tram guide rail of the embodiment of the present invention can improve the problem of poor structural stability of the current rubber-tyred tram guide rail by arranging multiple crossbeams under the friction rail to change the existing design of the guide rail with a small width-to-span ratio.

[0035] In some other embodiments of the present invention, the guide rail further comprises a longitudinal beam, the longitudinal beam is perpendicular to the horizontal plane, the upper end of the longitudinal beam is fixed to the friction rail, and the lower end of the longitudinal beam is fixed in the cross beam. The longitudinal beam can make the friction rail more firmly fixed in the cross beam, which is a better implementation.

[0036] In some other embodiments of the present invention, the friction rail is composed of steel profiles, which is simple to implement and is a better implementation method.

[0037] In other embodiments of the present invention, the friction rail is made of steel and concrete, that is, reinforced concrete. When the tram rail is long enough, that is, in the mass construction of the product, the cost is relatively low, which is a better implementation method for large-scale construction.

[0038] The embodiment of the present invention also provides a rubber-tyred tram track, the track includes any one of the guide rails described above and a support device for further supporting the guide rail; the support device includes a hanger and a hanger support beam fixed to the road surface at both ends, the lower end of the hanger is connected to the cross beam, and the upper end of the hanger is connected to the hanger support beam. In this way, the hanger can further support the guide rail, making the guide rail more stable and strong, which is a better implementation method.

[0039] In some other embodiments of the present invention, each of the cross beams is connected to two suspension rods, and the two suspension rods are respectively fixed at two ends of the cross beam. In this way, the supporting force is more balanced, which is a better implementation method.

[0040] In other embodiments of the present invention, the boom support beam is arched, and both ends of the arch are fixed to the road surface. Here, the arched boom support beam is rigid, making the support more stable. The arched boom support beam can reduce the load of the tower (which can be a bridge pier in the embodiment of the present invention) and the requirements of the foundation of the tower, and is a better implementation method.

[0041] In some other embodiments of the present invention, the suspension rod support beam includes two parallel arch ribs and a cross brace connecting the two arch ribs, and the spacing between the two arch ribs is adapted to the length of the cross beam. The two arch ribs are adapted to the two suspension rods, so that the force is more uniform, which is a better implementation. The cross brace makes the structure of the two arch ribs more solid and stable, which is a better implementation.

[0042] The embodiment of the present invention also provides a rubber-tyred tram road, which includes an elevated bridge and any of the rubber-tyred tram tracks described above, wherein the elevated bridge is made of reinforced concrete; the cross beams of the rubber-tyred tram tracks are fixed to the bridge deck of the elevated bridge, and the arch ribs of the rubber-tyred tram tracks are fixed to the bridge piers of the elevated bridge. The elevated bridge made of reinforced concrete can overcome the problems of easy buckling and large deformation of the single track in the prior art, and has a stronger bearing capacity. It is also possible to build rubber-tyred tram tracks with larger spans, for example, rubber-tyred tram tracks with a span of more than 35 meters.

[0043] In other embodiments of the present invention, the arch ribs and the bridge piers are connected in a simple support or fixed connection. This is a better implementation method because of its simple structure and easy implementation. Simple support or fixed connection can be applied to different viaducts with different loads, different spans, etc.
