The second fixing device is connected to the joint of the two sub-tracks, that is, the third fixing plates 430 located at both sides of the cantilever 420 are respectively connected to the first fixing plate 310 at the first end of one sub-track and the first fixing plate 310 at the second end of the other sub-track adjacent thereto, and the fourth fixing plates 440 located at both sides of the cantilever 420 are respectively connected to the second fixing plate 320 at the first end of one sub-track and the second fixing plate 320 at the second end of the other sub-track adjacent thereto.

Example two

The embodiment provides a suspension type rail transit system, which comprises a rail vehicle and a rail hoisting structure as described in the first embodiment.

Specifically, the rail vehicle can be connected with the running gear arranged in the track through the hanging device penetrating through the opening, and the running gear can drive the rail vehicle to move along the track. The rail transit system also includes a dispatch room and stations dispersed throughout the rail.

The suspension type track traffic system of this embodiment is owing to adopted the track hoisting structure of above-mentioned embodiment one, consequently the track is difficult for taking place to twist during operation, and the security is better.

In the description of the present application, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be considered as limiting the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

While the preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all alterations and modifications as fall within the scope of the application.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations as well.
