Embodiment 1

[0038] This embodiment provides a track, including a plurality of end-to-end sub-tracks, the interior of the sub-tracks is formed with a cavity for accommodating running gear, the sub-tracks include a bearing surface for carrying the running gear, and the bearing surface along the track An opening is provided in the extending direction. The track of this embodiment can be used in a suspended rail transit system. The rail vehicle can be connected to the running device arranged in the cavity through the suspension device, and the running wheels of the running device move along the bearing surfaces on both sides of the opening to drive the rail vehicle to move. .

[0039]In this embodiment, the bearing surface located on at least one side of the opening is provided with a connecting structure, the connecting structure includes a first matching portion arranged at the first end of the bearing surface and a second matching portion arranged at the second end of the bearing surface, ...

Embodiment 2

[0066] Figure 8 Shown in is a schematic structural diagram of the rail hoisting structure provided by an embodiment of the application; please refer to Figure 8 . This implementation provides a rail hoisting structure, including a support device 40 and the rail as described in the first embodiment above, wherein the rail can be any one of the rails in the first embodiment above, for the convenience of description, the first embodiment Track 10 is taken as an example for illustration.

[0067] On the track 10, the two ends of each sub-track 100 are provided with a first fixing device 150; the supporting device 40 includes a column 410 and a cantilever 420, and the column 410 is used to fix the cantilever 420 on the ground, and the axis of the cantilever 420 and the track The axes of 10 are perpendicular to each other, and the side of the cantilever 420 away from the column 410 is provided with a second fixing device 430, and the second fixing device 430 simultaneously conne...

Embodiment 3

[0070] This embodiment provides a suspended rail transit system, including a rail vehicle and the rail hoisting structure described in the second embodiment above.

[0071] Specifically, the rail vehicle can be connected to the running device arranged inside the track through the hanging device passing through the opening, and the running device can drive the rail vehicle to move along the track. The rail transit system also includes structures such as dispatching rooms and platforms scattered around the track.

[0072] Since the suspended rail transit system of this embodiment adopts the rail hoisting structure of the second embodiment above, it can reduce the probability of tremors when the traveling wheels travel in the rails, and improve the driving stability of rail vehicles.

Abstract

The embodiment of the invention provides a track, a track hoisting structure and a suspension type track traffic system. The track comprises a plurality of sub-tracks connected end to end, wherein a cavity used for containing a walking device is formed in each sub-track, each sub-track comprises a bearing surface used for bearing the walking device, and an opening is formed in each bearing surfacein the extending direction of the track; a connecting structure is arranged on a bearing surface on at least one side of the opening, the connecting structure comprises a first matching part arrangedat the first end of the bearing surface and a second matching part arranged at the second end of the bearing surface, and the shape of the first matching part and the shape of the second matching part are complementary; the sub-track is propped against the second matching part of another sub-track adjacent to the sub-track through the first matching part; and in a plane perpendicular to the extending direction of the track, the width of the first matching part is smaller than that of the bearing surface connected with the first matching part. The system is advantaged in that the chattering probability of the walking wheels can be reduced, and running stability of the track vehicle is improved.

Description

technical field [0001] The application relates to rail vehicle manufacturing technology, in particular to a rail, a rail hoisting structure and a suspended rail transit system. Background technique [0002] Rail transit system refers to a type of transportation system in which vehicles need to travel on specific tracks. Common rail transit systems include railway systems, subway systems, light rail systems, tram systems, and maglev rail systems. In the above different types of rail transit systems, the tracks are all set on the ground, and with the increasing traffic congestion on the ground, the suspended rail transit system has emerged as the times require. The suspended rail transit system suspends the rails and rail vehicles in the high-altitude space above the ground, thereby making full use of the space above the ground and helping to relieve the traffic pressure on the ground. [0003] In the solution of the related art, the track of the suspended transportation sys...
