Problems solved by technology

The open box section cannot form a closed loop due to the shear flow, and the torsional rigidity is small. It will have a large displacement under the action of eccentric load, which seriously affects the driving comfort.
In order to meet the design requirements, only a small span can be used, which limits the scope of application of the suspended monorail

Embodiment 1

[0025]Such asFigure 1-Figure 4 , The embodiment of the present invention provides a rail beam 1 for suspended monorail transportation, comprising a beam top plate 11, an open beam bottom plate 12, and a plurality of beam webs 13 arranged in parallel and spaced apart. The plate surface of the beam web 13 Parallel to the longitudinal direction of the rail and connected to the beam top plate 11 and the beam bottom plate 12 at the upper and lower ends respectively, the beam webs 13 are distributed on both lateral sides of the running area of ​​the beam bottom plate 12 and at least one of the beam webs 13 The quantity is not less than 2 to form the side box area.

[0026]The above-mentioned opening structure of the beam bottom plate 12 is a conventional technology in the art, and the length direction of the opening groove is parallel to the longitudinal direction of the track, which facilitates the arrangement and operation of bogies, etc.; generally, the left and right sides of the opening...

Embodiment 2

[0035]Such asFigure 5 withFigure 6 , The embodiment of the present invention provides a suspended monorail transportation bridge, including a supporting structure, and also includes two sets of track beams 1 for suspended monorail transportation provided in the first embodiment, and the two sets of track beams 1 pass through the cross beams 2 Connected, the transverse beam 2 is supported on the supporting structure.

[0036]As mentioned above, the track beam 1 has only one side box area and is located on the side of the track beam 1 close to the cross beam 2. The structural strength and rigidity of the corresponding beam section can be achieved by adjusting the width of the side box area; The span and curvature of the track beam 1 and different parts of the track beam 1 can adopt a uniform facade profile. Correspondingly, it can be connected to the cross beam 2 through the above-mentioned side box area, and the force transmission is smooth and the force is reliable.

[0037]As mentioned a...

Abstract

The invention relates to a track beam for suspension type monorail traffic, which comprises a beam top plate, an open type beam bottom plate and a plurality of beam webs; the plate surfaces of the beam webs are parallel to the longitudinal direction of a track, and the upper ends and the lower ends are respectively connected with the beam top plate and the beam bottom plate; the beam webs are distributed on the two transverse sides of a beam bottom plate walking area, and the number of the beam webs on at least one side is not smaller than two so that a side box area can be formed. In addition, the invention further relates to a suspension type monorail traffic bridge which comprises a supporting structure and two sets of track beams, the two sets of track beams are connected through transverse tie beams, and the transverse tie beams are supported on the supporting structure. The side box type section is adopted, closed shear flow can be formed when the side box type section is stressed, the rigidity and structural strength of the track beam are remarkably improved, the driving comfort is greatly improved, and therefore the design span of the suspension type monorail can be increased, and the application range of suspension type monorail traffic is widened.

Description

Technical field[0001]The invention belongs to the technical field of rail transit, and specifically relates to a track beam used for suspended monorail transportation and a suspended monorail transportation bridge adopting the track beam.Background technique[0002]Different from the traditional track beam, the track beam of the suspended monorail system bridge is the key component to realize its spanning ability. In the suspended monorail, the running wheels and steering wheels of the marshalling train are located in the track beam, and the running wheels walk on the beam bottom plate. The steering of the train is realized by the contact between the steering wheels and the beam web. At the same time, the cables and pipes of the line are also All are placed in the track beam.[0003]In order to meet the demarcation requirements, the cross section of the track beam is a lower open box beam. The open box section cannot form a closed loop due to the shear flow, and the torsional rigidity i...
