Embodiment Construction

[0023] In order to further illustrate the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but they should not be construed as limiting the protection scope of the present invention.

[0024] Such as figure 1 As shown, the present invention is applied to a π-shaped track beam on a beam of a large-span high-speed maglev line, including a π-shaped track beam 1, an adjustable support 6 and a load-bearing box girder, the π-shaped track beam 1 and the The load-bearing box girders are connected through the adjustable support 6 to form a long-span track beam structure, and the load-bearing box girder adopts a single-line track or a double-line track or a multi-line track. Such as Figure 6-8 As shown, the π-shaped track beam 1 is mainly composed of two parts: the π-shaped beam main body 4 and the π-shaped beam support 5. The π-shaped beam main body 4 is a vertically extending three-dimensional π...

Abstract

The invention discloses a beam pi-type track beam applied to a large span high-speed maglev line. The beam pi-type track beam applied to the large span high-speed maglev line mainly comprises an upper layer pi-type track beam, a lower layer load bearing box girder and an adjustable support. A beam single-line track can be adopted, and a beam multi-line track can also be adopted. According to the beam pi-type track beam applied to the large span high-speed maglev line, enough rigidity can be provided, vibration can be effectively controlled, bridge deformation caused by a maglev vehicle running at a high speed is reduced, a large-span structure can be provided, and the demand of crossing over mountains, rivers and lakes is satisfied. The beam pi-type track beam applied to the large span high-speed maglev line has the advantages of reasonable structure, clear force transmission, novel design, material conservation, high mounting accuracy, small vibration deformation, large span and high navigation capacity.

Description

technical field [0001] The invention relates to the field of maglev transportation, in particular to a π-shaped track beam on a beam applied to a large-span high-speed maglev line. Background technique [0002] Maglev transportation is currently the fastest rail transportation mode in the world, with the advantages of high speed, energy saving, and low vibration and noise. On the basis of introducing and absorbing German technology, my country has built a number of maglev test lines through independent innovation. At present, there is no high-speed maglev transportation project in the world, and there is also a lack of track technology that matches the high-speed system. In order to further tap its speed advantage and develop high-speed maglev transportation, my country is currently exploring high-speed maglev transportation. Compared with the existing technology, its speed is greatly increased, and it puts forward new and more difficult requirements for vehicles and tracks...
