[0032] like Figures 1 to 8 As shown, the present embodiment provides a track structure for magnetic levitation transportation, comprising a sleeper assembly fixed on a rail support platform 1 and guide rails 2 fixed on both sides of the upper surface of the sleeper assembly, the sleeper assembly comprising a support plate 3 and a top plate 4 provided on the upper portion of the support plate 3, the support plate 3 being in a U-shape with an opening upward, the bottom of the support plate 3 being fixed on the rail support platform 1, the top plate 4 being fixed on the U-shaped opening of the support plate 3, and the guide rails 2 being fixed on the top plate 4.

[0033] The track structure of the maglev transportation provided in this embodiment includes a sleeper assembly including a support plate 3 and a top plate 4. Figure 3 As shown, the sleeper assembly has a simple structure, the overall weight of the track is lighter, the support plate 3 and the top plate 4 are detachable, and the sleeper assembly can be detached for transportation, which greatly saves the space occupied by the sleeper assembly and improves transportation efficiency. The track is lighter for long-distance transportation, which can reduce transportation costs and reduce the difficulty of construction, installation and position adjustment. It is convenient to apply the track structure to scenes with lower requirements for speed and transportation volume, such as tourism, science popularization and entertainment. Figures 5 to 7 As shown, the rail support platform 1 is arranged on the track beam 13. When installing the track structure on the rail support platform 1, fastener assemblies and connecting assemblies are required. First, the support plate 3 of the sleeper assembly is installed and fixed on the rail support platform 1 through the fastener assembly, and then the F-shaped guide rail 2 is fixed to the sleeper assembly through the connecting assembly. The support plate 3 is U-shaped with the opening upward, and the top plate 4 is arranged on the U-shaped opening of the support plate 3. There is more space between the support plate 3 and the top plate 4, which is convenient for the installation of the fastener assembly and the connecting assembly, thereby making the installation of the track structure more convenient. In addition, the sleeper assembly adopts a combination of the support plate 3 and the top plate 4, which has a stronger shock absorption ability.

[0034] The support plate 3 can be roll-formed, and can resist deformation through its own rigidity and the friction between it and the top plate 4, and should have good mechanical and mechanical properties.

[0035] In order to improve the strength of the support plate 3, as Figure 1 and Figure 8 As shown, a connecting plate 5 is fixed to the bottom of the support plate 3 where it connects to the rail support platform 1. Two connecting plates 5 are symmetrically arranged along the width of the track at the bottom of the support plate 3. Preferably, the connecting plates 5 are welded to the bottom of the support plate 3. The connection between the bottom of the support plate 3 and the rail support platform 1 needs to withstand significant forces. Welding the connecting plates 5 at this location greatly improves the connection strength of the support plate 3, ensuring a safe and reliable structure. Furthermore, the welding position can be adjusted to accommodate different beam widths and lateral spacing between rail support platforms 1, making track and bridge engineering designs more flexible.

[0036] This embodiment further explains the installation of the sleeper assembly on the rail support platform 1. Figure 1 、 Figure 4 and Figure 8 As shown, a first bolt 6 is pre-embedded in the top of the rail support platform 1, and a first mounting hole 501 is provided on the connecting plate 5. The first bolt 6 is used to cooperate with the first mounting hole 501 and the first nut 7 to fix the connecting plate 5 to the rail support platform 1. Preferably, two mounting holes are provided on the connecting plate 5, and the two mounting holes are respectively located on both sides of the sleeper assembly. Two first bolts 6 are correspondingly pre-embedded in the rail support platform 1. The first bolts 6 pass through the first mounting holes 501 on the connecting plate 5 and cooperate with the first nut 7 to fix the connector to the rail support platform 1, thereby fixing the sleeper assembly to the rail support platform 1.

[0037] In order to facilitate the adjustment of the distance between the sleeper assemblies along the extension direction of the line, such as Figure 4 As shown, the first mounting hole 501 includes a first aperture and a second aperture. The first aperture is the aperture of the mounting hole parallel to the direction in which the track extends, and the second aperture is the aperture of the mounting hole perpendicular to the direction in which the track extends. The first aperture is larger than the second aperture. The first mounting hole 501 is preferably an oblong hole, arranged along the direction in which the track extends, i.e., the first aperture of the oblong hole is larger than the second aperture. The first mounting hole 501 enables the sleeper assembly to be adjusted longitudinally along the track. The distance between the sleeper assemblies can be adjusted along the direction in which the track extends, thereby achieving longitudinal position adjustment of the rail row.

[0038] This embodiment further optimizes the above technical solution. A guard plate 8 is pre-embedded in the rail support platform 1. The guard plate 8 has a through hole formed therein, and the first bolt 6 is positioned within the through hole. The guard plate 8 is preferably made of iron. The guard plate 8 is pre-embedded in the top surface of the rail support platform 1 to effectively prevent damage to the rail support platform 1 from track loads. Furthermore, the first bolt 6, pre-embedded in the rail support platform 1, passes through the through hole in the guard plate 8. The guard plate 8 strengthens the first bolt 6 embedded in the rail support platform 1, making it difficult to pull out of the rail support platform 1.

[0039] Preferably, Figure 1 and Figure 8 As shown, an elastic pad 9 is provided between the guard plate 8 and the connecting plate 5. A second mounting hole is defined in the elastic pad 9, which corresponds to the position of the first mounting hole 501. The elastic pad 9 between the guard plate 8 and the connecting plate 5 improves the elasticity of the connection between the connecting plate 5 and the guard plate 8, thereby reducing damage to the guard plate 8 caused by vehicle vibration.

[0040] This embodiment further optimizes the above technical solution by installing a height adjustment pad above the guard plate 8. Preferably, the height adjustment pad is installed between the elastic pad 9 and the connecting plate 5 to adjust the height of the rail track. Of course, the height adjustment pad can also be installed between the guard plate 8 and the elastic pad 9. The head end of the first bolt 6 is embedded in the concrete rail support 1. The screw of the first bolt 6 passes through the guard plate 8, elastic pad 9, height adjustment pad, and connecting plate 5 from bottom to top, and is tightened with the first nut 7 to lock the connecting plate 5 to the rail support 1.

[0041] like Figure 8 As shown, in order to improve the strength of the sleeper assembly, a rib 10 is provided between the top plate 4 and the support plate 3. Welding the vertical ribs 10 between the top plate 4 and the support plate 3 can further improve the rigidity and deformation resistance of the sleeper assembly.

[0042] This embodiment further illustrates the installation between the support plate 3, the top plate 4 and the guide rail 2. Figure 1 and Figure 2 As shown, mounting portions are provided at both ends of the support plate 3, and through holes are provided at positions opposite to the top plate 4. The guide rail 2 is provided with through holes, and the guide rail 2 is fixed to the support plate 3 and the top plate 4 via a connecting assembly. Horizontal mounting portions are provided at both ends of the U-shaped opening of the support plate 3, and through holes are provided at positions corresponding to the mounting portions and the top plate 4. The guide rail 2 is also provided with through holes. The connecting assembly preferably uses a second bolt 11 and a second nut 12. The second bolt 11 passes through the through holes on the guide rail 2, the top plate 4, and the mounting portions of the support plate 3 from top to bottom in sequence, and is tightened in conjunction with the second nut 12, thereby fixing the guide rail 2 to the sleeper assembly.

[0043] Preferably, the through hole on the guide rail 2 is a countersunk hole. The second bolt 11 of the connecting assembly is preferably a hexagon socket bolt, and the second nut 12 is preferably a high-strength nut. After the second bolt is installed in the countersunk hole of the guide rail 2, it does not protrude from the surface of the guide rail 2. Therefore, when the maglev vehicle lands on the guide rail 2 and travels, the guide rail 2 will not affect the vehicle's pulleys and skids.

[0044] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
