Description

Technical Field

[0001] The present invention relates to the technical field of maglev transportation systems, and more particularly, to a multi-functional perforated pipe beam for a maglev transportation system. Background Art

[0002] Maglev transportation systems have received extensive attention due to their high efficiency, low noise, and low pollution. Currently, maglev trains are mainly divided into two types: atmospheric pressure maglev and vacuum maglev. The maximum operating speed of atmospheric pressure maglev is about 600 km / h, and the maximum operating speed of vacuum maglev can reach 1000 km / h. The two have different requirements for infrastructure construction.

[0003] Currently, the research on atmospheric pressure maglev systems is relatively mature, and there are many commercial operation line implementation precedents worldwide. The research on vacuum maglev systems is still in its infancy, and only a few test lines have been implemented and constructed worldwide. Since the vacuum maglev system has greater advantages than the atmospheric pressure maglev system in terms of speed, energy efficiency, environmental protection, etc., in order to adapt to the development trend of maglev transportation technology and consider the current situation of maglev technology research, when constructing maglev lines at this stage, if the infrastructure can not only meet the operating requirements of the near-term atmospheric pressure maglev system but also reserve the conditions for upgrading to a vacuum maglev system in the long term, the difficulty of upgrading the future atmospheric pressure maglev system to a vacuum maglev system can be greatly reduced.

[0004] The existing bridge forms of maglev transportation systems do not comprehensively consider the requirements for upgrading the atmospheric pressure maglev system to a vacuum maglev system, resulting in difficulties in upgrading the atmospheric pressure maglev system to a vacuum maglev system. Therefore, how to meet the requirements for upgrading the atmospheric pressure maglev system to a vacuum maglev system is an urgent problem to be solved in this technical field.

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0033] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0034] As Figures 1-3 and Figure 6 shown, this embodiment provides a multi-functional perforated pipe beam for a maglev transportation system, which is characterized by including:

[0035] A U-shaped beam 1, which is used to be erected on a pier 6;

[0036] An n-shaped plate, which is fixedly connected to the U-shaped beam 1. A pipe through which a maglev train passes is formed between the n-shaped plate and the U-shaped beam 1. The n-shaped plate is also provided with a plurality of reserved holes 21 arranged in an array, and the reserved holes 21 are used to provide air circulation for an atmospheric pressure maglev system;

[0037] A plurality of sealing components, which are hermetically connected to the reserved holes 21. When the atmospheric pressure maglev system is upgraded to a vacuum maglev system, the sealing components are used to seal the reserved holes 21 so as to create a vacuum environment suitable for the operation of the vacuum maglev system.

[0038] It can be understood that the U-beam 1 is built on the bridge pier 6 to form a supporting roadbed for the passage of the maglev train, and the n-type plate is fixedly connected to the U-beam 1, and a pipeline for the passage of the maglev train is formed between the n-type plate and the U-beam 1. The multiple reserved holes 21 arranged in an array on the n-type plate provide air circulation for the normal pressure maglev system, effectively discharge the piston wind air from the outside of the pipe beam, reduce the influence of air resistance, and ensure the safety and efficiency of the train operation. In addition, in the normal pressure maglev system, the n-type plate with the reserved holes 21 can effectively reduce the creep of the U-beam 1, enhance the structural rigidity, and improve the line smoothness and ride comfort. When the normal pressure maglev system is upgraded to a vacuum maglev system, the reserved holes 21 are sealed by a closing component, so that the n-type plate and the U-beam 1 are a closed structure, so as to create a vacuum environment suitable for the operation of the vacuum maglev system. In this technical solution, a reserved hole 21 is opened on the n-type plate to provide air circulation for the normal-pressure maglev system, and the reserved hole 21 is sealed by a closing component to create a vacuum environment suitable for the operation of the vacuum maglev system. Through the preset convertible mechanism, the demand for upgrading the normal-pressure maglev system to a vacuum maglev system is met, avoiding the high investment and waste of resources caused by upgrading the normal-pressure maglev system to a vacuum maglev system, and achieving maximum economic benefits.

[0039] The U-shaped beam 1 comprises:

[0040] A concrete U-shaped beam 1, wherein the concrete U-shaped beam 1 is used to be built on a bridge pier 6;

[0041] A prestressed steel cage is embedded in the concrete U-shaped beam 1 and is used to support the concrete U-shaped beam 1 to meet the force requirement.

[0042] It is understandable that when casting the concrete U-shaped beam 1, a prestressed steel cage is embedded in the casting mold. By embedding the prestressed steel cage in the concrete U-shaped beam 1, the concrete U-shaped beam 1 is prestressed to meet the force requirements.

[0043] The n-type plate is configured as an n-type steel plate 2 , and the n-type steel plate 2 is fixedly connected to the U-shaped beam 1 .

[0044] It can be understood that by setting the n-type plate as the n-type steel plate 2, the aerodynamic force caused by the maglev train under normal pressure in the normal pressure maglev system and the influence of atmospheric pressure under vacuum after upgrading to a vacuum maglev system can be met, thereby ensuring the structural strength and applicability of the n-type plate.

[0045] like Figure 3 As shown, the closed component includes a closed steel plate 3 , which is arranged corresponding to the reserved hole 21 , and the closed steel plate 3 is sealed and connected to the n-type steel plate 2 .

[0046] It is understandable that after the closed steel plate 3 is hermetically connected to the n-shaped steel plate 2, the reserved hole 21 is blocked and sealed to facilitate the creation of a vacuum environment suitable for the operation of the vacuum maglev system. And after it is upgraded to a vacuum maglev system, the closed steel plate 3 bears the atmospheric pressure at the reserved hole 21.

[0047] The closed steel plate 3 abuts against the n-shaped steel plate 2, the edge of the closed steel plate 3 is welded to the n-shaped steel plate 2, and the edge of the reserved hole 21 is welded to the closed steel plate 3.

[0048] It is understandable that by welding the edge of the closed steel plate 3 to the n-shaped steel plate 2 and the edge of the reserved hole 21 to the closed steel plate 3, a double-layer hermetic weld is formed between the closed steel plate 3 and the n-shaped steel plate 2, ensuring the airtight effect of the closed steel plate 3 on the reserved hole 21, improving the load-bearing performance of the closed steel plate 3, and reducing the workload of later maintenance.

[0049] As Figure 4 shown, it further includes an annular reinforcing steel plate 4. The annular reinforcing steel plate 4 is connected inside the n-shaped steel plate 2. The annular reinforcing steel plate 4 is communicated with the reserved hole 21. The annular reinforcing steel plate 4 is used to strengthen the structural strength around the reserved hole 21.

[0050] It is understandable that after the annular reinforcing steel plate 4 is connected inside the n-shaped steel plate 2, the steel structure strength around the reserved hole 21 is strengthened by the annular reinforcing steel plate 4, avoiding fractures formed at the reserved hole 21.

[0051] As Figure 5 shown, the annular reinforcing steel plate 4 abuts against the inner wall of the n-shaped steel plate 2. The inner wall edge of the annular reinforcing steel plate 4 is welded to the n-shaped steel plate 2, and the outer wall edge of the annular reinforcing steel plate 4 is welded to the n-shaped steel plate 2.

[0052] It is understandable that by the annular reinforcing steel plate 4 abutting against the inner wall of the n-shaped steel plate 2, the annular reinforcing steel plate 4 is closely attached to the inner wall of the n-shaped steel plate 2. And by welding the inner wall edge of the annular reinforcing steel plate 4 to the n-shaped steel plate 2 and the outer wall edge of the annular reinforcing steel plate 4 to the n-shaped steel plate 2, the annular reinforcing steel plate 4 is connected to the n-shaped steel plate 2, ensuring the strengthening effect and connection stability of the annular reinforcing steel plate 4.

[0053] As Figure 1 and Figure 6 shown, a plurality of circumferential reinforcing ribs 5 are also arranged in an array on the outer wall of the n-shaped plate. The circumferential reinforcing ribs 5 are used to strengthen the structural strength of the n-shaped plate.

[0054] It can be understood that by arranging the circumferential reinforcing ribs 5 on the n-shaped plate in an array, the load-bearing performance and compressive strength of the n-shaped plate are enhanced, and the structural strength of the n-shaped plate is improved.

[0055] As Figure 1 and Figure 6 shown, the reserved hole 21 is arranged between two adjacent circumferential reinforcing ribs 5.

[0056] It can be understood that by arranging the reserved hole 21 between two adjacent circumferential reinforcing ribs 5, the steel structure around the reserved hole 21 is strengthened and protected by the two adjacent circumferential reinforcing ribs 5, avoiding breakage caused by concentrated stress at the reserved hole 21.

[0057] As Figure 1 and Figure 6 shown, the reserved hole 21 is arranged at the middle position of the side wall of the n-shaped plate.

[0058] It can be understood that by arranging the reserved hole 21 at the middle position of the side wall of the n-shaped plate, the structural strength of the n-shaped plate is guaranteed, and the n-shaped plate is prevented from breaking and cracking at the reserved hole 21.

[0059] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0060] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present invention, and all should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
