Description

Technical Field

[0001] This utility model belongs to the field of new transportation technology, and relates to a vacuum double-layer maglev-rolling train track system, and more particularly to a vacuum double-layer maglev-rolling train track system for high-speed transportation. Background Technology

[0002] Currently, global high-speed transportation relies entirely on air transport, but its operational system is complex, highly dependent, and subject to numerous constraints. In terms of equipment manufacturing, route scheduling, fuel consumption, and maintenance costs, the aviation system generally faces high costs and high operational barriers. Furthermore, it still relies heavily on external sources for key core technologies and supply chain control. These factors collectively limit the possibility of replicating, popularizing, and iterating aviation on a larger scale.

[0003] Therefore, land-based high-speed transportation is gradually being seen as a viable new direction. Current research focuses on two core technologies: one is vacuum pipeline systems, which significantly increase transportation speed by constructing low-air-resistance channels; the other is magnetic levitation technology, which significantly reduces mechanical friction through non-contact support, thereby improving operational efficiency and system lifespan. However, in practice, the former faces high costs and complexity in pipeline construction, sealing, and maintenance; the latter places high demands on track structure, power supply system, and levitation stability, and is difficult to control in terms of cost. Currently, there is no mature solution that can simultaneously achieve system efficiency, engineering feasibility, and large-scale deployment capability.

[0004] Therefore, it is necessary to propose a new type of high-speed train track system that, while ensuring high-speed operation and safety and reliability, achieves lower engineering complexity, higher operating efficiency and stronger environmental adaptability, so as to meet the future demand for efficient, autonomous and safe transportation in a wide-area transportation system. Utility Model Content

[0005] In view of this, in order to solve the problems of high engineering complexity, low operating efficiency and poor environmental adaptability of existing vacuum pipeline transportation and magnetic levitation combined technologies, which prevent large-scale deployment, this utility model provides a vacuum double-layer magnetic levitation-rolling train track system. By combining the vacuum environment and magnetic levitation and rolling composite bearing technology, it breaks through the bottleneck of traditional technology and realizes a more efficient and stable high-speed transportation system.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vacuum double-layer maglev-rolling train track system includes a pipe fixed to the foundation, two main load-bearing walls perpendicularly arranged inside the pipe along its length, and a partition wall inserted transversely between the two main load-bearing walls. The partition wall divides the area between the two main load-bearing walls into an upper passage and a lower passage, corresponding to the reciprocating directions of the train carriages, respectively. Track groups consisting of upper and lower rails are installed on the left and right sides of the upper and lower passages along their length. High-strength magnets are uniformly embedded on the lower surface of the upper rail to provide magnetic support for the train carriages, and rolling elements are uniformly arranged on the upper surface of the lower rail for guidance and auxiliary support during train operation.

[0008] Furthermore, both the upper and lower channels are vacuum channels, and the inner wall surfaces of these vacuum channels are coated with a polymer sealing film to maintain a vacuum environment that isolates the inside of the channel from the outside. Apart from the vacuum areas where the upper and lower channels are located, the rest of the inside of the pipeline is an air pressure area, which is used for the maintenance and repair of the pipeline and track assembly.

[0009] Furthermore, the train carriages maintain a non-contact or semi-contact support state with the track assembly consisting of the upper and lower tracks during operation, in order to reduce frictional resistance and improve operating efficiency and system life.

[0010] Furthermore, the spacing between the upper and lower tracks facilitates the embedding of the wing structures on both sides of the train, enabling stable guidance and buoyancy distribution for the train.

[0011] Furthermore, slots are provided on the opposite side of the main load-bearing wall, and the upper and lower rails of the corresponding track group are inserted into the corresponding slots.

[0012] Furthermore, the rolling elements are ball or roller structures.

[0013] Furthermore, both the pipeline and the track assembly adopt a modular segmented assembly structure, with an elastic sealing structure between each module to ensure the continuity and sealing of the vacuum area, and to facilitate the expansion, replacement or maintenance of the track system.

[0014] Furthermore, slots are provided on the inner wall of the pipe, and the corresponding main load-bearing wall is inserted into the corresponding slot for pre-fixation.

[0015] Furthermore, the inner wall of the pipe is fixedly connected to the side of the two main load-bearing walls that are far apart from each other by an auxiliary wall, thereby improving the supporting strength of the main load-bearing walls.

[0016] Furthermore, the pipeline is an integral cylindrical structure, installed on the surface or underground, with an outer ring of reinforced concrete forming the outer perimeter of the pipeline to provide overall structural support.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The vacuum double-layer maglev-rolling train track system disclosed in this utility model features a double main wall structure and a vertical track installation design, which improves the pipeline's load-bearing efficiency and space utilization. Specifically, it adopts a structure with main load-bearing walls on both sides of the pipeline, with the track assembly installed vertically inside the main load-bearing walls, which is completely different from the traditional horizontally arranged track system structure. The main load-bearing walls not only serve as the installation foundation for the tracks, bearing the train's running load, but also effectively support the pressure at the top of the tunnel and evenly transfer it to the foundation, thus significantly reducing the structural burden on the outer ring of the pipeline. A partition wall is set in the middle of the pipeline, dividing the internal space into upper and lower vacuum channels. This not only achieves spatial separation for the train's back-and-forth operation but also forms an isolation barrier between the vacuum and atmospheric pressure areas, enhancing structural stability. Through the coordinated design of the main load-bearing walls and the partition wall, the pipeline structure has higher strength, clearer functions, and significantly improved overall space utilization efficiency.

[0019] 2. The vacuum double-layer maglev-rolling train track system disclosed in this utility model features a composite track structure of maglev and rolling on opposite sides of the upper and lower tracks, which significantly reduces friction and energy consumption between the train and the track assembly during operation. Specifically, the track system inside the main load-bearing wall combines maglev and rolling load-bearing methods. Magnets are embedded in the upper track to achieve non-contact levitation of 90% of the train's weight, while the lower track has ball bearings or roller bearings for guidance and auxiliary support. This composite structure differs from traditional purely mechanical contact tracks, not only reducing friction loss and energy consumption but also improving the stability and safety of train operation, meeting the demands of high-speed transportation in a vacuum environment.

[0020] 3. The vacuum double-layer maglev-rolling train track system disclosed in this utility model features a simple and reliable vacuum-atmospheric pressure isolation design with good engineering adaptability. Specifically, the internal pipeline system is a vacuum channel, while the external system is an atmospheric pressure maintenance space. By coating the inner and outer surfaces of the cement structure with a polymer sealing film, effective isolation between the vacuum and atmospheric pressure environments is achieved, ensuring long-term stability of airtightness and vacuum level. This structure is compatible with existing track tunnel construction methods and is particularly suitable for underground rail transit systems. The vacuum pipeline can be modified and deployed simply by adding a sealing film to the surface of the existing pipeline structure, significantly reducing engineering costs and construction complexity.

[0021] 4. The vacuum double-layer maglev-rolling train track system disclosed in this utility model adopts a modular segmented assembly structure for both the pipeline and the track assembly. Each module is sealed with an elastic sealing structure to ensure the continuity and sealing of the vacuum area, and facilitates the expansion, replacement or maintenance of the track system, enabling large-scale deployment of the vacuum track system.

[0028] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0029] like Figure 1 The vacuum double-layer maglev-rolling train track system shown is arranged as a whole in an integrated cylindrical pipe 2, and mainly consists of the outer ring of the pipe, the middle partition wall 22, the main load-bearing wall 23 and the auxiliary walls.

[0030] Pipeline 2 is fixed to the foundation and possesses pressure-bearing and high-strength structural properties. Inside pipeline 2, two vertical main load-bearing walls 23 and a partition wall 22 between them divide the space into two independent vacuum channels, namely the upper channel 24 and the lower channel 25, to meet the high-speed forward and reverse operation requirements of the train. These two rectangular channels are vacuum environments, while the remaining structural areas are under normal pressure. The main load-bearing walls 23 are fixedly connected to the corresponding inner walls of pipeline 2 via auxiliary walls, increasing the supporting strength of the main load-bearing walls 23. Specifically, the outer sides of the main load-bearing walls 23 containing the upper channel 24 and lower channel 25 are fixedly connected to the corresponding inner walls of pipeline 2 via auxiliary walls. The auxiliary walls, through a rationally designed cross-sectional shape, can effectively reduce the structural weight while improving overall stiffness and fatigue resistance.

[0031] Two vertically arranged main load-bearing walls 23 are installed inside the pipe 2, on the left and right sides respectively. The main load-bearing walls 23 are connected to the inner ring of the pipe 2 as the key load-bearing structures on both sides of the pipe 2. They are used to bear the pressure at the top of the tunnel and serve as the installation foundation for the track assembly 1. The pressure is evenly transferred to the foundation through the wall structure, thereby reducing the stress intensity per unit area at the top and bottom of the pipe 2 and improving the safety and durability of the entire pipe structure.

[0032] like Figure 3 As shown, pipe 2 is an integral cylindrical structure, installed on the surface or underground. This figure is a schematic cross-sectional view of pipe 2, demonstrating the internal zoning and load-bearing structure of the system. Pipe 2 is surrounded by an outer ring 21, constructed of reinforced concrete, providing overall structural support.

[0033] The track assembly 1 is symmetrically arranged on the left and right sides of the main load-bearing wall 23. Each track assembly 1 evenly includes an upper track 11 and a lower track 12 installed on the main load-bearing wall 23. Each track assembly 1 is installed on the inner side of the main load-bearing wall 23, corresponding to the upper passage 24 and the lower passage 25 respectively, forming the load-bearing structure for train operation. The main load-bearing wall 23 not only supports the tracks, but also serves as structural isolation and load transfer.

[0034] Within each level of the upper passageway 24 and lower passageway 25, separated by the central partition wall 22, a set of track assemblies 1 is installed on the main load-bearing walls 23 on both the left and right sides to support and guide the train carriages 3. The track assemblies 1 are arranged vertically and installed perpendicular to the main load-bearing walls 23, allowing the train to operate in a "side-mounted" manner within the passageway. This arrangement differs from the traditional flat track structure and is more suitable for high-density, bidirectional, and independent traffic needs in a vacuum environment.

[0035] like Figure 2As shown, track group 1 adopts a structure with upper and lower pairs arranged in pairs. The figure shows a single-sided track structure, including an upper track 11 and a lower track 12 installed on the main load-bearing wall 23. Each track is a long strip structure with a rectangular cross-section. The width and thickness of the track are designed to match the train specifications.

[0036] Magnets 13 are embedded in the lower surface of the upper track 11 to form a counter-magnetic field with the train's magnetic levitation structure, thereby achieving non-contact levitation load-bearing. This generates strong magnetic force to support 90% of the weight of the train carriage 3, reducing mechanical contact and improving system energy efficiency and operational stability. Specific parameters can be adjusted according to the train's operating conditions. Rolling elements 14 are installed on the upper surface of the lower track 12, using an embedded multi-point arrangement. These rolling elements can be ball bearings or roller bearings, primarily used for guidance and supporting residual loads during train operation, forming a composite load-bearing system combining magnetic levitation and rolling. This ensures both efficient magnetic levitation load-bearing and improved system stability and safety. The materials and structures of the rolling elements can be designed in various ways to balance guiding accuracy and wear resistance, ensuring the train's safety and stability during high-speed operation.

[0037] A certain distance is maintained between the upper rail 11 and the lower rail 12, allowing the wing structures on both sides of the train to be embedded within them, achieving non-contact or semi-contact support, stable guidance, and buoyancy distribution. This also further reduces frictional resistance, extends system life, and improves the stability of the train during high-speed operation. The upper and lower rail structures are fixed to the main load-bearing wall 23, possessing high rigidity and deformation resistance, suitable for high-speed operation in a vacuum environment. Slots are provided on opposite sides of the main load-bearing wall 23, into which the upper rail 11 and lower rail 12 of the corresponding rail group 1 are inserted and fixedly connected to the main load-bearing wall 23 by bolts, rivets, or clamps.

[0038] To maintain the vacuum level inside the passageways, the wall surfaces corresponding to the upper vacuum passageway 24 and the lower vacuum passageway 25, including the main load-bearing wall 23, the upper partition wall, the middle partition wall 22, the lower partition wall, and the adjacent sealing walls, are all coated with a polymer sealing material. This material has excellent airtightness and pressure resistance, effectively isolating gas exchange between the vacuum area and the normal pressure environment, ensuring the low-resistance space required for train operation. Except for the vacuum areas containing the upper and lower passageways 24 and 25, the remaining part of the interior of pipe 2 is a normal pressure air area, used for the maintenance and repair of pipe 2 and track assembly 1.

[0039] This structure simplifies the overall piping structure while ensuring the stability of the vacuum environment through the rational arrangement of vacuum and atmospheric pressure zones. The frame structure consisting of the vertical main load-bearing wall 23 and the intermediate partition wall 22 not only facilitates pressure distribution but also provides clear functional zoning, making maintenance and future modular expansion easier.

[0040] In this vacuum double-layer maglev-rolling train track system, the pipe 2 installed on the ground or underground, the main load-bearing wall 23 installed inside the pipe 2, and the track assembly 1 installed on the main load-bearing wall 23 all adopt a modular segmented assembly structure. Metal gaskets or metal lip seals are laid along the end face between each module and are fixed by external rigid pressure plates or bolt frames to form an elastic sealing structure, so as to ensure the continuity and sealing of the vacuum area and facilitate the expansion, replacement or maintenance of the system.

[0041] The train operates bidirectionally within each level of the upper passageway 24 and lower passageway 25, separated by the main load-bearing wall 23 and the intermediate partition wall 22. This arrangement saves more space compared to the traditional horizontal layout. Simultaneously, the vertical and lateral loads generated during train operation are sequentially transferred to the main load-bearing wall 23 via the tracks, and then from the main load-bearing wall 23 to the foundation structure, thereby improving the overall structural stability and load-bearing reliability. During train operation, 90% of the train's weight is non-contactly levitated by magnets 13 embedded in the lower surface of the upper track 11. The rolling elements 14 on the upper surface of the lower track 12 are mainly used for guidance and support of the remaining load during train operation, forming a composite load-bearing system combining magnetic levitation and rolling.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
