Description

Technical Field

[0001] This invention relates to the field of maglev transportation technology, and in particular to modular maglev track slab assemblies, track structure assemblies, and maglev transportation systems. Background Technology

[0002] High-speed maglev transportation systems utilize electromagnetic force to levitate and guide trains, eliminating wheel-rail contact during operation and thus avoiding traditional wheel-rail friction. This offers advantages such as high safety, environmental friendliness, low overall cost, and flexible route selection. However, the large-scale application of this system is constrained by the high cost of its track structure.

[0003] Currently, the track structure of common high-speed maglev transportation systems mainly consists of a combination of track beams, track supports, and track panels. This structure has the following prominent drawbacks: First, the structure is complex, involving the combination and installation of multiple components, which increases the difficulty and time cost of construction; second, due to the large number of components, the cost of raw materials, manufacturing, installation, and maintenance is high, with the asymmetrical irregular structure of the induction guide rail leading to high processing costs.

[0004] Since the track structure is the foundation and main cost component of a high-speed maglev transportation system, the aforementioned structural complexity and high cost have become key bottlenecks hindering the large-scale commercial promotion of high-speed maglev transportation technology.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] It should be noted that when a component is referred to as "mounted on", "fixed on", or "set on" another component, it can be directly on or indirectly set on the other component; when a component is referred to as "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0024] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.

[0025] This invention provides a modular maglev track slab assembly, comprising a prefabricated track slab and a guide rail assembly. Embedded mounting components for mounting the guide rail assembly are pre-embedded within the prefabricated track slab, and the guide rail assembly is mounted on the embedded mounting components. The guide rail assembly is mounted on both sides of the lower surface of the prefabricated track slab, with the extension direction of the guide rail assembly parallel to the extension direction of the prefabricated track slab. The guide rail assembly includes a guide rail and a linear motor induction plate. A cavity is formed in the upper surface of the guide rail, and the linear motor induction plate is mounted within the guide rail. This modular maglev track slab assembly, through the combination of the prefabricated track slab and the guide rail assembly, achieves the functions of levitation, guidance, and traction for maglev trains, greatly simplifying the structure of the track system. Furthermore, with the optimization and improvement of the overall structure, the clearance dimensions of the track system are further reduced, thus reducing overall engineering investment. Furthermore, the use of prefabricated track slabs enables standardized factory prefabrication, facilitating large-scale production and effectively reducing production costs. The simple structure of the guide rail assembly also reduces manufacturing and installation costs. Simultaneously, due to the simplified structure, subsequent maintenance costs are correspondingly reduced. The prefabricated track slabs can be transported to the construction site for installation after factory prefabrication, reducing on-site construction time and workload, and improving construction efficiency.

[0026] Please refer to the following: Figures 1 to 6 In one embodiment, a modular maglev track slab assembly 100 is provided, specifically a modular fast maglev track slab assembly applied in a high-speed maglev transportation system. The modular maglev track slab assembly 100 primarily aims to reduce the engineering cost of the track structure and enhance the market competitiveness of maglev transportation technology.

[0027] The modular maglev track assembly 100 includes a prefabricated track slab 10 and a guide rail assembly 20. The prefabricated track slab 10 has embedded mounting parts 11 for mounting the guide rail assembly 20, and the guide rail assembly 20 is mounted on the embedded mounting parts 11. The guide rail assemblies 20 are mounted on both sides of the lower surface of the prefabricated track slab 10. It should be noted that in this application, the lower surface and upper surface of a component refer to two opposing surfaces of that component. When the modular maglev track assembly 100 is installed, the lower surface is the surface relatively closer to the ground, while the upper surface is the surface relatively farther from the ground. For example, as... Figure 2 As shown, the lower surface of the prefabricated track slab 10 refers to the surface located on the lower side, and the upper surface of the prefabricated track slab 10 refers to the surface located on the upper side. The extension direction of the guide rail assembly 20 is parallel to the extension direction of the prefabricated track slab 10.

[0028] The guide rail assembly 20 includes a guide rail 21 and a linear motor induction plate 22. The guide rail 21 is mainly used to generate levitation force by interacting with an electromagnet to achieve levitation guidance of the train. A cavity 211 is formed on the upper surface of the guide rail 21, and the linear motor induction plate 22 is installed in the guide rail 21.

[0029] Understandably, the track structure of existing high-speed maglev transportation systems is mainly composed of track beams, track supports, and track panels. The structure is complex, involving the combination and installation of multiple components, which increases the difficulty and time cost of construction. Furthermore, due to the large number of components, the cost of raw materials, manufacturing, installation, and maintenance is relatively high.

[0030] The modular maglev track assembly 100 provided in this embodiment achieves the functions of levitation, guidance, and traction of the maglev train simply by combining the prefabricated track slab 10 and the guide rail assembly 20, greatly simplifying the structure of the track system. Furthermore, with the optimization and improvement of the overall structure, the clearance dimensions of the track system are further reduced, decreasing overall project investment. In addition, the prefabricated track slab 10 can be prefabricated and transported to the construction site for installation after factory prefabrication, reducing on-site construction time and workload and improving construction efficiency. The prefabricated track slab 10 can be factory-standardized prefabrication, enabling large-scale production and effectively reducing production costs. The simple structure of the guide rail assembly 20 also reduces manufacturing and installation costs. Simultaneously, due to the simplified structure, subsequent maintenance costs are correspondingly reduced. The linear motor induction plate 22 is directly installed within the guide rail 21, eliminating the need to reserve installation positions for the linear motor induction plate 22 on the prefabricated track slab 10. This also allows for the overall installation of the guide rail assembly 20, further reducing manufacturing and installation difficulty. Furthermore, the guide rail 21 has a recess 211, which can cooperate with the corresponding structure on the prefabricated track slab 10 to achieve positioning and force distribution during installation, reduce installation difficulty, and improve the stability of the guide rail 21 after installation.

[0031] Specifically, in one embodiment, the guide rail assembly 20 is mounted on both sides of the lower surface of the prefabricated track plate 10.

[0032] Preferably, in one embodiment, the guide rail 21 includes a first rail body 212 and extended rail bodies 213 symmetrically arranged on both sides of the first rail body 212, and the cavity 211 is located above the first rail body 212. That is, in this embodiment, the guide rail 21 has a symmetrical structure, which can reduce the processing difficulty and processing cost.

[0033] Preferably, in one embodiment, the extended track 213 includes a second track 2131, a third track 2132, and a fourth track 2133. One side of the second track 2131 is connected to the first track 212, and the second track 2131 is inclined upwards relative to the first track 212. It should be noted that "inclined upwards" refers to inclination relative to the side facing the upper surface, while "inclined downwards" refers to inclination relative to the side facing the lower surface. One side of the third track 2132 is connected to the other side of the second track 2131, and the third track 2132 is inclined downwards relative to the second track 2131. One side of the fourth track 2133 is connected to the other side of the third track 2132, and the fourth track 2133 is inclined downwards relative to the third track 2132. The first track 212 and the two second tracks 2131 together form the cavity 211.

[0034] Specifically, in one embodiment, the third rail 2132 is arranged parallel to the first rail 212, and the fourth rail 2133 is arranged perpendicular to the third rail 2132. That is, in this embodiment, the guide rail 21 has an overall "M" shape, and is an M-shaped guide rail. More specifically, the second rail 2131 is tilted upwards at an angle less than 90° relative to the first rail 212.

[0035] It is understandable that the linear motor sensing plate 22 is directly integrated into the guide rail 21. The lower surface of the linear motor sensing plate 22 and the lower surface of the guide rail 21 need to be in the same plane. If a "U"-shaped guide rail design is adopted, the linear motor sensing plate 22 and the guide rail 21 are suspended, which is prone to deformation and collision under the normal force of the motor. However, in this embodiment, the guide rail 21 adopts an "M"-shaped structure, and the linear motor sensing plate 22 is directly fixed on the protruding structure in the middle of the guide rail 21, forming an integral structure, which makes the force distribution more reasonable.

[0036] The guide rail 21 can be assembled from multiple bent M-shaped thin steel plates, or it can be stamped or bent from a single steel plate of the same thickness.

[0037] Specifically, in one embodiment, the pre-embedded mounting component 11 is a pre-embedded tapered threaded sleeve. The guide rail 21 is mounted on the prefabricated track slab 10 by engaging the pre-embedded tapered threaded sleeve with a bolt 30. The pre-embedded tapered threaded sleeve can be made of stainless steel or a composite pre-embedded sleeve made of PVC or other composite materials. More specifically, the third rail body 2132 is provided with mounting holes to avoid the bolt 30. The head of the bolt 30 abuts against the lower surface of the third rail body 2132, thereby fastening the guide rail 21 to the prefabricated track slab 10. Each guide rail 21 has two corresponding third rail bodies 2132 with bolts 30 installed, thus better ensuring the stability of the guide rail 21 installation.

[0038] Preferably, in one embodiment, the lower surface of the prefabricated track slab 10 is provided with a protruding structure 12 that matches the recessed cavity 211. That is, in this embodiment, the protruding structure 12 is provided at the position on the lower surface of the prefabricated track slab 10 where the guide rail 21 is installed, and the shape of the protruding structure 12 matches the recessed cavity 211, so that when the guide rail 21 is installed on the prefabricated track slab 10, the recessed cavity 211 and the protruding structure 12 can coincide. Through the cooperation between the protruding structure 12 and the recessed cavity 211, the installation and positioning of the guide rail 21 can be achieved, reducing installation difficulty. It can also be used to distribute the lateral forces on the guide rail 21, improving the stability of the guide rail 21.

[0039] Specifically, in one embodiment, the upper surface of the third track body 2132 is attached to the lower surface of the prefabricated track slab 10, and the upper surfaces of the second track body 2131 and the first track body 212 are attached to the surface of the protruding structure 12.

[0040] Preferably, in one embodiment, the linear motor induction plate 22 includes an iron core 221 and an aluminum plate 222, wherein the aluminum plate 222 is located below the iron core 221 and is connected to the iron core 221.

[0041] Specifically, in one embodiment, the iron core 221 is a π-shaped iron core, and the lower surface of the aluminum plate 222 is parallel to the lower surface of the guide rail 21. More specifically, the lower surface of the aluminum plate 222 is flush with the lower surface of the fourth rail body 2133.

[0042] The aluminum plate 222 and the iron core 221 can be connected by bolts, or they can be fixed by welding, gluing or other methods.

[0043] Preferably, in one embodiment, both the iron core 221 and the aluminum plate 222 have symmetrical structures, thereby reducing processing difficulty and cost. Specifically, the iron core 221 includes an iron core body portion 2211 and iron core extension portions 2212 symmetrically arranged on both sides of the iron core body portion 2211. The aluminum plate 222 includes an aluminum plate body portion 2221 and aluminum plate extension portions 2222 symmetrically arranged on both sides of the aluminum plate body portion 2221.

[0044] More specifically, in one embodiment, the core extension 2212 includes a first core extension 22121 and a second core extension 22122. One side of the first core extension 22121 is connected to the core body 2211, and the first core extension 22121 is inclined upward relative to the core body 2211. One side of the second core extension 22122 is connected to the other side of the first core extension 22121, and the second core extension 22122 is inclined downward relative to the first core extension 22121. The core body 2211 is parallel to the first rail 212, and the upper surface of the core body 2211 is in contact with the lower surface of the first rail 212. The first core extension 22121 is parallel to the second rail 2131, and the upper surface of the first core extension 22121 is in contact with the lower surface of the second rail 2131. The second extension 22122 of the iron core is parallel to the third rail 2132, and the upper surface of the second extension 22122 is in contact with the lower surface of the third rail 2132. This structure can better ensure the reliability of the connection between the iron core 221 and the guide rail 21.

[0045] The aluminum plate body portion 2221 is parallel to the iron core body portion 2211, and the upper surface of the aluminum plate body portion 2221 is in contact with the lower surface of the iron core body portion 2211. The aluminum plate extension portion 2222 is parallel to the first iron core extension portion 22121, and the upper surface of the aluminum plate extension portion 2222 is in contact with the lower surface of the first iron core extension portion 22121. This structure better ensures the reliability of the connection between the aluminum plate 222 and the iron core 221.

[0046] In other words, in this embodiment, both the iron core 221 and the aluminum plate 222 are bent structures that match the guide rail 21 of the “M” structure. Through this structural design, the mounting hole positions of the guide rail 21 of the “M” structure can be fully utilized and fixed based on the same mounting hole.

[0047] Preferably, in one embodiment, the linear motor induction plate 22 is fixedly connected to the guide rail 21 by fixing bolts, thereby improving the stability of the connection.

[0048] Specifically, in one embodiment, the fixing bolts are located at the first extension portion 22121 of the iron core and the extension portion 2222 of the aluminum plate. The first extension portion 22121 of the iron core and the extension portion 2222 of the aluminum plate are respectively provided with mounting holes to avoid the fixing bolts. This structural design ensures both the reliability of the linear motor induction plate 22 installation and the stability of the performance of the iron core 221 and the aluminum plate 222. More specifically, both the first extension portion 22121 of the iron core and the extension portion 2222 of the aluminum plate on both sides are provided with mounting holes to avoid the fixing bolts, so that the linear motor induction plate 22 and the guide rail 21 can be fixed together by two rows of fixing bolts. It is understood that because a large suction force is generated between the motor and the aluminum plate 222 during motor operation, two rows of fixing bolts are used to prevent the aluminum plate 222 from bulging, deforming, or falling off.

[0049] To further improve the traction efficiency of the traction motor, preferably, in one embodiment, such as Figure 6 As shown, the aluminum plate 222 adopts a slotted grid structure. That is, in this embodiment, the aluminum plate 222 is no longer a single plate structure, but rather has multiple slots formed on it, making the aluminum plate 222 present a grid structure as a whole.

[0050] Preferably, in one embodiment, the upper surface of the prefabricated track slab 10 is provided with pre-embedded screw holes, which are mainly used for the installation and arrangement of equipment in electromechanical systems, etc., to facilitate the installation of subsequent equipment.

[0051] Preferably, in one embodiment, the precast track slab 10 includes a concrete slab 13, embedded reinforcing bars 14, and a skid layer 15. The concrete slab 13 has pre-drilled holes 131 inside, and the embedded reinforcing bars 14 are disposed within the concrete slab 13. The concrete slab 13 is a prestressed and non-prestressed structure. The pre-drilled holes 131 are used for connection with the substructure of the bridge, facilitating the connection and fixation of the concrete slab 13 to the bridge during on-site construction. Skid layers 15 are provided on both sides of the upper surface of the concrete slab 13, extending along the length of the concrete slab 13. The skid layers 15 are mainly used when the train alights or in emergency situations, effectively distributing the weight of the train through sliding and providing temporary support to prevent excessive tilting or damage to the track structure.

[0052] The skid layer 15 can be made of materials that meet the friction coefficient requirements, such as concrete, steel fiber concrete, or steel structure.

[0053] Preferably, in one embodiment, the skid layer 15 has pre-drilled holes for arranging heating cables, so that heating cables can be arranged in the skid layer 15, thereby preventing the skid layer 15 from freezing in winter and avoiding the problem of train brake failure.

[0054] Compared with existing technologies, the modular magnetic levitation track assembly 100 has the following advantages: 1. Simple structure: The modular maglev track slab assembly 100 realizes the functions of maglev train suspension, guidance and traction by combining the prefabricated track slab 10 and the guide rail assembly 20, which greatly simplifies the structure of the track system. At the same time, with the optimization and improvement of the overall structure, the limit size of the track system is further reduced, and the overall project investment is reduced.

[0055] 2. Cost Reduction: The prefabricated track slab 10 is manufactured using standardized factory prefabrication, enabling large-scale production and effectively reducing production costs. The simple structure of the guide rail assembly 20 also reduces manufacturing and installation costs. Furthermore, due to the simplified structure, subsequent maintenance costs are correspondingly reduced.

[0056] 3. Convenient construction: The prefabricated track slab 10 can be transported to the construction site for installation after being prefabricated in the factory, which reduces the time and workload of on-site construction and improves construction efficiency.

[0057] Please refer to the following: Figures 7 to 9 Meanwhile, in one embodiment, a track structure assembly 1000 is also provided, specifically a modular high-speed maglev track structure assembly. The track structure assembly 1000 includes a track beam 200 and the modular maglev track slab assembly 100, the modular maglev track slab assembly 100 being disposed on the track beam 200.

[0058] Specifically, in one embodiment, the cross-section of the track beam 200 is generally U-shaped, and the track beam 200 is a U-shaped track beam. Of course, in other embodiments, the track beam 200 can also adopt a closed cavity design in addition to the U-shaped open design.

[0059] Specifically, the track beam 200 is a prestressed concrete structure. The track beam 200 and the modular maglev track slab assembly 100 are fixedly connected by post-casting. That is, in this embodiment, the modular maglev track slab assembly 100 is assembled onto the track beam 200 by post-casting. Specifically, casting can be performed through the pre-reserved post-casting holes 131 on the concrete slab 13, thereby fixing the concrete slab 13 onto the track beam 200 and achieving a fixed connection between the modular maglev track slab assembly 100 and the track beam 200.

[0060] In other embodiments, in addition to the post-cast connection and assembly method, the track beam 200 and the modular maglev track slab assembly 100 can also be designed to be integrally cast in one piece.

[0061] Specifically, each set of track beams 200 is provided with multiple sets of modular magnetic levitation track slab assemblies 100 in sequence, and the multiple sets of modular magnetic levitation track slab assemblies 100 and the track beams 200 form a complete track structure assembly 1000.

[0062] Meanwhile, in one embodiment, a maglev transportation system is also provided, which utilizes the modular maglev track slab assembly 100 or the track structure assembly 1000.

[0063] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
