Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic turnouts, and in particular to a high-speed magnetic levitation electromagnetic turnout and a control method thereof. Background Art

[0002] With the rapid development of high-speed maglev technology, high-speed maglev trains, owing to their advantages such as high speed, low noise, and low friction, are becoming an important direction for future rail transportation. However, existing high-speed maglev trains face numerous technical challenges in the track switching process. Traditional turnout systems primarily rely on mechanical switching technology, which is relatively backward in the track switching of high-speed maglev trains. These technologies are primarily characterized by long track switching times, complex structures, and severe mechanical wear, making them difficult to meet the requirements of high-speed operation.

[0011] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0012] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are used only to distinguish the description and should not be understood as indicating or implying relative importance.

[0013] Example 1: See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 This embodiment provides a high-speed magnetic levitation electromagnetic turnout, including: A first track 1, wherein the first track 1 is a straight track; The second track 2 is a straight track, the center lines of the second track 2 and the first track 1 are the same straight line, and a gap is set between the second track 2 and the first track 1; a third track 3, the third track 3 being arranged on one side of the second track 2, with a gap being provided between the third track 3 and the first track 1; Auxiliary rails 4 are arranged on both sides of the second rail 2 and the third rail 3. The auxiliary rails 4 are used to provide lateral thrust and suspension force when the high-speed maglev train 11 passes through the first rail 1 and travels to the second rail 2 or the third rail 3, so that the train automatically changes tracks.

[0014] In this step, both the first track 1 and the second track 2 are straight tracks, and their centerlines are aligned, but a gap exists between them. This design helps the high-speed maglev train maintain stable straight-line travel when track changes are not required, while also providing structural feasibility for subsequent track changes. The third track 3 is located to one side of the second track 2 and also has a gap between it and the first track. This layout allows for flexible travel path options for the train. The gap is designed to avoid mechanical interference during high-speed operation and ensure that the high-speed maglev train can smoothly transition from one track to the other.

[0015] The design of the auxiliary rails 4 plays a core role in this system. They are arranged on both sides of the second rail 2 and the third rail 3, and their main function is to provide lateral thrust and suspension force for the train during the track changing process. This design utilizes electric suspension technology, and forms an electromagnetic force with the aluminum alloy plates on the high-speed maglev train through the suspension permanent magnets and guide permanent magnets configured on the auxiliary rails. When the train needs to switch from the first track to the second track or the third track, the auxiliary rails 4 and the guide electromagnets 9 simultaneously provide sufficient lateral thrust to guide the train to change tracks, and provide suspension force to ensure that the train maintains a stable suspension state throughout the process. This method avoids the mechanical wear and switching delay problems caused by traditional mechanical switches, making the track changing process smoother and more efficient.

[0016] Furthermore, this electromagnetically assisted track-changing technology is well-suited for high-speed applications. The contactless electromagnetic guidance provided by the auxiliary track 4 not only reduces system friction but also significantly improves the response speed and reliability of track changes, ensuring smooth path switching at high speeds. Overall, this design, through its highly efficient electromagnetic assistance system, effectively improves the stability, safety, and efficiency of track changes for high-speed maglev trains.

[0017] Among them, the auxiliary track 4 includes an auxiliary track frame 5, a suspended permanent magnet 6 and a guide permanent magnet 7. The auxiliary track frame 5 is arranged on both sides of the second track 2 or the third track 3, and the track frame is arranged on the track beam of the second track 2 or the third track 3. The auxiliary track frame 5 is arranged in an L shape, and the suspended permanent magnet 6 and the guide permanent magnet 7 are both arranged on the auxiliary track frame 5.

[0018] It is understood that the auxiliary track 4 is composed of an auxiliary track frame 5, a suspension permanent magnet 6, and a guide permanent magnet 7, which together provide stable suspension and guidance functions for the high-speed maglev train's track-changing process. The auxiliary track frame 5 is installed on both sides of the second track 2 or the third track 3, and provides stable support with the help of the track beam structure to ensure the stability and load-bearing capacity of the entire auxiliary system. The auxiliary track frame 5 adopts an L-shaped structure. The advantage of this design is that it can make full use of space and facilitate the reasonable layout of the suspension permanent magnet 6 and the guide permanent magnet 7 on the side and bottom of the track, thereby providing the best electromagnetic auxiliary effect when the high-speed maglev train changes tracks.

[0019] Suspension permanent magnets 6 are fixed to the upper surface of the inner bottom of the auxiliary track frame 5. Their primary function is to provide levitation for the maglev train. As the train passes, the relative motion between the suspension permanent magnets 6 and the aluminum alloy plate at the train's base generates a magnetic force that keeps the train suspended during the track change process, avoiding physical contact and mechanical friction, thereby achieving a smooth, contactless track change. This suspension design is crucial for maintaining the stability of high-speed maglev trains and effectively reduces vibrations caused by track changes.

[0020] Guide permanent magnets 7 are mounted on the inner sidewalls of the auxiliary track frame 5 to provide lateral guidance for the train. During high-speed track changes, the guide permanent magnets 7 interact with the aluminum alloy plates on the train's sidewalls, generating magnetic force to guide the train onto the intended track. This design precisely controls the train's lateral position, preventing lateral deviation during the track change process and effectively improving safety and accuracy.

[0021] The suspension frame of the high-speed maglev train 11 is provided with at least two groups of aluminum alloy plates 8 , and the two groups of aluminum alloy plates 8 are respectively provided on the side wall and the bottom of the suspension frame.

[0022] It is understood that at least two sets of aluminum alloy plates 8 are installed on the suspension frame of the high-speed maglev train 11. This design is designed to work in conjunction with the suspension permanent magnets 6 and guide permanent magnets 7 on the auxiliary track 4 during the track change process, providing levitation and lateral guidance force, ensuring a smooth and safe track change for the train. Specifically, the two sets of aluminum alloy plates 8 are installed on the side walls and bottom of the suspension frame, respectively, and are rationally distributed to meet the dual requirements of levitation and guidance.

[0023] The aluminum alloy plate 8 at the bottom of the suspension frame primarily interacts with the levitation permanent magnet 6 at the bottom of the auxiliary track frame 5. The high-speed maglev system uses the principle of electromagnetic induction to generate an induced current between the aluminum alloy plate and the levitation permanent magnet, thereby generating a Lorentz force that levitates the train above the track. This contactless levitation method significantly reduces friction and energy loss, helping the train maintain a stable levitation state during high-speed operation. Furthermore, due to the excellent conductivity and lightweight properties of aluminum alloy, it can effectively reduce the train's deadweight while ensuring the responsiveness and efficiency of the turnout system.

[0024] Aluminum alloy plates 8 mounted on the side walls of the suspension frame work in conjunction with guide permanent magnets 7 on the side walls of the auxiliary track frame 5 to provide lateral guidance. During track switching, when the train transitions from the first track 1 to the second track 2 or the third track 3, the magnetic field generated by the guide permanent magnets 7 acts on the aluminum alloy plates 8 on the side walls, guiding the train toward the target track through electromagnetic force. This design ensures that the train maintains precise lateral positioning during track switching, avoiding the risk of drift or derailment due to inertia at high speeds.

[0025] Among them, the suspension permanent magnet 6 is arranged on the upper surface of the inner side of the bottom of the auxiliary track frame 5, and the suspension permanent magnet 6 and the aluminum alloy plate 8 at the bottom of the high-speed maglev train 11 are arranged correspondingly. The guide permanent magnet 7 is arranged on the inner wall of the auxiliary track frame 5, and the guide permanent magnet 7 and the aluminum alloy plate 8 on the side wall of the high-speed maglev train 11 are arranged correspondingly.

[0026] It should be understood that the levitation permanent magnet 6 in this step is installed on the upper surface of the inner bottom of the auxiliary track frame 5. Its primary function is to provide stable levitation for the train. When the train passes at high speed, the levitation permanent magnet 6 interacts with the aluminum alloy plate 8 at the bottom of the train, generating an opposing magnetic field through electromagnetic induction, creating sufficient levitation force to lift the train and suspend it above the track. This contactless levitation not only eliminates mechanical friction but also significantly reduces energy loss and system wear, thereby improving the system's durability and operational efficiency.

[0027] The guide permanent magnets 7 are mounted on the inner sidewalls of the auxiliary track frame 5 to provide lateral guidance for the train. During track switching, the guide permanent magnets 7 interact with the aluminum alloy plates 8 on the sidewalls of the high-speed maglev train, generating a lateral magnetic field force. This lateral guidance force accurately guides the train smoothly toward the target track, effectively preventing it from drifting due to inertia or lateral forces during high-speed travel and track switching. This design significantly improves train stability and safety during high-speed track switching.

[0028] This layout of the suspension and guidance system offers multiple technical advantages. First, the rational distribution of the suspension and guidance permanent magnets enables independent control of the suspension and guidance functions, allowing the system to flexibly adjust the magnetic field distribution during different operating phases (such as straight-line travel and track changes). Second, this structure responds quickly in high-speed scenarios, adjusting the suspension and guidance forces within milliseconds through electromagnetic induction, meeting the real-time and high-precision requirements of high-speed maglev trains. Furthermore, compared to traditional mechanical contact switches, contactless magnetic guidance reduces mechanical wear and vibration, improving system durability and ease of maintenance.

[0029] The high-speed maglev train 11 is provided with guide electromagnets 9 , and at least one group of guide electromagnets 9 is provided. The guide electromagnets 9 are provided at positions corresponding to the aluminum alloy plates 8 on the side walls of the high-speed maglev train 11 .

[0030] It can be understood that the function of the guide electromagnet 9 is to provide additional lateral guidance force during high-speed operation and track switching, ensuring that the train can smoothly travel along the predetermined track. This design further improves the train's lateral stability and track switching accuracy, especially in complex high-speed scenarios, and can effectively resist the influence of lateral disturbances and inertial forces.

[0031] At least one set of guide electromagnets 9 is provided, and multiple sets may be provided to enhance guidance, depending on the train's operating conditions and safety requirements. These electromagnets, operating on the principle of electromagnetic induction, can rapidly adjust the magnetic field strength and direction when needed, interacting with the guide permanent magnets 7 on the auxiliary rails 4. When the train approaches a switch or undergoes a track change, the guide electromagnets 9 activate, generating a controllable transverse magnetic field that interacts with the sidewall aluminum alloy plates 8 to generate a magnetic force. This magnetic force precisely guides the train to its target track while maintaining its balance and preventing lateral deviation or vibration caused by high-speed travel.

[0032] Electromagnetic guidance systems offer significant advantages over traditional mechanical guidance systems. First, electromagnets can dynamically adjust the guidance force based on the train's operating status, thereby improving the flexibility and responsiveness of guidance control. Second, electromagnetic guidance eliminates the need for physical contact, reducing mechanical wear, extending system life, and lowering maintenance costs. Furthermore, during the operation of high-speed maglev trains, this electromagnetic guidance system enables high-precision, real-time control, helping to enhance train safety and operational smoothness.

[0033] The high-speed maglev train 11 is provided with levitation electromagnets 10 . There is at least one group of levitation electromagnets 10 . The levitation electromagnets 10 are arranged at positions corresponding to the aluminum alloy plate 8 at the bottom of the high-speed maglev train 11 .

[0034] It is understood that during the operation of a high-speed maglev train, especially when passing through switches or performing high-speed track changes, the train's bottom may be subjected to uneven forces or external disturbances. In these situations, the levitation electromagnets 10 can rapidly adjust the current to maintain a stable levitation height and posture. The configuration of at least one set of levitation electromagnets allows the system to provide levitation force to different areas of the train bottom as needed, achieving more precise levitation control. Furthermore, the coordinated operation of multiple levitation electromagnets can disperse the levitation load, reduce single-point forces, and improve the reliability and durability of the system.

[0035] The gap between the second track 2 and the first track 1 is greater than 0.3 meters, and the gap between the third track 3 and the first track 1 is greater than 0.3 meters.

[0036] It is understood that a gap greater than 0.3 meters ensures sufficient space for safe lateral movement and suspension adjustment when the high-speed maglev train 11 switches tracks. Because maglev trains experience significant inertia and dynamic vibrations at high speeds, a gap that is too small can easily interfere with adjacent tracks during the track change process, leading to system instability or track change failure. A gap greater than 0.3 meters provides ample buffer space, allowing the train to smoothly switch from the first track 1 to the second track 2 or the third track 3, thanks to the lateral thrust and guiding force provided by the auxiliary track 4.

[0037] The auxiliary tracks 4 on both sides of the second track 2 and the third track 3 are both longer than 20 meters and shorter than 25 meters.

[0038] It is understandable that the length of the auxiliary rail 4 is between 20 meters and 25 meters, which can provide continuous and stable lateral thrust and suspension force. During the track switching process of high-speed maglev trains, due to the extremely high speed of the train, the auxiliary rail is required to provide a sufficiently long action range to ensure a smooth transition of thrust and suspension force. If the auxiliary rail is too short, the train may not be able to obtain sufficient lateral guidance during the track switching process, resulting in unstable or failed track switching; if the auxiliary rail is too long, it may increase system cost and structural complexity. Therefore, the length range of 20 meters to 25 meters achieves the best balance in technology and economy.

[0039] Example 2: See also Figure 6 This embodiment provides a method for controlling an electromagnetic turnout for a high-speed maglev system, comprising: Obtain the location information and train track information of high-speed maglev trains; Determining a high-speed maglev train travel route based on the train travel track information, and determining an auxiliary track to be passed based on the high-speed maglev train travel route; If the high-speed maglev train's route is based on switching tracks from the first track to the second track, the suspension permanent magnets and guide permanent magnets on the auxiliary tracks on both sides of the second track generate suspension force and guide force, so that the high-speed maglev train passes through the gap between the first track and the third track and travels to the second track.

[0040] It's understood that by acquiring the train's location and track information in this step, the system can track the train's operating status in real time and determine its current track and direction of travel. This information is typically acquired in real time through sensors and positioning systems (such as GPS, magnetic field sensors, or encoders), providing the basis for subsequent control decisions. For example, location information includes the train's current track segment, while track information indicates whether the train is approaching a track change area or preparing to enter a second or third track.

[0041] Based on this information, the control system determines the train's route. By monitoring the train's position in real time, the system can predict the train's next track and make appropriate control decisions. If it determines that the train will switch from the first track to the second, the control system initiates the appropriate track-changing procedure. During this process, determining the train's route is the core of the entire control method. It directly determines which side of the auxiliary track the train will pass through. By controlling the levitation electromagnets and guide electromagnets on the maglev vehicle, the levitation frame moves to the switch, generating an initial displacement. This change in displacement regulates the electric levitation force between the aluminum plate on the levitation frame and the levitation guide permanent magnets on the auxiliary track. The combined action of the electromagnetic and electric levitation structures enables the switching of operating tracks.

[0042] When the system confirms that the train needs to switch from the first track to the second track, the suspension permanent magnet will provide the train with an upward suspension force through electromagnetic action; the guide permanent magnet will provide a lateral guiding force to guide the train to accurately cross the gap between the first track and the third track and stably enter the second track.

[0043] Among them, if the high-speed maglev train's route is based on changing tracks from the first track to the third track, the suspension permanent magnets and guide permanent magnets on the auxiliary tracks on both sides of the third track generate suspension force and guide force, so that the high-speed maglev train passes through the gap between the first track and the second track and runs onto the third track.

[0044] It's understandable that when a train reaches a switch, the control system needs to determine the train's operating track and target track in real time. If the train's route is determined to switch from the first track to the third track, the system uses this information to control the levitation and guide electromagnets on the maglev vehicle, causing the levitation frame to move to the switch and generate an initial displacement. The levitation and guide permanent magnets on the auxiliary track play a key role at this point, providing levitation and guide forces, respectively, through electromagnetic interaction, to ensure a stable transition to the third track at high speeds.

[0045] During the track changing process, since the train may experience certain dynamic vibrations and lateral deviations, the suspended permanent magnets can ensure that the train is always in a suspended state, avoiding severe contact forces or unnecessary friction caused by unbalanced forces.

[0046] Permanent guide magnets provide lateral guiding force near the sidewalls of the train. This force is crucial for ensuring precise track changes. In high-speed maglev systems, trains travel at high speeds and experience significant inertia. Without sufficient guiding force, the train could deviate from the track due to inertia, resulting in a failed track change. Through precise electromagnetic control, the permanent guide magnets provide sufficient guiding force, ensuring the train smoothly and accurately passes through the gap between the first and second tracks and enters the third track. The control requirements for the permanent guide magnets are extremely high, requiring precise adjustment based on the train's current operating status, speed, and track conditions.
