Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic levitation track, in particular to a combined magnetic levitation track suitable for pipeline transportation and an application method thereof. BACKGROUND

[0002] The content of this part only provides background information related to the present application, which may not constitute prior art.

[0003] Magnetic levitation pipeline transportation is a cutting-edge transportation method that combines magnetic levitation technology with vacuum pipeline transportation. In a sealed pipeline, vehicles are suspended by electromagnetic force without contact, eliminating the frictional resistance of traditional wheel-rail systems. At the same time, they operate in a near-vacuum environment to significantly reduce air resistance. This transportation system has the characteristic of nearly silent operation and can achieve stable and efficient point-to-point transportation, like vehicles flying on invisible tracks. Its core technology lies in precisely adjusting the electromagnetic field through an intelligent control system to maintain the stable suspension of vehicles in the pipeline, while linear motors are used for acceleration and braking. This green transportation mode not only has extremely low energy consumption, but also can adapt to complex geographical environments, providing a new solution for future urban group interconnection and ultra-long distance transportation.

[0004] In the prior art, a Chinese patent with publication number CN212447129U discloses an underground low-vacuum pipeline super-speed magnetic levitation transportation system, which includes a tunnel, a sealing cover, a support structure, a rail-bearing beam, and a magnetic levitation track. The inner wall of the tunnel is provided with a lining structure. The support structure is formed by pouring reinforced concrete on the lining structure at the bottom of the tunnel. The sealing cover extends along the length direction of the tunnel and is fixedly installed at the top of the support structure. The sealing cover and the support structure are sealed by a sealing structure, and a super-speed magnetic levitation vehicle operating space is formed between the sealing cover and the support structure. The bottom of the rail-bearing beam is fixedly installed at the top of the support structure in the sealing cover. The magnetic levitation track is fixedly installed at the top of the rail-bearing beam, and the super-speed magnetic levitation vehicle is used to run along the magnetic levitation track. This transportation system operates in underground space and can be applied to urban areas and mountainous regions.

[0005] However, the above-mentioned related technology fixes the rail-bearing beam and the magnetic levitation track through the support structure, but a large amount of space in the tunnel is used to accommodate maintenance equipment, ventilation lighting, and other auxiliary facilities, resulting in an imbalance between the vehicle operating space and the cross-sectional area of the tunnel. The segmented connection method of the sealing cover and the support structure further aggravates the structural redundancy, and multiple layers of sealing materials need to be set at the segmented joints, which not only occupies effective space but also increases the risk of air tightness failure. This design cannot balance the intensive use of underground space and the anti-interference ability of the suspension system, restricting the promotion of this technology in complex urban geological conditions.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Example 1:

[0031] like Figure 1 and 2 As shown in the embodiment of this application, a combined maglev track suitable for pipeline transportation includes:

[0032] Installation pipe 1, which includes a travel channel and a horizontal load-bearing section, is connected to the inner wall of installation pipe 1. The horizontal plane of the horizontal load-bearing section is parallel to the axis of installation pipe 1. Specifically, installation pipe 1, as the load-bearing foundation of the track system, adopts an integrated design with the underground pipeline. It has an internal travel channel for maglev vehicles and a horizontal load-bearing section rigidly connected to the inner wall of the pipe, with its horizontal plane strictly parallel to the pipe axis. This integrated structure avoids the installation process of traditional prefabricated bases, ensuring connection strength and simplifying the construction process. The horizontal plane of the horizontal load-bearing section provides a precise installation reference surface for subsequent track components, ensuring the consistency of spatial positioning of each component.

[0033] Traction rail mounting base 2 and linear motor induction plate 3, such as Figure 3 As shown, the traction rail mounting base 2 is connected to the horizontal plane of the horizontal bearing section; the linear motor induction plate 3 is connected to the end of the traction rail mounting base 2 away from the horizontal bearing section. Specifically, the traction rail mounting base 2 is fixed to the lower surface of the horizontal bearing section by mechanical fastening (such as bolts), and its bottom is connected to the linear motor induction plate 3. The linear motor induction plate 3 forms an electromagnetic coupling with the mover of the vehicle-mounted linear motor, generating thrust through the traveling wave magnetic field when the vehicle is running. In particular, the linear motor induction plate 3 is located at the lower center of the mounting pipe 1. This central arrangement allows the normal force of the linear motor to dynamically compensate for the suspension systems on both sides, improving both traction efficiency and suspension stability.

[0034] Suspended track 4, such as Figure 4 As shown, two suspended tracks 4 are set on the horizontal surface of the horizontal bearing part and are symmetrically distributed on both sides of the traction track mounting seat 2; each suspended track 4 includes a suspended mounting seat 41 and a metal track 42, the metal track 42 is connected to the horizontal surface of the horizontal bearing part through the suspended mounting seat 41; the metal track 42 is a U-shaped track with the opening of the U-shaped track facing downward.

[0035] Specifically, the suspension track 4 consists of two sets symmetrically distributed on both sides of the traction track mounting base 2. Each set comprises a suspension mounting base 41 and a U-shaped metal track 42. The suspension mounting base 41 is H-shaped. The metal track 42 adopts a U-shaped design with its opening facing downwards, forming a closed magnetic circuit opposite to the hybrid suspension electromagnet on the vehicle. When the electromagnet is energized, a balanced electromagnetic force is generated between the two side walls of the U-shaped metal track 42 and the electromagnet pole surface, achieving stable levitation of the vehicle. The suspension mounting base 41 is detachably connected to the horizontal support unit via clips and bolts, facilitating later maintenance and adjustment.

[0036] It should be noted that the solution proposed in this embodiment is different from the prior art which relies on repulsive force to achieve vehicle levitation. Instead, it relies on installing an electromagnet on the top of the vehicle and making the electromagnet attract the U-shaped metal track 42, thereby enabling the vehicle in the installation pipe 1 to levitate.

[0037] This combined maglev track achieves a synergistic improvement in space optimization and dynamic stability through its structural design. Its core lies in the layout design of a U-shaped suspension track 4 and a centrally located traction rail. The suspension track 4 is symmetrically distributed on both sides of the installation pipe 1, forming a closed magnetic loop with the electromagnets on the vehicle's roof, achieving stable levitation through electromagnetic attraction. Simultaneously, the centrally located linear motor induction plate 3 of the traction rail generates propulsion force and dynamically compensates for the levitation systems on both sides using normal force. This structure significantly improves the utilization rate of the space above the pipe and forms a self-stabilizing mechanism through electromagnetic coupling. When the vehicle deviates laterally, the magnetic attraction on both sides of the U-shaped track automatically adjusts the balance, and the normal compensation of the linear motor effectively suppresses vibration.

[0038] Furthermore, a placement channel 11 is provided within the horizontal support section, parallel to the axis of the installation pipe 1. The cross-sectional shape of the placement channel 11 is preferably rectangular, and its axial extension direction is consistent with the length direction of the installation pipe 1. Specifically, the placement channel 11 is fixed inside the horizontal support section by pre-embedding or integral casting with it. The placement channel 11 is mainly used to accommodate linear facilities such as municipal cables, signal transmission lines, or power supply lines for the maglev system. Its layout design parallel to the pipe axis allows cables to be laid along the entire length of the maglev track without the need for additional trenching. After the cable enters the channel, the pre-reserved guide grooves and fixing clips within the channel ensure orderly cable arrangement and prevent tangling. In addition, the structural integration of the placement channel 11 with the horizontal support section allows cable maintenance only to be performed through the pipe inspection port without damaging the main track structure.

[0039] Furthermore, the traction rail mounting base 2 is provided with a through hole 21 with an elongated cross section. The traction rail mounting base 2 is connected to the linear motor induction plate 3 by multiple bolts. Any bolt passes through the linear motor induction plate 3 and the traction rail mounting base 2 in sequence and enters the through hole 21.

[0040] Specifically, the fastening connection between the traction track mounting base 2 and the linear motor induction plate 3 is achieved through multiple bolts. Each bolt passes sequentially through the corresponding hole on the linear motor induction plate 3, through the body of the traction track mounting base 2, and finally into the space inside the elongated through-hole 21. The design principle is that the linear motor inevitably generates electromagnetic heat during operation, causing the bolts and surrounding metal components to expand. When the bolt head and screw are exposed to the air inside the mounting pipe 1, they can effectively dissipate heat through natural air convection, thereby reducing the overall temperature gradient. This alleviates the localized stress concentration caused by thermal expansion, preventing plastic deformation of the bolts or the traction track mounting base 2 and ensuring the long-term stability of the fastening force. Simultaneously, the elongated through-hole 21 acts as a stress relief groove. Its geometry disperses the peak localized load applied during bolt tightening, allowing the load to be evenly distributed throughout the entire structural area of ​​the traction track mounting base 2. This prevents the formation of micro-stress concentration points at the edge of the mounting base due to high-frequency vibration or dynamic loads (such as the impact of acceleration or braking of a maglev vehicle), thereby inhibiting the initiation and propagation of fatigue cracks.

[0041] For example, in a maglev pipeline transportation system, when the maglev vehicle is running, the electromagnetic coupling between the linear motor induction plate 3 and the onboard mover continuously generates heat. At this time, the bolt passes through the linear motor induction plate 3 and the traction rail mounting base 2 and enters the elongated through-hole 21. The gap in the through-hole 21 allows the bolt to undergo slight displacement during thermal expansion without constraint. At the same time, the natural convection airflow in the air (such as ventilation in the pipeline) carries away the heat from the bolt surface, significantly reducing the accumulation of thermal stress. This mechanism is particularly critical in the high-variable load environment of rail transit. It not only maintains the balanced distribution of bolt tightening force but also improves the overall structural safety of the traction rail mounting base 2.

[0042] Furthermore, the traction rail mounting base 2 is detachably connected to the horizontal bearing part, and the suspension mounting base 41 is detachably connected to both the horizontal bearing part and the metal rail 42.

[0043] Specifically, the traction rail mounting base 2 is fixed to the lower surface of the horizontal support unit via a detachable mechanical connection. This connection is achieved using bolts or other standard fasteners, ensuring a tight fit between the bottom surface of the mounting base and the horizontal plane of the horizontal support unit. This design ensures that the traction rail mounting base 2 can be independently disassembled or replaced without damaging the main structure. Meanwhile, the suspension mounting base 41 employs a dual detachable connection architecture: firstly, it connects to the horizontal plane of the horizontal support unit via bolts or snap-locking mechanisms; secondly, it achieves physical coupling with the base of the metal rail 42 via modular interfaces (such as dovetail grooves or locating pins with bolts). This dual connection mechanism allows the metal rail 42 to be separated independently without disturbing the reference plane of the horizontal support unit.

[0044] During maintenance, operators can directly disassemble faulty sections of the track (such as worn metal track 42 or linear motor induction plate 3) through the pipe inspection port without damaging the structural integrity of the installation pipe 1 and the horizontal load-bearing component. For example, when the linear motor induction plate 3 needs to be replaced due to electromagnetic overheating, the entire traction unit assembly can be disassembled simply by loosening the fastening bolts of the traction track mounting seat 2. For the suspension system, the independent disassembly feature of the metal track 42 allows for the individual replacement of the U-shaped rail or adjustment of the suspension gap without interfering with the traction track. This improves the convenience and economy of maintenance.

[0045] In this embodiment, an integrated horizontal support unit within the installation pipe 1 provides a precise installation reference. Two symmetrically distributed suspension tracks 4 each consist of a suspension mounting base 41 and a downward-opening U-shaped metal track 42. The U-shaped metal track 42 forms a closed magnetic loop with the electromagnet on the vehicle roof, achieving stable levitation. The traction track mounting base 2 is fixed to the lower surface of the horizontal support unit and connected to a centrally located linear motor induction plate 3. The linear motor induction plate 3 electromagnetically couples with the vehicle's moving part to generate propulsion force, while its normal force dynamically compensates for the suspension systems on both sides to enhance stability. The horizontal support unit has a built-in placement channel 11 parallel to the pipe axis to accommodate cables, facilitating continuous cable laying. The elongated through-hole 21 of the traction track mounting base 2 allows bolts to pass through the linear motor induction plate 3 and the mounting base into the through-hole 21 space, utilizing air convection for heat dissipation and dispersing thermal expansion stress, suppressing vibration and fatigue cracks. All components, including the traction track mounting base 2, suspension mounting base 41, and metal track 42, are detachably connected and fixed, facilitating independent maintenance. This design simplifies the construction process and improves space utilization and suspension traction efficiency.

[0046] Example 2

[0047] Based on the same inventive concept, this invention provides an application method for a combined maglev track suitable for pipeline transportation, comprising multiple combined maglev tracks for pipeline transportation connected end to end as in Example 1, wherein any combined maglev track suitable for pipeline transportation is set underground.

[0048] Specifically, each combined maglev track unit suitable for pipeline transportation is based on the design of Embodiment 1, including core components such as the mounting pipe 1, horizontal bearing section, traction track mounting base 2, linear motor induction plate 3, and symmetrically distributed suspension tracks 4. When multiple units are connected end-to-end, their interfaces are precisely aligned through a predefined mechanical coupling mechanism (such as bolt groups or snap-locking mechanisms), thus forming a seamless travel channel and a continuous horizontal bearing reference plane. This connection method utilizes the characteristic that the horizontal plane of the horizontal bearing section is parallel to the axis of the mounting pipe 1 in Embodiment 1, ensuring that the horizontal bearing sections of adjacent units maintain spatial consistency after connection, avoiding track gaps or misalignment problems, and providing a stable driving foundation for maglev vehicles. The beneficial effects are that this method significantly improves the continuity of long-distance pipeline transportation, reduces vibration and impact during vehicle operation, and enhances the overall safety of the system by utilizing geological stability through underground deployment. For example, it isolates external interference (such as climate factors or surface traffic) in the underground environment, reducing maintenance frequency and accident risk.

[0049] All track units are installed underground. Specifically, the installation pipe 1 is pre-embedded in the underground engineering structure, with the horizontal bearing component integrally formed into the inner wall of the pipe and fixed to the underground soil or concrete lining. In principle, underground installation relies on the natural barrier effect of the geological environment. The installation pipe 1 acts as a bearing foundation, forming a rigid support with the surrounding soil and rock. Simultaneously, the built-in placement channel 11 of the horizontal bearing component integrates with the underground municipal pipeline network (such as cables or signal lines), enabling the continuous laying of linear facilities. This utilizes the design of the placement channel 11 parallel to the pipe axis in Example 1. After connection, the placement channel 11 automatically extends into a continuous path, facilitating unified cable laying and management. The beneficial effects are that this method significantly simplifies the construction process. For example, it integrates power supply or communication facilities without the need for additional trenching, reducing engineering costs and environmental impact. Furthermore, underground deployment protects the core components of the system (such as the linear motor induction plate 3 and the U-shaped metal track 42) from external damage, improving durability and reliability. Especially in densely populated urban areas, it allows for concealed construction, reducing interference with surface activities.

[0050] Furthermore, each placement channel 11 of the combined maglev track suitable for pipeline transportation is equipped with a vibration sensor, and the method also includes:

[0051] The system continuously monitors the vibration data of the corresponding installed pipe 1 using vibration sensors. When any vibration sensor detects that the vibration amplitude or frequency does not exceed a preset threshold, the system maintains normal operation (i.e., no operation). When the vibration amplitude or frequency exceeds the preset threshold, the location of the vibration sensor is marked as an abnormal location. Subsequently, the system iterates through a certain number of adjacent vibration sensors upstream and downstream of the abnormal location and defines the locations of all sensors that detect vibration amplitude or frequency exceeding the preset threshold as abnormal locations. Finally, all abnormal location information is summarized and reported to the backend terminal for alarm processing.

[0052] Specifically, a real-time, continuous vibration monitoring mechanism is achieved using vibration sensors placed within channel 11. The vibration sensors capture mechanical vibration signals generated by the installed pipeline 1 through sensitive elements, converting the vibration data into analyzable electrical signals. Preset thresholds are set based on normal operating parameters of the maglev system (such as typical vibration levels during vehicle operation) to distinguish between normal vibrations and abnormal events (such as pipeline structural loosening, vehicle derailment impact, or geological changes). When a single sensor detects vibration exceeding the threshold, the system not only marks the point but also extends to upstream and downstream adjacent sensors for secondary verification. This extended traversal mechanism effectively avoids missed detections caused by local interference or sensor false alarms, ensuring accurate identification of abnormal locations. For example, during pipeline transportation, if a section of the pipeline experiences abnormal vibration due to geological subsidence or vehicle impact, the system can quickly capture and verify the problem area layer by layer, thereby accurately locating the source of the fault. The entire process relies on the intelligent processing capabilities of the back-end terminal to achieve automatic data collection, analysis, and alarm functions.

[0053] It should be noted that, in addition to placing vibration sensors, vibration dampers or dampers can also be placed in placement channel 11. When the vibration sensor detects abnormal vibration, the vibration damper immediately activates to absorb energy, while the damper continuously attenuates vibration energy through viscous resistance. In specific implementation, the vibration damper adopts a metal-rubber composite structure with internal honeycomb cavities to absorb high-frequency vibration waves; the damper is placed at the connection point of adjacent track units, using a combination of hydraulic cylinders and shape memory alloys, capable of handling sudden impacts and adapting to underground temperature changes. For example, when traversing geological fault zones, when the sensor detects low-frequency, large-amplitude vibrations caused by rock displacement, the vibration damper disperses pipeline stress through elastic deformation, while the damper cancels vibration transmission through phase adjustment. The combination of these two components attenuates vibration energy, thereby improving the system's vibration reduction capability.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
