Description

Technical Field

[0001] The invention belongs to the field of magnetic levitation rail transportation, and in particular relates to a magnetic levitation track beam. Background Art

[0002] my country's currently developing conventional maglev trains utilize an electromagnetic system installed on the train's suspension frame and tracks to generate an attractive force, keeping the train vertically suspended above the tracks. Electromagnetic force maintains a horizontal gap between the suspension frame and the tracks, and linear motors convert electrical energy directly into propulsion to propel the train forward. Because the magnetic force of the tracks separates the contact surface between the train and the track, reducing friction, maglev trains offer numerous advantages, including high speed, smooth and comfortable operation, quiet operation, and the elimination of harmful exhaust gases. These trains are a key area of ​​development for rail transit.

[0003] However, when a conventional maglev train is running, the high-speed train will generate a large aerodynamic force, especially when two trains meet on two tracks, the large aerodynamic force will have an adverse effect on the track. Summary of the Invention

[0004] In view of this, an embodiment of the present invention provides a magnetic levitation track beam to solve the technical problem that the large aerodynamic force generated during train operation has an adverse effect on the track.

[0005] To solve the above technical problems, the technical solution of the embodiment of the present invention is implemented as follows:

[0006] An embodiment of the present invention provides a magnetic levitation track beam, which includes:

[0007] More than two main beams are arranged on the upper surface of the base plate and fixedly connected to the base plate. Each main beam is used to form a magnetic levitation track, and every two adjacent main beams and the base plate form a groove-shaped space.

[0008] Furthermore, the ventilation structure is a through hole opened in the vertical direction.

[0009] Furthermore, there are multiple through holes, which are arranged along the extending direction of the bottom plate from the one end to the other end.

[0010] Furthermore, the distances between adjacent through holes are the same.

[0011] Furthermore, the cross-section of the main beam is T-shaped, including a support portion and an upper flange arranged above the support portion.

[0012] Furthermore, the upper surface of the upper flange forms the track surface of the magnetic levitation track.

[0013] Furthermore, the lower surface of the upper flange is used to install a first functional component to generate induced magnetic force.

[0014] Furthermore, the side surface of the upper flange is a guide surface for installing a second functional component to generate induced magnetic force.

[0015] Furthermore, at least one of a cable channel, a maintenance channel and a rescue channel can be provided in the groove-shaped space.

[0017] The magnetic levitation track beam provided in an embodiment of the present invention includes a base plate and two or more main beams disposed on the upper surface of the base plate. The base plate is provided with a ventilation structure. The ventilation structure on the base plate can guide the high-speed airflow generated above the base plate during train operation through the ventilation structure, thereby reducing the aerodynamic force generated by the high-speed airflow on the base plate and thus reducing the adverse effects of the aerodynamic force on the track.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in the present invention will not be described separately.

[0040] In the following description, the terms "first\second" are only used to distinguish different objects, and do not mean that there is any similarity or connection between the two. It should be understood that the orientation descriptions "above" and "below" are all orientations in normal use. The cross-section of the magnetic levitation track beam refers to the cross-section perpendicular to the longitudinal direction of the magnetic levitation track beam. The longitudinal direction of the magnetic levitation track beam is the direction in which the track has the largest size. The longitudinal direction of the base plate refers to the same direction as the longitudinal direction of the magnetic levitation track beam, and the transverse direction of the base plate refers to the direction in which the base plate connects to the main beam on the cross-section of the magnetic levitation track beam.

[0041] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0042] Embodiments of the present invention provide a magnetic levitation track beam that can be used in the field of magnetic levitation rail transit. The following uses a double-track magnetic levitation train track beam as an example to illustrate the operating principle of a magnetic levitation train. A double-track magnetic levitation train track beam consists of a single track beam forming two tracks. Inductive components installed on the track beam generate an attractive force with functional components installed on the train, achieving levitation and braking of the train. The magnetic levitation operating principle of multi-track magnetic levitation trains is similar.

[0043] like Figure 1 As shown, the magnetic levitation track beam includes a base plate 1 and a main beam 2. In some embodiments, by changing the width of the base plate 1 in the transverse direction between adjacent main beams ( Figure 1 The length of CD shown in FIG), the spacing between adjacent main beams can be changed. In some embodiments, as shown in FIG. Figure 2 As shown, the width of the bottom plate 1 in the transverse direction between adjacent main beams can be changed to meet the needs of different geographical conditions during the operation of the magnetic levitation train.

[0044] like Figure 1 As shown, the base plate 1 is the mounting base for the main beam 2, which is arranged above the base plate 1 and fixedly connected to the base plate 1. The main beam 2 includes multiple main beams, each of which is used to form a magnetic levitation track, and every two adjacent main beams 2 and the base plate 1 form a groove-shaped space 4.

[0045] In some embodiments, as Figure 3 As shown, the main beam 2 includes two main beams, namely a first main beam 21 and a second main beam 22. The first main beam 21 is arranged at one end C of the base plate 1, and the second main beam 22 is arranged at the other end D opposite the base plate 1. The first main beam 21, the second main beam 22 and the base plate 1 enclose a groove-shaped space 4. The magnetic levitation track beam structure adopts a groove-shaped cross-section to connect the first main beam 21 and the second main beam 22 through the base plate 1. In terms of structural rigidity, the groove structure can improve the vertical and lateral bending rigidity of the track beam to reduce the bidirectional displacement of the track beam. In addition, when using the groove-shaped cross-section under sunlight conditions, the upper surfaces of the base plate 1 and the main beam 2 are simultaneously exposed to direct sunlight, and the temperature deformation of the base plate 1 and the main beam 2 is small. In other words, the lateral and vertical temperature differential deformation of the magnetic levitation track beam can be effectively alleviated.

[0046] In some embodiments, as Figure 4 As shown, the main beam 2 includes three main beams, namely the first main beam 21, the second main beam 22 and the third main beam 23. The first main beam 21 is arranged at one end C of the base plate 1, the second main beam 22 is arranged at the other end D opposite to the base plate 1, and the third main beam 23 is arranged on the base plate 1, and in the middle position between the first main beam 21 and the second main beam 22, the first main beam 21, the third main beam 23 and the base plate 1 form a first groove-shaped space 41, and the second main beam 22, the third main beam 23 and the base plate 1 form a second groove-shaped space 42. The magnetic levitation track beam structure adopts three main beams 2 to form a structure of two groove-shaped spaces 4. The groove-shaped structure can not only improve the vertical bending stiffness and lateral bending stiffness of the track beam, reduce the bidirectional displacement of the track beam, but also provide more magnetic levitation trains to run simultaneously.

[0047] In some embodiments, the main beam 2 can be fixed to the base plate 1 by bolts to prevent loosening and avoid potential safety hazards. In some embodiments, the main beam 2 can be a concrete slab. The base plate 1 and the main beam 2 can be integrally formed by casting, or after the base plate 1 is laid, they can be cast on the base plate 1 to form a magnetic levitation track to provide support and running track for the train.

[0048] like Figure 1 As shown, the base plate 1 is provided with a ventilation structure 3. The ventilation structure 3 can specifically take the form of through-holes formed in the base plate 1. During train operation, especially during bidirectional train intersections, the high-speed trains drive the airflow within the trough-shaped spaces 4 between adjacent main beams, generating aerodynamic forces on the base plate 1 below the trough-shaped spaces 4. Through the ventilation structure 3, which originates on the base plate 1, the high-speed airflow flows out of the trough-shaped spaces 4, reducing the aerodynamic forces acting on the surface of the base plate 1 and the main beams 2, thereby reducing the impact of aerodynamic forces on the maglev track.

[0049] Further, such as Figure 3 As shown, the ventilation structure 3 on the base plate 1 is a through hole 31 extending vertically. Specifically, the ventilation structure is a through hole 31 extending from top to bottom through the base plate 1. Because the through hole 31 extends vertically, the airflow in the slot-shaped space 4 flows vertically outward from the slot-shaped space 4. As the airflow passes through the base plate 1, it generates no lateral force, thus preventing lateral impact on the base plate. The high-speed airflow flows outward from the through hole 31, reducing the aerodynamic forces acting on the surface of the base plate 1 and the main beam 2, thereby reducing the impact of aerodynamic forces on the magnetic levitation track.

[0050] In some embodiments, the through hole 31 on the bottom plate 1 can have various shapes. Figure 5As shown, the shape of the through hole 31 can be a cylindrical through hole 311 with a circular cross section. The cylindrical through hole 311 can be formed by stamping or milling, and has the advantages of simple structure and convenient forming. This structure can effectively reduce the influence of aerodynamic force on the magnetic levitation track and ensure that the entire base plate 1 has better rigidity. In some embodiments, as Figure 6 and Figure 7 As shown, the shape of the through hole 31 can be a columnar through hole 312 with a long strip cross section. The length direction of the long strip through hole 312 can be arranged along the longitudinal direction of the base plate 1, and can also be arranged along the transverse direction of the base plate 1. The long strip through hole 312 can be formed by stamping and milling, and has the advantages of simple structure and easy forming.

[0051] Furthermore, there are multiple through holes 31 on the bottom plate 1, which are arranged along the extension direction of the bottom plate 1 from one end to the opposite end. When the speed of the maglev train 8 is faster, the aerodynamic force generated is greater, and the impact of the aerodynamic force on the maglev track is also greater; on the contrary, when the speed of the maglev train 8 is slower, the aerodynamic force generated is smaller, and the impact of the aerodynamic force on the maglev track is also smaller. According to the running speed of the maglev train 8, the size of the aerodynamic force generated is predicted, and then the total area of ​​the through holes opened on the bottom plate 1 can be adjusted accordingly. In some embodiments, such as Figure 5 As shown, according to the length of the base plate 1, multiple cylindrical through holes 311 are provided along the extension direction of the base plate 1 from one end A to the other end B in the longitudinal direction. This structure can increase the total area of ​​the through holes on the base plate 1, effectively reducing the adverse effects of aerodynamic forces on the magnetic levitation track, and has the advantages of simple structure and convenient molding. In some embodiments, multiple through holes can be provided along the extension direction of the base plate 1 in both the longitudinal and transverse directions, such as Figure 8 As shown, according to the width of the base plate 1, two rows of cylindrical through holes 311 are provided along the horizontal bridge direction of the base plate 1 extending from one end C to the other end D. The two rows of cylindrical through holes 311 can greatly increase the ventilation area, allowing more airflow to flow out of the slot-shaped space 4 through the cylindrical through holes 311, which can significantly reduce the adverse effects of aerodynamic forces on the magnetic levitation track. In addition, the remaining unopened portion of the base plate 1 is equivalent to a crossbeam, which can maintain sufficient lateral stiffness and balanced force on the base plate structure.

[0052] Furthermore, if Figure 5As shown, the spacing between adjacent through holes 311 along the bridge direction on the bottom plate 1 is the same. Specifically, multiple through holes 311 are set along the bridge direction of the bottom plate 1 from one end A to the other end B, and the center distance between adjacent through holes 311 is a first spacing L1. If L1 is relatively small, the total area of ​​the through holes opened on the bottom plate 1 will be larger, which is suitable for high-speed sections where the speed of the magnetic levitation train 8 is relatively fast. It can allow more airflow to flow out of the slot space 4 through the through holes 311, thereby reducing the impact of aerodynamic force on the magnetic levitation track. In some embodiments, as Figure 9 As shown, multiple through holes 311 are provided along the longitudinal direction of the base plate 1 from one end A to the other end B. The center distance between adjacent through holes 311 is a second spacing L2. If L2 is relatively large, the total area of ​​through holes provided on the base plate 1 is small, which is suitable for use in low-speed sections where the maglev train 8 has a relatively slow speed. The aerodynamic force generated by the maglev train 8 is small, and the total area of ​​through holes 311 with the second spacing L2 on the base plate 1 is sufficient to overcome the impact of the aerodynamic force on the maglev track. Furthermore, in some embodiments, such as Figure 10 As shown, in the intersection section of the high-speed and low-speed sections of the maglev train 8, the spacings between adjacent through holes in the bottom plate 1 along the bridge are different, namely a first spacing L1 and a second spacing L2.

[0053] In some embodiments, as Figure 11 As shown, the spacing between adjacent cylindrical through-holes 311 along the transverse direction of the base plate 1 is uniform. That is, within the cross section of the same magnetic levitation track beam, multiple cylindrical through-holes 311 are present, and the center-to-center spacing between adjacent cylindrical through-holes 311 along the transverse direction is a third spacing L3, and these spacings are uniform. The remaining unperforated portion of the base plate 1 acts as a crossbeam. This structure ensures sufficient transverse rigidity and balanced loads on the base plate structure.

[0054] In some embodiments, as Figure 2 As shown, there are two main beams 2, i.e., a double-line beam. In this case, the main beam 2 has a T-shaped cross-section, including a support portion 5 and an upper flange 6 disposed above the support portion 5. It should be noted that the T-shaped cross-section of the main beam 2 does not require that the surface of the upper flange 6 be perpendicular to the side surfaces of the support portion 5. Some deformation is permitted, as long as the cross-section can generally display a T-shape; it only requires that the support portion 5 extend in a generally vertical direction, and the upper flange 6 extend in a generally horizontal direction and protrude from both sides of the support portion 5.

[0055] In some embodiments, as Figure 12 As shown, in this cross section, the support portion 5 and the upper flange 6 are both in a straight line structure, and the extension direction of the support portion 5 and the extension direction of the upper flange 6 are arranged perpendicularly. This structure enables the support portion 5 to receive a uniform force from the train, thereby reducing the bidirectional displacement of the track beam. In some embodiments, as Figure 13As shown, in this cross section, the support portion 5 is an arc-shaped arm, and the upper flange 6 is a straight-line structure. The extension direction of the upper flange 6 is arranged parallel to the bottom plate 1, and the support portion 5 is arranged at a certain angle to the bottom plate 1. This structure can increase the volume of the trough space 4, providing sufficient accommodation space for other equipment of the maglev train system. At the same time, it can increase the effective area of ​​the bottom plate 1 exposed to direct sunlight, thereby reducing the temperature deformation of the upper flange 6 and the bottom plate 1, that is, the lateral and vertical temperature difference deformation of the maglev track beam can be effectively alleviated. In some embodiments, the support portion 5 and the upper flange 6 can be connected and fastened by welding. In some embodiments, the support portion 5 and the upper flange 6 can be connected and fastened by prefabricated threads and bolted.

[0056] In some embodiments, as Figure 14 As shown, the support portion 5 provides support for the train, and the upper surface 61 of the upper flange 6 forms the track surface of the maglev track. In some embodiments, the lower surface 62 of the upper flange 6 is used to install the first functional component 7 to generate induced magnetic force. Optionally, the maglev track beam is a track beam for the TR-type conventional maglev train, and the cross-section of the upper flange 6 is a straight rail. The first functional component 7 is arranged on both sides of the lower surface 62 of the upper flange 6, and is matched with the functional component 81 arranged on the bottom of the maglev train 8. When the maglev train 8 is in operation, the first functional component 7 and the functional component 81 on the bottom of the maglev train 8 are energized and excited to generate electromagnetic induction, so that the first functional component 7 and the functional component 81 attract each other, thereby realizing the suspension of the maglev train 8 on the track, and the stable suspension gap between the maglev train 8 and the track is ensured by controlling the excitation current of the first functional component 7 and the functional component 81. In some embodiments, as Figure 15 As shown, the maglev track beam is a track beam for HSST-type maglev trains. The upper flange 6 has an F-shaped cross-section on both sides, and the F-shaped track 9 is fixed to both sides of the upper surface 61 of the upper flange 6. In this cross-section, a linear motor reaction plate 91 is arranged on the upper surface of the F-shaped track 9. The grooved surface serves as a suspension gap detection surface 92, and the lower surfaces of the two protruding arms serve as suspension surfaces 93. The F-shaped track 9 cooperates with the functional assembly 81 under the maglev train 8. When the maglev train 8 is in operation, electromagnetic induction causes the F-shaped track 9 and the functional assembly 81 to attract each other, achieving levitation of the train. The gap detection surface 92 is used to regulate the gap between the guide rail and the vehicle body.

[0057] In some embodiments, as Figure 14As shown, the side surface of the upper flange 6 forms a guide surface 10, on which a second functional component 101 is arranged, roughly parallel to the functional component 82 on the side of the maglev train 8. When the maglev train 8 is in operation, an induced current is generated in the second functional component 101. The magnetic field of the induced current is opposite in direction to the magnetic field of the functional component 82, resulting in a repulsive force between the second functional component 101 and the functional component 82. When the maglev train 8 is operating in the center of the entire guide rail, the repulsive forces on both sides are equal in magnitude and opposite in direction, canceling each other out and resulting in a net force of zero. When the maglev train 8 is not in the center of the track, the repulsive forces on both sides are reasonably non-zero. When the maglev train 8 deviates to the left, the functional assembly 82 on the right side of the maglev train 8 approaches the second functional assembly 101 on the right side of the guide surface 10. The functional assembly 82 on the left side of the maglev train 8 then moves away from the second functional assembly 101 on the right side of the guide surface 9. At this point, the repulsive force on the right side of the maglev train 8 increases, while the repulsive force on the left side of the maglev train 8 decreases. The combined force of these two repulsive forces is directed to the right, forcing the maglev train 8 to move right. The more the maglev train 8 deviates to the left, the greater the combined force of the repulsive forces to the right. The opposite occurs when the train deviates to the right. Therefore, the combined force of the repulsive forces on the left and right sides of the maglev train 8 is zero only when the maglev train 8 is in the exact center of the entire track. This ensures that the train can stably maintain its position at the center of the track at any speed.

[0058] In some embodiments, as Figure 16 As shown, a structure of columns 11 and platforms 12 is provided in the trough-shaped space 4, with the top of the platform 12 serving as a rescue passage, and the bottom of the platform 12 serving as a maintenance passage. The height of the column 11 is substantially the same as that of the support portion 5 of the main beam 2, so that the platform 12 and the upper flange 6 are substantially on the same plane. The columns 11 and the platform 12 can be cast as one piece after the base plate 1 is laid, or the columns 11, the platform 12 and the base plate 1 can be connected by welding or bolting. In some embodiments, a large number of cables can be arranged in the trough-shaped space 4, and by arranging cable supports 13 on both sides of the column 11, a large number of cables can be fixed without the need to set up additional cable supports outside the maglev track beam or to lay cables by digging cable wells underground. Making full use of the trough-shaped space 4 not only solves the problems of rescue and maintenance, but also reduces the engineering cost required for laying cables.

[0059] Furthermore, if Figure 17 As shown, ribs 14 are provided in the grooved space 4 on the bottom plate 1. According to the stress conditions of the main beam 2 and the total area of ​​the ventilation structure 3 opened on the bottom plate 1, the bottom plate 1 and the main beam 2 are connected by the ribs 14, which can improve the structural strength and rigidity of the bottom plate 1 and the main beam 2.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
