Description

Technical Field

[0001] This invention relates to the field of magnetic levitation vehicle technology, and more particularly to a superconducting magnet frame. Background Technology

[0002] The superconducting magnet frame is a key structural component of the suspension system, serving to connect the superconducting magnets on both sides and bear the vehicle's load. However, in existing technologies, the middle section of the suspension system is positioned relatively high, increasing the risk of interference with the vehicle's underframe and hindering the reduction of the floor height of the connecting passageway between the two vehicles. This makes it difficult to ensure that the passageway floor height matches the passenger compartment floor height for convenient passenger passage. Therefore, a new type of suspension system needs to be developed that can lower the height of the middle section, and the superconducting magnet frame is one of the key technologies in this field.

[0003] Therefore, how to develop a superconducting magnet frame that reduces the height of the superconducting magnet frame to lower the height of the middle part of the suspension frame and make room for the vehicle body through passage is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a superconducting magnet frame to reduce the height of the middle position of the suspension frame, thus allowing more space for the through channel. To achieve the above objective, this invention provides the following technical solution:

[0006] There are two first crossbeams. Each first crossbeam includes an upper crossbeam, a lower crossbeam, and a vertical tie rod. The upper crossbeam and the lower crossbeam are connected by the vertical tie rod. The two first crossbeams are respectively disposed at both ends of the superconducting magnet for connecting the superconducting magnets on both sides.

[0007] The second crossbeam is a U-shaped crossbeam. Multiple U-shaped crossbeams are spaced apart on the superconducting magnet and located between the two first crossbeams arranged at both ends of the superconducting magnet. The main body of the U-shaped crossbeam is lower than the height of the upper crossbeam.

[0019] Optionally, in the superconducting magnet frame described above, the number of the second crossbeam and the number of the third crossbeam may be equal or unequal.

[0020] The superconducting magnet frame provided by this invention is used to connect superconducting magnets on both sides, and includes a first crossbeam and a second crossbeam.

[0029] The core of this invention is to provide a superconducting magnet frame to reduce the height of the middle position of the suspension frame, thus making more space for the through channel.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1As shown, an embodiment of the present invention discloses a superconducting magnet frame for connecting superconducting magnets 110 on both sides, including a first crossbeam 120 and a second crossbeam 130.

[0032] It should be noted that the suspension frame is the running gear of the magnetic levitation vehicle. The superconducting magnet 110 is a magnet made of superconducting material, providing levitation and traction for the vehicle. Each suspension frame contains two superconducting magnets 110. The superconducting magnet frame connects the superconducting magnets 110 on both sides. The upper part of the superconducting magnet frame is the main structural frame, which is the main load-bearing component of the suspension frame and provides the mounting base for other equipment. Therefore, the height of the suspension frame mainly depends on the height of the superconducting magnet frame.

[0033] There are two first crossbeams 120. Each first crossbeam 120 includes an upper crossbeam 121, a lower crossbeam 122, and a vertical tie rod 123. The upper crossbeam 121 and the lower crossbeam 122 are connected by the vertical tie rod 123. Specifically, the number of vertical tie rods 123 can be two or one; the specific number is not limited here, as long as it can improve the stability of the upper crossbeam 121 and the lower crossbeam 122. The two first crossbeams 120 are respectively set at both ends of the two superconducting magnets 110 to connect the superconducting magnets 110 on both sides. It should be noted that the material of each component in the first crossbeam 120 can be stainless steel or aluminum alloy; the specific type is not limited here.

[0034] The second crossbeam 130 is a U-shaped crossbeam. Multiple U-shaped crossbeams are spaced apart on the superconducting magnet 110 and located between the two first crossbeams 120 arranged at both ends of the superconducting magnet 110. At the same time, the main body 131 of the U-shaped crossbeam is lower than the height of the upper crossbeam 121. The arrangement of the U-shaped crossbeams reduces the spatial height of the mounting frame, thereby reducing the height of the middle position of the suspension frame, which can make room for more space in the vehicle body passage and facilitate pedestrian passage.

[0035] The superconducting magnet frame provided by this invention is used to connect superconducting magnets 110 on both sides, and includes a first crossbeam 120 and a second crossbeam 130. There are two first crossbeams 120, each including an upper crossbeam 121 and a lower crossbeam 122. A vertical tie rod 123 is provided between the upper crossbeam 121 and the lower crossbeam 122. The two first crossbeams 120 are respectively located at both ends of the superconducting magnet. The second crossbeam 130 is a U-shaped crossbeam, with multiple U-shaped crossbeams spaced apart on the superconducting magnet 110 and located between the two first crossbeams 120. The main body of the U-shaped crossbeam is lower than the height of the upper crossbeam 121.

[0036] The superconducting magnet frame provided by the present invention has a second crossbeam 130 that reduces the height of the superconducting magnet frame, thereby reducing the height of the middle position of the suspension frame and making more space for the through channel; at the same time, the superconducting magnet 110 is connected by the first crossbeam 120 and the second crossbeam 130, ensuring the overall stability of the superconducting magnet frame.

[0037] like Figure 1 and Figure 2 As shown, in a specific embodiment of the present invention, a third crossbeam 140 is also included. The third crossbeam 140 is arranged parallel to the first crossbeam 120 and the second crossbeam 130. Specifically, the installation position and number of the third crossbeam 140 can be set as needed and can be flexibly adjusted. The third crossbeam 140 may be omitted if necessary. The first crossbeam 120, the second crossbeam 130, the third crossbeam 140, and the superconducting magnet 110 form an upward-opening space for mounting the frame. The third crossbeam 140 increases the stability of the connection between the superconducting magnets 110 on both sides.

[0038] like Figure 3 As shown, in a specific embodiment of the present invention, the second crossbeam 130 includes a main body 131 and a connecting part 132. The main body 131 is arranged parallel to the first crossbeam 120, and the connecting part 132 is located at both ends of the main body 131, forming an upwardly convex structure, meaning the connecting part 132 extends upwards from the main body 131 and is connected to it. Specifically, the main body 131 and the connecting part 132 can be an integral structure or a separate structure, and can be connected later by welding or other methods. The specific connection method is not limited here, as long as the connection is secure. The connecting part 132 is used to connect the superconducting magnets 110 on both sides, and the connection point is located in the middle of the superconducting magnets 110. The connection part 132 provides sufficient space for the mounting frame on the upper part of the second crossbeam 130, reducing the overall height of the superconducting magnet frame, thereby reducing the overall height of the suspension frame and providing more space for pedestrian passageways. The connection point between the connecting part 132 and the superconducting magnet 110 is located in the middle of the superconducting magnet 110 and cooperates with the first crossbeam 120 to make the connection of the superconducting magnet 110 more stable.

[0039] like Figure 1 and Figure 2As shown, to prevent the superconducting magnet 110 from undergoing rhomboid deformation, based on the above embodiment, the connecting part 132 is connected to the superconducting magnet 110 via a first rubber node 210 and a longitudinal tie rod 220. The first rubber node 210 is a flexible connection point, meaning the second crossbeam 130 is connected to the superconducting magnet 110 via a flexible connection point, reducing disturbances during high-speed vehicle operation. To prevent the superconducting magnet 110 from undergoing rhomboid deformation, a longitudinal tie rod 220 is provided on the connecting part 132. The longitudinal tie rod 220 extends in the same direction as the superconducting magnet 110, with one end connected to the connecting part 132 and the other end connected to the superconducting magnet 110. It should be noted that longitudinal tie rods 220 are provided at both ends of the second crossbeam 130 where they connect to the superconducting magnet 110. Due to perspective limitations, only the longitudinal tie rod 220 at one end of the second crossbeam 130 is shown in the figure; the other end is not shown. The longitudinal tie rods 220 prevent the superconducting magnets 110 from undergoing rhomboid deformation. This means the superconducting magnets 110 on both sides will not misalign in the extending direction, i.e., the vehicle's running direction, thus improving the stability and safety of the superconducting magnet connection. Simultaneously, it reduces the height of the middle section of the superconducting magnet 110, saving space. Those skilled in the art will understand that the number and installation position of the longitudinal tie rods 220 can be adjusted as needed.

[0040] In a specific embodiment of the present invention, the first rubber node 210 and the connecting part 132 are in an interference fit manner. The connecting part 132 has a mounting hole for interference fit with the first rubber node 210. The interference fit method has a simple structure and a tight connection. The first rubber node 210 is connected to the superconducting magnet 110 through a connector, thereby realizing the hinged connection between the second crossbeam 130 and the superconducting magnet 110. A longitudinal tie rod 220 is provided between the second crossbeam 130 and the superconducting magnet 110. One end of the longitudinal tie rod 220 is connected to the connecting part 132, and the other end is connected to the superconducting magnet 110. The second crossbeam 130 is connected to the longitudinal tie rod 220 through the first rubber node 210, which effectively avoids the superconducting magnet 110 from rhomboid deformation.

[0041] like Figure 1 and Figure 2As shown, in order to achieve a flexible connection between the longitudinal tie rod 220, the second crossbeam 130, and the superconducting magnet 110, in a specific embodiment of the present invention, second rubber nodes 230 are provided at both ends of the longitudinal tie rod 220. The second rubber nodes 230 are interference-fitted with the longitudinal tie rod 220, and mounting holes for interference-fitting with the second rubber nodes 230 are provided on the longitudinal tie rod 220. The second rubber nodes 230 are connected to the connecting part 132 and the superconducting magnet 110. Specifically, the connection between the second rubber nodes 230 and the connecting part 132 can be achieved by cooperating with the mounting seat provided on the connecting part 132. The second rubber nodes 230 and the superconducting magnet 110 are connected by fasteners, thereby achieving a flexible connection between the longitudinal tie rod 220, the second crossbeam 130, and the superconducting magnet 110.

[0042] like Figure 3 As shown, in a specific embodiment of the present invention, the two ends of the upper crossbeam 121 are connected to the superconducting magnet 110 via a third rubber node, the two ends of the lower crossbeam 122 are connected to the superconducting magnet 110 via a fourth rubber node, and the two ends of the vertical tie rod 123 are connected to the upper crossbeam 121 and the lower crossbeam 122 via a fifth rubber node, respectively. The upper crossbeam 121 and the lower crossbeam 122 are connected by the vertical tie rod 123, forming a parallelogram structure. When the vehicle passes through a curve, the superconducting magnet frame can undergo a certain deformation to adapt to the requirements of the superelevation of the track.

[0043] It should be noted that, in order to improve the stability between the upper crossbeam 121 and the lower crossbeam 122, in a specific embodiment of the present invention, a vertical tie rod 123 is provided between the upper crossbeam 121 and the lower crossbeam 122, and a fifth rubber node is provided at both ends of the vertical tie rod 123. Specifically, the fifth rubber node is interference-fitted with the vertical tie rod 123, and the vertical tie rod 123 is provided with mounting holes that are interference-fitted with the fifth rubber node. The fifth rubber node at the upper end of the vertical tie rod 123 is connected to the upper crossbeam 121, and the fifth rubber node at the lower end of the vertical tie rod 123 is connected to the lower crossbeam 122.

[0044] Based on the above embodiment, both the upper crossbeam 121 and the lower crossbeam 122 are equipped with tie rod seats 240. The fifth rubber nodes located at both ends of the vertical tie rod 123 are connected to the tie rod seats 240, thereby realizing the connection between the vertical tie rod 123 and the upper crossbeam 121 and the lower crossbeam 122. Specifically, the connection between the tie rod seats 240 and the upper crossbeam 121 and the lower crossbeam 122 can be achieved by bolt fastening or by welding.

[0045] To improve the stability of the superconducting magnet frame, in a specific embodiment of the present invention, a transverse tie rod 250 is provided on the upper crossbeam 121. One end of the transverse tie rod 250 is located on the upper crossbeam 121 and inside the upper crossbeam 121, that is, the transverse tie rod 250 faces the interior of the space enclosed by the two superconducting magnets 110. The other end of the transverse tie rod 250 is connected to the frame. During vehicle operation, the frame constrains the upper crossbeam 121 through the transverse tie rod 250, preventing the superconducting magnet from tilting and further improving the stability of the superconducting magnet frame.

[0046] like Figure 1 and Figure 2 As shown, in a specific embodiment of the present invention, the number of third crossbeams 140 is equal to the number of second crossbeams 130. It should be noted that the number of third crossbeams 140 may not be equal to the number of second crossbeams 130. The number and installation position of the third crossbeams 140 can be flexibly adjusted according to the actual situation.
