Description

Technical Field

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

[0002] The superconducting magnet frame is a key component of the superconducting suspension system, serving to connect the superconducting magnets on both sides and bear the vehicle's load, transmitting guiding force, levitation force, traction force, and braking force to the vehicle. Because the levitation force generated by the superconducting magnets and the vehicle's vertical load do not act in a straight line, a rollover problem can occur with the superconducting magnets.

[0003] Therefore, how to design a superconducting magnet frame to solve the problem of superconducting magnet roll caused by the levitation force and the vertical load of the vehicle not acting in a straight line 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 the present invention is to provide a superconducting magnet frame to solve the problem of superconducting magnet roll caused by the levitation force and the vertical load of the vehicle not acting in a straight line.

[0005] Another object of the present invention is to provide a suspension frame.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A superconducting magnet frame for connecting superconducting magnets on both sides, comprising:

[0008] A crossbeam is spaced between the superconducting magnets on both sides;

[0009] The two ends of the crossbeam are connected to the superconducting magnet via tie rods. The tie rods at both ends of the crossbeam are arranged in parallel, and the extension direction of the tie rods is perpendicular to the extension direction of the superconducting magnet. The two ends of the tie rods are connected to the crossbeam and the superconducting magnet via flexible nodes.

[0010] Optionally, in the superconducting magnet frame described above, the number of tie rods at any end of the crossbeam is at least two, and the tie rods are arranged in parallel.

[0011] Optionally, in the above-mentioned superconducting magnet frame, the crossbeam is an upward-opening U-shaped crossbeam, the U-shaped crossbeam includes a main body and a side wall, the main body of the crossbeam is arranged parallel to the tie rod, and the height of the main body of the crossbeam is lower than the height of the side wall;

[0012] Two tie rods are provided at either end of the crossbeam, wherein at least one tie rod is provided at the top of the side wall and at least one tie rod is provided at the bottom of the side wall.

[0013] Optionally, in the superconducting magnet frame described above, the tie rods located at both ends of the crossbeams are arranged symmetrically along the center line connecting the centers of each crossbeam.

[0014] Optionally, in the superconducting magnet frame described above, one end of the tie rod is connected to the crossbeam via a first rubber node, and the other end is connected to the superconducting magnet via a second rubber node.

[0015] Optionally, in the superconducting magnet frame described above, a plurality of primary suspension devices are provided on the superconducting magnet.

These tie rods are arranged parallel to each other at both ends of the crossbeam, and their ends are connected to the crossbeam and the superconducting magnet via flexible joints. This allows the superconducting magnet to move vertically on both sides, enabling the superconducting magnet frame to deform to adapt to changes in the elevation of the track, while preventing the superconducting magnet from rolling.

[0026] The core of this invention is to provide a superconducting magnet frame to solve the problem of superconducting magnet roll caused by the levitation force and the vertical load of the vehicle not acting in a straight line.

[0027] Another core aspect of this invention is providing a suspension frame.

[0028] 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.

[0029] like Figure 1 As shown, an embodiment of the present invention discloses a superconducting magnet frame for connecting superconducting magnets 110 on both sides, including a crossbeam 120 and a tie rod 130.

[0030] It should be noted that the suspension frame is the running gear of a maglev vehicle, similar to the bogie of a rail vehicle. The superconducting magnet frame is the main load-bearing component of the suspension frame. The superconducting magnet 110 is a magnet made of superconducting material, providing levitation and traction for the vehicle. Each superconducting magnet 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 structure, 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.

[0031] A crossbeam 120 is spaced between the superconducting magnets 110 on both sides, connecting them. Both ends of the crossbeam 120 are connected to the superconducting magnets 110 via tie rods 130. The tie rods 130 at both ends of the crossbeam 120 are arranged parallel to each other, with their extension direction perpendicular to that of the superconducting magnets 110. Both ends of the tie rods 130 are connected to the crossbeam 120 and the superconducting magnets 110 via flexible nodes. The connection between the tie rods 130 and the flexible nodes allows the superconducting magnets 110 on both sides to move vertically. The superconducting magnet frame can deform to accommodate changes in the track's elevation and prevent the superconducting magnets 110 from rolling sideways. It should be noted that the materials of the components in the crossbeam 120 can be stainless steel or aluminum alloy; the specific type is not limited here. The spacing between two adjacent crossbeams 120 may be the same or different. The installation position and number of crossbeams 120 can be set as needed and can be flexibly adjusted.

[0032] The superconducting magnet frame disclosed in this invention has a crossbeam 120 whose two ends are connected to a superconducting magnet 110 via tie rods 130. The tie rods 130, located at both ends of the crossbeam 120, are arranged in parallel. The two ends of the tie rods are connected to the crossbeam 120 and the superconducting magnet 110 via flexible nodes, allowing vertical movement. The superconducting magnet frame can deform to adapt to changes in the elevation of the track, while preventing the superconducting magnet 110 from rolling. The superconducting magnet frame disclosed in this invention has a simple structure, is easy to install, has a low failure rate, and the stress state of the tie rods 130 and the crossbeam 120 is relatively simple, ensuring the stability and safety of the structure.

[0033] The superconducting magnet frame disclosed in this embodiment of the invention has at least two tie rods 130 at any end of the crossbeam 120, and the tie rods 130 are arranged in parallel. Figure 1 and Figure 2 The following explanation uses two 130-type pull rods as an example.

[0034] It should be noted that because some of the suspension frames are located in the connecting area between the two carriages, and components such as the workshop passageway, articulation devices, and traction beams are installed in this area, the car body underframe occupies a lot of space. This makes it difficult to lower the floor height of the workshop passageway to match the floor height of the passenger compartment, causing inconvenience for passengers.

[0035] like Figure 2As shown, in order to provide more space for the vehicle's passageway and facilitate passenger passage, in a specific embodiment of the present invention, the crossbeam 120 is an upward-opening U-shaped crossbeam. The U-shaped crossbeam includes a main body and side walls. The main body of the crossbeam is arranged parallel to the tie rod 130, and the height of the main body is lower than the height of the side walls. The upper part of the superconducting magnet frame is the framework. The U-shaped crossbeam reduces the height of the mounting space for the framework, thereby reducing the height of the middle position of the suspension frame, which can provide more space for the vehicle's passageway and facilitate passenger passage.

[0036] For the tie rod 130 located at either end of the crossbeam 120, at least one tie rod 130 is located at the top of the side wall to connect the top of the crossbeam 120 to the top of the superconducting magnet 110; at least one tie rod 130 is located at the bottom of the side wall to connect the bottom of the crossbeam 120 to the bottom of the superconducting magnet 110. This arrangement ensures the firmness of the connection between the superconducting magnets 110 on both sides and the crossbeam 120.

[0037] like Figure 1 As shown, in order to ensure the force balance of the superconducting magnets 110 on both sides, in a specific embodiment of the present invention, the tie rods 130 set at both ends of the crossbeam 120 are symmetrically arranged along the center line connecting each crossbeam 120. The symmetrical arrangement can make the superconducting magnets 110 on both sides balanced.

[0038] like Figure 2 As shown, in order to allow each end of the superconducting magnet 110 to move freely in the vertical direction independently, in a specific embodiment of the present invention, one end of the pull rod 130 is connected to the crossbeam 120 via a first rubber node 140, and the other end is connected to the superconducting magnet 110 via a second rubber node 150. Specifically, the first rubber node 140 and the second rubber node 150 are flexibly connected, allowing each end of the superconducting magnet 110 to move freely in the vertical direction independently. The first rubber node 140 and the second rubber node 150 have the same structure, which is a commonly used flexible connection method, and its specific structure will not be described in detail here.

[0039] To buffer and absorb vibrations and impacts from the superconducting magnet 110 and the track, the superconducting magnet frame disclosed in this embodiment of the invention includes multiple primary suspension devices 160 on the superconducting magnet 110. Specifically, the multiple primary suspension devices 160 are spaced apart between the crossbeams 120, and the primary suspension devices 160 on the two superconducting magnets 110 are arranged symmetrically. The specific number and installation position of the primary suspension devices 160 are determined according to the position of the installed frame and can be flexibly adjusted.

[0040] Based on the above embodiments, the primary suspension device 160 is mounted on the superconducting magnet 110 via a support base. The support base is fixedly connected to the superconducting magnet 110. Specifically, the connection between the support base and the superconducting magnet 110 can be welding or fixing via fasteners, as long as the primary suspension device 160 is securely installed. The primary suspension device 160 can be a rubber spring or a steel spring; the specific type is not limited.

[0041] This invention also discloses a suspension frame, which includes the superconducting magnet frame disclosed in the above embodiments. Therefore, it has all the technical effects of the superconducting magnet frame, and will not be repeated here.

[0042] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Generally, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
