Description

Technical Field

[0001] This application relates to the field of cargo transportation technology, and more specifically, to a magnetic levitation tube track system. Background Technology

[0002] The content in this section provides only background information related to this application and may not constitute prior art.

[0003] A magnetic levitation tube-rail system is a high-speed transportation system that combines magnetic levitation technology with the concept of a tube-rail system. This system typically includes the following key elements: magnetic levitation technology, which uses magnetic force to levitate vehicles above the track, eliminating physical contact and friction, resulting in low-noise and high-efficiency operation. Magnetic levitation technology can be divided into two types: electromagnetic levitation and superconducting magnetic levitation; tube-rail system, which, based on magnetic levitation technology, typically operates in a low-pressure or vacuum tube to reduce air resistance and further improve speed and energy efficiency; high-speed operation, as the combination of magnetic levitation and tube-rail allows this system to achieve transportation speeds faster than traditional railways; and it is more energy-efficient and has a smaller environmental impact compared to traditional transportation methods.

[0004] Existing maglev rail systems for cargo transportation levitate vehicles above the track using magnetic force. Goods are placed inside the vehicle, and the system is activated to transport them. However, these technologies have several drawbacks. During operation, the motor acts on the electromagnet, creating an attractive force that generates levitation. Simultaneously, the motor generates a force perpendicular to the axis of rotation, often referred to as the normal force. Since the motor and electromagnet are located on opposite sides of the track, the direction of the motor's normal force is opposite to the direction of the levitation force, affecting the stability of the levitation system and increasing energy consumption. Summary of the Invention

[0005] To address the aforementioned technical problems, the purpose of this application is to provide a magnetic levitation rail system that can improve the stability of the levitation system while reducing the energy consumption of levitation transportation.

[0032] 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.

[0033] The following is for reference Figures 1 to 9 This application will be described in further detail.

[0034] Reference Figure 1 A magnetic levitation pipeline system includes a pipeline 1 with a loading port 11 on one side. A sealing plate 12 is rotatably mounted on the pipeline 1 and is rotatably connected to the pipeline 1 via a hinge shaft. The sealing plate 12 is used to close the loading port 11. As one embodiment of this application, a sealing element (not shown in the figure) is provided on the sealing plate 12. By rotating the sealing plate 12, the loading port 11 can be closed. Subsequently, the gap between the sealing plate 12 and the loading port 11 can be closed by the sealing element, so as to ensure that the pipeline 1 can maintain a low pressure or vacuum state for a long time during the transportation of goods, thereby effectively reducing the resistance of transportation, improving the efficiency of transportation and reducing consumption.

[0035] Reference Figure 1 , 2A first steel rail 13 is installed inside the pipe 1, and the first steel rail 13 is located above the pipe 1. A suspension frame 14 is installed below the first steel rail 13 and is slidably connected to the first steel rail 13. A hanging assembly 2 is installed below the suspension frame 14 and is used to suspend the transport vehicle body 19. A linear motor 15 is installed above the suspension frame 14 and an electromagnet 16 is installed above the suspension frame 14. There are two electromagnets 16, which are symmetrically arranged on both sides of the linear motor 15 and are electrically connected to the linear motor 15. An induction plate 17 is fixedly installed below the first steel rail 13 and is located above the linear motor 15. The induction plate 17 is adapted to the linear motor 15.

[0036] Reference Figure 8 and Figure 9 ,like Figure 8 As shown in the figure, the distribution of electromagnet 16 and linear motor 15 in the prior art is illustrated. F1 represents the magnetic force direction of electromagnet 16, while F2 represents the normal force direction of linear motor 15. The opposite directions of F1 and F2 lead to reduced stability and increased energy consumption during operation of the levitation system. Figure 9 As shown, this is the distribution of the electromagnet 16 and the linear motor 15 in this application. F3 is the magnetic force direction of the electromagnet 16, and F4 is the normal force direction of the linear motor 15. The directions of the forces F3 and F4 are the same, which can effectively improve the stability of the suspension system during operation and reduce the energy consumption of transportation.

[0037] Additionally, as one embodiment of this application, refer to Figure 1 The rail system also includes a loading and unloading device 3, which is used to load and unload the transport vehicle body 19.

[0038] Among them, reference Figure 2 Guide rails 4 are fixedly installed on both sides of the first rail 13. Guide grooves 41 are opened on the guide rails 4. The two ends of the suspension frame 14 are located in the guide grooves 41 and are slidably connected to the guide grooves 41. Lateral stop blocks 42 are fixedly installed at both ends of the suspension frame 14. The end of the lateral stop block 42 away from the suspension frame 14 is used to slide and connect with the inner wall of the guide groove 41. Anti-sucking block 43 is fixedly installed above the end of the suspension frame 14. Anti-sucking block 43 is used to slide and connect with the inner top wall of the guide groove 41.

[0039] During transportation, when passing through the bends in the pipeline 1, the transverse stop blocks 42 at both ends of the suspension frame 14 abut against the inner wall of the guide groove 41, which can prevent the suspension frame 14 from getting stuck on the guide rail 4 to a certain extent. At the same time, the anti-sucking stop block 43 can also effectively reduce the friction between the suspension frame 14 and the inner top wall of the guide groove 41, further improving the practicality of the suspension system.

[0040] Reference Figure 2 A drop support block 44 is fixedly installed at both ends of the suspension frame 14. After the cargo transportation is completed, the linear motor 15 is turned off. At this time, the electromagnet 16 no longer generates magnetic attraction. The suspension frame 14 moves downward under the action of gravity. At this time, the drop support block 44 abuts against the inner bottom wall of the guide groove 41.

[0041] As one embodiment of this application, the transverse stop block 42, the anti-lock stop block 43, and the drop support block 44 are all friction blocks, and their materials can be set as semi-metallic friction materials, metallic friction materials, or non-metallic friction materials.

[0042] Reference Figure 2 Guide blocks 5 are fixedly installed on both sides above each electromagnet 16, and the top of the guide blocks 5 is fixedly connected to the bottom of the first rail 13. There are four guide blocks 5 in total, and the four guide blocks 5 are arranged in pairs. Each pair of guide blocks 5 is adapted to one electromagnet 16, and a guide groove 51 is formed between the two guide blocks 5 in the same pair. The width of the guide groove 51 is adapted to the electromagnet 16.

[0043] By setting guide block 5 on the first rail 13, and the guide block 5 being compatible with electromagnet 16, a guiding force is applied to the vehicle body during the use of the suspension system. When the vehicle body deviates laterally, it can be pulled back to the central balance position. At the same time, it can also prevent the vehicle body from swaying too much during high-speed transportation, thus improving the overall reliability of the device in actual use.

[0044] Additionally, refer to Figure 2 A second steel rail 18 is installed below the pipeline 1. After the linear motor 15 is turned off, the transport vehicle 19 is supported by the second steel rail 18 under its own weight, thus preventing the transport vehicle 19 from directly contacting the inner wall of the pipeline 1.

[0045] Reference Figure 2 , 3 The suspension assembly 2 includes a suspension frame 21 and a fixing block 22. The suspension frame 21 includes a horizontal part 211 and a vertical part 212. The top of the horizontal part 211 is fixedly connected to the bottom of the suspension frame 14. The vertical part 212 is fixedly installed at one end of the horizontal part 211 in a vertical direction. A support plate 23 is fixedly provided at the bottom of the vertical part 212 in a horizontal direction. The fixing block 22 is slidably provided on the support plate 23. A connecting frame is fixedly provided on the top of the transport vehicle body 19. An installation block 24 is fixedly provided at the end of the connecting frame. The bottom of the installation block 24 is used to abut against the top of the support plate 23.

[0046] Reference Figure 3A drive assembly 25 is provided on the support plate 23. The drive assembly 25 is used to drive the fixed block 22 to move on the support plate 23. The side wall of the fixed block 22 near the hanger 21 is used to abut against the side wall of the mounting block 24. Figure 3 As shown, a groove 231 is provided on the support plate 23 along the horizontal direction, and a slider 232 is slidably disposed in the groove 231. The slider 232 is connected to the fixed block 22. The drive assembly 25 includes a drive shaft 26 and a drive screw 27. The drive screw 27 is rotatably disposed in the groove 231 along the length direction of the groove 231. The drive shaft 26 is rotatably disposed on the support plate 23. The drive shaft 26 and the drive screw 27 are coaxially fixedly connected. The slider 232 is threadedly sleeved on the drive screw 27.

[0047] As one embodiment of this application, refer to Figure 3 In another embodiment of this application, the slide groove 231 is formed as a T-shaped groove, and the slider 232 is set as a T-shaped block adapted to the slide groove 231. Alternatively, the slide groove 231 can be formed as a dovetail groove, and the slider 232 can be set as a dovetail block adapted to the slide groove 231.

[0048] Additionally, refer to Figure 4 A strip groove 28 is provided on the top of the slider 232 along the length of the slide groove 231. A strip block 29 is slidably arranged in the strip groove 28. The top of the strip block 29 is fixedly connected to the bottom of the fixed block 22. An elastic element 281 is provided in the strip groove 28. The elastic element 281 is used to drive the strip block 29 to move toward the hanging frame 21.

[0049] As one embodiment of this application, refer to Figure 4 The strip groove 28 is formed as a T-shaped groove, and the strip block 29 is set as a T-shaped block adapted to the strip groove 28; as another possible implementation of this application, the strip groove 28 may also be set as a dovetail groove, and the strip block 29 may be set as a dovetail block adapted to the strip groove 28.

[0050] As one embodiment of this application, refer to Figure 4 The elastic element 281 is configured as a compression spring, with one end of the elastic element 281 abutting against the inner wall of the strip groove 28 and the other end abutting against the side wall of the strip block 29.

[0051] In actual use, when the transport vehicle body 19 needs to be hoisted, the connecting frame is first moved to place the mounting block 24 on top of the support plate 23. Then, the drive shaft 26 is rotated to drive the drive screw 27 to rotate. As the drive screw 27 rotates, the slider 232 moves in the slide groove 231. The slider 232 moves the fixed block 22 toward the mounting block 24 and makes the side wall of the fixed block 22 abut against the mounting block 24. After the side wall of the fixed block 22 abuts against the side wall of the mounting block 24, the drive shaft 26 is continuously rotated to continue moving the slider 232 in the slide groove 231. At this time, the elastic element 281 is compressed in the strip groove 28 by the slider 232 and the strip block 29, generating elastic potential energy, which is finally applied to the fixed block 22 through the strip block 29, so that the fixed block 22 has a tendency to move toward the mounting block 24, thereby effectively improving the limiting effect of the mounting block 24 on the support plate 23.

[0052] Additionally, as one embodiment of this application, refer to Figure 3 A knob 261 is coaxially fixed at the end of the drive shaft 26. The diameter of the knob 261 is larger than the diameter of the drive shaft 26. Anti-slip stripes 262 are provided on the peripheral wall of the knob 261. The screw can be driven to rotate by rotating the knob 261, which further facilitates the operation of the staff.

[0053] Reference Figure 5 , Figure 6 and Figure 7 As one embodiment of this application, the loading and unloading device 3 includes a base plate 31, vertical rods 32, and support rods 33. The base plate 31 is disposed on one side of the loading port 11. Two vertical rods 32 are disposed, and the two vertical rods 32 are respectively fixedly disposed on the top of the base plate 31 in the vertical direction. A lifting block 6 is slidably disposed on each vertical rod 32 in the vertical direction. The lifting block 6 is connected to the support rod 33. A bearing block 34 is fixedly disposed on the support rod 33. A support block 35 is fixedly disposed on the side wall of the transport vehicle body 19. The bottom of the support block 35 is used to abut against the top of the bearing block 34. A advancing component 8 is disposed on the support rod 33. The advancing component 8 is used to drive the support rod 33 to move toward the pipe 1. A lifting component 7 is disposed on the vertical rod 32. The lifting component 7 is used to drive the lifting block 6 to move on the vertical rod 32.

[0054] Reference Figure 6 and Figure 7 As one embodiment of this application, the progressive assembly 8 includes a progressive motor 81 and a progressive screw 82. A first through groove 83 is provided on the support rod 33 in the horizontal direction. The progressive screw 82 is rotatably disposed in the first through groove 83. The progressive motor 81 is fixedly disposed on the support rod 33. The output shaft of the progressive screw 82 is coaxially fixedly connected to the progressive screw 82. A connecting block 84 is fixedly disposed on the lifting block 6. The connecting block 84 is threadedly sleeved on the progressive screw 82.

[0055] In actual use, when the advance motor 81 is started, it drives the advance screw 82 to rotate. Since the connecting block 84 is threaded onto the advance screw 82 and is fixedly connected to the lifting block 6, and the lifting block 6 cannot move horizontally, the connecting block 84 also cannot move horizontally. Furthermore, as... Figure 6 As shown, the side wall of the support rod 33 abuts against the side wall of the vertical rod 32, so the support rod 33 cannot rotate in the axial direction of the lead screw 82. In summary, as the lead screw 82 rotates, it can drive the support rod 33 to move in the horizontal direction, thereby sending the transport vehicle body 19 into the pipeline 1.

[0056] Reference Figure 6 The lifting assembly 7 includes a lifting motor 71 and a lifting screw 72. The lifting motor 71 is fixedly mounted on the vertical rod 32. A second through groove 73 is provided on the vertical rod 32 along the vertical direction. The lifting block 6 is slidably mounted in the second through groove 73. The lifting screw 72 is rotatably mounted in the second through groove 73. The lifting block 6 is threaded onto the lifting screw 72. The output shaft of the lifting motor 71 is connected to the lifting screw 72 in a transmission connection.

[0057] As one embodiment of this application, refer to Figure 5 Self-locking casters 9 are fixedly installed at the four corners of the bottom of the base plate 31.

[0058] By setting up self-locking casters 9, it is possible to facilitate the movement of the base plate 31 by the staff, which further facilitates the handling and loading / unloading of the transport vehicle body 19 and the goods inside the transport vehicle body 19.

[0059] The implementation principle of the magnetic levitation tube track system proposed in this application is as follows:

[0060] First, the goods to be transported are placed inside the transport vehicle body 19. Then, the transport vehicle body 19 is placed on the base plate 31, and the base plate 31 is moved to the loading port 11 on the pipeline 1. The position of the base plate 31 is locked by the self-locking casters 9. Then, the lifting assembly 7 is activated, which ultimately moves the support rod 33 upward. The bearing block 34 on the support rod 33 abuts against the support block 35, thereby supporting and lifting the transport vehicle body 19. Then, the advancing assembly 8 is activated, which moves the support rod 33 towards the pipeline 1, and then moves the transport vehicle body 19 towards the pipeline 1. Finally, the transport vehicle body 19 is hoisted by the hanging assembly 2. After the installation of the transport vehicle body 19 is completed, the sealing plate 12 is closed, so that the pipeline 1 is in a low-pressure or vacuum state. Then, the linear motor 15 is turned on, and the linear motor 15 activates the electromagnet 16. The electromagnet 16 generates attraction, which in turn moves the suspension frame 14 upward, generating a driving force along the length of the pipeline 1. Then, the magnetic levitation pipeline rail transport of the goods can be realized.
