Abstract
Description
Technical Field
[0001] This application relates to the field of maglev train technology, and more specifically, to a high-speed maglev suspension magnetic pole. Furthermore, this application also relates to a maglev train including the aforementioned high-speed maglev suspension magnetic pole. Background Technology
[0002] High-speed maglev trains can reach speeds of up to 600 kilometers per hour, filling the gap in travel speed between air and high-speed rail passenger transport. This has significant technical and economic implications for improving my country's three-dimensional high-speed passenger transport network. In particular, the magnetic poles of high-speed maglev vehicles are the core components of the high-speed maglev transportation system. Researching the core components of high-speed maglev vehicles is crucial for improving the performance of maglev vehicles.
[0003] Currently, the common structure of high-speed maglev suspension poles is to assemble the silicon steel core and the flange, then wrap the entire circumference of the core with insulating paper, and then wrap the core with insulating paper with aluminum foil winding. In other words, the aluminum foil winding is separated from the silicon steel core by the insulating paper. Finally, epoxy resin is poured on the outside of the aluminum foil winding.
[0004] However, the high-speed maglev suspension poles inevitably generate heat during operation. Since the thermal barrier coefficients of resin and metal materials such as silicon steel are not the same, the different thermal expansion and contraction deformations make it easier for micro-cracks to appear at the junction of epoxy resin and iron core, and at the junction of epoxy resin and flange. Once water mist passes through the cracks and enters the interior of the pole, it will cause poor insulation of the high-speed maglev suspension poles.
[0005] In summary, how to reduce the possibility of insulation failure in the levitation magnetic poles of high-speed maglev trains is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] In view of this, the purpose of this application is to provide a high-speed maglev suspension pole that has a low probability of insulation failure.
[0007] Another objective of this application is to provide a maglev train including the aforementioned high-speed maglev suspension magnetic poles.
[0008] To achieve the above objectives, this application provides the following technical solution:
[0009] A high-speed magnetic levitation suspension pole includes: an iron core, a flange, a filler block, and an epoxy resin layer;
[0010] The iron core and the flange are fixedly connected to form an integral structure, and the epoxy resin layer covers part of the surface of the integral structure;
[0011] The iron core has a first notch, the flange has a second notch, the flange covers the opening of the first notch located on the opposite surface of the iron core and the flange to form a first waterproof groove, and the epoxy resin layer covers the opening of the second notch located on the surface of the flange away from the iron core to form a second waterproof groove.
[0012] The filler block is a waterproof structure. The filler block fills the first waterproof groove and the second waterproof groove. The epoxy resin layer and the filler block together wrap the integral structure to form a waterproof layer, so as to seal the integral structure inside.
[0013] Furthermore, the coefficient of thermal expansion of the filler block is greater than that of the iron core, the flange, and the epoxy resin layer, so that it can fill the gaps at the junction of the epoxy resin layer and the iron core, and the gaps at the junction of the epoxy resin layer and the flange, when the high-speed magnetic levitation suspension pole is heated.
[0014] Preferably, the surface of the iron core is coated with waterproof adhesive.
[0015] Preferably, the filling block is a silicone block.
[0016] Preferably, the width of the first waterproof groove is 2mm.
[0017] Preferably, the first notch is a through slot extending along the width direction of the iron core near the apex of the flange;
[0018] The second notch is a through slot extending along the width direction of the flange at the apex position of the flange away from the iron core, and the extension direction of the first notch is parallel to the extension direction of the second notch.
[0019] Preferably, there are two flanges, one flange is installed at one end of the iron core along its own length direction, and the other flange is installed at the other end of the iron core along its own length direction. The two flanges and the iron core surround each other to form a corresponding first waterproof groove.
[0020] Preferably, both flanges have the second notch.
[0021] Preferably, the first end of the flange is disposed opposite to the first end of the iron core, and the second end of the flange protrudes from the second end of the iron core;
[0022] The first notch is located at the second end of the iron core, and the second end of the flange and the second end of the iron core form the first waterproof groove.
[0023] Preferably, both the first end of the iron core and the first end of the flange have positioning grooves.
[0024] A maglev train, comprising the high-speed maglev suspension magnetic poles described in any of the above claims.
[0025] In this application, a flange is installed at the transverse end of the iron core by means of bonding or threaded connection to form the above-mentioned integral structure.
[0026] The end of the iron core near the flange has a stepped structure. Specifically, the structure at the center of the iron core protrudes upward from the structure at the end of the iron core near the flange. The groove at the end of the iron core near the flange, which is concave downward compared to the structure at the center of the iron core, is the first notch. The flange protrudes upward from the end of the iron core near the flange. The flange blocks and seals the opening of the first notch on the side near the flange, forming a first waterproof groove with an opening only on the upper surface of the iron core.
[0027] Similarly, the flange has a stepped structure. Specifically, the structure on the side of the flange closer to the iron core protrudes from the structure on the side of the flange farther from the iron core. The groove on the side of the flange farther from the iron core, which is concave downwards compared to the structure on the side of the flange closer to the iron core, is the second notch.
[0028] Correspondingly, an epoxy resin layer is coated on the surface of the above-mentioned integral structure, and the epoxy resin shields the side of the second notch away from the iron core to form a second waterproof groove.
[0029] After casting, filler blocks are embedded in the first and second waterproof grooves to obtain a complete high-speed maglev suspension pole. An epoxy resin layer covers the other surfaces of the integrated structure except for the first and second waterproof grooves, and also covers the exposed surfaces of the filler blocks. This allows the epoxy resin layer and the filler blocks to jointly encapsulate the surface of the integrated structure, thus protecting it. The beneficial effect is that, since the coefficient of thermal expansion of the filler blocks is greater than that of the iron core, flange, and epoxy resin layer, the filler blocks can be made of latex or thermoplastic polyurethane, etc. When the high-speed maglev suspension pole is heated, the filler blocks will expand to fill the cracks at the junction of the epoxy resin and the iron core, and the cracks at the junction of the epoxy resin and the flange, preventing water mist from entering the interior of the pole and reducing the possibility of poor insulation in the high-speed maglev suspension pole.

[0037] 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0038] The core of this application is to provide a high-speed maglev suspension pole with a low probability of insulation failure. Another core aspect of this application is to provide a maglev train comprising the aforementioned high-speed maglev suspension pole.
[0039] This application provides a high-speed maglev suspension pole, including an iron core 1, a flange 2, a filler block, and an epoxy resin layer 3. The iron core 1 and flange 2 are fixedly connected to form an integral structure, and the epoxy resin layer 3 covers a portion of the surface of the integral structure. The iron core 1 has a first notch, and the flange 2 has a second notch. The flange 2 covers the opening of the first notch located on the opposite surface of the iron core 1 and flange 2 to form a first waterproof groove 4. The epoxy resin layer 3 covers the opening of the second notch located on the surface of the flange 2 away from the iron core 1 to form a second waterproof groove 5. The filler block is a waterproof structure, filling the first waterproof groove 4 and the second waterproof groove 5. The epoxy resin layer 3 and the filler block together wrap the integral structure to form a waterproof layer, sealing the integral structure internally. Furthermore, the coefficient of thermal expansion of the filler block is greater than that of the iron core 1, flange 2, and epoxy resin layer 3, enabling it to fill the gaps at the junction of the epoxy resin layer 3 and the iron core 1, and the gaps at the junction of the epoxy resin layer 3 and the flange 2 when the high-speed maglev suspension pole is heated.
[0040] like Figures 1 to 3 As shown, a flange 2 is installed at the transverse end of the iron core 1 by means of bonding or threaded connection to form the above-mentioned integral structure.
[0041] The end of the iron core 1 near the flange 2 has a stepped structure. Specifically, the structure at the center of the iron core 1 protrudes upward from the structure at the end of the iron core 1 near the flange 2. The groove at the end of the iron core 1 near the flange 2, which is concave downward compared to the structure at the center of the iron core 1, is the first notch. The flange 2 protrudes upward from the end of the iron core 1 near the flange 2. The flange 2 blocks and seals the opening of the first notch on the side near the flange 2, forming a first waterproof groove 4 with an opening only on the upper surface of the iron core 1.
[0042] Similarly, flange 2 has a stepped structure. Specifically, the structure on the side of flange 2 closest to the iron core 1 protrudes from the structure on the side of flange 2 furthest from the iron core 1. The groove on the side of flange 2 furthest from the iron core 1 that is recessed downwards compared to the structure on the side of flange 2 closest to the iron core 1 is the second notch.
[0043] Correspondingly, an epoxy resin layer 3 is coated on the surface of the above-mentioned integral structure, and the epoxy resin shields the side of the second notch away from the iron core 1 to form a second waterproof groove 5.
[0044] It should be noted that the number of flanges 2 and the first waterproof groove 4 is not limited. For example, in some specific embodiments, flanges 2 are installed on both the left and right ends of the iron core 1, and the left flange 2 and the left end of the iron core 1 form a first waterproof groove 4; in other specific embodiments, flanges 2 are installed only on the left end of the iron core 1, and the left flange 2 and the left end of the iron core 1 form a first waterproof groove 4.
[0045] After casting, filler blocks are embedded in the first waterproof groove 4 and the second waterproof groove 5 to obtain complete high-speed magnetic levitation levitation poles. Epoxy resin layer 3 covers the other surfaces of the integrated structure except for the first and second waterproof grooves 4 and 5, and also covers the exposed surfaces of the filler blocks. This allows the epoxy resin layer 3 and the filler blocks to jointly encapsulate the surface of the integrated structure, thus protecting it. The beneficial effect is that... Figure 1 As shown, since the coefficient of thermal expansion of the filler block is greater than that of the iron core 1, flange 2 and epoxy resin layer 3, the filler block can be made of latex or thermoplastic polyurethane, etc. After the high-speed maglev suspension pole is heated, the filler block will expand to fill the cracks at the junction of epoxy resin and iron core 1 and the cracks at the junction of epoxy resin and flange 2, so that water mist cannot enter the interior of the pole, thereby reducing the possibility of poor insulation of the high-speed maglev suspension pole.
[0046] Based on the above embodiments, the surface of the iron core 1 is coated with waterproof adhesive to cooperate with the filler block to achieve double protection, improve the effect of preventing water mist from entering the interior of the magnetic pole, and further avoid the phenomenon of poor insulation of the high-speed magnetic levitation levitation pole.
[0047] Based on the above embodiments, the filler block is a silicone block, which reduces the possibility of poor insulation of the high-speed maglev suspension pole, improves wear resistance, and extends the service life of the high-speed maglev suspension pole.
[0048] To ensure that the first waterproof groove 4 and the second waterproof groove 5 remain after pouring for the corresponding filler block to be installed, it is often necessary to install the waterproof groove fixture 6 in the first waterproof groove 4 and the second waterproof groove 5 before pouring. After pouring, the waterproof groove fixture 6 is removed from the corresponding waterproof groove by using a release agent. To avoid the release agent affecting the connection strength between the filler block and the corresponding waterproof groove, based on the above embodiment, the inner surfaces of the first waterproof groove 4 and the second waterproof groove 5 are coated with a reinforcing connection layer, such as an anhydrous alcohol layer.
[0049] Based on the above embodiment, the width of the first waterproof groove 4 is 2mm to ensure the waterproof effect.
[0050] Based on the above embodiment, the first notch is a through groove extending along the width direction of the iron core 1 near the top corner of the flange 2; the second notch is a through groove extending along the width direction of the flange 2 away from the top corner of the iron core 1, and the extension direction of the first notch is parallel to the extension direction of the second notch, so as to ensure the waterproof effect of the high-speed magnetic levitation suspension pole along its own thickness direction.
[0051] Based on the above embodiment, there are two flanges 2. One flange 2 is installed at one end of the iron core 1 along its own length direction, and the other flange 2 is installed at the other end of the iron core 1 along its own length direction. The two flanges 2 and the iron core 1 form a corresponding first waterproof groove 4.
[0052] like Figures 1 to 3 As shown, flanges 2 are installed on the left and right ends of the iron core 1. At the lower left corner of the iron core 1, a through groove is opened through the iron core 1 in a direction perpendicular to the paper as a first notch. The flange 2 located on the left side of the iron core 1 covers the left opening of the first notch to form a first waterproof groove 4 that opens downward. At the lower right corner of the iron core 1, a through groove is opened through the iron core 1 in a direction perpendicular to the paper as a first notch. The flange 2 located on the right side of the iron core 1 covers the right opening of the first notch to form another first waterproof groove 4 that opens downward.
[0053] Of course, the arrangement of the first waterproof groove 4 is not limited to the example above. For example, some flanges 2 and iron core 1 are used to form the first waterproof groove 4, while the remaining flanges 2 and iron core 1 are not used to form the first waterproof groove 4.
[0054] Based on the above embodiment, both flanges 2 have a second notch.
[0055] like Figures 1 to 3 As shown, at the lower left corner of the left flange 2, a through groove penetrating the iron core 1 in a direction perpendicular to the paper is provided as a second notch. The portion of the epoxy resin layer 3 extending vertically on the left side of the flange 2 covers the left opening of the second notch, thereby forming a second waterproof groove 5 that opens downwards. At the lower right corner of the right flange 2, a through groove penetrating the iron core 1 in a direction perpendicular to the paper is provided as a second notch. The portion of the epoxy resin layer 3 extending vertically on the right side of the flange 2 covers the right opening of the second notch, thereby forming a second waterproof groove 5 that opens downwards.
[0056] Of course, the arrangement of the first waterproof groove 4 is not limited to the example above. For example, some flanges 2 have a second notch, while the remaining flanges 2 and the iron core 1 do not have a second notch.
[0057] Based on the above embodiment, the first end of the flange 2 is disposed opposite to the first end of the iron core 1, and the second end of the flange 2 protrudes from the second end of the iron core 1; the first notch is located at the second end of the iron core 1, and the second end of the flange 2 and the second end of the iron core 1 surround to form a first waterproof groove 4.
[0058] like Figures 1 to 3 As shown, the upper end of the flange 2 is recessed downwards into the iron core 1, or the upper end of the flange 2 is flush with the upper end of the iron core 1, in which case the upper end of the flange 2 is positioned opposite to the upper end of the iron core 1; conversely, the lower end of the flange 2 protrudes downwards from the lower end of the iron core 1, so as to block the side opening of the first notch opened at the lower left corner and / or lower right corner of the iron core 1, forming a first waterproof groove 4 with an opening at the lower end.
[0059] Based on the above embodiment, both the first end of the iron core 1 and the first end of the flange 2 have positioning grooves 7.
[0060] like Figure 2 As shown, a positioning groove 7 extending laterally is provided at the upper end of the iron core 1 and the upper end of the flange 2 to facilitate the winding of the winding on the outer periphery of the above-mentioned integral structure.
[0061] Based on the above embodiments, a waterproof groove fixture 6 is also included, such as... Figure 4As shown, the waterproof groove tooling 6 can be inserted into or removed from the corresponding first waterproof groove 4 or second waterproof groove 5 to fill the corresponding first waterproof groove 4 or second waterproof groove 5, so as to prevent epoxy resin from being poured into the first waterproof groove 4 and second waterproof groove 5.
[0062] In use, before casting, the waterproof groove fixture 6 is manufactured and placed into the first waterproof groove 4 and the second waterproof groove 5. Then, the above-mentioned integral structure with the waterproof groove fixture 6 is cast to form an epoxy resin layer 3. Then, the waterproof groove fixture 6 is removed to make room for the internal space of the corresponding first waterproof groove 4 and the second waterproof groove 5. Then, the corresponding filler block is embedded into the first waterproof groove 4 and the second waterproof groove 5.
[0063] In addition to the high-speed maglev suspension poles mentioned above, this application also provides a maglev train that includes the high-speed maglev suspension poles disclosed in the above embodiments. The structure of other parts of the maglev train can be found in the prior art, and will not be described in detail here.
