Description

Technical Field

[0001] This disclosure relates to the field of high-speed maglev rail transit technology, and in particular to an installation and construction method suitable for a long stator of a conventional high-speed maglev train. Background Technology

[0002] With the maturity of high-speed maglev rail transit technology, more and more cities are starting to invest in the construction of maglev rail transit industry. Using long stator cores is one of the technical means to realize high-speed maglev technology, and it is also a relatively mature technology at present. However, the process of installing functional components and long stator cores on track beams is very complicated. Both functional components and long stator cores need to be installed by hoisting, which is not only difficult to operate and inefficient, but also has certain dangers. Summary of the Invention

[0003] To address the aforementioned technical issues, this disclosure provides an installation and construction method suitable for conventional high-speed magnetic levitation long stators.

[0004] This disclosure provides an installation and construction method suitable for conventional high-speed magnetic levitation long stators, including the following steps:

[0005] S1. Install the functional component with the connecting surface facing upwards on the mounting platform;

[0006] S2. Install the long stator core onto the connecting surface of the functional component;

[0007] S3. Flip the installation platform to rotate the long stator core to below the functional components;

[0008] S4. Transport the functional components and the long stator core together to the installation station and install them on the track beam;

[0009] S5. Arrange the three sets of coil cables on the long stator core.

[0010] Optionally, S1 specifically involves first rotating the mounting plate in the mounting platform and rotating its top plane to a horizontal position, then locking the mounting plate and mounting bracket, and then installing the functional component with its connecting surface facing upwards on the top plane of the mounting plate.

[0011] Optionally, S3 specifically involves unlocking the mounting plate from the mounting bracket and rotating the mounting plate 180 degrees, causing the long stator core mounted above the functional component to rotate to below the functional component.

[0012] Optionally, S4 specifically involves driving the transport trolley to move below the long stator core, removing the functional component from the mounting plate, and fixing the long stator core and the functional component together to the transport trolley. Then, the transport trolley is used to transport the functional component and the long stator core to the installation position of the track beam, and finally, the functional component and the long stator core are installed at the installation position of the track beam.

[0013] Optionally, the drive transport trolley carries the functional component and the long stator core to one side below the track beam. The translation mechanism on the transport trolley pushes the functional component and the long stator core in a direction perpendicular to the extension of the functional component to the installation position directly below the track beam. Then, the lifting mechanism on the transport trolley lifts the functional component and the long stator core to the installation position. Finally, the functional component and the long stator core are removed from the transport trolley and installed at the installation position on the track beam.

[0014] Optionally, S5 specifically involves bending all three sets of coil cables into an S-shape using a bending device, and then arranging the first coil cable, the second coil cable, and the third coil cable alternately in pairs in the groove at the bottom of the long stator core along the extension direction of the functional component.

[0015] Optionally, the extension direction of the wire trough is perpendicular to the extension direction of the functional component. The functional part of the coil cable is located inside the wire trough, and the connecting part of the coil cable extends to the outside of the wire trough and is used to connect two adjacent functional parts belonging to the same coil cable. The connecting parts of the same coil cable are staggered on both sides of the functional component along the extension direction of the functional component to form an S-shaped coil cable.

[0016] Optionally, in S5, after bending the three sets of coil cables into an S-shape, the coil cables are shaped, and the two adjacent functional sections are adjusted to a parallel position by a shaping device, and the edge of the connecting part is adjusted to a position perpendicular to the wire groove.

[0017] Optionally, the coil cable is passed sequentially through the wire feeding device, bending device and shaping device by the conveying device, and then conveyed to the bottom of the long stator core, so that the connection parts of the three sets of coil cables can correspond one by one with the wire grooves at the bottom of the long stator core.

[0018] Optionally, the first coil cable is first pressed into the corresponding wire groove, and then the second coil cable is pressed into the corresponding wire groove. At this time, the connection part of the first coil cable is squeezed upward by the connection part of the second coil cable and undergoes adaptive deformation. Finally, the third coil cable is pressed into the corresponding wire groove, so that the connection part of the second coil cable is squeezed upward by the connection part of the third coil cable and undergoes adaptive deformation.

[0019] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0020] The installation method for long stators of conventional high-speed magnetic levitation provided in this disclosure involves first mounting the connecting surfaces of functional components upwards on an installation platform with a flipping function. This not only facilitates the installation of the long stator core onto the connecting surfaces of the functional components, significantly improving the installation efficiency of the long stator core and functional components, but also ensures the connection effect between the long stator core and functional components, improving the reliability of the connection between the long stator core and functional components. Furthermore, this installation process, which places the functional components on the installation platform and then places the long stator core on the functional components, is more reliable and safe, preventing the long stator core from suddenly detaching from the functional components and injuring operators or damaging the long stator core. After the long stator core is installed onto the functional components, it can simply be flipped using the installation platform and placed on a transport trolley, making the operation simple and safe.

[0042] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0043] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0044] With the maturity of high-speed maglev rail transit technology, more and more cities are starting to invest in the construction of maglev rail transit industry. Using long stator cores is one of the technical means to realize high-speed maglev technology, and it is also a relatively mature technology at present. However, the process of installing functional components and long stator cores on track beams is very complicated. Both functional components and long stator cores need to be installed by hoisting, which is not only difficult to operate and inefficient, but also has certain dangers.

[0045] Based on this, this embodiment provides an installation method suitable for conventional high-speed magnetic levitation long stators. By first mounting the connecting surfaces of the functional components upwards on an installation platform with a flipping function, it not only facilitates the installation of the long stator core onto the connecting surfaces of the functional components, significantly improving the installation efficiency of the long stator core and functional components, but also ensures the connection effect between the long stator core and functional components, improving the reliability of the long stator core's connection to the functional components. Furthermore, this installation process, which places the functional components on the installation platform and then places the long stator core on the functional components, is more reliable and safer, preventing the long stator core from suddenly detaching from the functional components and thus injuring operators or damaging the long stator core. After the long stator core is installed onto the functional components, it can simply be flipped using the installation platform and placed on a transport trolley; the operation is simple and safe. The following detailed embodiments illustrate this method:

[0046] Reference Figures 1 to 18 As shown in the figure, the installation and construction method for a conventional high-speed magnetic levitation long stator provided in this embodiment includes the following steps:

[0047] S1. Install the functional component 1 with the connecting surface 11 facing upwards on the mounting platform 51;

[0048] S2. Install the long stator core 2 on the connecting surface 11 of the functional component 1;

[0049] S3. Flip the mounting platform 51 to rotate the long stator core 2 to below the functional component 1;

[0050] S4. Transport the functional component 1 and the long stator core 2 together to the installation station and install them on the track beam 3;

[0051] S5. Arrange the three sets of coil cables on the long stator core 2.

[0052] By first installing the connecting surface 11 of the functional component 1 upwards on the installation platform 51 with a flipping function, it is not only easier to install the long stator core 2 onto the connecting surface 11 of the functional component 1, significantly improving the installation efficiency of the long stator core 2 and the functional component 1, but also ensures the connection effect between the long stator core 2 and the functional component 1, improving the reliability of the long stator core 2 connected to the functional component 1. Furthermore, this installation process of placing the functional component 1 on the installation platform 51 and then placing the long stator core 2 on the functional component 1 is more reliable and safe, preventing the long stator core 2 from suddenly detaching from the functional component 1, thereby injuring the operator or damaging the long stator core 2. After installing the long stator core 2 onto the functional component 1, it is only necessary to flip the installation platform 51 and place it on the transport trolley 52, which is simple to operate and safe to use.

[0053] Continue to refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, S1 specifically involves first rotating the mounting plate 511 in the mounting platform 51 and rotating its top plane to a horizontal position. Then, the mounting plate 511 and the mounting frame 512 are locked. Then, the connecting surface 11 of the functional component 1 is mounted on the top plane of the mounting plate 511 with the connecting surface 11 facing upward. The mounting plate 511 can be connected to the mounting frame 512 through a rotating shaft. The rotating shaft is equipped with a locking mechanism. The mounting plate 511 can also be connected to the mounting frame 512 through a structure such as a robotic arm. As long as the mounting plate 511 can drive the functional component 1 and the long stator core 2 to achieve a stable flipping action, and can also make the functional component 1 and the long stator core 2 place stably on the mounting plate 511, it is acceptable.

[0054] In some embodiments, S3 specifically involves unlocking the mounting plate 511 from the mounting bracket 512 and rotating the mounting plate 511 180 degrees so that the long stator core 2 mounted above the functional component 1 rotates to below the functional component 1.

[0055] Continue to refer to Figures 1 to 8As shown, S4 specifically involves driving the transport trolley 52 to move below the long stator core 2, removing the functional component 1 from the mounting plate 511, and fixing the long stator core 2 and the functional component 1 together to the transport trolley 52. ​​Then, the transport trolley 52 is used to transport the functional component 1 and the long stator core 2 to the installation position of the track beam 3. Finally, the functional component 1 and the long stator core 2 are installed at the installation position of the track beam 3. It should be understood that the transport trolley 52 is equipped with a transport platform 521. After the installation platform 51 flips the functional component 1 and the long stator core 2, the functional component 1 and the long stator core 2 are first stabilized on the transport platform 521, and then the functional component 1 is removed from the installation platform 51.

[0056] In some embodiments, the drive trolley 52 carries the functional component 1 and the long stator core 2 to one side below the track beam 3. The translation mechanism on the trolley 52 pushes the functional component 1 and the long stator core 2 in a direction perpendicular to the extension of the functional component 1 to directly below the installation position on the track beam 3. Then, the lifting mechanism on the trolley 52 lifts the functional component 1 and the long stator core 2 to the installation position. Next, the functional component 1 and the long stator core 2 are removed from the trolley 52 and installed at the installation position on the track beam 3. It should be noted that the transport platform 521 is connected to the chassis of the transport trolley 52 through the translation mechanism and the lifting mechanism. The transport platform 521 is moved to directly below the installation position on the track beam 3 through the coordinated operation of the translation mechanism and the lifting mechanism.

[0057] Continue to refer to Figures 9 to 18 As shown, S5 specifically involves bending all three sets of coil cables into an S-shape using a bending device, and then arranging the first coil cable 41, the second coil cable 42, and the third coil cable 43 alternately in pairs within the slots 21 at the bottom of the long stator core 2 along the extension direction of the functional component 1. It should be understood that the coil cables in two slots 21 separated by two slots are the same coil cable. That is, if one slot 21 is randomly selected as the first slot and the fourth slot 21 along the extension direction of the functional component 1 is the fourth slot, the coil cables in the first slot and the fourth slot are the same coil cable.

[0058] In a further embodiment, the extension direction of the wire groove 21 is perpendicular to the extension direction of the functional component 1. The functional part of the coil cable is located inside the wire groove 21, and the connecting part of the coil cable extends to the outside of the wire groove 21 and is used to connect two adjacent functional parts belonging to the same coil cable. The connecting parts of the same coil cable are staggered on both sides of the functional component 1 along the extension direction of the functional component 1 to form an S-shaped coil cable. This arrangement enables the coil cable to be arranged more neatly on the long stator core 2, and also ensures that the functional parts of the three sets of coil cables are stably in the best working state, thus improving the reliability of operation.

[0059] In some embodiments, in S5, after bending the three sets of coil cables into an S-shape, the coil cables are shaped. A shaping device adjusts adjacent functional sections to parallel positions and adjusts the edge of the connecting section to a position perpendicular to the wire groove 21. This shaping further ensures that the coil cables are installed on the long stator core 2 according to a set posture, improving the neatness, aesthetics, and reliability of the coil cables. The shaping process includes first positioning and clamping the coil cables to maintain their posture during transport on the conveyor. Then, the connecting section and functional sections are moved and adjusted in three directions: the transport direction along the conveyor belt plane, the direction perpendicular to the transport direction, and the height direction perpendicular to the conveyor belt plane. This completes the shaping process. When the shaped coil cables are pressed onto the long stator core 2, the posture of the coil cables is maintained, thereby more effectively reducing surface wear and ensuring the insulation performance of the coil cables.

[0060] In a further embodiment, the coil cable passes sequentially through the wire feeding device, bending device, and shaping device via a conveying device, and is conveyed to the bottom of the long stator core 2, so that the connection parts of the three sets of coil cables can correspond one-to-one with the wire grooves 21 at the bottom of the long stator core 2; that is, after the coil cable is fed out from the coil cable rack, it can be in a continuous conveying state, and the bending device and shaping device can work simultaneously to realize the continuous conveying of the coil cable and improve work efficiency.

[0061] In some embodiments, the first coil cable 41 is first pressed into the corresponding groove 21, and then the second coil cable 42 is pressed into the corresponding groove 21. At this time, the connecting part of the first coil cable 41 is pressed upward by the connecting part of the second coil cable 42 and undergoes adaptive deformation. Finally, the third coil cable 43 is pressed into the corresponding groove 21, so that the connecting part of the second coil cable 42 is pressed upward by the connecting part of the third coil cable 43 and undergoes adaptive deformation. It should be understood that the diameter of the groove 21 matches the diameter of the coil cable. The groove 21 and the coil cable can be an interference fit or a clearance fit, as long as it is ensured that the coil cable will not be exposed from the groove 21 after being pressed into it. It should be noted that the opening of the wire trough 21 is provided with a protruding structure that engages with the coil cable. The protruding structure allows the coil cable to be more stably fixed in the wire trough 21. The adaptive deformation of the connection part of the first coil cable 41 and the connection part of the second coil cable 42 can ensure the flatness of the bottom of the long stator core 2 after the three sets of coil cables are installed, improving the aesthetics and not affecting other operations.
