Description

Magnetic Levitation Space Curved Beam Forming System and Forming Method Technical Field

[0001] This invention belongs to the field of magnetic levitation track technology, specifically relating to a magnetic levitation space curved beam forming system and forming method. Background Technology

[0002] Maglev technology uses magnets to generate lift and thrust, allowing vehicles to levitate very close to the "guide rail". Since there is no physical contact friction, most of the power is used to overcome air resistance. In terms of operating energy consumption, high-speed maglev has a significant advantage over high-speed railways.

[0003] The track beam is the foundation for the operation of high-speed maglev trains, and it is a high-precision component within the maglev track structure system. In high-speed maglev technology, because the levitation height and guide clearance of the high-speed maglev train are only 8-10mm, the precision requirements for the construction and installation quality of the track are extremely high. To ensure this precision, current bridge prefabrication technologies both domestically and internationally require the use of large five-axis triple-controlled boring and milling machines for processing, resulting in very high costs for the track beam.

[0004] Maglev track beams are classified into straight beams, curved beams, and spatial curved beams according to their alignment. In addition to being arc-shaped with a certain radius of curvature on the horizontal plane, spatial curved beams are also arc-shaped in the Z direction. Due to their structural characteristics and the requirements for processing precision, the processing and assembly of spatial curved beams have become very difficult.

[0005] Summary of the Invention

[0006] The purpose of this invention is to provide a magnetic levitation spatial curved beam forming system and forming method to solve the problems existing in the processing of magnetic levitation spatial curved beams.

The vertical drive component is connected to the first connector via a ball joint and is used to drive the first connector to move in the vertical direction. The vertical drive component is mounted on the side mold assembly.

[0015] In some embodiments, the first connector includes a rotating part and a connecting part, the rotating part and the connecting part forming a T-shaped structure. The functional component template is provided with two frame plates arranged side by side, and each frame plate is provided with a sliding hole. The two ends of the rotating part are respectively fitted into the sliding holes of the two frame plates, so that the rotating part can rotate along the axis of the rotating part in the sliding hole and slide along the lateral direction of the functional component template in the sliding hole. The connecting part is fitted between the two frame plates and has a clearance fit between the frame plates.

[0016] In some embodiments, the lateral adjustment assembly includes a lateral adjustment member disposed on the outside of the functional component template;

[0017] The lateral adjustment component includes a lateral drive component and a second connector.

The lateral drive component and the second connector are connected by a ball joint, which drives the second connector to move horizontally along the lateral direction of the functional component template.

[0018] In some embodiments, the functional component templates are arranged side by side in sequence along the longitudinal direction of the side templates, and a locking component for fixing the functional component templates is provided between adjacent functional component templates.

[0019] In some embodiments, the locking component includes a plurality of longitudinal driving members disposed at one end of the functional component template, the driving ends of the longitudinal driving members being able to press against adjacent functional component templates.

[0020] In some embodiments, the functional component positioning assembly includes a steel plate positioning mechanism for positioning an L-shaped steel plate for a magnetic levitation functional component, the steel plate positioning mechanism being used to fix the L-shaped steel plate onto the functional component template.

The L-shaped steel plate is then tightened and fixed on the functional component template using the steel plate fixing parts. The position of the L-shaped steel plate is adjusted using the steel plate adjusting parts.

[0032] In some embodiments, after casting, the connection between the functional component template and the magnetic levitation functional component is removed, the mold is opened, and the formed magnetic levitation spatial curved beam is lifted out.

[0033] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0034] 1) In the forming of spatial curved beams, the present invention positions and installs magnetic levitation functional components on the forming system through functional positioning components, and sets multiple functional component templates in a section of beam.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, but not all embodiments.

[0055] Maglev track beams typically have maglev functional components 40 installed on both sides of the beam surface to ensure the operation of high-speed maglev trains. In the maglev spatial curve beam of this invention, the maglev functional components are integrally formed onto the beam during the beam casting process to ensure the structural strength of the maglev functional components on the spatial curve beam and to ensure the accuracy of the installation position of the maglev functional components on the spatial curve beam.

[0056] The maglev functional components here include several stator sleeves 41 and L-shaped steel plates 42 welded from sliding surface steel plates and guide surface steel plates. The stator sleeves and L-shaped steel plates are independent components with no connection between them. Therefore, when the maglev track beam is cast, the positions of the stator sleeves and L-shaped steel plates need to be accurately positioned to ensure the positional accuracy of the maglev functional components on the maglev track beam.

[0057] For spatial curved beams, the fact that they have a certain curvature in both the horizontal plane and the Z-direction not only makes the forming of spatial curved beams difficult, but also makes the positioning and adjustment of magnetic levitation functional components during the forming process very difficult.

[0058] The positioning and installation of maglev functional components in the forming system is a key step in the manufacturing process of maglev track beams. Its installation deviation directly affects the deviation of the stator surface, guide surface, and sliding surface, and ultimately affects the running comfort of high-speed maglev trains.

[0059] Taking the magnetic levitation space curved beam shown in Figures 1 and 2 as an example, the magnetic levitation space curved beam 10 includes a beam body 11 and supports 12 located at both ends of the beam body. The beam body 11 and supports 12 are integrally cast with concrete. The bottom surface of the beam body is suspended and located above the bottom surface of the supports. The outer contour line of the toe cross section of the supports 12 is set as an arc.

[0060] By setting supports at both ends of the beam and setting the outer contour of the toe cross section of the supports to be arc-shaped, it is convenient to form maglev track beams with different inclination angles on the bottom surface of the supports through a single forming system during the forming of the track beam, thereby meeting the forming requirements of spatial curved beams with different cross slope angles.

[0061] The outer contour of the toe cross-section of beam 11 is arc-shaped to facilitate the integral molding of the magnetic levitation space curved beam and the design of the molding system structure. As shown in Figure 2, the cross-section of beam 11 is π-shaped.

[0062] The magnetic levitation functional components 40 are respectively set on the beam wings on both sides of the magnetic levitation space curved beam. When the magnetic levitation track beam is cast, the magnetic levitation functional components 40 are integrally formed on the beam body 11 and the support 12.

[0063] To address the aforementioned problems and the structure of the maglev spatial curved beam, this invention incorporates a functional component positioning assembly in the maglev spatial curved beam forming system. The structure of this assembly is designed to allow for arbitrary adjustment of the spatial position of the maglev functional components according to the shape of the spatial curved beam, and to position and install the maglev functional components on the forming system. This effectively solves the problems encountered during the overall forming of the maglev spatial curved beam.

[0064] In some embodiments, referring to Figures 3, 4 and 5, a magnetic levitation space curve beam forming system may typically include a bottom mold assembly, a side mold assembly, an end mold assembly and an inner mold assembly.

[0065] The side mold assembly typically includes two side mold plates 241 that are disposed opposite each other on both sides of the bottom mold assembly.

[0066] The forming system is also equipped with a functional component positioning assembly for positioning the magnetic levitation functional components on the forming system. Corresponding to the magnetic levitation functional components set on both sides of the magnetic levitation space curve beam, a set of functional component positioning assemblies is set on each of the two side templates.

[0067] Referring to Figures 5 and 6, the functional component positioning assembly includes multiple functional component templates 31 for positioning the stator sleeves of the maglev functional components. The stator sleeves 41 can be fixedly installed on the functional component templates 31 by bolts. At this time, the setting position of the stator sleeves on the maglev track beam can be adjusted by adjusting the spatial position of the functional component templates.

[0068] Referring to Figures 7, 8, 9, 10, 11, and 12, the functional component template 31 has a positioning part 310 for positioning and installing the stator sleeve of the magnetic levitation functional component. The stator sleeve 41 can be fixedly installed onto the positioning part 310 of the functional component template using bolts. The stator sleeve includes a stator sleeve 411 with dovetail grooves and a stator sleeve 412 without dovetail grooves. Therefore, the positioning part of the functional component template is configured with different positioning structures according to different stator sleeve shapes. Threaded holes for positioning and assembly are provided on the stator sleeve. After the stator sleeve is positioned and installed on the positioning part, it is fixed onto the functional component template by bolts engaging with the threaded holes on the stator sleeve.

[0069] An adjustment mechanism is provided between the side template 241 and the functional component template 31 to adjust the spatial position of the functional component template.

[0070] In some embodiments, the adjustment mechanism includes at least two sets of vertical adjustment components and at least two sets of horizontal adjustment components. Here, the adjustment mechanism is described using the example of setting two sets of vertical adjustment components and two sets of horizontal adjustment components.

[0071] Both sets of vertical adjustment components and two sets of horizontal adjustment components are arranged along the longitudinal direction of the functional component template. For example, the two sets of vertical adjustment components are respectively located near both ends of the functional component template, and the two sets of horizontal adjustment components are also respectively located near both ends of the functional component template. The vertical adjustment components are used to adjust the vertical position of the functional component template at the corresponding position, thereby enabling adjustment of the vertical position of the functional component template and its tilt angle along the longitudinal direction. The horizontal adjustment components are used to adjust the horizontal position of the functional component template at the corresponding position, thereby enabling adjustment of the horizontal position of the functional component template in the molding system and its tilt angle along the horizontal direction. At this time, the spatial position of the functional component template on the molding system can be adjusted through the adjustment mechanism, thereby enabling arbitrary adjustment of the position of the stator sleeve on the magnetic levitation track beam.

[0072] In some embodiments, the vertical adjustment assembly includes at least two vertical adjustment members disposed below the functional component template. Taking the two vertical adjustment members as an example, the two vertical adjustment members are arranged along the horizontal direction of the functional component template. The four vertical adjustment members in the two sets of vertical adjustment assemblies are respectively disposed at the four corners near the functional component template to adjust the spatial position of the functional component template.

[0073] The vertical adjustment component includes a vertical drive component 32 and a first connector 34. The first connector 34 is rotatably and slidably connected to the functional component template 31, allowing the first connector to rotate about its connection point with the functional component template in a vertical plane along the transverse direction of the functional component template, and also to move horizontally along the transverse direction of the functional component template. The vertical drive component and the first connector are connected by a ball joint. The vertical drive component is used to drive the first connector to move in the vertical direction, and is mounted on the side mold assembly.

[0074] The vertical drive component 32 can be an electric push rod arranged in the vertical direction. Based on the connection structure between the first connector and the functional component template, the functional component template is adjusted by four vertical adjustment components. The four vertical drive components drive the first connector to move in the vertical direction, adjusting the functional component template to the set spatial position.

[0075] In some embodiments, the vertical drive member 32 is fixedly mounted on the skeleton beam 246 located on the outer side of the side template end.

[0076] The first connector 34 includes a rotating part 341 and a connecting part 342. The rotating part 341 and the connecting part 342 form a T-shaped structure. For example, the rotating part and the connecting part can be a T-shaped structure composed of two sections of round tubes.

[0077] The functional component template 31 has two frame plates 311 arranged side by side, each with a sliding hole 312. The sliding holes can be, for example, square holes. The rotating part 341 is fitted into the sliding holes of the two frame plates at both ends, allowing it to rotate along its axis and slide laterally within the sliding holes. A connecting part 342 is fitted between the two frame plates with a clearance fit. For example, the width of the sliding hole can be matched to the diameter of the rotating part, enabling it to rotate along its axis and slide along the length of the sliding hole. Additionally, limiting structures can be provided on the rotating part outside the two frame plates to prevent it from deflecting around the axis of the connecting part when sliding along the length of the sliding hole, ensuring the stability of the connection between the first connector and the functional component template.

[0078] By designing the first connector, the vertical adjustment components can move the functional component template to the set position, while avoiding interference between the various vertical adjustment components during the adjustment process. Setting the first connector to slide against the functional component template provides sufficient space for adjustment of the functional component template in the lateral direction.

[0079] In some embodiments, the lateral adjustment assembly includes a lateral adjustment member disposed outside the functional component template.

[0080] The lateral adjustment component includes a lateral drive component 33 and a second connector 35. The second connector 35 is slidably connected to the outer side plate of the functional component template 31, so that the second connector can move vertically on the functional component. The lateral drive component and the second connector are connected by a ball joint, which is used to drive the second connector to move horizontally along the lateral direction of the functional component template, thereby adjusting the position of the functional component template in the lateral direction of the molding system.

[0081] The lateral drive component 33 can be a horizontally arranged lateral electric push rod. The lateral electric push rod is fixedly mounted on the side mold back 247 located outside the side template. The side mold back 247 can move together with the side template. The drive end of the lateral electric push rod is ball-jointed with the second connector. Since the second connector is slidably connected to the functional component template, it can adjust the functional component template in the lateral direction while providing a certain space for the vertical adjustment component to adjust the functional component template in the vertical direction. It can also fix the position of the functional component template in the lateral direction after the adjustment is completed.

[0082] A vertical movable space is provided at the connection position between the lateral adjustment component and the functional component template, allowing the functional component template to move vertically relative to the lateral adjustment component. For example, as shown in Figure 10, a vertical movable groove 313 can be provided on the side of the functional component template, and one end of the second connector 35 extends into the movable groove 315 and forms a sliding fit connection with the movable groove.

[0083] The movable groove is designed to provide vertical adjustment space between the horizontal adjustment component and the functional component template, ensuring that the horizontal adjustment component does not interfere with the vertical adjustment of the functional component template. At the same time, it provides a certain amount of movement space for the demolding of the functional component template during mold opening. During the mold opening operation, the functional component template can be driven to move downward by controlling the vertical adjustment component to achieve demolding of the functional component template, and then the side mold assembly is demolded. This can avoid interference between the functional component template and the magnetic levitation track beam during demolding of the side mold assembly. Referring to Figure 13, the functional component template separates from the magnetic levitation functional component cast on the curved beam during demolding.

[0084] When adjusting the functional component template, the vertical adjustment component and the horizontal adjustment component can be controlled by following the movement. For example, the position of the functional component template can be adjusted by calculating the movement of each vertical and horizontal drive component based on the adjustment position of the functional component template.

[0085] In some embodiments, when forming a beam, the forming system decomposes the spatial curved beam into four segments in the longitudinal direction. Based on the spatial position characteristics of the spatial curved beam, the spatial positions of the four functional component templates can be adjusted respectively. The structural configuration of the spatial curved beam is formed by fitting the four functional component templates. This can ensure the forming accuracy of the spatial curved beam and better meet the casting and forming requirements of spatial curved beams with different spatial curve parameters.

[0086] In some embodiments, the functional component templates 31 are arranged side by side in sequence along the longitudinal direction of the side templates, and locking components for fixing the functional component templates are provided between adjacent functional component templates. In this way, after each functional component template is adjusted into place, the locking components fix the position of the functional component template on the side template to prevent the position of the functional component template from changing during the beam pouring process.

[0087] Specifically, the locking assembly includes multiple longitudinal drive members 39 disposed at one end of the functional component template. For example, one longitudinal drive member 39 can be disposed on each side of one end of the functional component template. The longitudinal drive member can be a longitudinal electric push rod, so that the driving end of the longitudinal drive member can press against the end face of the adjacent functional component template. When two adjacent functional component templates are pressed together in the longitudinal direction by the longitudinal electric push rod, the functional component template can be stably fixed in space based on the action of the vertical adjustment assembly, the horizontal adjustment assembly, and the locking assembly on the functional component template.

[0088] At this point, the gaps formed between adjacent functional component templates can be filled and sealed using adhesive strips or other structures.

[0089] To better accommodate the shape of the maglev components on the maglev track beam and to more effectively position and adjust their location according to the beam's alignment, the maglev components are designed to be composed of multiple segments on a single beam. Taking a standard maglev track beam with a span of 12.384m as an example, the maglev components are divided into four segments. This allows for more flexible adjustment of the positions of the maglev components on the track beam by adjusting the positions of the four segments, thus ensuring better positional accuracy.

[0090] Based on the above-mentioned magnetic levitation functional components, the functional component positioning component in the forming system is set to consist of 4 functional component templates. Each functional component template corresponds to a set of magnetic levitation functional components and is used to independently position a set of magnetic levitation functional components. At this time, the positioning and adjustment of the magnetic levitation functional components on the magnetic levitation track beam can be achieved by adjusting the 4 functional component templates.

[0091] The aforementioned adjustment of the position of the functional component template enables the adjustment and positioning of the stator sleeve set on the functional component template, thereby controlling the accuracy of the stator surface. Based on the realization of the above functions, the functional component positioning assembly also includes a steel plate positioning mechanism for positioning the L-shaped steel plate of the maglev functional component. The steel plate positioning mechanism uses the functional component template as a positioning reference to fix the L-shaped steel plate on the functional component template, thereby adjusting and fixing the position of the L-shaped steel plate in the maglev functional component and ensuring the positional accuracy of the sliding surface and guide surface.

[0092] In some embodiments, referring to FIG6, the steel plate positioning mechanism includes at least two sets of steel plate positioning components disposed on the outside of the functional component template. The steel plate positioning components are distributed along the longitudinal direction of the functional component template. Each steel plate positioning component includes a steel plate fixing member 36 capable of pressing and fixing the L-shaped steel plate onto the functional component template at a corresponding position and a steel plate adjusting member 37 capable of adjusting and supporting the L-shaped steel plate in the lateral direction at a corresponding position. The steel plate fixing member 36 and the steel plate adjusting member 37 are disposed on the side mold assembly. An auxiliary support member 38 for providing support for the L-shaped steel plate is disposed on the side of the functional component template corresponding to the steel plate positioning component.

[0093] The steel plate fixing component 36 and the steel plate adjusting component 37 can be adjusted screws or electric struts installed on the side mold backing 247. Taking the adjusting screw as an example, the adjusting screw is threadedly connected to the side mold backing, and the adjusting screw is horizontally set with one end extending towards the L-shaped steel plate. The steel plate fixing component 36 is located at a position corresponding to the side of the functional component template, while the steel plate adjusting component 37 is located above the steel plate fixing component.

[0094] Referring to Figures 7 and 10, the auxiliary support 38 can be two ear plates set on one side plate of the functional component template, which provide support for the L-shaped steel plate.

[0095] During installation, the L-shaped steel plate is hoisted to the installation position and supported by auxiliary support components. The steel plate fixing components are then adjusted to firmly secure the L-shaped steel plate to the side of the functional component template. The installation position of the L-shaped steel plate is then checked. Based on the check results, the position of the L-shaped steel plate is adjusted using the steel plate adjusting components until it is in the designated position. At this point, the steel plate adjusting components also serve to support the L-shaped steel plate. Through the steel plate fixing components and adjusting components, the L-shaped steel plate can be positioned and adjusted while preventing it from moving during concrete pouring and vibration, thus ensuring the quality of the maglev track beam.

[0096] In some embodiments, the functional component positioning assembly includes a plurality of functional component templates 31, which are arranged sequentially along the longitudinal direction of the side templates, and each functional component template is used to position a group of magnetic levitation functional components.

[0097] In some embodiments, the molding system is also applicable to the casting and molding of magnetic levitation space curved beams with different cross slope angles.

[0098] In this molding system, the bottom mold assembly is set on the base 21, including the beam bottom mold 221 and the support bottom mold 222 located at both ends of the beam bottom mold. The support bottom mold 222 is configured to be able to rotate around the central axis of the upper end face of the base, so that the inclination angle of the support bottom mold can be adjusted to adapt to the molding requirements of maglev track beams with different cross slope angles.

[0099] The side mold assembly includes two side templates 241 arranged opposite each other. The cross-section of the side template at the position corresponding to the toe 13 of the maglev track beam is arc-shaped. Setting the side template at the position corresponding to the toe of the maglev track beam as arc-shaped allows the support bottom mold to be rotated and adjusted to any desired tilt angle, as shown in Figures 4 and 14. It is easy to see that the center of the arc portion on the side template 241 coincides with the rotation center of the support bottom mold, so that the support bottom mold can always form a good fit with the side templates on both sides, ensuring the forming quality of the maglev track beam.

[0100] The end formwork assembly includes two end templates 251 located at both ends of the side formwork assembly and two support end templates 26 located at both ends of the beam bottom formwork for forming the inner end faces of the supports. The two end templates 251 are respectively located at both ends of the side templates 241. When the mold is closed, an end-to-side closing method is adopted. Adhesive strips and shims can be set at the joint position of the end templates and the side templates. The included angle between the end templates and the side templates can be adjusted by adjusting the thickness of the shims.

[0101] The support end formwork 26 and the end formwork 251 are arranged opposite to each other, and are located between the bottom formwork of the beam and the bottom formwork of the support. The support end formwork, the end formwork, and the bottom formwork of the support are used together to form the support part of the maglev track beam.

[0102] The forming system is configured with a beam bottom mold for forming the beam body and a support bottom mold for forming the support. The support bottom mold is configured as a rotatable structure, which can be flexibly adjusted according to the forming requirements of the support bottom surface with different inclination angles, thereby forming maglev track beams with different cross slope angles. At the same time, with the use of arc-shaped side templates, a single forming system can be used to form maglev track beams with different cross slope angles.

[0103] In some embodiments, an inner mold assembly 27 is further included, which is disposed on the bottom mold 221 of the beam. The inner mold assembly is configured according to the π-shaped structure of the beam and is used to form the π-shaped beam during casting.

[0104] In some embodiments, referring to FIG14, the molding system further includes a bottom mold drive 223. The support bottom mold 222 is connected to the base 21 via a rotating shaft, and the bottom mold drive 223 is used to drive the support bottom mold to rotate around the rotating shaft. The bottom mold drive 223 includes two electric push rods respectively disposed on both sides of the rotating shaft. By controlling the two electric push rods, the tilt angle of the support bottom mold can be adjusted, and the two rotating electric push rods can provide stable support for the support bottom mold. The bottom mold drive can achieve rotational adjustment of the support bottom mold within a range of ±12°.

[0105] In some embodiments, the molding system further includes two sets of side mold bases 242 arranged opposite to each other, and side templates 241 are respectively disposed on the side mold bases 242 and slidably connected to the side mold bases. A side mold driving component 243 is disposed between the side mold bases 242 and the side templates 241. The side mold driving component 243 is used to drive the side templates to move in the lateral direction of the magnetic levitation track beam to realize the mold closing and mold opening operations of the side templates.

[0106] In some embodiments, a slide rail 244 is provided on the side mold base 242. The guide surface of the slide rail 244 is inclined outward and downward along the transverse direction of the track beam. A slider 245 is provided on the side template 241 to cooperate with the slide rail. The slider 245 is fitted on the slide rail 244 so that when the slider moves away from the track beam on the slide rail, the side template can move downward simultaneously. By setting the guide surface of the slide rail to an inclined structure, the side template moves downward while moving outward during demolding, which can effectively prevent interference between the functional component template 27 provided on the side template and the cast magnetic levitation track beam.

[0107] In some embodiments, referring to Figures 3 and 15, an end mold base 252 is provided at the location of the end mold 251. One end of the end mold 251 is disposed on the end mold base 252 and is connected to the end mold base 252 by a pivot sliding fit, so that the end mold can rotate around the pivot on the end mold base and slide on the end mold base in the horizontal direction.

[0108] The molding system also includes an end mold drive assembly, which includes a first end mold drive component 253 and a second end mold drive component 254, for driving the end mold plate to slide and rotate on the end mold base.

[0109] By configuring the end template to be pivotally connected to the end mold base while also being able to slide on the end mold base, during the demolding operation, the end template can first move outward and separate from the end face of the maglev track beam, and then the end template can be flipped over to achieve demolding, as shown in Figure 15. This solves the problem of interference between the end template and the maglev track beam during mold opening, which is caused by the end template having a hole template for forming the end face through hole on the track beam end face.

[0110] In some embodiments, a first end mold drive 253 is connected to the end mold 251 near the end mold base 252, and a second end mold drive 254 is connected to the end mold 251 away from the end mold base 252. Thus, during end mold demolding, the first end mold drive first moves the end mold horizontally outward to separate it from the maglev track beam, and then the second end mold drive flips the end mold.

[0111] End mold support bases 255 are provided on the outside of the end mold 251 to support the demolded end mold.

[0112] An entrance passage 211 is provided on both sides of the base 21 to facilitate personnel entry into the forming system and to facilitate operation during the forming process of the track beam.

[0113] On the other hand, based on the magnetic levitation track beam forming system in the above embodiments, the present invention also provides a method for forming a magnetic levitation spatial curved beam, comprising the following steps:

[0114] Adjust the bottom mold of the support to the same angle as the bottom surface of the formed maglev track beam support;

[0115] Then the two side templates are closed;

[0116] The stator sleeve is installed onto the functional component template. The spatial position of the functional component template is adjusted by the vertical adjustment component and the horizontal adjustment component. The position of the stator sleeve on the functional component template is detected, and the functional component template is adjusted according to the detection results until the stator sleeve is adjusted to the design position.

[0117] Position and install the L-shaped steel plate on one side of the functional component template. Fix the L-shaped steel plate to the functional component template using steel plate fasteners. Adjust the position of the L-shaped steel plate using steel plate adjusting devices. Detect the position of the L-shaped steel plate and adjust it according to the detection results until it is in the designed position.

[0118] Install the support end template, and then close the end templates at both ends;

[0119] After the casting is completed, the end templates at both ends are demolded to both ends, the connection between the functional component template and the magnetic levitation functional component is removed, and the functional component template is demolded. Then, the side templates on both sides slide to both sides to demold, and the formed magnetic levitation spatial curve beam is lifted out of the forming system.

[0120] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use. They are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0121] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not imply that the components are required to be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0122] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0123] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
