Description

Technical Field

[0001] This invention relates to the field of maglev system technology, and in particular, to a maglev adjustable track assembly and its construction method. Background Technology

[0002] Currently, existing medium- and low-speed maglev systems use an F-rail structure. The F-rail is rolled and then machined in the factory to assemble prefabricated track panels. These prefabricated track panels are then transported to the site for installation. On-site installation requires adjusting the prefabricated track panels to the correct installation precision using tooling before casting concrete support platforms to support them. This complex manufacturing process, high precision requirements, and high cost hinder the widespread application of medium- and low-speed maglev. Existing integrated beam-rail structures directly install the track onto a track slab, replacing the traditional F-type track structure and eliminating H-type sleepers, fasteners, and support platforms. This reduces the amount of structural engineering work on bridges and tracks, aiming to lower project investment. However, integrated beam-rail structures present technical challenges, including high track installation precision requirements leading to difficult construction, actual installation accuracy falling below design precision, and the inability to make adjustments later.

[0003] Therefore, it is necessary to propose a magnetic levitation adjustable track assembly to solve, at least partially, the technical problems of low installation accuracy and difficult maintenance of existing integrated beam-track structures. Summary of the Invention

[0004] The adjustable track assembly for maglev provided by this invention solves the problems of high track construction difficulty and inability to adjust it later in existing beam-track integrated structures.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A magnetic levitation adjustable track assembly includes a beam, a track connection pre-embedded assembly, a track installation assembly, and a U-shaped track segment. Two sets of the track connection pre-embedded assemblies are arranged opposite each other on the transverse sides of the beam. One end of each track connection pre-embedded assembly is embedded in the beam, and the other end protrudes from the side wall of the beam and cantilevered outwards. The track installation assembly, the U-shaped track segment, and the track connection pre-embedded assembly are arranged in a corresponding manner. The track installation assembly is detachably mounted on the cantilevered end of the corresponding track connection pre-embedded assembly. The U-shaped track segment is suspended on the corresponding track installation assembly, with the opening of the U-shaped track segment facing downwards. The closed top of the U-shaped track segment is detachably connected to the corresponding track installation assembly. The first connecting end of the track installation assembly for cooperating with the track connection pre-embedded assembly is adjustable in height relative to the track connection pre-embedded assembly and connected by a first fastener. The second connecting end of the U-shaped track segment for cooperating with the track installation assembly is adjustable in the transverse direction and connected by a second fastener.

[0007] Furthermore, the magnetic levitation adjustable track assembly also includes a sliding plate arranged longitudinally, the sliding plate being embedded in the top of the beam and exposed externally, with two sliding plates positioned opposite each other on both sides of the beam.

[0008] Furthermore, the track mounting assembly includes multiple track mounting components arranged longitudinally at intervals, and the multiple track mounting components together hoist one U-shaped track segment.

[0009] The first connecting end of the track mounting component is provided with a vertical waist-shaped hole, and the second connecting end of the track mounting component is provided with a horizontal waist-shaped hole. The first fastener passes through the vertical waist-shaped hole and is fixedly connected to the track connection pre-embedded component, and the second fastener passes through the horizontal waist-shaped hole and is fixedly connected to the U-shaped rail segment.

[0010] Furthermore, the track mounting component includes a beam connecting plate, a top plate, and a bottom plate. The top plate and the bottom plate are disposed opposite each other at the vertical ends of the beam connecting plate along the height direction of the beam connecting plate. The top plate, the bottom plate, and the beam connecting plate are reinforced and connected by a web plate and stiffening plates. The beam connecting plate is provided with vertically extending oblong holes. The beam connecting plate is attached to the cantilever end wall of the track connecting embedded component. The first fastener passes through the vertical oblong holes and cooperates with the cantilever end of the track connecting embedded component to fix the beam connecting plate on the track connecting embedded component. The bottom plate is provided with transversely extending oblong holes. The second fastener passes through the transverse oblong holes and cooperates with the U-shaped rail segment to hoist the U-shaped rail segment onto the bottom plate.

[0011] Furthermore, the track mounting component also includes a limiting constraint plate, which is disposed on the top plate and has a gap with the beam connecting plate, thereby forming a lateral constraint hook for the track mounting component. The limiting constraint plate is disposed on the side of the beam connecting plate near the track connection embedded component.

[0012] Furthermore, the track mounting component also includes a height adjuster, and the top plate is provided with a height adjustment threaded hole arranged through the height direction. The height adjuster is threadedly engaged with the height adjustment threaded hole, and the height adjuster is arranged through the height adjustment threaded hole to abut against the top surface of the cantilever end of the track connection embedded component.

[0013] Furthermore, the track connection pre-embedded assembly includes multiple track connection pre-embedded parts arranged longitudinally at intervals. Each track connection pre-embedded part includes a fixedly connected pre-embedded connection part and a suspension connection part. The pre-embedded connection part is embedded in the beam body, and the suspension connection part is located on the outside of the beam body. The suspension connection part is a rectangular frame structure. The track mounting component is arranged one-to-one with the track connection pre-embedded part. The track mounting component is detachably mounted on the corresponding rectangular frame structure. The outer side of the rectangular frame structure is located between the limiting constraint plate and the beam connection plate. The height adjustment threaded hole is further provided. The pre-embedded connection part includes an upper anchor bolt, a shear key, and a lower anchor bolt arranged sequentially from top to bottom along the height direction. The upper anchor bolt, the shear key, and the lower anchor bolt are respectively connected to the inner side of the rectangular frame structure.

[0014] Furthermore, the U-shaped rail segment includes a U-shaped rail segment, a sensing plate, a third fastener, and a mounting plate. The U-shaped rail segment is suspended on the rail mounting component and arranged with its open side facing downwards. The mounting plate is located inside the U-shaped rail segment via the third fastener, and the sensing plate is located on the mounting plate.

[0015] This invention also provides a construction method for a magnetic levitation adjustable track assembly, comprising the following steps:

[0016] S10, prepare a beam body, with sliding plates pre-embedded on both sides of the top of the beam body, and rail connection pre-embedded parts pre-embedded on both sides of the beam body respectively. The cantilevered ends of the rail connection pre-embedded parts extend outward in the lateral direction and are cantilevered. Multiple rail connection pre-embedded parts are arranged at intervals in the longitudinal direction.

[0017] Pre-assembled rail panels are made by pre-positioning and assembling U-shaped rail segments with corresponding multiple rail mounting parts using second fasteners. The second fasteners pass through the transverse waist-shaped holes of the corresponding rail mounting parts and cooperate with the U-shaped rail segments for pre-positioning and assembly.

[0018] S20, hoist the beam to the predetermined position and adjust it into place; pre-assemble the pre-assembled rail panel to the cantilever end of the rail connection embedded part, hang the pre-assembled rail panel on the cantilever end through the lateral constraint hook of the rail installation part, and pre-position the middle part of the rail installation part with the rail connection embedded part through the first fastener.

[0019] S30, with the first fastener passing through the vertical waist-shaped hole of the corresponding track mounting part and cooperating with the cantilever end wall of the track connection embedded part, the height adjuster is used to drive the track mounting part to move vertically to the design elevation position and tighten the first fastener to lock and fix it.

[0020] With the second fastener passing through the transverse waist-shaped hole of the corresponding rail mounting component and engaging with the U-shaped rail segment, the U-shaped rail segment is driven to move laterally to the designed lateral position and the second fastener is tightened for locking and fixing.

[0021] The present invention has the following beneficial effects:

[0022] The adjustable track assembly for maglev of the present invention includes a beam and a track connection pre-embedded assembly, a track installation assembly, and a U-shaped track segment respectively disposed on both sides of the beam. One end of the track connection pre-embedded assembly is embedded in the beam, and the other end of the track connection pre-embedded assembly extends laterally and is cantilevered. The first connecting end of the track installation assembly is detachably mounted on the cantilevered end by a first fastener, and its installation position is adjustable along the elevation direction. The U-shaped track segment is detachably suspended from the second end of the track installation assembly by a second fastener, and its installation position is adjustable along the lateral direction. The track connection pre-embedded assembly is pre-embedded during the preparation of the beam. A pre-embedded track connection component is provided. The U-shaped track segment and the track installation component are pre-positioned and assembled to form a pre-assembled track panel using a second fastener. The pre-assembled track panel can be adjusted up and down relative to the beam, and the U-shaped track segment can be adjusted left and right relative to the beam. Compared with existing maglev track components, the U-shaped track segment of this invention can be adjusted in both up and down and left and right directions. The track installation reduces the dependence on the manufacturing precision of the beam, reduces the manufacturing precision of the beam, and significantly reduces the project cost. The project cost is reduced by at least one-third compared with existing maglev track components, and independent maintenance can be achieved later.

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9According to one embodiment of the present invention, a magnetic levitation adjustable track assembly 100 includes a beam 10, a track connection pre-embedded assembly 20, a track installation assembly 30, and a U-shaped track segment 40. Two sets of the track connection pre-embedded assemblies 20 are disposed opposite each other on the lateral sides of the beam 10. One end of each track connection pre-embedded assembly 20 is embedded in the beam 10, and the other end protrudes from the side wall of the beam 10 and cantilevered outward. The track installation assembly 30, the U-shaped track segment 40, and the track connection pre-embedded assembly 20 are arranged in a one-to-one correspondence. The track installation assembly 30 is detachably mounted on the corresponding track connection... On the cantilever end of the pre-embedded component 20, the U-shaped rail segment 40 is suspended on the corresponding rail mounting component 30. The opening of the U-shaped rail segment 40 is arranged downward, and the closed top of the U-shaped rail segment 40 is detachably connected to the corresponding rail mounting component 30. The first connecting end of the rail mounting component 30 for cooperating with the rail connection pre-embedded component 20 is adjustable in height relative to the rail connection pre-embedded component 20 and connected by a first fastener 50. The second connecting end of the U-shaped rail segment 40 for cooperating with the rail mounting component 30 is adjustable in the lateral direction and connected by a second fastener 60.

[0041] The adjustable track assembly 100 of the present invention includes a beam 10 and a track connection pre-embedded assembly 20, a track installation assembly 30, and a U-shaped track segment 40 respectively disposed on both sides of the beam 10. One end of the track connection pre-embedded assembly 20 is embedded in the beam 10, and the other end of the track connection pre-embedded assembly 20 extends laterally and is cantilevered. The first connecting end of the track installation assembly 30 is detachably mounted on the cantilevered end by a first fastener 50, and its installation position is adjustable along the elevation direction. The U-shaped track segment 40 is detachably suspended from the second end of the track installation assembly 30 by a second fastener 60, and its installation position is adjustable along the lateral direction. When preparing the beam body 10, a track connection pre-embedded component 20 is pre-installed. The U-shaped rail segment 40 and the track installation component 30 are pre-positioned and assembled to form a pre-assembled rail panel using the second fastener 60. The pre-assembled rail panel can be adjusted up and down relative to the beam body 10, and the U-shaped rail segment 40 can be adjusted left and right relative to the beam body 10. Compared with existing maglev track functional components, the U-shaped rail segment of this invention can be adjusted in both up and down and left and right directions. The track installation reduces the dependence on the manufacturing precision of the beam body, reduces the manufacturing precision of the beam body, and significantly reduces the project cost. The project cost is reduced by at least one-third compared with existing maglev track functional components, and independent maintenance can be achieved later.

[0042] Research has revealed that existing maglev track components adopt a continuous structure. The design and assembly of these components focus on ensuring the installation accuracy of the track based on machining and construction precision, without considering ease of construction, ease of maintenance, or project cost. In existing solutions, pre-assembled track sections are precisely positioned during fabrication, and on-site construction also involves precise positioning and assembly. This makes it difficult to make adaptive adjustments during on-site construction, and subsequent maintenance is challenging and costly.

[0043] Understandably, in the present invention, the two sides of the beam 10 are respectively provided with rail connection embedded components 20, and the cantilever end of each side of the rail connection embedded component 20 is respectively provided with rail installation component 30 and U-shaped rail segment 40; the rail connection embedded component 20 is formed by combining multiple rail connection embedded parts 21; the rail installation component 30 is formed by combining multiple rail installation parts 31, and the rail installation parts 31 are arranged correspondingly with the rail connection embedded parts 21; the U-shaped rail segment 40 is a whole segment structure.

[0044] Understandably, the installation position of the track mounting assembly 30 is adjustable along the elevation direction. It can be that a vertical oblong hole 301 is arranged at the cantilever end of the track connecting pre-embedded assembly 20, and a first connecting hole is arranged on the first end of the track mounting assembly 30, with the first fastener 50 passing through the vertical oblong hole 301 and threadedly connected to the first connecting hole; alternatively, a first connecting hole can be arranged at the cantilever end of the track connecting pre-embedded assembly 20, and a vertical oblong hole 301 is arranged on the first end of the track mounting assembly 30, with the first fastener 50 passing through the vertical oblong hole 301 and threadedly connected to the first connecting hole; or vertical oblong holes 301 can be arranged at both the cantilever end and the first end of the track mounting assembly 30.

[0045] Understandably, the second end of the U-shaped rail segment 40 relative to the rail mounting assembly 30 can be adjusted left and right. This can be achieved by: a transverse oblong hole 302 being arranged on the U-shaped rail segment 40; a second connecting hole being arranged on the second end of the rail mounting assembly 30; and a second fastener 60 passing through the transverse oblong hole 302 and threadedly engaging with the first connecting hole. Alternatively, a second connecting hole can be arranged on the U-shaped rail segment 40; a transverse oblong hole 302 can be arranged on the second end of the rail mounting assembly 30; and a second fastener 60 passing through the transverse oblong hole 302 and threadedly engaging with the first connecting hole. Furthermore, both the second ends of the U-shaped rail segment 40 and the rail mounting assembly 30 can be provided with transverse oblong holes 302.

[0046] Furthermore, the magnetic levitation adjustable track assembly 100 also includes a longitudinally arranged sliding plate 70, which is embedded in the top of the beam 10 and exposed externally. Two sliding plates 70 are arranged opposite each other on both sides of the beam 10. In a specific embodiment of the present invention, the sliding plate 70 is embedded in the top surface of the beam 10 and is arranged near the edge of the beam 10. By adopting the design of separating the sliding plate 70 from the track, friction between the skid and the track can be avoided when the vehicle uses skid braking and stopping, reducing track wear and extending the service life of the track.

[0047] Please refer to this again. Figure 3 , Figure 4 , Figure 5 and Figure 6 Furthermore, the track mounting assembly 30 includes multiple track mounting members 31 arranged longitudinally at intervals. These multiple track mounting members 31 jointly hoist a U-shaped track segment 40. Each track mounting member 31 has a first connecting end with a vertical oblong hole 301 and a second connecting end with a horizontal oblong hole 302. A first fastener 50 passes through the vertical oblong hole 301 and is fixedly connected to the track connection pre-embedded assembly 20. A second fastener 60 passes through the horizontal oblong hole 302 and is fixedly connected to the U-shaped track segment 40. By providing the vertical oblong hole 301 and the horizontal oblong hole 302, the U-shaped track segment 40 can be independently adjusted in both vertical and horizontal directions relative to the beam 10, reducing the dependence of the U-shaped track segment 40 installation on the manufacturing precision of the beam 10.

[0048] Further, the track mounting component 31 includes a beam connecting plate 311, a top plate 312, and a bottom plate 313. The top plate 312 and the bottom plate 313 are disposed opposite each other at the vertical ends of the beam connecting plate 311 along the height direction of the beam connecting plate 311. The top plate 312, the bottom plate 313, and the beam connecting plate 311 are reinforced and connected by a web plate 314 and a stiffening plate 315. The beam connecting plate 311 is provided with vertically extending oblong holes 301. The beam connecting plate 311 is attached to... Arranged on the cantilever end wall of the track connection embedded component 21, the first fastener 50 passes through the vertical waist-shaped hole 301 and cooperates with the cantilever end of the track connection embedded component 20 to fix the beam connecting plate 311 on the track connection embedded component 20. The bottom plate 313 is provided with the transverse waist-shaped hole 302 extending laterally. The second fastener 60 passes through the transverse waist-shaped hole 302 and cooperates with the U-shaped rail segment 40 to hoist the U-shaped rail segment 40 onto the bottom plate 313.

[0049] Furthermore, the track mounting component 31 also includes a limiting constraint plate 316, which is disposed on the top plate 312 and has a gap between it and the beam connecting plate 311, thereby enabling the track mounting component 30 to form a lateral constraint hook. The limiting constraint plate 316 is disposed on the side of the beam connecting plate 311 near the track connection embedded component 20.

[0050] Understandably, the limiting constraint plate 316 is provided on the top plate 312 and has a gap between it and the beam connecting plate 311, so that the track installation assembly 30 forms a lateral constraint hook. The lateral constraint hook has a temporary suspension function for assembly and a lateral auxiliary limiting function when the first fastener 50 is loose, which is beneficial to improving the convenience of pre-assembled track panel installation and the safety of the entire track.

[0051] Furthermore, the track mounting component 31 also includes a height adjuster 80. The top plate 312 has a height-adjusting threaded hole extending through it in the height direction. The height adjuster 80 is threaded into the height-adjusting threaded hole and is positioned through the hole to abut against the top surface of the cantilevered end of the track connection embedded component 20. Understandably, in this invention, the position of the height adjuster 80 is adjusted after complete positioning and assembly to avoid interference between the height adjuster 80 and other components.

[0052] Please refer to this again. Figure 3 , Figure 7 and Figure 8 Furthermore, the track connection embedded assembly 20 includes a plurality of track connection embedded parts 21 arranged longitudinally at intervals. Each track connection embedded part 21 includes a fixedly connected embedded connection part and a suspension connection part. The embedded connection part is embedded in the beam body 10, and the suspension connection part is located on the outside of the beam body 10. The suspension connection part is a rectangular frame structure 214. The track mounting part 31 is arranged in a one-to-one correspondence with the track connection embedded part 21. The track mounting part 31 is detachably mounted on the corresponding rectangular frame structure 214. The outer side of the rectangular frame structure 214 is located between the limiting constraint plate 316 and the beam connecting plate 311. The height adjustment threaded hole is located above the connecting side of the rectangular frame structure 214.

[0053] Understandably, in the solution of the present invention, the track connection embedded component 20 is preferably a casting, and the alternative is a welded component.

[0054] Furthermore, the pre-embedded connection includes an upper anchor bolt 211, a shear key 212, and a lower anchor bolt 213 arranged sequentially from top to bottom along the height direction. The upper anchor bolt 211, the shear key 212, and the lower anchor bolt 213 are respectively connected to the inner side of the rectangular frame structure 214. Understandably, in order to reduce stress concentration, the outer side of the rectangular frame structure 214 has an open section in this invention.

[0055] Furthermore, the U-shaped rail segment 40 includes a U-shaped rail segment 41, a third fastener 43, a sensing plate 42, and a mounting plate 44. The U-shaped rail segment 41 is suspended on the rail mounting component 31 and arranged with the open side facing downward. The mounting plate 44 is located inside the U-shaped rail segment 41 through the third fastener 43, and the sensing plate 42 is located on the mounting plate 44. Optionally, the mounting plate 44 is a fish-shaped plate, and the induction plate 42 is located at the bottom of the mounting plate 44. In a specific embodiment of the present invention, the U-shaped rail segment 40 includes a U-shaped rail segment 41, a third fastener 43, an induction plate 42, and a mounting plate 44. The mounting plate 44 is fixed inside the U-shaped rail segment 41 by pins, and the linear motor stator of the induction plate 42 is fixed to the mounting plate by pins. The track adopts a U-shaped rail, which has a simple structure, few processing surfaces, and low cost. Setting the induction plate 42 inside the U-shaped rail can greatly improve the traction efficiency of the maglev train, reduce the energy consumption of the maglev train, and reduce the operating cost.

[0056] In a specific embodiment of the present invention, stiffening plate 315 is used to fix the bottom plate 313 and the beam connecting plate 311. The stiffening plate 315 is located on one side of the track connecting embedded part 21. Web plate 314 is used to fix the bottom plate 313 and the top plate 312 to the beam connecting plate 311 respectively. Web plate 314 is located on the middle section of the beam body 10 connecting plate and on the side of the beam body 10 connecting plate away from the track connecting embedded part 21. The stiffening plate 315 is close to the bottom plate 313 and the top plate 312, leaving a clearance gap so that the beam connecting plate 311 can fit the outer side of the rectangular frame structure 214. Specifically, the beam connecting plate 311 is provided with two rows of vertical waist-shaped holes 301, which are arranged opposite to each other on both sides of the web plate 314. Each row of vertical waist-shaped holes 301 includes two vertical waist-shaped holes 301 arranged at intervals along the height direction. The first fastener 50 is a fastening screw arranged one-to-one with the vertical waist-shaped holes 301. Fastening connection holes are arranged on the outer side of the rectangular frame structure 214. The bottom plate 313 is provided with four horizontal waist-shaped holes 302, which are respectively located at the corner positions of the bottom plate 313. The second fastener 60 is a fastening screw arranged one-to-one with the vertical waist-shaped holes 301.

[0057] The present invention also provides a construction method for a magnetic levitation adjustable track assembly 100, comprising the following steps:

[0058] S10, prepare beam body 10, with sliding plates 70 pre-embedded on both sides of the top of beam body 10, and track connecting pre-embedded parts 21 pre-embedded on both sides of beam body 10. The cantilever end of the track connecting pre-embedded part 21 extends outward in the lateral direction and is cantilevered. Multiple track connecting pre-embedded parts 21 are arranged at intervals in the longitudinal direction.

[0059] To manufacture a pre-assembled rail panel, the U-shaped rail segment 40 and the corresponding multiple rail mounting parts 31 are pre-positioned and assembled using a second fastener 60 to form a pre-assembled rail panel. The second fastener 60 passes through the transverse waist-shaped hole 302 of the corresponding rail mounting part 31 and cooperates with the U-shaped rail segment 40 for pre-positioning and assembly.

[0060] S20, hoist the beam 10 to the predetermined position and adjust it into place; pre-assemble the pre-assembled rail panel to the cantilever end of the rail connection embedded part 21, wherein the pre-assembled rail panel is hung on the cantilever end by the lateral constraint hook of the rail mounting part 31, and the middle part of the rail mounting part 31 is pre-positioned and assembled with the rail connection embedded part 21 by the first fastener 50.

[0061] S30, with the first fastener 50 passing through the vertical waist-shaped hole 301 of the corresponding track mounting part 31 and cooperating with the cantilever end wall of the track connection embedded part 21, the track mounting part 31 is driven to move vertically to the design elevation position by the height adjuster 80 and then locked and fixed by tightening the first fastener 50.

[0062] With the second fastener 60 passing through the lateral waist-shaped hole 302 of the corresponding rail mounting member 31 and engaging with the U-shaped rail segment 41, the U-shaped rail segment 41 is driven to move laterally to the designed lateral position and then locked and fixed by tightening the second fastener 60.

[0063] Understandably, in one specific implementation, pre-assembled rail panels are manufactured in a factory, and then the pre-assembled rail panels are hoisted and installed as a whole. High-precision adjustments are made based on the vertical waist-shaped holes (upper and lower waist-shaped holes), and then the track gauge is measured. If the track gauge cannot meet ±1, high-precision adjustments are made based on the horizontal waist-shaped holes (left and right waist-shaped holes).

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
