Description

Technical Field

[0001] This invention relates to the field of maglev transportation technology, and more specifically, to a micro maglev double-layer track beam and its installation and adjustment fixture. Background Technology

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

[0003] As an important branch of maglev technology, micro maglev systems typically refer to maglev transportation with relatively small capacity, short track length, and relatively simplified system structure. They place higher demands on construction costs, construction efficiency, system lightweighting, and environmental adaptability. In the construction of micro maglev systems, the track beam, as the core load-bearing and guiding reference structure of the entire system, directly determines the stability, safety, energy consumption, and long-term maintenance costs of the maglev vehicle.

[0004] However, the existing micro maglev systems have a single track beam design, typically using a single-layer track design. This makes it impossible to be compatible with straddle-type and suspended maglev vehicles on the same line, limiting the system's flexibility and preventing different types of maglev vehicles from sharing the same track beam. Summary of the Invention

[0005] In view of this, the first objective of the present invention is to provide a micro maglev double-layer track beam to at least overcome the problem that the track beams of existing micro maglev systems cannot be used simultaneously for straddle-type maglev vehicles and suspended maglev vehicles.

[0057] Example 1

[0058] Embodiment 1 of the present invention provides a micro maglev double-layer track beam 10, which is particularly a track beam that can be used for both straddle-type maglev vehicles and suspended maglev vehicles.

[0059] Figure 1 The structure of the micro-magnetic levitation double-layer track beam 10 disclosed in Embodiment 1 of the present invention is illustrated schematically. Figure 1 As shown, according to Embodiment 1 of the present invention, the micro maglev double-layer track beam 10 may include: a box girder 11, a straddle-type maglev vehicle track 12, and a suspended maglev vehicle track 13.

[0060] The box girder 11 is roughly rectangular and extends longitudinally. It is mainly used to provide a carrier for the installation of the straddle-type maglev vehicle track 12 and the suspended maglev vehicle track 13, and to serve as the load-bearing structure of the entire track beam.

[0061] It is worth noting that the vertical direction described throughout this invention can specifically refer to... Figure 1 The X-axis direction shown is the direction of travel of the maglev vehicle; the lateral direction can specifically be... Figure 1 The Y-axis direction shown; the vertical direction can specifically be... Figure 1 The Z-axis direction is shown in the figure.

[0062] The straddle-type maglev vehicle track 12 serves as the running track for the straddle-type maglev vehicle, and it is set on the top surface of the box girder 11 and extends longitudinally. The suspended maglev vehicle track 13 serves as the running track for the suspended maglev vehicle, and it is set on the bottom surface of the box girder 11 and extends longitudinally.

[0063] According to Embodiment 1 of the present invention, by setting straddle-type maglev vehicle track 12 and suspended maglev vehicle track 13 on the top and bottom surfaces of the box girder 11 respectively, straddle-type and suspended maglev vehicles can share the micro maglev double-layer track beam 10. After completion and commissioning, straddle-type maglev vehicles can travel on the top surface of the box girder 11 using straddle-type maglev vehicle track 12 as their running track, while suspended maglev vehicles can travel on the bottom surface of the box girder 11 using suspended maglev vehicle track 13 as their running track. This design achieves the goal of a single track beam compatible with the operation of dual-mode maglev vehicles, breaking through the limitation of the single track beam type in traditional micro maglev systems, improving the utilization rate of track beam resources, saving construction costs and land resources, enhancing the system's flexibility, and providing an innovative solution for the multi-functional application and future development of micro maglev systems.

[0064] In some possible embodiments, such as Figure 2 As shown, the straddle-type maglev vehicle track 12 may include multiple sleepers 121, two F-rails 122, and a straddle-type maglev vehicle induction plate 123.

[0065] Multiple sleepers 121 are sequentially fixed to the top surface of the box girder 11 along the longitudinal direction. Exemplarily, each sleeper 121 may have a concrete support platform 124 fixed to the top surface of the box girder 11 at its bottom, with each sleeper 121 supported by its own concrete support platform 124. Two F-rails 122 are symmetrically distributed on both sides of the box girder 11 in the transverse direction. Each F-rail 122 extends longitudinally and is supported by multiple sleepers 121. Simultaneously, each F-rail 122 has a straddle-type maglev vehicle induction plate 123 on its top surface.

[0066] The two F-rails 122 are mainly used to cooperate with the corresponding levitation electromagnets located on the straddle-type maglev vehicle to provide the straddle-type maglev vehicle with levitation force to levitate it above the box girder 11 and guide force to guide the straddle-type maglev vehicle. The straddle-type maglev vehicle induction plate 123 is mainly used to cooperate with the linear motor on the straddle-type maglev vehicle to provide the traction force required for the straddle-type maglev vehicle to move.

[0067] In some possible embodiments, such as Figure 2 As shown, the suspended maglev vehicle track 13 may include two U-shaped rails 131 and a suspended maglev vehicle induction plate 132. The two U-shaped rails 131 are symmetrically distributed on both sides of the box girder 11 in the transverse direction. Each U-shaped rail 131 extends longitudinally and is fixedly connected to the bottom surface of the box girder 11. The suspended maglev vehicle induction plate 132 is disposed between the two U-shaped rails 131. The suspended maglev vehicle induction plate 132 extends longitudinally and is fixedly connected to the bottom surface of the box girder 11.

[0068] The two U-shaped rails 131 are mainly used to cooperate with the corresponding levitation electromagnets located on the suspended maglev vehicle to provide the suspended maglev vehicle with levitation force to levitate it below the box girder 11 and guide force to guide the suspended maglev vehicle. The suspended maglev vehicle induction plate 132 is used to cooperate with the linear motor on the suspended maglev vehicle to provide the traction force required for the suspended maglev vehicle to move.

[0069] Example 2

[0070] Based on Embodiment 1, the inventors of this invention further discovered that in the prior art, there are only tooling fixtures suitable for installing single-layer track beams. For the micro maglev double-layer track beam 10 provided in Embodiment 1 of this invention, there is currently no corresponding tooling fixture that can cooperate with it to achieve fast and accurate installation of the micro maglev double-layer track beam 10.

[0071] Therefore, Embodiment 2 of the present invention provides an installation and adjustment fixture 20, which is applied to the micro maglev double-layer track beam 10 disclosed in Embodiment 1, in order to enable the micro maglev double-layer track beam 10 to be installed quickly and accurately.

[0072] It is worth noting that the installation described in Embodiment 2 of the present invention is not a process of assembling the various parts constituting the micro maglev double-layer track beam 10 together to form a complete micro maglev double-layer track beam 10, but rather a process of installing the assembled complete micro maglev double-layer track beam 10 at a predetermined position on the maglev line.

[0073] Figure 3 The structure of the installation and adjustment fixture 20 provided in Embodiment 2 of the present invention is illustrated schematically. Figure 4 for Figure 3 The diagram shown is a reference for the use of the installation and adjustment fixture 20. Figure 5 for Figure 4 A sectional view.

[0074] like Figure 3 As shown in Embodiment 2 of the present invention, the installation and adjustment fixture 20 may include two end support units 21 and a plurality of middle support units 22.

[0075] Two end support units 21 are respectively disposed at both ends of the box girder 11 in the longitudinal direction to provide support for the box girder 11 from both ends in the longitudinal direction. Each end support unit 21 includes an end drive assembly 211 disposed below the box girder 11. The end drive assembly 211 is configured to output a vertical reciprocating motion, and the output end of the end drive assembly 211 is aligned with the bottom surface of the box girder 11, so that the end drive assembly 211 can selectively apply an upward vertical force to the box girder 11.

[0076] Among them, reference Figure 6 As shown, the end drive assembly 211 may include two hydraulic jacks arranged side by side, and the output ends of the two hydraulic jacks may be connected to a plate, which is used to contact the box girder 11.

[0077] Several central support units 22 are arranged longitudinally between two end support units 21. Exemplarily, the accompanying drawings of the present invention show a configuration with three central support units 22; however, the number of central support units 22 may be more or fewer, and this is not limited here.

[0078] Each central support unit 22 may include a first central drive assembly 221 and two second central drive assemblies 222.

[0079] The first central drive assembly 221 is disposed below the box girder 11 and configured to output reciprocating motion in the vertical direction. The output end of the first central drive assembly 221 is aligned with the bottom surface of the box girder 11 between the U-shaped rail 131 and the suspended maglev vehicle induction plate 132 of the suspended maglev vehicle track 13, so that the first central drive assembly 221 can selectively apply an upward vertical force to the box girder 11 without affecting the suspended maglev vehicle track 13 on the bottom surface of the box girder 11.

[0080] Reference Figure 7 As shown, the first central drive assembly 221 may include two hydraulic jacks arranged side by side. Furthermore, the output end of one of the hydraulic jacks in the first central drive assembly 221 is aligned with the bottom surface of the box girder 11 located between one of the U-shaped rails 131 and the suspended maglev vehicle induction plate 132 of the suspended maglev vehicle track 13, and the output end of the other hydraulic jack in the first central drive assembly 221 is aligned with the bottom surface of the box girder 11 located between the other U-shaped rail 131 and the suspended maglev vehicle induction plate 132 of the suspended maglev vehicle track 13.

[0081] Two second central drive components 222 are symmetrically distributed on both sides of the box girder 11 in the transverse direction. Each second central drive component 222 is configured to output a reciprocating motion in the transverse direction toward the other second central drive component 222, and the output end of each second central drive component 222 is aligned with the corresponding side of the box girder 11. Through the cooperation of the two second central drive components 222, the position of the box girder 11 in the transverse direction can be adjusted.

[0082] Continue to refer to Figure 7 Each of the second central drive components 222 may include two hydraulic jacks arranged sequentially from top to bottom.

[0083] Based on the above settings, when actually using the installation and adjustment fixture 20 disclosed in the embodiments of the present invention, first refer to... Figure 3 The structure shown allows the components of the installation and adjustment fixture 20 to be installed at predetermined positions on the construction site, and the positions of each component to be adjusted according to the length of the micro maglev double-layer track beam 10, so that the distance between the two end support units 21 is approximately equal to the length of the micro maglev double-layer track beam 10.

[0084] Subsequently, the output ends of the end drive components 211 of the two end support units 21 and the output ends of the first middle drive components 221 of each middle support unit 22 are aligned to be in the same horizontal plane. Then, refer to... Figure 4 and Figure 5As shown, the assembled micro-magnetic levitation double-layer track beam 10 is hoisted onto the installation and adjustment fixture 20 using lifting equipment such as a crane, so that the two ends of the box beam 11 in the longitudinal direction are respectively supported by the output ends of the end drive components 211 of the two end support units 21, and the middle area of ​​the bottom surface of the box beam 11 is supported by the output ends of the first middle drive components 221 of each middle support unit 22, and the box beam 11 is located between the two second middle drive components 222 of each middle support unit 22.

[0085] Based on this, a lateral force can be applied to the side of the box girder 11 by the two second central drive components 222 of each central support unit 22 to adjust the lateral position of the box girder 11. Additionally, a vertical force can be simultaneously applied to the bottom surface of the box girder 11 by the end drive components 211 of the end support unit 21 and the first central drive components 221 of each central support unit 22 to adjust the vertical position of the box girder 11. When adjusting the vertical position of the box girder 11, the box girder 11 can be limited by the two second central drive components 222 of each central support unit 22, thereby maintaining the lateral position of the box girder 11 unchanged during precise adjustment of its vertical position.

[0086] According to Embodiment 2 of the present invention, through the coordinated operation of the end support unit 21 and the middle support unit 22, sufficient support force is provided for the micro maglev double-layer track beam 10, while the vertical and lateral positions of the track beam can be precisely adjusted. This makes the track beam less prone to slippage during installation, ensuring high installation accuracy and minimizing deformation, thus improving the safety and accuracy of installation. Furthermore, when the micro maglev double-layer track beam 10 is supported by the installation and adjustment fixture 20, the fixture does not obstruct the top and bottom surfaces of the track beam, thereby not affecting the installation of other accessories (such as sensors) on the track beam, and thus enabling efficient and precise completion of the track beam installation.

[0087] In some possible embodiments, such as Figure 6 As shown, the end support unit 21 may further include two gantry frames 212 and an end crossbeam 213.

[0088] Two gantry frames 212 are arranged laterally opposite each other on both sides of the box girder 11. The two ends of the end crossbeam 213 are respectively connected to the two gantry frames 212. The end drive assembly 211 is mounted on the end crossbeam 213.

[0089] This design can effectively improve the structural strength of the end support unit 21, which is conducive to improving the support force provided by the end drive assembly 211 to the box girder 11, ensuring that both ends of the box girder 11 can be reliably supported by the end drive assemblies 211 of the two end support units 21, and will not cause too much interference to the installation of the track beam.

[0090] In some possible embodiments, such as Figure 2 or Figure 5 As shown, the box girder 11 has a protrusion 111 at its longitudinal end. The bottom surface of the protrusion 111 is higher than the bottom surface of the box girder 11 in the vertical direction; that is, the protrusion 111 can be an upwardly recessed structure. The output end of the end drive assembly 211 is aligned with the bottom surface of the protrusion 111. This design ensures that the output end of the end drive assembly 211 is substantially in contact with the bottom surface of the protrusion 111 on the box girder 11, thereby preventing the end drive assembly 211 from affecting the suspended maglev vehicle track 13 on the bottom surface of the box girder 11.

[0091] In some possible embodiments, such as Figure 7 As shown, the central support unit 22 may further include a central support beam 223, a central crossbeam 224, and two central vertical beams 225.

[0092] The central crossbeam 224 extends laterally and is supported below the box girder 11 by the central support beam 223. Two central vertical beams 225 are arranged laterally opposite to each other on the central crossbeam 224 and are located on both sides of the box girder 11. The two central vertical beams 225 correspond to two second central drive assemblies 222 respectively. Each second central drive assembly 222 is located on the corresponding central vertical beam 225. A first central drive assembly 221 is located on the central crossbeam 224 and between the two central vertical beams 225.

[0093] This design enhances the structural strength of the central support unit 22, enabling it to provide reliable support for the box girder 11, while minimizing its obstruction of the micro maglev double-deck track beam 10, thereby facilitating the installation of other accessories on the micro maglev double-deck track beam 10.

[0094] Furthermore, the central support unit 22 may also include reinforcing beams 226 corresponding to the central upright beams 225. The reinforcing beams 226 are inclined, with the higher end of the reinforcing beams 226 connected to the outer side of the corresponding central upright beams 225, and the lower end of the reinforcing beams 226 connected to the central crossbeams 224.

[0095] By strengthening the beam 226, the lateral bearing capacity of the central vertical beam 225 can be effectively improved, thereby enabling the second central drive assembly 222 to reliably apply lateral force to the side of the box girder 11.

[0096] In some possible embodiments, the installation and adjustment fixture 20 may also include several bottom support units 23.

[0097] Combination Figure 3 As shown, several bottom support units 23 are arranged longitudinally between two end support units 21. For example, a bottom support unit 23 can be arranged between each pair of adjacent middle support units 22.

[0098] The bottom support unit 23 includes a first bottom drive assembly 231 disposed below the box girder 11. The first bottom drive assembly 231 is configured to output a vertical reciprocating motion. The output end of the first bottom drive assembly 231 is aligned with the bottom surface of the box girder 11 between the U-shaped rail 131 and the suspended maglev vehicle induction plate 132 of the suspended maglev vehicle track 13, so that the first bottom drive assembly 231 can selectively apply an upward vertical force to the box girder 11 without affecting the suspended maglev vehicle track 13 on the bottom surface of the box girder 11.

[0099] Reference Figure 8 As shown, the first bottom drive assembly 231 may include two hydraulic jacks arranged side by side. Furthermore, the output end of one of the hydraulic jacks in the first bottom drive assembly 231 is aligned with the bottom surface of the box girder 11 located between one of the U-shaped rails 131 and the suspended maglev vehicle induction plate 132 of the suspended maglev vehicle track 13, and the output end of the other hydraulic jack in the first bottom drive assembly 231 is aligned with the bottom surface of the box girder 11 located between the other U-shaped rail 131 and the suspended maglev vehicle induction plate 132 of the suspended maglev vehicle track 13.

[0100] It is worth noting that by setting the bottom support unit 23, the first bottom drive component 231, together with the end drive component 211 and the first middle drive component 221, can reliably support the box girder 11 from below, thereby further improving the support force provided by the entire installation and adjustment fixture 20 to the micro maglev double-layer track beam 10, and further improving the stability of the micro maglev double-layer track beam 10 after being supported.

[0101] In some possible embodiments, such as Figure 8 As shown, the bottom support unit 23 may also include a bottom support frame 232, a second bottom drive assembly 233, and a bottom lifting plate 234.

[0102] The bottom support frame 232 is generally U-shaped and is located below the box girder 11. The second bottom drive assembly 233 is mounted on the bottom support frame 232 and is configured to output reciprocating motion in the vertical direction. Exemplarily, the second bottom drive assembly 233 may include multiple, such as six hydraulic jacks arranged in a transverse sequence.

[0103] The bottom lifting plate 234 is located at the output end of the second bottom drive assembly 233, enabling it to reciprocate vertically under the drive of the second bottom drive assembly 233. The first bottom drive assembly 231 is mounted on the bottom lifting plate 234.

[0104] This design creates a bottom support unit 23 that can be adjusted in stages. The second bottom drive assembly 233 can not only dynamically adjust the vertical position of the first bottom drive assembly 231 to adapt to different ground conditions, but also enable the bottom support unit 23 to effectively cope with complex working conditions such as deformation of the box girder 11 and uneven ground. This reduces the load on a single drive assembly and the required stroke, improving equipment reliability and service life while ensuring construction quality. It provides a more complete solution for the high-precision installation of the micro maglev double-layer track beam 10.

[0105] 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.
