Abstract
Description
Technical Field

[0002] Superconducting maglev trains achieve contactless levitation of the train body through a strong magnetic field generated by superconducting materials, while simultaneously being propelled by an electric drive system. By completely eliminating the mechanical friction caused by wheel-rail contact, this new mode of transportation not only meets the operational stability requirements of high-speed maglev trains at speeds of 600 km / h and above, but also significantly reduces energy loss during operation, offering advantages such as high speed, low energy consumption, and environmental friendliness.
[0003] When the superconducting maglev track structure adopts an open maglev structure, the maglev train will generate significant aerodynamic noise during operation, which will seriously affect the surrounding environment. In order to reduce the impact of aerodynamic noise, a tube-type structure can be used to isolate the train body from the outside world. However, it is difficult to set up rescue channels in the tube-type maglev track structure. If the train malfunctions, how to rescue the train becomes one of the primary issues. Utility Model Content

[0038] Example:
[0039] Please see Figures 1-3 The preferred embodiment of the present invention includes a pipeline-type superconducting maglev track system with a rescue channel, comprising a roadbed structure 1, a pipeline 2, and an inflatable slide 3.
[0040] The roadbed structure 1 includes a rail support beam 11 and a support plate 12. Multiple support plates 12 are longitudinally spaced below the rail support beam 11, and side ditch platforms 13 are provided on both sides of the support plates 12. The pipeline 2 is longitudinally installed on the rail support beam 11. Multiple safety doors 4 are longitudinally spaced on the side wall of the pipeline 2 near the side ditch platform 13. The pipeline 2 is equipped with a track 5 for the passage of maglev trains. A safety step 6 connecting the track 5 and the pipeline 2 to the safety doors 4 is provided. The safety step 6 is longitudinally installed inside the pipeline 2. An inflatable slide 3 is provided in correspondence with each safety door 4. The inflatable slide 3 is stored on the side wall of the pipeline 2. When the safety door 4 is opened, the inflatable slide 3 can be unfolded to form an inflatable slide for people to slide down. The top of the inflatable slide is fixedly connected to the side wall of the pipeline 2, and the bottom is located on the side ditch platform 13.
[0041] In this embodiment, the inflatable slide 3 is typically in a folded, stowed state. On one hand, it can be stowed on the outside of the side wall of the pipe 2. After opening the safety door 4, the stowing device of the inflatable slide 3 can be opened, allowing the folded inflatable slide 3 to quickly inflate and form an inflatable slide. On the other hand, it can also be stowed inside the slide compartment on the side wall of the pipe 2 corresponding to the safety door 4, tightly connected to the safety door 4. Opening the safety door 4 triggers the inflatable slide 3 to slide down from the slide compartment and unfold, forming an inflatable slide for passengers to slide down. It is worth noting that in this application, the longitudinal direction refers to the front-to-back direction of the track 5, and the transverse direction refers to the left-to-right direction of the track 5.
[0042] The specific process of forming a rescue channel in the pipeline-type superconducting maglev track system of this utility model is as follows: In the event of an emergency in the maglev train or track 5, the maglev train brakes suddenly at a certain point in the pipeline 2. First, all the doors of the maglev train are opened. After exiting the maglev train, passengers can walk along the safety step 6 to the nearest safety door 4. Then, the safety door 4 is opened and the inflatable slide 3 is deployed to form an inflatable slide with its top on the side wall of the pipeline and its bottom on the side ditch platform 13. This forms a rescue channel of maglev train - safety step 6 - safety door 4 - inflatable slide 3 - side ditch platform 13, allowing passengers and staff on the maglev train to quickly evacuate to the side ditch platform 13 in emergency situations. This solves the rescue problem when a closed superconducting maglev track malfunctions.
[0043] Preferably, the track 5 has a U-shaped cross-section, and the safety pedal 6 is set between the top of the U-shaped track and the pipe 2. The top surface of the safety pedal 6 is preferably flush with the bottom surface of the safety door 4 to facilitate smooth passage of personnel.
[0044] Preferably, the distance between two adjacent safety doors 4 does not exceed the length of the maglev train. In this embodiment, when the maglev train is braked at any position on the pipe 2, there is at least one safety door 4 facing the maglev train, so that a rescue channel can be quickly formed along the safety door 4, eliminating the need to search for a nearby safety door 4 and saving time for rescue and evacuation.
[0045] More preferably, the pallet 12 has platforms extending beyond the rail beam 11 on both sides of the transverse direction, serving as a rescue platform to facilitate rescue operations by rescue personnel or equipment.
[0046] Preferably, the roadbed structure 1 includes a drainage ditch 16, which is disposed between the support plate 12 and the side ditch platform 13, so that the inflatable slide directly crosses the drainage ditch 16.
[0047] Preferably, the roadbed structure 1 is also provided with slope grass 7 on both sides in the transverse direction. The bottom of the slope grass 7 is connected to the side ditch platform 13. The slope grass 7 provides a buffer for people sliding down the inflatable slide.
[0048] In a preferred embodiment, the pipeline 2 is entirely assembled from lightweight concrete segments. On the one hand, lightweight concrete segments contain many closed pores, which can absorb noise and reduce noise pollution from the maglev train to the surrounding environment. On the other hand, lightweight concrete segments are lightweight, making them easy to hoist and install, and they also exert less pressure on the roadbed structure 1, thus reducing the vertical load on the roadbed structure 1.
[0049] In another preferred embodiment, the pipe 2 consists of an upper part and a lower part. The upper part is assembled from lightweight concrete segments, and the lower part is assembled from reinforced concrete segments. Alternatively, the lower part can be integrally cast with the track-supporting beam 11. In this embodiment, the pipe 2 is divided into upper and lower parts and constructed using different materials, so that the upper part serves as a sound barrier, while the lower part has greater strength to support the track 5 and the maglev train. Furthermore, the safety door 4 is preferably located in the upper part of the pipe 2, with its bottom flush with the lower part of the pipe 2. The top of the inflatable slide 3 is fixed to the side wall of the lower part of the pipe 2.
[0050] Preferably, the upper part can also be made of other lightweight sound insulation materials, such as polystyrene foam, gypsum, etc.
[0051] More preferably, the rail support beam 11 is composed of multiple rail support beam segments, with the segmentation points of the rail support beam 11 located in the middle of the support plate 12, meaning that the ends of each rail support beam segment are supported by the support plate 12. The distance between two adjacent support plates 12 is preferably not less than 5 meters to reduce the cost of large-scale foundation treatment, and at the same time, it eliminates the need for roadbed ballast filling, greatly reducing the cost of roadbed filling materials.
[0052] Preferably, multiple adjustable supports 14 arranged in a rectangular array are provided between each pallet 12 and the rail beam 11. When the maglev train is running, the dynamic load generated by the operation is transmitted to the adjustable supports 14 through the rail beam 11. The adjustable supports 14 undergo rotational deformation or translational deformation, thereby realizing deformation adjustment.
[0053] Specifically, the adjustable support 14 can be a movable support or a spherical steel support, or other types of support, as long as it meets the requirements for adjusting deformation.
[0054] Preferably, multiple piles 15 arranged in a rectangular array are provided below each support plate 12, so that the load is transferred to the support plate 12 through the adjustable support 14 under the rail beam 11, and then transferred from the support plate 12 to the piles 15, thereby improving the rigidity of the roadbed structure 1 to meet the stability requirements of superconducting maglev under ultra-high-speed operation. Preferably, the adjustable support 14 is located directly above the piles 15.
[0055] Preferably, the longitudinal spacing between two adjacent piles is greater than or equal to 5m; the net distance between the pile 15 and the boundary of the support plate 12 is not less than 0.5 times the pile diameter.
[0056] Preferably, the rail support beam 11, the support plate 12, and the foundation pile 15 are all reinforced concrete structures.
[0057] In a preferred embodiment, each pallet 12 is provided with eight adjustable supports 14 and eight foundation piles 15, which are evenly distributed below the left and right tracks. Specifically, four adjustable supports 14 and four foundation piles 15 are arranged in a rectangular array below the left track, and the other four adjustable supports 14 and four foundation piles 15 are arranged in a rectangular array below the right track. When the left and right tracks share a single rail support beam 11, one pallet 12 supports the ends of two rail support beam segments, and the end of each rail support beam segment is supported by four adjustable supports 14, the pallet 12, and four foundation piles 15. When the left and right tracks each use two rail support beams 11, such as... Figure 1 As shown, one support plate 12 is used to support the ends of four rail beam segments. The end of each rail beam segment is supported by two adjustable supports 14, the support plate 12, and two foundation piles 15, as follows. Figure 3 As shown. Preferably, the lateral / longitudinal spacing between adjacent foundation piles 15 is 5m, and the lateral / longitudinal spacing between adjacent adjustable supports 14 is also 5m.
[0058] In actual construction, this utility model also provides a construction method for a pipeline-type superconducting maglev track system, including the following process:
[0059] (1) Prefabrication stage of components: Prefabricate rail beam segments and lightweight concrete segments in the prefabrication plant;
[0060] (2) Site preparation stage: Clear the site, construct slope protection, excavate the roadbed to the design elevation; construct foundation piles, and construct the support plate after confirming that the pile body is qualified.
[0061] (3) On-site assembly and hoisting stage: transport the rail beam section to the site and hoist the rail beam section; assemble the lower half of the pipeline and hoist the rail; assemble the upper half of the pipeline, and at the same time construct the safety pedal and safety door and install the inflatable slide.
[0062] In this construction method, the prefabrication stage of components and the site preparation stage can be carried out simultaneously, and the on-site assembly stage can be carried out after both are completed.
[0063] This utility model discloses a pipeline-type superconducting maglev track system with a rescue passage, comprising a roadbed structure 1, a pipeline 2, and an inflatable slide 3. The roadbed structure includes a rail-bearing beam supporting the pipeline and longitudinally spaced support plates below the rail-bearing beam. Side ditch platforms are provided on both sides of the support plates. Multiple safety doors are longitudinally spaced on the side of the pipeline near the side ditch platforms. A longitudinally extending safety step is provided between the pipeline and the inner track, and the safety step connects to the safety doors. An inflatable slide is provided on the side wall of the pipeline corresponding to each safety door. When the safety door is opened, the inflatable slide can be unfolded to form an inflatable slide for personnel to slide down. The top of the inflatable slide is fixedly connected to the side wall of the pipeline, and the bottom is located on the side ditch platform, ultimately forming a rescue passage of maglev train-safety step-safety door-inflatable slide-side ditch platform, which meets the needs of personnel evacuation under emergency conditions and solves the rescue problem when a closed superconducting maglev track malfunctions.
[0064] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
