Description

Technical Field

[0001] The present application relates to the technical field of magnetic levitation tracks, and in particular to an upper and lower layered high-speed magnetic levitation turnout and platform. Background Art

[0002] High-speed maglev turnouts are important road structures for the line-changing operation of maglev trains. Their structure and state have a direct impact on the safety, stability and comfort of train operation as well as passengers. As one of the key technologies for superconducting electric high-speed maglev transportation, the independent innovation research of high-speed maglev turnout technology can provide an important reference for the construction of my country's high-speed maglev lines. High-speed turnouts have a complex structure, involving multiple professional interfaces such as mechanics, electrical, and control, and are technically difficult, which is significantly different from traditional wheel-rail railway turnouts.

[0003] In the related technology, high-speed turnouts use elastic bendable beams or variable curvature segmented beams to bend the straight turnout track toward the side rail and dock with the side rail, so that the train switches to the straight side rail. Usually, a turnout section is about 150 meters long. The turnout is bent transversely to achieve line change. Its mechanical and electrical structure is extremely complex. The turnout is bent transversely, which reduces the structural strength and makes the straight strand passing speed of the turnout lower than the main line passing speed, resulting in a straight strand passing speed of no more than 500km / h. The cost of a single set of turnouts is about 40 million yuan. A single standard station requires at least four sets of turnouts. The cost of the turnout alone is as high as 160 million yuan. In addition, the structural maintenance of the turnout to achieve line change by bending transversely occupies a large area. The complexity of the structure leads to inconvenience in operation and maintenance. The high cost makes it difficult to popularize maglev stations, which seriously hinders the development of high-speed maglev transportation. Summary of the invention

[0004] In order to improve the high cost problem of high-speed maglev stations, the present application provides an upper and lower layered high-speed maglev turnout and platform.

[0005] The application provides a high-speed maglev turnout with upper and lower layers, which adopts the following technical solution: An upper and lower layered high-speed maglev turnout, comprising: Main line guide rail, including main line coil and main line running rail; A turnout foundation, comprising a top plate and a plurality of columns arranged below the top plate; A straight strand guide rail comprises a straight strand coil and a straight strand running rail, wherein the straight strand running rail is slidably arranged above the top plate between a use state and an avoidance state, wherein the straight strand running rail is connected with the main line running rail when in the use state, and the straight strand running rail is staggered with the main line running rail when in the avoidance state; A side strand guide rail is provided below the top plate, and comprises a side strand coil and a side strand running rail, wherein the side strand running rail is a smooth arc-shaped rail having one end connected to the main line running rail; and A switch machine, arranged on the top plate and used to drive the straight running rail to slide; The top plate is provided with an avoidance gap for the train to travel from the main line running rail to the side track running rail.

[0006] Furthermore, the straight strand running rail includes a straight strand point rail and a straight strand basic rail, the straight strand point rail is located on the side of the straight strand basic rail close to the mainline running rail, the bottom of the straight strand point rail is fitted with the top surface of the side strand running rail, and the top is flush with the mainline running rail.

[0007] Furthermore, the straight strand coil includes a plurality of straight strand traction coils and a plurality of straight strand suspension coils, and the side strand coil includes a plurality of straight strand traction coils.

[0008] Furthermore, the base is provided with a straight track plate, and two groups of the straight track plates are symmetrically arranged on both sides of the straight running rails, and the straight track plates are provided with installation grooves for installing straight coils.

[0009] Furthermore, a groove is provided at the bottom of the straight track plate. When in an avoidance state, the straight running rail is received in the groove, and the side surface of the straight running rail is flush with the side surface of the straight coil.

[0010] Furthermore, the switch machines are provided in plurality, and the plurality of switch machines are arranged at intervals along the length direction of the top plate, and the pull rods of the switch machines pass through the straight track plate and are connected to the straight running rails.

[0011] Furthermore, two side walls are provided below the bottom plate, the side strand guide rail is located between the two side walls, and the side strand coil and the side strand guide rail are both provided on the side walls.

[0012] Furthermore, the side track includes a first curved rail and a second curved rail, and the first curved rail and the second curved rail are circular arc rails arranged on opposite sides of the center of a circle tangent to each other, and one end of the first curved rail and the second curved rail are tangent to the main line track, and the end of the second curved rail away from the first curved rail is tangent to the horizontal plane.

[0013] The present application also provides an upper and lower layered high-speed maglev platform, including an upper guide rail, a lower guide rail and a lower platform located between two symmetrically arranged groups of turnouts, the upper guide rail includes an upper coil and an upper running rail, the lower guide rail includes a lower coil and a lower running rail, the two ends of the upper running rail are respectively connected to two groups of straight guide rails, the two ends of the lower guide rail are respectively connected to two side running rails and are tangent to each other, and the lower platform is located on one side of the lower guide rail.

[0014] Furthermore, it also includes an upper platform, which is located on one side of the upper guide rail.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application adopts the design of the turnout structure of the upper and lower layers. When the train needs to stop at the station, it slows down in advance so that the train runs along the mainline running rail. The straight running rail is controlled to slide by the switch machine so that it is misaligned with the mainline running rail. When the train reaches the turnout, it moves forward along the side running rail, enters the lower layer and stops, which is convenient for passengers to get on and off. Compared with the turnout beam structure with transverse bending and deformation, the turnout structure of the present application is simple, easy to control, shorter in length, with a small mass of the switch part and a short moving distance. The upper and lower layer distribution method can reduce the footprint of the turnout structure, and the simple switching line structure can greatly reduce the turnout manufacturing and construction costs; 2. The structural strength of the straight rail of the present application is not lower than that of the main line rail. In the turnout structure with transverse bending and deformation, since the turnout rail needs to have bending and deformation capabilities, its strength is lower than that of the main line rail, and the train needs to slow down when passing through. The turnout of the present application does not need to slow down when the train passes through the straight rail, and the speed can reach 600km / h; 3. When the train passes along the straight track at high speed, the straight track does not bear the load, which reduces the maintenance workload and the maintenance cost of the turnout; 4. The main line of the platform of this application can also be used as the station line for passengers to get on and off, and after a train stops along the side track, another train can pass at high speed along the straight track without interfering with each other, thus improving traffic efficiency; 5. The double-deck turnout of this application can be equipped with a single-deck platform or a double-deck platform according to the station requirements, solving the problem that traditional platforms need to set up independent platforms. The platform of this application can be designed as an integrated whole with the station hall, reducing the station area and simplifying the boarding process; 6. The double-deck turnout design of this application realizes physical isolation between the main line and the station line, reduces the impact of aerodynamics and noise on passengers, and improves riding comfort.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present application embodiment discloses a high-speed maglev turnout with upper and lower layers. Figure 1The upper and lower layered high-speed maglev turnout includes a mainline guide rail 1, a turnout foundation 2, a straight guide rail 3, a side guide rail 4 and a switch machine 5. The present application uses the characteristics of the maglev vehicle running close to the ground at a low speed (not more than 120km / h) and floating at a high speed to set a running rail with a special structure at the turnout to realize the vehicle switching, so that the train can pass at a high speed or stop at the station when passing through.

[0030] Among them, the main line guide rail 1 includes a main line coil 11 and a main line running rail 12, the main line running coil includes a main line traction coil and a main line suspension coil, and the main line running rail 12 is cast with concrete. The detailed structure can refer to the patent application with application number CN202410993974.8.

[0031] The turnout foundation 2 is connected to the main line foundation of the main line guide rail 1, and includes a top plate 21 and a plurality of columns 22 arranged on the top plate 21. The plurality of columns 22 are symmetrically arranged on both sides of the bottom of the top plate 21 in two groups. Figure 1 and Figure 2 As shown, the top plate 21 and the columns 22 are both cast by concrete.

[0032] The straight strand guide rail 3 includes a straight strand coil 32, a straight strand running rail 31 and a straight strand guide rail 33. Since the straight strand guide rail 3 needs to meet both high-speed passage and traction function to achieve the stop requirement, the straight strand coil 32 includes a plurality of straight strand traction coils and a plurality of straight strand suspension coils arranged in a straight line. The straight strand running rail 31 is slidably arranged on the top plate 21 in the transverse direction (perpendicular to the travel direction of the train), and between the use state and the avoidance state, when in the storage state, the straight strand running rail 31 is in collinear communication with the mainline running rail 12, and when in the avoidance state, the straight strand running rail 31 is staggered with the mainline running rail 12; the straight strand guide rail 33 is located above the straight strand coil, and the straight strand guide rail 33 is arranged on both sides of the straight strand running rail 31 and is used to guide the passing vehicle in the transverse direction. Guide wheels are arranged on the side of the suspension train, and the straight strand guide rail 33 cooperates with the guide wheels on the side of the train to guide the train in the transverse direction.

[0033] The side strand guide rail 4 is located below the top plate 21. The side strand guide rail 4 includes a side strand coil 42, a side strand running rail 41 and a side strand guide 43. Since the purpose of the train entering the side strand guide rail 4 is to stop and get on and off passengers, the train does not need to travel in suspension on the side strand guide rail 4, but only needs to travel at a low speed and stop. Therefore, the side strand coil 42 only includes a plurality of traction coils arranged in a straight line, and no suspension coil is required. The side strand running rail 41 is a smooth arc track, and one end is tangentially connected to the main line running rail 12, and the other end is connected to the station line track. The side strand running rail 41 is connected to the side strand track 43 by a The side strand foundation support is made of concrete; an avoidance gap is opened on the top plate 21 for the train to travel from the main line running track 12 to the side strand running track 41. When the train needs to stop at the station, it first reduces the speed to less than 120km / h, and the train enters the turnout along the main line running track 12, and enters the station along the side strand running track 41 through the avoidance gap. The side strand coil 42 plays the role of braking and starting the train; the trajectory of the side strand guide rail 43 is the contoured arc of the side strand running track 41, and its structural principle is the same as that of the straight strand guide rail 33. For details, please refer to Figure 6 shown.

[0034] The straight track running rail 31, the main line running rail 12 and the side track running rail 41 are all tracks with a rectangular cross section made of concrete.

[0035] The switch machine 5 is arranged on the top plate 21, and is used to drive the straight running rail 31 to slide between the use state and the avoidance state.

[0036] When the train passes a station without stopping, the main line suspension coil and the straight strand suspension coil are used to drive the train to suspend and travel, and during this process, the switch machine 5 controls the straight strand running rail 31 to connect with the main line running rail 12. The straight strand running rail 31 protects the train at the bottom of the high-speed train, and can receive the train that falls due to line faults, reducing the possibility of serious damage to the train due to line faults; when the train needs to stop at a station, it slows down in advance, so that the running wheels at the bottom of the train move forward along the main line running rail 12, and the switch machine 5 controls the straight strand running rail 31 to stagger with the main line running rail 12, so that the train enters the side strand running rail 41 along the straight strand running rail 31 and arrives at the platform to stop. The upper and lower layered turnout design does not require a complex horizontal line curve deformation structure, has a simplified structure, is easy to control, occupies a small area, and can greatly reduce the turnout manufacturing and construction costs.

[0037] When one train stops at the lower level, another train can pass through the station at the upper level along the straight guide rail 3 at high speed, which can greatly improve the traffic efficiency. Passengers getting on and off the lower level are physically isolated from the high-speed train on the upper level, reducing the airflow disturbance and noise caused by the high-speed train passing by when getting on and off, thereby improving the passenger comfort.

[0038] As an alternative embodiment, the side strand guide rail 4 may also be arranged above the straight strand guide rail 3. This embodiment may be used for special station requirements of passengers boarding and alighting at the upper level and getting off and passing through at high speed.

[0039] Specifically, refer to Figure 2 and Figure 3 , a straight track plate 23 is provided on the turnout foundation 2. The straight track plate 23 is cast in concrete and fixedly connected to the top plate 21 by bolts, nuts and other fasteners. There are two groups of straight track plates 23, which are symmetrically arranged on both sides of the straight running rail 31. A guide surface 233, a mounting groove 232 and a groove 231 are provided on the side of the straight track plate 23 close to the straight running rail 31. The guide surface 233 is the top of the straight track plate 23 and is used to cooperate with the guide wheel on the side of the train. The mounting groove 232 is used to install the straight coil 32, and the straight coil 32 after installation is flush with the guide surface 233. The groove 231 is provided at the bottom of the straight track plate 23 to accommodate the straight running rail 31, so that the straight running rail 31 can be completely received in the groove 231 when it is in the avoidance state.

[0040] In order to improve the stability of the turnout foundation 2, the turnout foundation 2 is provided with two side walls 24 on both sides of the side strand guide rails 4. The two side walls 24 are cast integrally with the top plate 21, and the two sides of the side strand foundation are respectively abutted against the two side walls 24, so that the side walls 24 can support the side strand guide rails 4.

[0041] The straight track plate 23 is similar to the track plate structure of the main track, so that the structural strength of the straight track guide rail 3 is not lower than that of the main track guide rail 1. When the train passes at high speed, there is no need to slow down, so that the train can pass the station at a speed of 600km / h. In the prior art, the lateral bending deformation turnout structure, such as the Japanese lateral articulated turnout, has a straight track passing speed limit of 500km / h. The turnout in the embodiment of the present application has a higher upper limit on the high-speed passing speed of the train.

[0042] In order to achieve non-interference between the straight strand running rail 31 and the side strand running rail 41, the straight strand running rail 31 includes an integrally formed straight strand point rail 311 and a straight strand basic rail. The straight strand point rail 311 is located on the side of the straight strand basic rail close to the mainline running rail 12. The bottom of the straight strand running rail 31 is an arc shape that is in contact with the top surface of the side strand running rail 41, and the top is flush with the mainline running rail 12. The specific shape is as follows: Figure 5 and Figure 7 shown.

[0043] The side track 41 includes a first curved rail and a second curved rail. The first curved rail and the second curved rail are arc-shaped rails arranged on opposite sides of the center of a circle that are tangent to each other. One end of the first curved rail is tangent to the main line track 12 to facilitate the smooth entry of the train into the side track 41. The end of the second curved rail away from the first curved rail is tangent to the horizontal plane to facilitate connection with the station line.

[0044] refer to Figure 3 and Figure 8 In order to facilitate the lateral sliding of the straight strand running rail 31, the straight strand running rail 31 adopts a cantilever structure design. A plurality of cross beams 34 are provided on the side of the straight strand running rail 31 close to the switch machine 5. The plurality of cross beams 34 are arranged at equal intervals along the length direction of the straight strand running rail 31. The end of the cross beam 34 away from the straight strand running rail 31 passes through the straight strand track plate 23 and is slidably arranged. The switch machine 5 is provided with a plurality of and all are fixed on the top plate 21. The pull rod 51 of the switch machine 5 passes through the straight strand track plate 23 and is fixedly connected to the straight strand running rail 31. When in use, the bottom of the straight strand point rail 311 of the straight strand running rail 31 is supported on the side strand running rail 41, and the straight strand base rail 312 is suspended on one side of the straight strand track plate 23 through a plurality of cross beams 34.

[0045] The present application also discloses a vertically layered high-speed maglev platform. Figure 5 and Fig. 9 The upper and lower layered high-speed maglev platform includes an upper guide rail 6, a lower guide rail 7 and a lower platform 8 arranged between two sets of turnouts, and the two sets of turnouts are symmetrically arranged. The upper guide rail 6 includes an upper coil 62 and an upper running rail 61, and its structure is the same as that of the main line guide rail 1. The two ends of the upper running rail 61 are respectively connected to the straight strand running rails 31 of the two sets of turnouts in a colinear manner. The lower guide rail 7 includes a lower coil 72 and a lower running rail 71. Compared with the main line guide rail 1, the lower coil 72 only includes a traction coil but not a suspension coil, which can reduce the cost. The lower running rail 71 is tangent to and connected with the end of the side track 41 away from the main line running rail 12. The lower platform 8 is arranged on one side of the lower running rail 71. The lower platform 8 is an integrated design of the platform and the station hall, and is provided with a plurality of lower gates 81. After the train runs from the side track 41 to the lower running rail 71 and stops, the doors of the train correspond to the positions of the lower gates 81. Passengers can get on and off the train by waiting in front of the lower gates 81 for opening. Please refer to the subway riding method.

[0046] Through the upper and lower layered turnout design, the station hall and platform are integrated, independent platforms are eliminated, the station's floor space is further reduced, and the boarding process is simplified.

[0047] In this embodiment, the upper level of the station is only used for passing trains, and the lower level is used for stopping and getting on and off passengers. As an alternative embodiment, an upper platform 9 is provided on one side of the upper running track 61, such as Fig.10 When the train needs to stop at the upper platform 9, it slows down in advance, switches from the suspended state to the running state, and runs along the upper running rail 61 and the straight running rail 31 in use state at a low speed along the straight running rail 31 to the upper running rail 61 and stops. Fig.10The upper platform 9 is integrated with the station hall and is provided with a plurality of upper gates 91. After the train runs from the straight track 31 to the upper track 61 and stops, the train doors correspond to the positions of the upper gates 91. Passengers can get on and off the train by waiting in front of the upper gates 91 for the gates to open.

[0048] According to the passenger flow environment of the station, choosing to set up a single-layer platform or a double-layer platform can better control the cost of the platform, and when the upper gate 91 is closed, it does not affect the high-speed traffic of the upper guide rail 6, which can ensure the efficient traffic of the station.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
