Description

Technical Field

[0001] This invention belongs to the field of maglev rail transit technology, specifically relating to a low-speed turnout for a superconducting electric maglev railway. Background Technology

[0002] Superconducting electric maglev trains are high-speed trains that utilize superconducting magnetic levitation technology and electric drive technology. By using superconducting magnetic levitation technology to levitate the train above the track, it eliminates the frictional resistance of traditional rail trains, thus enabling higher operating speeds and lower energy consumption. Superconducting electric maglev trains have advantages such as high speed, low energy consumption, environmental friendliness, and high safety, and are considered an important development direction for future intercity high-speed transportation. With continuous technological advancements and cost reductions, superconducting electric maglev trains are expected to become one of the main modes of transportation for intercity high-speed travel in the future.

[0003] Low-speed turnouts on superconducting electric maglev railways are fundamental equipment for trains to switch tracks in large passenger stations and depots. Their structure and condition directly affect the safety, stability, and passenger comfort of train operation. Due to the large number of low-speed turnouts, their construction cost directly affects the construction cost of passenger stations.

[0004] The length of sidewall-moving turnouts in related technologies is usually over 60m. The switching action of the turnout segments includes planar movement, vertical movement, and planar rotation. The turnout switching structure is diverse and complex, and a dedicated mechanical room for mechanical devices needs to be set up separately under the turnout. Although it can realize the switching of the turnout, the above-mentioned sidewall-moving turnout structure is relatively complex and has high construction and maintenance costs, which will lead to a significant increase in the construction difficulty and construction cost of large passenger stations for high-speed maglev trains.

[0042] Example:

[0043] Please see Figures 1-5 The superconducting electric maglev railway low-speed track in the preferred embodiment of the present invention can not only realize stable low-speed track switching of superconducting maglev vehicles, but also reduce the land area occupied by the turnout while simplifying the turnout structure, thereby reducing the construction cost of the turnout structure and significantly improving the convenience of operation and maintenance of the turnout structure.

[0044] Specifically, in a preferred embodiment of this application, the superconducting electric maglev railway low-speed turnout is located between the mainline track 1 before the turnout and the straight track 2 and the side track 3 after the turnout, which intersect at the end, to facilitate connection between the mainline track 1 before the turnout and the straight track 2 after the turnout, or between the mainline track 1 before the turnout and the side track 3 after the turnout. The superconducting electric maglev railway low-speed turnout includes a turnout area base plate 8 and a movable guide mechanism.

[0045] The top surface of the base plate 8 in the turnout area is flush with the top surface of the running plate 20 of the main line track 1 before the turnout, the straight track 2 after the turnout, and the side track 3 after the turnout, forming a continuous running surface between the main line track 1 before the turnout, the straight track 2 after the turnout, and the side track 3 after the turnout. Simultaneously, a straight track guide rail 9 and a side track guide rail 10 are respectively provided on both sides of the base plate 8 in the turnout area. One end of the straight track guide rail 9 is connected to the straight track slab 5 outside the straight track 2 after the turnout, and the other end of the straight track guide rail 9 is connected to the main line track slab 4 of the main line track 1 before the turnout, which is closer to the straight track slab 5 after the turnout. This forms a continuous guide surface 21 between the main line track slab 4 before the turnout and the straight track slab 5 after the turnout, providing stable guiding support for the guide wheels on the outside of the maglev vehicle when the turnout connects the main line track 1 before the turnout and the straight track 2 after the turnout.

[0046] Furthermore, one end of the side guide rail 10 is connected to the side track plate 6 on the outside of the side track 3 behind the turnout, while the other end of the side guide rail 10 is connected to the main track plate 4 on the front track 1 near the side track plate 6 behind the turnout. This is to form a continuous guide surface 21 between the main track plate 4 before the turnout and the side track plate 6 behind the turnout, so as to provide stable guiding support for the guide wheel on the outside of the maglev vehicle when the turnout connects the main track 1 before the turnout and the side track 3 behind the turnout.

[0047] More preferably, the movable guide mechanism includes a movable point rail 15, at least two guide components, and at least two point rail drive components. The end of the movable point rail 15 is connected to a guide rail 7 located at the intersection of the straight track 2 and the side track 3 after the turnout. Simultaneously, the guide components are arranged longitudinally at intervals on the turnout area base plate 8, and each guide component includes a point rail column 16 and a point rail groove 17. The groove 17 is disposed on the turnout area base plate 8, and the bottom end of the point rail column 16 is slidably disposed in the groove 17, while the top end of the column 16 is fixedly connected to the movable point rail 15. Both lateral sides of each point rail column 16 are connected to the moving end of at least one point rail drive component, used to drive the point rail column 16 to slide back and forth in the groove 17, thereby driving the end of the movable point rail 15 away from the guide rail 7 to sequentially connect to two front mainline track plates 4.

[0048] It is worth noting that, in the preferred embodiment of this application, the extension direction of the main track 1 before the fork and the straight track 2 after the fork is longitudinal, and the direction perpendicular to the longitudinal direction in the horizontal plane is transverse, that is, the width direction of the main track 1 before the fork and the straight track 2 after the fork, and the direction perpendicular to or vertical to the horizontal plane is vertical.

[0049] Furthermore, in a preferred embodiment of this application, a plurality of longitudinally spaced support columns 11 are provided at the bottom of both the straight guide rail 9 and the side guide rail 10. The bottom of the support column 11 is provided on the base plate 8 of the branch area, which is used to support the straight guide rail 9 and the side guide rail 10 to the height of the maglev vehicle guide rail, so that the straight guide rail 9 and the side guide rail 10 can form a stable guide with the maglev vehicle guide rail.

[0050] Further preferably, in the preferred embodiment of this application, the portion of the guide rail 9 near the main line track 1 before the turnout is a movable guide rail 12 that can reciprocate laterally, and correspondingly, the portion of the guide rail 10 facing the main line track 1 before the turnout is a movable guide rail 13 that can reciprocate laterally.

[0051] In actual use, when a vehicle passes straight ahead, the turnout is in a straight-through state, connecting the mainline track 1 before the turnout and the straight track 2 after the turnout. The movable guide rail 12 of the straight track moves inward, allowing the guide rail 9 of the straight track to connect with the mainline track slab 4 before the turnout. At the same time, the movable guide rail 13 of the side track moves outward, disengaging it from the mainline track slab 4 before the turnout. Then, the movable center rail 15 is driven to move, connecting the mainline track slab 4 before the turnout and the guide rail 7 of the turnout to the side of the movable guide rail 13 of the side track corresponding to the movable guide rail 13 of the side track before the turnout.

[0052] When a vehicle changes tracks, the turnout is in the track-changing state, connecting the main line track 1 before the turnout and the side track 3 after the turnout. The movable guide rail 13 of the side track moves inward, allowing the side guide rail 10 to connect with the main line track slab 4 before the turnout. Simultaneously, the movable guide rail 12 of the straight track moves outward, disengaging it from the main line track slab 4 before the turnout. Then, the movable point rail 15 is driven to move, connecting the main line track slab 4 before the turnout and the guide rail 7 after the turnout on the side of the movable guide rail 12 of the straight track corresponding to the main line track 1 before the turnout.

[0053] More specifically, in a preferred embodiment of this application, at least one guiding drive component is provided between the straight movable guide rail 12 and the side movable guide rail 13 and the switch area base plate 8, respectively. This guiding drive component includes a guide rail groove 14 and a switch machine 19 formed on the switch area base plate 8. Furthermore, a support column 11 is provided below both the straight movable guide rail 12 and the side movable guide rail 13. The top end of the support column 11 is fixed to the bottom end face of the straight movable guide rail 12 or the bottom end face of the second movable guide rail. Simultaneously, the bottom end face of the support column 11 is slidably disposed in the guide rail groove 14 of the guide rail, thereby enabling both the straight movable guide rail 12 and the side movable guide rail 13 to reciprocate laterally. Further, both sides of the bottom end of the support column 11 are fixedly connected to the flexible cable of at least one switch machine 19, thereby driving the straight movable guide rail 12 or the side movable guide rail 13 to reciprocate laterally in the guide rail groove 14.

[0054] Furthermore, in a preferred embodiment of this application, the centerline of the main track 1 before the turnout and the centerline of the straight track 2 after the turnout are on the same straight line, and the centerline of the main track 1 before the turnout intersects with the centerline of the side track 3 after the turnout. When the maglev vehicle moves from the main track 1 before the turnout to the straight track 2 after the turnout, the maglev vehicle needs to move in a straight line on the turnout. Correspondingly, when the maglev vehicle moves from the main track 1 before the turnout to the side track 3 after the turnout, the maglev vehicle needs to move in an arc on the turnout. Therefore, the straight track guide rail 9 is a straight guide rail, and the side track guide rail 10 is an arc-shaped guide rail. Furthermore, the straight track movable guide rail 12 is a straight movable rail, and the side track movable guide rail 13 is a curved movable rail.

[0055] More preferably, in the preferred embodiment of this application, the radius of the side guide rail 10 is determined according to the speed at which the maglev vehicle passes through the turnout. More preferably, the turnout type is classified according to the speed at which the maglev vehicle passes through.

[0056] Furthermore, in a preferred embodiment of this application, the center rail groove 17 is an arc-shaped groove, and the central angle of each arc-shaped groove increases sequentially along the line connecting the guide rail 7 near the turnout to the line away from the guide rail 7, thereby enabling the center rail column 16 supporting the movable center rail 15 at each position to have sufficient lateral movement.

[0057] More preferably, in the preferred embodiment of this application, when the adjustable center rail is connected to the two front main line track plates 4 of the front main line track 1 respectively, its projection in the vertical direction intersects with the projection of each arc-shaped slide groove in the vertical direction, thereby enabling the drive component to drive the adjustable center rail to move in each arc-shaped slide groove, and thus enabling the adjustable center rail to flexibly connect to the two front main line track plates 4 on both sides of the front main line track 1 at the end away from the guide rail 7.

[0058] More specifically, in a preferred embodiment of this application, an arc-shaped vertical groove and an arc-shaped vertical surface are provided between the guide rail 7 and the adjustable center rail, so that the two sides of the guide rail 7 can respectively form continuous guide surfaces 21 with the two sides of the adjustable center rail. Preferably, the arc-shaped vertical surface is provided at the end of the guide rail 7, and the arc-shaped vertical groove is provided at the end of the adjustable center rail.

[0059] Furthermore, in a preferred embodiment of this application, the cross-section of the center rail groove 17 is T-shaped. Correspondingly, the bottom of the center rail column 16 is provided with a T-shaped slider that can be embedded in the center rail groove 17. Meanwhile, flexible cable mounting holes 18 are provided on both lateral sides of the T-shaped slider. The driving component is a switch machine 19. The moving end of the switch machine 19 is fixed to one end of the flexible cable, and the other end of the flexible cable is fixedly connected to the flexible cable mounting hole 18 on the T-shaped slider, so that the rotation of the moving end of the switch machine 19 can drive the center rail column 16 to move within the center rail groove 17.

[0060] Preferably, the sliding structure between the support column 11 and the guide rail groove 14, and the connection form of the switch machine 19 in the guide drive are similar to the above-described structures, and will not be described again here.

[0061] Further preferably, in a preferred embodiment of this application, the movable guide mechanism further includes a locking unit disposed between the center rail slide 17 and the center rail column 16, used to lock the relative position of the center rail column 16 and the center rail slide 17 after the center rail column 16 has moved into position. Preferably, the locking unit is an electromagnetic elastic pin disposed in the center rail slide 17. When the center rail column 16 slides relative to the center rail column 16, the electromagnetic elastic pin retracts into the mounting hole opened in the center rail slide 17. After the center rail column 16 completes its position movement, the electromagnetic elastic pin pops out from the mounting hole, thereby limiting the position of both sides of the center rail column 16.

[0062] Furthermore, in a preferred embodiment of this application, when the movable center rail 15 is connected to the rear side rail 3 of the connecting fork, the center rail drive assembly drives the movable center rail 15 to bend into an arc-shaped structure.

[0063] Furthermore, in a preferred embodiment of this application, the first guide side of the movable center rail 15 facing the straight guide rail 9 is a plane, and the second guide side of the movable center rail 15 facing the side guide rail 10 is an arc-shaped surface.

[0064] The superconducting electric maglev railway low-speed turnout of this invention has a simple structure, stable operation, and small space occupation. It adopts a turnout area foundation plate 8 between the main line track 1 before the turnout and the straight track 2 and the side track 3 after the turnout. The top surface of the turnout area foundation plate 8 is flush with the running plate 20 on the main line track 1 before the turnout, the straight track 2 after the turnout, and the side track 3 after the turnout. This allows the low-speed maglev vehicle to move stably from the main line track 1 before the turnout to the straight track 2 or the side track 3 after the turnout with the help of the running wheels set at the bottom of the car body. Meanwhile, by setting up a straight guide rail 9 and a curved side guide rail 10 on the base plate 8 of the turnout area, and combining a movable center rail 15 that can rotate around the rear guide rail 7, a center rail slide 17 set at the end of the center rail column 16, and a switch machine 19, the end of the movable center rail 15 away from the rear guide rail 7 can be connected to the front main line track plates 4 on both sides of the front main line track 1, so as to form a guide channel between the front main line track 1 and the rear straight track 2 or the front main line track 1 and the rear side track 3, thereby forming a guide rail for the guide wheels on both sides of the maglev vehicle, which has good prospects for promotion and application value.

[0065] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
