Fig. 1 shows a schematic structural diagram of a high-speed magnetic suspension traffic turnout system according to an embodiment of the invention.
As shown in fig. 1, the embodiment of the present invention provides a high-speed maglev traffic turnout system, wherein the system comprises a forward track 1, a lateral track 2, a forward track coil 3 disposed on the forward track 1, and a lateral track coil 4 disposed on the lateral track 2, the bottom of the forward track 1 is further provided with an opening 9, so that the lateral track 2 passes through the opening 9 (for example, passes through the opening downwards or upwards), when a vehicle (for example, a high-speed maglev train) needs to pass forward, only the forward track coil 3 is communicated to provide a levitation force and a guiding force for the vehicle on the forward track 1, and when the vehicle needs to pass laterally, only the lateral track coil 4 is communicated to provide a levitation force and a guiding force for the vehicle on the lateral track 2.
Through the technical scheme, the turnout system can be respectively provided with the forward track and the lateral track, the bottom of the forward track is further provided with the opening so that the lateral track penetrates out of the opening, when a vehicle needs to pass in the forward direction, only the forward track coil is communicated to provide the suspension force and the guiding force for the vehicle on the forward track, so that the vehicle enters the forward track, and when the vehicle needs to pass in the lateral direction, only the lateral track coil is communicated to provide the suspension force and the guiding force for the vehicle on the lateral track, so that the vehicle enters the lateral track. Therefore, the efficiency problem caused by the fact that the traditional turnout needs to be moved back and forth is avoided, and the electromagnetic switching can ensure that the vehicle can be quickly and stably switched into a rail; meanwhile, the integral structure without moving enhances the integral rigidity of the turnout, and avoids the turnout resonance problem of the traditional turnout
For example, for a vehicle (for example, a direct vehicle) which needs to cross the station and pass without stopping at the intermediate station, the vehicle needs to pass at a high speed in the forward direction, at the moment, coils of the forward track are connected (communicated), only the forward track has suspension force and guiding force, the suspension force can be ensured to be stable at a high speed, the speed is not required to be accurately controlled, and the problem of insufficient suspension force caused by too low speed can be avoided. For the vehicles needing to be decelerated in advance and stopped at the intermediate station, the vehicles need to pass in the lateral direction, the forward track coil is disconnected, the lateral track coil is communicated, and the vehicles run into the lateral track by virtue of the suspension force and the guiding force provided by the coils. In addition, when the vehicle breaks down and runs at a low holding speed, the vehicle can also drive into the lateral track, and then enters an auxiliary parking interval to wait for rescue and maintenance.
Therefore, the road gate system can realize the rapid and stable rail transfer of the vehicle (namely, the direct vehicle continuously moves forwards at high speed through the cross-station turnout of the middle station in the forward direction, and the stop vehicle enters the station through the cross-station turnout in the lateral direction to stop), and the maximization of the transportation capacity of the whole line and the flexibility and the safety of the driving organization are ensured.
Further, as shown in fig. 1, the forward rail 1 may be supported by the pier 6, and the lateral rail 2 may be supported by the connecting pier 7.
Fig. 2 shows a schematic cross-sectional view of a forward rail according to an embodiment of the invention.

According to an embodiment of the present invention, as shown in fig. 2, the system further comprises a movable floor 5 which is provided on the bottom lower surface of the forward track 1 and can move back and forth, wherein the movable floor 5 is moved in advance to below the opening when the vehicle is passing in the forward direction, and the movable floor is moved away from below the opening when the vehicle is passing in the lateral direction.
Through set up the removal bottom plate that can move back and forth on positive track, when the vehicle need forward current, the bottom plate removes in advance to positive track opening (vacancy) department as filling, prevents to drop from the vacancy when the suspension force is not enough because of superconducting magnet quench leads to, further ensures vehicle operation safety. And when the vehicle passes laterally, the movable bottom plate is moved away from the lower part of the opening in advance so that the vehicle can drive into the lateral track through the opening.
According to an embodiment of the present invention, as shown in fig. 2, the system further comprises a moving wheel 8, and the moving base plate 5 moves back and forth on the bottom lower surface of the forward rail 1 by the moving wheel 8.
Alternatively, according to an embodiment of the present invention, the system may further include a moving slide, by which the moving base plate 5 moves back and forth on the bottom lower surface of the forward rail 1.
That is, the moving wheel and the moving rail may alternatively be used to realize the forward and backward movement of the moving base plate on the lower surface of the bottom of the forward rail.
Fig. 3A and 3B are schematic diagrams illustrating a bottom moving floor removal state and a closed state, respectively, of a forward track, according to an embodiment of the present invention.
Fig. 3A is a schematic diagram of a bottom moving floor moving-away state of the forward track, and fig. 3B is a schematic diagram of a bottom moving floor closing state of the forward track.
The moving bottom plate is moved away to ensure the lateral passing of the vehicle, and the closing of the moving bottom plate can further ensure the safety of the vehicle in high-speed running.
It will be understood by those skilled in the art that the above description of the moving wheels and moving tracks is merely exemplary and not intended to limit the present invention. Any other way of achieving sliding of the movable floor can be applied to the present invention.
According to an embodiment of the present invention, the forward track coil 3 and the lateral track coil 4 are 8-word coils.
It can be seen from the above embodiments that the barrier gate system described in the above embodiments of the present invention can ensure that the vehicle is quickly and stably derailed. When the vehicle passes on the forward track at a high speed in the forward direction, the high-speed stable running of the vehicle can be ensured. In addition, the movable moving bottom plate is arranged on the lower surface of the bottom of the forward track, so that the safety of the train in the forward track operation can be further ensured.
In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
