Description

Technical Field

[0001] This invention relates to the field of track structure technology, and more specifically, to a train track. Background Technology

[0002] With the development of rail train technology, conventional maglev trains and superconducting maglev trains have gradually acquired engineering capabilities and are being put into operational application.

[0003] However, due to the different operating principles and track types of conventional maglev trains, superconducting maglev trains, and wheel-rail trains, the applicable track structures are different, and the tracks of these three types of trains are very different and incompatible, posing a challenge to the train network.

[0004] To avoid impacting existing railway networks, how to achieve compatible tracks for three types of trains—wheel-rail trains, conventional maglev trains, and superconducting maglev trains—is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a train track that is compatible with wheel-rail trains, conventional maglev trains and superconducting maglev trains.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A train track, comprising:

[0008] The track body includes a horizontal part and a vertical part, wherein the vertical part is perpendicularly connected to the bottom middle position of the horizontal part;

[0009] Two parallel wheel rails are provided on the upper surface of the horizontal section;

[0010] The track for the superconducting maglev train is located on the upper surface of the horizontal section and between the two wheel rails;

[0011] The track for a conventional maglev train includes a levitation traction surface and a guide surface. The levitation traction surface is located on the lower surface of the horizontal section and on both sides of the vertical section, and the guide surface is located on both sides of the horizontal section.

[0012] Optionally, the track for the superconducting maglev train includes:

[0013] A U-shaped groove is provided on the upper surface of the horizontal part;

[0014] Superconducting magnets are disposed on both sides of the U-shaped groove.

[0015] Optionally, the U-shaped groove is located at the center of the horizontal portion.

[0016] Optionally, the center of the gauge of the two wheel rails coincides with the center of the track for the superconducting maglev train.

[0017] Optionally, the upper surface of the horizontal portion is provided with a groove, and at least a portion of the wheel rail is disposed within the groove.

[0018] Optionally, the upper surface of the wheel rail is flush with the upper surface of the horizontal portion.

[0019] Optionally, the wheel-rail system is also used as a rescue track for superconducting maglev trains and conventional maglev trains.

[0020] Optionally, the track body further includes a support structure connected to the bottom of the vertical section.

[0021] Optionally, the support structure, the vertical part, and the horizontal part form an I-shaped structure, with the side of the support structure facing the horizontal part being an inclined surface, and the end of the inclined surface connected to the vertical part being higher than the other end of the inclined surface.

[0022] Optionally, the track body is converted from an existing elevated ballastless track.

[0023] The train track provided by this invention has at least the following beneficial effects:

[0024] The horizontal and vertical sections are vertically connected, forming a T-shaped structure, which is the main structure of the track body. The track body serves to house the various track structures and provide load-bearing support. The T-shaped structure facilitates the installation of tracks for conventional maglev trains. A levitation traction surface is located on the lower surface of the horizontal section, housing the long stator of the linear motor used to drive the maglev train. Guide surfaces are located on both sides of the horizontal section to guide the conventional maglev train, thus meeting the requirements for its use. Furthermore, two wheel-rail systems are installed on the upper surface of the horizontal section to form a wheel-rail train track. When a wheel-rail train passes, the friction between the wheels and the rails achieves traction and braking. Moreover, a superconducting maglev train track is installed on the upper surface of the horizontal section, making the track a universal track, compatible with wheel-rail, conventional maglev, and superconducting maglev train systems.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The core of this invention is to provide a train track that is compatible with wheel-rail trains, conventional maglev trains, and superconducting maglev trains.

[0031] Please refer to Figure 1 This invention provides a train track, including a track body 1, wheel-rail 2, a superconducting maglev train track 3, and a conventional maglev train track 4. The track body 1 includes a horizontal section 11 and a vertical section 12, with the vertical section 12 perpendicularly connected to the bottom middle of the horizontal section 11. There are two wheel-rail 2, which are arranged parallel to each other on the upper surface of the horizontal section 11. The superconducting maglev train track 3 is located on the upper surface of the horizontal section 11 and between the two wheel-rail 2. The conventional maglev train track 4 includes a suspension traction surface 41 and a guide surface 42. The suspension traction surface 41 is located on the lower surface of the horizontal section 11 and on both sides of the vertical section 12. The guide surface 42 is located on both sides of the horizontal section 11.

[0032] In other words, the horizontal section 11 and the vertical section 12 are vertically connected to form a T-shaped structure, which is the main structure of the track body 1. The track body 1 serves to set up the various track structures and bear loads. It can be understood that the T-shaped structure facilitates the installation of the track 4 for the conventional maglev train. A suspension traction surface 41 is provided on the lower surface of the horizontal section 11. The suspension traction surface 41 is equipped with the long stator of the linear motor used to drive the maglev train, and guide surfaces 42 are provided on both sides of the horizontal section 11 to guide the conventional maglev train to meet the needs of the conventional maglev train. In addition, by setting two wheel rails 2 on the upper surface of the horizontal part 11, a wheel-rail train track is formed for use by wheel-rail trains. When the wheel-rail train passes, the traction and braking of the wheel-rail train are achieved by the friction between the wheels of the wheel-rail train and the wheel rails 2. Furthermore, by setting a superconducting maglev train track 3 on the upper surface of the horizontal part 11 for use by superconducting maglev trains, the train track is made into a universal track, realizing compatibility between wheel-rail trains, conventional maglev trains and superconducting maglev trains.

[0033] It should be noted that the specific structure and parameters of wheel-rail 2 can be found in relevant technologies and will not be elaborated upon here. For example, wheel-rail 2 is a steel rail, and the track gauge of the two wheel-rail 2s is the standard gauge of 1435mm to meet the requirements of wheel-rail train applications. Similarly, the track gauge of track 4 for conventional maglev trains can be designed according to the 2800mm gauge used in maglev trains. The specific structure and layout of track 4 for conventional maglev trains can be found in relevant technologies and will not be elaborated upon here. In addition, the specific structural form and layout of track 3 for superconducting maglev trains can also be found in relevant technologies and will not be elaborated upon here.

[0034] For example, as one implementation, in some embodiments, the track 3 for the superconducting maglev train includes a U-shaped groove 31 and a superconducting magnet 32. The U-shaped groove 31 is disposed on the upper surface of the horizontal part 11; the superconducting magnet 32 ​​is disposed on both sides of the groove wall of the U-shaped groove 31.

[0035] It is understandable that there is a gap between the superconducting magnets 32 on both sides of the U-shaped groove 31 so that the suspension guide frame of the superconducting maglev train can be embedded in the U-shaped groove 31 to run, thus meeting the application requirements of the superconducting maglev train.

[0036] Furthermore, in some embodiments, the U-shaped groove 31 is located at the center of the horizontal portion 11.

[0037] In other words, in this embodiment, the U-shaped groove 31 is placed at the center of the horizontal part 11 so that the horizontal part 11 is a left-right balanced structure, which helps to ensure the uniformity of the overall structural strength of the horizontal part 11, ensure the reliability and structural stability of the horizontal part 11, and thus improve the service life of the track body 1.

[0038] In addition, in some embodiments, the center of the gauge of the two wheel rails 2 coincides with the center of the track 3 for the superconducting maglev train.

[0039] In other words, in this embodiment, the two wheel rails 2 are symmetrically arranged about the superconducting maglev train track 3, thereby forming a left-right symmetrical structure on the upper surface of the horizontal part 11. This scheme helps to ensure the uniformity of the overall structural strength of the horizontal part 11, ensure the reliability and structural stability of the horizontal part 11, and thus improve the service life of the track body 1.

[0040] In addition, in some embodiments, the upper surface of the horizontal portion 11 is provided with a groove 111, and at least a portion of the wheel rail 2 is disposed in the groove 111.

[0041] In other words, in this embodiment, a groove 111 is provided on the upper surface of the horizontal part 11, and at least a part of the structure of the wheel rail 2 is provided in the groove 111, so that at least a part of the structure of the wheel rail 2 overlaps with the horizontal part 11 in the vertical direction. This solution is advantageous because by reasonably designing the size of the groove 111, the wheel rail 2 can have a suitable relative position with respect to the upper surface of the horizontal part 11, for example, the wheel rail 2 can protrude from the upper surface of the horizontal part 11 by a suitable distance.

[0042] Additionally, it is understandable that a railbed 21 can be set in the groove 111, and the wheel rail 2 can be placed on the railbed 21.

[0043] Furthermore, in some embodiments, the upper surface of the wheel rail 2 is flush with the upper surface of the horizontal portion 11.

[0044] In other words, in this embodiment, by completely placing the wheel rail 2 inside the groove 111, the upper surface of the wheel rail 2 is flush with the upper surface of the horizontal part 11, thereby preventing the wheel rail 2 from protruding from the upper surface of the horizontal part 11.

[0045] In addition, in some embodiments, the wheel-rail 2 is also used as a rescue track for superconducting maglev trains and conventional maglev trains.

[0046] In other words, the wheel-rail 2 in this embodiment is not only used by wheel-rail trains, but also by superconducting maglev trains and conventional maglev trains in rescue mode. When a superconducting maglev train or conventional maglev train is in rescue mode, the rescue wheel is lowered through a mechanical structure so that the rescue wheel lands on the wheel-rail 2. The wheel-rail 2 is used to support the superconducting maglev train or conventional maglev train to levitate, so that the superconducting maglev train or conventional maglev train can reach a traction-movable state.

[0047] Understandably, in this case, the distance between the rescue wheels of the superconducting maglev train and the conventional maglev train is the same as the distance between the wheel and rail 2, for example, 1435mm.

[0048] In addition, in order to improve the structural strength of the track body 1, in some embodiments, the track body 1 also includes a support structure 13 connected to the bottom of the vertical part 12.

[0049] In other words, this embodiment improves the structural strength of the track body 1 by providing a support structure 13 below the vertical part 12.

[0050] Furthermore, in some embodiments, the support structure 13, the vertical portion 12, and the horizontal portion 11 form an I-shaped structure, with the side of the support structure 13 facing the horizontal portion 11 being an inclined surface, and the end of the inclined surface connected to the vertical portion 12 being higher than the other end of the inclined surface.

[0051] It is understandable that the support structure 13, the vertical part 12, and the horizontal part 11 form an I-shaped structure. That is, the support structure 13 increases the area of ​​the bottom of the vertical part 12, which is beneficial to improving the overall stability of the track body 1. In addition, the side of the support structure 13 facing the horizontal part 11 is an inclined surface, and the end of the inclined surface that connects to the vertical part 12 is higher than the other end of the inclined surface. That is, there is a gradual transition between the support structure 13 and the vertical part 12, avoiding a direct vertical connection between the support structure 13 and the vertical part 12. Therefore, it is beneficial to improve the structural stability.

[0052] It should be noted that this embodiment does not limit the specific structure, material, or formation method of the support structure 13. For example, the support structure 13 is a reinforced concrete structure.

[0053] In addition, in some embodiments, the track body 1 is modified from an existing elevated ballastless track.

[0054] In other words, in this embodiment, the existing elevated ballastless track is modified to form the track body 1 in this embodiment of the invention. That is, no new construction is required. Existing resources are used to form a train track suitable for wheel-rail trains, conventional maglev trains and superconducting maglev trains. This allows for compatibility with conventional maglev trains and superconducting maglev trains while adapting to the construction of the "eight vertical and eight horizontal" rail network. This avoids damaging the "eight vertical and eight horizontal" trunk lines of wheel-rail trains. Compared with adding right-of-way or reducing the construction of existing wheel-rail 2 railway lines on the ground to form a maglev line that is only suitable for conventional maglev trains or superconducting maglev trains, the solution in this embodiment can reduce costs.

[0055] Of course, in other embodiments, if there are new requirements, the track body 1 provided in the embodiments of the present invention can be newly constructed, and a new compatible train track can be formed by setting the wheel rail 2, the superconducting maglev train track 3 and the normal maglev train track 4 on the track body 1.

[0056] It should also be noted that, in this specification, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0058] The train track provided by this invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this invention. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of this invention.
