Description

Technical Field

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

[0002] In the field of rail vehicle technology, it is well known that due to differences in operating principles, track types, etc., there are significant differences in the track structure and composition of maglev train tracks and railway rails. Currently, maglev train tracks and railway rails cannot be shared, making it impossible for maglev trains and railway trains to operate on the same line.

[0003] Therefore, how to provide a track device that is compatible with both maglev trains and railway trains is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a track device that is compatible with both maglev trains and railway trains.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A track device, comprising:

[0007] The track slab has magnetic levitation traction surfaces at the bottom of both sides along the width direction, guide surfaces at the sides of both sides along the width direction, and sliding surfaces at the top of both sides along the width direction.

[0008] The top of the track slab is also provided with two parallel steel rails, which extend along the length of the track slab, and the two steel rails are respectively located on the side of the two sliding surfaces away from the edge of the track slab.

[0009] Optionally, the track plate has a plurality of spaced first grooves along its length, the first grooves extend along the width, and a fixed beam is embedded in the first groove, and the rail is connected to the fixed beam.

[0010] Optionally, the fixed beam is provided with a second groove, and the track plate is provided with a third groove. The second groove and the third groove are connected to each other to form a track groove extending along the length direction of the track plate, and the rail is disposed in the track groove.

[0011] Optionally, the fixing beam is a steel component formed by a mold, and / or the fixing beam is connected to the track plate by fasteners.

[0012] Optionally, a first vibration damping element is provided between the fixed beam and the track slab and / or between the rail and the track slab.

[0013] Optionally, a first adjusting pad is provided between the fixed beam and the track slab and / or between the rail and the track slab.

[0014] Optionally, the rail is connected to the fixed beam via fasteners.

[0015] Optionally, the top of each side of the track plate along the width direction is provided with a first mounting plate, the top surface of the first mounting plate forms the sliding surface, and the steel rail is provided thereon.

[0016] Optionally, the track slab is a T-shaped track slab of an existing maglev track.

[0017] Optionally, the bottom of the track plate is provided with a reinforcing base, and the reinforcing base has a preset height.

[0018] The track device provided by this invention has at least the following beneficial effects:

[0019] The track slab integrates a maglev traction surface, a guide surface, and a sliding surface, as well as steel rails. The maglev traction surface, guide surface, and sliding surface serve as interfaces for maglev trains, allowing them to run along the track slab. The steel rails serve as interfaces for railway trains, enabling them to run along the track slab. In other words, this track device utilizes the track slab as a support structure for the railway train rails. In particular, because the track slab integrates interfaces for maglev trains, it can function as both a conventional maglev track slab and a rail support slab. The interfaces for maglev trains and railway trains do not interfere with each other, allowing maglev and railway trains to run on the same line. Therefore, this track device is compatible with both maglev and railway trains. Attached Figure Description

[0027] 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.

[0028] The core of this invention is to provide a track device that is compatible with both maglev trains and railway trains.

[0029] Please refer to Figure 1 This invention provides a track device, including a track slab 1. The bottom of both sides of the track slab 1 along its width direction are respectively provided with magnetic levitation traction surfaces 11, the sides of the track slab 1 along its width direction are respectively provided with guide surfaces 12, and the top of both sides of the track slab 1 along its width direction are respectively provided with sliding surfaces 13. The top of the track slab 1 is also provided with two parallel steel rails 2, which extend along the length direction of the track slab 1. The two steel rails 2 are respectively located on the side of the two sliding surfaces 13 away from the edge of the track slab 1.

[0030] In other words, the track slab 1 in this embodiment of the invention is provided with a maglev traction surface 11, a guide surface 12, and a sliding surface 13, and also integrates a steel rail 2. The maglev traction surface 11, guide surface 12, and sliding surface 13 serve as interfaces for maglev trains, allowing them to run along the track slab 1; the steel rail 2 serves as an interface for railway trains, enabling them to run along the track slab 1. That is, this track device utilizes the track slab 1 as a supporting structure for the railway train's steel rail 2. In particular, since the track slab 1 integrates the maglev train's interface, it can simultaneously support the steel rail 2 using a conventional maglev track slab. The maglev train's interface and the railway train's interface do not interfere with each other, enabling maglev trains and railway trains to run on the same line. In other words, this track device is compatible with both maglev trains and railway trains.

[0031] It should be noted that the specific arrangement of the magnetic levitation traction surface 11, guide surface 12 and sliding surface 13 can be the same as the corresponding arrangement of the magnetic levitation traction surface 11, guide surface 12 and sliding surface 13 on the existing magnetic levitation track slab 1, and will not be described again here.

[0032] To achieve the setting of rail 2, such as Figure 2 As shown, in some embodiments, the track plate 1 is provided with a plurality of spaced first grooves along its length direction, the first grooves extend along the width direction of the track plate 1, and a fixed beam 3 is embedded in the first groove, and the rail 2 is connected to the fixed beam 3.

[0033] In other words, this embodiment achieves the rail 2 being embedded in the top of the track slab 1 by creating a first groove in the track slab 1, embedding a fixing beam 3 within the groove, and connecting the rail 2 to the fixing beam 3. This is equivalent to embedding the rail 2 within the track slab 1. This arrangement of the rail 2 does not affect the height of the sliding surface 13 at the top of the track slab 1, ensuring that the interface for the maglev train and the interface for the railway train on the track slab 1 are completely decoupled and do not interfere with each other. Furthermore, it can be understood that by embedding the fixing beam 3 in the first groove and arranging the rail 2 along the length of the track slab 1, the fixing beam 3 is spaced out along the path of the rail 2. This allows the fixing beam 3 to enhance the overall structural strength and rigidity of the rail 2 installation, thereby improving structural reliability.

[0034] It should be noted that this embodiment does not limit the spacing between the first grooves or their arrangement. For example, the first grooves are evenly spaced.

[0035] Furthermore, in some embodiments, the fixed beam 3 is provided with a second groove, and the track plate 1 is provided with a third groove. The second groove and the third groove are connected to each other to form a track groove 14 extending along the length direction of the track plate 1 (e.g., Figure 1 As shown in the figure, the rail 2 is installed in the track groove 14.

[0036] In other words, this embodiment uses a longitudinal groove along the length of the track plate 1 to accommodate the bottom of the rail 2. It can be understood that the longitudinal groove corresponding to the position of the fixed beam 3 is the second groove on the fixed beam 3, and the longitudinal groove corresponding to the position of the non-fixed beam 3 on the track plate 1 is the third groove on the track plate 1. That is, the second and third grooves together form the track groove 14, used to install the bottom of the rail 2. In other words, this solution utilizes the combined action of the fixed beam 3 and the track plate 1 to accommodate and support the rail 2, facilitating the fixing of the rail 2.

[0037] It should be noted that this embodiment does not limit the formation method or specific material of the fixed beam 3. In some embodiments, the fixed beam 3 is a steel part formed by a mold.

[0038] Understandably, the fixed beam 3 is formed by mold, which helps to ensure the processing accuracy and dimensional stability of the fixed beam 3, and is suitable for assembly line production with high production efficiency; while the steel fixed beam 3 can improve the structural rigidity of the fixed beam 3 and ensure the reliability of the fixed beam 3.

[0039] In addition, the above embodiments do not limit the specific connection method between the fixed beam 3 and the track plate 1, as long as the connection between the fixed beam 3 and the track plate 1 can be achieved.

[0040] In some embodiments, the fixing beam 3 is connected to the track plate 1 by fasteners. Exemplarily, the fixing beam 3 is installed in the first groove of the track plate 1 by bolts, which is a simple and easy-to-implement fixing structure.

[0041] In addition, such as Figure 1 As shown, in some embodiments, a first damping element 4 is provided between the fixed beam 3 and the track slab 1 and / or between the rail 2 and the track slab 1.

[0042] In other words, this embodiment provides a first vibration damping element 4 between the fixed beam 3 and the track slab 1, and / or between the rail 2 and the track slab 1, to dampen the rail 2. This can buffer the impact of the rail 2, reduce the transmission of vibration to the track slab 1, and prevent long-term vibration from causing structural fatigue. In addition, the first vibration damping element 4 can also reduce the transmission of rail 2 vibration to bridges, tunnels or the ground through the track slab 1, thereby reducing structural noise. Furthermore, the first vibration damping element 4 can also compensate for minor unevenness of the rail 2, reduce the bumpy feeling when the train passes, and improve driving comfort and safety.

[0043] It should be noted that this embodiment does not limit the specific structure and material of the first damping member 4, as long as the first damping member 4 can play a damping role. For example, the first damping member 4 includes an elastic pad or a rubber pad, etc.

[0044] In addition, in some embodiments, a first adjusting pad is provided between the fixed beam 3 and the track plate 1 and / or between the rail 2 and the track plate 1.

[0045] In other words, this embodiment uses a first adjusting shim between the fixed beam 3 and the track plate 1, and / or between the rail 2 and the track plate 1, to adjust the geometry of the rail 2, thereby precisely adjusting the height of the rail 2, ensuring a smooth rail surface, and also helping to ensure the levelness of the two rails 2. In addition, the first adjusting shim can prevent the fixed beam 3 from directly contacting and rubbing against the track plate 1 and / or the rail 2, thereby reducing metal fatigue and wear, and extending the service life of the fixed beam 3, the rail 2 and the track plate 1.

[0046] Furthermore, in some embodiments, the first adjusting shim can be an insulating shim. It is understood that in electrified railway trains, insulating shims prevent leakage current between the rail 2 and the track slab 1, thus protecting the signaling system and preventing corrosion.

[0047] It should be noted that this embodiment does not limit the specific connection method between the rail 2 and the fixed beam 3, as long as the connection between the rail 2 and the fixed beam 3 can be achieved.

[0048] In some embodiments, the rail 2 is connected to the fixed beam 3 via fasteners. It should be noted that the specific structure of the fasteners can be referred to in the relevant art for the specific structure of the fastener system in which the rail 2 is connected to the sleeper or track slab 1 via a fastener system, and will not be repeated here.

[0049] Understandably, when the rail 2 is embedded in the top of the track slab 1, it is necessary to create a first groove, a second groove, and a third groove on the top of the track slab 1. This will affect the rigidity of the original track slab 1. For applications with high rigidity requirements, in order to meet the requirements of the rail 2, such as... Figure 3 As shown, in some embodiments, the top of both sides of the track plate 1 along its width direction is provided with a first mounting plate 5, the top surface of the first mounting plate 5 is formed with a sliding surface 13, and the top surface of the first mounting plate 5 is provided with a rail 2.

[0050] In other words, this embodiment adds a first mounting plate 5 to the top of the track slab 1, and then places the rail 2 on the first mounting plate 5, thereby increasing the thickness of the track slab 1 through overlapping, and thus realizing the installation of the rail 2. This solution increases the thickness of the track slab 1 through the first mounting plate 5, thereby increasing the rigidity of the track slab 1 and improving the reliability of the overall structure. At the same time, it avoids slotting the top of the track slab 1, thus avoiding affecting the structure of the track slab 1 itself and ensuring the rigidity of the track slab 1. In addition, it should be noted that after adding the first mounting plate 5 to the top of the track slab 1, a sliding surface 13 is formed on the top surface of the first mounting plate 5 to ensure the normal operation of the maglev train.

[0051] In addition, in some embodiments, a second vibration damper and / or a second adjusting pad are provided between the first mounting plate 5 and the track plate 1. The specific structure and material of the second vibration damper and the second adjusting pad can be referred to the first vibration damper 4 and the first adjusting pad, and will not be described in detail here.

[0052] In other embodiments, the solution may also be as follows: Figure 4As shown, the top of both sides of the track plate 1 along its width direction are respectively provided with second mounting plates 6, and the top surface of the second mounting plates 6 is used to form a sliding surface 13; a recessed space is formed between the two second mounting plates 6, and two spaced third mounting plates 7 are provided in the recessed space. The third mounting plates 7 are connected to the top of the track plate 1, and the rail 2 is provided on the third mounting plates 7.

[0053] In other words, this embodiment adds a second mounting plate 6 and a third mounting plate 7 to the top of the track plate 1. The top surface of the second mounting plate 6 forms the sliding surface 13 for the maglev train, and the top of the third mounting plate 7 is used to install the rail 2. This allows the sliding surface 13 and the rail 2 to be mounted on different mounting plates, which is beneficial for the independent processing of the second mounting plate 6 and the third mounting plate 7 to ensure the accuracy of their respective processing surfaces. This also helps to ensure that the installation of the sliding surface 13 and the rail 2 meets their respective requirements.

[0054] In addition, in some embodiments, a third vibration damper and / or a third adjusting pad are provided between the third mounting plate 7 and the track plate 1. The specific structure and material of the third vibration damper and the third adjusting pad can be referred to the first vibration damper 4 and the first adjusting pad, and will not be described in detail here.

[0055] In other embodiments, the track plate 1 may have protrusions on both sides of its top, forming a recessed space between them. That is, the second mounting plate 6 may be a protrusion structure inherent to the track plate 1 itself, meaning the second mounting plate 6 and the track plate 1 are integrally formed. This facilitates the assembly of the track device.

[0056] In some embodiments, the track slab 1 is a T-shaped track slab of an existing maglev track.

[0057] It should be noted that in this embodiment, the track slab 1 is a T-shaped track slab of the existing maglev track. This means that the track device in this embodiment is based on the existing maglev track slab 1, utilizing the gap between the train and the track slab 1 in the middle area and the thickness of the track slab 1, to arrange the railway train rails 2, fasteners, etc. on the upper part of the maglev track slab 1. This integrates the railway train rail interface into the existing maglev track slab 1, based on the original maglev suspension, guide, and sliding surface 13 interface, and the two do not interfere with each other. That is, by improving the existing maglev track slab 1, the defect that the existing maglev track slab 1 structure can only provide a maglev support surface interface is overcome, so that the existing maglev track slab 1 can also provide the support surface required for railway train operation, achieving the purpose of maglev trains and railway trains running on the same line.

[0058] To ensure the reliability of track slab 1 structure, such as Figure 1 and Figure 4As shown, in some embodiments, the bottom of the track plate 1 is provided with a reinforcing base 8, which has a preset height.

[0059] In other words, this embodiment improves the rigidity of the track slab 1 by setting a reinforcing base 8 at its bottom, thereby ensuring the overall structural reliability of the track device. This allows for the addition of railway train rails 2 on top of the track slab 1 through embedding or overlapping. It should be noted that this embodiment does not limit the specific structure of the reinforcing base 8, as long as it can improve the rigidity of the track slab 1. For example, the reinforcing base 8 can be a steel base or a concrete base. Furthermore, the reinforcing base 8 has a preset height to ensure sufficient rigidity. It is understood that the reinforcing base 8 is installed on existing railway foundations or bridges.

[0060] 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.

[0061] 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.

[0062] The track device 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.
