Description

[0002] Maglev transportation is a high-potential, high-speed, energy-efficient, comfortable, and safe mode of rail transit. The track beam is a crucial component of the high-speed maglev train system, its primary function being to provide a smooth and stable track on the bridge, ensuring operational safety and passenger comfort. Maglev track beams are extremely sensitive to temperature; under significant temperature differences caused by sunlight, the vertical deformation of the track beam can reach 2-3 mm, and the levitation magnets will also deform accordingly. This deformation produces a noticeable "track irregularity," which, in extreme cases, can even pose safety hazards.

[0003] In existing technologies, strengthening the track beam to reduce deformation is a common and costly approach. However, if the track beam does deform, adjustment becomes very difficult, making it hard to eliminate the impact of temperature on the track beam's deformation and unevenness, which affects the safety of maglev train operation.

[0004] Therefore, how to reduce the impact of track beam deformation due to temperature on the operational safety of maglev trains is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0039] 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.

[0040] The core of this invention is to provide an adjustment device and control method for a maglev track, which can reduce the impact of track beam deformation due to temperature on the operational safety of maglev trains.

[0041] For a specific embodiment of the magnetic levitation track adjustment device provided by this invention, please refer to [the relevant documentation / reference]. Figures 1 to 7 It includes a working platform 1, a levitation magnet 4, a detection and adjustment component 3, and a controller 51.

[0042] The working platform 1 is designed to deform synchronously with the track beam 2, specifically through vertical deformation. The working platform 1 can be installed on the bottom surface of the flange 21 of the track beam 2 in the maglev track. Specifically, the working platform 1 is made of bridge steel plate, and its dimensions can be customized, for example, 60cm in length, 60cm in width, and 20mm in thickness. Furthermore, the working platform 1 can be bolted (e.g., large bolts with a diameter of 5cm) to the bottom surface of the flange 21 of the track beam 2. Figure 2 As shown, the working platform 1 is fixed to the flange 21 with 12 bolts. In other embodiments, the working platform 1 can also be directly integrally formed to the track beam 2, or fixed to the track beam 2 by welding or other methods.

[0043] The levitation magnets 4 are arranged side by side on one side of the work platform 1. During use, refer to... Figure 1 The levitation magnet 4 is located below the working platform 1. A levitation magnet coil 41 is installed on the levitation magnet 4. The levitation magnet 4 is used to cooperate with the train and use magnetic force to levitate the train.

[0044] The detection and adjustment assembly 3 includes a telescopic actuator and a temperature detection device 57. The telescopic actuator connects the levitation magnet 4 to the working platform 1. The temperature detection device 57 is mounted on the working platform 1 and can detect the real-time temperature value of the track beam 2. Specifically, the temperature detection device 57 is a digital temperature sensor. In use, such as... Figure 1 As shown, optionally, multiple detection and adjustment components 3 can be sequentially arranged on the track beam 2 along its extension direction. The telescopic actuator in each detection and adjustment component 3 can adjust the height or position of the levitation magnet 4 at the position connected to the detection and adjustment component 3 according to the detection of the temperature sensor. The position connected to the detection and adjustment component 3 is a preset detection point, thereby preventing different positions of the levitation magnet 4 from deforming synchronously with the track beam 2 that deforms due to temperature, and keeping the levitation magnet 4 smooth.

[0045] The controller 51 is used for control. The temperature detection device 57 and the telescopic actuator are both communicatively connected to the controller 51. Specifically, the controller 51 is a microcomputer. The controller 51 determines the deformation of the track beam 2 based on the temperature detected by the temperature detection device 57, and controls the telescopic actuator in the same detection and adjustment assembly 3 to adjust the position of the levitation magnet 4. The relationship between temperature and the deformation of the track beam 2 can be pre-stored in the controller 51 and can be directly recalled during use.

[0046] The maglev track adjustment device provided in this embodiment can solve the problem of track unevenness caused by temperature deformation of the maglev track beam 2. By monitoring the temperature and judging the amount of deformation of the track beam 2, the height of the corresponding position of the levitation magnet 4 can be adjusted to avoid the levitation magnet 4 deforming synchronously with the track beam 2, thus avoiding unevenness of the levitation magnet 4. This avoids the impact of temperature deformation of the track beam 2 on train operation, and can improve driving safety and ride comfort.

[0047] Furthermore, such as Figure 2 and Figure 7 As shown, the detection and adjustment assembly 3 also includes an angle detection device 55 and a spacing detection device 56. The angle detection device 55 is used to detect the tilt angle of the levitated magnet 4, and the spacing detection device 56 is used to detect the levitated spacing of the levitated magnet 4 relative to the working platform 1. The angle detection device 55 and the spacing detection device 56 are mounted on the working platform 1. Specifically, the angle detection device 55 is a laser tilt meter, and the spacing detection device 56 is a laser rangefinder.

[0048] The angle detection device 55 and the spacing detection device 56 are communicatively connected to the controller 51, enabling error control of the adjustment of the levitation magnet 4. Specifically, the controller 51 connects to and / or controls the telescopic actuator, temperature detection device 57, angle detection device 55, and spacing detection device 56 via a wireless sensor network. After the telescopic actuator adjusts the position of the levitation magnet 4, the controller 51 determines whether the tilt angle value of the levitation magnet 4 meets the preset tilt angle requirement based on the tilt angle value detected by the angle detection device 55. The controller 51 also determines whether the levitation spacing value meets the preset spacing requirement based on the levitation spacing value detected by the spacing detection device 56 after the telescopic actuator adjusts the position of the levitation magnet 4. The preset tilt angle requirement and the preset spacing requirement correspond to the allowable error range of the tilt angle value and the spacing value, respectively.

[0049] Based on the detection by the angle detection device 55 and the spacing detection device 56, and by comparing the detected values ​​with the preset tilt angle requirements and preset spacing requirements, it is possible to detect whether the suspended magnet 4 is properly adjusted. If the adjustment error is large, the action of the telescopic actuator can be further controlled. Of course, in other embodiments, only one of the angle detection device 55 and the spacing detection device 56 can be set, and the error can be judged from one of the tilt angle value and the suspension spacing value.

[0050] Furthermore, such as Figure 2 and Figure 4As shown, the telescopic actuator includes a hydraulic tank 31 and a telescopic column 32 retractably connected to the hydraulic tank 31. The telescopic column 32 is connected to the levitation magnet 4, and the hydraulic tank 31 is connected to the working platform 1. The hydraulic tank 31 is communicatively connected to a controller 51 to control the oil level in the hydraulic tank 31 and drive the telescopic column 32 to extend and retract. The levitation magnet 4 is hydraulically controlled, providing good load-bearing capacity. Since the telescopic actuator drives the levitation magnet 4 to rise and fall during use, the telescopic column 32 can be referred to as a lifting column. Of course, in other embodiments, the telescopic actuator can also be a motor.

[0051] Furthermore, such as Figure 2 and Figure 3 As shown, the adjustment device also includes a support base 34, which connects and supports the working platform 1 and the hydraulic tank 31 to ensure the connection strength of the hydraulic tank 31 on the working platform 1. Specifically, the support base 34 includes two parallel triangular plates 341 and a connecting plate 342 fixed between the two triangular plates 341. The two triangular plates 341 and the connecting plate 342 form a U-shaped plate. Optionally, the support base 34 can be formed by bending a single plate, for example, using 10cm Q235 steel. The sides of the two triangular plates 341 are welded to the outer surface of the hydraulic tank 31, and the connecting plate 342 is bolted to the working platform 1, for example, using three medium-sized bolts with a diameter of 3cm. More specifically, three support bases 34 are provided between each hydraulic tank 31 and the working platform 1.

[0052] Furthermore, such as Figure 2 and Figure 4 As shown, the telescopic actuator also includes a guide post 33, which is positioned between the levitation magnet 4 and the telescopic post 32. Both ends of the guide post 33 are threadedly fixed to the levitation magnet 4 and the telescopic post 32, respectively. The length of the guide post 33 can be freely selected, facilitating the connection between the telescopic actuator and the levitation magnet 4. Specifically, the telescopic post 32 is a threaded post, connected to the guide post 33 via a connecting nut 35, ensuring that the guide post 33 has the same displacement as the telescopic post 32 when it extends or retracts. The guide post 33 is also connected to the levitation magnet 4 via a nut, thus ensuring that the displacement of the levitation magnet 4 is the same as the displacement generated by the telescopic post 32.

[0053] Furthermore, the hydraulic tank 31 and the telescopic column 32 are sealed together, specifically by using sealing rubber such as fluororubber sealing rings, which have excellent airtightness, high temperature resistance, oxidation resistance, and weather resistance, and can effectively prevent oil leakage and foreign objects from entering the hydraulic tank 31.

[0054] Furthermore, the adjustment device also includes a control cabinet 5, allowing all detection devices to be uniformly assembled on the work platform 1. The control cabinet 5 is equipped with a magnetic base 52, and the controller 51, temperature detection device 57, angle detection device 55, and spacing detection device 56 can be magnetically fixed to the magnetic base 52. The wall surface of the control cabinet 5 near the levitation magnet 4 is a light-transmitting surface, for example, it can be made of tempered glass 54, so that the temperature detection device 57, angle detection device 55, and spacing detection device 56 can transmit detection signals such as laser light to detect the relevant parameters of the levitation magnet 4. Specifically, the controller 51 is fixed to a mounting plate 53, which can be a steel plate welded to the outer surface of the control cabinet 5. The mounting plate 53 is anchored to the work platform 1 by bolts, making the control cabinet 5 easy to assemble and disassemble. Optionally, the bolts are small bolts with a diameter of 1.5 cm, and the number of bolts is 4.

[0055] The maglev track adjustment device provided in this embodiment can reduce the overall track unevenness caused by temperature deformation of the track beam 2 by adjusting the position of the levitation magnet 4 connected to the track beam 2. To achieve accurate adjustment, it is also equipped with a database storing deformation caused by bridge temperature gradient and an error judgment mechanism to improve the accuracy of adjusting the position of the levitation magnet 4, thereby reducing safety hazards, improving ride comfort, and enhancing the stability and safety of the maglev train.

[0056] In addition to the aforementioned adjustment device, the present invention also provides a magnetic levitation track, which includes an adjustment device. Specifically, the adjustment device can be any of the adjustment devices provided in the above embodiments, and the beneficial effects can be referred to the respective embodiments above. For example... Figure 1 As shown, the maglev track includes a track beam 2, which may specifically include a composite beam and a track slab beam on the beam. The working platform 1 of the adjustment device is fixed to the bottom surface of the flange 21 of the track beam 2, and the levitation magnet 4 is located below the working platform 1. Optionally, multiple adjustment devices are sequentially arranged along the extension direction of the track beam 2; for example, five adjustment devices are evenly arranged for each 24m span of the track beam 2. The levitation magnet 4 in all adjustment devices can be an integrally formed structure.

[0057] In this embodiment, the maglev track, due to the application of the above-mentioned adjustment device, although the track beam 2 will deform due to temperature, the vertical deformation and tilt angle of the levitation magnet 4 can be adjusted by this adjustment device, thereby reducing the unevenness of the maglev track. Moreover, the adjustment device has the advantages of inexpensive materials, light weight, and simple manufacturing and construction, providing a safe and reliable device for the track unevenness effect caused by temperature deformation of the track beam 2.

[0058] In addition to the aforementioned adjustment device and maglev track, the present invention also provides a control method for the adjustment device of the maglev track, which is applied to the aforementioned adjustment device.

[0059] The control method includes:

[0060] S1: Receive the temperature value of the preset detection point on the track beam 2, wherein the working platform 1 is fixed at the preset detection point on the track beam 2.

[0061] S2: Determine the deformation of the track beam 2 based on the temperature value, and control the telescopic actuator to extend and retract so that the suspended magnet 4 remains in a preset smooth state.

[0062] The database of deformation caused by the temperature gradient between the bridge and the deformable beam 2 can be pre-stored in the controller 51.

[0063] Specifically, the controller 51 can pre-store the deformation of the track beam 2 and the distance of the telescopic actuator driving the levitation magnet 4 to telescopically move. Specifically, after the deformation is greater than 0 or another set value, the telescopic actuator performs the corresponding telescopic movement.

[0064] Furthermore, after S2, an error judgment step can be performed, including:

[0065] S3: Receive the verification value, which includes the tilt angle of the levitation magnet 4 and / or the levitation distance between the levitation magnet 4 and the working platform 1.

[0066] S4: Determine whether the verification value is within the preset error range. If not, repeat the control of the telescopic driver to extend and retract, so that the suspended magnet 4 remains in the preset smooth state.

[0067] The tilt angle and suspension distance values ​​each correspond to separate error range values. When the tilt angle value is within the corresponding error range, it is determined whether the tilt angle value of the suspension magnet 4 meets the preset tilt angle requirement. When the suspension distance value is within the corresponding error range (e.g., 0.1 mm), it meets the preset distance requirement. If either of these values ​​is outside the corresponding error range, the suspension magnet 4 is not actually maintaining the preset smooth state. Adjusting the suspension magnet 4 again according to the preset rules can improve the reliability of the adjustment.

[0068] When this control method is applied to the adjustment device, the control process can be implemented through the controller 51. The working principle includes: the temperature detection device 57 detects the temperature value of the track beam 2 at its set position in real time and transmits it to the controller 51 through a wireless sensor network. The controller 51 stores a database of the deformation caused by the temperature gradient of the bridge. Based on the database, it automatically retrieves the vertical deformation and horizontal inclination value of the detection point on the track beam 2. The controller 51 controls the oil supply or extraction of the hydraulic tank 31, and the telescopic column 32 will rise and fall. During the rising and falling process, there will be no oil leakage due to the presence of sealing rubber. The suspension gap and inclination value between the levitation magnet 4 and the track beam 2 will change, and the levitation magnet 4 will return to the smooth state when the track beam 2 is not deformed.

[0069] After the hydraulic tank 31 is adjusted for the first time, the angle detection device 55 measures the horizontal tilt angle of the levitation magnet 4, and the gap detection device 56 measures the suspension gap value. These values ​​are then transmitted to the controller 51 via a wireless sensor network. The controller 51 estimates the error between the measured tilt angle and suspension gap values ​​and the horizontal tilt angle and vertical deformation of the detection point on the track beam 2, respectively. If the error meets the requirements, the adjustment process ends. If the error does not meet the requirements, the controller 51 will control the hydraulic tank 31 to work again, repeating the above process until the measurement error calculated by the controller 51 meets the requirements, at which point the adjustment process ends.
