Description

Technical Field

[0001] This invention relates to the field of magnetic levitation track maintenance equipment technology, specifically to an automatic dragging device for a high-speed maglev train model on a vacuum tube high-speed maglev track platform, which belongs to the automatic maintenance device of related products in the field of high-speed maglev transportation technology. Background Technology

[0002] With the continuous increase in the test speed of maglev trains at home and abroad, the continuous advancement of research on vacuum tube maglev train technology and the gradual improvement of related products, the technology of vacuum tube high-temperature superconducting pinned maglev trains is gradually becoming more in-depth.

[0003] The high-temperature superconducting pinned maglev train is anchored to a track by magnets, generating a strong magnetic field. Magnetic levitation then lifts the train and maintains its balance. Because the high-temperature superconducting pinned maglev train operates in a vacuum tube environment, there is a need for towing during testing. External towing can move the experimental train to any position within the vacuum tube.

[0004] In the current technology, the research and design of inspection, maintenance, patrol, cargo transportation, and towing of maglev train models inside vacuum tubes are still in the preliminary stage. Reliable, effective, and fully functional solutions have not yet been developed. In particular, there is a lack of experimental auxiliary devices that can simultaneously meet the requirements of automatic towing, allowing the train model to pass through a multi-functional inspection vehicle, and providing flexible lateral towing capabilities. Furthermore, how to fully and effectively utilize the experimental platform's working space and expand its applicability to accommodate towing of model vehicles of different sizes is a pressing practical problem that needs to be solved.

[0005] In view of this, there is an urgent need for an automatic dragging device for the experimental platform of high-temperature superconductivity in vacuum tubes. It should be able to automatically drag the train model through the multi-functional inspection vehicle, meet the requirements of flexible dragging in the lateral direction, and be applicable to model vehicles of different sizes. It should be reliable, effective and fully functional. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic dragging device for an experimental platform for high-temperature superconductivity in vacuum pipelines. It can not only meet the requirements of automatic dragging, but also the requirements of train models passing through multi-functional inspection vehicles, as well as the requirements of flexible dragging in the lateral direction of the dragging device. At the same time, it can be applied to model vehicles of different sizes and specifications, and has the characteristics of reliability, effectiveness and complete functions.

[0007] To achieve the above objectives, the technical solution of this invention is implemented as follows:

[0008] An automatic towing device is movably mounted on the end side of a vehicle frame. The device includes a mounting component, a rotating component, a lifting component, and a towing component. The rotating component is detachably fixed to the mounting component and moves in tandem with it. One end of the lifting component is fixed to the mounting component, and the other end extends downwards along the vertical direction. The towing component is detachably fixed to the rotating component and rotates together with it. A positioning part between the transverse plate and the mounting component allows for timely and rapid calibration of the device's position. A drive gear meshing with a rotary support, passing through the mounting component and connected to an external drive source, enables precise control of the mounting plate. Limiting parts on the left and right sides of the transverse plate flexibly fix the rotating component in the vehicle width direction, ensuring the towing component remains within the width direction of the train model vehicle, preventing deviation during transfer, and pulling the train model to one side of the vehicle frame. This satisfies strength and rigidity requirements while ensuring stable train model transfer each time, exhibiting reliability, effectiveness, and comprehensive functionality.

[0009] Furthermore, the mounting assembly includes a mounting frame, a lifting plate slidably mounted to the mounting frame via linear guide rails, the linear guide rails being paired and spaced apart on the mounting frame and extending along the vertical direction; it also includes a slider disposed between the lifting plate and the linear guide rails, one side of the slider being fixed to the lifting plate, and the other side being slidably mounted to the linear guide rails.

[0010] Furthermore, the rotating assembly includes a movable transverse plate, a rotary support, and a mounting plate that are mounted on the mounting assembly. The rotary support passes through the transverse plate and is rotatably mounted with the transverse plate. The mounting plate is fixed to the rotary support and is located on the end side of the rotary support away from the transverse plate.

[0011] Furthermore, the dragging assembly includes a fixed plate and a dragging plate. The fixed plate, after being folded and formed, has a cavity for accommodating the dragging plate. The dragging plate passes through the internal cavity of the fixed plate and is lockably connected to the fixed plate.

[0012] Furthermore, the dragging assembly also includes a pin that is detachably connected to the fixing plate and the dragging plate.

[0013] Furthermore, the end of the drag plate furthest from the fixed plate is machined into a tapered shape.

[0014] Furthermore, the dragging assembly also includes a buffer plate fixed to the dragging board, the buffer plate wrapping around the outer periphery of the dragging board and extending along the length of the dragging board.

[0015] Furthermore, the drag bar includes a vertical section, a bent section, and an extension section, wherein the extension section is connected to the vertical section through the bent section to form an inverted hook structure with the opening facing inward.

[0016] Furthermore, it also includes an inspection component, wherein the drag component and the inspection component are detachably fixed to the outer surface of the rotating component, and the drag component is arranged to extend 180° circumferentially from the inspection component.

[0017] Furthermore, it also includes a transfer component adapted to the dragging component. The transfer component includes an interface and a moving plate. The moving plate is processed into a slender tray. The interface is disposed on the end sides of both ends of the moving plate, forming an open receiving space between the interface and the moving plate.

[0018] The automatic towing device provided in the above embodiments has a tapered end of the towing plate away from the fixed plate, which facilitates assembly with the component to be towed, improving work efficiency. A detachable pin allows for easy locking of the towing plate to the fixed plate, enabling convenient and efficient replacement of the towing plate for towing different train models. A positioning part between the transverse plate and the mounting assembly allows for timely and rapid calibration of the inspection device's position. A drive gear meshing with the rotary support, connected to an external drive source after passing through the mounting assembly, enables precise control of the mounting plate. Limiting parts on the left and right sides of the transverse plate flexibly fix the rotating assembly in the width direction of the vehicle body, ensuring the towing assembly remains within the width direction of the train model's body, preventing deviation during transfer, and towing the train model to one side of the frame. This satisfies strength and rigidity requirements while ensuring stable train model transfer each time, exhibiting reliability, effectiveness, and comprehensive functionality.

[0030] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that if the embodiments of the present invention involve directional indications, such as up, down, left, right, front, back, etc., these directional indications are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. Furthermore, if the embodiments of the present invention involve descriptions such as "first," "second," "S1," "S2," "step one," "step two," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance, or implicitly indicating the number of technical features indicated or the order of method execution. Those skilled in the art will understand that anything that does not violate the inventive concept and is within the scope of the present invention should be included in the protection scope of the present invention.

[0032] like Figure 1 As shown, a schematic diagram of the installation of an automatic strip inspection device is illustrated according to some exemplary embodiments, such as... Figure 1 As shown, the inspection device 200 is movably mounted on the end side of the vehicle frame 100 for quality inspection of the inlay 300. The position of the movably mounted inspection device 200 relative to the vehicle frame 100 can be adjusted, making it suitable for test benches of different specifications, thereby enabling the inspection of inlays 300 of different sizes and specifications. Specifically, as... Figure 2As shown, in a preferred embodiment of the present invention, the inspection device 200 includes a mounting assembly 10, a rotating assembly 20, an inspection assembly 30, and a lifting assembly 40. The rotating assembly 20 is detachably fixed to the mounting assembly 10 and is configured to move together with it. The inspection assembly 30 is movably mounted on the rotating assembly 20 and rotates with the rotating assembly 20. One end of the lifting assembly 40 is fixed to the mounting assembly 10, and the other end extends downward along the vertical direction. Thus, by using the lifting assembly positioned vertically along the vehicle frame, the vertical position of the mounting assembly can be flexibly adjusted, thereby driving the vertical position of the inspection assembly mounted on the mounting assembly to achieve compatibility with test benches of different heights. The rotating assembly enables the inspection assembly to rotate, facilitating flexible position adjustment within its working space. This overcomes the limitation of existing technologies that can only inspect specific locations of the inserts, improving efficiency and expanding the inspection range of the inserts. It effectively meets the high-precision requirements of high-speed and ultra-high-speed maglev transportation, reducing and eliminating missed or false inspections.

[0033] In the preferred embodiment of this application, such as Figure 3 As shown, to accurately inspect strips of different specifications, the mounting assembly 10 includes a fixed frame 110, a lifting plate 11 slidably mounted to the fixed frame 100 via linear guide rails 12, the linear guide rails 12 being paired and spaced apart on the fixed frame 110, extending vertically; and a slider 13 disposed between the lifting plate 11 and the linear guide rails 12, one side of the slider 13 being fixed to the lifting plate 11, and the other side being slidably mounted to the linear guide rails 12. To prevent the lifting plate 11 from slipping from a height, a limit block 14 is provided at the bottom of the linear guide rail 12; preferably, the limit block 14 is a mechanical limit block, and further, the limit block is a limit block made of polyurethane material. Optionally, in this embodiment of the invention, the linear guide rail 12 is a T-shaped guide rod.

[0034] Preferably, in order to adjust the lifting plate 11 to a preset fixed position, at least two positioning parts 15 are spaced apart on the fixed frame 110 and arranged along the vertical direction of the fixed frame 110. Each positioning part 15 has an optical generating unit, and the lifting plate 11 is provided with a sensing part. Specifically, the positioning part 15 is a slotted photoelectric generating unit, matched with the sensing part of the lifting plate 11 to trigger commands. Thus, by using the sensing part on the lifting plate 11 and the positioning parts 15 at different positions, corresponding control commands can be triggered to achieve position monitoring and precise control of the lifting plate 11. Furthermore, to ensure the safety and reliability of the inspection device during operation, positioning parts 15 are provided at the highest and lowest extreme positions that the lifting plate 11 can reach. Further, the positioning part 15 is a slotted photoelectric device or a proximity switch, suitable for manual mode, where the rotating component 20 is only allowed to rotate upon receiving a relevant command, preventing it from touching other equipment or vacuum pipes when rotating in other positions.

[0035] In summary, paired linear guides guide and limit the movement of the lifting plate on a specific track; limit blocks at the bottom of the linear guides eliminate the safety risk of the lifting plate slipping from a height; sensors on the lifting plate, along with positioning units at different locations, trigger corresponding control commands to monitor and precisely control the position of the lifting plate, thereby driving the inspection component to precisely adjust and control its position in the vertical direction. Positioning units at the upper and lower limit positions of the lifting component ensure the safety and reliability of the inspection device during operation.

[0036] In the preferred embodiment of this application, such as Figure 5 and Figure 6 As shown, the inspection component 30, driven by the rotating component 20, is rotatably configured relative to the mounting component 10. To ensure that the inspection component 30 is positioned where operation is required, the rotating component 20 includes a movable transverse plate 21, a rotary support 22, and a mounting plate 23, all mounted on the mounting component 10. The rotary support 22 passes through the transverse plate 21 and is rotatably configured with respect to it. The mounting plate 23 is fixed to the rotary support 22 and located on the side of the rotary support 22 away from the transverse plate 21. To facilitate automatic adjustment of the inspection component 30's angle, a drive gear 24 meshes with the rotary support 22. The drive gear 24 passes through the mounting component 10 and is externally connected to a drive source to achieve precise control of the mounting plate 23.

[0037] Preferably, in order to enable flexible adjustment of the position of the inspection component 30, a linear guide rail 25 is further included between the transverse plate 21 and the mounting component 10. The linear guide rails 25 are arranged in pairs at intervals and extend in the vertical direction.

[0038] Optionally, to enable timely and rapid calibration of the inspection device position, a positioning part 26 is further included between the transverse plate 21 and the mounting assembly 10. The positioning part 26 includes a centering indicator plate 261 and a scale 262. The centering indicator plate 261 is fixed to the transverse plate 21 and extends towards the mounting assembly 10. The scale 262 is fixed to the mounting assembly 10, located on the top surface of the mounting assembly 10, and is configured to correspond with the centering indicator plate 261. In a preferred embodiment of the invention, the scale 262 is disposed on the top surface of the lifting plate 11 and extends along the length of the lifting plate 11.

[0039] Optionally, to ensure that the inspection accuracy is not affected even if the vehicle body shifts left or right during the movement of the inspection device, a limiting part 27 is also included, fixed to the mounting assembly 10 and disposed on the left and right sides of the transverse plate 21. The limiting part 27 includes a limiting adjustment plate 272 and a limiting post 271. The limiting adjustment plate 272 is fixed to the mounting assembly 10 and is telescopically adjustable with the limiting post 271. Specifically, the limiting post 271 is a combination structure of a guide shaft and a spring. Thus, by using the limiting parts disposed on the left and right sides of the transverse plate 21, the rotating assembly 20 is flexibly fixed in the width direction of the vehicle body, reducing detection errors caused by slight shifts in the inspection device during vehicle movement and improving inspection accuracy.

[0040] Optionally, in a preferred embodiment of the present invention, a drive unit 28 fixed to the mounting assembly 10 is further included. The drive unit 28 and the drive gear 24 are respectively disposed on both sides of the mounting assembly 10 and are linked with the drive gear 24. Specifically, the drive unit 28 includes a drive motor 281 that is linked with the drive gear 24 via a vacuum reducer 282.

[0041] Optionally, a position monitoring unit 29 is also included, disposed between the transverse plate 21 and the mounting plate 23. The position monitoring unit 29 includes a sensing unit 291 and a signal generating unit 292. The sensing unit 291 is fixed to the transverse plate 21 by a bracket, and the signal generating unit 292 is fixed to the peripheral side of the mounting plate 23, generating a signal along the axial direction of the mounting plate 23. Optionally, the position monitoring unit 29 is a slotted photoelectric or proximity switch. Thus, when the inspection component 30 needs to operate, the lifting component 40 actuates, driving the rotating component 20 to move along the linear guide rail 12. Through the measurement and sensing of the position monitoring unit 29, the working height position of the rotating component 20 can be accurately located, thereby enabling precise automated operation.

[0042] In summary, the rotating assembly provided by this invention, through the positioning part set between the transverse plate and the mounting assembly, can achieve timely and rapid calibration of the inspection device position; through the drive gear engaged with the rotary support, the drive gear passes through the mounting assembly and is connected to an external drive source to achieve precise control of the mounting plate; through the limiting parts set on the left and right sides of the transverse plate, the rotating assembly is flexibly fixed in the vehicle width direction, which can reduce the detection error caused by slight deviations of the inspection device during vehicle movement and improve the inspection accuracy.

[0043] In the preferred embodiment of this application, such as Figure 4 and Figure 7 As shown, the inspection component 30 includes a support frame 31 and a camera unit 33 fixed on the support frame 31. The camera unit 33 includes at least one camera fixed at intervals on the support frame 31, forming an open space between the cameras to accommodate the passage of the inlay 300. Thus, by using the camera units 33 spaced apart on the support frame 31, as the support frame 31 extends into the test bench under the combined action of the mounting component 10 and the rotating component 20, the inlay 300 to be inspected passes through the open space between the camera units 33, thereby quickly and conveniently capturing the influence of the circumferential side of the inlay 300, and thus determining the processing quality of the inlay 300. Specifically, the camera unit 33 includes a first camera group 331 and a second camera 332 fixed on the support frame 31. The first camera group 331 is a pair, with the lenses facing downwards and symmetrically arranged in the vertical direction; the second camera 332 is spaced apart below the first camera group 331, with the lenses facing upwards. Therefore, by setting the first camera group 331 and the second camera 332 at intervals with their lenses facing each other, an open space is constructed to accommodate the passage of the inlay 300. Thus, based on the downward-facing lenses of the paired first camera group, real-time imaging of the upper and side surfaces of the inlay passing between the first and second cameras can be achieved quickly, conveniently, and accurately. Simultaneously, the upward-facing second camera captures images of the lower left and right surfaces of the inlay, achieving real-time imaging of the upper, side, and lower left and right surfaces. This enables simultaneous multi-faceted inspection of the inlay, greatly improving inspection efficiency and enabling automated assembly line operations. After collecting the imaging data of the processed surfaces of the inlay, intelligent automatic labeling and diagnosis can be achieved, further enhancing the automation, intelligence, and precision of inlay inspection.

[0044] Preferably, the inspection component 30 further includes a limiting wheel 32 fixed to the support frame 31, located on the side opposite to the camera unit 33, and extending away from the camera unit 33. Specifically, the limiting wheel 32 is generally conical in shape and is fixed to the support frame 31 by a connecting plate. Preferably, the central axis of the limiting wheel 32 is parallel to the length direction of the support frame 31; further, the circumferential radius of the limiting wheel 32 is gradually reduced. Thus, by using the limiting wheel with a reduced circumferential radius, in conjunction with the flexible limiting of the rotating component 20, automatic engagement and positioning are achieved while offsetting the offset of the inspection device 200 along the width direction of the vehicle frame 100 during travel, ensuring that the inspection component always remains in the center of the insert 200.

[0045] Preferably, the imaging unit 33 further includes a third camera 333 fixed on the support frame 31. The third camera 333 is spaced below the second camera 332 and has its lens facing downwards. Thus, by using the third camera 333 with its lens facing downwards, images of the vertical surfaces of the strip 300 can be acquired simultaneously with the inspection of the upper and lower surfaces. Based on the same principle, comprehensive imaging of the surrounding sides of the strip 300 can then be achieved.

[0046] Optionally, to facilitate the location of defects in the inlay 300, the center line connecting the lenses of the second camera 332 and the third camera 333 is collinear with the center of symmetry of the first camera group 331. This unifies the position of the image data of the periphery of the inlay 300 acquired by the first camera group 331, the second camera 332, and the third camera 333. Then, through the inspected image information, the specific location of the defect in the inlay 300, as well as the specific side surface, can be quickly identified, significantly improving the efficiency of defect inspection and location. It is worth noting that the purpose of this invention is to provide an automatic inlay detection device with a specific mechanical structure suitable for specific occasions. The specific image recognition process, including how to locate the defect and what type of defect it is, can employ any method in the prior art, which will not be elaborated here.

[0047] Optionally, in the paired first camera group 331, the two cameras are arranged at 45° to the axis of symmetry to ensure the integrity of data acquisition on the upper surface of the strip 300. Further, to increase the field of view of the camera images and facilitate inspection of the vertical surface of the strip below, a prism 34 is included, fixed to the support frame 31 and located below the third camera 333. The third camera 333 and the prism 34 are spaced apart to form an opening space that allows the lower end of the strip 300 to pass through. Preferably, the prism 34 is a triangular prism, and the central apex of the triangular prism is located on the extension line of the line connecting the lenses of the second camera 332 and the third camera 333. Therefore, by using a prism positioned at the lower end of the third camera, the light from the surrounding area can be refracted and collected into the lens of the third camera, effectively expanding the imaging range of the third camera. This effectively overcomes the problem of limited imaging area caused by the installation position of the third camera, ensuring the breadth of imaging acquisition of the corresponding circumferential side of the strip, thereby improving the authenticity and reliability of the inspection, achieving full-range, blind-spot-free data acquisition coverage, and the entire operation is simple, flexible, safe and reliable.

[0048] In summary, the inspection component in this embodiment, based on the downward-facing lenses of the paired first camera group, can quickly, conveniently, and accurately capture real-time images of the upper surface of the inlay passing between the first and second cameras. Simultaneously, the upward-facing second camera captures images of the left and right lower surfaces of the inlay, achieving real-time imaging of both the upper and lower surfaces. This enables simultaneous multi-faceted inspection of the inlay, significantly improving inspection efficiency and enabling automated assembly line operations. Furthermore, after collecting imaging data from the processed surfaces of the inlay, intelligent automatic labeling and diagnosis are achieved, further enhancing the automation, intelligence, and precision of inlay inspection. The first camera group and the second... The images of the circumference of the inlay captured by the second and third cameras are positioned in the same location. By inspecting the image information, the specific location of the defect in the inlay and the specific side can be quickly identified, significantly improving the efficiency of defect inspection and location. The prism set at the lower end of the third camera refracts the light from the circumference and collects it into the lens of the third camera, effectively expanding the imaging range of the third camera. This effectively overcomes the problem of limited imaging area caused by the installation position of the third camera, ensuring the breadth of imaging acquisition of the corresponding circumference of the inlay, thereby improving the authenticity and reliability of the inspection, and achieving full-range, blind-spot-free data acquisition coverage. The entire operation is simple, flexible, safe and reliable.

[0049] Furthermore, the lifting assembly 40 can be of various suitable structures; in the preferred embodiment of this application, such as... Figure 3As shown, the lifting assembly 40 includes a second drive unit 41, a drive rod 42, and a fixed base 44. The second drive unit 41 is detachably fixed to the fixed frame 110 and located at the end away from the lifting plate 11. The drive rod 42 is fixed to the fixed frame 110 via the fixed base 44. One end of the drive rod 42 is fixed to the lifting plate 11, and the other end, which is opposite to it, is linked to the second drive unit 41. Preferably, it also includes a coupling 43 disposed between the second drive unit 41 and the drive rod 42. Optionally, the drive rod 42 is a T-shaped lead screw. The fixed base 44 is a lead screw fixing base.

[0050] The preferred embodiment of this application provides an automatic strip inspection device, such as... Figure 4 and Figure 8 As shown, the inspection component 30, driven by the rotating component 20, can rotate to the vertical direction. At this time, the axis of symmetry of the first camera group 331 in the camera 30 is collinear with the line connecting the camera centers of the second camera 332 and the third camera 333, and is parallel to the vertical direction. As the frame 100 moves, the strip 300 enters the open space between the first camera group 331 and the second camera 332, the third camera 333 and the prism 34, and simultaneously realizes image acquisition of the periphery of the strip 300. This allows for dynamic and complete data collection of the periphery of the strip 300, replacing manual visual inspection in the prior art. Based on motor drive, it can achieve automatic operation in a vacuum environment. When no operation is required, the inspection component, under the action of the rotating component 20, retracts to the upper end of the straight frame 100, and the rotating component 20 remains horizontal, facilitating the unobstructed passage of the high-speed maglev train through the vacuum tube inside the frame 100.

[0051] Furthermore, the drive motors used in this application are all vacuum servo motors, which are convenient for operation in a vacuum environment, and will not be described in detail here.

[0052] Furthermore, the cameras used in this application are all stereoscopic imaging cameras, and may also be line laser or 3D vision cameras, which will not be elaborated further here.

[0053] The automatic strip inspection device provided in the above embodiments of this application has at least the following characteristics:

[0054] The automatic strip inspection device provided in this application embodiment, through a lifting component arranged vertically along the vehicle frame, can flexibly adjust the vertical position of the mounting component, thereby driving the inspection component mounted on the mounting component to change its vertical position, achieving compatibility with test benches of different heights; through the driving of the rotating component, the inspection component can be rotated, facilitating flexible position adjustment of the inspection component within its working space, thus overcoming the limitation of existing technologies that can only inspect strips at specific locations, improving efficiency while expanding the inspection range of strips, effectively meeting the high-precision requirements of high-speed and ultra-high-speed maglev transportation, reducing and eliminating missed and false inspections; through paired The linear guide rail guides and limits the movement of the lifting platform on a specific track. A limit block at the bottom of the linear guide rail eliminates the safety risk of the lifting platform slipping from a height. Through a sensor on the lifting platform and positioning units at different locations, corresponding control commands are triggered to monitor and precisely control the position of the lifting platform. This, in turn, drives the inspection component to precisely adjust and control its position in the vertical direction. Positioning units at the upper and lower limit positions of the lifting component ensure the safety and reliability of the inspection device during operation. The positioning unit located between the transverse plate and the mounting component allows for timely and rapid positioning of the inspection device. Calibration; a drive gear meshing with a rotary support, the drive gear passing through the mounting assembly and connected to an external drive source, is used to achieve precise control of the mounting plate; limiting parts are provided on the left and right sides of the transverse plate to achieve flexible fixation of the rotating assembly in the vehicle width direction, which can reduce the detection error caused by slight displacement of the detection device during vehicle movement and improve the inspection accuracy; the inspection assembly in this embodiment, based on the downward-facing lenses of the paired first camera group, can quickly, conveniently and accurately achieve real-time imaging and capture of the progress of the upper surface of the strip passing between the second camera and the first camera, while the upward-facing second camera enables the left and right movement of the strip... The imaging capture of the lower surface enables real-time imaging capture of the upper surface and the left and right lower surfaces of the inlay, achieving simultaneous inspection of multiple surfaces of the inlay. This greatly improves inspection efficiency and enables automated assembly line operation. After collecting the imaging data of the processed surfaces of the inlay, intelligent automatic marking and automatic diagnosis are achieved, further enhancing the automation, intelligence, and precision of inlay inspection. By unifying the position of the image data of the periphery of the inlay collected by the first camera group, the second camera, and the third camera, the specific location of defects in the inlay and the specific side surface can be quickly located through the image information after inspection, significantly improving the efficiency of defect inspection and location.By using a prism positioned at the lower end of the third camera, peripheral light can be refracted and collected into the lens of the third camera, effectively expanding the imaging range of the third camera. This effectively overcomes the problem of limited imaging area caused by the installation position of the third camera, ensuring a broad imaging range of the corresponding peripheral side of the strip, thereby improving the authenticity and reliability of the inspection, achieving full-range, blind-spot-free data acquisition coverage. The entire operation is simple, flexible, safe, and reliable.

[0055] In the preferred embodiment of this application, such as Figure 2 , Figure 4 and Figure 9 As shown, in order to inspect, maintain, patrol, and transport the train model 400 in a vacuum tube environment, this application embodiment also provides an automatic dragging device. Based on the above embodiment, the automatic dragging device further includes a dragging component 50 detachably fixed to the rotating component 20 and rotatably disposed with the rotating component 20. One end of the dragging component 50 is detachably fixed to the rotating component 20, and the other end extends in a direction away from the rotating component 20. For example, in a preferred embodiment of the present invention, one end of the dragging component 50 is detachably fixed to the mounting plate 23 of the rotating component 20, and the other end extends radially away from the rotating component 20 along the mounting plate 23. The positioning part set between the transverse plate and the mounting component enables timely and rapid calibration of the inspection device position. The drive gear meshing with the rotary support, which passes through the mounting component and is connected to an external drive source, enables precise control of the mounting plate. The limiting parts set on the left and right sides of the transverse plate enable flexible fixation of the rotating component in the width direction of the vehicle body, ensuring that the towing component is in the width direction of the train model vehicle body and avoiding deviation during the transfer process. The train model is pulled to one side of the vehicle frame, which not only meets the strength and rigidity requirements, but also ensures that the train model can be transferred stably every time. It has the characteristics of reliability, effectiveness and complete functionality.

[0056] Optionally, in order to improve the effective utilization of the site, such as Figure 4 As shown, both the dragging component 50 and the inspection component 30 are detachably fixed to the outer surface of the rotating component 20. The dragging component 50 extends 180° circumferentially from the inspection component 30. Thus, by making the dragging component 50 and the inspection component 30 coplanar and extending in opposite directions at 180° circumferentially, when no operation is required, both the inspection component 30 and the dragging component 50 are positioned at the top of the mounting component 10, along the lateral direction of the mounting component 10. This avoids interference with the inspected parts when no inspection or dragging operation is needed, ensuring operational safety while reducing the footprint of the inspection platform.

[0057] Specifically, such as Figure 9 As shown, the towing assembly 50 includes a fixed plate 51 and a towing plate 52. The fixed plate 51, after being folded and formed, has a cavity to accommodate the towing plate 52. The towing plate 52 passes through the internal cavity of the fixed plate 51 and is lockably connected to the fixed plate 51. Preferably, the end of the towing plate 52 away from the fixed plate 51 is machined into a tapered shape to facilitate assembly with the component to be towed, improving work efficiency. Optionally, the towing assembly 50 further includes a pin 53 that passes through the fixed plate 51 and the towing plate 52 and is detachably connected to the fixed plate 51. Thus, the detachable pin 53 allows for extremely convenient locking of the towing plate 52 to the fixed plate 51, enabling convenient and efficient replacement of the towing plate 52 to traction different train models 400. Furthermore, to reduce wear between the drag plate assembly 50 and the component to be dragged during operation, and to reduce vibration and noise generated by rigid contact, a buffer plate 54 is also included, which wraps around the outer periphery of the drag plate 52 and extends along the length of the drag plate 52. Specifically, the buffer plate 54 wraps around the narrow side of the drag plate 52 at the end of the drag plate 52 away from the fixing plate 51.

[0058] In summary, the towing assembly provided by this invention has a tapered end of the towing plate away from the fixed plate, which facilitates assembly with the parts to be towed, thereby improving work efficiency. The towing plate and the fixed plate are locked together very easily by a detachable pin, which allows for convenient and efficient replacement of the towing plate to enable the towing of different train models.

[0059] In a preferred embodiment of the present invention, such as Figure 10 As shown, the system also includes a transfer component 60 adapted to the towing component 50. The transfer component 60 includes an interface 61 and a moving plate 62. The moving plate 62 is machined into an elongated support plate. The interface 61 is located on the end faces of both ends of the moving plate 62, forming an open receiving space between the interface 61 and the moving plate 62. Thus, the open receiving space formed between the interface 61 and the moving plate 62 facilitates cooperation with the towing component 50 to transfer the train model 400 mounted on the transfer component 60. In a specific embodiment of the invention, the transfer component 60 is a transfer part for transferring a maglev train, and the train model 400 is a maglev train model, including maglev train models of different sizes and models.

[0060] Specifically, the train model 400 is detachably fixed to the top of the transfer assembly. When the train model 400 is a small train model, the overall length of the transfer assembly 60 is longer than the length of the train model 400. In this case, the transfer assembly 60 protrudes from both ends of the train model 400 and extends along the length of the train model 400. At this time, the accommodating space between the interface 61 and the moving plate 62 located on the side of the transfer assembly 60 is located on the outer side of both ends of the train model 400. Driven by the rotating assembly 20 and the lifting assembly 40, and with the assistance of the positioning part 15 of the mounting assembly 10, the dragging assembly 50 can quickly and accurately insert the dragging plate 52 into the accommodating space between the interface 61 and the moving plate 62, thereby pulling and transferring the train model 400 fixed on the transfer assembly 60.

[0061] In another preferred embodiment of the present invention, such as Figure 11 As shown, to facilitate the transfer of medium to large-sized train models 400, the towing assembly 50 only requires replacing the appropriate towing plate 52. The towing plate 52 includes a vertical section 521, a bent section 522, and an extension section 523. The extension section 523 is connected to the vertical section 521 via the bent section 522 to form an open-facing hook structure. Specifically, one end of the extension section 523 is connected to the bent section 522, and the other end extends upwards along the length of the vertical section 521. Preferably, the end of the extension section 523 away from the bent section 522 is machined into a tapered shape to facilitate assembly with the component to be towed, improving operational efficiency. Furthermore, the buffer plate 54 wraps around the narrow side of the extension section 523.

[0062] When the train model 400 is a medium to large-sized train model, its length is longer than the overall length of the transfer assembly 60. The train model 400 covers the top of the transfer assembly 60, and both ends of the train model 400 extend beyond the ends of the transfer assembly 60. The towing assembly 50, by replacing the towing plate 52, uses the combined action of the rotating assembly 20 and the lifting assembly 40 to lower the extension 523 of the towing plate 52 to the forward position of the train model 400. With the assistance of the positioning part 15 of the mounting assembly 10, it is ensured that when the train model 400 moves to the predetermined position, the second interface (not shown in the figure) that cooperates with the towing plate 52 and the extension 523 of the towing plate 52 can be precisely aligned. Thus, driven by the lifting assembly 40, the towing plate 52 and the train model 400 are assembled, enabling the traction and transfer of the medium to large-sized train model.

[0063] Furthermore, in a preferred embodiment of the present invention, the buffer plate 54 is made of polyurethane material.

[0064] In summary, the automatic towing device in this embodiment of the present disclosure has a tapered end of the towing plate away from the fixed plate, which facilitates assembly with the component to be towed, improving work efficiency. A detachable pin allows for easy locking of the towing plate to the fixed plate, enabling convenient and efficient replacement of the towing plate for towing different train models. A positioning part between the transverse plate and the mounting assembly allows for timely and rapid calibration of the inspection device's position. A drive gear meshing with the rotary support, connected to an external drive source after passing through the mounting assembly, enables precise control of the mounting plate. Limiting parts on the left and right sides of the transverse plate flexibly fix the rotating component in the width direction of the vehicle body, ensuring the towing component remains within the width direction of the train model's body, preventing deviation during transfer, and towing the train model to one side of the frame. This satisfies strength and rigidity requirements while ensuring stable train model transfer each time, exhibiting reliability, effectiveness, and comprehensive functionality.
