Description

Technical Field

[0001] The present invention relates to the technical field of railway maintenance, and specifically provides a mobile railway track inspection and maintenance device. Background Art

[0002] Railway track inspection and maintenance are important links in the railway system to ensure the safe and stable operation of railway lines. Track inspection refers to comprehensively checking the geometric state, structural health, wear condition, and possible defects of railway tracks through various means, so as to timely detect track problems and avoid accidents caused by track damage. Railway track maintenance is to take corresponding repair and maintenance measures through the analysis of inspection results, extend the service life of the track, and ensure the safe operation of the railway.

[0003] Traditional railway track inspection and maintenance usually rely on manual inspections, single-device inspection methods, and decentralized maintenance tasks. Although manual inspections can detect obvious defects on the track surface in some cases, due to limited inspection accuracy and efficiency, it is easy to overlook minor cracks, deviations, etc., and there are significant time and labor costs in large-scale track inspections. Most traditional track inspection devices are designed for a single task. For example, they are only used for measuring the geometric state of the track or only for surface cleaning. The functions of the devices are single, lack integration, and are complex to operate, making it difficult to move autonomously on the track, resulting in operational inconvenience and low work efficiency.

[0004] In addition, in the prior art, the maintenance work of the track is mostly processed through separate cleaning and anti-rust devices. Although these devices can clean the debris and dirt on the track, they often cannot effectively provide anti-rust protection for the track surface after cleaning, and it is difficult to maintain the healthy state of the track for a long time.

[0005] Furthermore, in traditional technologies, track inspection and maintenance are usually carried out separately, making it difficult to form a systematic and automated inspection and maintenance process. Devices with different functions need to be switched in multiple links, and there is no real-time data feedback and monitoring, making it easy to miss some potential problems or fail to timely detect the parts that need repair.

[0006] Therefore, the present invention proposes a mobile railway track inspection and maintenance device to solve the deficiencies of the prior art. Summary of the Invention

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0041] Please refer to the attached Figure 1 - attached Figure 9 , the embodiments of the present invention provide a mobile railway track detection and maintenance device, including:

[0048] A data feedback module: The data feedback module is connected to the data processing module and is used to real-time feedback the processed result of the state data of the track to a remote control terminal;

[0049] A control module, which is connected to the data processing module and the drive wheel 3, is used to control the running state of the drive wheel 3 according to the processed track state data, and coordinate and dispatch the detection mechanism 4, the cleaning and rust-removing mechanism 5, and the spraying mechanism 6.

[0050] Specifically, the frame 1 is used to support the whole device. It cooperates with the drive wheel 3 through the guide wheel 2. The drive wheel 3 provides power and the guide wheel 2 ensures the direction, enabling the device to move stably along the track, realizing the autonomous movement of the device on the railway track. The cleaning and rust-removing mechanism 5 is used to remove rust, dirt and debris on the track surface, creating good conditions for subsequent detection. The detection mechanism 4 is used to measure the geometric position parameters of the track, detect vibration information, monitor temperature changes, scan surface geometric defects, detect internal cracks and material damage, realizing the comprehensive acquisition of track state data. The spraying mechanism 6 is used to spray anti-rust agent on the cleaned track surface to form a protective film to inhibit rust. The data processing module is used to effectively process the track state data collected by the detection mechanism 4. The data feedback module is used to timely feedback the track state and maintenance information to the remote control terminal and maintenance personnel. The control module is used to realize the intelligent control and coordinated dispatch of the overall operation of the device. The adjusting mechanism 7 can adjust the position of the detection mechanism 4 to be suitable for the detection of different railway tracks, with stronger versatility.

[0051] Please refer to Appendix Figure 1 Appendix Figure 2 and Appendix Figure 4 As shown in, the detection mechanism 4 includes two mounting brackets 401, which are respectively fixedly connected to the outer sides of both sides of the frame 1. A displacement sensor 402, an acceleration sensor 403, a temperature sensor 404, a laser scanning sensor 405 and a ultrasonic sensor 406 are sequentially installed at the bottom of the mounting bracket 401. The displacement sensor 402, the acceleration sensor 403, the temperature sensor 404, the laser scanning sensor 405 and the ultrasonic sensor 406 are all located directly above the track. The displacement sensor 402, the acceleration sensor 403, the temperature sensor 404, the laser scanning sensor 405 and the ultrasonic sensor 406 output the collected track state data to the data processing module. The displacement sensor 402 is used to measure the geometric position parameters of the track. The acceleration sensor 403 is used to detect the vibration information of the track. The temperature sensor 404 is used to monitor the temperature change of the track. The laser scanning sensor 405 is used to scan the geometric defects on the track surface. The ultrasonic sensor 406 is used to detect internal cracks and material damage of the track.

[0052] Specifically, through the cooperation of the mounting bracket 401 with the displacement sensor 402, acceleration sensor 403, temperature sensor 404, laser scanning sensor 405 and ultrasonic sensor 406, the mounting bracket 401 provides a stable support for each sensor, positioning them directly above the track. The displacement sensor 402 focuses on measuring the geometric position parameters of the track, the acceleration sensor 403 accurately detects the vibration information of the track, the temperature sensor 404 monitors the temperature change of the track in real time, the laser scanning sensor 405 carefully scans the geometric defects on the track surface, and the ultrasonic sensor 406 deeply detects the internal cracks and material damage of the track, achieving accurate acquisition of track status data in all directions and from multiple angles, providing a comprehensive and reliable data basis for the subsequent data processing module to deeply analyze the track condition, helping to timely discover potential problems of the track and ensuring the safe and stable operation of the railway track;

[0053] The displacement sensor 402 is arranged in the front:

[0054] Function: The displacement sensor 402 is used to measure the geometric position parameters of the track, including the elevation, alignment and gauge of the track, which are the basic data of the track status.

[0055] Layout consideration: When the device is moving forward, the track may have slight shaking. Therefore, the displacement sensor 402 needs to capture the macroscopic position change of the track as early as possible to provide reference data. Placing it in the front of the device can ensure that the change of the track position is obtained in the first time, so as to provide accurate reference data for the subsequent sensors.

[0056] The acceleration sensor 403 is arranged closely following the displacement sensor:

[0057] Function: The acceleration sensor 403 is used to detect the vibration spectrum of the track and can effectively identify problems such as train wheel-rail impact and track fastener loosening.

[0058] Layout consideration: The acceleration sensor 402 needs to be closely associated with the dynamic position data of the displacement sensor 402 to exclude the vibration interference during the movement of the device itself. Its position should be immediately after the displacement sensor 402, facilitating sharing the same position reference to ensure that the detected vibration data is consistent with the actual dynamic position of the track. In addition, the acceleration sensor 403 should be as close as possible to the track surface to capture high-frequency vibration signals, so that the subtle vibrations related to the track condition can be captured more accurately.

[0059] The temperature sensor 404 is arranged in the middle:

[0060] Function: The temperature sensor 404 monitors the temperature change of the track and provides track status data related to the temperature difference.

[0061] Layout Consideration: Temperature data is a key interference item in track condition analysis as it can affect the expansion or contraction of the track. Therefore, the temperature sensor 404 should be arranged at the central position of the device. Arranging it in the center can ensure that the temperature sensor 404 receives balanced data from different positions, avoiding local deviations caused by temperature gradients, and thus providing more accurate temperature analysis.

[0062] The laser scanning sensor 405 and the ultrasonic sensor 406 are arranged at the ends:

[0063] Function:

[0064] The laser scanning sensor 405 is used to detect geometric defects on the track surface, such as cracks, wear, etc.

[0065] The ultrasonic sensor 406 is used to detect cracks and material damage inside the track.

[0066] Layout Consideration: These two sensors should be located at the ends of the mounting bracket 401 because their detection functions rely on the precise position and status data provided by the previous sensors (displacement, acceleration, temperature). The laser scanning sensor and the ultrasonic sensor work after these data are corrected, enabling more accurate identification of surface and internal defects. By arranging them at the ends, the laser scanning and ultrasonic sensors can capture the complete status of the track surface and inside in real time during the device's movement.

[0067] Please refer to Appendix Figure 1 , Appendix Figure 2 and Appendix Figure 5 , the cleaning and rust removal mechanism 5 includes a mounting shell 501, the mounting shell 501 is fixedly connected to one side of the bottom of the frame 1 close to the guide wheel 2, a motor 502 is installed on the inner top wall of the mounting shell 501, the output end of the motor 502 is fixedly connected to a first pulley 503, a second pulley 504 is rotatably connected to the inner top wall of the mounting shell 501, the first pulley 503 and the second pulley 504 are connected by a belt 505, the bottom ends of the first pulley 503 and the second pulley 504 both penetrate the bottom of the mounting shell 501 and are fixedly connected to a rotating disk 506, a bottom end of each of the two rotating disks 506 is fixedly connected to an eccentric shaft 507, a cleaning and rust removal disk 508 is installed at the bottom end of the eccentric shaft 507, and the cleaning and rust removal disk 508 is in contact with the outer surface of the track.

[0068] Specifically, through the cooperation of the installation shell 501 with the motor 502, the first pulley 503, the second pulley 504, the belt 505, the rotating disk 506, the eccentric shaft 507, and the cleaning and rust-removing disk 508, the installation shell 501 provides a stable installation space; when the motor 502 starts to operate, its output end drives the first pulley 503 to rotate at a high speed. Through the transmission of the belt 505, the second pulley 504 rotates synchronously. The bottoms of the two pulleys drive the rotating disk 506 to rotate. The eccentric shaft 507 at the bottom of the rotating disk 506 generates an eccentric motion as the rotating disk 506 rotates, thereby driving the cleaning and rust-removing disk 508 to closely fit and continuously rub against the outer surface of the track along a complex trajectory, achieving efficient cleaning of rust, dirt, and debris on the track surface, effectively improving the cleanliness of the track surface, creating good conditions for track detection, and avoiding interference from impurities to the detection results; at the same time, delaying the damage of the track caused by rust and other factors, extending the service life of the track, and ensuring the safety and stability of railway transportation.

[0069] Please refer to the attached Figure 1 and the attached Figure 2 and the attached Figure 3 and the attached Figure 6 As shown in the attached drawings, the spraying mechanism 6 includes a liquid storage tank 601, the liquid storage tank 601 is installed at the rear side of the frame 1, a liquid inlet 602 is installed on one side of the top of the liquid storage tank 601, a fixing frame 604 is fixedly connected to the bottom of the liquid storage tank 601, a peristaltic pump 603 is installed inside the fixing frame 604, the input end of the peristaltic pump 603 is connected to the bottom of the liquid storage tank 601 through a pipeline, and the output end of the peristaltic pump 603 is fixedly connected to a delivery pipe 605. Nozzles 606 are installed at both ends of the delivery pipe 605.

[0070] Specifically, through the cooperation of the liquid storage tank 601 with the liquid inlet 602, the fixing frame 604, the peristaltic pump 603, the delivery pipe 605, and the nozzles 606, the liquid storage tank 601 is used to store the anti-rust agent; the anti-rust agent can be conveniently added into the liquid storage tank 601 from the liquid inlet 602; the fixing frame 604 provides a stable support for the peristaltic pump 603; after the peristaltic pump 603 is started, by using its unique peristaltic method, the anti-rust agent at the bottom of the liquid storage tank 601 is sucked through the pipeline, and then transported to the nozzles 606 at both ends through the delivery pipe 605. The nozzles 606 evenly spray the anti-rust agent on the surface of the cleaned track, achieving precise and uniform coverage of the anti-rust agent on the track surface and forming a dense protective film on the track surface. This protective film effectively prevents corrosive substances such as oxygen and moisture from contacting the track metal, inhibits the generation and development of rust, and further extends the service life of the track; at the same time, it ensures the high efficiency and smoothness of railway transportation and reduces train operation failures caused by track rust problems.

[0071] Please refer to the attached Figure 7, the data processing module includes a signal acquisition unit, a data filtering unit, and an error correction unit. The signal acquisition unit receives the status data of the track. The data filtering unit filters out the noise signals in the status data of the track. The error correction unit corrects and estimates the status data of the track based on the track dynamic model.

[0072] Specifically, through the cooperation of the signal acquisition unit with the data filtering unit and the error correction unit, the signal acquisition unit actively receives the track status data transmitted from the detection mechanism 4. Immediately afterwards, the data filtering unit is activated, and a specific algorithm is used to accurately identify and filter out the noise signals in the received track status data, effectively reducing the interference components in the data. Subsequently, the error correction unit, based on the track dynamic model, deeply analyzes the filtered data, and by comparing with the theoretical data in the model, corrects and estimates the track status data, realizing the conversion of the original, complex, and possibly error- and noise-containing track status data collected by the detection mechanism 4 into accurate, reliable, and data that more conforms to the actual operating conditions of the track. These data provide a solid basis for the control module to make accurate decisions, helping maintenance personnel to more clearly and accurately understand the true state of the track, so as to timely and effectively formulate track maintenance strategies and ensure the safe and stable operation of the railway track.

[0073] Please refer to the appendix Figure 8 , the control module includes a controller, an adjustment unit, and a parameter optimization unit. The controller is used to control the start, stop, and speed adjustment of the driving wheel 3 according to the status data of the track processed by the data processing module. The adjustment unit is used to dynamically adjust the working parameters of the sensor module, the cleaning module, and the spraying device according to different track environments. The parameter optimization unit optimizes the device operation parameters in real time based on the optimal control algorithm.

[0074] Specifically, through the cooperation of the controller with the adjustment unit and the parameter optimization unit, the controller works based on the track status data processed by the data processing module. When the data shows that the track condition is good and suitable for normal operation, the controller controls the driving wheel 3 to rotate at a constant speed. If it is detected that there are problems with the track, the controller flexibly controls the start, stop, and speed adjustment of the driving wheel 3. For example, it reduces the speed or pauses the operation of the device in areas with severe track diseases to ensure the safety and high efficiency of the inspection and maintenance work. The adjustment unit synchronously adjusts the working parameters of the detection mechanism 4, the cleaning and rust removal mechanism 5, and the spraying mechanism 6 according to different track environments, such as areas with humid and rainy weather, sections with strong wind and sand, etc. For example, in a humid environment, it appropriately increases the frequency and intensity of cleaning and rust removal and increases the spraying amount of the anti-rust agent. In a dry and dusty environment, it optimizes the detection sensitivity of the sensor to avoid dust interference. The parameter optimization unit, based on the optimal control algorithm, analyzes the operating data of each item of the device in real time and optimizes the operating parameters of the device in real time. For example, it adjusts the rotation speed of the motor 502, the flow rate of the peristaltic pump 603, etc., to achieve the state of the lowest energy consumption and the highest working efficiency of the device. It realizes the comprehensive, intelligent, and precise control of the operation of the entire mobile railway track inspection and maintenance device, effectively improves the adaptability of the device in different track environments, ensures the accuracy and high efficiency of the inspection and maintenance work, reduces the operating cost of the device, and ultimately ensures that the railway track is always in good condition.

[0075] Please refer to the appendix Figure 9 , the data feedback module includes an alarm device and a wireless communication device. The alarm device is used to send an alarm signal to the maintenance personnel when an abnormal track is detected, and the wireless communication device is used to transmit the status data and maintenance instructions of the track to the remote control terminal.

[0076] Specifically, through the cooperation of the alarm device and the wireless communication device, the alarm device constantly monitors the track status information fed back by the data processing module. Once an abnormal track situation is detected, such as track deformation, severe cracks inside, etc., the alarm device is quickly activated and conveys the abnormal track information to the maintenance personnel intuitively in a timely manner by emitting obvious signals such as sound and light, ensuring that the maintenance personnel can detect the problem immediately. At the same time, the wireless communication device transmits the detailed status data of the track, including various parameters collected by the detection mechanism 4 and the maintenance instructions generated based on these parameters, to the remote control terminal in a stable and efficient wireless transmission manner, realizing the construction of an efficient information communication bridge between the track site and the remote control terminal. It enables the maintenance personnel to obtain the actual condition of the track in a timely and accurate manner regardless of their location, so as to quickly make decisions and arrange maintenance work, greatly improving the timeliness and response speed of track maintenance, reducing track safety hazards, and effectively ensuring the normal order of railway transportation.

[0077] Please refer to the appendix Figure 1 and the appendix Figure 4, the adjusting mechanism 7 includes two connecting rods 701 and two electric telescopic rods 702. The connecting rods 701 are fixedly connected to the top of the mounting frame 401. The two electric telescopic rods 702 are respectively installed on the left and right sides outside the frame 1. The output ends of the two electric telescopic rods 702 are both fixedly connected with connecting plates 704. The connecting plates 704 are fixedly connected with the connecting rods 701. Two guide rods 703 are slidably connected at the internal through holes of the connecting plates 704. One end of the guide rod 703 is fixedly connected to the frame 1.

[0078] Specifically, through the cooperation of the connecting rod 701, the electric telescopic rod 702 and the connecting plate 704, starting the electric telescopic rod 702 can drive the connecting plate 704 to move horizontally, realizing the automatic adjustment of the horizontal position of the detection mechanism 4; through the cooperation of the guide rod 703 and the connecting plate 704, the moving direction is limited, realizing the stable guiding during the movement of the detection mechanism 4.

[0079] Working principle: When the mobile railway track detection and maintenance device works, the guide wheels 2 at the bottom of the front side of the frame 1 cooperate with the drive wheels 3 at the bottom of the rear side. The drive wheels 3 provide power to push the device to move along the track, and the guide wheels 2 ensure the stable moving direction. During the movement, the motor 502 of the cleaning and rust-removing mechanism 5 drives the first pulley 503, and through the belt 505, the second pulley 504 rotates, and then drives the eccentric shaft 507 at the bottom of the rotating disc 506, so that the cleaning and rust-removing disc 508 cleans the rust, dirt and sundries on the track surface, which is beneficial to the subsequent detection accuracy and reliability.

[0080] After the cleaning is completed, the displacement sensor 402 of the detection mechanism 4 measures the geometric position parameters of the track, the acceleration sensor 403 detects the vibration information, the temperature sensor 404 monitors the temperature change, the laser scanning sensor 405 scans the surface geometric defects, and the ultrasonic sensor 406 detects the internal cracks and material damage.

[0081] After the detection is completed, the peristaltic pump 603 of the spraying mechanism 6 sprays the rust inhibitor in the liquid storage tank 601 from the nozzle 606 through the delivery pipe 605, and sprays it on the track surface to form a protective film on the track surface, inhibiting the generation of rust and ensuring the efficient and smooth railway transportation.

[0082] Meanwhile, the wireless communication device of the data feedback module transmits the track status data and maintenance instructions to the remote control terminal, and the warning device sends a warning signal to the maintenance personnel when detecting track anomalies. Each sensor transmits the collected track status data to the data processing module. The signal acquisition unit of the data processing module receives the data, the data filtering unit filters out the noise, and the error correction unit corrects and estimates the data based on the track dynamic model. The controller of the control module controls the start / stop and speed adjustment of the driving wheel 3 according to the processed data. The adjustment unit dynamically adjusts the working parameters of the detection mechanism 4, the cleaning and rust-removing mechanism 5, and the spraying mechanism 6 according to the track environment, and the parameter optimization unit optimizes the device operation parameters in real time based on the optimal control algorithm.

[0083] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
