Technical Field

[0001] The present invention relates to the technical field of railway detection, and particularly relates to a rapid detection device for railway engineering diseases and an implementation method thereof. Background Art

[0002] In some railway detection processes, a monitoring device is moved along the railway track, and rail information is collected by a collector, and then potential diseases are detected. The existing monitoring device includes a vehicle bottom plate. Shock absorbers are connected to the four corners of the bottom of the vehicle bottom plate by bolts, and the bottoms of two shock absorbers at the same end of the vehicle bottom plate are connected to the same driven shaft through bearing seats and bearings. Driven track wheels are sleeved on both ends of the circumferential outer wall of the driven shaft. Pressure sensors are connected to both ends of the driven shaft by screws, and springs are respectively connected to the two driven track wheels on the sides where the two pressure sensors are away from each other. This monitoring device does not require staff to operate on site, has high efficiency, saves time and effort, increases the operation time of the high-speed railway track disease monitoring device, reduces the cost of the high-speed railway track disease monitoring device at the same time, is energy-saving and environment-friendly, effectively avoids the phenomenon that the monitoring probe is damaged due to the harsh on-site environment of the high-speed railway track, and improves the stability of the high-speed railway track disease monitoring system.

[0003] The existing monitoring device has the following problems: When passing through the curved part of the railway track, the distance between the collector and the railway track will change, which will affect the accuracy of information collection, and the accuracy of rail information collection is relatively low.

[0004] Based on the above situation, there is an urgent need for a rapid detection device for railway engineering diseases to solve the problem of relatively low accuracy of information collection. Summary of the Invention

[0005] The purpose of the present invention is: For the existing monitoring device, when passing through the curved part of the railway track, the distance between the collector and the railway track will change, which will affect the accuracy of information collection, and the accuracy of rail information collection is relatively low; Therefore, the present application provides a rapid detection device for railway engineering diseases and an implementation method thereof. The implementation of this device and the method solves the problem of relatively low accuracy of information collection.

[0006] The technical solution of the present invention is as follows: A rapid detection device for railway bridge diseases, comprising: A base, installed on the railway track; A monitoring mechanism, installed on the base; A traveling mechanism, installed on the base, and the traveling mechanism includes two traveling wheel assemblies; A deviation correction mechanism, installed on the base and used to independently control each traveling wheel assembly.

[0007] In the existing monitoring device, when passing through the curved part of the railway track, the distance between the collector and the railway track will change, which will affect the accuracy of information collection. The accuracy of information collection on the railway track is relatively low. In this solution, the walking mechanism drives the base and the monitoring mechanism to move along the railway track. By using the deviation correction mechanism to independently control the differential speed of the two walking wheel assemblies respectively, deviation correction can be carried out when the base passes through the curved part of the railway track, so that the monitoring mechanism maintains a preset distance from the railway track, improving the accuracy of information collection and solving the problem of relatively low accuracy of information collection.

[0008] Furthermore, the specific structure of the walking wheel assembly in this solution is not uniquely defined. One feasible solution is that the walking wheel assembly includes a driving wheel and a stepping motor for driving the driving wheel. When adopting this solution, the driving wheel is driven to rotate by the stepping motor, and the rotation speed of the driving wheel can be adjusted more precisely by adjusting the pulse frequency.

[0009] Furthermore, in order to prevent the driving wheel from disengaging from the railway track, one feasible solution is that the walking mechanism further includes a limiting wheel in contact with the side wall of the railway track. When adopting this solution, the limiting effect of the limiting wheel can prevent the driving wheel from disengaging from the railway track.

[0010] Furthermore, the specific structure of the deviation correction mechanism in this solution is not uniquely defined. One feasible solution is that the deviation correction mechanism includes a distance sensor arranged on the side of the railway track. When adopting this solution, the distance between the distance sensor and the railway track is detected, and the differential speed value of the two walking wheel assemblies is feedback-controlled to realize deviation correction.

[0011] Furthermore, in order to facilitate the adjustment of the deviation correction sensitivity, one feasible solution is that the deviation correction mechanism further includes an extension rod slidably connected to the base, and the distance sensor is installed on the extension rod. When adopting this solution, the distance between the distance sensor and the monitoring mechanism is adjusted by the extension rod, thereby adjusting the deviation correction sensitivity.

[0012] Furthermore, the specific structure of the monitoring mechanism in this solution is not uniquely defined. One feasible solution is that the monitoring mechanism includes a camera and an image analysis module electrically connected to the camera. When adopting this solution, the camera takes pictures of the railway track and transmits the image data to the image analysis module, and then the image analysis module identifies the disease information.

[0013] A method for realizing the above-mentioned rapid detection device for railway engineering diseases, characterized in that it is specifically as follows; Step 1, Equipment Installation: Steadily install the base on the railway track to ensure firm contact between the base and the track; install a battery pack inside the base to supply power to the entire device; install the limit wheels on the side wall of the base through the axle seats with bolts so that they contact the side wall of the track, and check the rotational flexibility of the limit wheels to ensure that the driving wheel can be effectively prevented from disengaging from the track; Step 2, Mechanism Debugging: Debug the two walking wheel assemblies of the walking mechanism. Start the stepper motor and test the rotation of the driving wheel to ensure that it can stably drive the device to move along the track; install the distance sensor on the extension rod, and then slidably connect the extension rod to the base. According to the detection requirements, adjust the extension rod and set the distance between the distance sensor and the monitoring mechanism to complete the preliminary setting of the deviation correction sensitivity; Step 3, Monitoring Setting: Install cameras on the base and the extension arm respectively, and electrically connect them to the image analysis module; check the shooting angles of the cameras to ensure that the inner and outer areas of the track can be fully covered, and complete the installation and debugging of the monitoring mechanism; Step 4, Detection Start and Movement: Start the device, drive the driving wheel to rotate through the stepper motor of the walking mechanism, and the driven wheel assists to make the base and the monitoring mechanism move smoothly along the track, and start the railway bridge disease detection work; Step 5, Deviation Correction Process: When the device passes through the curved part of the track, the distance sensor continuously detects the distance between it and the track and feeds the data back to the corresponding control system; the control system generates a differential speed for the stepper motors of the two walking wheel assemblies according to the preset distance standard between the monitoring mechanism and the track; when the device deviates to one side, the control system increases the pulse frequency of the stepper motor of the walking wheel assembly on that side to accelerate its rotation speed, so that the rotation speed of the driving wheel on that side increases, thereby realizing deviation correction, ensuring that the monitoring mechanism maintains a preset distance from the track, and ensuring the accuracy of information collection; Step 6, Information Collection: During the movement of the device, the cameras on the base and the extension arm continuously capture images of the track, and transmit the captured image data to the image analysis module in real time; the image analysis module processes and analyzes the images to identify disease information such as cracks, wear, and deformation on the track surface, and records the relevant data.

[0014] Compared with the existing technology, the beneficial effects of the present invention are: the base and the monitoring mechanism are driven by the traveling mechanism to move along the rail, and the two traveling wheel assemblies are independently controlled by the deviation correction mechanism to generate differential speed, so that the deviation of the base passing through the curved part of the rail can be corrected, so that the monitoring mechanism maintains a preset distance from the rail, thereby improving the accuracy of information collection and solving the problem of low accuracy of information collection; since the traveling wheel assembly includes a driving wheel and a stepper motor for driving the driving wheel, the driving wheel is driven to rotate by the stepper motor, and the rotation speed of the driving wheel can be more accurately adjusted by adjusting the pulse frequency; since the traveling mechanism also includes a limiting wheel in contact with the side wall of the rail, the limiting effect of the limiting wheel can prevent the driving wheel from leaving the rail.

[0018] The features and performance of the present invention will be further described in detail below in conjunction with embodiments.

[0019] Embodiment: Please refer to Figure 1 、 Figure 2 and Figure 3 , a rapid detection device for railway engineering diseases, comprising: A base 1, installed on the railway track 2, and a battery pack 11 is installed inside the base 1; A monitoring mechanism 3, installed on the base 1; A traveling mechanism 4, installed on the base 1, and the traveling mechanism 4 includes two traveling wheel assemblies 41; A deviation correction mechanism 5, installed on the base 1 and used to independently control each traveling wheel assembly 41.

[0020] For existing monitoring devices, when passing through the curved part of the railway track, the distance between the collector and the railway track will change, which will affect the accuracy of information collection. The accuracy of information collection of the railway track is relatively low. In this solution, the traveling mechanism 4 drives the base 1 and the monitoring mechanism 3 to move along the railway track 2. By the deviation correction mechanism 5, the differential speeds of the two traveling wheel assemblies 41 are independently controlled, so that the base 1 can be corrected when passing through the curved part of the railway track 2, so that the monitoring mechanism 3 maintains a preset distance from the railway track 2, improving the accuracy of information collection and solving the problem of relatively low accuracy of information collection.

[0021] Refer to Figure 3 , the specific structure of the traveling wheel assembly 41 is not uniquely defined in this solution. One feasible solution is: the traveling wheel assembly 41 includes a driven wheel 413, a driving wheel 411 and a stepping motor 412 for driving the driving wheel 411. When this solution is adopted, the driving wheel 411 is driven to rotate by the stepping motor 412, and the rotation speed of the driving wheel 411 can be adjusted more precisely by adjusting the pulse frequency.

[0022] Refer to Figure 2, To prevent the driving wheel 411 from disengaging from the rail 2, one feasible solution is as follows: The traveling mechanism 4 further includes a limiting wheel 42 that contacts the side wall of the rail 2. When this solution is adopted, the limiting function of the limiting wheel 42 can prevent the driving wheel 411 from disengaging from the rail 2.

[0023] Preferably, to facilitate the installation and disassembly of the limiting wheel 42, in this embodiment, the limiting wheel 42 is connected to a shaft seat 43, and the shaft seat 43 is detachably installed on the side wall of the base 1 by bolts. When this solution is adopted, the limiting wheel 42 can be installed or disassembled conveniently and quickly.

[0024] Referring to Figure 2 , the specific structure of the deviation rectifying mechanism 5 is not uniquely defined in this solution. One feasible solution is as follows: The deviation rectifying mechanism 5 includes a distance sensor 51 disposed on the side of the rail 2. When this solution is adopted, the distance between the distance sensor 51 and the rail 2 is detected, and the differential speed value of the two traveling wheel assemblies 41 is feedback-controlled to achieve deviation rectification.

[0025] To facilitate the adjustment of the deviation rectifying sensitivity, one feasible solution is as follows: The deviation rectifying mechanism 5 further includes an extension rod 52 slidably connected to the base 1, and the distance sensor 51 is installed on the extension rod 52. When this solution is adopted, the distance between the distance sensor 51 and the monitoring mechanism 3 is adjusted through the extension rod 52, thereby adjusting the deviation rectifying sensitivity.

[0026] Referring to Figure 2 , Figure 4 and Figure 5 , the specific structure of the monitoring mechanism 3 is not uniquely defined in this solution. One feasible solution is as follows: The monitoring mechanism 3 includes a camera 31 and an image analysis module 32 electrically connected to the camera 31. When this solution is adopted, the rail 2 is photographed by the camera 31, and the image data is transmitted to the image analysis module 32, and then the disease information is identified by the image analysis module 32.

[0027] Preferably, to detect the rail 2 more comprehensively, in this embodiment, the monitoring mechanism 3 further includes an extension arm 33 connected to the base 1 and the extension arm 33 extends to the outside of the rail 2. Cameras 31 are installed on both the extension arm 33 and the base 1. When this solution is adopted, the inner and outer sides of the rail 2 are photographed by the cameras 31 on the base 1 and the extension arm 33 respectively.

[0028] To solve the problem of relatively low accuracy of information collection, in this solution, the traveling mechanism 4 drives the base 1 and the monitoring mechanism 3 to move along the rail 2, and the differential speed of the two traveling wheel assemblies 41 is independently controlled by the deviation rectifying mechanism 5, so that deviation rectification can be performed when the base 1 passes through the curved part of the rail 2, so that the monitoring mechanism 3 maintains a preset distance from the rail 2, improving the accuracy of information collection and solving the problem of relatively low accuracy of information collection.

[0029] In order to facilitate the adjustment of the differential speed value between the two traveling wheel assemblies 41, in this solution, since the traveling wheel assembly 41 includes a driving wheel 411 and a stepping motor 412 for driving the driving wheel 411, the driving wheel 411 is driven to rotate by the stepping motor 412, and the rotation speed of the driving wheel 411 can be adjusted more precisely by adjusting the pulse frequency.

[0030] In order to prevent the driving wheel 411 from disengaging from the rail 2, in this solution, since the traveling mechanism 4 further includes a limiting wheel 42 that contacts the side wall of the rail 2, the limiting function of the limiting wheel 42 can prevent the driving wheel 411 from disengaging from the rail 2.

[0031] The following provides an implementation method for a rapid detection device for railway engineering diseases, which is as follows: Device installation: The base 1 is stably installed on the rail 2 to ensure that the base 1 is in firm contact with the rail 2. A battery pack 11 is installed inside the base 1 to supply power to the entire device. The limiting wheel 42 is installed on the side wall of the base 1 through a shaft seat 43 with bolts so that it contacts the side wall of the rail 2, and the rotational flexibility of the limiting wheel 42 is checked to ensure that it can effectively prevent the driving wheel 411 from disengaging from the rail 2. Mechanism debugging: The two traveling wheel assemblies 41 of the traveling mechanism 4 are debugged. The stepping motor 412 is started to test the rotation of the driving wheel 411 to ensure that it can stably drive the device to move along the rail. The distance sensor 51 is installed on the extension rod 52, and then the extension rod 52 is slidably connected to the base 1. According to the detection requirements, the extension rod 52 is adjusted to set the distance between the distance sensor 51 and the monitoring mechanism 3, and the preliminary setting of the deviation correction sensitivity is completed. Monitoring setting: Cameras 31 are respectively installed on the base 1 and the extension arm 33 and electrically connected to the image analysis module 32. The shooting angles of the cameras 31 are checked to ensure that the inner and outer areas of the rail 2 can be fully covered, and the installation and debugging of the monitoring mechanism 3 are completed. Detection stage: Startup and movement: The device is started, and the stepping motor 412 of the traveling mechanism 4 drives the driving wheel 411 to rotate, assisted by the driven wheel 413, so that the base 1 and the monitoring mechanism 3 move smoothly along the rail 2, and the railway bridge disease detection work begins. Deviation correction process: When the device passes through the curved part of the rail 2, the distance sensor 51 continuously detects its distance from the rail 2 and feeds the data back to the control system. The control system controls the stepping motors 412 of the two traveling wheel assemblies 41 to generate a differential speed according to the preset distance standard between the monitoring mechanism 3 and the rail 2. For example, when the device deviates to one side, the control system increases the pulse frequency of the stepping motor 412 of the traveling wheel assembly 41 on that side to accelerate its rotation speed, so that the rotation speed of the driving wheel 411 on that side is increased, thereby realizing deviation correction, ensuring that the monitoring mechanism 3 maintains a preset distance from the rail 2, and guaranteeing the accuracy of information collection. Information collection: During the movement of the device, the cameras 31 on the base 1 and the extension arm 33 continuously capture images of the railway track 2, and transmit the captured image data to the image analysis module 32 in real time. The image analysis module 32 processes and analyzes the images, identifies the disease information such as cracks, wear, and deformation on the surface of the railway track 2, and records the relevant data. III. End stage of detection Data processing: When the device completes the movement of the railway bridge detection section, it stops running. The operator collects the disease information data identified by the image analysis module 32, conducts further sorting and analysis, and generates a railway bridge disease detection report. Equipment recovery: Remove the limit wheel 42, turn off the power of the battery pack 11, remove the device from the railway track 2, clean and inspect the equipment, and prepare for the next detection task.
