Description

Technical Field

[0001] The present invention belongs to the technical field of equipment inspection, and in particular to an equipment inspection and maintenance management system integrated with the Internet of Things. Background Art

[0002] In indoor environments, frequently used track systems (such as suspended conveyor chain tracks on factory automated production lines, stacker crane tracks in logistics warehouses, pneumatic tube logistics transmission tracks in hospitals, and automatic hanger tracks in shopping malls) require regular inspections by workers to check track flatness and whether there are any cracks. Laser rangefinders or infrared detection equipment are used for auxiliary diagnosis. Once track deformation, roller jamming, or drive abnormalities are discovered, maintenance measures such as lubrication, bolt tightening, or track replacement are immediately performed to ensure the continuity and safety of material transportation and equipment movement.

[0003] Currently, track inspections are primarily performed manually. Workers carry various inspection tools and inspect each section of track, assessing its condition through visual observation, tapping, listening, and manual measurement. However, the tracks within workshops are often long, with some automated production lines or logistics systems running hundreds of meters long. This makes inspections time-consuming, labor-intensive, and inefficient. In high-intensity, repetitive work environments, manual inspections are prone to missed inspections due to fatigue and are also difficult to accurately identify hidden dangers such as subtle wear, deformation, or loose connectors. Furthermore, inspection data is difficult to digitally record and trace. These issues directly impact the safe operation and maintenance efficiency of the track system. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an IoT-integrated equipment inspection and maintenance management system that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: The IoT-integrated equipment inspection and maintenance management system includes an inspection terminal, an IoT transmission network, and a cloud management platform, and also includes: a wireless network module and a data processing module, both of which are installed on the inspection terminal, wherein a driving wheel is installed at the bottom of the inspection terminal; a mounting frame, connected to the inspection terminal, wherein a device board is fixedly connected to the mounting frame, and a first detection head and a second detection head are respectively installed on the mounting frame and the device board.

[0006] Preferably, a longitudinally arranged shell is fixedly connected to the mounting frame, a vertical pipe is slidably installed in the shell, an exhaust pipe connected thereto is fixedly connected to the top side wall of the vertical pipe, a dust collection device is installed in the exhaust pipe, a brush is provided at the lower end of the vertical pipe, and a lifting part is provided on the vertical pipe for driving the exhaust pipe to move up and down.

[0007] Furthermore, the lifting part includes a first motor fixedly mounted on a mounting frame, a disc fixedly mounted on an output shaft of the first motor, an eccentrically arranged push rod rotatably mounted on the shaft end of the disc, and the other end of the push rod rotatably connected to the outer wall of the vertical tube.

[0008] Furthermore, a U-shaped groove is provided at the lower end of the vertical tube, and the brushes are evenly distributed in the U-shaped groove.

[0009] Furthermore, the outer wall of the housing is provided with an arc groove, an arc plate is slidably installed in the arc groove, the first detection head is installed on the inner wall of the arc plate, and the vertical tube is provided with a reciprocating part that pushes the arc plate to slide back and forth in the arc groove.

[0010] Furthermore, the reciprocating portion includes a rack fixedly mounted on the outer wall of the vertical tube, and a gear meshing with the rack is fixedly mounted on the outer wall of the arc-shaped plate.

[0011] Preferably, a horizontal frame is installed on the inspection terminal, a mounting groove is provided at the bottom of the horizontal frame, and a telescopic part for driving the mounting frame to slide back and forth is provided in the mounting groove.

[0012] Furthermore, the telescopic part includes a second motor fixedly installed in the mounting groove, a reciprocating screw fixedly installed on the output shaft of the second motor, a reciprocating slide slidably installed in the mounting groove is installed on the outer wall of the reciprocating screw, and the mounting frame is connected to the reciprocating slide.

[0013] Furthermore, the inspection terminal is fixedly connected to a rotating shaft, the horizontal frame is rotatably installed on the rotating shaft, the reciprocating slide is rotatably connected to a vertical shaft, the mounting frame is fixedly installed on the vertical shaft, and the device plates are provided with two symmetrical groups, and both groups of the device plates are equipped with symmetrically arranged guide rollers.

[0014] Preferably, an electric spray gun is installed at the bottom of the inspection terminal.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. The present invention drives the inspection terminal to move on the track through the driving wheel, and the first detection head will record the track surface captured in real time. The data processing module will analyze and process the recorded data and transmit the data to the cloud management platform through the wireless network module. Workers can perform maintenance work based on the detection records, thereby automatically completing the track inspection work and facilitating subsequent workers to maintain the track.

[0016] 2. The present invention can drive the lower end of the vertical pipe to move along the upper end surface of the track through the mobile inspection terminal. The vertical pipe will absorb foreign matter on the track surface through the lower end port to prevent the first detection head from being blocked by foreign matter and affecting the detection accuracy. The brush can clean the track surface to improve the efficiency of absorbing foreign matter, make the track surface more tidy, and significantly improve the detection accuracy.

[0017] 3.

[0018] 4. The present invention drives the rack up and down through the vertical tube, and the gear drives the arc plate to slide back and forth in the arc groove, thereby driving the first detection head to swing back and forth along the arc path, thereby significantly improving the detection range of the first detection head and preventing blind spots on the track from being undetected.

[0019] 5. The present invention can also drive the reciprocating screw to rotate through two motors, and the mounting frame can drive the vertical tube, the first detection head and the second detection head to move back and forth along the track surface. On the one hand, it improves the effect of cleaning the track surface, and on the other hand, it can increase the detection range of the first detection head and the second detection head, thereby improving the detection accuracy. On the other hand, it prevents the driving wheel and the bottom of the second detection head from being concave, which leads to the inability to detect track subsidence abnormalities, thereby further improving the detection accuracy of the second detection head.

[0020] 6. The present invention clamps two pairs of guide rollers on both sides of the track. When the track has a bend, the guide rollers can deflect the mounting frame and the vertical pipe on the vertical axis, and the horizontal frame can deflect on the rotating axis, so that the vertical pipe, the first detection head and the second detection head can basically keep moving above the track, so that the entire inspection device can adapt to complex track shapes.

[0021] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0025] Example 1: Reference Figures 1-8The IoT-integrated equipment inspection and maintenance management system includes an inspection terminal 1, an IoT transmission network, and a cloud management platform. The inspection terminal 1 is also equipped with a storage device for storing data. It also includes: a wireless network module 8 for transmitting detection data to the cloud management platform and a data processing module 7 for processing the detection data, both of which are installed on the inspection terminal 1. The wireless network module 8 uses a 5G module (such as Huawei MH5000), and the data processing module 7 is equipped with Jetson AGX Orin and runs the YOLOv5 model to identify cracks. The bottom of the inspection terminal 1 is equipped with a drive wheel 2, and the inspection terminal 1 moves on the track via the drive wheel 2; the mounting frame 3 is connected to the inspection terminal 1, wherein the mounting frame 3 is fixedly connected to the device board 6, and a first detection head 4 and a second detection head 5 are respectively installed on the mounting frame 3 and the device board 6. The first detection head 4 is mainly composed of a visual sampling camera and an infrared sampling camera. The visual sampling camera is used to collect images of the track surface, and the infrared camera is used to detect whether there is abnormal heating in a local area of ​​the track surface after operation. The second detection head 5 can be an infrared distance sensor or a laser rangefinder for detecting distance.

[0026] Specifically, when in use, the inspection terminal 1 will move on the track through the driving wheel 2, and the first detection head 4 will record the photographed track surface in real time and store it in the storage device in the inspection terminal 1, and the data processing module 7 will analyze and process the recorded data. When it is analyzed that the track has cracks or the local position of the track is abnormally hot (for example, the temperature is greater than 70°), it will be recorded through the storage device and the data will be transmitted to the cloud management platform through the wireless network module 8. Workers can perform maintenance work through the detection records, thereby automatically completing the track inspection work and facilitating subsequent workers to maintain the track; similarly, the second detection head 5 will detect the distance between the mounting frame 3 and the top surface of the track in real time. When the distance exceeds the preset value, for example, when the difference between the detected distance and the preset distance is greater than 3mm, the data processing module 7 will analyze the abnormal height difference. At this time, it is judged that the track has obvious subsidence. The data processing module 7 stores the data to the inspection terminal 1, and finally transmits the data to the cloud management platform through the wireless network module 8.

[0027] An electric spray gun 30 is installed at the bottom of the inspection terminal 1. After the data processing module 7 detects abnormal elements on the track, the electric spray gun 30 will be started to spray paint onto the track surface, so that workers can quickly locate the abnormal position of the track.

[0028] Example 2: Reference Figure 5-Figure 7 The IoT-integrated equipment inspection and maintenance management system is basically the same as that in Example 1, but further includes: A longitudinally arranged sleeve 9 is fixedly connected to the above-mentioned mounting frame 3, a vertical pipe 10 is slidably installed in the sleeve 9, an exhaust pipe 11 connected thereto is fixedly connected to the top side wall of the vertical pipe 10, a dust collecting device 12 for sucking foreign matter is installed in the exhaust pipe 11, a brush 14 is provided at the lower end of the vertical pipe 10, and a lifting part is provided on the vertical pipe 10 for driving the exhaust pipe 11 to move up and down.

[0029] Specifically, during use, the mobile inspection terminal 1 can drive the lower end of the vertical pipe 10 to move along the upper end surface of the track. At this time, the dust suction device 12 in the exhaust pipe 11 can suck air into the vertical pipe 10, and the vertical pipe 10 will absorb foreign matter on the surface of the track through the lower end to prevent the first detection head 4 from being blocked by foreign matter and affecting the detection accuracy. The brush 14 can clean the surface of the track to improve the efficiency of sucking foreign matter, make the track surface more tidy, and significantly improve the detection accuracy. During this period, the lifting part can also drive the vertical pipe 10 to rise and fall in the housing 9, and the vertical pipe 10 will drive the brush 14 to indirectly press against the track surface, thereby improving the effect of the brush 14 cleaning the track, so as to make the track surface more tidy, and make subsequent detection more accurate.

[0030] Example 3: Reference Figure 5-Figure 7 The IoT-integrated equipment inspection and maintenance management system is basically the same as that in Example 2, but further includes: The above-mentioned lifting part includes a first motor 15 fixedly mounted on the mounting frame 3, and a disc 16 is fixedly mounted on the output shaft of the first motor 15. An eccentrically arranged push rod 17 is rotatably mounted on the shaft end of the disc 16, and the other end of the push rod 17 is rotatably connected to the outer wall of the vertical pipe 10.

[0031] Specifically, during the inspection, the first motor 15 will drive the disc 16 to rotate, and the disc 16 will drive the vertical pipe 10 to move up and down in the housing 9 through the push rod 17 based on the principle of the crank slider. The vertical pipe 10 will drive the brush 14 to indirectly press against the track surface, thereby improving the effect of the brush 14 in cleaning the track, making the track surface tidier, and making subsequent inspections more accurate.

[0032] A U-shaped groove 13 is provided at the lower end of the vertical pipe 10, and brushes 14 are evenly distributed in the U-shaped groove 13. Therefore, during the inspection, the top of the track is placed in the U-shaped groove 13. The brushes 14 in the U-shaped groove 13 can not only clean the top of the track, but also clean both sides of the track to prevent the two sides of the track from being blocked by foreign objects and affecting the detection accuracy.

[0033] Example 4: Reference Figure 5-Figure 7 The IoT-integrated equipment inspection and maintenance management system is basically the same as that in Example 3, but further includes: The outer wall of the above-mentioned shell 9 is provided with an arc groove 18, and an arc plate 19 is slidably installed in the arc groove 18. The first detection head 4 is installed on the inner wall of the arc plate 19. The number of the first detection heads 4 is 2-5, and they are evenly spaced on the inner wall of the arc plate 19. The vertical tube 10 is provided with a reciprocating part for pushing the arc plate 19 to slide back and forth in the arc groove 18. The reciprocating part includes a rack 20 fixedly installed on the outer wall of the vertical tube 10, and a gear 21 meshing with the rack 20 is fixedly installed on the outer wall of the arc plate 19.

[0034] Specifically, during the inspection process, the arc plate 19 can enable multiple first detection heads 4 to surround the upper end of the track in an arc path, and when the vertical tube 10 is lifted up and down, the vertical tube 10 will also drive the rack 20 to lift up and down, and the rack 20 will drive the gear 21 to rotate back and forth, and the gear 21 will drive the arc plate 19 to slide back and forth in the arc groove 18, thereby driving multiple first detection heads 4 to swing back and forth along the arc path, thereby significantly improving the detection range of the first detection head 4 and preventing blind spots on the track from being undetected.

[0035] Example 5: Reference Figure 1-Figure 3 as well as Figure 5 The IoT-integrated equipment inspection and maintenance management system is basically the same as that in Example 4, but further includes: From actual use, it is found that when the second detection head 5 is too close to the driving wheel 2, when the driving wheel 2 moves to the depression of the track, the second detection head 5 will move downward at the same time, and the data detected by the second detection head 5 is the distance from the second detection head 5 to the depression. This will result in no obvious abnormality in the data detected by the second detection head 5, that is, the detected distance is basically the same as the preset distance. When the distance between the second detection head 5 and the driving wheel 2 is farther, the data detected by the second detection head 5 is the distance from the second detection head 5 to the flat surface of the track, and the detected distance will be shortened. Therefore, in practice, the installation position of the second detection head 5 needs to be far away from the driving wheel 2. To this end, the following improvements are made: A horizontal frame 23 is installed on the above-mentioned inspection terminal 1, and a mounting groove 24 is provided at the bottom of the horizontal frame 23. A telescopic part that drives the mounting frame 3 to slide back and forth is provided in the mounting groove 24. The telescopic part includes a second motor 28 fixedly installed in the mounting groove 24, and a reciprocating screw 29 is fixedly installed on the output shaft of the second motor 28. A reciprocating slide 25 that is slidably installed in the mounting groove 24 is installed on the outer wall of the reciprocating screw 29, and the mounting frame 3 is connected to the reciprocating slide 25.

[0036] Specifically, during the inspection process, the setting of the cross frame 23 can make the second detection head 5 away from the driving wheel 2 to improve the detection accuracy of the second detection head 5, and the second motor 28 can also drive the reciprocating screw 29 to rotate, and the reciprocating screw 29 will drive the reciprocating slide 25 to slide back and forth in the mounting groove 24, and the reciprocating slide 25 will drive the mounting frame 3 to move back and forth along the track surface, and the mounting frame 3 can drive the vertical pipe 10, the first detection head 4 and the second detection head 5 to move back and forth along the track surface, on the one hand, improving the effect of cleaning the track surface, on the other hand, it can improve the detection range of the first detection head 4 and the second detection head 5, thereby improving the detection accuracy, and on the other hand, it prevents the driving wheel 2 and the second detection head 5 from being recessed, which leads to the inability to detect track subsidence abnormalities, thereby further improving the detection accuracy of the second detection head 5.

[0037] The above-mentioned inspection terminal 1 is fixedly connected to a rotating shaft 22, the horizontal frame 23 is rotatably installed on the rotating shaft 22, the reciprocating slide 25 is rotatably connected to a vertical shaft 26, the mounting frame 3 is fixedly installed on the vertical shaft 26, and the device plate 6 is provided with two symmetrical groups, and both groups of device plates 6 are installed with symmetrically arranged guide rollers 27.

[0038] Specifically, during the inspection process, two pairs of guide rollers 27 are respectively clamped on both sides of the track. Therefore, when the track has a bend, the guide rollers 27 can make the mounting frame 3 and the vertical pipe 10 deflect on the vertical axis 26, and the horizontal frame 23 can deflect on the rotating shaft 22, so that the vertical pipe 10, the first detection head 4 and the second detection head 5 can basically keep moving above the track, so that the entire inspection device can adapt to complex track shapes.

[0039] When the present invention is in use, the inspection terminal 1 will move on the track through the driving wheel 2, and the first detection head 4 will record the photographed track surface in real time and store it in the storage device in the inspection terminal 1, and the data processing module 7 will analyze and process the recorded data. When it is analyzed that the track has cracks or the local position of the track is abnormally hot (for example, the temperature is greater than 70 degrees Celsius), it will be recorded through the storage device and the data will be transmitted to the cloud management platform through the wireless network module 8. Workers can perform maintenance work through the detection records, thereby automatically completing the inspection work of the track and facilitating subsequent workers to maintain the track; similarly, the second detection head 5 will detect the distance between the mounting frame 3 and the top surface of the track in real time. When the distance exceeds the preset value, for example, when the difference between the detected distance and the preset distance is greater than 3 mm, the data processing module 7 will analyze the abnormal height difference. At this time, it is judged that the track has obvious subsidence. The data processing module 7 stores the data to the inspection terminal 1, and finally transmits the data to the cloud management platform through the wireless network module 8.

[0040] During the inspection process, the mobile inspection terminal 1 can drive the lower end of the vertical pipe 10 to move along the upper end surface of the track. At this time, the dust suction device 12 in the exhaust pipe 11 can suck air into the vertical pipe 10, and the vertical pipe 10 will absorb foreign matter on the track surface through the lower end port to prevent the first detection head 4 from being blocked by foreign matter and affecting the detection accuracy. The brush 14 can clean the track surface to improve the efficiency of sucking foreign matter, make the track surface more tidy, and significantly improve the detection accuracy. During this period, the first motor 15 will drive the disc 16 to rotate, and the disc 16 will drive the vertical pipe 10 up and down in the housing 9 through the push rod 17 according to the principle of the crank slider. The vertical pipe 10 will drive the brush 14 to indirectly press against the track surface, thereby improving the effect of the brush 14 cleaning the track, so as to make the track surface more tidy, and make subsequent detection more accurate.

[0041] During the inspection process, the arc plate 19 can make multiple first detection heads 4 surround the upper end of the track in an arc path, and when the vertical tube 10 is lifted up and down, the vertical tube 10 will also drive the rack 20 to lift up and down, and the rack 20 will drive the gear 21 to rotate back and forth, and the gear 21 will drive the arc plate 19 to slide back and forth in the arc groove 18, thereby driving multiple first detection heads 4 to swing back and forth along the arc path, thereby significantly improving the detection range of the first detection head 4 and preventing blind spots on the track from being undetected.

[0042] During the inspection process, the setting of the cross frame 23 can make the second detection head 5 away from the driving wheel 2 to improve the detection accuracy of the second detection head 5, and the second motor 28 can also drive the reciprocating screw 29 to rotate, and the reciprocating screw 29 will drive the reciprocating slide 25 to slide back and forth in the mounting groove 24, and the reciprocating slide 25 will drive the mounting frame 3 to move back and forth along the track surface, and the mounting frame 3 can drive the vertical pipe 10, the first detection head 4 and the second detection head 5 to move back and forth along the track surface, on the one hand, improving the effect of cleaning the track surface, on the other hand, it can improve the detection range of the first detection head 4 and the second detection head 5, thereby improving the detection accuracy, and on the other hand, it prevents the driving wheel 2 and the second detection head 5 from being recessed, which leads to the inability to detect track subsidence abnormalities, thereby further improving the detection accuracy of the second detection head 5.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
