Description

Technical Field

[0001] This application relates to the field of bridge pavement crack detection technology, and more specifically, to a device for detecting pavement cracks. Background Technology

[0002] Road surface crack detection equipment is an important tool in road maintenance and infrastructure upkeep. It is mainly used to identify, assess and record damage such as road surface cracks to improve road safety and service life. Modern detection equipment combines a variety of advanced technologies, including optical imaging, laser scanning and artificial intelligence analysis, to complete detection tasks efficiently and accurately.

[0003] In related technologies, to address the issues of the inability to adjust the height of the bottom detection end of the crack detector, its tendency to collide with obstacles during movement, and the relatively large distance between the bottom of the crack detector and the road surface, resulting in low detection accuracy, a patent with publication number CN221684204U provides a bridge pavement crack detection device. This device uses a battery to power the crack detector, touch screen, and motor, ensuring the reliability of the equipment for outdoor use. The touch screen is electrically connected to the crack detector and motor, and can display the detection screen of the crack detector and control the start and stop of the motor, thereby achieving automatic adjustment of the height of the crack detector.

[0004] Although the existing technical solutions mentioned above can achieve the effect of adjusting the height of the crack detector by setting a motor to drive the crack detector to lift, if the crack in the road surface is filled with small stones or blocked by sand and gravel, the crack cannot be accurately detected, which affects the detection accuracy.

[0005] In view of this, we propose a device for detecting road surface cracks. Utility Model Content

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This application discloses a device for detecting road surface cracks, including a moving mechanism 1. The moving mechanism 1 includes a base plate 11. A rotating cylinder 2 is rotatably mounted on the bottom of the base plate 11. A vision camera 21 and an air knife 22 are respectively mounted on both sides of the rotating cylinder 2. The vision camera 21 is used to detect road surface cracks, and the air knife 22 is used to clean the cracks. A drive motor 3 is fixedly mounted on the bottom of the base plate 11. The drive motor 3 is used to drive the rotating cylinder 2 to rotate and complete the alternating work of the vision camera 21 and the air knife 22. A fan 4 is fixedly mounted on the top of the base plate 11. The fan 4 is used to blow air into the inside of the air knife 22.

[0030] When the equipment is in use, the moving mechanism 1 drives the rotating cylinder 2 to move. During the movement, the vision camera 21 detects road surface cracks. The vision camera 21 can be focused to ensure that the road surface cracks can be clearly imaged. When the crack is filled or blocked by small stones, the drive motor 3 drives the rotating cylinder 2 to rotate, so that the air knife 22 rotates and is aligned with the crack. The fan 4 blows air into the inside of the air knife 22, and the airflow blows and cleans the crack through the air knife 22.

[0031] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The output end of the fan 4 is provided with a duct 41. The output end of the drive motor 3 is fixedly provided with a gear A31. A gear B32 is meshed on the outer side of the gear A31. The inner side of the gear B32 is fixedly provided with one side of the rotating cylinder 2. The inner sides of both gear A31 and gear B32 are rotatably provided with the outer side of the support plate A33. A connecting frame 34 is fixedly provided with the top of the support plate A33. A support plate B35 is fixedly provided with one side of the connecting frame 34. The connecting frame 34 is fixedly provided with the bottom of the base plate 11. A protective arc plate 36 is fixedly provided with the inner side of the support plate A33 and the inner side of the support plate B35. The protective arc plate 36 is used to protect the vision camera 21. Fixed shafts 23 are fixedly provided on both sides of the rotating cylinder 2. The outer sides of both fixed shafts 23 are rotatably provided with the inner side of the connecting frame 34. The connecting pipe 211 of the vision camera 21 is fixedly provided with the inner side of the corresponding fixed shaft 23. The connecting line 221 of the air knife 22 is fixedly provided with the inner side of the corresponding fixed shaft 23.

[0032] When cleaning the crack, the drive motor 3 drives the gear A31 to rotate, which in turn drives the gear B32 to rotate. The gear B32 drives the rotating cylinder 2 to rotate, so that the air knife 22 is aligned with the crack. The fan 4 blows air, and the airflow passes through the air duct 41 and the connecting wire 221 and finally blows out from the air knife 22 to clean the crack. The drive motor 3 rotates forward when driving the air knife 22 to replace the vision camera 21 and reverses when driving the vision camera 21 to replace the air knife 22, to prevent the internal wiring from getting tangled and affecting normal use.

[0033] During the cleaning process, the vision camera 21 is rotated to the other side, and the protective arc plate 36 protects the vision camera 21 to prevent small stones from scratching the surface of the vision camera 21 during cleaning, and also to prevent dust from getting on the outside of the vision camera 21.

[0034] The drive motor 3 rotates, which drives gear A31 to rotate, thereby driving gear B32 to rotate. Gear B32 drives the rotating cylinder 2 to rotate, which can also adjust the detection angle of the vision camera 21. The vision camera 21 is connected to the power supply equipment through the connecting pipe 211.

[0035] Reference Figure 1 and Figure 2 A top plate 14 is fixedly installed on the top of the base plate 11. Two support wheels 12 and one universal wheel 13 are installed at the bottom of the base plate 11. A push handle 17 is fixedly installed on the top of the universal wheel 13. A battery casing 5 and a drawer 7 are installed on the top of the base plate 11. A controller 6 is installed on the top of the top plate 14. Support bars 15 are fixedly installed on both sides of the top of the top plate 14. A cover cloth 16 is sleeved on the outside of the two support bars 15. A magnetic slider 161 is fixedly installed at one end of the cover cloth 16.

[0036] When in use, the device can be moved by pushing the handle 17. The battery casing 5 is used to power the drive motor 3, fan 4, controller 6 and vision camera 21. The controller 6 is used to control the detection and display the detection results. When in use, the magnetic slider 161 can be pulled to slide on the two support bars 15, so that the cover cloth 16 can cover the controller 6 to prevent the controller 6 from hitting the stones when the air knife 22 is cleaning the cracks. It can also provide a sunshade effect, preventing the controller 6 from being exposed to the sun while allowing the user to see the contents on the display screen. The drawer 7 is used to store the tools needed for detection.

[0037] In summary, when using the road surface crack detection device disclosed in this application embodiment, the device is moved by pushing the handle 17. During the movement, the road surface crack is detected by the vision camera 21, wherein the vision camera 21 can be focused to ensure that the road surface crack can be clearly imaged.

[0038] When it is necessary to clean the stones inside the crack, the drive motor 3 drives the gear A31 to rotate, which in turn drives the gear B32 to rotate. The gear B32 drives the rotating cylinder 2 to rotate, so that the air knife 22 is aligned with the crack. The blower 4 blows air, and the airflow passes through the air duct 41 and the connecting line 221 and finally blows out from the air knife 22 to clean the crack. Then, the drive motor 3 reverses to drive the gear A31 to rotate, so that the vision camera 21 is rotated to a suitable angle to clean the crack.
