This allows the cleaning column to have a buffer distance when it contacts the concrete surface, preventing damage to the concrete surface. Then, the spring applies pressure to the support plate, making the cleaning column fit more closely to the concrete surface and quickly cleaning the loose soil on the concrete surface, thus revealing the surface cracks.

[0024] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0025] This application discloses a device for detecting cracks and defects on the surface of concrete. For example... Figure 1 As shown, Figure 1 As shown, the device includes a pulley 1, with the side of the pulley 1 rotatably mounted on the lower end of a pulley rod 2. The upper end of the pulley rod 2 is fixedly mounted on the lower surface of a first base plate 3. A hydraulic pump 4 is fixedly mounted on the upper surface of the first base plate 3. A telescopic column 5 is slidably mounted on the upper surface of the hydraulic pump 4. A right-angle rod 6 is fixedly mounted on the upper end of the telescopic column 5. A moving block 10 is fixedly mounted on the right side end of the right-angle rod 6. The device can be moved to a suitable position by means of the pulley 1. Then, the hydraulic pump 4 is started to drive the telescopic column 5 to move up and down, allowing the cleaning column 14 to grind concrete surfaces at different heights. The upper surface of the moving block 10 is slidably mounted on the outer circumference of a track column 9. The upper end of the track column 9 is fixedly mounted on the lower surface of a top plate 8. A square steel pipe 7 is fixedly mounted on the lower surface of the top plate 8. The movement trajectory of the moving block 10 is controlled by the track column 9, and the movement is prevented from deviating and causing the cleaning column 14 to shake, thus damaging the concrete surface.

[0026] Please see Figure 1 A square steel pipe 7 is fixedly installed on the upper surface of the first base plate 3. A movable block 10 is slidably installed on the inner wall of the square steel pipe 7. A first cylindrical rod 20 is fixedly installed on the side of the movable block 10. One end of the first cylindrical rod 20 is fixedly installed on the side of the movable block 10. A second cylindrical rod 21 is fixedly installed on the side of the movable block 10. A spring 22 is slidably installed on the outer circumference of the second cylindrical rod 21. One left end of the spring 22 is fixedly installed on the side of the movable block 10, and one right end of the spring 22 is fixedly installed on the support plate 26. The first cylindrical rod 20 allows the support plate 26 to move along a predetermined trajectory when it approaches the concrete surface, leaving a buffer distance when the cleaning column 14 contacts the concrete surface. The spring 22 applies pressure to the support plate 26, making the cleaning column 14 fit more closely to the concrete surface for grinding.

[0027] Please see Figure 1 A support plate 26 is fixedly installed at one right end of the first cylindrical rod 20. A fixed frame 12 is fixedly installed on the upper surface of the support plate 26. A telescopic plate 16 is slidably installed on the side of the fixed frame 12. A collection box 13 is fixedly installed on the side of the fixed frame 12. The support plate 26 provides support for the fixed frame 12. The fixed frame 12 prevents dust generated during grinding from flying around. The collection box 13 collects the generated dust to prevent it from affecting the surrounding environment.

[0028] Please see Figure 2 An air pump 11 is fixedly installed on the upper surface of the support plate 26, and an air pipe 18 is fixedly installed on the side of the air pump 11. The air pipe 18 is fixedly installed on the side of the air distribution plate 25 through the adapter block 19. The side of the air distribution plate 25 is fixedly installed on the side of the fixed frame 12. The air pump 11 provides air pressure to the inner side of the fixed frame 12, blowing away the generated dust, which is then collected into the collection box 13 through the holes on the side of the fixed frame 12. The air distribution plate 25 makes the air pressure more evenly distributed, collects dust more thoroughly, and prevents dust from splashing and affecting the surrounding working environment.

[0029] Please see Figure 2A second base plate 17 is fixedly installed on the right side of the support plate 26. A fixing frame 12 is fixedly installed on the upper surface of the second base plate 17. A cleaning column 14 is rotatably installed on the lower surface of the second base plate 17 via a cylindrical rod. A first pulley group 15 is rotatably installed at the lower end of the cleaning column 14 via a cylindrical rod. A motor 24 is rotatably installed at one end of the first pulley group 15. The upper surface of the motor 24 is fixedly installed on the lower surface of the support plate 26. A second pulley group 23 is rotatably installed on the first pulley group 15 via a cylindrical rod. The motor 24 drives the first pulley group 15 to rotate, providing rotational force to the cleaning column 14. Then, the force is transmitted to the other cleaning columns 14 through the second pulley group 23. At the same time, the concrete surface is ground and cleaned, making the cleaning work more efficient and facilitating the subsequent detection of cracks and defects on the concrete surface.

[0030] The implementation principle of the concrete surface crack defect detection device in this application embodiment is as follows: During use, the device is moved to a suitable position via pulley 1, and then the moving device brings the grinding rod 14 close to the concrete surface. Upon approaching, the first cylindrical rod 20 provides a buffer to prevent damage to the concrete surface. Then, pressure is applied by spring 22 to make the cleaning rod 14 fit more closely to the concrete surface. Next, the motor 24 and air pump 11 are started, causing the motor 24 to drive the cleaning rod 14 to rotate and grind via the first pulley group 15 and the second pulley group 23. Finally, the telescopic plate 16 prevents… Dust flies out and is collected into the collection box 13 by the air pressure of the air pump 11. After the concrete surface is ground, the hydraulic pump 4 drives the telescopic column 5 to extend, which moves the moving block 10 upward, so that the cleaning column moves upward and the concrete surface above is ground again. After grinding, the motor 24 is turned off and the air pump 11 is turned off. The hydraulic pump 4 is started to shorten the telescopic column 5, so that the moving block 10 moves downward and the whole device is reset, so that the concrete surface is cleaned and subsequent inspection work can be carried out smoothly, avoiding the influence of excessive dust on the surface judgment.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
