A screw 10 is rotatably installed in the slide rail 2 19, and a stepper motor 20 is installed at one end of the slide rail 2 19. The stepper motor 20 is connected to the screw 10 in the slide rail 2 19, and a slide block 21 is slidably installed on the screw 10 and the slide rail 2 19.

[0025] The detection assembly 1 also includes a nozzle 22, which is mounted on the slide 21. A pump is installed on the material box 12 and is connected to the slide 21 via a hose.

[0026] The detection assembly 1 also includes a distance sensor 23, which is mounted on the end of the nozzle 22 via an annular fastener.

[0027] By using a stepper motor 9 to drive the screw 10 in slide rail 8 to rotate, the slide block 11 slides. During the sliding of slide block 11, a high-definition camera 18 is used to detect the gaps at the bottom of the bridge. During the detection process, a cleaning roller 17 is used to clean the bottom of the bridge, removing dust and debris. By setting a sleeve 15 and a spring in the sleeve 15, the cleaning roller 17 can be kept in close contact with the bottom of the bridge. When a crack is detected, the paint in the material box 12 is sprayed into the crack using a nozzle 22 and a pump to repair the crack.

[0031] Working principle: The detection component 1 is moved to the bottom of the bridge by using the drive component. The height of the detection component 1 is adjusted by the cooperation of the drive component. Then, the screw 10 in the slide rail 8 is rotated by the stepper motor 9, causing the slide 11 to slide. During the sliding of the slide 11, the gaps at the bottom of the bridge are detected by the high-definition camera 18. During the detection, the bottom of the bridge is cleaned by the cleaning roller 17 to remove dust and debris. By setting the sleeve 15 and the spring in the sleeve 15, the cleaning roller 17 can be kept close to the bottom of the bridge. When a crack is detected, the paint in the material box 12 is sprayed into the crack by the nozzle 22 and the pump to repair the crack. The screw 10 in the slide rail 19 is rotated by the stepper motor 20, causing the nozzle 22 to slide for precise repair of the crack.
