When the threaded rod 37 rotates, it drives the threaded block 39 to translate along the threaded rod 37. When the threaded rod 37 translates, it drives the moving column 5 to translate. When the moving column 5 translates, it drives the lifting column 6 to move. When the lifting column 6 moves, it drives the laser detection machine body 8 to detect the cement slab. When the placement height of the cement slab changes, the pull plate 41 is pulled out and the lifting column 6 is adjusted to the required height. After the lifting column 6 drives the laser detection machine body 8 to adjust to the required height, the pull plate 41 is restored to the plug-in state with the lifting column 6 and fixed.

[0025] Working principle: The first step, such as Figure 9 、 Figure 10 and Figure 11 As shown, when it is necessary to perform laser inspection on the bridge cement slab at the bridge construction site, the base plate 1 is placed on the ground, and the stepper motor 36 is started. The stepper motor 36 rotates to drive the threaded rod 37 to rotate. The threaded rod 37 drives the threaded block 39 to translate along the threaded rod 37 when rotating. The threaded rod 37 drives the moving column 5 to translate when it translates. The moving column 5 drives the lifting column 6 to move when it translates. The lifting column 6 drives the laser detection machine body 8 to detect the cement slab when it moves. When the placement height of the cement slab changes, the pull plate 41 is pulled out and the lifting column 6 is adjusted to the required height. After the lifting column 6 drives the laser detection machine body 8 to adjust to the required height, the pull plate 41 is restored to the plug-in state with the lifting column 6 and fixed. Step 2: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the servo motor 11 is started, and the servo motor 11 drives the transmission column 12 to rotate. When the transmission column 12 rotates, it drives the rotating disk 13 to rotate. When the rotating disk 13 rotates, it drives the special-shaped plate 14 to rotate. When the transmission column 12 rotates, it drives the groove block 29 to rotate. The rotation of the groove block 29 drives the clamping bar 30 to rotate. The rotation of the clamping bar 30 drives the crushing block 31 to rotate. The crushing block 31 rotates to break up the mud attached to the side surface of the cement board. When the crushing block 31 is worn and needs to be replaced, the clamping state between the clamping bar 30 and the groove block 29 is released, and the crushing block 31 is removed for replacement. Step 3: Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, when the transmission column 12 drives the rotating disk 13 to rotate, the rotating disk 13 is in contact with the bonding disk 22, and the rotating disk 13 drives the bonding disk 22 to rotate through the friction force when rotating. When the rotating disk 13 drives the special-shaped plate 14 to rotate to the position corresponding to the bonding disk 22, the special-shaped plate 14 is in contact with the bonding disk 22 and pushes the bonding disk 22 to move toward a position away from the rotating disk 13. When the bonding disk 22 moves, it drives the limit frame 19 to move toward the position of the fixed cylinder 16. When the limit frame 19 moves, it drives the starting column 18 to move toward the position of the fixed cylinder 16. When the starting column 18 moves The spring 24 is driven to be compressed, and the special-shaped plate 14 drives the bonding disc 22 to rotate by friction while rotating. When the special-shaped plate 14 rotates to a position away from the bonding disc 22, the compressed spring 24 rebounds and drives the limit frame 19 to reset. When the limit frame 19 resets, it drives the bonding disc 22 to resume the bonding state with the rotating disc 13. When the bonding disc 22 resumes the bonding state with the rotating disc 13, it knocks the rotating disc 13. When the bonding disc 22 rotates, it drives the movable column 20 to rotate. The rotation of the movable column 20 drives the placement disc 21 to rotate. When the placement disc 21 rotates, it drives the brush strip 33 to clean the dust on the surface of the cement board. Step 4: Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, when the limit frame 19 moves toward the position of the fixed cylinder 16, the movable column 20 drives the moving block 34 to move, and the moving block 34 drives the trigger frame 28 to move toward the position of the blocking block 25 when moving. The trigger frame 28 drives the connecting column 26 to move along the connecting bar 15 while moving. When the moving block 34 moves to the position corresponding to the blocking block 25, the moving block 34 fits into the blocking block 25, and the blocking block 25 blocks the moving block 34. When the moving block 34 moves toward the blocking block 25, it is blocked by the blocking block 25. Then the moving block 34 moves toward the position of the half torsion spring 42 in the starting groove of the trigger frame 28. The moving block 34 drives the half torsion spring 42 to be compressed while moving. The moving block 34 expands the cleaning range while moving toward the position of the half torsion spring 42. When the movable column 20 is reset, it drives the trigger frame 28 to reset. Then the blocking block 25 releases the limiting effect on the moving block 34. The half torsion spring 42 rebounds and drives the moving block 34 to reset. When the moving block 34 is reset, it drives the movable column 20 to reset. The reset of the movable column 20 resets the cleaning position of the brush bar 33.
