Construction engineering survey is an activity that analyzes and evaluates the geological and geographical environmental characteristics and geotechnical engineering conditions of the construction site according to the requirements of the construction project, and prepares construction engineering survey documents. The wall crack detection device is an auxiliary device for detecting cracks in the exterior walls during construction engineering surveys. Wall cracks affect the aesthetics of the building's exterior and also pose potential safety risks to the building's structural safety. Crack detectors are usually used to detect wall cracks.

For example, a wall crack detection device disclosed in the utility model with authorization announcement number CN219994860U drives the moving block up and down by rotating the lifting screw, thereby adjusting the detection height of the crack detector, and drives the measuring block to move left and right by adjusting the rotation of the screw, thereby ensuring that the device can perform all-round detection of walls at high and low places.

The first servo motor 3 is controlled to drive the first threaded rod 5 to rotate. The rotation of the first threaded rod 5 drives the lifting block 22 to move up and down along the first threaded rod 5, thereby adjusting the height of the crack detector body 4. The second servo motor 24 is controlled to drive the third threaded rod 25 to rotate. The rotation of the third threaded rod 25 drives the measuring block to move left and right along the third threaded rod 25, thereby adjusting the left and right position of the crack detector body 4. After completing the position adjustment of the crack detector body 4, the output end of the electric telescopic rod 7 is controlled to extend to drive the anti-skid plate 8 to move downward until the bottom surface of the anti-skid plate 8 is close to the ground, so that the position of the crack detector body 4 can be fixed.

The rotation of the first threaded rod 5 simultaneously drives the second bevel gear 16 to rotate, the rotation of the second bevel gear 16 drives the first bevel gear 15 to rotate, the rotation of the first bevel gear 15 drives the second threaded rod 13 to rotate, the limit plate 17 can prevent the threaded sleeve 12 from rotating when the second threaded rod 13 rotates, the rotation of the second threaded rod 13 drives the threaded sleeve 12 to move outward, the movement of the threaded sleeve 12 drives the connecting block 11 and the electric telescopic rod 7 to move outward, thereby increasing the distribution area of the anti-slip plate 8 on the ground, lowering the center of gravity of the device, and improving the stability of the device.

When the first threaded rod 5 rotates, it drives the transmission gear 18 to rotate. The rotation of the transmission gear 18 drives the rack 9 to move outward at the same time. The outward movement of the rack 9 drives the second universal wheel 10 to move outward at the same time. The simultaneous outward movement of the second universal wheel 10 can further increase the distribution area of the device on the ground and improve the stability of the device.
