Technical Field

[0001] The utility model relates to the technical field of bridge detection, in particular to a crack detection device used in bridge engineering. Background Art

[0002] A bridge generally refers to a structure built on rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. After the bridge is put into use, cracks will appear.

It is impossible to perform independent detection on a higher bridge, and the usability is poor. In view of the above problems, the present application designs a crack detection device for bridge engineering. Utility Model Content
