Description

Technical Field

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

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient.

[0003] As the service life of bridges increases, cracks may appear on bridges due to various reasons. The cracks may affect the safety of bridges. Therefore, it is necessary to regularly inspect bridges for cracks. For example, in the prior art, announcement number CN221056360U discloses a bridge crack detection device, which pushes a support plate to make the roller roll along the bridge deck. At this time, the cracks on the bridge deck are photographed by a camera microscope probe, and personnel can observe them through a comprehensive crack defect tester. The drive assembly can drive the left and right rotating rods to rotate simultaneously and oppositely. Since the rack is meshed with the drive gear, the driving gear will drive the lifting cylinder to slide along the limiting slide groove when it rotates, so as to adjust the height of the camera microscope probe. Although the prior art can photograph the cracks on the bridge deck by moving the camera microscope probe, it fails to mark the crack positions, thereby affecting the repair personnel's rapid positioning of the repair points.

[0004] Therefore, those skilled in the art have proposed a bridge crack detection device to solve the problems raised in the above background. Utility Model Content
