Description

Technical Field

[0001] The utility model relates to the field of bridge detection, in particular to a bridge detection device with an adjustment function. Background Art

[0002] A bridge generally refers to a structure erected on rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geology, or to meet other transportation needs to make passage more convenient. A bridge is generally composed of an upper structure, a lower structure, a support, and ancillary structures. The upper structure, also known as the bridge span structure, is the main structure for crossing obstacles. The lower structure includes abutments, piers, and foundations. Bridges often deform under the influence of external factors, leading to cracks or even damage, so bridges need to be regularly inspected for safety. When inspecting whether a bridge has cracks, some cracks are not easy to observe with the naked eye, so high-definition probes are needed for observation. The current detection method is mostly to scan the bridge with a handheld probe. During the scanning process, the probe height is not easy to control, and the probe imaging is blurred, which affects the detection of bridge cracks. To this end, we propose a bridge detection device with an adjustment function to solve the above problems. Utility Model Content
