Description

Technical Field

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

[0002] Crack detection is a technology used to evaluate the integrity of building structures and materials. It is mainly used to identify and evaluate cracks in materials such as concrete, stone, and brick. Cracks at the bottom of concrete road bridges can be measured by ultrasonic non-destructive testing, and crack detection devices are based on ultrasonic non-destructive testing. This method estimates the depth of the crack by sending ultrasonic waves and measuring the time it takes to pass through the material. In addition, the depth can be manually measured by injecting a specific solution into the crack and observing the color change. The common bridge bottom crack detection devices on the market, if the bridge bottom is high and the human body cannot detect it, other staff members need to use poles to lift the detection head to detect cracks at the high bridge bottom. However, this detection method is more cumbersome and wastes manpower. Sometimes it is necessary to measure the high side walls. At this time, the lifted detection head needs to be adjusted to the detection direction, but the detection direction of the detection head is difficult to adjust and needs to be disassembled first and then re-tied.
