Description

Technical Field

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

[0002] In the production process of some light steel building structures, it is often necessary to produce connectors, connecting frames and other components in the factory by welding. These components are used to assemble and connect beams, columns and other components. Since the raw materials of these components are relatively thin, the requirements for welding quality are high. Therefore, their welds need to be inspected.

[0003] The existing ultrasonic detection device for welds of building steel structures usually has a relatively simple structure for buffering and protecting the flaw detection mechanism during use, which makes the flaw detection mechanism easily damaged by external impact during daily use, thereby causing certain inconvenience to the user during use.

[0004] The prior art CN217007119U discloses an ultrasonic detection device for welds of building steel structures, which solves the above technical problems by setting up a bottom shell, a connecting column, a sliding rod, a conical connecting piece, a guide block, a buffer shell, a limit rod, an arc plate, a rubber spring column, a cross plate, a rubber block, a slot, a threaded rod, a limit block, an extension tube, a controller, a shell and a limit seat. However, when the above device is used, the steel structure is positioned and the weld detection is performed on it. The steel structure has different shapes and the weld positions on it are also different. It is impossible to achieve all-round detection. It is necessary to repeatedly adjust the clamping position of the steel structure to control the detection orientation of the weld, resulting in low detection efficiency. For this reason, we propose a steel structure weld detection device. Utility Model Content
