Ultrasonic detection device for building steel structure detection

The utility model discloses an ultrasonic detection device for building steel structure detection, which comprises a bottom plate, the top of the bottom plate is fixedly provided with a fixing sleeve, the inner ring of the fixing sleeve is rotatably connected with a support rod, one end of the support rod far away from the fixing sleeve is fixedly provided with a mounting plate, and one side of the mounting plate is hinged with a lower fixing ring. According to the ultrasonic detection device for detecting the building steel structure, when the steel structure needs to be detected, the steel structure is clamped between the upper fixing ring and the lower fixing ring at the moment, whether the steel structure is attached to the second connecting piece or not is observed, if not, the motor is started, and the first connecting piece is fixedly installed on the inner wall of the lower fixing ring. The output shaft of the motor rotates to drive the rotating rod to rotate, namely the cam can be driven to rotate, t
