Abstract
A modular wheeled mobile ultrasonic structure detection apparatus is disclosed, including a mobile detection platform, at least one ultrasonic detection roller, at least one ultrasonic sensor, and a steering balance mechanism including a connecting arm and at least one balancing apparatus; the balancing apparatus includes a balancing cylinder hinged to the connecting arm, a balancing spring provided in the balancing cylinder, and a steering linkage hinged to the mobile detection platform, a piston being connected to one end of the steering linkage away from the mobile detection platform and the balancing spring being in contact with the piston; and the piston can move along a length direction of the balancing cylinder and thereby define a direction of the steering linkage. When the structure surface fluctuates, bends, or turns, the mobile detection platform can rotate relative to the connecting arm to change the moving posture to adapt to various complex detection conditions. A mobile carrier can pull the detection apparatus in a moving state to realize the non-contact continuous acquisition of ultrasonic waves between the ultrasonic sensor and the structure surface.
