Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction detection, and more specifically, the utility model relates to a flaw detection device. Background Art

[0002] Ultrasonic flaw detection is a method of inspecting part defects by utilizing the characteristics that ultrasonic energy can penetrate deep into metal materials and reflect at the interface edge when passing from one cross-section to another. When the ultrasonic beam passes from the probe on the part surface into the metal interior, reflection waves occur respectively when encountering defects and the bottom surface of the part, and pulse waveforms are formed on the fluorescence screen. The position and size of the defects are judged based on these pulse waveforms. Concrete pipe piles are mainly used to bear the weight of buildings. For example, an ultrasonic flaw detection device for engineering construction detection described in the prior art publication number (CN215493357U) provides power through the connection of a walking motor and a walking wheel belt to enable the device to enter a narrow space. The driving motor drives the lead screw to rotate to translate the T-shaped slider, so that the ultrasonic detector detects the plane to be detected. When detecting a high place, the hydraulic rod vertically jacks up the electric push rod, and then the electric push rod extends to detect the high place. After detection, the position is restored. The anti-collision rod can prevent the ultrasonic detector from being damaged due to too high speed or the existence of obstacles. The support rib plate can support the electric push rod when not in use.

[0003] When the above device is in use, the driving motor drives the lead screw to rotate to translate the T-shaped slider, so that the ultrasonic detector detects the plane to be detected. The support rib plate can support the electric push rod when not in use. This not only solves the problem of inconvenient detection in narrow and high places, liberates the staff, and makes the detection more accurate, but it needs to erect the electric telescopic rod in advance and then move it to the surface of the engineering building. However, after it is erected, the flaw detection device still needs to be moved to the surface of the engineering building, and the operation is relatively inconvenient, thus affecting the convenience of workers for flaw detection of engineering buildings.
