Abstract
The utility model relates to a steel board ultrasonic wave detection device which comprises a main crack detection portion and two sets of edge crack detection portions, wherein the main crack detection portion is used for detection the center place of a unit under detection; the two sets of edge crack detection portions are used for detection the edge places of the unit under detection. A probes arranging method of 7 separated layers, 7 longitudinal directions and 7 horizontal directions is adopted in the steel board main crack detection portion, the steel board main crack detection portion is clamped by three groups of probes frames, and therefore 100% longitudinal, horizontal and separated layers detections of a steel board body are achieved. A probes arranging method shaped like a Chinese character 'pin' of 3 separate layers, 3 longitudinal directions and 3 horizontal directions is adopted in the each edge crack detection portion, and therefore 100% longitudinal, horizontal and separated layers detections of a steel board edge are achieved. Meanwhile, due to the fact that a dislocation of 5-10 millimeters is arranged between the probes, 15% mutual covering between the probes is guaranteed. According to the steel board ultrasonic wave detection device, ultrasonic probes are placed reasonably, and therefore the 100% covering detection of the steel board with a width less than 2.3 meters is achieved with the merely 39 ultrasonic probes. Meanwhile, cost is saved and detection rate is improved.
