Description

Technical Field

[0001] The present invention relates to the technical field of building steel structure detection, and in particular to a building steel structure ultrasonic detection device and method. Background Art

[0002] Ultrasonic testing of building steel structures is a method that uses the propagation characteristics of ultrasonic waves in materials to detect internal defects in steel structures. In building steel structures, common defects include cracks, pores, slag inclusions, and lack of fusion. Cracks are gaps formed by local rupture of the heat-affected zone of the material during welding; pores are holes formed by the metal absorbing too much gas or producing too much gas during welding; slag inclusions are caused by the presence of slag or other non-metallic inclusions in the weld; and lack of fusion is caused by the two layers of metal not being fused or thoroughly welded together during welding. Ultrasonic testing devices can detect defects such as cracks, pores, slag inclusions, etc. in steel structures, and determine the location, size, and shape of the defects.

[0003] Most existing ultrasonic detection devices fix steel structures with bolts. This disassembly and assembly method is slow, resulting in low efficiency of ultrasonic detection of steel structure welds. It is also inconvenient to remove some iron filings or welding slag attached to the surface of the steel structure, which affects the detection accuracy of the ultrasonic detection device.

After clamping and fixing, the electric drive rod 217 is started to drive the lifting tool frame 218 to rise, so that the hollow arc-shaped inflation frame 224 moves to the bottom of the steel structure, and then the bottom of the steel structure is inflated through the hollow arc-shaped inflation frame 224, so that the iron filings and welding slag attached to the outside of the steel structure fall off, and the drive motor 22 is started at the same time. 9, the driving motor 229 drives the rotating push rod 230 to make the tooth block end of the arc-shaped tooth plate 233 above the tooling adjustment frame 234 reciprocate in an arc shape, and the arc-shaped tooth plate 233 drives the hollow arc-shaped air-inflating frame 224 above the bidirectional rotating cylinder 226 to reciprocate horizontally. After cleaning, the servo motor 203 drives the tooling detection frame 202 to flip over and clean the other side. After cleaning, the detection probe 4 on the ultrasonic detector 5 is used to align the steel structure for ultrasonic detection. At the same time, the electric telescopic rod 310 drives the adjustment gear rod 1 309 to move inside the guide track 308, so that The adjusting gear rod 1 309 drives the angle rotating gear 2 316 to rotate, and the angle rotating gear 2 316 drives the bevel gear 1 318 on the rotating cylinder 315, and the bevel gear 1 318 drives the bevel gear 2 320 so that the angle adjusting rod 319 can adjust the longitudinal detection angle of the detection probe 4, and the electric telescopic rod 4 312 drives the adjusting gear rod 2 311 to move in the guide track 308, so that the adjusting gear rod 2 311 drives the angle rotating gear 1 314 to rotate, and the angle rotating gear 1 314 drives the rotating tube 313 to adjust the horizontal angle of the detection probe 4.
