Problems solved by technology

[0002] Usually, the bottom of a large storage tank is welded by the melon petals and the top cover. The bottom of the tank is welded by friction stir welding. There are usually two types of welds, longitudinal seams and circular seams. In order to find the defects in the welds, it is necessary to Ultrasonic phased array testing is performed on welds. The traditional testing process is manually operated, and the hand-held detection probe scans and detects along the arc-shaped weld trajectory. It is prone to coupling instability and missed inspection; (2) The bottom of the tank is large and the weld seam is long, manual inspection is difficult and there are safety hazards, the efficiency is extremely low, and it takes a long time; (3) Manual inspection scan speed Unable to accurately control, resulting in deformation of the detection image, making it difficult to analyze defects

Embodiment 1

[0027] Embodiment 1: see figure 1 , 3 , the edge clip 27 is in contact with the inner wall of the top hole, the edge clip 27 is L-shaped, and the connection mode between the edge clip 27 and the slideway straight rod 29 is a sliding connection. The setting of the above structure on the one hand makes this The radian of the guide rail 2 of the device is consistent with the bottom of the storage tank so that the probe 13 is effectively coupled with the weld surface during the scanning process, thereby making the detection result of the bottom of the storage tank more accurate and making this solution more practical. On the one hand, this solution can be applied to the detection of the bottom of the storage tank whose diameter of the hole in the top is in the range of 100mm-400mm, thus making the solution applicable to a wider range.

Embodiment 2

[0028] Embodiment 2: see figure 1 , 4 -6, a driving gear is installed on the upper side of the motor 18, and the driving gear and the gear are all meshed with the rack 6, the probe loading arm mechanism 6 is slidingly connected between the slider seat 8 and the guide rail 2, and the main push rod 23 is connected to the center The connection mode between the hooks 21 is a sliding connection. The above structure makes the device a semi-manual structure. Compared with the traditional pure manual detection method, this solution can further reduce the labor intensity of the detection personnel and improve the detection efficiency.

[0029]The working process of the present invention: when in use, place the bottom of the storage tank in an appropriate position, then pass the umbrella-shaped fixing mechanism 22 through the top middle hole of the bottom of the storage tank, then push the connecting hinge seat 25 upwards, and at the same time rotate upwards The thrust nut 24 is connec...

Abstract

The invention relates to the technical field of ultrasonic phased array detection devices, and especially relates to an ultrasonic phased array detection device. The detection device comprises a detector, the detector comprises guide rails, the guide rails are symmetrically installed on the left side and the right side of the detector, racks are installed on the lower sides of the guide rails, andhandles which are evenly distributed are installed on the upper sides of the guide rails. Rolling wheels are installed on the lower right sides of the guide rails and located between the lower rightsides of the guide rails and the bottom of a storage box, a probe loading arm mechanism is installed in the middle of the upper side of each guide rail, each probe loading arm mechanism comprises positioning rods, a sliding block base, a loading arm connecting block, a compressed spring limit and a loading spring, and the positioning rods are symmetrically installed on the two sides of each probeloading arm mechanism. The sliding block bases are installed on the positioning rods, and the loading arm connecting blocks are installed in the middles of the back surfaces of the sliding block bases. According to the technical scheme, by means of semi-automatic control over the scanning track of a detection probe, an existing detection mode of manually controlling the scanning track is replaced,and then the detection efficiency and accuracy are improved.
