Therefore, this paper will not be repeated here.

[0033] Through the above structure, the working principle of the steel structure flaw detection device provided by the present application is as follows:

[0034] Firstly, the steel structure to be detected is horizontally placed between the two clamping seats 7, so that one end of the steel structure abuts against the clamping groove 9 on the left clamping seat 7, and then the electric telescopic rod one 4 is started to extend and run, so as to push the shaft seat 5 and the right clamping seat 7 to move leftwards, so that the two clamping seats 7 approach each other, and then the steel structure is clamped firmly through the anti-skid lines on the clamping groove 9 and the inner wall thereof.

[0035] After the steel structure is clamped and fixed, the motor 8 is started in forward rotation, the output shaft drives the rotating shaft 6 to rotate forward, so that the clamp seat 7 and the clamped steel structure rotate around the axis of the rotating shaft 6, at the same time, the main pulley 17 at the left end of the rotating shaft 6 rotates, drives the auxiliary pulley 18 to rotate through the belt 19, and then drives the lead screw 13 to rotate. Since the moving seat 14 is threadedly sleeved on the lead screw 13 and is limited by the sliding guide of the guide cross bar 20, the rotation of the lead screw 13 drives the moving seat 14 to move horizontally to the right along the lead screw 13 in a straight line. The second electric telescopic rod 15, the assembly plate 16, the ultrasonic flaw detector 11 and the booster air pump 21 are driven by the moving seat 14 to move horizontally to the right, and the second electric telescopic rod 15 can be controlled to extend or contract as needed to adjust the height position of the ultrasonic flaw detector 11 and the booster air pump 21, so that the air jet pipe 22 on the booster air pump 21 is close to the surface of the steel structure. The booster air pump 21 is started, the booster air is sprayed from the air jet pipe 22 to the surface of the steel structure, and then the clamped and fixed steel structure is rotated to cooperate with the horizontal linear movement of the booster air pump 21, so that the dust and impurities on the surface of the steel structure can be effectively removed to ensure the accuracy of the subsequent flaw detection of the steel structure.

[0036] After the surface of the steel structure is cleaned and the dust is removed, the operation of the booster air pump 21 is stopped, and the motor 8 is controlled to reverse, so that the moving seat 14 moves horizontally to the left along the lead screw 13 in a straight line. The second electric telescopic rod 15, the assembly plate 16, the ultrasonic flaw detector 11 and the booster air pump 21 are driven by the moving seat 14 to move horizontally to the left. When the moving seat 14 drives the second electric telescopic rod 15, the assembly plate 16, the ultrasonic flaw detector 11 and the booster air pump 21 to move to the leftmost end, the motor 8 is controlled to rotate forward again, the moving seat 14 drives the second electric telescopic rod 15, the assembly plate 16, the ultrasonic flaw detector 11 and the booster air pump 21 to move to the right in a straight line again. The second electric telescopic rod 15 can be controlled to extend or contract as needed to adjust the height position of the ultrasonic flaw detector 11 and the booster air pump 21, so that the non-contact probe 12 is close to the surface of the steel structure. The ultrasonic flaw detector 11 is powered on, and the non-contact probe 12 can be used to detect the defects on and in the surface of the steel structure. The ultrasonic flaw detector 11 detects the change and analyzes and processes it to judge the quality of the steel structure. The clamped and fixed steel structure is rotated to cooperate with the horizontal movement of the ultrasonic flaw detector 11, so that the steel structure can be effectively detected.
