[0031] Specifically, the translation screw 5 is in threaded connection with the sliding seat one 6, and the sliding seat one 6 is in sliding connection with the translation sliding seat 2, which has the advantage that the translation motor 4 is started, and the translation motor 4 drives the translation screw 5 to rotate, and since the translation screw 5 is in threaded connection with the sliding seat one 6, the sliding seat one 6 will slide along the track of the translation sliding seat 2 under the action of the rotation of the translation screw 5, so that the translation movement of the sliding seat one 6 can be accurately controlled. The position of the sliding seat one 6 can be accurately adjusted by driving the screw to rotate by the motor, so as to drive other components mounted on the sliding seat one 6 to move, thereby providing an accurate position adjustment basis for subsequent comprehensive detection of the steel structure weld, which helps to improve the accuracy and comprehensiveness of the detection.

[0032] Specifically, the horizontal moving screw 11 is in threaded connection with the sliding seat two 12, and the sliding seat two 12 is in sliding connection with the vertical sliding seat 13, which has the advantage that the horizontal moving motor 10 is started, and the output shaft of the horizontal moving motor 10 drives the horizontal moving screw 11 to rotate, and then the sliding seat two 12 slides horizontally along the track of the vertical sliding seat 13 under the action of the horizontal moving screw 11, so that the horizontal accurate movement of the sliding seat two 12 can be realized, which further enriches the movement dimension of the detection device. By controlling the operation of the horizontal moving motor 10, the horizontal position of the sliding seat two 12 can be flexibly adjusted, so that the vertical sliding seat 13 and subsequent components such as the vertical motor 15 and the sliding seat three 17 mounted on the sliding seat two 12 can be better aligned with different positions of the steel structure weld, thereby improving the detection capability of the detection device for welds at different positions and enhancing the flexibility and adaptability of the detection.

[0033] Specifically, the vertical screw 16 is in threaded connection with the sliding seat three 17, and the sliding seat three 17 is in sliding connection with the vertical sliding seat 13, which has the advantage that the vertical motor 15 is started, and the vertical motor 15 drives the vertical screw 16 to rotate, and the sliding seat three 17 moves vertically along the track of the vertical sliding seat 13 under the driving of the vertical screw 16, so that the sliding seat three 17 is accurately positioned in the vertical direction, and the limiting frame 18 and the ultrasonic detector body 19 mounted on the sliding seat three 17 can accurately approach or move away from the steel structure weld, thereby meeting the detection requirements of welds at different heights, and the detection probe 22 can be placed at a suitable detection position more accurately, thereby improving the detection accuracy and reliability.

[0034] Embodiment two: as shown in Figures 2-7 an improvement over the previous embodiment.

[0035] Specifically, the profile rack 1 is externally fixedly installed with a sliding seat 21, and the outer surface of the transverse sliding seat 8 is fixedly installed with two sliding seats 6; the other sliding seat 6 is in sliding connection with the sliding seat 21. The advantage is that when the translational sliding seat 2 and the translational lead screw 5 drive the sliding seat 6 to move, the two sliding seats 6 on the outer surface of the transverse sliding seat 8 move synchronously; one of the sliding seats 6 slides along the translational sliding seat 2, and the other sliding seat 6 slides along the sliding seat 21 on the outer surface of the profile rack 1, thereby jointly supporting and guiding the movement of the transverse sliding seat 8. The double-sliding-seat structure provides more stable support and guidance for the transverse sliding seat 8, ensuring the stability of the transverse sliding seat 8 during movement. During detection, the stable transverse sliding seat 8 can ensure the normal operation of the transverse motor 10, the transverse lead screw 11 and other related components installed thereon subsequently, thereby improving the stability and reliability of the entire detection device during movement and reducing detection errors caused by component shaking.

[0036] Specifically, the adjusting assembly 20 includes a mounting ring 2001, the outer surface of the mounting ring 2001 is fixedly installed with a sliding sleeve 2002, the inner surface of the sliding sleeve 2002 is provided with a sliding groove 2003, the inner surface of the sliding sleeve 2002 is fixedly installed with a spring 2004, the other end of the spring 2004 away from the sliding sleeve 2002 is fixedly installed with a moving column 2005, the other end of the moving column 2005 away from the spring 2004 is fixedly installed with a suction cup 2006, and the sliding sleeve 2002 is in sliding connection with the moving column 2005 through the sliding groove 2003. The advantage is that during detection, when the detection probe 22 approaches the steel structure weld, the suction cup 2006 contacts the surface of the steel structure. As the detection device continues to move, if the surface is uneven, the suction cup 2006 will be subjected to a certain pressure. At this time, the moving column 2005 will slide in the sliding groove 2003, and the spring 2004 will be compressed, so that the suction cup 2006 can better fit the surface of the steel structure. The adjusting assembly 20 can automatically adapt to the unevenness of the surface of the steel structure, and through the elastic action of the spring 2004 and the sliding adjustment of the moving column 2005, the suction cup 2006 can always maintain good contact with the surface of the steel structure. This can ensure the stability of the detection probe 22 during detection, avoid shaking or deviation of the detection probe 22 due to uneven surface, and thereby improve the accuracy of the detection result.

[0037] Specifically, the inner surface of the suction cup 2006 is provided with a clamping groove 2007, the inner surface of the clamping groove 2007 is fixedly installed with a magnetic disc 2008, and the adjusting assembly 20 is provided with four identical adjusting assemblies. The advantage is that the magnetic force generated by the magnetic disc 2008 can enhance the adsorption force between the suction cup 2006 and the surface of the steel structure, so that the detection device is more stable during detection and is not easy to displace. The four adjusting assemblies 20 are evenly distributed, providing more balanced support and fixing effect, ensuring that the detection probe 22 always maintains a stable position during detection, and improving the accuracy and reliability of detection.

[0038] Working principle: in use, the whole assembly can be installed on the fixed frame, then the profile frame 1 as the support structure of the whole device, the translation slide 2, the transverse slide 8 and the vertical slide 13 installed thereon constitute a three-dimensional movement system. The translation motor 4 drives the translation screw 5 to rotate, and through the threaded connection drives the slide one 6 to slide on the translation slide 2, realizes the horizontal translation, the transverse motor 10 drives the transverse screw 11 to rotate, makes the slide two 12 slide on the vertical slide 13 transversely, realizes the transverse position adjustment. The vertical motor 15 drives the vertical screw 16 to rotate, lets the slide three 17 move vertically on the vertical slide 13, realizes the vertical direction positioning. Through the coordinated movement of the three directions, the ultrasonic detector body 19 installed on the slide three 17 can be accurately moved to any position of the steel structure weld, the slide seat 21 outside the profile frame 1 is slidably connected with one slide one 6 on the transverse slide 8, and the other slide one 6 slidably connected with the translation slide 2 supports and guides the movement of the transverse slide 8 together, ensures the stability of the transverse movement, the detection probe 22 is installed on the ultrasonic detector body 19 and close to the steel structure weld during detection. The suction cup 2006 in the adjusting assembly 20 contacts the surface of the steel structure, when encountering uneven surface, the moving column 2005 slides in the sliding groove 2003 and compresses the spring 2004, so that the suction cup 2006 is self-adapted to the surface of the steel structure. The magnetic disk 2008 in the suction cup 2006 generates magnetic force by electrification, enhances the adsorption force, and the four adjusting assemblies 20 act together to ensure that the detection probe 22 stably contacts the steel structure weld during detection, and ensure the accuracy of detection.
