Compared to reinforced concrete structures, they possess unique advantages in terms of height, size, and lightness. Globally, especially in developed countries and regions, steel components have been rationally and widely applied in the field of building engineering.

To ensure welding quality, flaw detection is usually required after welding. However, existing flaw detection devices are not effectively adapted to different welded structures, so improvements are needed. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios. Example 1:
[0023] like Figure 1 , Figure 2 As shown in the figure, this application provides a steel component flaw detection device, including: The detection component 100 is provided with a mounting housing 110 and can be connected to an operation display. The first ultrasonic probe 200 is mounted on the detection assembly 100; The second ultrasonic probe 300 is mounted on the detection assembly 100; The third ultrasonic probe 400 is installed on the detection assembly 100; The limiting mechanism 500 corresponds to the second ultrasonic probe 300 and the third ultrasonic probe 400, respectively. The first ultrasonic probe 200 is positioned between the second ultrasonic probe 300 and the third ultrasonic probe 400. The second ultrasonic probe 300 and the third ultrasonic probe 400 are movable relative to the first ultrasonic probe 200. The second ultrasonic probe 300 and the third ultrasonic probe 400 are each provided with a corresponding adjustment mechanism 600.
[0024] The detection component 100 is connected to a power supply and an operation display. In use, the detection component 100 is held handheld to inspect the weld. The mounting housing 110 is used to mount the first ultrasonic probe 200, the second ultrasonic probe 300, and the third ultrasonic probe 400. The first ultrasonic probe 200, the second ultrasonic probe 300, and the third ultrasonic probe 400 emit ultrasonic waves and perform detection, transmitting the detection data to the operation display. In use, the second ultrasonic probe 300, the first ultrasonic probe 200, and the third ultrasonic probe 400 are arranged sequentially along the weld axis, and sequentially along the weld width. The ultrasonic probe 200 and the third ultrasonic probe 400 are also arranged in sequence, so that the first ultrasonic probe 200 is used to detect the middle position of the weld, and the second ultrasonic probe 300 and the third ultrasonic probe 400 are used to detect the two sides of the weld. The first ultrasonic probe 200, the second ultrasonic probe 300 and the third ultrasonic probe 400 can achieve full coverage of the width direction of the weld. The limiting mechanism 500 is used to target the steel structure on both sides of the weld, improve the stability of the movement of the detection component 100 when it is being detected, and can be adapted to both external and internal corner welds, thus improving the applicability of the detection component 100. Example 2:
[0025] like Figure 2 , Figure 3 As shown, this application embodiment provides a steel component flaw detection device, which, in addition to including the above-mentioned technical features, further includes the following adjustment mechanism 600: The adjusting base 610 is installed and connected to the second ultrasonic probe 300 and the third ultrasonic probe 400 respectively. The adjusting seat 610 is provided with a sliding part 611, and the mounting housing 110 is provided with a sliding groove 120 corresponding to the sliding part 611.
[0026] The adjusting seat 610 is adapted to the slide groove 120 through the sliding part 611 and connected through the sliding pair. The second ultrasonic probe 300 and the third ultrasonic probe 400 are respectively fixedly installed on the corresponding adjusting seats 610. The adjusting seats 610 are respectively located on both sides of the mounting housing 110. The first ultrasonic probe 200 is fixedly installed on the mounting housing 110. Through the relative movement between the adjusting seat 610 and the mounting housing 110, the adjusting seat 610 can be adjusted according to the width of the weld.
[0027] Furthermore, the adjustment mechanism 600 also includes: Rack 620 is mounted on adjusting seat 610; Gear 630 is movably mounted on mounting housing 110 and meshes with rack 620; The worm gear 640 is connected to the gear 630 via a transmission rod; The worm 650 is movably mounted on the mounting housing 110, and the worm 650 cooperates with the worm wheel 640.
[0028] The rack 620 is mounted on the adjusting seat 610 by fasteners such as screws or bolts. The gear 630 is movably mounted on the mounting housing 110. The gear 630 and the worm gear 640 are both connected by a key via a transmission rod. The worm 650 is movably mounted on the mounting housing 110 via a bearing or bushing. One end of the worm 650 extends outside the mounting housing 110 to facilitate the rotation adjustment of the worm 650. Rotating the worm 650 causes the worm gear 640 to rotate. Through the coaxial connection between the worm gear 640 and the gear 630, the gear 630 rotates. The gear 630 meshes with the rack 620, thereby moving the rack 620 and adjusting the adjusting seat 610. Example 3:
[0029] like Figure 2 , Figure 4 As shown, this application embodiment provides a steel component flaw detection device, which, in addition to including the above-mentioned technical features, further includes the limiting mechanism 500 comprising: The limiting seat 510 is hinged to the adjusting seat 610; L-shaped part 520 is placed on limit seat 510; The first elastic element 530 is placed between the limiting seat 510 and the L-shaped element 520; Pull rod 540 is movably connected to L-shaped part 520; Slider 550 is movably connected to pull rod 540; The slide rail 560 is movably connected to the slider 550, and the slide rail 560 is mounted on the adjusting seat 610; The first electromagnet 570 is installed on the slider 550 and the adjusting seat 610 respectively and corresponds to each other.
[0030] The limiting seat 510 and the adjusting seat 610 are hinged together. The ultrasonic probe on the adjusting seat 610 is adjacent to the hinge joint between the limiting seat 510 and the adjusting seat 610. The L-shaped part 520 is connected to the limiting seat 510 through the first elastic element 530. The first elastic element 530 is a spring or other elastic component. The pull rod 540 is hinged between the L-shaped part 520 and the slider 550. The slider 550 is connected to the slide rail 560 through a sliding pair. When the slider 550 moves on the slide rail 560, the pull rod 540 pushes the L-shaped part 520 and transmits the force to the limiting seat 510, thus realizing the relative movement between the limiting seat 510 and the adjusting seat 610. The first electromagnet 570 is fixedly installed on the slider 550 and the adjusting seat 610. When the first electromagnet 570 is energized, it generates an interaction force to control the movement of the slider 550, thereby controlling the relative movement between the limiting seat 510 and the adjusting seat 610.
[0031] Furthermore, the limiting mechanism 500 also includes: Limit block 580 is installed on adjustment seat 610 and corresponds to both sides of slider 550.
[0032] The limiting block 580 can be installed on the limiting mechanism 500 by screws or bolts. The size or installation position of the limiting block 580 determines the travel of the slider 550. One end of the travel of the slider 550 corresponds to a 180° angle between the limiting seat 510 and the adjusting seat 610. By adjusting the limiting block 580, the other end of the travel of the slider 550 can control the limiting seat 510 to rotate clockwise or counterclockwise, which can be adapted to internal corner welds or external corner welds respectively. When there are both flat corner welds and internal or external corner welds, the detection efficiency can be improved. Example 4:
[0033] like Figure 2 , Figure 5 As shown, this application embodiment provides a steel component flaw detection device, which, in addition to the above-mentioned technical features, further includes the following in the mounting housing 110: The movable housing 130 is hinged to the mounting housing 110, and the adjustment mechanism 600 is mounted on the movable housing 130. Locking spring pin 700 is installed on movable housing 130; The mounting housing 110 is provided with a locking groove corresponding to the locking spring pin 700.
[0034] The movable housing 130 and the mounting housing 110 are hinged together by a hinge shaft. The adjusting mechanism 600 and the corresponding ultrasonic probe are mounted on the movable housing 130. When the locking spring pin 700 is engaged with the locking groove, the corresponding ultrasonic probe and the first ultrasonic probe 200 are at the same horizontal level. Through the structure of the movable housing 130, the first ultrasonic probe 200, the second ultrasonic probe 300 and the third ultrasonic probe 400 can detect the arc weld seam between the round tubes. The sliding groove 120 is placed on the movable housing 130.
[0035] Furthermore, the mounting housing 110 also includes: The reset cavity 131 is placed in the movable housing 130; A reset plate 132 is movably placed in a reset cavity 131, wherein the reset cavity 131 is provided with a plug-in groove 133; The second elastic element 134 is placed on both sides of the reset plate 132 and abuts against the reset plate 132; The connector 135 is mounted on the mounting housing 110 and is adapted to the connector slot 133; The second electromagnet 136 is installed on the mounting housing 110 and the movable housing 130 respectively and is adapted to each other.
[0036] The reset cavity 131 is disposed in the movable housing 130. The reset cavity 131 is arc-shaped and its axis coincides with the hinge line between the movable housing 130 and the mounting housing 110. The reset plate 132 can move in the reset cavity 131. The second elastic element 134 is a spring or other elastic component. The reset plate 132 can be reset by the second elastic element 134. When the movable housing 130 is installed, the plug 135 is inserted into the plug groove 133. When the movable housing 130 is in the reset state, the locking spring pin 700 is engaged with the locking groove. When the detection assembly 100 is used to inspect the weld seam on the outer side of the cylindrical steel component, the rotation of the movable housing 130 controlled by the second electromagnet 136 can improve the tightness of the contact between the three ultrasonic probes and the detection position. When the detection assembly 100 is used to inspect the weld seam on the inner side of the cylindrical steel component, the interaction forces of the second electromagnet 136 are controlled to be opposite, causing the movable housing 130 to rotate in the opposite direction. This allows the inspector to apply a small amount of force to maintain the tightness of the contact between the three ultrasonic probes and the detection position. The reset cavity 131, reset plate 132, second elastic element 134, plug-in element 135, and second electromagnet 136 can stably inspect the arc-shaped weld seams on the inner and outer walls of the cylindrical steel component, and can also inspect the arc-shaped weld seams of other steel components. Example 5:
[0037] This application also provides a method for using a steel component flaw detection device, the specific steps of which include: S1. Determine the width of the weld seam. Adjust the second ultrasonic probe 300 and the third ultrasonic probe 400 through the adjustment mechanism 600 so that the three ultrasonic probes can fully cover the width of the weld seam. S2, determine the structure on both sides of the weld seam, and adjust the limiting mechanism 500 so that the limiting mechanism 500 abuts against the steel components on both sides of the weld seam; S3. Before testing, the first ultrasonic probe 200, the second ultrasonic probe 300, and the third ultrasonic probe 400 are calibrated. Then, the weld surface is cleaned, a coupling agent is applied to the weld surface, and the weld is tested by moving the detection component 100.
[0038] The width of the weld seam is adjusted using the adjustment mechanism 600, and the limit seat 510 of the limit mechanism 500 is used to abut against the steel structural members on both sides of the weld seam, thereby improving the stability of the detection component 100 when it moves. With the above structure, it is possible to detect flat corner welds, external corner welds, and internal corner welds of planar structures, as well as external corner welds and internal corner welds of arc-shaped structures.
