Detailed implementation mode
[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation mode:
[0024] As Figure 1 shown, the present utility model provides a non-destructive testing device for steel structure welds, including an inspection table 1. A fixing mechanism 2 is arranged in the middle of the top of the inspection table 1. A moving groove 3 is opened on one side of the top of the inspection table 1 close to the fixing mechanism 2. The middle side of the right end of the inspection table 1 is fixedly connected with an L-shaped plate 4.

[0025] The fixing mechanism 2, the moving groove 3, the L-shaped plate 4, the driving mechanism 5, the detection component 6, the connecting plate 7, the weld detector 8 and the limiting slide rail 9 are arranged. By operating the fixing mechanism 2, the left and right ends of the tubular steel structure can be positioned and fixed, so as to facilitate the positioning and lifting of the two ends of the tubular steel structure. Then, by operating the driving mechanism 5, the detection component 6 can be driven to move along the outer wall of the tubular steel structure, and the weld detector 8 is started for non-destructive testing, automatically detecting the holes appearing in the weld, and improving the detection efficiency and effect.
[0026] As Figure 2As shown in the figure, the utility model provides a technical solution for a non-destructive testing device for steel structure welds: The fixing mechanism 2 includes two support columns 21. At the top of each of the two support columns 21, a U-shaped bracket 22 is fixedly connected. Connecting rods 23 are respectively arranged through the front and rear sides in the vertical direction of the two U-shaped brackets 22. Clamping assemblies 24 are arranged on the opposite sides of the front and rear two connecting rods 23. Return springs 25 are sleeved on the outer walls of the front and rear two connecting rods 23. The ends of the left and right two connecting rods 23 far from the clamping assemblies 24 are fixedly connected with fixing plates 26. In the middle of the ends of the front and rear two fixing plates 26 away from each other, handles 27 are fixedly connected.

The ends of the return springs 25 far from the U-shaped brackets 22 are fixedly connected to the surfaces of the fixing plates 26. By pulling the fixing plates 26, the front and rear two clamping assemblies 24 are driven to expand outwards to clamp the outer wall of the tubular steel structure, and then the elastic force of the return springs 25 is used to fix the tubular steel structure, completing the lifting of both ends of the tubular steel structure.
[0027] As Figure 3 shown in the figure, the utility model provides a technical solution for a non-destructive testing device for steel structure welds: The clamping assembly 24 includes an arc-shaped clamping plate 241.

A rubber convex pad 243 is arranged on the inner wall of the arc-shaped clamping plate 241. The middle side of the outer wall of the arc-shaped clamping plate 241 is fixedly connected to the end of the connecting rod 23 far from the fixing plate 26. The outer wall of the tubular steel structure is positioned by the positioning foot pads 242, so that the rubber convex pad 243 presses and fits the surface of the tubular steel structure.
[0028] As Figure 4As shown in the figure, the utility model provides a technical solution for a non-destructive testing device for steel structure welds: The driving mechanism 5 includes a driving motor 51. The output shaft of the driving motor 51 is fixedly connected with a lead screw 52. The outer wall of the left end of the lead screw 52 is rotatably connected with a bearing 53. A moving block 54 is threadedly connected to the outer wall of the lead screw 52. The top of the moving block 54 is fixedly connected with a cross plate 55. The front and rear ends of the cross plate 55 are respectively fixedly connected with limit blocks 56. By driving the lead screw 52 to rotate through the driving motor 51, the detection component 6 is driven to move through the moving block 54. The detection component 6 includes a fixed sleeve 61 and a mounting plate 62. The middle side of the inner wall of the fixed sleeve 61 is fixedly connected with a mounting ring 63. Four probes 64 are fixedly connected in an annular array on the inner wall of the mounting ring 63. By arranging the probes 64 inside the fixed sleeve 61, the outer wall of the tubular steel structure can be automatically detected without damage when the fixed sleeve 61 moves. The connection ends of the four probes 64 are electrically connected to the receiving end of the weld detector 8. The bottom of the mounting plate 62 is fixedly connected with the top of the cross plate 55. The left side of the outer wall of the lead screw 52 penetrates to the left side inside the moving groove 3. The left end of the bearing 53 is fixedly connected with the left end inner wall of the moving groove 3.
[0029] As Figure 5 shown in the figure, the utility model provides a technical solution for a non-destructive testing device for steel structure welds: The inner wall of the limit slide rail 9 is slidably connected with the outer wall of the limit block 56. By sliding the limit block 56 on the inner wall of the limit slide rail 9, the moving track of the detection component 6 on the moving groove 3 is restricted.
[0030] Next, specifically describe the working principle of the non-destructive testing device for steel structure welds.
[0031] As Figures 1-5As shown in the figure, when using the device, first, pass both ends of the tubular steel structure through the inside of the fixed sleeve 61, and pull the front and rear fixing plates 26 outward through the handle 27, so that the clamping assembly 24 is driven to move by the connecting rod 23, thereby stretching the return spring 25, so that the front and rear clamping assemblies 24 are expanded and displaced. Subsequently, the outer walls of both ends of the tubular steel structure are clamped into the inside of the front and rear arc-shaped clamping plates 241, the surface of the positioning foot pad 242 positions the pipe wall, so that the rubber convex pad 243 presses and fits the surface of the pipe wall. Subsequently, release the force applied to the front and rear fixing plates 26, and use the reset contraction of the return spring 25 to drive the front and rear clamping assemblies 24 to contract inward through the connecting rod 23, thereby clamping and fixing the tubular steel structure, so as to complete the autonomous lifting work of the tubular steel structure. Then, operate the control panel 10 to start the drive motor 51 and at the same time turn on the weld detector 8 with the model CT-350. The output shaft of the drive motor 51 drives the lead screw 52 to rotate, so that the moving block 54 drives the cross plate 55 along the outer wall of the lead screw 52 to slide along the inside of the limit rail 9 through the limit block 56, thereby restricting the movement track of the detection assembly 6, so that the moving block 54 drives the fixed sleeve 61 to move along the outside of the tubular steel structure. During the movement, the weld detector 8 controls the probe 64 to perform non-destructive detection on the tubular steel structure, automatically detecting the holes appearing in the weld, improving the detection efficiency and effect, and thus realizing the complete weld detection.
[0032] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements that do not depart from the spirit of the present invention are all within the protection scope of the present invention.
