[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A non-destructive testing device for cracks in steel cans includes a workbench 1, a rotating assembly, a positioning assembly, and a testing assembly. A support frame 2 is fixedly mounted on the upper surface of the workbench 1. The rotating assembly includes a motor 3, which is fixedly mounted on the upper surface of the support frame 2.

[0027] A rotating rod 4 is fixedly installed at the output end of the motor 3. The rotating rod 4 is rotatably installed inside the support frame 2. A connecting block 5 is fixedly installed at the lower end of the rotating rod 4. A moving rod 6 is slidably installed inside the connecting block 5. A crossbar 7 is slidably installed inside the moving rod 6. A first limiting block 8 is fixedly installed at both ends of the crossbar 7. A second limiting block 9 is installed below each of the two first limiting blocks 8.

[0028] like Figure 1 , Figure 4 and Figure 5 Since the motor 3 is fixed on the upper surface of the support frame 2, the output end of the motor 3 drives the rotating rod 4 to rotate inside the support frame 2. The rotating rod 4 drives the connecting block 5 to rotate, so that the connecting block 5 moves up and down on the outer surface of the moving rod 6, so that the moving rod 6 slides on the outer surface of the crossbar 7, and the crossbar 7 drives the two first limit blocks 8 to rotate.

[0029] The first limiting block 8 and the second limiting block 9 have two positioning bolts 10 on their internal threads, and the steel tank body 11 is slidably disposed between the first limiting block 8 and the second limiting block 9.

[0030] like Figure 4 and Figure 5 Since the main body 11 of the steel tank is located between the first limiting block 8 and the second limiting block 9, the first limiting block 8 is fixed above the second limiting block 9 by the positioning bolt 10.

[0031] The positioning assembly includes threaded rods 12, two threaded rods 12 are respectively threaded at both ends of the support frame 2, one end of each threaded rod 12 is fixedly provided with a rotating block 13, and the other end of each threaded rod 12 is fixedly provided with a clamping block 17, and the two clamping blocks 17 are respectively slidably provided at both ends of the steel tank body 11.

[0032] like Figure 2 and Figure 4 By rotating the rotating block 13, the two threaded rods 12 are threaded into the two ends of the support frame 2, and the two clamping blocks 17 are fixed to the two ends of the steel tank body 11.

[0033] A sliding block 14 is fixedly provided on one side of each of the two rotating blocks 13. A sliding groove 15 is provided at both ends of the support frame 2. The two sliding blocks 14 are slidably disposed inside the two sliding grooves 15 respectively. A magnetic block 16 is fixedly provided at both ends of the support frame 2 and on one side of each of the two rotating blocks 13.

[0034] like Figure 2 and Figure 4 When the two clamping blocks 17 are fixed at both ends of the steel tank body 11, the sliding block 14 slides inside the sliding groove 15, causing the two magnetic blocks 16 to be attracted together, and the two rotating blocks 13 are fixed at both ends of the support frame 2 respectively.

[0035] The detection assembly includes a first scanning probe 18, which is fixedly disposed inside a clamping block 17 and disposed inside the steel tank body 11.

[0036] like Figure 4 and Figure 6 When the first scanning probe 18 is placed inside the steel tank body 11, the inside of the steel tank body 11 is inspected.

[0037] Control plates 19 are provided on both sides of the support frame 2. A second scanning probe 20 is fixedly provided on the opposite side of the two control plates 19. Insert rods 21 are threaded on both ends of the two control plates 19. One end of each pair of insert rods 21 is threaded inside the support frame 2.

[0038] like Figure 2 and Figure 3 Insert the plug rod 21 into the interior of the two control plates 19 and the support frame 2, and use the second scanning probe 20 on one side of the two control plates 19 to detect the outer surface of the steel tank body 11.

[0039] The working principle of the non-destructive testing device for cracks in steel tanks provided by this utility model is as follows:

[0040] The steel tank body 11 is placed between the first limiting block 8 and the second limiting block 9. The positioning bolt 10 is threaded into the first limiting block 8 and the second limiting block 9 to fix the position of the steel tank body 11. By rotating the two rotating blocks 13, the two threaded rods 12 rotate at both ends of the support frame 2, causing the two sliding blocks 14 to slide on the inner side of the sliding groove 15, and causing the two magnetic blocks 16 to be attracted together. The two clamping blocks 17 are fixed at both ends of the steel tank body 11. The inner side of the steel tank body 11 is detected by the first scanning probe 18. The rotating rod 4 and the connecting block 5 are rotated by the output end of the motor 3, causing the connecting block 5 to slide on the upper surface of the moving rod 6, and causing the moving rod 6 to slide on the outer surface of the crossbar 7, thus rotating the steel tank body 11. The two control plates 19 are fixed on the upper surface of the workbench 1 by the insertion rod 21. The outer surface of the steel tank body 11 is detected by the second scanning probe 20.

[0041] Compared with related technologies, the non-destructive testing device for steel tank cracks provided by this utility model has the following beneficial effects:

[0042] Since the rotating component of this utility model includes a motor 3 and a rotating rod 4, and the detection component includes a first scanning probe 18 and a control board 19, the rotating rod 4, the connecting block 5 and the moving rod 6 work together to drive the crossbar 7 and the steel tank body 11 to rotate. The first scanning probe 18 and the second scanning probe 20 are used to detect the inside and outside of the steel tank body 11, thereby improving the detection efficiency of the steel tank body 11.

[0043] Since the positioning assembly includes threaded rods 12 and rotating blocks 13, by rotating the rotating blocks 13, the two threaded rods 12 rotate at both ends of the support frame 2. They are attracted together by the two magnetic blocks 16, and the two rotating blocks 13 are fixed at both ends of the support frame 2. The two clamping blocks 17 are fixed at both ends of the steel tank body 11, which facilitates the limiting of the steel tank body 11.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
