Abstract

[0002] The quality defects of steel pipes are mainly caused by a combination of factors such as raw materials, production processes, equipment status and human operation. At the raw material stage, non-metallic inclusions or component segregation in the steel billet will be directly inherited to the interior of the steel pipe, causing problems such as cracks, delamination or insufficient corrosion resistance. In the production process, improper hot rolling process parameters can easily cause internal bending, external warping or uneven wall thickness; if the mold is worn or poorly lubricated during cold processing, it will cause surface scratches or residual stress concentration. When welding steel pipes, defects are caused by insufficient welding current, impure shielding gas or incomplete interlayer cleaning. Uneven heat treatment and corrosion in the storage environment will also aggravate the formation of defects.

[0020] [Example 1] In the prior art, inadequate inspection of steel pipes results in defective steel pipes being used directly in the industry, increasing safety risks. The present invention provides the following solutions: like Figure 1-2 As shown, an embodiment of the present invention provides a steel pipe inspection device, comprising a device frame 1 and a steel pipe fixing frame 2. A first steel pipe visual mechanism 3 is provided within the device frame 1, and a steel pipe fixing frame 2 is provided with a steel pipe clamping mechanism 4. The first steel pipe visual mechanism 3 includes a height adjustment mechanism 31, a first lateral movement mechanism 32, and a second lateral movement mechanism 33. The height adjustment mechanism 31 is mounted on the device frame 1, and the first lateral movement mechanism 32 and the second lateral movement mechanism 33 are respectively mounted on the height adjustment mechanism 31. The first lateral movement mechanism 32 and the second lateral movement mechanism 33 are symmetrically arranged, and each of the first lateral movement mechanism 32 and the second lateral movement mechanism 33 is equipped with a visual camera group 34.
[0021] It should be noted that the steel pipe 7 to be inspected is moved to the device frame 1 and the steel pipe fixing frame 2, and the steel pipe 7 to be inspected is fixed and clamped by the steel pipe clamping mechanism 4. The height adjustment mechanism 31 adjusts the height of the first lateral moving mechanism 32 and the second lateral moving mechanism 33 according to the diameter of the steel pipe 7 to be inspected, that is, the height of the visual camera group 34 is adjusted. The first lateral moving mechanism 32 and the second lateral moving mechanism 33 adjust the lateral position of the visual camera group 34 according to the diameter of the steel pipe 7 to be inspected. After the adjustment is completed, the visual camera groups 34 on the left and right sides are aligned with the steel pipe 7 to be inspected for detection and identification. The steel pipe defect detection model obtained by training with the deep learning framework identifies the types of steel pipe defects, such as weld cracks, weld tears, sand holes, notches, scratches, severe bumps, etc.
[0022] In some embodiments, the height adjustment mechanism 31 includes a lifting frame 311, an adjustment frame 312, and a fixing plate 313. The fixing plate 313 is mounted on the device frame 1. One end of the adjustment frame 312 is connected to the lifting frame 311, and the other end of the adjustment frame 312 is movably connected to the fixing plate 313.
[0023] It should be noted that, by adjusting the height of the adjustment frame 312 on the fixing plate 313 , the lifting frame 311 is adjusted to an appropriate position according to the diameter of the steel pipe 7 to be inspected.
[0024] In some embodiments, the adjustment frame 312 and the fixing plate 313 are both provided with a plurality of height adjustment slots corresponding to each other.
[0025] It should be noted that the adjustment slots of the adjustment frame 312 and the fixing plate 313 correspond to each other and are adjusted to appropriate positions and fixed by bolts and nuts.
[0026] In some embodiments, the first lateral movement mechanism 32 and the second lateral movement mechanism 33 each include a lateral movement frame 351, a guide shaft 352, a screw 353, and a hand rotation member 354. The visual camera assembly 34 is mounted on the lateral movement frame 351. The guide shaft 352 passes through the lateral movement frame 351 and is connected to both sides of the lifting frame 311. Screw rod seats 355 are provided on both sides of the lateral movement frame 351. The screw rod 353 is mated with the screw rod seats 355 and passes through the lifting frame 311 to connect to the hand rotation member 354.
[0027] It should be noted that by rotating the hand rotating part 354, the screw seat 355 moves on the screw 353, and the guide shaft 352 plays a guiding and stabilizing role, so that the horizontal moving frame 351 can be moved to the appropriate position, so that the visual camera group 34 can be moved to the appropriate position.
[0028] In some embodiments, the vision camera group 34 includes a plurality of side vision cameras 341 tilted at 45 degrees.
[0029] It should be noted that the visual camera group 34 is provided with four lateral visual cameras 341, which are divided into two lateral visual cameras 341 in the upper row and two lateral visual cameras 341 in the lower row. The lateral visual cameras 341 in the upper row are tilted 45 degrees downward, and the lateral visual cameras 341 in the lower row are tilted 45 degrees upward.
[0030] In some embodiments, a steel pipe stabilizing block 3511 is provided on one side of the transverse moving frame 351 , and the steel pipe stabilizing block 3511 is provided with an arc groove.
[0031] It can be understood that the steel pipe stabilizing block 3511 can be placed in the arc groove of the steel pipe stabilizing block 3511, which plays a stabilizing role for the steel pipe 7 to be tested.
[0032] In some embodiments, the device also includes a second steel tube visual mechanism 5 located on one side of the first steel tube visual mechanism 3. The second steel tube visual mechanism 5 is equipped with a vertical visual camera 51 with a lens facing vertically downward. A bowl-shaped body 511 with a hollow center is provided below the vertical visual camera 51.
[0033] It should be noted that the vertical visual camera 51 cooperates with the bowl-shaped body 511 to detect and identify the top of the steel pipe 7 to be inspected.
[0034] In some embodiments, the steel pipe clamping mechanism 4 includes a plurality of telescopic devices 41 evenly distributed in a circumferential array.
[0035] It should be noted that the telescopic device 41 can be a cylinder or an electric telescopic rod. Preferably, three telescopic devices 41 are evenly distributed in a circular array. When the telescopic ends are extended together, they can clamp and fix the steel pipe 7 to be tested.
[0036] In some embodiments, circular air knives 6 are provided at both the front and rear ends of the device frame 1 for blowing away water stains and dirt on the surface of the steel pipe, thereby effectively reducing detection errors.
[0037] [Example 2] The embodiment of the present invention further provides a detection method using the steel pipe detection device in Example 1, comprising: Step 1: Place the steel pipe to be inspected into the inspection position and clamp it securely using the steel pipe clamping mechanism.
[0038] It should be noted that the steel pipe 7 to be inspected is moved to the device frame 1 and the steel pipe fixing frame 2, and is fixed and clamped by the steel pipe clamping mechanism 4. The telescopic device 41 can be a cylinder or an electric telescopic rod. Preferably, three telescopic devices 41 are evenly distributed in a circular array. When the telescopic ends are extended together, the steel pipe 7 to be inspected is clamped and fixed.
[0039] Step 2: Detect defects of the steel pipe through the first steel pipe visual mechanism and the second steel pipe visual mechanism.
[0040] It should be noted that the height adjustment mechanism 31 adjusts the height of the first and second transverse movement mechanisms 32, 33, based on the diameter of the steel pipe 7 to be inspected, thereby adjusting the height of the visual camera group 34. The first and second transverse movement mechanisms 32, 33 adjust the transverse position of the visual camera group 34 based on the diameter of the steel pipe 7 to be inspected. After adjustment, the left and right visual camera groups 34 are aligned with the steel pipe 7 to be inspected for inspection and identification. This is then coordinated with the second steel pipe visual mechanism 5 for inspection and identification. The steel pipe defect detection model trained using a deep learning framework identifies steel pipe defects, such as weld cracks, weld tears, pinholes, notches, scratches, and severe bruises.
[0041] Step three: The steel pipe defect detection model trained through the deep learning framework is used to identify the defect types of the steel pipe.
[0042] It should be noted that the deep learning framework uses YOLOv10. By marking the defect features of the steel pipe surface image, a defect target detection model is trained. This can perform real-time detection of the steel pipe surface quality, identify various types of defects detected, and identify the specific information of the defects.
[0043] In summary, embodiments 1-2 of the present invention provide a steel pipe inspection device and method, which perform all-round inspection of steel pipes by setting a steel pipe clamping mechanism and a steel pipe visual mechanism. The steel pipe defect detection model obtained by training with a deep learning framework can effectively identify defects in steel pipes and avoid safety hazards in subsequent applications.
