[0002] Seamless steel pipe is made by piercing a whole round steel, and the steel pipe without weld on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into extrusion seamless steel pipes, pipe jacking, etc. According to the cross-sectional shape, seamless steel pipes are divided into two types: circular and special-shaped. Seamless steel pipes with an outer diameter greater than Φ180mm are called large-diameter seamless steel pipes. After the production of large-diameter seamless steel pipes, ultrasonic flaw detection equipment is usually used to detect the quality of large-diameter seamless steel pipes, so as to improve the production quality of large-diameter seamless steel pipes.
[0003] At present, when large-diameter seamless steel pipes are inspected for quality, they are directly inserted into the ultrasonic flaw detection equipment. Although this is simple and convenient, when the ultrasonic flaw detection equipment detects large-diameter seamless steel pipes, the detection angle and detection surface are only the detection points of the large-diameter seamless steel pipe facing the ultrasonic flaw detection equipment. The single-angle detection and single-surface detection of large-diameter seamless steel pipes make the detection results of large-diameter seamless steel pipes inaccurate.
[0004] Therefore, those skilled in the art have provided an ultrasonic flaw detection device for large-diameter seamless steel pipe quality inspection to solve the problems raised in the above background technique. Content of the Utility Model

Specific implementation manner
[0021] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an ultrasonic flaw detection device for quality inspection of large-diameter seamless steel pipes includes a support frame 1, and a plurality of groups of installation bases 2 are fixedly arranged on the support frame 1. Each group of the installation bases 2 is two, and a transmission wheel 3 is rotatably arranged between the two installation bases 2. A seamless steel pipe turnover conveying assembly is arranged on the support frame 1, and an ultrasonic flaw detection assembly is arranged above the support frame 1.
[0022] The seamless steel pipe turnover conveying assembly includes a fixing plate 4 fixedly arranged on the support frame 1. U-shaped frames 5 are arranged on both sides of the upper end surface of the fixing plate 4. One end of the U-shaped frame 5 is rotatably provided with a connecting block 6. A connecting groove is formed in the connecting block 6, and a runner 7 is rotatably arranged in the connecting groove. The positions of the two runners 7 correspond to each other. A first transmission gear 8 and a second transmission gear 9 are rotatably arranged on the connecting block 6. The first transmission gear 8 and the second transmission gear 9 are meshed with each other. The first transmission gear 8 is butted against the runner 7 in the connecting groove. An installation frame 90 is arranged above the second transmission gear 9. The installation frame 90 is fixedly connected with the connecting block 6. A first servo motor 10 is fixedly arranged on the installation frame 90. The output end of the first servo motor 10 is butted against the second transmission gear 9. A second servo motor 11 is fixedly arranged on the U-shaped frame 5. The output end of the second servo motor 11 is butted against the connecting block 6. A moving assembly is arranged on the fixing plate 4, and the moving assembly is used for horizontally moving the U-shaped frame 5 on the fixing plate 4.
[0023] In this example: First, start the second servo motor 11. The start of the second servo motor 11 drives the connecting block 6 to rotate. The rotation of the connecting block 6 drives the runner 7 to rotate. When the runner 7 rotates to an appropriate angle, turn off the second servo motor 11 and start the first servo motor 10. The start of the first servo motor 10 drives the second transmission gear 9 connected to it to rotate. The rotation of the second transmission gear 9 drives the first transmission gear 8 to rotate. The rotation of the first transmission gear 8 drives the runner 7 to rotate. Then, place the seamless steel pipe to be detected on the driving wheel 3 on the support frame 1. When the seamless steel pipe to be detected is pushed to the ultrasonic flaw detection component, the ultrasonic flaw detection component detects the seamless steel pipe. The seamless steel pipe passing through the ultrasonic flaw detection component will be conveyed to the two runners 7. The runner 7 with an angle and rotating will convey the seamless steel pipe. The seamless steel pipe will be flipped during the conveying process. At this time, the ultrasonic flaw detection component will perform detection under the flip. The seamless steel pipe passing through the two runners 7 will be conveyed to the ultrasonic flaw detection component again, and the ultrasonic flaw detection component will perform re-detection on the rotating seamless steel pipe. When the tail end of the seamless steel pipe passes through the two runners 7, grasp the head section of the seamless steel pipe and extract it from the driving wheel 3.
[0024] Through the setting of the seamless steel pipe flipping and conveying component, not only can the seamless steel pipe be flipped during detection, so that the ultrasonic flaw detection component can perform ultrasonic detection on multiple surfaces of the seamless steel pipe, thereby improving the accuracy of seamless steel pipe detection, but also it can play a role in conveying the seamless steel pipe, thus reducing the labor of the staff continuously pushing the seamless steel pipe manually during the detection of the seamless steel pipe; in addition, the adjustable angle of the runner 7 enables the rotation speed of the seamless steel pipe during detection and the conveying speed of the seamless steel pipe to be regulated.
[0025] The moving component includes two sliding grooves 12 opened on the fixed plate 4 and a driver 13 fixedly arranged on the fixed plate 4. The positions of the two sliding grooves 12 correspond to those of the two U-shaped frames 5. A slider 14 is slidably arranged in the sliding groove 12. The two sliders 14 are respectively fixedly connected to the two U-shaped frames 5. The output end of the driver 13 is provided with a threaded rod 15. One end of the threaded rod 15 sequentially passes through the sliders 14 in the two sliding grooves 12 and is rotatably connected to the fixed plate 4.
[0026] In this example: If replacing seamless steel pipes of different calibers, start the driver 13 according to the caliber of the seamless steel pipe. The start of the driver 13 drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 drives the two U-shaped frames 5 to move in opposite or opposite directions through the slider 14 until the distance between the two runners 7 is adapted to the caliber of the seamless steel pipe to be detected. Through the setting of the moving component, the seamless steel pipe flipping and conveying component can be applicable to seamless steel pipes of different calibers.
[0027] The ultrasonic flaw detection assembly includes a fixing frame 16, on which a cylinder 17 is fixedly arranged. The output end of the cylinder 17 passes through the fixing frame 16, and a connecting plate 18 is fixedly arranged at the output end of the cylinder 17. An ultrasonic detector 19 is fixedly arranged on the connecting plate 18. A guide rod 20 is arranged on the connecting plate 18. There are four guide rods 20, and the four guide rods 20 are arranged in a rectangular pattern. One end of each guide rod 20 passes through the connecting plate 18, and a limit block 21 is fixedly arranged at the end of the guide rod 20 passing through the connecting plate 18. When it is necessary to adjust the vertical height of the ultrasonic detector 19, start the cylinder 17. The start of the cylinder 17 drives the connecting plate 18 to move up and down along the guide rod 20. The movement of the connecting plate 18 drives the ultrasonic detector 19 to move. When the ultrasonic detector 19 moves to an appropriate height, turn off the cylinder 17. The arrangement of the cylinder 17 drives the ultrasonic detector 19 to adjust the height, and the arrangement of the guide rod 20 is used to guide the connecting plate 18 to move up and down.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
