Description

Technical Field

[0001] This utility model relates to the field of steel pipe flaw detection technology, and specifically to an auxiliary device for steel pipe flaw detection. Background Technology

[0002] Steel pipes are the most widely used type of steel. Their quality directly affects economic benefits and the safety of people's lives. Countries around the world attach great importance to the quality inspection of steel pipes and have adopted various non-destructive testing methods to conduct strict inspections of steel pipes. Flaw detection usually detects cracks or defects inside metal materials or components.

[0003] However, in the traditional method of flaw detection of steel pipes, workers usually manually rotate the steel pipes and then use fixed flaw detection equipment to complete the inspection. This process not only increases the working time of the workers, but is also time-consuming and labor-intensive, and reduces the speed and efficiency of flaw detection of steel pipes. In addition, the surface of steel pipes that have been stored for a long time usually has dust or impurities attached to it, which cannot be cleaned before flaw detection, thus greatly reducing the reliability of the flaw detection results after the flaw detection process. Utility Model Content

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a steel pipe flaw detection auxiliary device, which includes a base 1, a rolling assembly 2 on the base 1, and a movable flaw detection assembly 3 on the base 1 above the rolling assembly 2.

[0023] The rolling assembly 2 includes two support seats 21 fixedly connected to the base 1. A rotating shaft 22 is rotatably connected to the two support seats 21. A rotating roller 23 is provided on the rotating shaft 22 between the two support seats 21. Several anti-slip blocks 24 are provided on the rotating roller 23. By providing several anti-slip blocks 24 on the rotating roller 23, the steel pipe can be effectively rotated.

[0024] Two support bases 21 are fixedly connected to one side of an arc-shaped fixing block 25. The two arc-shaped fixing blocks 25 are rotatably connected to a rotating shaft 26. The rotating shaft 26 is provided with a contact post 27. The top of the two arc-shaped fixing blocks 25 is fixedly connected to a stand 28. Limiting wheels 29 are rotatably installed in the two stands 28. The limiting wheels 29 are provided with several anti-slip blocks 210. The two limiting wheels 29 are used in conjunction with the anti-slip blocks 210 to prevent the steel pipe from detaching from the rotating roller 23 and the contact post 27 during rotation.

[0025] A drive motor 211 is fixedly connected to the base 1. The transmission end of the drive motor 211 is connected to the rotating shaft 22 through the transmission belt 212. The transmission end of the drive motor 211 can drive the rotating shaft 22 to rotate, thereby causing the rotating roller 23 to rotate.

[0026] The movable flaw detection component 3 includes an arc-shaped movable plate 31. One end of the arc-shaped movable plate 31 is hinged to one end of the drive motor 211 on the base 1. Two support seats 21 are hinged to one side of a telescopic cylinder 32. The output end of the telescopic cylinder 32 is hinged to the other end of the arc-shaped movable plate 31. During operation, the two hinged telescopic cylinders 32 can effectively raise or lower the arc-shaped movable plate 31, thereby facilitating the workers to pick up and put down the steel pipe.

[0027] An installation base 33 is provided on the arc-shaped movable plate 31 between the output ends of the two telescopic cylinders 32. The installation base 33 is equipped with the flaw detection device body 34. Several cleaning brushes 35 are provided on one side of the flaw detection device body 34 on the installation base 33. The cleaning brushes 35 can clean the steel pipe before the flaw detection device body 34 performs the inspection, thereby removing impurities or dust from the surface of the steel pipe, greatly improving the flaw detection efficiency and playing an auxiliary role.

[0028] The principle and usage process of this utility model:

[0029] When needed, the operator first activates the telescopic cylinders 32 hinged on both sides. The output end of the telescopic cylinder 32 extends the arc-shaped movable plate 31, raising it. At this time, the flaw detection device body 34 also rises, facilitating the subsequent steel pipe placement process. Then, the operator places the steel pipe to be inspected (the diameter of the steel pipe placed here will not exceed the inspection area of ​​the rotating roller 23 and the flaw detection device body 34) onto the rotating roller 23 and pushes it between the rotating roller 23 and the contact post 27. Then, the limiting wheels 29 on both sides are used to prevent the steel pipe from detaching from the rotating roller 23 and the contact post 27 during rotation. Finally, the telescopic cylinders 32 on both sides can be activated, allowing the... The output end retracts, and then the arc-shaped movable plate 31 can descend. The arc-shaped movable plate 31 can also block some dust. Then, the flaw detection device body 34 will also begin to lower. When the cleaning brushes 35 on the mounting base 33 are in contact with the surface of the steel pipe, the telescopic cylinders 32 on both sides are shut off, and the flaw detection device body 34 will not touch the surface of the steel pipe. Next, the drive motor 211 can be started. The transmission end of the drive motor 211 drives the rotating shaft 22 to rotate through the transmission belt 212. At this time, the steel pipe will also rotate. The cleaning brushes 35 on one side of the flaw detection device body 34 will first clean the rotating steel pipe, and then the flaw detection operation is completed by using the flaw detection device body 34.
