Description

Technical Field

[0001] This utility model relates to the field of pipeline flaw detection technology, specifically to an auxiliary device for multi-angle flaw detection of weld seams in high-pressure oil pipelines. Background Technology

[0002] High-pressure oil pipelines are a component of high-pressure oil circuits. They are required to withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. Since the pipeline usually carries high pressure, after the pipeline is welded together, it is necessary to inspect whether the weld is qualified. Once the weld has defects, it is very likely to cause serious accidents such as leakage or even pipeline rupture. Therefore, it is necessary to use flaw detection auxiliary devices to detect flaws in the pipeline.

[0003] Currently, the usual method for inspecting and detecting flaws in pipelines is for workers to hold a probe head and perform a circumferential inspection along the direction of the weld seam. This requires repeatedly taking images of the flaws along the weld seam of the pipeline. This method is not only inconvenient, but also becomes more difficult to use for some pipelines with larger diameters, thus reducing the efficiency of the inspection. To address this, we propose a multi-angle flaw detection auxiliary device for high-pressure oil pipeline weld seams. Utility Model Content

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1-4 In this embodiment of the present invention, a multi-angle flaw detection auxiliary device for high-pressure oil pipeline welds includes: a first support frame 1 and a second support frame 2. The inner surfaces of the first support frame 1 and the second support frame 2 are provided with fixing mechanisms 3. A gear sleeve 4 is connected to one of the fixing mechanisms 3. A driving mechanism 5 is provided on one side of the first support frame 1, and the driving mechanism 5 meshes with the gear sleeve 4. An adjustment mechanism 6 is provided between the tops of the first support frame 1 and the second support frame 2.

[0025] Specifically, the pipeline is passed through the first support frame 1 and the second support frame 2 and placed on two fixed mechanisms 3. Rotating the two fixed mechanisms 3 completes the fixation of the pipeline. Finally, the drive mechanism 5 is activated to drive the gear sleeve 4 to rotate one of the fixed mechanisms 3. One of the fixed mechanisms 3 drives the other fixed mechanism 3 to rotate together through the pipeline, so that the pipeline can rotate 360 ​​degrees. Finally, the adjustment mechanism 6 can be used to perform multi-angle flaw detection on the pipeline. By activating the adjustment mechanism 6, the pipeline can be moved laterally on the outer surface of the pipeline, which facilitates flaw detection of welds at other locations of the pipeline.

[0026] Example 2:

[0027] Please see Figure 3 In this embodiment of the present invention, a multi-angle flaw detection auxiliary device for high-pressure oil pipeline welds includes a fixing mechanism 3 comprising a rotating ring 301, four bolts 302, four handles 303, and four positioning rubber posts 304. The rotating ring 301 is rotatably connected to the inner surface of the first support frame 1, and both sides of the rotating ring 301 extend to the outside of the first support frame 1. The four bolts 302 are threaded at equal intervals to the outer surface of the rotating ring 301, and one end of each of the four bolts 302 extends to the inner surface of the rotating ring 301. The four handles 303 are respectively connected to... At the other end of the four bolts 302, four positioning rubber posts 304 are respectively connected to one end of the four bolts 302. The outer surface of the rotating ring 301 is connected to the gear sleeve 4, and the gear sleeve 4 is located on one side of the first support frame 1. The drive mechanism 5 includes a mounting frame 501, a first motor 502 and a pinion 503. The mounting frame 501 is connected to one side of the first support frame 1, the first motor 502 is connected to the top of the mounting frame 501, and the pinion 503 is connected to one end of the output shaft of the first motor 502, and the pinion 503 meshes with the gear sleeve 4.

[0028] Specifically, the pipeline is placed inside the rotating ring 301. Rotating the four handles 303 causes the four bolts 302 to move threadedly on the outer surface of the rotating ring 301, thereby causing the four positioning rubber posts 304 to fit against the outer surface of the pipeline and compress it. The output shaft of the first motor 502 is started to drive the pinion 503 to rotate. The pinion 503 will drive the gear sleeve 4 to drive the rotating ring 301 to rotate inside the first support frame 1, so that the fixed pipeline can rotate. Then, the flaw detection component 606 is used to perform flaw detection on the rotating pipeline, thus completing the multi-angle flaw detection of the pipeline.

[0029] Example 3:

[0030] Please see Figures 1-4 In this embodiment of the present invention, a multi-angle flaw detection auxiliary device for high-pressure oil pipeline welds includes an adjustment mechanism 6 comprising a hollow frame 601, a threaded rod 602, a second motor 603, and a threaded block 604. The hollow frame 601 is connected between the tops of the first support frame 1 and the second support frame 2. The threaded rod 602 is rotatably connected between the two sides of the inner wall of the hollow frame 601. The second motor 603 is connected to one side of the hollow frame 601, and one end of the output shaft of the second motor 603 extends into the interior of the hollow frame 601 and is connected to one end of the threaded rod 602. The threaded block 604 is threadedly connected to the outer surface of the second motor 603. The adjustment mechanism 6 also includes an electric push rod 605 and a flaw detection component 606. The electric push rod 605 is connected to the bottom of the threaded block 604, and the flaw detection component 606 is connected to the bottom of the electric push rod 605. The bottoms of the first support frame 1 and the second support frame 2 are both connected to a base 7.

[0031] Specifically, starting the output shaft of the second motor 603 drives the threaded rod 602 to rotate, causing the threaded block 604 to move threadedly on the outer surface of the threaded rod 602. The electric push rod 605 drives the flaw detection component 606 to move left and right, thereby adjusting the position of the flaw detection component 606 to facilitate flaw detection of welds at different locations on the pipeline. Finally, the height of the flaw detection component 606 can be adjusted by the electric push rod 605 to adapt to flaw detection of pipelines of different specifications. The setting of two bases 7 can improve the stability of the first support frame 1 and the second support frame 2 placed on the ground.

[0032] The working principle of this utility model is as follows: First, the pipeline to be inspected is placed inside the rotating ring 301. Then, the four handles 303 are rotated, which drives the four bolts 302 to rotate and move on the outer surface of the rotating ring 301. This causes the four positioning rubber posts 304 to approach the outer surface of the pipeline and compress it. With the help of another second support frame 2, the pipeline can be fixed. At this time, the operator starts the first motor 502. The output shaft of the first motor 502 drives the pinion 503 to rotate. When the pinion 503 rotates, it drives the gear sleeve 4 to rotate the rotating ring 301 inside the first support frame 1, thereby driving the fixed pipeline to enter the rotating ring 301. The rotation allows the flaw detection component 606 to perform flaw detection on the rotating pipeline, thus completing multi-angle flaw detection of the pipeline. When the operator starts the second motor 603, the output shaft of the second motor 603 drives the threaded rod 602 to rotate inside the hollow frame 601, thereby causing the threaded block 604 to move threadedly on the outer surface of the threaded rod 602. The electric push rod 605 drives the flaw detection component 606 to move left and right, thereby adjusting the current position of the flaw detection component 606, so that flaw detection can be performed on welds at different locations on the pipeline. Finally, the height of the flaw detection component 606 can be adjusted by the electric push rod 605 to adapt to flaw detection of pipelines of different specifications.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
