Description
Technical Field
[0001] This utility model relates to the field of pipeline non-destructive testing technology, specifically an auxiliary support structure for pipeline non-destructive testing. Background Technology
[0002] In pipeline production and installation, non-destructive testing (NDT) is a crucial process for ensuring quality and safety. Traditional ground-based inspection methods have significant drawbacks. When inspecting the lower end of a pipeline, the heavy pipe must be rolled over, an operation that often requires multiple people working together, consuming considerable manpower and time, severely impacting inspection efficiency. Therefore, auxiliary support structures are needed to provide stable support for the pipeline, facilitating inspection.
[0003] A prior art patent, CN220179087U, discloses an auxiliary support device for pipeline inspection, comprising a bracket and a second rocker arm. The base is placed beside the pipeline to be inspected. By cranking the first screw, a support block is moved below the pipeline. The second rocker arm is then cranked to support the pipeline. The height of the support can be adjusted according to actual needs. The position of the pipeline can also be adjusted using the first rocker arm to facilitate inspection. After inspection, the second rocker arm is cranked to lower the pipeline, and then the first rocker arm is cranked again to retract the bracket before supporting the next pipeline.
[0004] When the above-mentioned device performs support inspection on pipelines, the pipelines are large, and after inspecting one side, the pipelines need to be flipped over for inspection, which is quite troublesome and has low inspection efficiency. In order to address the above problems, an auxiliary support structure for non-destructive testing of pipelines is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an auxiliary support structure for non-destructive testing of pipelines to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An auxiliary support structure for non-destructive testing of pipelines includes a fixed ring and a fixed seat fixedly connected to the bottom of the fixed ring. Two sets of limiting wheels are rotatably connected inside the fixed ring, and an adjustment component for supporting the limiting wheels is provided on the fixed ring.
[0008] The adjustment assembly includes a mounting base and a through hole. Two sets of mounting bases are fixedly connected to both sides of the fixed ring, and two sets of through holes are respectively opened on both sides of the inner wall of the fixed ring. An operating groove is opened on one side of the mounting base, and the operating groove communicates with the through hole. A rotating frame is rotatably connected in the operating groove, and the limiting wheel is installed at one end of the rotating frame.
[0009] The bottom of the inner wall of the fixed ring is equipped with a support wheel, the top of the fixed seat is provided with a rotating groove, the rotating groove is provided with a sliding component for adjusting the rotation of the rotating frame, and the fixed ring is equipped with a limiting component for positioning the pipeline.
[0010] In one alternative: the sliding assembly includes a linkage rod and a slider. The linkage rod is rotatably connected to the end of the rotating frame away from the limiting wheel. The top of the slider is rotatably connected to the end of the linkage rod away from the rotating frame. The bottom of the inner wall of the rotating groove is provided with a groove for sliding with the two sets of sliders. A moving part is provided on one side of the fixed seat for driving the two sets of sliders to move closer together.
[0011] In one alternative embodiment: the limiting assembly includes a limiting block and an adjusting bolt. The limiting block is disposed inside a fixed ring, the adjusting bolt is threaded to the top of the fixed ring, the bottom of the adjusting bolt is rotatably connected to the limiting block, two sets of guide rods are fixedly connected to the top of the limiting block, and the top of the fixed ring is provided with sliding holes for sliding up and down in cooperation with the guide rods.
[0012] In one alternative: the moving part includes a bidirectional threaded rod, which is rotatably connected in a slide groove. A turntable is installed at one end of the bidirectional threaded rod extending to the outside. The bidirectional threaded rod is threadedly connected to two sets of sliders, and the two sets of threads on the bidirectional threaded rod corresponding to the sliders have opposite directions of rotation.
[0013] In one alternative: the bottom of the limiting block is provided with an anti-slip rubber pad.
[0014] In one alternative: both the groove and the slider have T-shaped cross-sections.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention incorporates limiting wheels, support wheels, an adjusting component, and a sliding component. The sliding component drives the rotating frame to rotate, which rotates within the through hole and operating groove. This causes the limiting wheels to rotate and approach the pipe, clamping and fixing it in place. Two sets of limiting wheels, in conjunction with a set of support wheels, clamp the pipe. Rotating the pipe causes the two sets of limiting wheels and support wheels to rotate as well. This facilitates inspection by staff, reduces the time spent on handling and constantly adjusting the observation angle, and improves inspection efficiency.
[0017] This utility model uses a limiting component. When the adjusting bolt is rotated, the limiting block slides downward. The limiting block drives two sets of guide rods to slide downward on the fixed ring, so that the limiting block positions the pipeline, reduces shaking, and facilitates detailed observation and inspection by the staff.

[0023] 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.
[0024] Please see Figures 1-3 In this embodiment, a pipeline non-destructive testing auxiliary support structure includes a fixed ring 11 and a fixed seat 12 fixedly connected to the bottom of the fixed ring 11. Two sets of limiting wheels 17 are rotatably connected inside the fixed ring 11, and an adjustment component for supporting the limiting wheels 17 is provided on the fixed ring 11.
[0025] The adjustment assembly includes a mounting base 15 and a through hole 13. Two sets of mounting bases 15 are fixedly connected to both sides of the fixing ring 11. Two sets of through holes 13 are respectively opened on both sides of the inner wall of the fixing ring 11. An operating groove 14 is opened on one side of the mounting base 15. The operating groove 14 is connected to the through hole 13. A rotating frame 16 is rotatably connected in the operating groove 14. A limiting wheel 17 is installed at one end of the rotating frame 16. The sliding assembly drives the rotating frame 16 to rotate in the operating groove 14 and the through hole 13, thereby driving the limiting wheel 17 to approach the pipe and clamp and fix the pipe, which is convenient for staff to perform inspection, reduces the time for handling and constantly adjusting the observation angle, and improves the inspection efficiency.
[0026] A support wheel 18 is installed at the bottom of the inner wall of the fixed ring 11, and a rotating groove 19 is provided at the top of the fixed seat 12. A sliding component for adjusting the rotation of the rotating frame 16 is provided in the rotating groove 19, and a limiting component for positioning the pipeline is installed on the fixed ring 11.
[0027] The sliding assembly includes a connecting rod 20 and a slider 22. The connecting rod 20 is rotatably connected to the end of the rotating frame 16 away from the limiting wheel 17. The top of the slider 22 is rotatably connected to the end of the connecting rod 20 away from the rotating frame 16. The bottom of the inner wall of the rotating groove 19 is provided with a sliding groove 21 for sliding with the two sets of sliders 22. A moving part is provided on one side of the fixed seat 12 for driving the two sets of sliders 22 to move closer together. The moving part drives the connecting rod 20 to move, pushing the rotating frame 16 to rotate. As the rotating frame 16 rotates, the connecting rod 20 rotates. The rotation of the rotating frame 16 brings the limiting wheel 17 closer to the pipe, thereby clamping and fixing the pipe.
[0028] The limiting assembly includes a limiting block 24 and an adjusting bolt 26. The limiting block 24 is disposed inside the fixing ring 11. The adjusting bolt 26 is threadedly connected to the top of the fixing ring 11, and the bottom of the adjusting bolt 26 is rotatably connected to the limiting block 24. Two sets of guide rods 25 are fixedly connected to the top of the limiting block 24. The top of the fixing ring 11 has a sliding hole for sliding up and down with the guide rods 25. When the adjusting bolt 26 is rotated, the limiting block 24 slides downward, and the limiting block 24 drives the two sets of guide rods 25 to slide downward on the fixing ring 11, so that the limiting block 24 positions the pipeline, reduces shaking, and facilitates detailed observation and inspection by the staff.
[0029] The moving component includes a bidirectional threaded rod 23, which is rotatably connected to a slide groove 21. A turntable is installed at one end of the bidirectional threaded rod 23 extending to the outside. The bidirectional threaded rod 23 is threadedly connected to two sets of sliders 22. The two sets of threads on the bidirectional threaded rod 23, corresponding to the sliders 22, have opposite directions of rotation. Rotating the turntable causes the bidirectional threaded rod 23 to rotate. As the bidirectional threaded rod 23 rotates, the two sets of sliders 22 slide towards each other in the slide groove 21. As the sliders 22 slide, the connecting rod 20 can be moved, thereby driving the rotating frame 16 to rotate.
[0030] The bottom of the limiting block 24 is provided with an anti-slip rubber pad, which can reduce the shaking of the pipeline and facilitate the inspection by the staff.
[0031] Both the slide groove 21 and the slider 22 have T-shaped cross sections. By setting the slide groove 21 and the slider 22 with T-shaped cross sections, the linkage rod 20 can move more smoothly.
[0032] The working principle of this utility model is as follows: In use, two sets of fixing seats 12 are placed according to the required pipe length. The pipe is passed through two sets of fixing rings 11, and the bottom of the pipe contacts two sets of support wheels 18. Rotating the turntable drives the bidirectional threaded rod 23 to rotate. As the bidirectional threaded rod 23 rotates, the two sets of sliders 22 slide towards each other in the slide groove 21. As the sliders 22 slide, the connecting rod 20 moves, pushing the rotating frame 16 to rotate. As the rotating frame 16 rotates, the connecting rod 20 rotates on the sliders 22. The rotation of the rotating frame 16 brings the limiting wheel 17 closer to the pipe, thereby clamping and fixing the pipe. Two sets of limiting wheels 17 and one set of support wheels 18 work together to clamp and fix the pipeline. When performing non-destructive testing on the pipeline, rotating the pipeline causes the two sets of limiting wheels 17 and support wheels 18 to rotate, facilitating the inspection by the staff, reducing the time spent on handling and constantly adjusting the observation angle, and improving the inspection efficiency. When the pipeline is fixed for observation, rotating the adjusting bolt 26 causes the limiting block 24 to slide downward. The limiting block 24 drives the two sets of guide rods 25 to slide downward on the fixing ring 11, positioning the pipeline and reducing shaking, making it easier for the staff to conduct detailed observation and inspection.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
