Description

Technical Field

[0001] This invention relates to a flaw detection device, specifically a testing device for carbon fiber pipes and its flaw detection data recording system, belonging to the technical field of flaw detection devices. Background Technology

[0002] Carbon fiber tubes, also known as carbon fiber tubes or carbon tubes, are made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin and then pultruding (winding) them through heating and curing. During the manufacturing process, various profiles can be produced using different molds, such as round carbon fiber tubes of different specifications, square tubes of different specifications, sheets of different specifications, and other profiles. 3K coating can also be used for surface finishing and aesthetic enhancement during the manufacturing process.

[0003] As pressure vessels, pipelines require flaw detection during inspection and construction to ensure that pipeline installation and processing meet quality requirements. Various flaw detection instruments are often used in the pipeline flaw detection process.

[0004] Currently, non-destructive radiographic inspection of pipeline welds generally employs the following equipment scheme: a wheeled trolley carries the X-ray tube, which is then moved to the weld. Electromechanical devices adjust the perpendicularity and focal length of the X-ray tube to the weld before X-ray imaging. Because the wheeled trolley operates at the bottom of the pipeline and relies on its own weight for balance, the contact friction with the pipe wall is relatively small, thus limiting its overall mobility. Therefore, after inspecting one pipeline, the flaw detection device typically needs to be manually removed and placed into another. With a large volume of product inspections, repeatedly moving the trolley and aligning it with the pipeline wastes a significant amount of time. Furthermore, the existing trolley cannot automatically transport materials across the gaps between pipelines, necessitating improvements. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a carbon fiber pipe inspection device and its flaw detection data recording system in order to solve the above-mentioned problems. This addresses the issue in the prior art where, under the workload of inspecting large quantities of products, manual repeated handling of trolleys and alignment of the trolleys with the pipes wastes a lot of time, and the existing trolleys cannot automatically transport materials through the gaps between pipes.

[0018] This invention provides a testing device for carbon fiber pipes and a flaw detection data recording system thereon, which has the following beneficial effects:

[0019] 1. The carbon fiber pipe inspection device and its flaw detection data recording system, by placing the device inside the pipe and activating the drive assembly, starts the first forward and reverse motors. The first forward and reverse motors drive the rotating plate to rotate. When the rotating plate rotates, multiple arc-shaped grooves inside limit and guide multiple probes. Because multiple guide rods simultaneously pass through multiple straight grooves and slide along the straight grooves, the guide rods slide along the straight grooves, thereby driving multiple adjusting rods to move inside multiple sliding sleeves. The multiple adjusting rods drive multiple mounting plates to move, and the multiple mounting plates drive rubber rollers to move, so that the multiple rubber rollers contact the inner wall of the pipe to support the device. At the same time, the branch pipe is supported in the middle of the pipe, so that multiple smooth sleeves and oblique sliding sleeves are located in the center of the pipe, allowing multiple probes to inspect the inner wall of the pipe. By starting multiple motors, the multiple motors drive multiple rubber rollers to rotate, allowing the device to move inside the pipe, facilitating flaw detection.

[0020] 2. The inspection device and flaw detection data recording system for the carbon fiber pipe: When the second reciprocating screw rotates, it moves to one side, driving the moving plate to move. The moving plate then drives the second connecting plate to move, which in turn drives the second hinge rod and the second support plate to move. The second support plate then drives the oblique sliding sleeve to move, causing the second hinge rod to contact the stop block at the front end of the branch pipe. This pushes the second hinge rod outward and causes the oblique sliding sleeve to open outward, supporting the inner wall of the pipe. Then, the first forward and reverse motor in the drive assembly connected to the electric push rod starts in the opposite direction, driving the rotating plate to reverse. This causes multiple rubber rollers to retract inward, and the electric push rod starts, driving the drive assembly connected to it to move, extending it into the second pipe. It then unfolds, supporting the second pipe. The oblique sliding sleeve then retracts inward, causing the rear drive device to start and move the rear end of the device forward. At the same time, the electric push rod is controlled to retract, moving the rear section of the device forward, which facilitates connection with subsequent pipes and facilitates subsequent inspection.

[0021] 3. The detection device and flaw detection data recording system for the carbon fiber pipe: When the first reciprocating screw reverses, it drives the second threaded sleeve to move, causing the second threaded sleeve to drive the moving ring to move, which in turn drives the sliding rod to move. The sliding rod pushes the push plate to move, causing the push plate to drive multiple first connecting plates to move. The first connecting plates then drive multiple first hinge rods and first support plates to move, causing the first support plates to drive the smooth sleeves to the intervals between multiple oblique sliding sleeves. The first hinge rods move to the side of the stop block, lifting the first hinge rods and driving the first support plates to lift. This causes the multiple first support plates to drive the multiple smooth sleeves to open outward, which then cooperates with the multiple oblique sliding sleeves. The front and rear drive components support the two pipes. When the smooth sleeves and oblique sliding sleeves open outward at the pipe gaps, the arc surfaces of the smooth sleeves and oblique sliding sleeves fit against the ends of the two pipes, thus supporting the ends of the pipes. This allows the probe to detect the ends of the pipes. During retraction, the smooth sleeves are first retracted, moving to disengage from the oblique sliding sleeves, and then the oblique sliding sleeves are retracted to prevent jamming and facilitate operation.

Detailed Implementation

[0038] This invention provides a testing device for carbon fiber pipes.

[0039] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The system includes a branch pipe 1, a connecting frame 2 fixedly connected to the outer side of one end of the branch pipe 1, a push plate 3 on one side of the connecting frame 2, a movable plate 4 inside the push plate 3, multiple first connecting plates 5 fixedly connected to the push plate 3 facing the branch pipe 1, and multiple second connecting plates 8 fixedly connected to the movable plate 4 facing the branch pipe 1. Each of the multiple first connecting plates 5 and the second connecting plates 8 has a U-shaped groove at one end. Both ends of the groove in the first connecting plate 5 are hinged to first hinge rods 6. Two first hinge rods 6 are hinged to a first support plate 7 away from the first connecting plate 5. A smooth sleeve 11 is fixedly connected to the outer side of the first support plate 7. Both ends of the groove in the second connecting plate 8 are hinged to second hinge rods 9. One end of each second hinge rod 9 is hinged to a second support plate 10. An oblique sliding sleeve 12 is fixedly connected to the outer side of the second support plate 10. Probes 39 are installed inside both the smooth sleeve 11 and the oblique sliding sleeve 12. A transmission assembly is provided at one end of the branch pipe 1, and drive assemblies are provided on the sides of the branch pipe 1 and the transmission assembly that are away from each other.

[0040] Multiple first connecting plates 5 and multiple second connecting plates 8 are arranged in a ring array on the outside of the branch pipe 1. Multiple first connecting plates 5 and multiple second connecting plates 8 are spaced apart. Multiple smooth sleeves 11 and multiple oblique sliding sleeves 12 are spaced apart and are assembled together to form a frustum shape. The two sides of multiple smooth sleeves 11 are flat, and the two sides of multiple oblique sliding sleeves 12 are set as inclined surfaces. Multiple stops are fixedly connected to the front end of the branch pipe 1 so that they will not get stuck when the smooth sleeves 11 and oblique sliding sleeves 12 are retracted.

[0041] The transmission assembly includes a support sleeve 13, a first reciprocating screw 14, and a second reciprocating screw 15. The first reciprocating screw 14 is rotatably connected inside the support sleeve 13, and the second reciprocating screw 15 is slidably connected inside the first reciprocating screw 14. Limiting rods 16 are fixedly connected to both sides of one end of the support sleeve 13. A limiting sleeve 17 is fixedly connected to the end of each limiting rod 16 away from the support sleeve 13. A first one-way bearing 18 is fixedly connected inside the limiting sleeve 17, and a first threaded sleeve 19 is installed inside the first one-way bearing 18. The second reciprocating screw 15 passes through the first threaded sleeve 19 and is threadedly connected to it. The second reciprocating screw 15 passes through a push plate 3 and is movably connected to it. One end of the second reciprocating screw 15 extends to the outside of the push plate 3 and is rotatably connected to a moving plate 4, so that the second reciprocating screw 15 drives the moving plate 4 to move when it moves. Slide plates 20 are fixedly connected to both sides of one end of the reciprocating screw 15. Slide grooves adapted to slide plates 20 are opened on both sides of the inside of the first reciprocating screw 14. The two slide plates 20 are slidably connected to the two slide grooves respectively, limiting the slide plates 20, so that the first reciprocating screw 14 drives the second reciprocating screw 15 to rotate. A second threaded sleeve 40 is threadedly connected to the outside of the first reciprocating screw 14. A second one-way bearing 21 is fixedly connected to the outside of the second threaded sleeve 40. A moving ring 22 is fixedly connected to the outside of the second one-way bearing 21. Two limiting rods 16 pass through the moving ring 22 and are slidably connected to the moving ring 22. Slide rods 24 are fixedly connected to both sides of one end of the moving ring 22. Two slide rods 24 pass through the limiting sleeve 17 and are slidably connected to the limiting sleeve 17. The front ends of the two slide rods 24 are fixedly connected to the push plate 3, so that the moving ring 22 moves and drives the push plate 3 to move.

[0042] The drive assembly includes a fixed plate 26, multiple sliding sleeves 27, and multiple adjusting rods 28. An electric push rod 25 is fixedly connected inside the branch pipe 1. One of the fixed plates 26 is fixedly connected to the output end of the electric push rod 25. A second forward and reverse motor 37 is fixedly connected to the rear side of the support sleeve 13. A connecting seat 38 is fixedly connected to the rear side of the second forward and reverse motor 37. Another fixed plate 26 is fixedly connected to the rear side of the connecting seat 38. Multiple sliding sleeves 27 are fixedly connected inside the fixed plate 26 in a circular array. Multiple adjusting rods 28 are slidably connected to the interior of multiple sliding sleeves 27. Multiple adjusting rods 28 all penetrate the side wall of the fixed plate 26 and are slidably connected to the fixed plate 26. One end of each of the multiple adjusting rods 28 is fixedly connected to a mounting plate 31. A motor 32 is fixedly connected inside each of the multiple mounting plates 31. Rubber rollers 33 are fixedly connected to both output ends of the motor 32. The motor 32 starts and drives the rubber rollers 33 to rotate, so that the rubber rollers 33 move on the inner wall of the pipe.

[0043] Multiple adjusting rods 28 are fixedly connected to one end of a guide rod 29. Multiple sliding sleeves 27 have straight grooves 30 inside one side wall. Multiple guide rods 29 pass through multiple straight grooves 30 and are slidably connected to multiple straight grooves 30. A rotating plate 35 is rotatably connected to one side of a fixed disk 26. Multiple arc-shaped grooves 36 are formed in a ring array inside the rotating plate 35. Multiple guide rods 29 pass through multiple arc-shaped grooves 36 and are slidably connected to multiple arc-shaped grooves 36. A first forward and reverse motor 34 is fixedly connected inside the fixed disk 26. The output end of the first forward and reverse motor 34 is fixedly connected to the rotating plate 35, so that the fixed disk 26 starts and drives the rotating plate 35 to rotate, thereby limiting the guide rods 29 by the multiple arc-shaped grooves 36.

[0044] By placing the device inside the pipeline and activating the drive assembly, the first forward and reverse motor 34 is started. The first forward and reverse motor 34 drives the rotating plate 35 to rotate. When the rotating plate 35 rotates, the multiple arc-shaped grooves 36 inside it limit and guide the multiple probes 39. Because the multiple guide rods 29 simultaneously pass through the multiple straight grooves 30 and slide along the straight grooves 30, the guide rods 29 slide along the straight grooves 30, thereby driving the multiple adjusting rods 28 to move inside the multiple sliding sleeves 27. The multiple adjusting rods 28 drive the multiple mounting plates 31 to move, and the multiple mounting plates 31 drive the rubber rollers 33 to move, so that the multiple rubber rollers 33 contact the inner wall of the pipeline to support the device. At the same time, the branch pipe 1 is supported in the middle of the pipeline, so that the multiple smooth sleeves 11 and the inclined sliding sleeves 12 are located in the center of the pipeline, allowing the multiple probes 39 to detect the inner wall of the pipeline. By starting the multiple motors 32, the multiple motors 32 drive the multiple rubber rollers 33 to rotate, so that the device can move inside the pipeline, which is convenient for flaw detection.

[0045] Example 2: When multiple sets of pipelines are inspected in batches, the pipelines can be placed on a conveyor belt for transportation, and the device can be inspected according to the scheme of Example 1. The device moves inside the pipeline while the pipeline moves on the conveyor belt. By keeping the speed of the device and the conveyor belt consistent, the device can remain stationary in its original position, which is beneficial for subsequent pipeline inspections.

[0046] Example 3: When performing batch testing on pipelines, after the device finishes testing the first pipeline and moves to the end of the pipeline, the conveyor belt stops, and the second forward and reverse motor 37 starts in the forward direction, driving the first reciprocating screw 14 to rotate forward. When the first reciprocating screw 14 rotates, it rotates through the slide plate 20, which in turn drives the second reciprocating screw 15 to rotate. When the second reciprocating screw 15 rotates forward, the first one-way bearing 18 limits the first threaded sleeve 19, thereby limiting the second reciprocating screw 15. When the second reciprocating screw 15 rotates, it moves to one side, driving the moving plate 4 to move. The moving plate 4 drives the second connecting plate 8 to move, and the second connecting plate 8 drives the second hinge rod 9 and the second support plate 10 to move, causing the second support plate 10 to drive the oblique sliding sleeve. 12 moves and makes the second hinge rod 9 contact the stop block at the front end of the branch pipe 1, thereby pushing the second hinge rod 9 to open outward and driving the inclined sliding sleeve 12 to open outward, supporting the inner wall of the pipe. Then, the first forward and reverse motor 34 in the drive assembly connected to the electric push rod 25 starts in reverse and drives the rotating plate 35 to reverse, causing multiple rubber rollers 33 to retract inward. The electric push rod 25 starts and drives the drive assembly connected to it to move, so that it extends into the second pipe and then unfolds to support the second pipe. Then, the inclined sliding sleeve 12 retracts inward, causing the rear drive device to start and drive the rear end of the device to move forward. At the same time, the electric push rod 25 is controlled to retract, so that the rear section of the device moves forward, which is conducive to connecting with the subsequent pipe and facilitates subsequent testing.

[0047] Example 4: When inspecting thicker pipes, when passing through the gaps between pipes, the second forward and reverse motor 37 is first started in the forward direction to repeat the steps of opening the oblique sliding sleeve 12 in Example 3. Then, the second forward and reverse motor 37 is controlled to start in the reverse direction, causing the second forward and reverse motor 37 to drive the first reciprocating screw 14 to rotate. When the first reciprocating screw 14 rotates in the reverse direction, it drives the second threaded sleeve 40 to move, causing the second threaded sleeve 40 to drive the moving ring 22 to move. The moving ring 22 then drives the sliding rod 24 to move, and the sliding rod 24 pushes the push plate 3 to move, causing the push plate 3 to drive multiple first connecting plates 5 to move. The first connecting plates 5 then drive multiple first hinge rods 6 and first support plates 7 to move, causing the first support plates 7 to drive the smooth sleeve 1. 1. Move to the interval between multiple oblique sliding sleeves 12, so that the first hinge rod 6 moves to the side of the stop block. The first hinge rod 6 is lifted and drives the first support plate 7 to be lifted, so that multiple first support plates 7 drive multiple smooth sleeves 11 to open outward, which can cooperate with multiple oblique sliding sleeves 12. The front and rear drive components support the two pipes. When the smooth sleeves 11 and oblique sliding sleeves 12 open outward at the pipe gap, the arc surface of the smooth sleeves 11 and oblique sliding sleeves 12 fits with the ends of the two pipes, thereby supporting the ends of the pipes. Then, the probe 39 detects the ends of the pipes. When retracting, the smooth sleeves 11 are first retracted, so that the smooth sleeves 11 move to disengage from the oblique sliding sleeves 12, and then the oblique sliding sleeves 12 are retracted to prevent jamming and facilitate operation.

[0048] Example 5: A testing device for carbon fiber pipes and its flaw detection data recording system. Please refer to [link / reference]. Figure 11 , Figure 12 , Figure 13 and Figure 14 The system includes a data acquisition module 100, an output terminal of which is connected to a central processing unit 200. The output terminal of the central processing unit 200 is connected to a data model transmission module 300. The output terminal of the data model transmission module 300 is connected to a feature scanning module 400. The output terminal of the feature scanning module 400 is connected to a data storage module 500. The data model transmission module 300 includes a model building unit 301, an output terminal of which is connected to a model export unit 302. The output terminal of the model export unit 302 is connected to a model combination analysis unit 303. The output terminal of the model combination analysis unit 303 is connected to a signal transmission unit 304. The feature scanning module 400 includes a feature extraction unit 401. The output of module 401 is connected to a feature matching unit 402. The output of feature matching unit 402 is connected to a feature compression unit 403. The output of feature compression unit 403 is connected to a gap recognition unit 404. The output of gap recognition unit 404 is connected to a data update unit 405. The output of data update unit 405 is connected to a signal transmission unit 406. The output of data storage module 500 is connected to a data scanning unit 501. The output of data scanning unit 501 is connected to a data encryption unit 502. The output of data encryption unit 502 is connected to a data compression unit 503. The output of data compression unit 503 is connected to a data storage unit 504. The output of data storage unit 504 is connected to a compressed upload unit 505.

[0049] Specifically, the data acquisition module 100 initiates the transmission of detection data to the central processing unit 200, which in turn sends a signal to the data model transmission module 300. The data model transmission module 300 then instructs the model building unit 301 to detect the data model and, in turn, instructs the model export unit 302 to export the model data. The model export unit 302 then instructs the model combination analysis unit 303 to analyze the model and, in turn, instructs the signal transmission unit 304 to transmit the analysis result signal. Next, the data model transmission module 300 sends a signal to the feature scanning module 400, which in turn instructs the feature extraction unit 401 to extract data features from the camera. Finally, the feature extraction unit 401 instructs the feature matching unit 402 to extract data features from the camera. 402 matches the detected features with the database and simultaneously sends a command to the feature compression unit 403 to identify the pipe gaps. Then, the gap identification unit 404 locates the feature coordinates, indicating that the previous pipe has been inspected. Next, the next pipe is inspected, and the data update unit 405 updates the data. Then, a command is sent to the signal sending unit 406 to send an update signal, indicating that the contact data has been updated to the next pipe. The feature scanning module 400 sends a command to the data storage module 500, which in turn sends a command to the data scanning unit 501.
