Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic pipeline detection technology, specifically to an auxiliary tooling for ultrasonic pipeline testing that fits snugly. Background Technology
[0002] Ultrasonic testing is widely used in pipeline production, primarily for detecting internal defects and structural anomalies. In pipeline manufacturing, ultrasonic testing is mainly used to detect defects such as weld quality, wall thickness variations, cracks, and inclusions. According to a search, the announcement number is CN221825189U. The patent discloses a special ultrasonic flaw detection device for pipelines. In use, the pipeline to be tested is first placed inside the pipeline flaw detection frame, and then the ultrasonic probe is fixed inside the mounting sliding block. The drive motor is started, driving the first drive screw to rotate. The first drive screw drives the mounting sliding block to move along the direction of the first guide rod, thus allowing the ultrasonic probe to move stably. This avoids the need for workers to hold the ultrasonic probe for extended periods, which consumes a lot of physical strength and reduces detection efficiency. It also prevents missed detections due to the instability of the ultrasonic probe held by the worker. However, each time a test is performed, the pipeline needs to be mounted on the pipeline flaw detection frame. Although this facilitates relatively accurate, close-fitting pipeline inspection, it requires moving the pipeline up and down each time, which is quite laborious. Therefore, an auxiliary tooling for close-fitting ultrasonic pipeline inspection is designed that can directly inspect the pipeline without the need for special pipeline handling, saving on handling costs and avoiding safety issues caused by handling. It can also be easily moved along the length of the pipeline, facilitating multi-point inspection of the pipeline and further improving inspection efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary tooling for ultrasonic testing of pipelines that fits snugly. It can directly test pipelines without the need for special handling of the pipelines, saving on handling costs and avoiding safety issues caused by handling. At the same time, it can be easily moved along the length of the pipeline, facilitating the testing of multiple points on the pipeline and further improving testing efficiency.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tooling for ultrasonic testing of fitting pipes, comprising a pipe hook, an ultrasonic detector, and three sets of moving mechanisms disposed inside the pipe hook and distributed toward the center. Two sets of moving mechanisms are coaxially and symmetrically disposed at the top of the pipe hook and the spacing is adjustable. The other set of moving mechanisms is disposed at the inner bottom of the pipe hook and can be lifted and lowered. The ultrasonic detector is located on one side of the moving mechanism at the bottom and can be lifted and lowered independently.
[0007] Preferably, the moving mechanism includes at least two sets of pipe-driving wheels distributed front and rear. The top of the pipe hook is configured as a guide arc segment. The two sets of moving mechanisms at the top are guided and slidably engaged with the guide arc segment via guide arc blocks. The pipe-driving wheels are mounted on the guide arc blocks via connecting frames. Preferably, it also includes a spacing adjustment mechanism for adjusting the distance between the two sets of moving mechanisms at the top. The spacing adjustment mechanism includes a spacing adjustment track fixedly installed at the top of the guide arc segment. A bidirectional screw is rotatably connected to the spacing adjustment track. A spacing adjustment slider is symmetrically threaded onto the bidirectional screw and is guided and slidably engaged with the spacing adjustment track. Guide sleeves are provided at the bottom of both spacing adjustment sliders. Round shafts are fixedly installed on both sides of the guide arc blocks. The two round shafts are rotatably guided and slidably engaged with the two guide sleeves respectively. It also includes an adjustment drive assembly for driving the bidirectional screw to rotate. Preferably, the adjustment drive assembly includes a spacing adjustment drive motor fixedly installed on the spacing adjustment track. The output shaft of the spacing adjustment drive motor is driven and engaged with the bidirectional screw via a transmission assembly.
[0008] Preferably, the bottom of the pipe hook is vertically slidably fitted with a liftable lifting frame via a lifting drive cylinder. A pipe-driving wheel in the lower moving mechanism is mounted to the top of the lifting frame. The lifting frame is threadedly connected to a lifting adjustment screw with an adjustment cap fixedly attached to its bottom. A rotatably fitted mounting platform is provided at the top of the lifting adjustment screw.

[0009] (III) Beneficial Effects Compared with the prior art, this utility model provides an auxiliary tooling for ultrasonic testing of pipes with the following beneficial effects: This auxiliary tooling for ultrasonic testing of pipes, through a pipe hook and three sets of moving mechanisms, can directly put the pipe hook on the pipe and make the three sets of moving mechanisms wrap around the pipe. Then, it can move the ultrasonic detector to any point and then move the ultrasonic detector to the side of the pipe to fit the pipe, and then perform ultrasonic testing on the pipe. No additional handling operations are required, and it can be moved by hand, making the operation convenient and flexible. By adjusting the distance between the two sets of moving mechanisms located at the top, the distance between the two can be adjusted while ensuring coaxiality, thereby meeting the needs of clamping and further ultrasonic testing of pipes of different specifications. This auxiliary tooling for ultrasonic testing of pipes can directly test the pipe without the need to specially transport the pipe, saving transportation costs and avoiding safety issues caused by transportation. At the same time, it can be moved conveniently along the length of the pipe, facilitating the testing of multiple points on the pipe and further improving the testing efficiency.

[0017] 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 skilled in the art without creative effort are within the scope of protection of the present utility model. Embodiment: Please refer to Figures 1-6. An auxiliary tool for ultrasonic testing of fitting pipes includes a pipe hook 1, an ultrasonic detector 17, and three sets of moving mechanisms disposed inside the pipe hook 1 and distributed towards the center. Two sets of moving mechanisms are coaxially symmetrically disposed on the top of the pipe hook 1 and the spacing is adjustable. Another set of moving mechanisms is disposed at the inner bottom of the pipe hook 1 and can be raised and lowered. The ultrasonic detector 17 accompanies the moving mechanism at the bottom and can be raised and lowered independently.
[0018] Specifically, the moving mechanism includes at least two sets of pipe-driving wheels 2 distributed front and rear. The top of the pipe hook 1 is set as a guide arc segment 3. The two sets of moving mechanisms at the top are guided and slidably engaged with the guide arc segment 3 through the guide arc block 5. The pipe-driving wheels 2 are installed on the guide arc block 5 through the connecting frame 4. With at least two sets of pipe-driving wheels 2 distributed front and rear, the point can move on the outer wall of the pipe, improving the stability of movement. Through the setting of the connecting frame 4, the pipe-driving wheel 2 at the top has a moving distance from the guide arc segment 3, improving the convenience of adjustment.
[0019] Specifically, it also includes a spacing adjustment mechanism for adjusting the distance between the two sets of moving mechanisms located at the top. The spacing adjustment mechanism includes a spacing adjustment rail 7 fixedly installed at the top of the guide arc segment 3. A bidirectional screw 8 is rotatably connected to the spacing adjustment rail 7. A spacing adjustment slider 9 is symmetrically threaded onto the bidirectional screw 8 and slides in a guide-sliding engagement with the spacing adjustment rail 7. Guide sleeves 10 are provided at the bottom of each of the two spacing adjustment sliders 9. Round shafts 6 are fixedly installed on the guide arc blocks 5 on both sides. The two round shafts 6 slide in a rotatable guide-sliding engagement with the two guide sleeves 10 respectively. It also includes an adjustment drive assembly for driving the bidirectional screw 8 to rotate. By adjusting the drive assembly, the output shaft of the adjustment drive assembly rotates clockwise or counterclockwise, thereby driving the bidirectional screw 8 to rotate clockwise or counterclockwise, thereby driving the two spacing adjustment sliders 9 to move towards the center or to the sides, thereby driving the two guide sleeves 10 to move towards the center or to the sides. Through the cooperation of the guide sleeves 10 and the round shafts 6, it is convenient to drive the guide arc blocks 5 along the guide arc segment 3. It can be moved towards the center or to the sides, thereby adjusting the spacing between the two sets of moving mechanisms located at the top.
[0020] Specifically, the adjustment drive assembly includes an adjustment drive motor 11 fixedly mounted on the adjustment track 7. The output shaft of the adjustment drive motor 11 is connected to the bidirectional screw 8 via a transmission assembly 12. When the adjustment drive motor 11 is started, its output shaft rotates clockwise or counterclockwise. Through the transmission assembly 12, the bidirectional screw 8 can be driven to rotate clockwise or counterclockwise. Furthermore, the transmission assembly 12 can be configured as a sprocket and chain or a drive wheel and belt transmission. Specifically, the bottom of the pipe hook 1 is vertically slidably connected to a lifting frame 14 via a lifting drive cylinder 13. The pipe-driving wheel 2 in the lower moving mechanism is mounted on the top of the lifting frame 14. A lifting adjustment screw 18 with an adjustment cap fixed to its bottom is threaded onto the lifting frame 14. A rotating mounting platform 16 is provided on the top of the lifting adjustment screw 18. A guide rod 19, which slides vertically with the lifting frame 14, is fixedly mounted on the bottom of the mounting platform 16. The ultrasonic detector 17 is fixedly mounted on the top of the mounting platform 16. The lifting drive cylinder 13 facilitates the lifting of the lifting frame 14, thereby facilitating the overall lifting of the lower moving mechanism and the ultrasonic detector 17. By rotating the adjustment cap, the lifting adjustment screw 18 is threadedly connected to the lifting frame 14, and under the guidance of the guide rod 19, the ultrasonic detector 17 is lifted relative to the pipe-driving wheel 2 at the bottom. This allows the ultrasonic detector 17 to move while the pipe-driving wheel 2 is pressed against the outer wall of the pipe. Later, it also fits against the outer wall of the pipe. Furthermore, the bottom of the lifting frame 14 is fixedly installed with a guide strip that slides vertically with the bottom of the pipe hook 1 to further improve the stability of the lifting frame 14 during lifting. Specifically, a handle 20 is fixedly installed on the pipe hook 1. The handle 20 makes it convenient to hold the pipe hook 1 and avoids the situation where fingers bump against the outer wall of the pipe due to directly holding the pipe hook 1.
