Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically a pipeline phased array inspection device. Background Technology

[0002] The pipeline phased array inspection device is an advanced equipment that uses phased array ultrasonic technology to perform non-destructive testing on pipelines. It controls the excitation timing of multiple ultrasonic crystals to achieve the deflection, focusing and scanning of the sound beam, thereby efficiently detecting defects such as welds, corrosion and cracks in pipelines.

[0003] In the current testing equipment, when manually scanning the phased array ultrasonic test, the outer side of the pipeline is over-utilized with a flat surface for encoder verification, resulting in significant errors. Typically, the encoder is connected to a probe wedge and manually advanced. However, it is difficult to maintain good coupling between the wedge and the workpiece being inspected, requiring repeated confirmation of the scanning quality, which reduces the overall testing efficiency. Furthermore, the wedge offset from the weld centerline during scanning has a large error, leading to inaccurate image positioning and making pipeline inspection and evaluation extremely difficult. Optimization and improvement are needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figure 1 - Figure 5 As shown, this application provides a pipeline phased array detection device, including: a flexible guide rail 1, a locking buckle 4 on the outer side of the flexible guide rail 1, and an I-shaped sliding block 9 connected to the inner side of the flexible guide rail 1; it also includes a detection fitting component and a snap-fit ​​adjustment component: the detection fitting component includes a telescopic measuring ruler 10, which is disposed on one side of the I-shaped sliding block 9, and a probe connecting block 12 is connected to one side of the telescopic measuring ruler 10; an elastic connector 13 is connected to the inner side of the probe connecting block 12; and a probe body 15 is disposed at the bottom end of the probe connecting block 12. The detection fitting component is used to tightly fit the probe body 15 into the pipeline; the snap-fit ​​adjustment component includes a pressing block 6, which is connected to the inner side of the locking buckle 4, and an elastic connecting rod 7 is connected to the inner side of the pressing block 6; a limit insertion post 8 is connected to the outer side of the pressing block 6. The snap-fit ​​adjustment component is used for snap-fit ​​positioning of the flexible guide rail 1 and the locking buckle 4.

[0023] Specifically, such as Figure 2 As shown, the flexible guide rail 1 has a sliding groove 2 inside, and a scale measuring ruler 3 is connected to the outside of the flexible guide rail 1. The sliding groove 2 is used for the circumferential sliding of the I-shaped sliding block 9, and the scale measuring ruler 3 is used to determine the position of the I-shaped sliding block 9.

[0024] Specifically, such as Figure 4As shown, a guide rod 11 is connected to one side of the top of the telescopic measuring ruler 10. The probe connecting block 12 is set at the bottom of the outer side of the guide rod 11. The probe connecting block 12 slides on the outer side of the guide rod 11 to control the orientation. An elastic connector 13 is set on the inner side for elastic connection.

[0025] Specifically, such as Figure 4 As shown, a locking pin 14 is connected to one side of the probe connecting block 12, and there are two locking pins 14. A locking groove is provided at the bottom inner side of the probe connecting block 12. The locking groove facilitates the locking and positioning of the probe body 15 at the bottom. The locking pin 14 at the end is used for positioning the probe body 15.

[0026] Specifically, such as Figure 5 As shown, one end of the probe body 15 is connected to a threaded connecting post 19, and a rotating frame 16 is connected to the outside of the threaded connecting post 19. The threaded connecting post 19 is configured to be half threaded and half smooth. The threaded part is used to connect to the probe body 15 for positioning, and the smooth part is used to connect to the rotating frame 16, so that the rotating frame 16 can be manually rotated for adjustment.

[0027] Specifically, such as Figure 5 As shown, an elastic connecting rod 17 is connected to one end of the inner side of the rotating frame 16, and a positioning hook 18 is connected to one side of the elastic connecting rod 17. The elastic connecting rod 17 is connected to one end of the inner side of the rotating frame 16, and the positioning hook 18 is slidably connected to the inner side of the two outer walls of the rotating frame 16. The elastic connecting rod 17 is fixedly connected to the positioning hook 18. One end of the spring on the elastic connecting rod 17 is fixedly connected to the inner side of the positioning hook 18, and the other end is fixedly connected to one side of the inner wall of the rotating frame 16. The elastic force of the spring is used as the reverse force for pulling the positioning hook 18, which makes it easy to adjust the positioning hook 18 to hang on the locking pin 14 to limit the probe body 15.

[0028] Specifically, such as Figure 3 As shown, the inner wall of the locking buckle 4 is provided with a movable groove 5. The movable groove 5 is used to guide the movement of the extrusion block 6, so as to facilitate the control of the extrusion block 6 to position the other end of the flexible guide rail 1.

[0029] Specifically, such as Figure 3 As shown, the elastic connecting rod 7 is fixedly connected to the pressing block 6, and the elastic connecting rod 7 is elastically connected to the locking buckle 4. The two ends of the outer spring of the elastic connecting rod 7 are fixedly connected to the outer wall of the locking buckle 4 and the inner side of the pressing block 6, respectively. After the pressure applied to the pressing block 6 is removed, the spring returns to its original position. When the elastic connecting rod 7 is in its initial position, the pressing block 6 is attached to the inner wall of the locking buckle 4. After pressing, the end of the pressing block 6 can be controlled to move inward, which facilitates convenient positioning of the flexible guide rail 1.

[0030] In this embodiment: the I-shaped sliding block 9 is set inside the flexible guide rail 1 to move in a ring, which facilitates all-round scanning. In order to improve the tightness of the fit between the probe body 15 and the pipe, the probe body 15 is designed to be easy to remove and adapt to pipes of different sizes. The telescopic measuring ruler 10 and the probe connecting block 12 installed on the probe body 15 are elastically connected, so that the probe body 15 has a pressure to fit the pipe, making it closer to the pipe during the detection process. When the flexible guide rail 1 is fitted to the pipe for connection, the other end of the flexible guide rail 1 is locked inside the locking buckle 4. Then the extrusion block 6 is pushed to continue to extrude the end of the flexible guide rail 1, so that the limiting insertion post 8 is inserted inside the flexible guide rail 1 and exits from the outside of the locking buckle 4 for positioning.

[0031] The specific steps of this scheme are as follows: When performing phased array testing on a pipeline, firstly, the flexible guide rail 1 is placed around the pipeline in a circular motion. The length of the flexible guide rail 1 is selected according to the diameter of the pipeline. Then, the other end of the flexible guide rail 1 is locked inside the locking buckle 4. At this time, the extrusion block 6 is pushed, and the elastic connecting rod 7 is compressed, allowing the end of the flexible guide rail 1 to continue to be compressed, so that the limiting insertion post 8 is inserted inside the flexible guide rail 1 and exits from the outside of the locking buckle 4. Then, the elastic connecting rod 7 is reset, the extrusion block 6 is moved out for positioning, and then the I-shaped sliding block 9 slides to the zero position of the scale measuring ruler 3 and moves around the inner side of the slide groove 2 to facilitate the probe body 15 to perform annular contact testing. To improve the probe body's performance... The tightness of the fit of the probe body 15 can be adjusted according to the pipe diameter. The positioning hook 18 is pulled outward to displace the elastic connecting rod 17, and then the positioning hook 18 disengages from the locking pin 14. At this time, the probe body 15 can slide out from the inside of the probe connecting block 12 for replacement. Conversely, it can be installed and fixed. The inner side of the probe connecting block 12 is provided with an elastic connector 13 to facilitate the elastic connection between the probe connecting block 12 and the telescopic measuring ruler 10. The movement of the probe connecting block 12 is guided by the guide rod 11 to control and adjust the position, so that the probe body 15 has a pressure that fits the pipe, so that it always stays close to the pipe during the detection process, ensuring the accuracy of the detection data.
