During the process of the flaw detector operator pushing the scanning frame, the detection probe detects the pipeline weld, and the detection result is observed in real time by operating the display screen, so as to inspect the pipeline weld condition. However, due to the curved surface structure of the pipeline, it is difficult to fix the equipment, and the method of manually pushing the scanning frame to drive the probe for detection is prone to deviation, resulting in errors in the detection result.

[0026] As Figures 1 to 5 shown, a phased array ultrasonic pipeline scanning device provided by a specific embodiment of the present utility model includes a detection device main body 1, a detection probe 2 and a track ring 3. An activity component for automatically detecting by carrying the detection probe 2 is provided on the track ring 3. By setting the activity component, the detection probe 2 can be driven to automatically move and detect during the pipeline detection process, without the need for staff to manually push the scanning frame to drive the movement of the detection probe 2, thereby making the detection more accurate and with smaller errors. The activity component includes a moving frame 4 provided on the track ring 3 for driving the movement of the detection probe 2. Two pulleys 5 and a transmission member for driving the movement of the moving frame 4 are provided between the moving frame 4 and the track ring 3. By setting the transmission member, the moving frame 4 can be driven to move, so as to facilitate the moving frame 4 to drive the detection probe 2 to move. It also includes a clamping component provided on one side of the track ring 3 for fixing the track ring 3 on the pipeline. By setting the clamping component, when the entire device is used for detection, the track ring 3 can be clamped and fixed on the pipeline, that is, the entire device is fixed on the curved pipeline, facilitating subsequent detection.

[0027] As Figure 1 and Figure 4As shown in the figure, specifically, the clamping assembly includes a clamping frame 16, a sliding groove 17, a clamping plate 18, and a threaded rod 19. The clamping frame 16 is fixedly connected to the track ring 3. The sliding groove 17 is formed in the clamping frame 16, and the clamping plate 18 is slidably connected in the sliding groove 17. The threaded rod 19 is threadedly connected to the clamping plate 18. The clamping plate 18 is provided with an arc shape, and an anti-slip pad is provided on the arc shape. When detecting a pipeline, the entire device is placed on the pipeline, so that the pipeline passes through the track ring 3 and is located between the clamping plates 18. Rotate the threaded rod 19 to make the clamping plate 18 move towards the middle in the sliding groove 17 and gradually press against the outer wall of the pipeline, thereby clamping the pipeline. At this time, the clamping of the pipeline by the clamping plate 18 completes the limit fixation of the track ring 3 on the pipeline, that is, completes the clamping and fixation of the entire device on the pipeline. The threaded rod 19 is selected as a bidirectional threaded rod, so that the clamping plate 18 can move towards the middle or move towards both sides respectively when it rotates. The arc shape setting enables better fitting with the outer wall of the pipeline, making the fixation effect better. The clamping plate 18 is adjustable, further enabling the entire device to be fixed on pipelines with different diameters, so that there is an adjustable space for the clamping plate 18 for pipelines with different diameters, thus facilitating the limit fixation of the device.

[0028] As Figure 2 and Figure 4 shown in the figure, specifically, the moving frame 4 is provided with a long bolt 10 and a guide rod 11 for adjusting the position of the detection probe 2. The long bolt 10 is threadedly connected to the moving frame 4, and the guide rod 11 is slidably connected to the moving frame 4. The end of the long bolt 10 is rotatably connected to a connecting block 12, and the connecting block 12 is fixedly connected to the guide rod 11. An electric push rod 13 is fixedly installed on the connecting block 12, and the detection probe 2 is fixedly installed on the electric push rod 13. After the device is fixed, by starting the electric push rod 13 to drive the detection probe 2 to gradually approach the pipeline. At the same time, rotate the long bolt 10. With the cooperation of the guide rod 11, the long bolt 10 moves on the moving frame 4 and pushes the connecting block 12 to move, thereby pushing the electric push rod 13 on the connecting block 12 and the detection probe 2 at the bottom to move, and then specifically adjusting the position of the detection probe 2 according to the position of the weld on the pipeline, so that the position where the detection probe 2 is located is the best detection position.

[0029] As Figures 1 to 5As shown in the figure, specifically, a guiding groove 6 for the movement of the moving frame 4 is provided on the track ring 3. Two pulleys 5 are respectively slidably connected in the guiding groove 6 and at the edge of the track ring 3, and both pulleys 5 are rotatably connected to the moving frame 4. The transmission member includes a motor 7, a gear 8, and a gear ring 9. The motor 7 is fixedly installed on the moving frame 4, the gear 8 is fixedly connected to the output shaft of the motor 7, the gear ring 9 is fixedly installed on the track ring 3, and the gear ring 9 meshes with the gear 8. The detection device body 1 is fixedly installed on the track ring 3. A short rod 14 is rotatably connected to the moving frame 4. A limiting groove 15 for cooperating with the short rod 14 to limit the movement of the moving frame 4 is formed on the track ring 3, and the short rod 14 is slidably connected in the limiting groove 15. After adjusting the position of the detection probe 2, the motor 7 is started to drive the gear 8 to rotate. Thus, the gear 8 meshes and rotates on the gear ring 9. Furthermore, under the cooperative action of the pulleys 5 and the guiding groove 6, the moving frame 4 moves on the track ring 3. The pulleys 5 slide in the guiding groove 6, and the short rod 14 slides in the limiting groove 15. Thus, the limiting groove 15 is used to exert a limiting effect on the moving frame 4. The movement of the moving frame 4 on the track ring 3 drives the detection probe 2 to move through components such as long bolts 10. The entire movement process is a circular movement, so that the detection probe 2 follows a circular motion, and then the welds on the pipeline are detected. The detection probe 2 is connected to the detection device body 1 through a wire. The detection situation of the weld can be observed in real time through the detection device body 1. After rotating one week, the motor 7 can be reversely driven so that the moving frame 4 can move reversely for detection again. During the process of rotating one week and then rotating reversely, the movement of the wire between the detection probe 2 and the detection device body 1 does not cause entanglement or other effects on the device. After the detection is completed, the threaded rod 19 is rotated reversely so that the clamping plate 18 is separated from the outer wall of the pipeline, and then the entire device can be removed.
