Description

Technical Field

[0001] The utility model belongs to the technical field of non-destructive testing, and in particular relates to a phased array testing device. Background Art

[0002] Phased arrays, or phase-controlled arrays, control the beam direction by adjusting the phase of each array element. In weld measurement, phased arrays can acquire real-time information about the weld's geometry, location, shape, and other characteristics, enabling precise measurement. Pressure vessels typically have insert fillet welds on their upper ends. These welds are created by inserting a pipe into a pipe socket through welding. This involves drilling a hole in the pipe socket or vessel cover, inserting the pipe into the hole, and securing the pipe with welding.

[0003] In the existing phased array inspection process, a handheld ultrasonic phased array probe is generally used to rotate along the weld to complete a comprehensive scan of the inserted fillet weld. However, the ultrasonic phased array probe is usually rotated manually, which is not only inconvenient to operate, but also prone to deviation when manually rotating the ultrasonic phased array probe, making the data obtained by the ultrasonic phased array probe unstable, that is, the data obtained by the probe is unreliable.

[0004] In summary, the existing way of moving the handheld probe leads to unreliable phased array detection results. Utility Model Content

[0035] Phased array detection device embodiment:

[0036] like Figure 1-5 As shown, the phased array detection device includes a mover 1, a bracket 2, a lifting assembly 3, a probe 5 clamping assembly and a controller; the mover 1 is connected to the bracket 2 through the lifting assembly 3, and the other end of the bracket 2 is connected to the probe 5 clamping assembly, so that the bracket 2 can drive the probe 5 clamping assembly to move when it moves.

[0037] In order to realize the autonomous movement of the device, the traveler 1 includes a vehicle body 11, a permanent magnet 12 for adsorbing the vehicle body 11 on the outer wall of the pipe, and a driving mechanism for driving the vehicle body 11 to crawl. The traveler 1 is adsorbed to the pipe by the permanent magnet 12, and the movement of the traveler is realized by the cooperation between the vehicle body 11 and the driving mechanism. Figure 4 As shown, in order to ensure that the vehicle body 11 can move smoothly, there are two permanent magnets 12, which are respectively arranged at both ends of the vehicle body 11 to achieve balance of the vehicle body 11.

[0038] In order to achieve controlled movement of the mover 1, a controller is connected to the start / stop switch of the drive mechanism to control the mover 1 to move circumferentially along the outer wall of the pipeline. The controller uses a single chip microcomputer.

[0039] like Figure 3 As shown, in order to facilitate the bracket 2 to support the probe 5 to the corresponding position, the above-mentioned bracket 2 includes a horizontal support rod 21 and an oblique support rod 22. One end of the above-mentioned horizontal support rod 21 is connected to the lifting assembly 3, and the other end is fixedly connected to one end of the oblique support rod 22. The other end of the oblique support rod 22 is connected to the probe 5 clamping assembly; the above-mentioned probe 5 clamping assembly is used to clamp the probe 5 of the phased array detector 7; the probe 5 is connected to the phased array detector 7 through a signal line to realize the detection of the inserted fillet weld 8 on the pipeline.

[0040] like Figure 6As shown, since the door on the pipe of the pressure vessel may be provided with an opening or some protruding parts, which affect the movement of the traveler 1, the traveler 1 needs to avoid these obstructing parts, resulting in an inconsistent distance between the traveler 1 and the inserted fillet weld 8. However, the distance between the probe 5 and the inserted fillet weld 8 needs to be consistent. Therefore, the lifting assembly 3 is used to adapt to the different distances between the traveler 1 and the inserted fillet weld 8 to ensure that the device can be applied to different pipes. Specifically, the lifting assembly 3 includes a lifting shell 31, a rack 32, a gear 33, a gear shaft 34, an upper limit plate 35, a lower limit plate 36, a baffle 37 and a connecting plate 38 for connecting to the horizontal support rod 21; a connecting opening is provided on the side wall of the lifting shell 31, and the connecting plate 38 partially passes through the connecting opening and is fixedly connected to the horizontal support rod 21, ensuring that the connecting plate 38 and the horizontal support rod 21 can move synchronously. The rack 32 is fixed to the inside of the connecting plate 38. The gear 33 is rotatably connected to the inner wall of the lifting housing 31 via a gear shaft 34. The gear 33 meshes with the rack 32, and the connecting plate 38 moves up and down by rotating the gear shaft 34. The end of the gear shaft 34 extending from the slide slot is fixedly connected to an adjustment knob 39. Since the gear 33 is fixed, when the adjustment knob 39 is rotated, the gear 33 drives the rack 32 to move, the rack 32 drives the connecting plate 38 to move, and the connecting plate 38 drives the horizontal support rod 21 to move. In other words, the up and down movement of the bracket 2 can be controlled by the adjustment knob 39. The upper end of the connecting plate 38 is connected to the baffle 37. The upper limit plate 35 and the lower limit plate 36 are disposed on the inner wall of the lifting housing 31 opposite the connecting plate 38. The upper limit plate 35 and the lower limit plate 36 limit the baffle 37 to prevent the rack 32 from disengaging from the gear 33 due to excessive adjustment of the adjustment knob 39.

[0041] To prevent the signal cable from affecting the probe 5 during movement, a cable grommet 23 is provided on the outside of the oblique support rod 22 for the probe 5's signal cable to pass through. The cable grommet 23 protects the probe 5's signal cable, ensuring stable and reliable signal transmission. By routing the cables neatly through the cable grommet 23, the area around the probe 5 remains tidy, making management and maintenance easier.

[0042] like Figure 1 、 Figure 2 As shown, the other end of the oblique support rod 22 is connected to the probe 5 clamping assembly via an infinitely rotatable member 6. Because the probe 5 clamping assembly is suitable for clamping the probe 5, the weight of the probe 5 clamping assembly ensures that the probe 5 and the probe 5 clamping assembly always remain in a vertically downward position. Since the inserted fillet weld 8 is always located below the probe 5, this further ensures that the probe 5 can reliably scan the inserted fillet weld 8. Furthermore, the probe 5 clamping assembly allows for flexible adjustment of angle and position, facilitating operation when clamping the probe 5.

[0043] Furthermore, the unlimited rotating member 6 includes a rotating rod 61 and a rotating ring 62 . The rotating rod 61 is horizontally connected to the end of the oblique supporting rod 22 , and the rotating ring 62 is connected to the upper end of the clamping member of the probe 5 .

[0044] To accommodate probes 5 of varying sizes, the probe 5 clamp utilizes a spring clamp 4. The spring clamp 4 comprises a clamping portion 41, a spring portion, a connecting portion, and a paddle 42. The spring portion is connected to the clamping portion 41 via the connecting portion, and the paddle 42 is connected to the spring portion. By moving the paddle 42 left or right, the clamping width of the clamping portion 41 can be adjusted. The design of the spring clamp 4 allows for adjustment of the clamping width of the probe 5.

[0045] like Figure 1 As shown, when the present invention is used, the device is placed directly on the pipe of the inserted fillet weld 8, the probe 5 is clamped to the probe 5 clamping assembly, the distance between the probe 5 and the inserted fillet weld 8 is adjusted by adjusting the knob 39, the phased array detector 7 is turned on, and the start and stop switch of the driving mechanism of the mover 1 is controlled by the controller to start, so that the mover 1 starts to move, thereby realizing the detection of the inserted fillet weld 8.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
