Description

Technical Field

[0001] This application relates to the field of pipeline flaw detection equipment technology, specifically a tooling for phased array testing. Background Technology

[0002] Pipeline flaw detection equipment is a specialized non-destructive testing device used to detect internal or surface defects in pipelines. Its core function is to identify cracks, corrosion, inclusions, weld defects, etc. in pipelines through non-destructive means, ensuring the safe operation of pipelines. It detects potential defects by means of physical methods (such as sound waves, electromagnetic, and radiation) without damaging the pipeline structure.

[0003] Ultrasonic phased array testing equipment for pipeline circumferential welds is widely used in the field of pipeline flaw detection technology. However, when using this equipment to inspect the circumferential welds of overhead pipelines, ensuring that the equipment can be stably fixed on the pipeline under test is an urgent problem to be solved.

[0004] Therefore, this application provides a tooling for phased array detection to solve the above problems. Utility Model Content

The first stud and the second stud are respectively screwed with a first wing nut and a second disc nut for pressing the two ends of the second C-shaped retaining ring toward the first C-shaped retaining ring.

[0008] Preferably, a lateral extension plate that is telescopically connected to the base plate is fixedly connected to the lateral moving plate, and a lateral telescopic groove that is slidably connected to the lateral extension plate is provided on the side of the base plate. The end of the first wing screw extends into the lateral telescopic groove to lock the lateral extension plate by contacting the bottom surface of the lateral extension plate.

[0009] Preferably, a longitudinal extension plate that is telescopically connected to the base plate is fixedly connected to the longitudinal moving plate, and a longitudinal telescopic groove that is slidably connected to the longitudinal extension plate is provided on the side of the base plate.

[0011] Preferably, the base plate, the transverse fixing plate, the transverse moving plate, the longitudinal fixing plate, and the longitudinal moving plate all have rubber anti-slip pads on their surfaces.

[0012] Preferably, a sunshade is connected to the longitudinally moving plate via a damping hinge.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] This embodiment provides a tooling for phased array detection, such as... Figures 1-2 As shown, the tooling for phased array testing includes a base plate 1 and four transverse fixing plates 2, transverse moving plates 3, longitudinal fixing plates 4, and longitudinal moving plates 5 arranged on the four sides of the base plate 1 for clamping the phased array testing equipment. The transverse fixing plates 2 and longitudinal fixing plates 4 are fixedly connected to adjacent sides of the base plate 1. The transverse moving plates 3 are telescopically connected to the side of the base plate 1 away from the transverse fixing plates 2. The longitudinal moving plates 5 are telescopically connected to the side of the base plate 1 away from the longitudinal fixing plates 4. The bottom of the base plate 1 is screwed with a first wing screw 6 and a second wing screw 7 for locking the transverse moving plates 3 and the longitudinal moving plates 5 on the base plate 1 respectively. The bottom of the base plate 1 is also rotatably provided with a clamping ring composed of a first C-shaped retaining ring 8 and a second C-shaped retaining ring 9 for installation and fixing on the pipeline.

[0018] In use, place the phased array detection equipment on the base plate 1, close to the horizontal fixed plate 2 and the vertical fixed plate 4. Slide the horizontal moving plate 3 and the vertical moving plate 5 to press them against the corresponding sides of the detection equipment. Tighten the first wing screw 6 and the second wing screw 7 to lock the position of the moving plates, thus completing the four-way clamping and fixing of the detection equipment. Then, open the first C-shaped retaining ring 8 and the second C-shaped retaining ring 9 of the clamping ring and fit them onto the surface of the pipe to be tested. Then, lock the first C-shaped retaining ring 8 and the second C-shaped retaining ring 9 again. Finally, start the phased array detection equipment. With the stable fixing of the tooling, a single person can efficiently complete the scanning of circumferential weld defects.

[0019] Specifically, the first C-shaped retaining ring 8 is rotatably connected to the bottom surface of the base plate 1 near the transverse fixed retaining plate 2. The first C-shaped retaining ring 8 is fixedly connected to the two ends of the first C-shaped retaining ring 9 by the first stud 10 and the second stud 12, which pass through the two ends of the second C-shaped retaining ring 9. The first stud 10 and the second stud 12 are respectively screwed with the first wing nut 11 and the second wing nut 13 for pressing the two ends of the second C-shaped retaining ring 9 towards the first C-shaped retaining ring 8. During installation, the first C-shaped retaining ring 8 and the second C-shaped retaining ring 9 are fitted onto the pipe surface. By rotating the first wing nut 11 and the second wing nut 13, the second C-shaped retaining ring 9 moves along the stud towards the first C-shaped retaining ring 8 until the retaining ring is tightly fitted to the outer wall of the pipe, forming a closed and fixed structure. The wing nut can be manually adjusted without tools, which is highly efficient for single-person operation. The arc structure of the C-shaped retaining ring has a high degree of fit with the pipe surface. The nut can be adjusted to adapt to pipes of different diameters.

[0020] Specifically, a transverse extension plate 31 that is telescopically connected to the base plate 1 is fixedly connected to the transverse moving plate 3, and a transverse telescopic groove 101 that is slidably connected to the transverse extension plate 31 is provided on the side of the base plate 1. The end of the first wing screw 6 extends into the transverse telescopic groove 101 to lock the transverse extension plate 31 by contacting the bottom surface of the transverse extension plate 31. During adjustment, the first wing screw 6 is loosened and the transverse moving plate 3 is pushed to move along the transverse telescopic groove 101. After locking, the first wing screw 6 is tightened so that its end presses against the bottom surface of the transverse extension plate 31 and the position is fixed by friction.

[0021] Specifically, a longitudinal extension plate 51 that is telescopically connected to the base plate 1 is fixedly connected to the longitudinal moving plate 5, and a longitudinal telescopic groove 102 that is slidably connected to the longitudinal extension plate 51 is provided on the side of the base plate 1. The end of the second butterfly screw 7 extends into the longitudinal telescopic groove 102 to lock the longitudinal extension plate 51 by contacting the bottom surface of the longitudinal extension plate 51. The adjustment method is the same as that of the transverse moving plate 3. After loosening the second butterfly screw 7 and sliding the longitudinal moving plate 5 to the appropriate position, the screw is tightened to lock the plate by pressing the end against the bottom surface of the longitudinal extension plate 51.

[0022] It should be noted that the horizontal telescopic groove 101 and the vertical telescopic groove 102 are arranged side by side to avoid mutual interference. The first wing screw 6 is located on the side of the vertical telescopic groove 102 to avoid mutual interference, and the second wing screw 7 is located on the side of the horizontal telescopic groove 101 to avoid mutual interference. This avoids the horizontal and vertical adjustment mechanisms from overlapping in space. When adjusting the horizontal plate, the vertical screw will not touch the telescopic groove, and vice versa, thus improving the smoothness of single-person operation.

[0023] Furthermore, the base plate 1, as well as the surfaces of the transverse fixed plate 2, transverse moving plate 3, longitudinal fixed plate 4, and longitudinal moving plate 5, are all equipped with rubber anti-slip pads. The high coefficient of friction of the rubber enhances the contact force with the detection equipment, absorbs equipment vibrations during detection, such as the micro-vibrations during phased array probe scanning, reduces false signal interference, and improves detection accuracy.

[0024] Furthermore, a sunshade 14 is connected to the longitudinally moving plate 5 via a damping hinge; this shields the screen of the detection equipment from direct sunlight, preventing meter reading errors and operational misjudgments caused by glare. The damping hinge also allows the sunshade 14 to rotate freely and stay at any angle, making it convenient for one person to operate with one hand.

[0025] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
