Technical Field

[0001] This utility model relates to the field of ultrasonic testing device technology, and in particular to a phased array ultrasonic testing device for PE pipe electrofusion joints. Background Technology

[0002] The basic idea of ​​phased-array ultrasonic testing comes from radar electromagnetic wave phased array technology. Phased-array radar is composed of many radiating elements arranged in an array. By controlling the amplitude and phase of each element in the array antenna, the radiation direction of electromagnetic waves is adjusted, and a flexible and fast focused radar beam is synthesized within a certain spatial range. The detection principle of phased-array ultrasonic testing devices is basically the same.

[0003] Currently, due to the bending of some PE pipes, the existing phased array ultrasonic testing device for PE pipe electrofusion joints is inconvenient to place during use, making it difficult to test the PE pipes. In addition, since the phased array ultrasonic testing device for PE pipe electrofusion joints cannot be adjusted in angle during use, the testing results may be inaccurate. Utility Model Content

[0012] Preferably, one end of the rocker arm is fixedly connected to a threaded rod, and the surface of the threaded rod is threaded with a support foot, which is slidably connected to the inner wall of the outer bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The phased array ultrasonic testing device for the PE pipe electrofusion joint can rotate the ultrasonic testing device by shaking the positioning rod, thereby adjusting the angle of the ultrasonic testing device so that the ultrasonic testing device can better scan the connection of the PE pipe.

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a phased array ultrasonic testing device for PE pipe electrofusion joints, including an upper ring 1, a fixed rod 17 fixedly connected to one side of the upper ring 1, a lower ring 2 rotatably connected to the surface of the fixed rod 17, toothed rings 3 fixedly connected to the surfaces of both the upper ring 1 and the lower ring 2, a sliding groove 8 opened on the surface of both the upper ring 1 and the lower ring 2, a sliding plate 9 slidably connected to the inner wall of the sliding groove 8, a motor 6 fixedly mounted on the surface of the sliding plate 9, a gear 7 fixedly connected to the output shaft of the motor 6, the gear 7 meshing with the toothed ring 3, a fixed frame 10 fixedly connected to the surface of the sliding plate 9, a fixed plate 11 fixedly connected to the surface of the fixed frame 10, and an ultrasonic testing device 16 rotatably connected to the inner wall of the fixed plate 11.

[0026] The toothed rings 3 on the upper ring 1 and the lower ring 2 are interconnected, and the sliding grooves 8 on the upper ring 1 and the lower ring 2 are interconnected. First, the upper ring 1 and the lower ring 2 are closed to fix the PE pipe. Then, the starting motor 6 drives the gear 7 to rotate. When the gear 7 rotates, it meshes with the toothed ring 3 and moves along the toothed ring 3. When the gear 7 moves, it drives the motor 6 and the sliding plate 9 to move. When the sliding plate 9 moves, it drives the fixing frame 10 to move. When the fixing frame 10 moves, it drives the ultrasonic testing device 16 to move. At this time, the ultrasonic testing device 16 rotates around the connection of the PE pipe, thereby allowing the ultrasonic testing device 16 to test the connection of the PE pipe. By starting the motor 6 to drive the ultrasonic testing device 16 to rotate around the PE pipe, the manual rotation of the ultrasonic testing device 16 is saved.

[0027] The surface of the fixed plate 11 is provided with positioning holes 13, which are arranged in a ring. The ultrasonic testing device 16 is fixedly connected to a rocker arm 12, which is rotatably connected to the inner wall of the fixed plate 11. The inner wall of the rocker arm 12 is slidably connected to a positioning rod 14, which is slidably connected to the inner wall of the positioning hole 13. A spring 15 is sleeved on the surface of the positioning rod 14, and the two ends of the spring 15 are fixedly connected to the surfaces of the positioning rod 14 and the rocker arm 12, respectively.

[0028] Pulling the positioning rod 14 causes it to slide out of the positioning hole 13. As the positioning rod 14 slides, it compresses the spring 15. Then, shaking the positioning rod 14 causes the rocker arm 12 to rotate, which in turn rotates the ultrasonic testing device 16. After adjusting the ultrasonic testing device 16, releasing the positioning rod 14 causes the spring 15 to slide the positioning rod 14 into the positioning hole 13, thus securing the ultrasonic testing device 16. Shaking the positioning rod 14 then rotates the ultrasonic testing device 16, adjusting its angle to better scan the PE pipe connection. Adjusting the scanning angle of the ultrasonic testing device 16 makes the detection results more accurate.

[0029] An outer bracket 4 is fixedly connected to one side of the lower ring 2. A rocker arm 5 is rotatably connected to the inner wall of the outer bracket 4. A threaded rod 19 is fixedly connected to one end of the rocker arm 5. A support leg 18 is threadedly connected to the surface of the threaded rod 19. The support leg 18 is slidably connected to the inner wall of the outer bracket 4.

[0030] By shaking the rocker arm 5, the threaded rod 19 is driven to rotate. When the threaded rod 19 rotates, the support leg 18 slides out along the inner wall of the outer bracket 4. At this time, by shaking the rocker arm 5, the support leg 18 can slide out to support the upper ring 1 and the lower ring 2. When the PE pipe is bent, the height of the upper ring 1 and the lower ring 2 can be increased by sliding the support leg 18 out, so that there is a larger space between the PE pipe and the surface. This allows the ultrasonic testing device 16 to smoothly test the connection of the PE pipe, making it easier for workers to operate and making the testing more convenient.

[0031] Working principle: The toothed rings 3 on the upper ring 1 and the lower ring 2 are interconnected, and the sliding grooves 8 on the upper ring 1 and the lower ring 2 are interconnected. First, the upper ring 1 and the lower ring 2 are closed to fix the PE pipe. Then, the starting motor 6 drives the gear 7 to rotate. When the gear 7 rotates, it meshes with the toothed ring 3 and moves along the toothed ring 3. When the gear 7 moves, it drives the motor 6 and the sliding plate 9 to move. When the sliding plate 9 moves, it drives the fixing frame 10 to move. When the fixing frame 10 moves, it drives the ultrasonic testing device 16 to move. At this time, the ultrasonic testing device 16 rotates around the connection of the PE pipe, thereby allowing the ultrasonic testing device 16 to detect the connection of the PE pipe. By starting the motor 6 to drive the ultrasonic testing device 16 to rotate around the PE pipe, the manual rotation of the ultrasonic testing device 16 is saved.

[0032] By pulling the positioning rod 14, the positioning rod 14 slides out of the positioning hole 13. At this time, the positioning rod 14 compresses the spring 15 as it slides. Then, by shaking the positioning rod 14, the rocker arm 12 is rotated. When the rocker arm 12 rotates, it drives the ultrasonic testing device 16 to rotate. After the ultrasonic testing device 16 is adjusted, the positioning rod 14 is released. At this time, the spring 15 uses its elasticity to drive the positioning rod 14 to slide into the positioning hole 13 for locking, thereby fixing the ultrasonic testing device 16.

[0033] By shaking the rocker arm 5, the threaded rod 19 is driven to rotate. When the threaded rod 19 rotates, the support leg 18 slides out along the inner wall of the outer bracket 4. At this time, by shaking the rocker arm 5, the support leg 18 can slide out and support the upper ring 1 and the lower ring 2. This is especially useful when the PE pipe is bent.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
