Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology for pipes, and in particular to an ultrasonic testing device for pipes. Background Technology

[0002] In the field of pipe manufacturing and quality control, ultrasonic testing technology is widely used due to its non-destructive nature, high precision, and high efficiency. This technology analyzes key parameters such as internal defects, thickness variations, and material uniformity of pipes by emitting ultrasonic waves into the pipe and receiving the reflected signals.

[0003] Traditional ultrasonic testing equipment often uses probes and clamps of fixed sizes, making it difficult to flexibly adapt to pipes of different diameters. This results in the need to frequently change probes or adjust equipment configurations during testing, which is not only cumbersome but also increases testing costs and time. Furthermore, the integrity testing of circular pipes requires comprehensive coverage of any potential defects on their inner and outer walls and circumference. Most existing equipment can only provide ultrasonic scanning at fixed angles or within a limited range, failing to achieve omnidirectional, blind-angle-free testing of pipes. It also presents difficulties in achieving 360-degree circumferential rotational testing of pipes. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide an ultrasonic testing device for pipes, so as to solve the current technical problem that it is difficult to flexibly adapt to pipes of different diameters and to achieve 360-degree circumferential rotation testing of pipes.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An ultrasonic testing device for pipes includes a chassis with an arc-shaped groove, an arc-shaped guide strip inside the arc-shaped groove of the chassis, a sliding cavity on the arc-shaped guide strip, an arc-shaped drive strip slidably mounted on the arc-shaped guide strip through the sliding cavity, and a testing body fixed on the inner wall surface of the arc-shaped drive strip.

[0008] Both ends of the arc-shaped guide strip are equipped with drive components for driving the arc-shaped drive strip to rotate. The drive components include gears rotatably mounted on the ends of the arc-shaped guide strip and arc-shaped racks mounted on the arc-shaped drive strip, with the gears meshing with the arc-shaped racks. The arc-shaped guide strip has connecting slots on both ends facing outward for the gears to pass through.

[0009] As an improved technical solution, an electric telescopic rod is fixed inside the chassis, and a lifting frame is fixedly connected to the movable end of the electric telescopic rod. One side of the lifting frame is fixedly connected to the outer wall of the arc-shaped guide strip.

[0010] As an improved technical solution, the drive assembly further includes two shaft brackets fixed to the ends of the arc-shaped guide strip, with a mounting shaft rotatably mounted between the two shaft brackets, and a gear sleeved on the mounting shaft.

[0011] As an improved technical solution, a pad is fixed on the side of the shaft bracket away from the arc-shaped guide strip, and a drive motor for driving the mounting shaft to rotate is fixed on the top of the pad, and the drive end of the drive motor is connected to one end of the mounting shaft.

[0012] As an improved technical solution, arc-shaped limiting cavities are provided on both sides of the arc-shaped drive strip, and multiple limiting wheels are rotatably installed on both sides of the inner wall of the arc-shaped guide strip along the direction of the limiting cavity, with the rolling end of the limiting wheel located inside the limiting cavity.

[0013] As an improved technical solution, the outer wall of the arc-shaped drive bar has a mounting cavity in the middle that communicates with the connecting groove, and the arc-shaped rack is fixed inside the mounting cavity.

[0014] As an improved technical solution, the detection body includes a fixed connecting plate installed on the inner wall of the arc-shaped drive bar. Two electric telescopic rods are installed on both sides of the fixed connecting plate near one end of the arc-shaped guide bar. A translation plate is fixed between the movable ends of the two electric telescopic rods. An ultrasonic probe is inserted and installed in the middle of the translation plate. An ultrasonic host is installed on one end of the translation plate near the fixed connecting plate.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the extension and retraction of the electric telescopic rod can adjust the height of the arc-shaped guide bar. The height of the arc-shaped guide bar can be adjusted according to the position of the pipe and the pipe of different sizes to make the arc-shaped guide bar and the pipe being measured coaxial, so as to ensure the normal operation of the testing equipment and adapt to different application scenarios.

[0017] 2. In this utility model, the electric telescopic rod II drives the translation plate to move, adjusting the distance between the ultrasonic probe and the pipe. The distance between the ultrasonic probe and the pipe can be adjusted, ensuring that the distance between the ultrasonic probe and the pipe is in the optimal state when testing pipes of different sizes, thereby ensuring the test results of the ultrasonic probe. Furthermore, the extension and retraction of the electric telescopic rod II can also make the ultrasonic probe fit snugly against the pipe for testing.

[0018] 3. In this utility model, both drive motors drive the mounting shaft to rotate. Under the meshing transmission of gears and arc-shaped racks, the arc-shaped drive bar rotates inside the sliding cavity. When the arc-shaped drive bar is driven to rotate 180 degrees, the far end of the arc-shaped drive bar will enter the interior of the arc-shaped guide bar and re-mesh with the nearest gear. At this time, the arc-shaped guide bar and the arc-shaped drive bar form a closed circle, and the arc-shaped drive bar can continue to be driven to rotate, so that the arc-shaped drive bar can rotate 360 ​​degrees around the pipe, performing a dead-angle inspection of the pipe and realizing efficient, accurate, and flexible ultrasonic testing of pipe materials.

[0030] like Figures 1 to 4 As shown in the figure, this embodiment provides an ultrasonic testing device for pipes. This ultrasonic testing device for pipes includes a housing 1 with an arc-shaped groove. An arc-shaped guide strip 2 is provided inside the arc-shaped groove of the housing 1. The arc-shaped guide strip 2 is semi-circular. A sliding cavity 22 is opened on the arc-shaped guide strip 2. An arc-shaped drive strip 4 is slidably installed on the arc-shaped guide strip 2 through the sliding cavity 22. The length of the arc-shaped drive strip 4 is greater than the length of the arc-shaped guide strip 2. A testing body 3 is fixed on the inner wall of the arc-shaped drive strip 4.

[0031] Both ends of the arc-shaped guide bar 2 are equipped with drive components 5 for driving the arc-shaped drive bar 4 to rotate. The drive components 5 include a gear 53 rotatably mounted on the end of the arc-shaped guide bar 2 and an arc-shaped rack 56 mounted on the arc-shaped drive bar 4. The gear 53 meshes with the arc-shaped rack 56. Both ends of the arc-shaped guide bar 2 have connecting grooves 21 on the outer side for the gear 53 to pass through.

[0032] like Figure 1As shown, in this embodiment, an electric telescopic rod 11 is fixed inside the housing 1, and the movable end of the electric telescopic rod 11 is located above the top of the housing 1. The movable end of the electric telescopic rod 11 is fixedly connected to a lifting frame 12, and one side of the lifting frame 12 is fixedly connected to the outer wall of the arc-shaped guide strip 2. The extension and retraction of the electric telescopic rod 11 can adjust the height of the arc-shaped guide strip 2. The height of the arc-shaped guide strip 2 can be adjusted according to the position of the pipe and the pipe of different sizes to make the arc-shaped guide strip 2 and the pipe being measured coaxial, so as to ensure the normal operation of the detection equipment and adapt to different application scenarios.

[0033] like Figures 3 to 4 As shown in the figure, in this embodiment, the drive assembly 5 also includes two shaft brackets 51 fixed to the ends of the arc-shaped guide strip 2, and a mounting shaft 52 is rotatably mounted between the two shaft brackets 51, and a gear 53 is sleeved on the mounting shaft 52.

[0034] like Figures 3 to 4 As shown in the figure, in this embodiment, a pad is fixed on the side of a shaft bracket 51 away from the arc-shaped guide strip 2, and a drive motor 54 for driving the mounting shaft 52 to rotate is fixed on the top of the pad, and the drive end of the drive motor 54 is connected to one end of the mounting shaft 52.

[0035] like Figures 3 to 4 As shown in the figure, in this embodiment, arc-shaped limiting cavities 41 are provided on both sides of the arc-shaped drive bar 4, and multiple limiting wheels 55 are rotatably installed on both sides of the inner wall of the arc-shaped guide bar 2 along the direction of the limiting cavity 41, and the rolling end of the limiting wheel 55 is located inside the limiting cavity 41.

[0036] like Figures 3 to 4 As shown in the figure, in this embodiment, the middle part of the outer wall of the arc-shaped drive bar 4 is provided with a mounting cavity 42 that communicates with the connecting groove 21, and the arc-shaped rack 56 is fixed inside the mounting cavity 42.

[0037] Both drive motors 54 drive the mounting shaft 52 to rotate. Under the meshing transmission of gear 53 and arc rack 56, the arc rack 56 is driven to move due to the fixed position of gear 53, which in turn drives the arc drive bar 4 to rotate inside the slide cavity 22. The rotation of the arc drive bar 4 will drive the detection body 3 to move. The ultrasonic probe 35 on the detection body 3 performs ultrasonic testing on the pipeline. When the arc drive bar 4 is driven to rotate 180 degrees, the far end of the arc drive bar 4 will enter the interior of the arc guide bar 2, and the 46 on it will re-mesh with the nearest gear 53. At this time, the arc guide bar 2 and the arc drive bar 4 form a closed circle, and the arc drive bar 4 can continue to be driven to rotate, so that the arc drive bar 4 can rotate 360 ​​degrees around the pipeline, performing a no-dead-angle test on the pipeline, realizing efficient, accurate and flexible ultrasonic testing of the pipe.

[0038] like Figure 2 As shown, in this embodiment, the detection body 3 includes a fixed connecting plate 31 installed on the inner wall of the arc-shaped drive bar 4. Electric telescopic rods 32 are installed on both sides of the fixed connecting plate 31 near one end of the arc-shaped guide bar 2, with the movable end of each electric telescopic rod 32 located away from the arc-shaped guide bar 2. A translation plate 33 is fixed between the movable ends of the two electric telescopic rods 32. An ultrasonic probe 35 is inserted into the middle of the translation plate 33. An ultrasonic host 34 is installed on one end of the translation plate 33 near the fixed connecting plate 31, and the ultrasonic host 34 and the ultrasonic probe 35 are connected by a wire. The extension and retraction of the electric telescopic rods 32 drives the translation plate 33 to move, adjusting the distance between the ultrasonic probe 35 and the pipe. The distance between the ultrasonic probe 35 and the pipe can be adjusted, ensuring that the distance between the ultrasonic probe 35 and the pipe is optimal when detecting pipes of different sizes, thus guaranteeing the detection results of the ultrasonic probe 35. Furthermore, the extension and retraction of the electric telescopic rods 32 also allows the ultrasonic probe 35 to be in close contact with the pipe for detection.

[0039] When in use, the pipe is inserted into the inner cavity of the arc-shaped guide bar 2. The extension and retraction of the electric telescopic rod 11 can adjust the height of the arc-shaped guide bar 2, so as to make the arc-shaped guide bar 2 and the pipe being measured coaxial.

[0040] The electric telescopic rod 32 drives the translation plate 33 to move, adjusting the distance between the ultrasonic probe 35 and the pipe to make the distance optimal.

[0041] After the distance between the ultrasonic probe 35 and the pipe is adjusted, both drive motors 54 drive the mounting shaft 52 to rotate. Under the meshing transmission of the gear 53 and the arc rack 56, the arc rack 56 is driven to move due to the fixed position of the gear 53, which in turn drives the arc drive bar 4 to rotate inside the sliding cavity 22. The rotation of the arc drive bar 4 will drive the detection body 3 to move, and the ultrasonic probe 35 on the detection body 3 will perform ultrasonic detection on the pipe.

[0042] When the arc-shaped drive bar 4 is driven to rotate 180 degrees, the far end of the arc-shaped drive bar 4 will enter the interior of the arc-shaped guide bar 2, and the 46 on it will re-mesh with the nearest gear 53, so that the arc-shaped drive bar 4 can continue to be driven to rotate, allowing the arc-shaped drive bar 4 to rotate 360 ​​degrees around the pipe.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
