Description

Technical Field

[0001] This utility model relates to the field of clamp technology, and in particular to a clamp for acoustic detection of gas PE correction pipelines. Background Technology

[0002] Acoustic wave detection technology is based on the propagation characteristics of sound waves in materials. When sound waves encounter defects or interfaces in materials, they will be reflected, refracted, or scattered. In gas PE pipelines, the propagation speed of sound waves is related to the density, elasticity, and internal structure of the material. By receiving and analyzing these sound wave signals, the internal structure and defects of the pipeline can be inferred.

[0003] When performing regular ultrasonic testing on gas PE pipelines, the position and angle of the probe are inconsistent each time. Even if multiple tests are performed at the same position, the data obtained may vary significantly, making data analysis and comparison difficult and affecting the accuracy of the test results. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A clamp for calibrating a gas PE pipeline using acoustic wave detection includes a slide rail with symmetrically arranged protrusions on its surface. Several sets of sliding devices are slidably mounted above the protrusions. Each sliding device includes a fixed base and a first fixed plate. An ultrasonic detector body is fixedly mounted above the fixed base. A clamping device is fixedly mounted above the first fixed plate. The clamping device includes a fixed base, bearing seats, an optical axis, a slider, a support frame, a limiting plate, a second fixed plate, and an arc plate. The fixed base is fixedly mounted above the first fixed plate. The bearing seats are symmetrically fixedly mounted on both sides of the fixed base. The two ends of the optical axis are fixedly mounted between the bearing seats. The slider is symmetrically slidably mounted outside the optical axis. The support frame is symmetrically fixedly mounted in the middle of both sides of the fixed base. The limiting plate is fixedly mounted above the support frame. The second fixed plate is fixedly mounted above the slider. The arc plate is symmetrically mounted above the second fixed plate. A metal pipeline is clamped between the arc plates.

[0006] As an improvement to the above technical solution, the sliding device further includes a pulley, a support base, and a support column. The pulley is slidably mounted above the protruding strip, the support base is bolted to both sides of the pulley, and the first fixing plate is fixedly mounted between the fixing base and the support column.

[0007] As an improvement to the above technical solution, a support device is provided between the sliding devices. The support device includes a third fixed plate, a telescopic column, a telescopic rod, and a V-groove. The third fixed plate is fixedly installed on the upper surface of the protrusion, the telescopic column is fixedly installed at the four corners of the third fixed plate, the telescopic rod is fixedly installed in the middle of the third fixed plate, and the V-groove is fixedly installed on the upper part of the telescopic column and the telescopic rod.

[0008] As an improvement to the above technical solution, both the arc plate and the V-groove clamp the two sides of the metal pipe.

[0009] As an improvement to the above technical solution, the ultrasonic detector body is threadedly connected to the upper surface of the fixed base, and a detector detection end is provided at one end of the ultrasonic detector body, which is located below the metal pipe.

[0010] The beneficial effects of this utility model are:

[0011] 1. The slider of this utility model slides along the optical axis, driving the second fixed plate and the arc plate to move together to adapt to pipes of different diameters. The support frame enhances the stability of the clamping device, while the limiting plate restricts the movement range of the slider to prevent excessive movement from causing clamping failure or damage to the equipment. The sliding device drives the ultrasonic detector body to move along the metal pipe, which can comprehensively detect the internal condition of the metal pipe, promptly detect and deal with potential problems. The stability of the clamping device ensures the accuracy and safety of the detection process.

[0012] 2. This utility model ensures that the ultrasonic detector body and clamping device can maintain balance and accuracy during the detection process by having pulleys roll on the convex strips. The arc design of the arc plate can closely fit the circular cross-section of the pipe and provide uniform clamping force. The V-shaped structure of the V-groove also provides additional support points for the pipe, further enhancing the stability of clamping. The dual clamping mechanism ensures that the pipe will not move or shake due to external forces during the detection process. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] A clamp for calibrating gas PE pipelines using acoustic wave detection includes a slide rail 1. The surface of the slide rail 1 is symmetrically provided with raised strips 11. Several sets of sliding devices 2 are slidably mounted above the raised strips 11. Each sliding device 2 includes a fixed base 23 and a first fixed plate 25. An ultrasonic detector body 5 is fixedly mounted above the fixed base 23. A clamping device 3 is fixedly mounted above the first fixed plate 25. The clamping device 3 includes a fixed base 31, a bearing seat 32, an optical axis 33, a slider 34, a support frame 35, a limiting plate 36, a second fixed plate 37, and an arc plate 38. 31 is fixedly installed above the first fixed plate 25. The bearing seats 32 are symmetrically fixedly installed on both sides of the fixed base 31. The two ends of the optical axis 33 are fixedly installed between the bearing seats 32. The slider 34 is symmetrically slidably installed outside the optical axis 33. The support frame 35 is symmetrically fixedly installed in the middle of both sides of the fixed base 31. The limiting plate 36 is fixedly installed above the support frame 35. The second fixed plate 37 is fixedly installed above the slider 34. The arc plate 38 is symmetrically installed above the second fixed plate 37. A metal pipe 6 is clamped between the arc plates 38.

[0022] In this embodiment, the slide rail 1 provides a stable and linear sliding path for the entire fixture, ensuring that the ultrasonic detector body 5 and the clamping device 3 can move smoothly along a predetermined direction. The convex strip 11 on the surface of the slide rail 1 serves as a guide element for the sliding device 2, reducing lateral displacement during the sliding process and improving the accuracy of the detection. The fixed seat 23 of the sliding device 2 is mounted on the slide rail 1, providing a stable support platform for the ultrasonic detector body 5. The first fixed plate 25 connects the fixed seat 23 and the clamping device 3, ensuring that the clamping device 3 can move along the slide rail 1 with the sliding device 2. The ultrasonic detector body 5, fixedly mounted on the fixed seat 23, can perform continuous ultrasonic detection on the metal pipe 6 as the sliding device 2 moves, identifying defects, corrosion, or leaks inside the pipe. The fixed base 31 is fixedly mounted on the first fixed plate 25, ensuring the stability of the entire clamping device 3. The optical axis 33 supported by the bearing seat 32 provides a precise support for the slider 34. The precise sliding track allows the slider 34 to move smoothly along the optical axis 33 as needed, thereby adjusting the clamping width of the clamping device 3. The second fixing plate 37 is fixedly installed on the slider 34, providing a stable support platform for the arc plate 38. The arc plate 38 is symmetrically installed above the second fixing plate 37, and its arc design can closely fit the surface of the metal pipe 6, providing uniform clamping force and ensuring that the metal pipe 6 remains stable during the inspection process. The slider 34 slides along the optical axis 33, driving the second fixing plate 37 and the arc plate 38 to move together to adapt to pipes of different diameters. The support frame 35 enhances the stability of the clamping device 3, while the limiting plate 36 restricts the movement range of the slider 34 to prevent excessive movement from causing clamping failure or damaging the equipment. By driving the ultrasonic detector body 5 to move along the metal pipe 6 through the sliding device 2, the internal condition of the metal pipe 6 can be comprehensively inspected, and potential problems can be detected and dealt with in a timely manner. The stability of the clamping device 3 ensures the accuracy and safety of the inspection process.

[0023] Specifically, the sliding device 2 also includes a pulley 21, a support seat 22 and a support column 24. The pulley 21 is slidably mounted above the protrusion 11, the support seat 22 is bolted to both sides of the pulley 21, and the first fixing plate 25 is fixedly mounted between the fixing seat 23 and the support column 24.

[0024] In this embodiment, the protrusion 11 serves as a guide for the slide rail 1, providing a stable and low-friction sliding path for the pulley 21, reducing friction and making the sliding smoother. The support base 22 is bolted to both sides of the pulley 21, forming a stable support for the pulley 21 and preventing it from shifting or shaking due to lateral forces or vibrations. The support column 24 is connected between the fixed base 23 and the first fixed plate 25, playing a vertical support role, so that the sliding device 2 can maintain a stable posture when bearing the weight of the ultrasonic detector body 5 and the clamping device 3, avoiding bending or deformation. When the sliding device 2 moves on the slide rail 1, the pulley 21 rolls on the protrusion 11, ensuring that the ultrasonic detector body 5 and the clamping device 3 can maintain balance and accuracy during the detection process.

[0025] Specifically, a support device 4 is provided between the sliding devices 2. The support device 4 includes a third fixed plate 41, a telescopic column 42, a telescopic rod 43, and a V-groove 44. The third fixed plate 41 is fixedly installed on the upper surface of the protrusion 11, the telescopic column 42 is fixedly installed at the four corners of the third fixed plate 41, the telescopic rod 43 is fixedly installed in the middle of the third fixed plate 41, and the V-groove 44 is fixedly installed on the upper part of the telescopic column 42 and the telescopic rod 43.

[0026] In this embodiment, the third fixing plate 41 is fixedly installed on the upper surface of the protrusion 11, serving as the foundation of the support device 4 and providing a stable installation platform for supporting the telescopic column 42 and the telescopic rod 43. The telescopic column 42 is fixedly installed at the four corners of the third fixing plate 41, providing adjustable support height and stability. By adjusting the length of the telescopic column 42, the support device 4 can be adapted to different working environments and height requirements. The telescopic rod 43 is fixedly installed in the middle of the third fixing plate 41. Adjusting the height of the support device 4 ensures that the entire support device 4 is more balanced. The V-groove 44 is fixedly installed on the upper part of the telescopic column 42 and the telescopic rod 43, and the V-groove 44 also supports the metal pipe 6.

[0027] Specifically, the arc plate 38 and the V-groove 44 both clamp the two sides of the metal pipe 6.

[0028] In this embodiment, the arc design of the arc plate 38 can closely fit the circular cross-section of the pipe and provide uniform clamping force. The V-shaped structure of the V-groove 44 also provides additional support points for the pipe, further enhancing the stability of clamping. The dual clamping mechanism ensures that the pipe will not move or shake due to external forces during the inspection process.

[0029] Specifically, the ultrasonic detector body 5 is threadedly connected to the upper surface of the fixed base 23, and a detector detection end 51 is provided at one end of the ultrasonic detector body 5, which is located below the metal pipe 6.

[0030] In this embodiment, the ultrasonic detector body 5 is screwed onto the upper surface of the fixing base 23 through the thread at its bottom, thereby achieving a stable connection. The detector detection end 51 is located below the metal pipe 6. When the ultrasonic detector body 5 is installed on the fixing base 23 and fixed, its detection end will point towards and approach the bottom of the metal pipe 6 in order to perform ultrasonic detection on the metal pipe 6.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
