Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline detection, in particular to a multifunctional folding extension rod detection device. Background Art
[0002] The inspection of pipeline welds is used to check whether the quality of pipeline welds is qualified. There are two commonly used non-destructive testing methods, namely radiographic testing and ultrasonic testing. Non-destructive testing equipment is required in the process of pipeline weld inspection.
[0003] Existing nondestructive testing devices are unable to inspect welds in narrow inspection areas during use, which means that various defects may be missed. If extremely harmful defects such as cracks exist in undetectable areas, as the pipeline operates, the cracks may continue to expand under the influence of factors such as internal pressure, temperature changes, and medium corrosion, eventually leading to pipeline rupture and medium leakage. Therefore, we have launched a new multifunctional folding extension rod inspection device. Utility Model Content

[0029] In this embodiment, the adjustment mechanism 3 includes an adjustment seat 31 and a damping ball 32. A damping groove 33 is provided at the rear end of the adjustment seat 31. The left and right outer surfaces of the adjustment seat 31 are fixedly connected to a connecting frame 34. The rear end of the outer surface of the damping ball 32 is fixedly connected to a connecting rod 35. The damping ball 32 is partially embedded in the damping groove 33, and the outer surface of the damping ball 32 is movably connected to the inner wall of the damping groove 33. The ends of the two connecting frames 34 away from the adjustment seat 31 are fixedly connected to the folding rod body 2, and the rear end of the connecting rod 35 is fixedly connected to the connecting block 4.
[0030] Through the above scheme: by inserting the detection probe 6 into the slot 52 and locking it through the locking screw 54, the detection probe 6 can be easily and quickly installed on the folding rod body 2, so that the detection probe 6 can be easily and quickly installed and disassembled, reducing preparation time, and different pipeline flaw detection scenarios may require different types of detection probes 6. For example, when detecting thin-walled pipes, a high-frequency ultrasonic probe may be required to obtain more accurate internal defect information; for thick-walled pipes, a low-frequency probe may be required to enhance the penetration ability of ultrasonic waves. The detection probe 6 that is easy to install and disassemble allows the inspection personnel to quickly replace the appropriate detection probe 6 according to the specific conditions such as the material, wall thickness, weld type, etc. of the pipeline. This can ensure that the most optimized detection tool can be used for flaw detection work under different pipeline conditions, thereby improving the accuracy of detection.
[0031] In this embodiment, the mounting mechanism 5 includes a mounting ring 51, a through slot 52 is provided at the front end of the mounting ring 51, a fixing rod 53 is fixedly connected to the upper portion of the outer surface of the mounting ring 51, and a locking screw 54 is inserted and connected to the lower portion of the outer surface of the mounting ring 51. The mounting ring 51 is inserted and connected to the detection probe 6 through the slot 52, the upper end of the fixing rod 53 is fixedly connected to the connecting block 4, the end of the locking screw 54 passes through the mounting ring 51 and extends into the slot 52, and the end of the locking screw 54 is tightly fitted with the detection probe 6.
[0032] Through the above scheme: after the detection probe 6 is installed, the angle of the detection probe 6 can be easily adjusted by adjusting the activity of the damping ball 32 in the damping groove 33, and combined with the length adjustment of the folding rod body 2, it is convenient for the detection personnel to quickly move the detection probe 6 to the position of the pipeline that needs to be inspected, so that the detection probe 6 can accurately penetrate into these narrow spaces, avoiding pipeline rupture due to inadequate detection, and ensuring the continuity of the detection work. The entire detection device can be unfolded when in use and can be folded and stored after use, which has the advantages of being light and easy to carry.
[0033] It should be noted that the present invention is a multifunctional folding extension rod detection device. During use, by inserting the detection probe 6 into the slot 52 and using the locking screw 54 to implement fastening measures, the detection probe 6 is conveniently and quickly installed and removed from the folding rod body 2, which reduces the preparation time before detection. In view of the fact that different pipeline flaw detection tasks may require adaptation to specific types of detection probes 6, for example, when detecting thin-walled pipelines, a high-frequency ultrasonic probe may be required to obtain more accurate defect data; and for thick-walled pipelines, a low-frequency probe may be more preferred to enhance the penetration efficiency of ultrasonic waves. Therefore, the detection probe 6 that is easy to install and remove allows the detection personnel to adjust the defect according to the material, wall thickness, and welding thickness of the pipeline. The detection probe 6 can be quickly replaced with the most suitable detection probe 6 according to the specific conditions such as the type of seam, so as to ensure that the most optimized detection means can be adopted under various pipeline conditions, thereby improving the accuracy of detection. After the installation of the detection probe 6 is completed, the angle of the detection probe 6 can be conveniently adjusted with the help of the flexible adjustment of the damping ball 32 in the damping groove 33. At the same time, with the length adjustment function of the folding rod body 2, the detection personnel can quickly move the detection probe 6 to the position of the pipeline to be inspected, ensuring that the detection probe 6 can accurately penetrate into those narrow spaces, preventing pipeline damage caused by missed detection, and ensuring the continuity of the detection work. In addition, the entire detection device can be unfolded when in use and can be folded and stored after use. It is light and easy to carry.
