[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be conveyed by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations.

[0003] After production, pipelines need to be inspected, and equipment is used to detect whether there are damages and cracks on the outside. However, commonly used inspection equipment needs to be moved to different positions of the pipeline for inspection. The use of manual equipment for inspection consumes more physical energy and is more difficult, resulting in poor pipeline production efficiency and failure to meet practical needs. Therefore, a pipeline defect detection device is proposed to solve the above problems. Utility Model Content

Then the first motor 3 is started to drive the transmission gear 4 to rotate, and at the same time drives the driven gear 5 and the rotating rod 6 to rotate, thereby driving the clamping assembly to rotate, so as to facilitate the detection of the detection equipment body 15 and effectively improve the detection efficiency of the pipeline.

[0025] In this embodiment, the telescopic mechanism includes a second motor 12 arranged on the upper surface of the base 1, and an adjusting screw 13 is fixedly installed on the output shaft of the second motor 12. The rotating connecting piece at the end of the adjusting screw 13 away from the second motor 12 has a bearing, and the bearing is fixed to the right outer wall of the left column 2.

[0026] It should be noted that there are two telescopic mechanisms and two detection device bodies 15, which are located at the upper and lower sides of the pipeline, and the threads on the two adjusting screws 13 are opposite, so the two detection device bodies 15 move back and forth in relative directions. The detection device body 15 is a conventional device known to the public in the prior art, so its specific structure and working principle will not be described in detail in this article.

[0027] When this embodiment is in use, the second motor 12 is started to drive the adjusting screw 13 to rotate, and at the same time drive the adjusting sleeve 14 to move, thereby driving the detection device body 15 to move.

When in use, the telescopic cylinder 7 is started to drive the placement table 8 to move, and then the pipeline is placed on the placement table 8. The screw 10 is rotated to drive the clamp 11 to move, so that the clamp 11 clamps the pipeline. Through the clamping of the clamp 11, the pipeline can always remain stable when rotating.

[0030] In this embodiment, the adjusting screw 13 is movably connected to the column 2, and a limit assembly 17 is provided on the outside of the column 2. The side of the adjusting sleeve 14 away from the detection equipment body 15 is connected to the limit assembly 17, and the limit assembly 17 includes a limit rod fixedly installed on the opposite sides of the two columns 2, and the outside of the limit rod is slidably connected to the limit sleeve, and the side of the limit sleeve close to the adjusting sleeve 14 is fixedly installed on the connecting block connected to the adjusting sleeve 14. When in use, the limit sleeve is limited by the limit rod, so that the adjusting sleeve 14 can always remain stable when it is displaced, thereby achieving the advantage of stability. There are two limit assemblies 17, and the end of the left telescopic cylinder 7 away from the placing table 8 is fixed to the end of the rotating rod 6 away from the driven gear 5, and the right telescopic cylinder 7 is rotatably connected to the outer wall of the right column 2, and the right telescopic cylinder 7 is rotatably connected to the right column 2 through a bearing, and the bearing is a third bearing.

Through the clamping of the clamp 11, the pipeline can always remain stable when rotating, and then starts the first motor 3 to drive the transmission gear 4 to rotate, and drives the driven gear 5 and the rotating rod 6 to rotate, thereby driving the clamping assembly to rotate, and then starts the second motor 12 to drive the adjusting screw 13 to rotate, and drives the adjusting sleeve 14 to move, thereby driving the detection device body 15 to move. At this time, the two detection device bodies 15 move back and forth in relative directions to detect the pipeline, thereby achieving the effect of facilitating detection and effectively improving detection efficiency.
