Specific embodiments

[0024] like Figures 1 to 5 As shown, a pipeline flaw detection device includes a clamping portion 1 for clamping a pipeline and a flaw detection portion 2 rotatably connected to the clamping portion 1;

[0025] The clamping part 1 includes a clamping seat 11 and a plurality of clamping members 12 sliding on the clamping seat 11 and an active frame 13 driving the clamping members 12 to slide. The active frame 13 is fixedly connected to a driving element 14. A plurality of driven frames 15 are also provided between the clamping members 12 away from the active frame 13. Specifically, the clamping member 12 includes a first slider 121 and a roller 122 provided at the front end of the first slider 121. The roller is rotatably connected to the first slider 121. After the roller clamps the pipeline, the flaw detection part 2 is rotated first. After the inspection is completed, the roller can be used to move along the pipeline to avoid re-clamping and save time. Specifically, the active frame 13 is provided with two groups of first inclined rods 131. The first inclined rods 131 are slidably connected to the first slider 121. Each group of first inclined rods 131 is perpendicular to the direction of movement of the connected first slider 121. Specifically, the driven frame 15 includes a second slider 151 and a driven rod 152 slidably connected to the second slider 151. The driven rod 152 is provided with two groups of second oblique rods 152-1. The two groups of second oblique rods 152-1 are respectively slidably connected to the two adjacent groups of first sliders 121. Each group of second oblique rods 152-1 is perpendicular to the direction of movement of the connected first slider 121.

[0026] The flaw detection unit 2 includes a flaw detection base 21, a set of flaw detection parts 22 that slide on the flaw detection base 21, and a flaw detector 23 fixed to the flaw detection parts 22. The flaw detection parts 22 are provided with a limiter 24 for limiting the position of the flaw detection parts 22. Specifically, a signal transmitter 25 is also fixedly connected to the flaw detection base 21. The signal transmitter 25 is connected to the flaw detector 23 by an electrical wire. The signal transmitter 25 is used to transmit the information collected by the flaw detector 23 to a terminal. During use, the flaw detector transmits data to the terminal, and the operator can observe the data through the terminal. Specifically, the contact surface between the flaw detection base 21 and the clamping base 11 is provided with a raised guide rail 26. The clamping base 11 is provided with a groove to accommodate the guide rail 26. The guide rail 26 is magnetic, and the flaw detection base 21 rotates with the clamping base 11 via the guide rail 26. After the flaw detection part and the clamping part are put on the pipe, the flaw detection part and the clamping part are adsorbed through the guide rail. When flaw detection is performed, the flaw detection part can also be rotated.
