A positioning mechanism for a pipeline flaw detection device

Abstract

The utility model relates to pipeline flaw detection detection device uses positioning mechanism technical field, specifically for a kind of pipeline flaw detection detection device uses positioning mechanism, including: detection ring, the inside four around of detection ring is equipped with multiple groups first telescopic slot, elastic telescopic block in first telescopic slot, the outside end of telescopic block is provided with gyro wheel, one side surface of gyro wheel is equipped with multiple groups limit hole, the detection ring is equipped with corresponding through-hole in the side of telescopic block limit hole, through-hole is parallel with limit hole, through-hole is equipped in the top of first telescopic slot, the detection ring is equipped with second telescopic slot in the both sides of through-hole, elastic telescopic column is connected in second telescopic slot, the outside of telescopic column is connected with telescopic ring;Beneficial effect is: the utility model proposes a kind of pipeline flaw detection detection device uses positioning mechanism, when detecting pipeline, first according to the height of pipeline placement, start air cylinder drive telescopic rod drive detection ring to lift, make the center of detection ring with the center of pipeline parallel.
