Zusammenfassung:	The utility model relates to a portal frame for flaw detection of a power transmission line. A guide part with a downward opening is arranged at the upper part of a fixed frame; the movable frame is in linear movement fit with the fixed frame, and the movable frame is used for mounting radiographic inspection equipment; the rotating frame is rotationally connected to the upper part of the movable frame, and the rotating frame is used for detachably mounting a receiving imaging bottom plate of the radiographic inspection equipment; the fixed frame and the movable frame which are formed by splicing the hollow rods are beneficial to light weight; the guide part with a downward opening is arranged on the fixed frame, so that the power transmission line can be guided to quickly and accurately move to the walking rollers on the fixed frame; and the receiving imaging bottom plate is detachably mounted on the rotating frame, so that the receiving imaging bottom plate can be conveniently maintained in the later period
