The invention discloses a large-diameter seamless pipe end online flaw detection device which comprises a plurality of rotating riding wheel mechanisms, two lifting pressing wheel mechanisms, two pipe end flaw detection mechanisms, two plug pieces and a control terminal. The multiple rotating riding wheel mechanisms are sequentially arranged in the transverse direction and used for jointly supporting the non-end portion of the same large-diameter seamless pipe and jointly driving the same large-diameter seamless pipe to rotate around the transverse axis of the rotating riding wheel mechanisms. The two pipe end flaw detection mechanisms are respectively provided with two coupling flaw detection ends for performing ultrasonic flaw detection after being coupled with the lower ends of the two ends of the same large-diameter seamless pipe, and each pipe end flaw detection mechanism comprises a transverse driving part for driving the corresponding coupling flaw detection end to move in the transverse direction and a vertical driving part for driving the corresponding coupling flaw detection end to move in the vertical direction. According to the invention, the whole end part of the large-diameter seamless tube can be subjected to ultrasonic flaw detection, and the coupling flaw detection end can still keep stable medium coupling at the tail end of the large-diameter seamless tube, so that the length of a flaw detection blind area is reduced to be absolutely zero, and manual detection is completely avoided.
