A flexible adaptive large length to thin ratio pipeline intelligent repair device is provided. The walking mechanism includes a walking bracket and a radius adjustment assembly. The radius adjustment assembly is located in the middle of the walking bracket. The first motor for driving the radius adjustment assembly is set in the middle of the walking mechanism, and the second motor for driving the movement of the walking bracket is set on the walking bracket. The ends of several groups of connecting rods are removably connected to the working part, which includes the pre-welding sandblasting mechanism, the heating mechanism and the welding repair mechanism. A positioning sensor is set on the walking bracket. The variable-diameter all-position intelligent pipe internal repair device can integrate pre-welding cleaning, preheating, welding repair and post-welding heat treatment.
