摘要

The invention relates to an auxiliary device (100) for repairing a pipeline and sealing small damages (5) in a wall (4) of a pipeline. A working room (8) can be created between the interior of the pipeline (3) and the outer circumference of the base element (22) when the auxiliary device (100) for repairing a pipeline is pushed into a pipeline. The working room (8) can be sealed in the axial direction of the pipeline (3) and in a jointing manner by means of the expanding sealing collars (24, 25). Said auxiliary device (100) is provided with a transport module (40) that is articulated to the sealing module (20). The device can be transported through the fluid flow by means of the transport module (40).
