| 摘要 |
The present invention provides a device and a method for positioning components (3) of a scraper moved through laid pipelines along the inner pipeline wall, the components (3) being located on radially expandable support elements (2) in such a way that with the same spacing between the compo- nents and pipe wall for different pipe diameters there is a uniform coverage of the pipe circumference by the compo- nents (3). For this purpose in each case at least two sup- port elements (2) succeeding one another in the pipeline circumferential direction are pivotably interconnected by at least one connecting member (4) articulated thereto, so that the support elements (2) are equidistantly spaced in each expansion position.
