Abstract
An insertion device for a cable in an existing pipe network includes a longitudinally stable flexible element that can be inserted into a pipe region of the pipe network, and on which a head part can be placed. The head part can be diverted to pass through regions of bends of the pipe. Placed on the flexible element is a coupling part to which coupling part the cable to be pulled can be coupled. The head part includes a base body having an elongated shape, which can be led from a stretched position into a bent position. The base body includes guide elements by which at least one pulling element is guided that is spaced apart from the bending axis of the base body. One end of the pulling element is held at one end region of the base body, whereas the other end is held at a drivable linear drive that is attached at the other end region of the base body. Disposed at the end region, remote from the flexible element, of the head part are a light source and a camera. With this device, bends, elbows, and branches in an existing pipe network can be passed through in the desired direction without a problem.
