INTAKE DEVICE FOR A CABLE IN AN EXISTING PIPE NETWORK

Document Type and Number:

WIPO Patent Application WO/2010/063738

Kind Code:

A3

Abstract:

An intake device for a cable in an existing pipe network comprises a longitudinally stabile bending element (2) that can be pushed into a pipe area of the pipe network, with a head section (1) able to be placed on said bending element. In order to pass through bend areas of the pipe, the head section (1) can be diverted, and a coupling section (3) is placed on the bending element (2), the cable to be pulled in being couplable to the coupling section. The head section (1) comprises a base member (4) having an elongated shape, said base member capable of being diverted from a straight position to a bent position. The base member (4) is equipped with guide elements (15) for guiding at least one pulling element (14) that is at a distance from the bending axis of the base member (4). An end of the pulling element (14) is held at one end area of the base member (4), whereas the other end is held at a driveable linear drive (13) that is fastened at the other end area of the base member (4). Disposed at the end area of the head section (1) facing away from the bending element (2) are a light source (17) and a camera (18). With this device, deflections and branchings in the desired direction in an existing pipe network can be passed through without a problem.
