APPARATUAS FOR CARRYING OUT REPAIR WORK ON A DAMAGED PIPE

摘要

The apparatus comprises a carriage (2) which carries on one face a working head (8) for a tool such as a milling tool (18). The working head is fully rotatable about the longitudinal axis of the carriage by means of a drive (10) acting on a gear (11) and is held in a bearing (9) and supported by a rotating shackle (12). The milling tool rests on a shaft (17); a mounting flange (19) makes it possible to use various types of tools, and in particular wheel-type tools. The shaft (17) is driven by a hydraulic motor (16). The working head (8) comprises a feed cylinder (13) wherein is located the hydraulic motor (16) just mentioned and the shaft (17) and which can be radially extended with regard to the pipeline (1). On the bearing (9) a holder (7) with a television camera is attached. The television camera only follows the rotational movements of the bearing (9) but not the radial displacements of the feed cylinder (13) and is therefore adjusted in such a way onto the tool (18) that it can cover the entire feed range of the tool.
