Abstract
An apparatus for supporting and moving tools for fixing a cluster of tubes to the tubular plate (2) of a steam generator, comprising a first running track (25), a carriage (26) movable on this track, a horizontally alignable support (39) resting on the carriage 26, a second running track (43) carried by the support (39) and perpendicular to the track (25), and at least one supporting structure (42) consisting of a base (45) movable on the second running track (43) and carrying a vertical column (46), a tool holder (54) being mounted to move on the column (46) to offer a tool opposite each of the holes in the plate (2) in succession by virtue of a motor driven guiding and displacing elements (53-55) carried by the column (46) and of elements (31, 50,51) for moving the carriage (26) and the structure (42). The invention applies particularly to assembling the steam generator of pressurized-water nuclear reactors.
