Abstract (en)
[origin: ES8206251A1] Manipulator for positioning a tube probe at tube mouths of heat-exchanger tubes by remote-control of the tube probe which is connected to a flexible supply line for inspecting and/or repairing the heat-exchanger tubes, the tube mouths being disposed in a tube sheet and extending over an approximately semicircular tube field defined by a chord, includes at least three clamping devices distributed over the length of a carrying body fixed to the tube sheet and being lockable independently of one another in respective tube mouths of the tube sheet, the clamping devices being formed as insertable and retractable expanding mandrels extending from the carrying body towards and spacing the carrying body from the tube sheet, a boom having a swivel head by which it is fastened to a rotary shaft of a swing drive seated on the bearing surface of a support facing towards the tube sheet, a mouthpiece disposed at a free end of the boom and spaced from the rotary shaft a distance greater than a perpendicular distance of the rotary shaft from the chord defining the approximately semicircular tube field, the mouthpiece being thereby pivotable with the boom into the space between the carrying body and the tube sheet for introducing the tube probe into the respective tube mouths located thereat.
