Apparatus for inspecting and repairing tubes of a nuclear power plant

摘要

By providing a yoke (36) to the shoulder (15) of a robot for in­specting and repairing the tubes of a nuclear boiler, which yoke can receive an expandable anchoring piece (35) of an auxiliary tool (23) connected to the wrist (18) of the robot, said auxiliary tool (23) being provided with additional span fingers (37, 38), it is no longer a time-consuming and therefore expensive procedure to also inspect the tubes that lead to the tube sheet passages (9) into which the usual span fingers (8) of the robot were originally fixed.
