The present invention relates to a moving platform of an inspection and maintenance device for a reactor head, comprising: an x-axis support unit (10) which is installed to be rotated on the upper top surface of a bioshield (201) installed in a reactor head (200) and move a z-axis support unit (40) installed on the top surface thereof forward/backward in an x-axis direction; a rotation axis support unit (20) which includes at least two or more axes, meets the x-axis support unit (10) at the center thereof and is extended to the upper top surface of the bioshield (201) in a radius direction; a rotation roller (30) which is attached to the ends of the x-axis support unit (10) and the rotation axis support unit (20) to be rotated along the upper top surface of the bioshield (201); the z-axis support unit (40) which is installed on the top surface of the x-axis support unit (10) to vertically move an inspection or maintenance device (300); and an x-axis actuator (50) which is installed on the other end of the x-axis support unit (10) to move the z-axis support unit (40) forward/backward along an x-axis. The moving platform is capable of: performing various works by freely detaching/attaching the non-destructive inspection and maintenance system in the reactor head; being applied to various reactor heads by freely adjusting lengths of the support axes: minimizing workers by automatically moving the inspection and maintenance system in a high radioactivity area; easily disassembling/assembling equipment; and minimizing workers by allowing the workers to freely move/install the equipment having the small weight, thereby improving efficiency in inspection and maintenance. |
