Remotely operated head inspection system

The present invention is a nozzle of the tube clearance is installed on the reactor head to scan in a non-destructive method such as a nuclear power plant within the high radiation zones in the eddy current inspection area with a remote control in order to evaluate the soundness of the reactor head and a tube customs inspection and ultrasonic testing and It relates to an inspection system for weld pipe clearance, By mounting the reactor head bolt holes formed in the outer periphery in a dedicated stand, in the inspection system for non-destructive testing of the nozzle and the tube clearance welding location of the nozzle, the tube clearance without a sleeve of a sleeve provided in the reactor head built-tube clearance , A track made of a structure that is placed in the dedicated stand, separate assembly of the at least two bodies; Is installed on one side of the right and left of the track, the wing that grooves are formed; Are inserted on both sides of the body portion is a bolt hole and the threaded groove of the wing, is formed formed in the reactor head, respectively through the fixed shaft by a fixing member provided on the two side portions for fixing the track to the reactor head; Leveling member which is installed at the other side the right and left of the track, a part of the body conveying the reciprocating up and down by a motor to match the level of the track; Trolley is possibly installed to the transfer track; Transfer means for transferring the trolley; It mounted to the trolley, having a plurality of axes, down, before, after, left or right to move the known articulated robot; Is mounted to the articulated robot, the checking means for non-destructive testing of the nozzle and the tube clearance weld the tube clearance; And the leveling member, a transfer means, and controller for operating the articulated robot and the inspection means; consists of. Reactors, tube clearance, the articulated robot, the scan head, track leveling member, welding
