SMALL MOBILE FEEDER PIPE INSPECTION ROBOT FOR PRESSURIZED HEAVY WATER REACTOR WITH ONE-TOUCH INSTALLATION MECHANISM

摘要

The present invention relates to a mobile robot for inspecting the water supply pipe for pressurized heavy water reactors, the purpose of which is to automatically move along the water supply pipe attached to the pressure pipe of the heavy water reactor reactor, while measuring the thickness of the water supply pipe, In addition, it is possible to measure up to the secondary curved pipe part to improve the safety of the reactor, and the installation of the device provides a mobile robot for inspecting the water supply pipe that can reduce the exposure of the worker because the measurement is performed simply and automatically by the one-touch method. Is in.;The present invention provides a rear gripper portion attached to the outer wall of the water supply pipe, a rotation driving unit attached to the rear gripper unit to provide a rotational driving force to rotate in the circumferential direction, and attached to the rotary driving unit to move forward and backward in the longitudinal direction of the water supply pipe. The technical gist of the present invention relates to a one-touch inserting pressurized heavy water reactor for a feedwater pipe inspection mobile robot comprising an expansion driving unit for providing a driving force and a front gripper unit attached to the expansion driving unit and freely rotating.
