Abstract

The invention provides a replacing tool for control rod associated components of a nuclear power plant. The replacing tool comprises a support frame, a lifting structure, a gripper structure, a locking structure, a guide structure, a position detecting part and a digital position display screen, wherein the gripper structure comprises a spindle and a gripper assembly arranged at the bottom of thespindle, and the gripper assembly is used for gripping to-be-replaced pieces; the locking structure is used for controlling the gripper assembly to clamp or loosen the to-be-replaced pieces; the guidestructure is used for guiding lifting motion of the to-be-replaced pieces; the position detecting part is used for detecting positions of the to-be-replaced pieces; the digital position display screen is electrically connected with the position detection part and used for displaying height of the to-be-replaced pieces. Reliable replacement of the to-be-replaced pieces such as the control rod associated components is realized through cooperation of the lifting structure, the gripper structure, the locking structure, the guide structure, the position detecting part and the digital position display screen, safety of the to-be-replaced pieces such as the control rod associated components in the replacement process is ensured, safety is improved, and requirements for operation of the associated components in the daily and overhaul work of nuclear power are met.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment, in particular to a replacement tool for components related to control rods of a nuclear power plant. Background technique [0002] The daily work of the nuclear power plant needs to displace the related components of the control rods that are inserted into the fuel assemblies to meet the requirements of spent fuel transportation; grasp the related components of the control rods for ultrasonic eddy current inspection; In each cycle, the control rods on the fuel assemblies in the stack must be displaced to meet the requirement that the position of the control rods remain unchanged in the core. Therefore, the R&D and application of control rod-related component replacement tools for nuclear power plant control rod-related components play a very important role in the smooth progress of daily and overhaul work in nuclear power plants. [0003] At present, the switching tools for control...
