Nuclear power plant fuel loading and unloading tool and loading and unloading process

Abstract

The invention belongs to the technical field of fuel loading and unloading tools, and particularly relates to a nuclear power plant fuel loading and unloading tool and a loading and unloading process. The nuclear power plant fuel loading and unloading tool comprises a driving mechanism and a push rod mechanism detachably connected to the driving mechanism, wherein a workbench is arranged below the driving mechanism and the push rod mechanism, a rotating disc is rotationally connected to the top of the workbench, and a rotating groove is formed in the top of the workbench. During work, a screw used for fixing the driving mechanism is taken down, then a rotating plate is rotated downwards, the driving mechanism can be turned over, different surfaces of the driving mechanism are overhauled, the driving mechanism can be driven by the mounting frame to rotate by rotating the rotating disc, the surface to be overhauled is moved to the front of a worker, the worker can stand in situ to overhaul different surfaces of the driving mechanism, operation steps are reduced, the driving mechanism does not need to be turned over repeatedly during working, manpower is saved, the labor intensity of the worker is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fuel loading and unloading tools, and in particular relates to a nuclear power plant fuel loading and unloading tool and a loading and unloading process. Background technique [0002] Nuclear power plant fuel is nuclear fuel, which refers to the material that can generate practical nuclear energy through nuclear fission or nuclear fusion in a nuclear reactor. During the working process of a nuclear power plant, it is necessary to continuously load and unload fuel. At present, heavy water reactor loading and unloading machines are generally used to carry out fuel When the reactor is running, two heavy water reactor loading and unloading machines are connected to the two ends of the fuel channel to cooperate with each other to complete non-stop refueling. [0003] In the current heavy water reactor loading and unloading machine, the tape drive mechanism and push rod assembly are combined to complete the fue...

AI Technical Summary

Problems solved by technology

[0003] In the current heavy water reactor loading and unloading machine, the tape drive mechanism and the push rod assembly are combined to complete the fuel loading and unloading work. The tape drive mechanism is one of the important equipment on the loading and unloading machine, so the maintenance of the tape drive mechanism is very important. It is cumbersome, and it needs to be turned over many times for maintenance, and workers need to change their standing positions to check and repair different positions, which increases the labor intensity of workers and reduces work efficiency
