Abstract

The invention belongs to the technical field of nuclear power station reactor maintenance, and particularly relates to a centering guide system of a nuclear power station reactor protection tube assembly transportation platform, which improves the structural strength and deformation resistance of a lifting wrench. The diameter of the handle is increased, and the non-deformability is improved; the rotating radius of the handle is properly reduced, and extrusion and collision between the handle and the measuring tube of the neutron temperature measuring channel in the operation process are avoided.

Description

technical field [0001] The application belongs to the technical field of nuclear power plant reactor maintenance, and in particular relates to a centering guide system for a transport platform of nuclear power plant reactor protection tube components. Background technique [0002] Nuclear power plant reactor, including: reactor pressure vessel, core basket, core coaming, protection tube assembly, fuel assembly, control rod assembly, upper assembly, protective steel structure, control rod drive mechanism and other components. In order to maintain the normal operation of the reactor and provide continuous energy for the turbogenerator set, it is necessary to regularly replenish new fuel assemblies to the reactor and remove spent fuel assemblies. [0003] In order to achieve this goal and ensure that all other auxiliary equipment of the nuclear power plant can operate normally, the nuclear power unit needs to carry out regular preventive overhaul work. In the preventive overha...
