Abstract

The invention discloses a transfer mechanism used for large heavy-load components under the nuclear environment. Movement of a lifting hook is controlled by three hydraulic cylinders, and each hydraulic cylinder controls one direction. One hydraulic cylinder located on the lower side controls the freedom degree in the vertical direction and is connected with the lifting hook through a composite hinge and the like; the other hydraulic cylinder located on the lower side drives the stretching freedom degree and is connected to a universal joint on the rear portion of the lifting hook through theother set of composite hinge and the like; and the hydraulic cylinder located on the lateral upper side drives the lateral movement freedom degree and is connected with the side of the lifting hook through a spherical hinge. A reset spring is mounted at each of the top and the bottom of the mechanism. The transfer mechanism is used for the nuclear maintenance process, replacement of modules in large heat furnaces and the like.

Description

technical field [0001] The invention relates to the technical field of nuclear fusion reactor engineering, in particular to a transfer mechanism for large heavy-duty components in a nuclear environment. Background technique [0002] Nuclear fusion energy is a relatively clean new type of energy. It has the characteristics of less raw material consumption, abundant resources, and less radioactive pollution. Therefore, the research on controlled nuclear fusion has attracted more and more attention from all over the world. Tokamak magnetic confinement nuclear fusion is considered to be one of the most promising approaches in the commercialization of fusion energy. The Tokamak device includes an annular vacuum chamber for fusion reactions to occur. During the operation of the device, the divertor, the first wall part in the vacuum chamber, is subjected to plasma thermal shock and neutron radiation due to its long-term operation in a nuclear radiation environment. After a period...
