Grabbing device for fast reactor assembly transfer process

Abstract

The invention belongs to the technical field of mechanical grabbing, and particularly relates to a grabbing device for the fast reactor assembly transfer process. The grabbing device comprises an outer sleeve and a self-locking assembly; a cavity is formed in the outer sleeve, one end of the outer sleeve is of an open structure and communicates with the cavity, and the other end of the outer sleeve is of a closed structure; two first through holes are formed in the side wall of the end, close to the open structure, of the outer sleeve, and the two sets of first through holes are symmetrically arranged with the central axis of the cavity as the symmetry axis; and the self-locking assembly comprises a pull rope, clamping jaws and a tension spring. The grabbing device solves the problem that the grabbing space of a fast reactor assembly is small; the synchronous action design mode of the clamping jaws guarantees the operation safety; and the grabbing device is suitable for the grabbing working condition of small-batch assemblies, and compared with a full-automatic grabbing device, the grabbing device is ingenious in structure, low in manufacturing cost, high in economic benefit and low in failure rate and maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of mechanical grabbing, in particular to a grabbing device used in the transfer process of fast reactor components. Background technique [0002] With the development and construction of the nuclear industry, the development and research of related products has gradually expanded. For the nuclear industry, the safety of the development and production process is very important. Among them, the safety operation requirements for the transfer and grabbing of core components are also getting higher and higher. [0003] During the component test process before the finalization of the fast reactor components, when the components are grasped and transferred, due to the small operating space, the operation is difficult, which affects production safety. And due to the component test operation before the fast reactor component is finalized, it belongs to the small batch use condition. At present, there is no grabbin...
