Abstract
A honeycomb rib structure in a rotating gantry of a proton includes an upper honeycombed rib plate and a lower honeycombed rib plate which are mounted in a cylindrical body through a plurality of connecting structures. The upper and lower honeycombed rib plates are symmetrically arranged, and are spliced by a plurality of basic structures which are in a regular hexagonal shape. Connecting nodes between the adjacent basic structures are of a ring structure. Densities of the upper and lower honeycombed rib plates are adjusted through a density increasing structure.
