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.

Disclosed is a beam energy dispersion adjusting mechanism for superconducting proton cyclotron. The adjusting mechanism includes a vacuum cavity, bases are symmetrically mounted on outer walls of four faces of the vacuum cavity in horizontal and vertical directions, an electric cylinder and a transmission mechanism are mounted on each of the four bases, a jaws block and a position fixing plate are correspondingly provided on an inner wall of the vacuum cavity at each face. The transmission mechanism includes an oil-free sleeve, a moving connecting rod onto which the position fixing plate is fixed, a corrugated pipe, and an electric cylinder connecting block whose both ends are screwed with the moving connecting rod and the electric cylinder, the jaws block is fixedly connected with the position fixing plate. The disclosure utilizes the electric cylinder to drive the jaws block to complete specified linear displacement, and satisfies back-end beam quality requirements.
