Frame structure for medical electronic linear accelerator, and medical electronic linear accelerator

The utility model provides a frame structure for a medical electronic linear accelerator, and the medical electronic linear accelerator. The frame structure comprises axial positioning wheel packs that are fixedly disposed on a base and comprise a front positioning wheel pack and a back positioning wheel pack. The front positioning wheel pack and the back positioning wheel pack are respectively tangential to two side surfaces of a back roller ring of the frame. The frame structure further comprises roller support wheel packs that is fixedly disposed on the base and comprises a front support wheel pack and a back support wheel pack. The front support wheel pack is tangential to the outer circular surface of the front roller ring of the frame, and the back support wheel pack is tangential to the outer circular surface of the back roller ring of the frame. A power conveying device drives the frame to rotate in the circumferential direction, so that the roller support wheel packs rotate along with the frame. The medical electronic linear accelerator achieves an integrated structural design of a medical accelerator, and utilizes multi-point roller support positioning manner to achieve reliable circumferential positioning. The medical electronic linear accelerator is simple in structure and convenient in debugging and maintenance.
