Abstract

The invention relates to a rack structure of a medical electronic linear accelerator. The rack structure comprises a main board, side boards fixed on two sides of the main board, a connecting frame upper connecting board fixed above the main board as well as connecting frame lower connecting boards fixed below the main board, wherein the main board comprises an upper main board and a lower main board, the upper main board is connected with a spindle, a middle partition board is fixed in the middle of the spindle, and the middle partition board is fixedly connected with the side boards through a front baffle. The connected rack forms a closed cavity or a closed ring, a long inner cavity is divided into two sections, and the rigid deformation during load bearing is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of accelerators, in particular to a frame structure of a medical electron linear accelerator. Background technique [0002] The frame is an important frame structure of the entire medical linear accelerator. All components, counterweights, accelerating tubes, modulators, etc. must be installed on the entire frame, so the entire frame is an important part. The entire frame including the rotating frame and the fixed frame must not only ensure the mechanical properties and welding properties of the material, but also revolve around the same center point, the mechanical isocenter, when the frame rotates 360°, so the mechanical isocenter of the frame is The accelerator is used as the only reference point for locating the patient's tumor position when radiotherapy equipment is used for radiotherapy. Therefore, it is necessary to ensure that the 360° fixed-point treatment of the fixed-point position is realized und...
