Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] as attached figure 1 , 2 As shown in and 5, the present invention provides a track base for a medical accelerator treatment bed, the track base includes a circular base 1 and a base body 2.

[0020] Wherein, the circular base is a ring-shaped steel base, which is pre-buried in a pre-set pit through tooling positioning. The bottom surface of the pit needs to be basically level, and the depth is consistent with the height of the circular base, so that the center line of the installed circular base basically coincides with the vertical line passing through the isocenter of the accelerator. After the circular base 1 is installed, the pit space around the base is filled with concrete 10. The bottom surface of the circular base 1 is provided with a circular groove 8 matching the mounting surface 9 at the bottom of the base body 2. The center point of th...

Abstract

The invention discloses a track pedestal for a medical accelerator treatment bed, and belongs to the technical field of structural design of accelerator medical equipment. The track pedestal comprisesa circular base and a pedestal body; the circular base is fixed inside the foundation of the ground, the pedestal body cooperates with a positioning surface on the circular base for primary positioning, a center positioning hole and a circular track are internally processed in the pedestal body, the center positioning hole serves as a centering hole for the rotation of the treatment bed and has the functions of positioning the center of the bed body of the treatment bed and limiting the vertical direction, and the circular track is located at the edge of the pedestal body and provides supportfor a treatment bed pedestal; the pedestal body achieves the adjustment of the levelness of the circular track and the fixation of the circular base through a plurality of sets of adjustment holes. The track pedestal has the advantages of being simple in structure, high in rigidity, good in flatness of the track, high in installation precision, convenient to adjust, large in circular track diameter and the like, and can be applied to simulated positioner diagnostic beds or other machine tools and equipment with the rotary function.

Description

technical field [0001] The invention relates to a track base, in particular to a track base structure design of a medical accelerator treatment bed, and belongs to the technical field of accelerator medical equipment structure design. Background technique [0002] The accelerator treatment bed is the key equipment for assisting tumor radiation therapy, and its multi-degree-of-freedom motion positioning accuracy and structural rigidity directly affect the effect of radiation therapy. Rotation about the axis of the vertical line passing through the isocenter of the accelerator is one of the degrees of freedom of motion that the treatment couch must have. At present, the rotation is mainly realized by the slewing bearing, which is difficult to locate and adjust, and has high requirements for the construction of the foundation. In order to ensure the structural rigidity of the base, the structure is heavy and complicated. Contents of the invention [0003] In view of this, t...
