FIELD: machine building. ^ SUBSTANCE: invention refers to facilities for installation of blocks of linear accelerator on rail track with successive regulation of blocks position for adjustment of transportation track of ion radiation beam of accelerator. The support consists of a case, and of a travelling roller mounted on a guide; the roller is coupled with an axle by means of two preliminary strained rolling bearings; the axle rests on two cheeks of the support case. One end of the axle is threaded. Also one cheek has a thread, while another has a slot. The support is equipped with a differential threaded mechanism equipped with a leading link in form of a threaded hub screwed with internal thread with coarse pitch on a threaded end of the axle, while with its external thread with low pitch it is screwed into a threaded hole of the cheek. At the end of the axle opposite to the threaded one there is fixed a key interacting with the slot of the cheek; a lock bolt is inserted in the lugs of the key. The guide is made in form of the rail track; the profile of the rail is of trapezoid shape. ^ EFFECT: facility simple of design and process of fabrication, compact, and with accurate and simple adjustment of accelerator blocks. ^ 3 cl, 1 dwg |
