Radiotherapy device rotating machine frame support eccentric type adjustment device

Abstract

The present invention belongs to the technical field of radiotherapy devices and also discloses a radiotherapy device rotating machine frame support eccentric type adjustment device. The radiotherapydevice rotating machine frame support eccentric type adjustment device comprises a front end support device and a rear end support device, the front end support device and the rear end support deviceboth comprise a supporting base seat and a riding wheel support component, the riding wheel support component comprises a support box body and a riding wheel roller path component, the riding wheel roller path component comprises two sets of riding wheel support units, riding wheels in the front end support device are tapered riding wheels, the rear end support device uses cylindrical riding wheels, and riding wheel shafts are all eccentric shafts. The device has a certain self-alignment function, also can realize own axial limit, can perform fine adjustment in a vertical direction after initial installation, and thus reduces errors of rotation center vertical directions of the front and rear end support devices, so that the support devices have relatively high reliability and safety, andthe adjustment device is high in adjustment precision.

Description

technical field [0001] The invention belongs to the field of radiotherapy equipment, and more specifically relates to an eccentric adjustment device supported by a rotary frame of radiotherapy equipment Background technique [0002] In the field of radiotherapy equipment, large mass and large inertia are the difficulties that need to be considered in the design process. Especially in the process of on-site installation, due to the large mass, if the main part is installed on the support part, it is not easy to make adjustments, which will affect the coaxiality and positional accuracy of the overall equipment. Therefore, the precision adjustment in the installation process is very important. During the installation process, after the rotating frame is initially installed on the supporting device, it is necessary to fine-tune the rotating frame to ensure that its coaxiality error is within its accuracy range. If there is a certain deviation in the vertical direction of the c...

AI Technical Summary

Problems solved by technology

However, both the front and rear end support devices use tapered support rollers, which have relatively high requirements for axial limit, and there will still be great difficulty in positioning the initial installation of the rotating frame

[0004] Therefore, there are some problems in the support form of the prior art: 1) the difficulty of initial installation and debugging of the rotating frame during the installation process; The radius cannot be changed by axial movement, so that the front and rear ends support the fine-tuning of the error in the vertical direction
