Abstract

The invention discloses an anti-collision device of a sickle-typed digital radiography system, which comprises a lifting motor and a rotating machine, and also comprises an altimeter coder, an angle encoder, a control module, a lifting motor driving module, and a rotating machine driving module. The altimeter coder and the angle encoder are respectively connected with the control module; the control module is connected with the lifting motor driving module and the rotating machine driving module; the lifting motor driving module is connected with the lifting motor; the rotating machine driving module is connected with the rotating machine; the altimeter coder is connected with the lifting motor through a gear; the angle encoder is connected with the rotating machine through the gear.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a sickle-shaped anti-collision device for a digital radiography system. Background technique [0002] The sickle-shaped digital radiography system consists of the following parts: ball tube, sickle-shaped frame, high-voltage generator, imaging work collection station, imaging bed, DR (Digital Radiography, digital radiography) detector, and control box. Sickle racks get their name from the sickle-like shape of their arms. The ball tube and DR detector are respectively installed at both ends of the sickle arm of the sickle frame. The distance between the tube and the DR detector can be adjusted from 1 meter to 1.8 meters according to the photographed body parts. The sickle arm can move vertically on the frame by 40cm to 200cm up and down according to the needs of the photographed part of the patient. At the same time, it can also rotate from -30° to 120°. To meet the ...
