FIELD: medical equipment. ^ SUBSTANCE: mobile compact X-ray apparatus includes x-ray supplying device, stand having mobile base and including post with device for lifting positioner with irradiator supplied with electric drive, upper part of which incorporates hingedly fixed positioner consisting of device for changing positioner inclination with holder and balancing system and device for turning irradiator jaw with fixation. Irradiator includes device for lightening with automatic switching-off of bulb, laser distance meter and device of irradiation diafragming. In device for lifting positioner with irradiator linear drive of converting rotation of drive shaft into translational movement of attached carriage is made from two cases capable of clamping to each other by means of four force springs with two pairs of bearing units, which are located symmetrically so that to form screw mechanical trajectories with similar angle of raising of rotating external bearing rings on surface of smooth drive shaft. Device for changing positioner inclination with holder and system of balancing consists of support for fixing positioner with lifting device, positioner profile being fixed with axis located in support walls, pneumatic cylinder fixed by means of hinged connection of mobile rod with support walls, and by means of hinged case connection, with bearing profile of positioner. Mobile rod is located in guides of bar, which is fixed with one end through hinged connection, to mobile rod, and with the other end to axis fixed in walls of support and locking device fixed on positioner profile and consisting of holder, crimping mobile rod and position locker with handle. ^ EFFECT: better X-ray apparatus stability during operation and transportation. ^ 5 cl, 6 dwg |
