EQUIPMENT POSITIONING DEVICE Russian patent published in 2006 - IPC B66F19/00 B66F11/00 B66F3/08 F16M13/00 

FIELD: general engineering; positioning devices.

SUBSTANCE: proposed device contains pack of three plates on adjacent surfaces of which guide grooves are made for support rollers. According to invention, strip is provided on each end of cage which encloses each row of rollers. Seal made, for instance, of felt overlapping cross section of guide groove for support rollers is secured on said strip by pressure plate and screw. Aperture is made in center of each of three plates of pack. Aperture in upper plate is made in form of hole of diameter corresponding to outer diameter of jack body. Apertures in middle and lower plates are square, with rounded off corners, with size of square side equal to sum of outer diameter of jack body and double value of maximum side displacement of device. Jack body is fitted in apertures of pack of three plates vertically, with blind end face pointed downwards, and slightly lifted over lower support of pack, and by other end face of which support flange is formed it is attached to upper plate of pack. Outer surface of jack body serves as travel limiter of middle and lower plates. Step bearing is installed on support spherical end of jack screw, said step bearing is provided with projection in form of square with narrowing end on support upper end face. Step bearing thrust by its upper end face against mating surface of bracket with load journal and flange for connecting equipment to frame. Square projection of step bearing gets into square socket of bracket. Three-link articulated mechanism is installed between step bearing and upper plate of pack so that axles interconnecting the links and connecting upper plate are parallel, and axle connecting hinge joint with step beating coincides with center of spherical end of jack screw, being orientated square to other axles of articulated three-link mechanism.

EFFECT: improved reliability of device and convenience in operation.
