FIELD: machine building.
SUBSTANCE: invention relates to lever mechanisms. Platform mechanism comprises support base and movable platform made in the form of equilateral triangles movably connected to each other by means of hinged connecting support device. Hinged connecting support device is made in form of a triangular moving platform connected to each other through vertices by means of three closed double-circuit kinematic circuits, links of which are made in the form of two-hinged connecting levers and are movably connected to each other, as well as with support base and moving platform through double cylindrical hinges with parallel to each other rotation axes. Inside each closed double-circuit kinematic chain hinged connecting support device in parallel to each side of triangle moving platform is installed hydraulic drive in form of movable hydraulic cylinder with located in it piston with rod.
EFFECT: simplified design of platform mechanism, reduced dimensions and increased stiffness at loading.
