ANTISEISMIC PROTECTIVE PLATFORM Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: antiseismic protective platform has base in the form of external frame and horizontal platform located inside frame on ropes. Platform is intended for installation of protected object. Frame has horizontal ropes, longitudinally and transversely arranged, nontouching one another. Rope ends are secured in movable adapting devices installed along frame external sides. Adapting devices rest on torsion bars consisting of a set of flexible Z-shaped round rods assembled into flat packages installed along frame internal sides. Lower ends of rods are rigidly attached to frame. Upper ends of rods protrude in the form of levers and spaced relative to each other at a definite angle to provide for successive connection of flexible rods of torsion bars under action of adapting devices to which rope tensioning is transmitted during impact actions. Protective platform serves for protection of radioelectronic apparatuses and other objects from vibration and impact and seismic actions of high amplitude, low frequency and prolonged duration transmitted through base in vertical and horizontal planes. EFFECT: higher degree of protection of radioelectronic apparatuses and other objects. 1 dwg
