CABLE SEISMOPROTECTIVE PLATFORM Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention is intended for protection of electronic equipment racks and cabinets against seismoshock and low-frequency effects of large amplitude and duration transmitted through base in horizontal and vertical planes. Seismoprotective platform has rectangular frame and rectangular platform suspended inside it on elastic-damping cables for installation of object to be protected. Rectangular platform corners contain posts by means of which platform is suspended with provision for equal distances from its edges to walls of rectangular frame. Flexible-damping cables are passed through posts without slipping and touching of surface of rectangular platform positioned above flexible-damping cables which ends are passed through bushings installed in rectangular frame walls and are secured on ends of flat springs positioned outside along rectangular frame walls. Flat springs are fitted with devices for adjustment of tension of flexible-damping cables. Invention ensures enhanced protection of electronic equipment against seismoshock overloads and high-power low-frequency oscillations. EFFECT: higher efficiency. 2 cl, 1 dwg
