Abstract

The utility model provides an enhanced damping rubber shock insulation support which comprises a support body, the support body is provided with an upper support plate and a lower support plate, and a supporting main body is arranged between the upper support plate and the lower support plate. A plurality of buffer damping devices are evenly arranged on the lower support plate along the circumference and connected with one end of a steel strand assembly, and the other end of the steel strand assembly is connected to the upper support plate. And a plurality of limiting bases for limiting the moving range of the buffer damping device are arranged on the lower support plate corresponding to the buffer damping device. According to the shock insulation support, on the premise that a traditional rubber support is convenient to install and good in economical efficiency, the problem that a large equivalent damping ratio is difficult to provide under large displacement of the rubber support is solved, the multi-stage damping energy dissipation effect is achieved, the shock resistance of the support is remarkably improved, and the shock insulation support can meet the damping energy dissipation requirement under the large displacement of the support.
