Abstract

The invention discloses a three-dimensional shock isolation device. The three-dimensional shock isolation device comprises at least one three-dimensional shock isolation unit arranged between two embedded plates. Each three-dimensional shock isolation unit is composed of a horizontal shock isolation device and a vertical shock isolation device, wherein the horizontal shock isolation device and the vertical shock isolation are arranged in a vertical series connection mode. The horizontal shock isolation device is a vertical column-shaped elastic body arranged in a vertical mode in the axial direction, and the horizontal shock isolation device carries out elastic deformation through radial displacement deformation and torsion angle displacement deformation of the vertical column-shaped elastic body. The vertical shock isolation device is formed by parallel connection of at least three inclined column-shaped elastic bodies with equal dimensions so as to form a winding assembly body space structure, and therefore vertical deformation stood by the vertical shock isolation device is converted into inclined displacement and torsion placement of the inclined column-shaped elastic bodies. The three-dimensional shock isolation device can isolate three-way earthquake and environment vibration at the same time, and therefore shock / vibration response and shock / vibration delivery of a protected structure or device adopting the three-dimensional shock isolation device and under the effects of earthquake / the vibration can be controlled effectively, and safety under the effects of earthquake / the vibration can be guaranteed.

Description

Technical field [0001] The present invention involves a building, special structure, bridge, or mechanical equipment shock absorption / vibration device, especially a multi -angle seismic device, which is widely used in the field of environmental vibration and earthquake -proof and seismic technology. Background technique [0002] With the development of modern industries and the expansion of urban scale, the environmental vibration and noise problems caused by many vibrations such as industrial machinery and rail transit have gradually emerged. Environmental vibration has become one of the seven major harms affecting human life and production.Environmental vibration has a serious impact on the physical and mental health of humans, the comfort of living and living, and the production of precision instruments.For example, subway vibration affects the construction of buildings, the safety of ancient buildings, and the living environment of houses around the line.How to reduce small r...
