Seismic mitigation and isolation platform

Abstract

The invention discloses a seismic mitigation and isolation platform, and relates to the technical field of seismic isolation mechanisms. The seismic mitigation and isolation platform comprises a horizontal foundation. A placement bedplate is arranged in parallel right above the horizontal foundation, and at least three damping universal ball seismic isolation pieces which are not located on the same horizontal line are fixedly arranged on the horizontal foundation. A reset surface used for limiting the moving range of the placement bedplate is arranged on the placement bedplate, and ball bodies of the damping universal ball seismic isolation pieces abut against the reset surface. A limiting mechanism is arranged between the placement bedplate and the horizontal foundation and comprises a plurality of limiting assemblies, each limiting assembly comprises a connecting piece used for connecting the placement bedplate and the horizontal foundation, and the two ends of each connecting pieceare hinged to the placement bedplate and the horizontal foundation through an upper hinge shaft and a lower hinge shaft respectively. The distances between the axes of the lower hinge shafts and theaxes of the upper hinge shafts in the limiting assemblies can be synchronously adjusted. The seismic mitigation and isolation platform has an all-around damping effect on the articles placed on the placement bedplate in the horizontal plane.

Description

technical field [0001] The present application relates to the technical field of shock-isolation mechanisms, in particular to a shock-absorbing and isolating platform. Background technique [0002] Booths are mainly used to display cultural relics and other items in museums, cultural relics exhibition halls and other places, and the displayed items are generally placed on the platform of the booth. For example, when museum exhibits are displayed, they are usually required to be placed naturally without support and restraint. When encountering external forces such as earthquakes, naturally placed exhibits are easy to topple over and cause serious damage, resulting in huge economic and cultural losses. The safety of items under earthquake action is very necessary. [0003] Most of the existing isolation technologies are cross structure isolation devices (cross slides or cross rollers) and ball structure isolation devices. It can eliminate the vibration force in two vertical ...

For example, when museum exhibits are displayed, they are usually required to be placed naturally without support and restraint. When encountering external forces such as earthquakes, naturally placed exhibits are easy to topple over and cause serious damage, resulting in huge economic and cultural losses. The safety of items under the action of earthquakes is very necessary

[0003] Most of the existing isolation technologies are cross structure isolation devices (cross slides or cross rollers) and ball structure isolation devices. It can eliminate the vibration force in two vertical directions, but it is difficult to achieve all-round vibration isolation, and the vibration isolation effect is limited to a certain extent
