Problems solved by technology

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 i...

Embodiment 1

[0040] refer to figure 1 , discloses a shock-absorbing and isolation platform for the present application, including a horizontal foundation 1, and the horizontal foundation 1 includes a foundation plate 11. In actual use scenarios, the foundation plate 11 is set as a foundation plane such as the ground. Four support plates 12 in a rectangular array are placed on the upper surface of the base plate 11 , the support plates 12 are arranged as square plates, and the support plates 12 are placed on the base plate 11 through a leveling assembly 13 .

[0041] to combine figure 1 with figure 2, the leveling assembly 13 includes a support 131 placed on the base plate 11 , the support 131 is configured as a truncated cone, and four support 131 are respectively provided at the four end corners of the support plate 12 . A leveling bolt 132 is fixedly connected to the top of the support 131, and the leveling bolt 132 is arranged along the vertical direction. A connecting nut 133 corre...

Embodiment 2

[0054] to combine Image 6 with Figure 7 , a shock-absorbing platform, the difference from Embodiment 1 is that the upper link 512 and the lower link 514 are arranged along the distribution direction of the upper hinge shaft 511 and the lower hinge shaft 513, and the upper link 512 and the lower link 514 is always on the same horizontal line during the movement.

[0055] The end surface of the upper link 512 facing away from the upper hinge shaft 511 is provided with a sliding groove 5121, the sliding groove 5121 is arranged along the length direction of the upper connecting rod 512, and the sliding groove 5121 and the end of the lower connecting rod 514 facing away from the lower hinge shaft 513 Correspondingly, one end of the lower link 514 facing away from the lower hinge shaft 513 extends into the sliding groove 5121 and is slidably connected with the sliding groove 5121 . When the base plate 3 and the base plate 11 move relative to each other, the opposite ends of the ...

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 ...
