Double-curved-surface isolation platform

Abstract

The invention discloses a double-curved-surface isolation platform. The double-curved-surface isolation platform comprises a bottom table plate, a floating plate, a supporting frame and a universal guide mechanism; a plurality of lower curved surface grooves which are evenly distributed in the circumference are formed in the upper surface of the bottom table plate; a plurality of upper curved surface grooves which are evenly distributed in the circumference are formed in the lower surface of the floating plate; the bottom table plate and the floating plate are connected through the universal guide mechanism; the supporting frame comprises a plate frame and supporting columns; a plurality of supporting columns are evenly distributed in the circumference and vertically arranged on the outer periphery of the plate frame; the supporting columns are supported between the lower curved surface grooves and the upper curved surface grooves; curved surface protruding heads are arranged at the upper ends and the lower ends of the supporting columns; and the supporting columns, the lower curved surface grooves and the upper curved surface grooves are arranged in a one-to-one correspondence manner. According to the double-curved-surface isolation platform, damping between the supporting frame and the floating plate and between the supporting frame and the bottom table plate is increased, shaking caused by accidents is reduced, and exhibition cultural relics show stable visual perception.

Description

technical field [0001] The invention relates to the field of anti-vibration technology, in particular to a hyperboloid isolation platform. Background technique [0002] Earthquake is a sudden natural disaster, and a large earthquake can cause extremely serious damage. Since humans cannot accurately predict the occurrence of earthquakes, it is particularly important to prevent and mitigate earthquake disasters. The existing anti-seismic device for cultural relics is a device installed on the bottom of cultural relics, display cabinets or precision instruments, which avoids the excellent frequency of seismic waves and effectively absorbs seismic waves under the action of earthquakes, thereby isolating seismic waves and protecting cultural relics. [0003] The two-dimensional anti-vibration platform means that the upper floating plate can slide in the horizontal direction. When the earthquake only shakes in the horizontal direction, the anti-shock effect can be achieved. There...

Problems solved by technology

However, due to the limitation of the structure size, it is impossible to have a large gap between the upper table and the lower table, so the diameter of the rolling ball is small, resulting in a small contact area between the ball and the concave structure, and the resistance is small. Accidental collision or vibration can easily cause shaking and cause visual impact, which is not conducive to the exhibition of cultural relics
