Embodiment 1

[0025] like figure 1 As shown, a sliding vibration isolation platform according to the present invention includes three main parts of a stage 7, an intermediate layer 6 and a base 1, and a rubber gasket 8 is arranged on the stage 7, and on the rubber gasket 8 Display items 9, such as fragile cultural relics, can be placed.

[0026] The vibration isolation table includes two layers of vertically arranged guide rails 2, and each layer of sliding table needs at least four steel balls 3. In order to ensure the stability of the sliding table during the rolling process, the friction consistency of the four steel balls during the rolling / sliding process is required to be relatively high, so that the sliding table will not roll due to inconsistent resistance of the rollers during the movement. deflection etc.

[0027] In this embodiment, two X-direction sides of the base 1 are respectively provided with two end-to-end guide rails 2, and the size of each guide rail 2 is the same; si...

Abstract

Provided is a sliding seismic isolation platform which can isolate external disturbance and prevent an exhibited valuable article from being toppled and damaged. When the bottom of the sliding seismic isolation platform suffers from impact of horizontal external force, an article stage can freely reciprocate along X-direction arc-shaped rails and Y-direction arc-shaped rails, external impact is isolated, and the article placed on the article stage remains stable. After the external force disappears, the article stage can return to the initial position under the action of self-gravity. Movement damping of the sliding seismic isolation platform can be adjusted continuously, and therefore a system seismic isolation period is controlled, and the applicable range of the seismic isolation platform is widened.

Description

technical field [0001] The invention relates to a mechanical device capable of isolating external disturbances and preventing valuables on display from being overturned and damaged. In particular, it is a simple and reliable two-dimensional seismic isolation table that can work stably for a long time and is convenient for maintenance and adjustment. Background technique [0002] When an earthquake suddenly occurred, many precious cultural relics were damaged. Compared with the past, the seismic capacity of modern museum building structures has been significantly improved. Although the building may not collapse in an earthquake, the severe vibration and impact caused by sudden earthquakes may cause the fragile items placed in the display cabinets to fall and collide. , damage, or even cause irreparable losses. If the display items are fixed by binding, bonding, etc., it will not only seriously affect the ornamental value, but also bring new damage to some fragile items. Th...
