Damping ball type anti-torsion seismic isolation table

Abstract

The invention discloses a damping ball type anti-torsion seismic insulation table. The damping ball type anti-torsion seismic insulation table comprises a base, an upper panel, damping adjusting universal ball devices and a connecting rod mechanism, wherein the damping adjusting universal ball devices are arranged on the base and used for supporting the upper panel; the damping adjusting universalball devices are arranged between the base and the upper panel, and the base and the upper panel are connected through the connecting rod mechanism; a connecting rod device of the connecting rod mechanism does plane translational motion, and the connecting rod device does not rotate; and the damping adjusting universal ball devices are connected through connecting devices I, so that the relativepositions of the damping adjusting universal ball devices are not changed. According to the damping ball type anti-torsion seismic insulation table, the structure is reasonable, using is convenient, and object displacement can be effectively avoided under the action of seismic waves.

Description

technical field [0001] The invention relates to the technical field of shock isolation, in particular to a damping ball type anti-rotation shock isolation table. Background technique [0002] Existing high-value items used for cultural relics protection or Internet servers require shock-isolation platforms for shock-absorbing protection. Most of the existing shock-isolation technologies are cross-structure shock-isolation devices (cross slides or cross rollers) and ball bearings. However, the cross-structure seismic isolation device has dead angles and blind areas in the direction of the source, so it cannot achieve all-round vibration isolation. Although the ball structure has no dead angles and blind areas in azimuth, under the action of seismic waves, the device supports After the object is subjected to the action of the earthquake wave, due to the excessive inertia and motion acceleration of the object, the shock isolation device of the ball mechanism will move in a larg...

[0002] Existing high-value items used for cultural relics protection or Internet servers require shock-isolation platforms for shock-absorbing protection. Most of the existing shock-isolation technologies are cross-structure shock-isolation devices (cross slides or cross rollers) and ball bearings. However, the cross-structure seismic isolation device has dead angles and blind areas in the direction of the source, so it cannot achieve all-round vibration isolation. Although the ball structure has no dead angles and blind areas in azimuth, under the action of seismic waves, the device supports After the objects are subjected to the action of the earthquake wave, due to the excessive inertia and motion acceleration of the objects, the shock isolation device of the ball mechanism will move in a large range, and then drive the objects to move in a large range. The effect of the shock isolation rate is poor, up to Less than the seismic isolation standard
