Seismic isolation device for seismic protection platform

Abstract

The invention discloses a seismic isolation device for a seismic protection platform. The seismic isolation device comprises a ball I, a base, a limiting frame, a limiting device and a damping device,wherein the base is connected with the limiting frame, the ball I is arranged in a gap between the base and the limiting frame, the limiting device and the damping device are arranged at the two endsof the ball I respectively, and the two ends of the ball I extend out of the limiting frame and the base respectively. The seismic isolation device is reasonable in structure and convenient to use, and under the action of seismic waves, displacement of objects can be effectively avoided, and rollover of the objects is prevented.

Description

technical field [0001] The invention relates to the field of shock isolation technology, in particular to a shock isolation device for a shock absorber. 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 large range, ...

[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
