Damping adjustment shock isolation device

Abstract

The invention discloses a damping adjustment shock isolation device. The damping adjustment shock isolation device comprises a sphere I, spheres II, a base, a damping device and a limiting frame, andis characterized in that a spherical groove is formed in the surface of the base, the limiting frame is connected with the base, the sphere I is limited between the limiting frame and the spherical groove through the limiting frame, the spheres II are arranged in a gap between the sphere I and the spherical groove, the damping device is arranged in the position, away from the base, of the limitingframe, the damping device generates frictional damping with the ball I, and the end of the ball I penetrates through the damping device and extends out of the limiting frame. The damping adjustment shock isolation device is reasonable in structure and convenient to use, under the action of seismic waves, displacement of objects can be effectively avoided, and rollover of the objects can be avoided.

Description

technical field [0001] The invention relates to the technical field of shock isolation, in particular to a damping adjustment shock isolation device. 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, and...

[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
