Three-dimensional shock-absorbing and isolation platform for floating object protection

Abstract

The invention provides a three-dimensional seismic mitigation and absorption platform for free standing object protection. The platform comprises a base plate, a rubber seat, a resetting spring, a vertical guide shaft support, a transverse guide shaft thick support, a transverse guide shaft thin support, a vertical damper unit, a transverse damper unit, an object placing plate, a connection shaft fixing clamp, a connection shaft, a transverse resetting spring short brace, a transverse resetting spring long brace, a vertical resetting spring short brace and a vertical resetting spring long brace. The three-dimensional seismic mitigation and absorption platform is compact in structure, has initial rigidity, is capable of achieving horizontal acceleration and displacement control of free standing objects under the effect of seism of different seismic levels by adjusting the damping force in the horizontal direction and capable of restraining vibration in the vertical direction, and enables the free standing objects to return to the initial position after the seism is finished.

Description

technical field [0001] The invention belongs to the technical field of shock absorption and isolation, and in particular relates to a three-dimensional shock absorption and isolation platform suitable for indoor floating objects such as art exhibits, precision instruments, and electronic equipment. Background technique [0002] For some important places, such as information centers, hospitals, museums, high-tech enterprises, etc., although the anti-seismic design of the building structure can ensure that the main structure will not suffer catastrophic damage during the earthquake, it is difficult to prevent the art placed on the indoor ground and countertops from being damaged. Hazards caused by floating objects such as exhibits, precision instruments, and electronic equipment due to overturning, collision with each other, or falling from the table. For indoor floating objects with great value, when an earthquake strikes, it is necessary not only to avoid damage to them, but...

AI Technical Summary

Problems solved by technology

It is difficult for traditional seismic design methods to meet this requirement, but if the seismic isolation technology is applied between the floating objects that need to be anti-seismic and the foundation, that is to separate the floating objects from the earthquake ground motion or foundation motion that may cause damage, The protection required above can be achieved by reducing the seismic force and energy transmitted to the floating objects
