Abstract

The invention discloses a ball plate earthquake-isolation platform with the functions of return, overturn prevention and buffering. The ball plate earthquake-isolation platform with the functions of return, overturn prevention and buffering comprises a lower plate fixed to the ground or fixed to a plane, an upper plate used for installing an earthquake-isolation object, and an edge surrounding plate used for connecting the upper plate and the lower plate, wherein a plurality of universal bolts used for supporting the upper plate are arranged at the top of the edge surrounding plate; and a flatball plate, a first earthquake-isolation assembly, a second earthquake-isolation assembly, a third earthquake-isolation assembly and a fourth earthquake-isolation assembly are arranged between the upper plate and lower plate. The earthquake-isolation platform is simple in structure, reasonable in arrangement, and convenient to use, applies an insulation and earthquake-isolation principle, has a movement function of the flat ball plate, the functions of rubber friction resistance and liquid viscous damping, an overturn-prevention limit function, and the return function of a spring, consumes the influence of earthquake on equipment, and prolongs the period of electromechanical equipment; and compared with the prior art, the displacement and acceleration response caused to the large preciseelectromechanical equipment by earthquake can be much greatly reduced, and especially, the earthquake-isolation capacity of the electromechanical equipment under the effects of frequent earthquake earthquake and rare occurrence earthquake is improved. The product can be used independently, and a plurality of the products can be used in a combined manner, so that a large-area earthquake-isolation effect is formed.

Description

technical field

[0001] The invention relates to the technical field of shock isolation devices, specifically a ball plate shock isolation platform with homing, anti-tilt and buffering, which is mainly used in precision data cabinets, control electric cabinets, precious cultural relics and large-area integrity earthquakes Protection, using the principle of seismic isolation to ensure that the protected object is not damaged when a strong earthquake occurs, and the functional integrity is guaranteed. Background technique

[0002] As an important data carrier of modern telecommunications and Internet systems, large-scale precision data cabinets are often placed freely or fixedly connected on the floor. Its high center of gravity and heavy weight transmit and amplify the surface seismic waves and their floors. Under the environment, it is easy to cause resonance to cause large displacement or even collapse, resulting in irreparable and serious losses such as equipment failure, d...
