Damping device for shock insulation support seat

Abstract

The invention relates to a damping device for a shock insulation support seat. The damping device comprises a screw rod, a coordination sleeve and rotary damping mechanisms, wherein the coordination sleeve is installed on the screw rod, the inner wall of the coordination sleeve is provided with a ball, the ball is embedded into a thread groove of the screw rod and is used for performing rolling coordination along an extension trajectory of the thread groove, and one end or the two ends of the screw rod are connected with the rotary damping mechanisms. According to the damping device for the shock insulation support seat, the screw rod is rotatably installed on the shock insulation support seat, the coordination sleeve is connected with a cultural relic base, when the cultural relic base issubjected to shock impacting, the cultural relic base transmits horizontal-direction impacting force to the coordination sleeve, the ball inside the coordination sleeve moves along the thread grooveof the screw rod to drive the screw rod to rotate, the horizontal-direction impacting force on the cultural relic base is converted into rotating force of the screw rod, primary buffer shock absorption of the cultural relic base horizontal-direction impacting force is realized, the rotary damping mechanisms are used for reducing the rotating speed of the screw rod, shock energy is further absorbed, secondary buffer shock absorption of the cultural relic base horizontal-direction impacting force is realized, and the damping device for the shock insulation support seat has better protection on cultural relics.

Description

technical field [0001] The invention relates to the technical field of buffering and shock absorption of cultural relics, in particular to a damping device for a shock-isolation support. Background technique [0002] my country is located between the circum-Pacific seismic belt and the Eurasian seismic belt, and most of the land is located in earthquake-prone areas. [0003] More than half of the museums in our country are located in high-intensity areas of degree VI and above, with frequent earthquakes, and each earthquake disaster has extremely serious damage to the cultural relics displayed in the museums, which has brought us painful lessons. [0004] The cultural relics in the museum collection have important cultural, historical and artistic value, and their protection is of great significance. [0005] Most of the cultural relics in the collection are mainly floating, and their movement characteristics are mainly sliding, shaking, torsion and overturning under the ac...

AI Technical Summary

Problems solved by technology

These methods can only improve the anti-seismic performance of cultural relics to a certain extent, and have poor buffering and shock-absorbing effects on horizontal impact forces; most of the existing shock-isolation bearings do not use special damping devices for energy absorption and shock absorption, and cannot be replaced. Effectively suppress the vibration amplitude of cultural relics
