Problems solved by technology
However, due to problems such as poor horizontal decoupling ability, poor torsion resistance, and low stability, or the complex structure of the isolation device and high production costs, the self-developed cultural relics isolation device has not been able to prevent cultural relics in domestic collections. Widely used in permanent shock protection

Embodiment Construction
[0028] The present invention is described in further detail below in conjunction with embodiment.
[0029] Such as Figure 1-Figure 3 As shown, the present invention is a wooden variable curvature rolling friction pendulum vibration isolation device for cultural relics, which is mainly used for vibration isolation of cultural relics in the horizontal direction. The vibration isolation support includes: lower track device 1, rolling device 2 and upper track device 3. The variable-curvature track two 14 and the variable-curvature track one 4 of the upper track device 3 and the lower track device 1 are in an orthogonal relationship. The upper and lower sides of the middle bearing plate 10 of the rolling device 2 are bearing supports 7 with rolling bearings 8 embedded with rolling shaft cores 9 . The wooden variable curvature track and the vertical anti-pull arc panel are pine wood, and other materials are stainless steel; the upper platform, the middle platform, the upper track ...

The invention relates to a wooden variable-curvature rolling type friction pendulum cultural relic shock insulation device. The device comprises a lower rail device, a rolling device and an upper rail device which are sequentially arranged from bottom to top; the lower rail device comprises a lower rail enclosing plate; a first wood variable-curvature rail and a wood vertical anti-pulling cambered surface plate are arranged in the lower rail enclosing plate; the upper rail device comprises an upper rail enclosing plate; a second wood variable-curvature rail and a damping rubber pad are arranged in the upper rail enclosing plate; and an upper bearing platform plate is arranged at the top of the upper rail enclosing plate. According to the wood variable-curvature rolling type friction pendulum cultural relic shock insulation device of the invention, design is carried out based on low sensitivity and high stability of a variable-curvature friction pendulum to an earthquake excitation frequency range, and a self-resetting function; the wood variable-curvature rails are adopted, so that the energy dissipation capacity of the shock isolation device can be improved; sliding friction is replaced by rolling friction, and the sensitivity of the device can be improved.
Description
technical field [0001] The invention relates to the technical field of protection of architectural cultural relics, in particular to a wooden variable-curvature rolling friction pendulum shock-isolation device for cultural relics. Background technique [0002] When exhibiting cultural relics in museums, in order to pursue the aesthetics of the cultural relics, most of them are floating. The cultural relics will have huge safety hazards under the action of the earthquake, especially the ceramic cultural relics, once the earthquake damage occurs, it will be irreversible. In the past, researches on the protection of cultural relics mostly focused on the cultural relics themselves, such as anti-corrosion and fire prevention, but the research on the anti-seismic and seismic isolation of cultural relics was obviously insufficient. However, the traditional anti-seismic measures for cultural relics are derived from practical experience and lack scientific basis. If the protection m...
