Embodiment Construction
[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.
[0038] Such as figure 1 As shown, the anti-vibration device 1 for cultural relics of the present invention includes a base 3, a first sliding seat 4 and a second sliding seat 5 stacked sequentially from bottom to top. Shock mechanism 6, vertical shock absorbing mechanism 6 among the present embodiment adopts prior art, such as PE foam etc.
[0039] The first sliding seat 4 can slide relative to the base 3 in the X direction of the horizontal plane, and the second sliding seat 5 can slide relative to the first sliding seat 4 in the Y direction of the horizontal plane, wherein the X direction and the Y direction are perpendicular to each other on the horizontal plane, so that Through the sliding ...

The invention discloses a cultural relic shock-proof device adopting the hybrid shock-absorbing technology. The cultural relic shock-proof device comprises a base, a first sliding seat and a second sliding seat which are sequentially stacked from bottom to top. The first sliding seat has an X-direction degree of freedom, the second sliding seat has a Y-direction degree of freedom, the X direction and the Y direction are parallel to the horizontal direction, and the horizontal projection of the X direction and the horizontal projection of the Y direction intersect. An active shock-absorbing mechanism and a passive shock-absorbing mechanism are arranged between the first sliding seat and the base, and an active shock-absorbing mechanism and a passive shock-absorbing mechanism are arranged between the first sliding seat and the second sliding seat. Each active shock-absorbing mechanism comprises a screw rod, a sliding sleeve and an accelerometer, wherein the screw rod is arranged in the X direction or the Y direction and driven by a motor, the sliding sleeve and the first sliding seat or the second sliding seat move synchronously, and the sliding sleeve is in threaded fit with the screw rod; the accelerometer detects the movement acceleration of the base or the first sliding seat and is used for outputting a signal for controlling the motor. By the adoption of the hybrid shock-absorbing technology, the displacement of a cultural relic relative to a showcase can be maintained below a safe threshold value while the acceleration of the cultural relic is greatly reduced, so that the device has high adaptability to various seismic wave motions.
Description
technical field [0001] The invention relates to an anti-shock device, in particular to an anti-shock device for cultural relics using a hybrid shock-absorbing technology for protecting movable cultural relics from earthquake damage. Background technique [0002] Among the many links in the anti-seismic protection of cultural relics, the anti-vibration of floating and displaying movable cultural relics is an important part. For the movable cultural relics stored in the warehouse, we can customize capsules, cushioning packaging and other methods to prevent shocks. These methods cannot be used for floating cultural relics. However, traditional shock-proof methods, such as: center of gravity drop method, fixed placement method (including sticking, suction, binding, etc.) , cards, supports, etc.) and the shock-absorbing cushion method, the effect is not good under the strong earthquake situation, and some methods even scratch and break the floating objects in the experimental res...
