Embodiment Construction

[0035] Such as figure 1 As shown, an embodiment of the independent parallel link three-dimensional cultural relic seismic isolation device provided by the present invention includes a bottom plate 7 and a top plate 8 arranged in parallel, and four sets of independent The parallel link shock absorbers are arranged, and the four pairs of parallel link shock absorbers are arranged so that the projected connecting lines on the bottom plate form a rectangle.

[0036] Such as figure 2 , image 3 As shown, each pair of parallel link shock absorbers includes a parallel four-bar linkage mechanism, and the parallel four-bar linkage mechanism consists of an upper horizontal link 41, a left vertical link 51, and a lower horizontal link 42 and a right vertical connecting rod 52 are composed of four pin shafts 2 pivoted head-to-tail in turn, and a return spring mechanism is arranged on the pin shaft 2 at one of the diagonal positions of the parallel four-bar linkage mechanism. In the em...

Abstract

The invention provides a three-dimensional cultural object shock isolation device with independent-type parallel rods. The three-dimensional cultural object shock isolation device comprises a bottom plate and a top plate which are arranged in parallel, and four sets of parallel rod shock absorbers which are vertically connected between the bottom plate and the top plate and independently arranged; connection lines of projections of the four sets of parallel rod shock absorbers on the bottom plate form a rectangle; each set of parallel rod shock absorber comprises at least one parallel four bar mechanism, and the upper part and the lower part of the parallel four bar mechanism are pivotally connected with the top plate and the bottom plate respectively; and at least one reset spring mechanism which can enable the shock isolation device to keep in a balance position is arranged on the shock isolation device. Once an earthquake happens, due to the motion characteristic of the parallel four bar mechanisms, the top plate drives cultural objects to do a translational motion always, so as to prevent the cultural objects from inclining to fall off or slide off from the top plate; and the vibration impact can be weakened due to the elastic force and the damping force provided by the reset spring mechanism, and the cultural objects are prevented from damaging by shock waves of the earthquake.

Description

technical field [0001] The invention relates to a shock isolation device, in particular to a shock isolation device for placing movable cultural relics. Background technique [0002] The Palace Museum has more than 2 million movable cultural relics, accounting for 1 / 6 of the national cultural relics. These movable cultural relics are an important part of the world cultural heritage, with extremely important cultural, historical and cultural value, and the protection is of great significance. The protection of these cultural relics requires not only fire protection and anti-theft requirements, but also earthquake resistance requirements. On the one hand, Beijing is an 8-degree earthquake fortified area, and there have been many earthquakes in history. For example, since its establishment in 1420, Beijing has suffered at least 222 earthquakes, including 5 earthquakes with a degree of 8 or above. A large number of cultural relics earthquake damage shows that when the earthquak...
