Embodiment Construction
[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0039] Such as figure 1 and figure 2 As shown, the present invention provides a universal ball bearing-sliding plate type shock isolation device for cultural relics, including a base plate 1, a base plate leveling screw 2, a dustproof plate 3, a lower plate 4, a support frame 5, a lower connecting frame 6, Lower rail 7, slider assembly 8, upper slide rail 9, upper connecting frame 10, upper plate 11, 4 damping rods 12, 4 springs 13 and a plurality of universal ball bearing assemblies 14 (universal ball bearing 20, adjustment Seat 21, lock nut 22);
[0040] A center hole is processed in the middle of the lower plate 4, and a plurality of universal ball bearing installation holes are arranged around the center hole;
[0041] The surface roughness of the upper surface of the bottom plate 1 is MRR Ra0.8, and the flatness is 0.06mm.
[0042] Both ends of t...

The invention discloses a universal ball bearing-sliding disc type cultural relic vibration isolating device which comprises a bottom plate, a lower plate, a support frame, a universal ball bearing, across damping resetting mechanism and an upper plate, wherein a central hole is machined in the middle of the lower plate; the lower plate is fixedly connected with the upper plate through the support frame; the lower end of the cross damping resetting mechanism penetrates through the central hole of the lower plate to be fixedly connected with the center of the bottom plate; the upper end of thecross damping resetting mechanism is fixedly connected with the upper plate; the bottom plate is in sliding fit with the lower plate through the universal ball bearing; and the bottom plate moves inthe horizontal direction to carry out vibration isolation and resetting through the cross damping resetting mechanism to prevent the displacement from being transmitted to the upper plate. The universal ball bearing-sliding disc type cultural relic vibration isolating device can carry a large-scale cultural relic and is excellent in vibration isolating effect.
Description
technical field [0001] The invention belongs to the technical field of shock isolation and shock absorption, and in particular relates to a universal ball bearing-sliding plate type shock isolation device for cultural relics. Background technique [0002] Precious cultural relics have important historical and cultural value, and protection is of great significance. Most of the precious cultural relics in the museum are in a floating state, which is easy to be damaged in an earthquake. There are a large number of floating cultural relics in our country's collections, but the traditional anti-seismic methods adopted in large quantities have limited effects, and there are problems that affect the appearance or even damage the cultural relics. Compared with domestic countries, Japan, the United States and other countries have adopted different types of cultural relics isolation devices, which played a key role in the protection of cultural relics in earthquakes.
