Embodiment 1
[0026] see Figure 1~6 , in this embodiment, the vertical vibration isolation device of the three-dimensional vibration isolation device adopts the downward installation.
[0027]The three-dimensional seismic isolation device includes at least one three-dimensional seismic isolation device unit arranged between two embedded slabs 3, and the two embedded slabs 3 are respectively fixedly connected with the upper and lower bearing platforms 1 of the protected facilities or equipment through the connecting part. The part adopts the threaded connection method, that is, the internal thread of the connecting sleeve 2 embedded in the upper and lower platform 1 is matched with the external thread of the connecting bolt 9 fastening the embedded plate 3, and the three-dimensional seismic isolation device unit is composed of the upper and lower The horizontal vibration isolation device and the vertical vibration isolation device are installed vertically in series, and the vertical vibrati...
Embodiment 2
[0031] This embodiment is basically the same as Embodiment 1, especially in that:
[0032] In this example, see Figure 7 , the vertical seismic isolation device of the three-dimensional seismic isolation device adopts an upper installation, that is, the vertical seismic isolation device is placed on the top of the horizontal seismic isolation device, and the technical effect of using the three-dimensional seismic isolation device in the first embodiment can also be achieved.
Embodiment 3
[0034] This embodiment is basically the same as the previous embodiment, and the special features are:
[0035] In this embodiment, the materials of the vertical cylindrical elastic body 11 and the inclined cylindrical elastic body 8 are all rubber, and the rubber has a good elastic recovery ability, and can adapt to heavy-duty shock-absorbing occasions and other harsh environments. case.
