The three-dimensional shock-insulation device capable of presetting the vertical early stiffness includes a laminated rubber shock-insulation support and a vertical shock-insulation support, wherein the laminated rubber shock-insulation support and the vertical shock-insulation support are sequentially connected in series from top to bottom. The three-dimensional shock-insulation device capable of presetting the vertical early stiffness is characterized in that a back-pressing device is further arranged between two end plates of the vertical shock-insulation support and includes two sets of prepressing steel cables and two floating platens, wherein the number of each set of the prepressing steel cables is at least three, the two floating platens are respectively arranged on a guide rod between one end plate and a belleville spring set in a sleeving mode; the two sets of the prepressing steel cables are symmetrically distributed on the periphery of the belleville spring set around the axis of the guide rod in a linear state, one ends of each set of the prepressing steel cables are fixed to one corresponding floating platen, the other ends of each set of the prepressing steel cables penetrate through the other corresponding floating platen and are fixed to the end plate adjacent to the floating platen; and the two sets of the prepressing steel cables are tensioned so as to clamp the belleville spring set between the two floating platens all the time.

The invention discloses an adjustable vertical early-stage rigid three-dimensional shock insulation support. The three-dimensional shock insulation support comprises a laminated rubber shock isolation support and a vertical shock isolation support which are vertically and serially connected in sequence and is characterized in that a reverse pressing device is further arranged in a guiding sleeve of the vertical shock isolation support and comprises two groups of pre-pressing steel cables and two floating press plates, the two groups of pre-pressing steel cables are distributed between a rubber air spring and the guiding sleeve, one end of one group of pre-pressing steel cables is fixed to the corresponding floating press plate adjacent to a driving press plate, and the other end of the group penetrates through the corresponding floating press plate adjacent to base to be anchored on the base through a steel cable self-locking and tensioning anchor. One end of the other group of pre-pressing steel cables is fixed to the corresponding floating press plate adjacent to the base, and the other end of the other group of pre-pressing steel cables penetrates through the corresponding floating press plate adjacent to the corresponding driving press plate to be anchored on the corresponding driving press plate through a steel cable self-locking and tensioning anchor. The two groups of pre-pressing steel cables are tensioned, so that the rubber air spring is always clamped between the two floating press plates.
