Energy consumption three-dimensional vibration isolation bearing with tensile function

Abstract

The invention discloses an energy consumption three-dimensional vibration isolation bearing with a tensile function. The base comprises a shell, a horizontal vibration isolation system, a decoupling unit and energy consumption unit and a vertical vibration isolation system, wherein the shell comprises a peripheral plate, a rubber bearing limiting plate and a lower connecting plate, the horizontalvibration isolation system comprises a laminated lead core rubber bearing and an intermediate connecting plate which are connected with each other, the intermediate connecting plate is arranged at thebottom of the laminated lead core rubber bearing, and a disc-shaped spring upper loading limb is arranged on the edge side of the lower surface of the intermediate connecting plate; and the decoupling unit and energy consumption unit comprises a viscous liquid cavity, a piston and a viscous liquid, and the vertical vibration isolation system comprises a positioning pipe, a disc-shaped spring group, a spiral spring and a positioning loading ring. The bearing has the effective decoupling of horizontal and vertical movement, and is beneficial to the parameter design of the bearing, the tensile function is provided, so that the problem of overturning of the bearing is effectively solved, the bearing has large damping, the energy consumption effect of the support is improved, the vertical vibration isolation system with the rigidity self-adaptive characteristic is achieved, ground earthquake motion and environment vibration are both considered, and the advantages that the combination of all components is tight, and the space utilization rate is high are achieved.

Description

technical field [0001] The invention relates to the technical field of shock-isolation / vibration devices, in particular to an energy-consuming three-dimensional shock-isolation / vibration support with a tensile function. Background technique [0002] Vibration isolation technology has been widely researched and applied in the field of building structure isolation and vibration control of instruments and equipment. The basic principle of vibration isolation is to set a vibration isolation layer with low stiffness between the vibration-isolated / vibration body and its underlying foundation through a support or a special structure, and reduce the impact of external environmental vibration or earthquake vibration on the vibration-isolated area through the filtering effect. / vibration body (such as building structures, precision instruments, important historical relics, etc.) or prevent the vibration generated by the vibration isolation / vibration body (such as some large power m...

AI Technical Summary

Problems solved by technology

[0003] However, the existing vibration isolation devices have the following deficiencies: First, the current building isolation mainly stays at the stage of only isolating horizontal earthquakes and does not consider vertical earthquakes

Some existing three-dimensional vibration isolation devices can only play a role in one aspect; fourth, some existing three-dimensional vibration isolation bearings used in buildings are huge in size and often need to be used in conjunction with other energy-consuming devices, occupying too much space
