An energy-dissipating three-dimensional vibration-isolation bearing with tensile function

Abstract

The invention discloses an energy-dissipating three-dimensional vibration isolation bearing with a tensile function, which comprises: a shell, including a peripheral plate, a rubber bearing limit plate and a lower connecting plate; a horizontal vibration isolation system, including interconnected laminations A lead-core rubber support and an intermediate connecting plate, the intermediate connecting plate is arranged at the bottom of the laminated lead-core rubber support, wherein the lower surface side of the intermediate connecting plate is provided with a disc spring upper loading limb; the decoupling unit and the energy dissipation Unit, including viscous liquid chamber, piston and viscous liquid; vertical vibration isolation system, including positioning tube, disc spring group, coil spring and positioning loading ring. The invention has effective decoupling of horizontal and vertical motion, which is beneficial to the parameter design of the bearing; has a tensile function, effectively solves the problem of the bearing overturning; has greater damping and improves the energy consumption effect of the bearing; The vertical vibration isolation system with adaptive characteristics takes into account the ground vibration and environmental vibration; the components are closely combined and the space utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of vibration isolation devices, in particular to an energy-consuming three-dimensional vibration isolation 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 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 body ( Such as the impact of building structures, precision instruments, important historical relics, etc.) or prevent the vibration generated by the vibration isolation body (such as some large power machinery equipment) from propagating to its underlying foundation....

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
