Abstract

The invention provides a vibration isolation device with adjustable vertical rigidity. The vibration isolation device aims to solve the technical problem that the vertical rigidity of vibration isolation devices in the prior art cannot be adjusted. The vibration isolation device comprises a bottom plate, a top plate, shear tenons, at least three rubber vibration isolation assemblies and at least three adjustable spring supports, the top plate is located above the bottom plate and arranged opposite to the bottom plate at intervals, the lower ends of the shear tenons are fixedly connected to thebottom plate, and the upper ends of the shear tenons are elastically connected with the top plate; and each adjustable spring support comprises an upper base plate, a lower base plate, a steel spring, a connecting column, a sleeve and a fastener, the upper base plate is fixedly connected to the top plate, the lower base plate is fixedly connected to the bottom plate, the connecting column is vertically fixed to the lower base plate, the lower end of the steel spring is arranged on the connecting column in a sleeving mode and fixedly connected with the lower end of the connecting column, the sleeve is adjustably arranged on the outer wall of the connecting column in a sliding and sleeving mode and used for fixing part of the steel spring at the corresponding position of the sleeve to the connecting column so as to adjust the vertical rigidity between the bottom plate and the top plate, and the fastener is used for fixing the relative position of the sleeve on the connecting column.

Description

technical field [0001] The invention relates to the technical field of vibration control, in particular to a vibration isolation device with adjustable vertical stiffness. Background technique [0002] With the rapid development of urban construction, urban rail and road transportation networks are becoming more and more developed, ground transportation is becoming more and more saturated, and three-dimensional transportation combining underground and elevated transportation is increasing, which brings great convenience to people's travel. However, most of the traffic lines are close to or even pass through dense residential areas, commercial areas, cultural and educational areas, high-tech industrial parks, etc. in the city. The increasingly busy traffic lines will induce long-term environmental vibration pollution, seriously affecting the normal work and life of people along the line. Life, and the normal use of precision instruments and equipment in sensitive buildings. ...
