Vibration isolation device with adjustable vertical rigidity
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.
本发明提供了一种竖向刚度可调式隔振装置，以解决现有技术中隔振装置无法实现竖向刚度可调节的技术问题；包括底板、顶板、剪力卡榫和至少三个橡胶隔振组件和至少三个可调式弹簧支架，顶板位于底板的上方，并与底板相对间隔设置，剪力卡榫的下端固定连接于底板，上端与顶板弹性连接；每一可调式弹簧支架包括上基板、下基板、钢弹簧、连接柱、套筒和紧固件，上基板固定连接于顶板，下基板固定连接于底板，连接柱竖直固定于下基板，钢弹簧的下端套设于连接柱，并与连接柱的下端固定连接，套筒可调节的滑动套设于连接柱外壁，用于将套筒对应位置的部分钢弹簧固定于连接柱，以调节底板和顶板之间的竖向刚度，紧固件用于固定套筒在连接柱上的相对位置。
