Rubber vibration isolator for floating slab track
The invention discloses a rubber vibration isolator for a floating slab track, and aims to effectively improve the vibration isolation performance, randomly adjust the height of the rubber vibration isolator, realize a three-way limiting function, facilitate installation, replacement and maintenance, and reduce the construction difficulty and the laying workload. The isolator comprises an upper support, a rubber block and a lower support which are assembled into a whole through a central shaft column. The central shaft column is provided with an upper threaded section and a lower inverted-T-shaped structure, the upper threaded section upwards penetrates through a central circular hole of the lower support and a central hole of the rubber block from an annular cavity in the bottom of the lower support and then is in threaded connection with a central hole of the upper support, and the rubber block is pre-compressed. An embedded limiting column is fixedly arranged on the base ballast bed, and the top of the embedded limiting column protrudes into an annular cavity in the bottom of the lower support. When the rubber vibration isolator bears axial and lateral strong impact, the lower inverted-T-shaped structure makes limiting contact with the lower pre-buried limiting column and a central circular hole of the lower support, and three-way limiting is achieved. A height adjusting device is detachably mounted on the top surface of the upper support.
一种用于浮置板轨道的橡胶隔振器，以有效提高隔振性能，且能够随意调节自身高度，并可实现三向限位的功能，便于安装、更换和维护，减少施工难度和铺设工作量。包括通过中心轴柱装配为一体的上支座、橡胶块和下支座；所述中心轴柱具有上部螺纹段和下部倒T型结构，上部螺纹段由下支座底部环形腔室向上穿过下支座中心圆孔、橡胶块中心孔后与上支座中心孔螺纹连接，对橡胶块形成预压缩；所述基底道床上固定设置预埋限位柱，预埋限位柱顶部凸入下支座底部环形腔室内。所述橡胶隔振器承受轴向、侧向强力冲击时，下部倒T型结构与下方预埋限位柱、下支座中心圆孔产生限位接触，实现三向限位；所述上支座顶面上可拆卸安装调高装置。
