Track floating slab vibration isolator
The invention belongs to the technical field of rail vibration and noise reduction, and particularly discloses a rail floating slab vibration isolator which comprises a fixed sleeve, a height adjusting sleeve and a vibration reduction assembly. The vibration reduction assembly comprises a supporting unit and a bearing unit located above the supporting unit, and a vibration isolation unit, a damping unit and a protection unit formed by a rubber-metal composite structure are arranged between the supporting unit and the bearing unit. Stepless height adjustment of the floating slab can be achieved, meanwhile, when the track bears a small load, the vibration isolation unit and the damping unit act together to provide vibration reduction efficiency, and when the track bears a large load, the protection unit participates in bearing and acts together with the vibration isolation unit and the damping unit to provide rigidity support and generate vibration reduction efficiency. And good vibration isolation capacity and bearing capacity are achieved.
本发明属于轨道减振降噪技术领域，具体公开了一种轨道浮置板隔振器，包括固定套筒、调高套筒和减振组件；减振组件包括支撑单元和位于支撑单元上方的承载单元，支撑单元和承载单元之间设有隔振单元、阻尼单元和由橡胶金属复合结构形成的保护单元。本发明可实现浮置板的无极调高，同时当轨道承受小载荷时，由隔振单元和阻尼单元共同作用提供减振效能，当轨道承受大载荷时，保护单元参与承载并与隔振单元、阻尼单元共同作用提供刚度支撑并产生减振效能，具有良好的隔振能力和承载能力。
