Elastic damping compression type high-grade vibration reduction split fastener for urban rail transit
The invention relates to an elastic damping compression type high-level vibration reduction split fastener for urban rail transit. The fastener comprises an elastic strip, a T-shaped bolt, eccentric positioners, anchor bolts and an iron base plate. The iron base plate is located below the steel rail, and the elastic strips are located on the two sides of the steel rail, staggered front and back to buckle the steel rail and fixed downwards through the T-shaped bolts. The eccentric positioners are located on the two sides of the steel rail, transversely correspond to the elastic strips and are fixed downwards through the anchor bolts. Compared with a common split fastener, the fastener structure of the invention has the advantages that the vibration reduction effect can be improved by 10 dB or above to the maximum extent, construction and installation of the track are convenient and fast, the fastener can be conveniently maintained in the track operation period, parts can be replaced, and the manufacturing cost of the track in a high vibration reduction section is remarkably reduced.
本发明涉及城市轨道交通用弹性阻尼压缩型高等减振分开式扣件，所述扣件包括弹条、T型螺栓、偏心定位器、锚固螺栓和铁垫板；铁垫板位于钢轨下方，弹条位于钢轨两侧，前后错开扣压钢轨并通过T型螺栓将弹条向下固定；偏心定位器位于钢轨两侧，横向与弹条对应，通过锚固螺栓向下固定。本发明的扣件结构，相对普通分开式扣件最大可提升减振效果10dB及以上，使轨道的施工安装方便快捷，使轨道运营期扣件可方便维修、零件可更换，且使高等减振地段轨道造价显著降低。
