In-line vibration reduction fastener system
The invention discloses an in-line vibration reduction fastener system, which belongs to the technical field of steel rail fasteners and comprises a bottom plate, a second backing plate, a second elastic backing plate, a first backing plate, a bushing and a flat cushion block which are sequentially arranged from bottom to top, the first elastic backing plate and the second elastic backing plate which are arranged at the bottom of a steel rail form a double vibration reduction structure, and a connecting seat is arranged between the connecting seat and the bushing. The lining and the first base plate abut against each other in the transverse direction and the longitudinal direction, a stable connecting structure is formed between the lining and the first base plate, the cover plate on the lining abuts against the connecting base, so that the pre-tightening force applied by the anchor bolt is partially transmitted to the second elastic base plate, the elastic force loss of the second elastic base plate is reduced, and meanwhile the second elastic base plate is of a split embedded structure. And the blocking table and the limiting block are arranged at the two ends of the second base plate respectively, so that the overall transverse stability of the fastener system is improved. The fastener system can be widely applied to urban railways and has good application value.
本发明公开了一种直列式减振扣件系统，属于钢轨扣件技术领域，包括由下至上依次设置的底板、第二垫板、第二弹性垫板、第一垫板、衬套以及平垫块，其钢轨底部设置的第一弹性垫板和第二弹性垫板形成双减振结构，而连接座与衬套之间，衬套与第一垫板之间在横纵向上的相互抵接，彼此之间形成稳固的连接结构，并通过衬套上的盖板与连接座相抵接，使得锚固螺栓所施加的预紧力部分传递至第二弹性垫板，减小其弹力损失，同时，第二弹性垫板还采用分体镶嵌式结构，避免其产生较大的形变，从而确保扣件系统整体的稳定，在第二垫板的两端分别设置有挡台和限位块，提高扣件系统整体的横向稳定性。该扣件系统可广泛应用于市域铁路中，具有良好的应用价值。
