Rail damping fastener
The invention relates to the field of rail traffic and particularly relates to a rail damping fastener. The rail damping fastener comprises an insulating sheath and two insulating gauge blocks, wherein the insulating sheath is mounted on a sleeper through fasteners, a mounting groove is formed in the insulating sheath, an under-plate elastic base plate and an iron base plate are sequentially mounted in the mounting groove in a matched mode from bottom to top, the under-plate elastic base plate makes contact with the sleeper, elastic pressing devices are arranged on the two sides of the upper portion of the iron base plate respectively, the two insulating gauge blocks are arranged on the two sides of the bottom of the steel rail respectively, the elastic pressing devices press the corresponding insulating gauge blocks, the pressing plates are fixedly installed on the two sides of an upper portion of the insulating sheath respectively, and the pressing plates make contact with an upper portion of one side of the iron base plate. The rail damping fastener is advantaged in that the structure is simple, the number of parts is small, the under-plate elastic base plate and the iron base plate are fixed in the transverse direction and the longitudinal direction by the insulating sheath through the mounting grooves, and the under-plate elastic base plate and the iron base plate are fixed in the vertical direction by the insulating sheath through the pressing plate, so displacement or deflection of the under-plate elastic base plate and the iron base plate is limited in all directions, and abrasion of the insulating sheath can be reduced.
本发明涉及轨道交通领域，具体是一种轨道减振扣件，包括绝缘包套和两个绝缘轨距块，绝缘包套通过紧固件安装在轨枕上，绝缘包套内开设安装槽，安装槽内由下而上的依次配合安装板下弹性垫板和铁垫板，板下弹性垫板与轨枕相触，铁垫板上部两侧分别设置弹性压紧装置，两个绝缘轨距块分别设置在钢轨底部两侧上，弹性压紧装置压紧对应的绝缘轨距块，绝缘包套上部两侧分别固定安装压板，压板与铁垫板的一侧上部相触。本发明的有益效果是，本发明结构简单且零部件少，绝缘包套通过安装槽将板下弹性垫板和铁垫板在横向和纵向固定，绝缘包套通过压板将板下弹性垫板和铁垫板在竖向固定，从而全方位限制两者位移或偏转，并能减少绝缘包套的磨损。
