Steel rail fastener and railway steel rail fastener system
The invention relates to the technical field of transportation equipment, in particular to a steel rail fastener and a railway steel rail fastener system.The steel rail fastener comprises a first screw spike, a second screw spike, an elastic strip and a gauge apron, the elastic strip defines a first mounting channel and a second mounting channel, and the gauge apron is provided with a first mounting hole and a second mounting hole; the first screw spike sequentially penetrates through the first mounting channel and the first mounting hole and is connected with the sleeper, the second screw spike sequentially penetrates through the second mounting channel and the second mounting hole and is connected with the sleeper, the elastic strip comprises two front end parts and two rear end parts, the two front end parts are used for being pressed on the side edge of the steel rail, and the two rear end parts are used for being pressed on the side edge of the steel rail. And the two rear end parts are pressed on the gauge apron. When the impact effect of a train with increased axle load on the track structure and the fastener is obviously increased, the impact force can be effectively released, the problem that the elastic strip is broken or the fastener is damaged or the steel rail climbs due to insufficient longitudinal resistance is avoided, and the running safety of the train is guaranteed.
本发明涉及运输装备技术领域，尤其涉及一种钢轨扣件及铁路钢轨扣件系统，钢轨扣件包括第一螺旋道钉、第二螺旋道钉、弹条和轨距挡板，弹条围设出第一安装通道和第二安装通道，轨距挡板设有第一安装孔和第二安装孔，第一螺旋道钉依次穿设于第一安装通道和第一安装孔，并与轨枕连接，第二螺旋道钉依次穿设于第二安装通道和第二安装孔，并与轨枕连接，弹条包括两个前端部和两个后端部，两个前端部用于压置于钢轨的侧沿，两个后端部压置于轨距挡板。在应对轴重增加的列车对于轨道结构和扣件的冲击效应明显增大时，可有效使冲击力释放，避免弹条断裂或扣件损坏，或者是由于纵向阻力不足发生钢轨爬行问题，保障列车的运行安全。
