Tramcar rail fastener
The invention discloses a tramcar rail fastener. The tramcar rail fastener comprises an embedded sleeve, a gauge apron, an elastic strip and a screw spike, wherein the embedded sleeve is embedded in aconcrete sleeper, the gauge apron is installed on the two sides of a rail bearing groove of the concrete sleeper, the inclined face of the gauge apron is tightly attached to the inclined face of therail bearing groove, and a round hole of the gauge apron is aligned with a round hole of the embedded sleeve; a rubber base plate is placed on the concrete sleeper, and a steel rail is placed on the rubber base plate; a gauge block is installed between the gauge apron and the steel rail, and a plastic pad is installed in a groove of the gauge block; the tail end of the elastic strip is installed on the gauge apron, and the front end of the elastic strip is pressed on the plastic pad; and the screw spike penetrates through the round hole of the gauge apron and is screwed into the embedded sleeve to press the elastic strip and the steel rail. Compared with like products in the prior art, the tramcar track fastener can provide enough buckling pressure, vibration reduction performance and insulation performance for a track, and it can be guaranteed that the steel rail has enough track gauge adjustment amount and height adjustment amount.
本发明公开了一种有轨电车轨道扣件，包括预埋套筒、轨距挡板、弹条和螺旋道钉，其中：所述预埋套筒预埋于混凝土轨枕中，所述轨距挡板安装于混凝土轨枕的承轨槽两侧，轨距挡板的斜面与承轨槽的斜面密贴，轨距挡板的圆孔对准预埋套筒的圆孔；在混凝土轨枕上铺设橡胶垫板，在橡胶垫板上放置钢轨；在轨距挡板与钢轨之间安装轨距块，在轨距块的凹槽内安装塑料垫；所述弹条的尾端安装在轨距挡板上，弹条的前端压在塑料垫上；所述螺旋道钉穿过轨距挡板的圆孔拧进预埋套筒内，压紧弹条和钢轨。与现有技术相比，本发明的有轨电车轨道扣件能为轨道提供足够的扣压力、减振性能、绝缘性能，并能保证钢轨有足够的轨距调整量和调高量。
