Small-radius curve fastener structure for existing passenger and freight collinear railway
The small-radius curve fastener structure is used in cooperation with a small-radius curve sleeper, a rail bearing groove is formed in the small-radius curve sleeper, a rail bearing platform is formed in the rail bearing groove, and blocking shoulders are arranged on the left side and the right side of the rail bearing platform; the small-radius curve fastener comprises a screw spike, a T-shaped bolt, an elastic strip, a gauge baffle, an insulating baffle seat, an under-rail backing plate and an under-rail heightening backing plate; the gauge aprons are mounted at the two retaining shoulders respectively, a steel rail mounting position is arranged between the two gauge aprons, and each gauge aprons is fixed by matching a screw spike pre-embedded in the concrete sleeper with a first fixing assembly; the steel rails are mounted at the steel rail mounting positions and are downwards provided with rail lower base plates; insulation baffle seats are arranged between the gauge baffles and the steel rails. The passenger and freight collinear small-radius curve fastener is reasonable in design, simple in structure and more convenient to mount and dismount, and the problems that an existing passenger and freight collinear small-radius curve fastener is small in adjustment amount and inconvenient to maintain can be solved.
本发明公开了一种既有客货共线铁路用小半径曲线扣件结构，配合小半径曲线轨枕使用，小半径曲线轨枕上设有承轨槽，承轨槽内形成承轨平台，承轨平台左右两侧为挡肩；小半径曲线扣件包括螺旋道钉、T型螺栓、弹条、轨距挡板、绝缘挡板座、轨下垫板以及轨下调高垫板；两个挡肩处分别安装轨距挡板，两轨距挡板之间设置为钢轨安装位，每块轨距挡板用预埋于混凝土轨枕的螺旋道钉配合第一固定组件固定；钢轨安装在钢轨安装位，钢轨向下设有轨下垫板；轨距挡板和钢轨之间设置绝缘挡板座。本发明设计合理、结构简单、安装拆卸更方便，能够解决现有客货共线小半径曲线扣件中调整量小、维修不便的难题。
