Product Description

本扣件系统在原有扣件结构的基础上重点对以下几方面进行优化改进:1)提高扣件系统的绝缘性能;2)提高弹条的疲劳性能;3)同时考虑可安装小扣压力弹条和摩擦系数小的复合垫板,具备小阻力扣件的功能。

1)系统组成

扣件系统由弹条、螺旋道钉、平垫圈、轨距挡板、轨下垫板和定位于预应力混凝土有挡肩枕的预埋套管组成。钢轨高低调整时采用调高垫板。

2)结构特征

本扣件为有螺栓扣件系统,属轨枕带混凝土挡肩的弹性不分开式扣件。扣件具有以下结构特征:

a)采用螺旋道钉与套管配合紧固弹条,提高了扣件系统的绝缘性能。

b)可安装多种弹条,既可安装大扣压力弹条也可安装小扣压力弹条。配合不同摩擦系数的轨下垫板(橡胶垫板或复合垫板),满足不同线路阻力的要求。

c)利用工程塑料制造的轨距挡板调整轨距并起绝缘作用,减少扣件部件数量,避免调整轨距时影响螺旋道钉的受力状态;

d)通过在轨下垫板与混凝土轨枕承轨面间垫入调高垫板实现钢轨高低调整。

4)配套轨枕接口技术要求

扣件系统对轨枕接口的技术要求主要是承轨槽的型式尺寸和轨枕中预埋套管的埋设位置和精度。既有IIIa型有挡肩预应力混凝土枕仅需在原钉孔位置按规定埋设预埋套管,弹条V型扣件系统便可与其相配套。
