Multi-layer fastener with shoulder
The invention provides a multi-layer fastener with a shoulder, comprising an upper pad, a lower pad and a middle elastic pad arranged between the upper pad and the lower pad, and further comprising ashoulder structure and a supporting column, wherein the shoulder structure adopts a form combining an inner shoulder with an outer shoulder, an isolation layer is arranged between the inner shoulder and the outer shoulder, a first through hole is formed in the upper pad, the supporting column passes through the first through hole, a pressing sleeve is mounted in the first through hole, and the pressing sleeve sleeves outside the supporting column. The multi-layer fastener with the shoulder provided by the invention is simple in structure, can effectively prevent the upper pad from rotating orturning over through a matching form of the inner shoulder and the outer shoulder, thus preventing a steel rail from turning over and improving traveling safety.
本发明提供了一种带挡肩的多层扣件，包括上垫板、下垫板以及设置在上垫板与下垫板之间的中间弹性垫，还包括挡肩结构和支撑柱，所述挡肩结构采用内挡肩和外挡肩组合的形式，所述内挡肩和外挡肩之间设置隔离层，所述上垫板上设置第一通孔，所述支撑柱穿过所述第一通孔，所述第一通孔内安装压紧套，所述压紧套套设在支撑柱的外部。本发明提供的带挡肩的多层扣件结构简单，通过内挡肩和外挡肩配合的形式，能够有效抑制上垫板旋转或翻转，进而抑制钢轨翻转，提高行车安全。
