Fastener system suitable for heavy haul railway and installation method of fastener system
The invention discloses a fastener system suitable for a 35-45 ton heavy haul railway and an installation method thereof.The fastener system comprises a sleeper and a pre-embedded sleeve pre-embedded in the sleeper, an under-rail base plate is laid on a rail bearing face of the sleeper, a steel rail is placed above the under-rail base plate, gauge baffles are installed on the two sides of the bottom of the steel rail, and the pre-embedded sleeve is embedded in the sleeper. The inner side face of the gauge apron is matched with the bottom side face of the steel rail, the elastic strip is placed on the gauge apron, the toe end of the elastic strip is buckled on the steel rail, the flat washer is placed on the middle limb of the elastic strip, and the screw spike penetrates through the flat washer and the middle limb of the elastic strip and is screwed into the embedded sleeve. Compared with the prior art, the fastener steel rail has the advantages that the left-right position of the fastener steel rail can be adjusted by installing the gauge baffles of different models, and the requirement for transverse load resistance under the condition of 35-45 ton axle load can be met by matching with the sleeper shoulders. According to the fastener system, the number of parts is smaller, the manufacturing cost is lower, and the overall structure of the fastener system is more compact and stable.
本发明公开了一种适用于35～45吨重载铁路的扣件系统及其安装方法，扣件系统包括轨枕和预埋在轨枕中的预埋套管，在轨枕的承轨面上铺设轨下垫板，在轨下垫板上方安放钢轨，在钢轨轨底两侧安装轨距挡板，轨距挡板的内侧面与钢轨轨底侧面配合，在轨距挡板上放置弹条，弹条的趾端扣压在钢轨上，在弹条中肢上放置平垫圈，螺旋道钉穿过平垫圈和弹条中肢并旋入预埋套管中。与现有技术相比，本发明的积极效果是：本发明通过安装不同型号的轨距挡板可实现扣件钢轨左右位置的调整，配合轨枕挡肩可以满足35～45吨轴重条件下的抗横向载荷性能需求。本发明的扣件系统零部件数量更少，造价成本更低，扣件系统整体结构更为紧凑稳定。
