钢轨扣件是连接钢轨与轨枕的重要部件。其主要作用在于保证钢轨与轨枕可靠的连接,在动力作用下充分发挥其弹性缓冲性能,以减缓线路残余变形积累的速度。我国已有的70型扣板式扣件和67型拱形弹片式扣件对大量推广钢筋混凝土轨枕的使用作出了积极的贡献。随着我国铁道建设事业的迅速发展,为了适应六大干线运量日益增长的需要、适应新型轨下基础
Rail fastening is an important part of connecting rail and sleeper. Its main role is to ensure reliable rail and sleeper connections, under the dynamic force to give full play to its elastic cushioning properties, in order to reduce the accumulation of residual speed deformation line. The existing 70-type buckle-plate buckle and 67-type dome-type buckle-type buckle in China have made a positive contribution to the extensive promotion of the use of reinforced concrete sleepers. With the rapid development of China’s railway construction, in order to meet the growing needs of the six main lines of traffic, to adapt to the new under-rail foundation
