Novel bolted fastener for urban rail transit
A novel bolted fastener for urban rail transit is used for effectively reducing the overturning of a steel rail and the dynamic stress of an elastic strip, improving the stability of the steel rail and greatly prolonging the fatigue service life of the elastic strip. The novel bolted fastener comprises an iron backing plate, an elastic strip, an under-rail elastic backing plate, a T-shaped bolt, alocknut, a special-shaped flying-preventing flat washer and insulating damping track gauge blocks, the iron base plate is fixedly installed on the under-rail foundation through anchor bolts, an under-plate elastic base plate is arranged below the bottom face of the iron base plate, and the steel rail is located on the iron base plate. The insulating damping track gauge blocks are located on the top face and the outer side of the steel rail bottom. The lower end of the T-shaped bolt is installed on the iron base plate, the upper portion of the T-shaped bolt is sleeved with the special-shaped anti-flying flat washer and the locknut to press the elastic strip, the front end of the elastic strip acts on the top face of the insulation damping gauge block, and the rear end of the elastic stripacts on an iron base plate boss.
一种用于城市轨道交通的新型有螺栓扣件，以有效减小钢轨倾覆及弹条的动态受力，提高钢轨稳定性，大幅度延长弹条疲劳使用寿命。包括铁垫板、弹条、轨下弹性垫板、T型螺栓、防松螺母、异型防飞平垫圈和绝缘阻尼轨距块；所述铁垫板由锚固螺栓安装固定在轨下基础上，板下弹性垫板设置于铁垫板底面之下，钢轨坐落在铁垫板上；所述绝缘阻尼轨距块位于钢轨轨底顶面及外侧；所述T型螺栓下端安装在铁垫板上，上部套装异型防飞平垫圈和防松螺母压紧弹条，弹条的前端作用于绝缘阻尼轨距块顶面上，后端作用铁垫板凸台上。
