Fastener system, ballast bed system, track system and installation method
The invention discloses the technical field of tramcars, and particularly relates to a fastener system, a ballast bed system, a track system and an installation method.According to the fastener system, a U-shaped groove of an anti-loosening washer is connected with a middle toe of an elastic strip in a clamped mode, so that blocking shoulders of the anti-loosening washer are clamped to the two side edges of a middle limb of the elastic strip, and the anti-loosening washer is clamped to the two side edges of the middle limb of the elastic strip by means of a part of anti-rotation torque provided by the elastic strip; the rotation of the lock washer is further limited, so that the anti-rotation and anti-loosening capability of the spike is improved when the fastener is mounted, and the maintenance requirement of a fastener system is reduced; according to the ballast bed system disclosed by the invention, the damping particles are arranged in the damping rubber base plate, so that the adaptability of the fastener to a monolithic ballast bed and a gravel ballast bed is realized; according to the rail system and the installation method, the installation method of the high-performance tramcar fastener system which is simple in structure, high in anti-loosening performance, high in stability, good in insulation performance and suitable for a monolithic track bed and a gravel track bed is provided according to the practical application conditions of tramcar fastener design, construction, operation and maintenance and the like.
本发明公开了有轨电车技术领域，具体涉及一种扣件系统、道床系统、轨道系统及安装方法，该扣件系统通过将防松垫圈的U形凹槽与弹条中趾卡接，使所述防松垫圈的挡肩卡在所述弹条中肢的两侧边，以借助弹条提供的一部分防旋转力矩，进一步限制防松垫圈的转动，从而提升了扣件安装时道钉的防旋转松退能力，减少了扣件系统的维护需求；本发明的一种道床系统，通过在阻尼橡胶垫板里设有阻尼颗粒，实现扣件对整体道床和碎石道床的适应性；本发明的一种轨道系统及安装方法，根据有轨电车扣件设计、施工及运维等实际应用情况，提供了一种结构简单、防松退性能强、稳定性强、绝缘性能良好、适应整体道床和碎石道床的高性能有轨电车扣件系统的安装方法。
