Stretching type rail fastener
The invention relates to a stretching type rail fastener. The fastener comprises a damping alloy energy dissipation assembly, a rubber cushion plate supporting assembly and a steel rail restraining assembly. The rubber base plate supporting assembly is connected with the steel rail restraining assembly and used for embedding a steel rail, and the damping alloy energy dissipation assembly is arranged on a sleeper and hinged to the steel rail restraining assembly. Compared with the prior art, the buckling system has broadband energy dissipation capacity, damping alloy is adopted, the buckling system has a good energy dissipation effect on low-frequency vibration and high-frequency vibration in a tensile elastic deformation state, and the problems that in a traditional buckling system, energy dissipation of a viscoelastic material element depends on large deformation, large deformation is not in time, rebounding is not in time, and energy dissipation is poor are effectively solved. And therefore, the technical bottleneck problem is solved. The system is safe and reliable, and due to the two-stage energy dissipation and vibration reduction structure of the damping alloy energy dissipation assembly and the rubber cushion plate supporting assembly, safe operation of a train in an extreme environment can be guaranteed.
本发明涉及一种拉伸型轨道扣件，该扣件包括：阻尼合金耗能组件、橡胶垫板支撑组件和钢轨约束组件；所述橡胶垫板支撑组件与钢轨约束组件连接，用于使钢轨嵌设在内，所述阻尼合金耗能组件设置在轨枕上，并与钢轨约束组件铰接。与现有技术相比，本发明具有宽频耗能能力：由于采用了阻尼合金，其在拉伸弹性变形状态对低频和高频振动都有很好的耗能作用，有效改善了传统扣件系统中黏弹性材料元件耗能依赖于大变形、而大变形回弹不及时，从而影响其耗能效率的技术瓶颈问题。本发明安全可靠，由于具备阻尼合金耗能组件和橡胶垫板支撑组件两级消能减振结构，能保证在极端环境下列车的安全运行。
