Rail vibration reduction fastener and rigidity adjustment design method thereof
A rail vibration reduction fastener is fixed on a sleeper and comprises a vibration reduction body cushioned on the sleeper, a bolt buckle plate assembly fixing the vibration reduction body on the sleeper, a rail gauge block pressing a steel rail on the vibration reduction body and an elastic strip installed on the vibration reduction body and pressing the rail gauge block. The damping device is characterized in that the damping body comprises a bottom plate and a top plate in vulcanization connection with the bottom plate through a rubber layer, vertical outer retaining shoulders are arranged on the two sides of the bottom plate, inner retaining shoulders which correspond to the outer retaining shoulders and are located on the inner sides of the outer retaining shoulders are arranged on the top plate, and the inner retaining shoulders are arranged on the outer sides of the steel rails. The rubber layer extends upwards from the bottom of the top plate to the position between the inner retaining shoulder and the outer retaining shoulder. The transverse rigidity and the transverse stability of the rail vibration reduction fastener are improved, the bearing requirements that the vibration reduction body is small in vertical load and small in rigidity and large in load and has limiting protection rigidity are met, the vibration reduction effect is guaranteed, and the driving safety is improved. The invention further provides a rigidity adjustment design method of the rail vibration reduction fastener.
一种轨道减振扣件，固定在轨枕上，包括垫在轨枕上的减振本体、将减振本体固定在轨枕上的螺栓扣板组件、将钢轨压紧在减振本体上的轨距块和装在减振本体上并压紧轨距块的弹条，其特征在于：所述的减振本体包括底板和通过橡胶层与底板硫化连接的顶板，底板两侧设有沿垂向的外挡肩，顶板上设有与外挡肩相对应且位于外挡肩内侧的内挡肩，内挡肩设置在钢轨外侧，橡胶层从顶板底部向上伸延至内挡肩和外挡肩之间。本发明增加轨道减振扣件的横向刚度，提高轨道减振扣件的横向稳定性，实现减振本体垂向小载荷小刚度、大载荷具有限位保护刚度的承载需求，保证减振效果，并提高行车安全性。本发明还提供一种轨道减振扣件的刚度调节设计方法。
