Steel rail supporting device with vibration and noise reduction effects
The invention relates to the field of rail transit, in particular to a steel rail supporting device with vibration and noise reduction effects. Thesteel rail supporting device comprises a fixing plate, the fixing plate is mounted on a sleeper through a fastener, an elastic energy consumption device is arranged on the fixing plate, a supporting plate is arranged on the elastic energy consumption device, an elastic sheet is arranged on the supporting plate, and two ends of the elastic sheet are positioned on two sides of a rail web; and gaskets are arranged between the rail web and the end parts of the elastic sheet on the corresponding sides. The steel rail supporting device has the beneficial effects that a plurality of structures are arranged between damping fasteners at intervals, the constraint degree and integrity of a track plate and a steel rail are improved through the elastic energy dissipation device, the vibration form of the steel rail is changed, and continuous supporting of the steel rail is approximately achieved; periodic abrasion of the wheel rail caused by small rigidity of the fastener and discrete support can be effectively inhibited; the gasket is tightly attached to the rail web, so that the structural damping of the rail is greatly improved, the function of reducing high-frequency radiation noise of a wheel rail is achieved, steel rail rollover when a vehicle passes through a curve can be limited, and wheel rail abrasion caused by steel rail rollover is reduced.
本发明涉及轨道交通领域，具体是一种具有减振降噪效果的钢轨支撑装置，包括固定板，固定板通过紧固件安装在轨枕上，固定板上设置弹性耗能装置，弹性耗能装置上设置支撑板，支撑板上设置弹片，弹片的两端位于轨腰两侧，轨腰与对应侧的弹片端部之间设置垫片。本发明的有益效果是，本发明通过将数个这种结构间隔设置在减振扣件之间，通过弹性耗能装置提高轨道板与钢轨的约束程度和整体性，改变钢轨的振动形态，近似实现钢轨的连续支撑，可有效抑制由于扣件小刚度和离散支撑所导致的轮轨周期性磨耗；通过垫片紧贴轨腰，大大提高了轨道的结构阻尼，具有降低轮轨高频辐射噪声的功能，还可以限制车辆曲线通过时的钢轨侧翻，减少由此引起的轮轨磨耗。
