The invention discloses a damping subway rail device which solves the problems that in the prior art, the shock absorption effect cannot meet the requirement, and the maintenance cost is high. Dampingliquid can have the energy absorption and shock absorption effects at the same time, and meanwhile rapid shock absorption can be achieved in cooperation with springs. According to the technical scheme, the device comprises a rail, a supporting plate, a first base and a second base, the first base is arranged above the second base, and the two ends of the first base and the two ends of the secondbase are connected through first springs respectively; the supporting plate is installed above the first base through an automatic aligning structure, and the rail is fixed to the top of the supporting plate. A cavity is formed in the second base, and a second spring is arranged in the cavity and filled with the damping liquid; the bottom of the first base is connected with pistons; a channel is formed in the inner wall of the second base; a first one-way valve is mounted at the joint of the channel and the bottom of the second base; a plurality of throttling openings are formed in the axial direction of the piston and provided with second one-way valves. The piston can move downwards under the action of vibration, and the cavity is divided into an upper cavity and a lower cavity.
本发明公开了一种减震地铁轨道装置，它解决了现有技术中减震效果不能满足要求、维修成本较高的问题，阻尼液能够同时具有吸能减震的效果，同时配合弹簧能够快速减震。其技术方案为：包括轨道、支撑板、第一基座和第二基座，第一基座设置于第二基座上方，第一基座与第二基座的两端分别通过第一弹簧相连；支撑板通过自动调心结构安装于第一基座上方，轨道固定于支撑板顶部；第二基座内部具有腔室，腔室内设置第二弹簧且填充有阻尼液；第一基座底部连接活塞；第二基座内壁设有通道，通道与第二基座底部的连接位置安装第一单向阀；沿活塞轴向设置多个节流口，节流口安装第二单向阀；在震动作用下活塞能够下移，并将腔室分隔成上腔和下腔。
