Subway rail damping device
The invention discloses a subway rail damping device which comprises a rail. A bottom pad is arranged at the lower end of the rail, supporting plates are arranged at the lower end of the bottom pad, supporting rods are fixedly connected to the lower ends of the supporting plates, sleeves are arranged at the lower ends of the supporting rods, first grooves are formed in the sleeves, the supportingrods are slidably installed in the first grooves, and the supporting rods can slide up and down in the first grooves to drive the supporting plates to move up and down. The lower ends of the sleeves are integrally connected with bottom cylinders, second grooves are formed in the bottom cylinders, the lower ends of the supporting rods are integrally connected with bosses, the bosses are installed in the second grooves in a sliding mode, the diameter of the bosses is larger than that of the first grooves, first springs are arranged on the outer sides of the sleeves, one ends of the first springsare fixedly connected to the lower ends of the supporting plates, and the other ends of the first springs are fixedly connected to the bottom cylinders. Through the arrangement of the first springs,the downward moving speed of the supporting plates can be decreased through the first springs, the buffering effect on the rail is achieved, when a subway vehicle encounters an uneven road section, the first springs can further achieve the damping effect, and stable running of the subway vehicle is guaranteed.
本发明公开了一种地铁轨道减震装置，包括轨道，所述轨道下端设置有底垫，底垫下端设置有支撑板，支撑板下端固定连接有支撑杆，支撑杆下端设置有套筒，套筒内设置有凹槽一，支撑杆滑动安装在凹槽一内，支撑杆可在凹槽一内上下滑动，带动支撑板上下移动，所述套筒下端一体连接有底筒，底筒内设置有凹槽二，所述支撑杆下端一体连接有凸台，凸台滑动安装在凹槽二内，凸台的直径大于凹槽一的直径，所述套筒外侧设置有弹簧一，弹簧一一端固定连接在支撑板下端，弹簧一另一端固定连接在底筒顶端；通过设置弹簧一，弹簧一可减缓支撑板向下移动的速度，对轨道起到缓冲的作用，当遇到不平路段时，弹簧一还可起到减震的作用，保证地铁平稳的运行。
