Track damping device used in tunnel
The invention provides a track damping device used in a tunnel. The damping device is located under a track, the damping device comprises a top plate, a first buffering part, a second buffering part and a base which are sequentially arranged from top to bottom, the first buffering part comprises a first buffering piece and a first spring, the second buffering part comprises a second buffering piece and a second spring, the track is fixed on the top plate, the first buffering piece is fixedly connected with the top plate, the first buffering piece slides in the second buffering piece, the firstspring is connected between the first buffering piece and the second buffering piece in the sliding direction of the first buffering piece, the second buffering piece slides in the base, the second spring is connected between the second buffering piece and the base in the sliding direction of the second buffering piece, and the rigidity of the first spring is smaller than that of the second spring. The rigidity of the damping device can be freely changed, and when vibration is large, the overall rigidity of the damping device is also increased, and rapid damping can be achieved.
本发明提供一种用于隧道内的轨道减震装置，所述减震装置位于轨道正下方，所述减震装置包括自上而下依次设置的顶板、第一缓冲部、第二缓冲部以及基座，第一缓冲部包括第一缓冲件和第一弹簧，第二缓冲部包括第二缓冲件和第二弹簧，轨道固定于顶板上，第一缓冲件与顶板固定连接，第一缓冲件位于第二缓冲件内滑移，第一弹簧连接于第一缓冲件滑移方向上的第一缓冲件和第二缓冲件之间，第二缓冲件位于基座内滑移，第二弹簧连接于第二缓冲件滑移方向上的第二缓冲件和基座之间，第一弹簧的刚度小于第二弹簧的刚度。本发明减震装置的刚度可以自由变化，当震动较大时，减震装置整体的刚度也变大，能够快速减震。
