Railway viaduct track damping device
The invention discloses a railway viaduct track damping device which comprises a railway track and sleepers, buffer pads are arranged between the railway track and the sleepers, limiting seats are arranged at the two ends of each sleeper, the limiting seats are fixedly connected to the upper side of the railway track, sliding grooves are formed in the opposite sides of the two limiting seats, and the two ends of each sleeper are slidably connected into the corresponding sliding grooves. The bottom of the sleeper is fixedly connected with a plurality of first springs, the lower ends of the first springs are fixedly connected with a pressing plate, the two ends of the upper side of the pressing plate are provided with first inclined faces, the two ends of the bottom of the sleeper are provided with second inclined faces respectively, and trapezoid blocks are embedded between the first inclined faces and the second inclined faces. The driving gear rotates to enable the two trapezoidal blocks to be far away from each other, and the pressing plate is lifted under the action of the dovetail groove and the dovetail block, so that the buffer cushion can be dismounted and replaced without completely dismounting the sleeper, and the maintenance efficiency is improved.
本发明公开了一种铁路高架桥梁轨道减震装置，包括铁路道轨和枕木，铁路道轨与枕木之间装有缓冲垫，每个枕木两端设置限位座，限位座固定连接在铁路道轨上侧，两个限位座相对的一侧均设置滑槽，枕木两端滑动连接在对应的滑槽内，枕木两端的底部分别装有支撑弹簧，支撑弹簧下压与滑槽底部固定连接，枕木底部固定连接多个第一弹簧，第一弹簧下端固定连接压板，压板上侧两端设有第一斜面，枕木底部两端分别设置第二斜面，第一斜面与第二斜面之间嵌入梯形块。本发明通过驱动齿轮转动使得两个梯形块相互远离，由于燕尾槽与燕尾块的作用，将压板抬升，使得不需要将枕木完全拆下即可对缓冲垫进行拆除更换，提高维护效率。
