Dual-rigidity damping vibration isolator, floating slab with same and floating slab track system
The invention discloses a double-rigidity damping vibration isolator, a floating slab with the double-rigidity damping vibration isolator and a floating slab track system. The double-rigidity damping vibration isolator comprises a fixing part, and the fixing part comprises a base, a damping cylinder and a sleeve; the damping cylinder is fixed in the middle of the base; the sleeve is correspondingly positioned outside the damping cylinder and is fixed along the peripheral side of the base; a moving part comprises a top cover, a first-stage steel spring, a second-stage steel spring and a damping piston; the top cover is positioned above the sleeve and is movably connected with the upper end of the sleeve through a sealing piece in a sealing manner; the first-stage steel spring is sleeved between the damping cylinder and the sleeve, and the upper end and the lower end of the first-stage steel spring abut against the end faces of the top cover and the base respectively. The second-stage steel spring is arranged in the first-stage steel spring in a penetrating mode, one end of the second-stage steel spring abuts against the step end face of the step-shaped damping cylinder, and a distance is formed between the other end of the second-stage steel spring and the top cover; one end of the damping piston is fixed with the top cover, and the other end is positioned in the smaller-diameter section of the damping cylinder; and the damping cylinder and the sleeve are filled with damping liquid. The structure is simple, and environmental noise can be reduced.
本发明公开了一种双刚度阻尼隔振器及具有其的浮置板及浮置板轨道系统，双刚度阻尼隔振器包括固定部，固定部包括底座、阻尼筒及套筒；阻尼筒固定在底座中部；套筒对应位于阻尼筒外侧且沿底座周侧固定；运动部包括顶盖、一级钢弹簧、二级钢弹簧及阻尼活塞，顶盖位于套筒上方且与套筒上端通过密封件密封活动连接；一级钢弹簧套设在阻尼筒与套筒之间且其上下端分别与顶盖及底座的端面抵接；二级钢弹簧穿设在一级钢弹簧内部，且一端端部抵接在阶梯状阻尼筒的阶梯端面上，另一端与顶盖具有间距；阻尼活塞一端与顶盖固定，另一端位于阻尼筒筒径较小段内；阻尼筒及套筒内均装有阻尼液。本发明结构简单，可降低环境噪声。
