Locking, limiting and damping type spring vibration isolator suitable for floating slab ballast bed
The invention discloses a locking, limiting and damping type spring vibration isolator suitable for a floating slab ballast bed, which comprises an upper support, a lower support and a plurality of springs, the plurality of springs are distributed between the upper support and the lower support in an array mode, and the spring vibration isolator further comprises a movable adjusting type limiting component and a damping component. On one hand, pre-tightening compression treatment can be achieved, multiple leveling operations are not needed before installation, on-site assembly is facilitated, meanwhile, displacement of the upper support and the lower support can be avoided through distribution of locking points, and then shaking of the spring in the horizontal direction is limited; on the other hand, viscous motion is formed in the damping filler to absorb vibration energy of the springs in the horizontal direction and provide spring motion buffering, so that stable transition connection of the two floating slabs is achieved, complete and sequential connection of the floating slab ballast bed is facilitated, line operation is relatively smooth and safe, the comfort level of passengers is enhanced, and in addition, the structure is simple, maintenance is convenient, and cost is low. And the probability of the corrugation phenomenon of the steel rail is greatly reduced.
本发明公开了适用于浮置板道床的锁紧、限位、阻尼式弹簧隔振器，其包括上支座、下支座、弹簧，多个所述弹簧呈阵列式分布在上支座和下支座之间，弹簧隔振器还包括活动调节式限位部件和阻尼部件。本发明一方面能够预紧压缩处理，安装前无需多次调平操作，方便现场拼装，同时锁紧点的分布能够避免上下支座的移位，进而限制弹簧水平方向晃动；另一方面在阻尼填料形成粘滞运动，以吸收各弹簧水平方向振动能量和提供弹簧运动缓冲，因此，实现两块浮置板的平稳过渡连接，便于浮置板道床的完整顺接，而且线路运行相对的平顺和安全，增强乘客的舒适度，此外，结构简单，维护方便，也大幅度降低钢轨波磨现象发生的概率。
