Combined steel spring vibration isolator, roadbed slab and roadbed
The invention provides a combined type steel spring vibration isolator, a roadbed slab and a roadbed, the combined type steel spring vibration isolator comprises an outer sleeve fixedly embedded in a slab body of the roadbed slab, an elastic unit arranged below the outer sleeve and a locking gasket embedded in the outer sleeve; the roadbed slab is loaded on the base through the combined steel spring vibration isolators, so that rigid connection between the roadbed structure and the base structure can be cut off, and the vibration reduction effect is achieved. Particularly, the elastic unit comprises a shell, two layers of spring assemblies and a linkage plate, the two layers of spring assemblies and the linkage plate are contained in the shell, and after the two layers of spring assemblies are combined, a larger comprehensive elastic coefficient can be formed in unit space, so that the application range of the vibration isolator is wider. Furthermore, at least one layer of the two layers of spring assemblies comprises a plurality of steel springs which are arranged in parallel, so that the required vibration reduction performance can be realized through combination and parallel connection of the steel springs of a plurality of standard parts, and the rigidity of the elastic unit and the performance of the vibration isolator are more convenient to adjust.
本发明提供一种组合型钢弹簧隔振器、道床板以及道床，该组合型钢弹簧隔振器包括固定嵌设在道床板的板体中的外套筒、设置在外套筒下方的弹性单元以及嵌合在外套筒中的锁紧垫片，道床板通过多个组合型钢弹簧隔振器载置在基底上，因此能够隔断道床结构和基底结构之间的刚性连接，实现减振效果。特别是，弹性单元包括壳体以及容纳在壳体内的两层弹簧组件、联动板，两层弹簧组件组合后，可在单位空间内形成更大的综合弹性系数，使得该隔振器的适用范围更广。进一步，两层弹簧组件中至少一层包含有多个并联设置的钢弹簧，因此可以通过多个标准件的钢弹簧的组合、并联实现需要的减振性能，弹性单元的刚度、隔振器性能的调整更为方便。
