Sleeved profile steel spring vibration isolator, roadbed slab and roadbed
The invention provides a sleeved profile steel spring vibration isolator, a roadbed slab and a roadbed, the sleeved profile steel spring vibration isolator comprises an outer sleeve, an elastic unit, a locking gasket and a height adjusting gasket, and the roadbed slab is loaded on a base through a plurality of sleeved profile steel spring vibration isolators, so that rigid connection between the roadbed and a base structure can be cut off, and vibration and noise reduction is realized. The elastic unit comprises a shell, a supporting spring arranged in the shell and an inner spring assembly nested in an inner ring of the supporting spring, and after the supporting spring and the inner spring assembly are combined in a sleeved mode, a larger comprehensive elastic coefficient can be formed in unit space, so that the bearing capacity of the sleeved section steel spring vibration isolator is higher. Particularly, the inner spring assembly comprises a plurality of inner springs which are arranged in series and are steel springs, so that the vibration isolators with different elastic rigidities and bearing capacities can be obtained only by increasing or decreasing the number of the inner springs, adjustment can be conveniently carried out, and more ideal vibration reduction and noise reduction effects can be achieved.
本发明提供一种套设型钢弹簧隔振器、道床板以及道床，包括外套筒、弹性单元以及锁紧垫片、调高垫片，道床板通过多个套设型钢弹簧隔振器载置在基底上，因此能够隔断道床和基底结构之间的刚性连接，实现减振降噪。弹性单元包括壳体、设置在壳体内的支撑弹簧、以及嵌套在支撑弹簧内圈的内弹簧组件，支撑弹簧和内弹簧组件套设组合后，可以在单位空间内形成更大的综合弹性系数，使得套设型钢弹簧隔振器的承载力更强。特别是，内弹簧组件包含多个串联设置的内弹簧，其均为钢弹簧，因此只通过增减内弹簧数量，就能够得到具有不同弹性刚度和承载能力的隔振器，从而可方便地进行调整，以实现更为理想的减振和降噪效果。
