Steel spring vibration isolator
The invention provides a steel spring vibration isolator. The steel spring vibration isolator comprises an embedded outer sleeve, an elastic element, a height adjusting gasket, a locking gasket and a spring breaking indicator. Wherein the elastic element comprises two steel springs which are different in diameter and are of a nested structure, so that when one steel spring breaks and loses efficacy, the other steel spring can still play a certain supporting role, certain system redundancy is provided, and the safety of the track is improved; due to the arrangement, the flexibility is also improved, for example, one steel spring can be used as a standard part with fixed rigidity, and the other steel spring can be adjusted according to actual requirements, so that the overall rigidity of the elastic element can be adjusted. The spring breaking indicator is arranged above the elastic element, and the indicating end of the spring breaking indicator is located at the upper end opening of the outer sleeve, so that the state of the steel spring can be conveniently observed, and the fracture failure condition can be found in time. The elastic element can be assembled in advance, the elastic element only needs to be installed as a whole during construction, and construction is more convenient and efficient.
本发明提供一种钢弹簧隔振器，包括预埋外套筒、弹性元件、调高垫片、锁紧垫片和断簧指示器。其中弹性元件包含有两个直径不同、呈嵌套结构的钢弹簧，因此在其中一个钢弹簧断裂失效时，另一个钢弹簧仍可起到一定支撑作用，提供了一定的系统冗余，提高了轨道的安全性；这样的设置也增加了灵活性，例如可将其中一个钢弹簧作为具有固定刚度的标准件，另一个钢弹簧则根据实际需要进行调节，从而能够调节弹性元件整体的刚度。断簧指示器设置在弹性元件上方且其指示端位于外套筒的上端开口处，因此能够方便地观察钢弹簧的状态，及时发现断裂失效情况。弹性元件可预先装配，在施工时弹性元件仅需作为一个整体进行安装，施工更为方便高效。
