Vibration and noise reduction device for subway upper cover
The invention discloses a vibration and noise reduction device for an upper cover of a subway, belongs to the technical field of vibration and noise reduction devices, and provides the following scheme that the vibration and noise reduction device comprises a plurality of mounting bases which are detachably mounted on a rail body; the core of the device is that a precisely-designed buffering and damping structure forms a remarkable damping effect in a closed system, vibration energy is effectively absorbed and dissipated, meanwhile, along with movement of damping liquid, a first movable block is subjected to corresponding counter-acting force, then high-pressure nitrogen pre-filled in a third cavity is compressed, the high-pressure nitrogen serves as an elastic medium, and the damping effect is greatly improved. The response speed of the vibration reduction system is increased, vibration impact is further buffered through compressibility of the vibration reduction system, the multi-stage vibration reduction effect is achieved, vibration and noise generated during subway operation are remarkably reduced through the comprehensive action mechanism, a more quiet and comfortable space is provided for the surrounding environment, construction is convenient and fast, the construction period is shortened, the construction cost is reduced, and the construction efficiency is improved. And convenient conditions are provided for rapid upgrading and reconstruction of a subway system.
本发明公开了一种地铁上盖减振降噪装置，属于减振降噪装置技术领域，现提出如下方案，其包括若干个与铁轨本体可拆卸安装的安装基座；其核心在于精密设计的缓冲减振结构，在封闭系统内形成显著的阻尼效应，有效吸收并耗散振动能量，同时，随着阻尼液的移动，第一活动块受到相应的反作用力，进而对第三空腔内预充的高压氮气进行压缩，高压氮气作为弹性介质，不仅增强了减振系统的响应速度，还通过其可压缩性进一步缓冲了振动冲击，形成了多级减振效果，这一综合作用机制显著降低了地铁运行时产生的振动与噪音，为周边环境提供了更加宁静舒适的空间，且施工便捷，减少了施工周期和成本，为地铁系统的快速升级与改造提供了便利条件。
