Description
本实用新型涉及轨道交通领域，适用于道床减振吸能技术的一种装置，具体涉及一种用于浮置道床板的钢弹簧隔振器预埋外筒。
如何解决轨道交通中振动和噪声对环境的破坏和居民生活的影响,成为人们关注地铁建设的焦点,也成为城市轨道交通建设能否可持续发展的关键之一。传统减振技术在减振降噪方面因减振效果有限,列车运行经过时产生的振动和噪声仍会直接影响到人们的生活和健康,对周围环境在一定程度上也造成了不良影响,因此在减振要求高的特殊地段传统减振技术显然已不再适用。钢弹簧浮置板减振技术应运而生，钢弹簧浮置板减振是将具有一定质量和刚度的混凝土道床板浮置于钢弹簧隔振器上，距离基底一定的位移空间,构成质量-弹簧-隔振系统。钢弹簧浮置板轨道结构是一种新型的特殊减振道床形式，由浮置板、钢弹簧隔振器、剪力铰、钢轨与扣件等组成，其核心技术为钢弹簧隔振器和浮置板的设计制造，钢弹簧隔振器目前国内已经有较多厂家能生产设计，结构形式也趋于雷同，所不同的是与隔振器相配套使用预埋在混凝土道床板中的预埋外筒由于制造工艺及使用要求的不同有不同的形式结构，有整体铸造成型的，有卷板成型的，有螺旋限位的，也有凸台限位的，根据不同的制造工艺和设计结构，成本和制造难度各不相同，在实际使用场合也有不同的效果。
本实用新型的设计目的也是为了找到一种新的制造和使用方式，通过改变现有的结构形式，同时保证原有钢弹簧隔振器的互换性要求，新的结构形式在在制作工艺及使用方式上与原有的外筒有所区别，能在一定程度上提高制造和使用效率。
