一种用于铁轨的防冻道砟减振垫

Anti-freezing railway ballast anti-vibration pad for rail

Abstract

The utility model relates to vibration isolation and reduction technology in the fields of urban rail transit, mechanical equipment support, house buildings and the like, in particular to an anti-freezing railway ballast anti-vibration pad for a rail. The anti-freezing railway ballast anti-vibration pad comprises a body (1), the body (1) comprises three rubber layers, a first fiber layer (4) and a second fiber layer (5) are respectively arranged among the three rubber layers, and a damping layer is arranged on the body (1) and comprises a plurality of three-square tables (2) which are arrayed on one side surface of the body (1). The anti-freezing railway ballast anti-vibration pad not only can function in isolating a vibration noise source of the rail, but also has fine compression resistance and vibration isolation performances, and gaps among the projecting three-square tables can achieve fine ventilation and drainage functions, so that depositions cannot be formed underground a cushion layer.
本实用新型涉及城市轨道交通、机械设备支撑、房屋建筑等领域中进行隔振减振的技术,尤其涉及一种用于铁轨的防冻道砟减振垫。其包括本体(1),本体(1)由三层橡胶层组成,三层橡胶层之间分别设有第一纤维层(4)、第二纤维层(5),本体(1)上设有阻尼层,阻尼层由多个三棱台(2)按阵列设置在本体(1)的一侧表面。本实用新型不仅能起到对轨道振动噪音源隔离作用,还具有良好的抗压和隔振性能,并且凸起三棱台间的空隙能起到良好的通风和排水作用,使垫层地下不会形成沉积。
