Description

铁道混凝土弹性轨枕枕下用橡胶垫板
所属领域
本实用新型涉及一种橡胶垫板,特别是一种铁道混凝土弹性轨枕枕下用橡胶垫板。
背景技术
有渣轨道在长期的高速列车载荷反复作用下已达到承载能力的极限,表现在碎石道床的破坏不断加剧,可用的维修时间越来越少,靠低刚度轨下胶垫来缓和高速轮轨动力冲击作用是远远不够的。
发明内容
本发明的目的即在于克服现有技术的缺点,提供一种铁道混凝土弹性轨枕枕下用橡胶垫板,它能降低轨道刚度,提高轨道弹性,减少维修量和费用。
本发明的目的通过以下技术方案来实现:铁道混凝土弹性轨枕枕下用橡胶垫板,垫板分顶面和底面,垫板顶面上分布有平行纵向沟槽,底面分布有圆弧形凹槽。平行纵向沟槽深4--8mm,平行纵向沟槽之间的距离为10-20mm,垫板四周倒角100--150°。圆弧形凹槽之间的距离为120--180mm。垫板厚度为12--18mm。
通过上面的叙述可以看出,本实用新型具有以下优点:铁道混凝土弹性轨枕枕下用橡胶垫板,它能缓和列车冲击作用,减轻道床振动,减少道渣粉化,减轻养路工作量和降低轨道振动、噪声等。
附图说明
图1为本实用新型俯视图
图2为本实用新型剖面图
具体实施方式
下面结合附图对本实用新型做进一步的描述
如图1所示,铁道混凝土弹性轨枕枕下用橡胶垫板,垫板分顶面1和底面2,垫板顶面1上分布有平行纵向沟槽3,底面2分布有圆弧形凹槽4,如图2所示。平行纵向沟槽3深4--8mm,以6mm为最佳,平行纵向沟槽3之间的距离为10-20mm,以16mm为最佳,垫板四周倒角100--150°,以120°为最佳。圆弧形凹槽4之间的距离为120--180mm,以150mm为最佳,垫板厚度为12--25mm,以15mm为最佳。
