现代有轨电车轨道用道口扣件罩的研发

Research and Development of Rail Fastener Cover at Grade Crossing of Modern Tram

针对现代有轨电车一般路段使用的扣件罩在平交道口铺设时易破坏、造成路面损坏的情况,研发了专用道口扣件罩。介绍和分析了该道口扣件罩采用高强度玻璃钢材质制作,具有耐碾压、不易变形、绝缘性能好等特点。经室内试验和批量应用,可以确保道口路面的运行情况良好,解决了现代有轨电车线路建设中的关键难题,具有良好的示范效果。

The fastener cover used in the general section of modern tram is easy to be damaged at grade crossing,which results in the road pavement damage.So a special rail fastener cover is developed to use at grade crossing,which is made of high strength glass fiber reinforced plastic.The special rail fastener cover is featured with rolling resistance,deformation resistance and good insulation performance.The indoor test and batch application prove that this special cover can ensure the good road operation at grade crossing,and solve the key problem in the construction of modern tram lines.
