编组站使用绳索牵引推送小车轨道钢轨受力的研究

Analysis about the Forces acted on the in Classification Yard by the Cable Propelling Trolley

徐州北站是目前国内唯一采用液压绳索牵引推送小车调车设备的编组站 ,自小车使用以来 ,收到了良好的经济效益 .但是目前国内外还没有文献报道有关绳索牵引推送小车对钢轨受力影响的研究 .本文从现场试验、实验室静态测试、疲劳试验及理论计算 ,对此问题作了详细的研究 .并得出了在目前的运营条件下 。

North Xuzhou Classification Yard is only one of using the cable propelling trolley in China. The economic beneficial result has been gotten greatly since the trolley has been used. But until now, there are not any papers in the science journals at both home and abroad to describe the trolley how to affect the forces acted on the rail in the classification yard. According to field test, the static stress and fatigue test in the laboratory and theoretical calculation, this paper analyzes the stress level in the rail in detail. At least, this paper puts forward that the track using the cable propelling trolley in Classification Yard can be serviced in safety.
