钢轨伸缩调节器是高速铁路重要的轨道部件之一,可协调长大桥梁因梁体温差引起的梁端伸缩位移和长钢轨的伸缩位移,使桥上无缝线路在运营过程中释放钢轨温度力,从而减小轨道及桥梁所承受的无缝线路纵向力。本文以西宝客运专线咸阳渭河特大桥钢轨伸缩调节器为研究对象,通过轨道状态监测并结合养护维修情况分析其运营状态。将运营期间存在的病害情况进行了系统的归纳,分析了病害原因,总结了现阶段采取的整治措施,并针对该桥上钢轨伸缩调节器养护维修给出了建议。
Rail retractable regulator is one of the important track components of the high-speed railway. It can coordinate the telescopic displacement of the beam ends caused by the difference in body temperature between the long and large bridges and the telescopic displacement of the long rails, so that the seamless rails on the bridge release the rail temperature during operation So as to reduce the longitudinal force of the seamless line borne on the track and the bridge. In this paper, the Xi-Bao passenger dedicated Xianyang Weihe River Bridge extension telescopic regulator as the research object, through the track condition monitoring and maintenance and repair situation analysis of its operating status. The disease conditions during the operation were systematically summarized, the causes of the diseases were analyzed, and the rectification measures adopted at the present stage were summarized. Suggestions were given for the maintenance and repair of the rail expansion and contraction regulator on the bridge.
