一种新型碗臂偏移测量仪在哈大客运专线的应用

Application of New Cantilever Off-Setting Measuring Instrument on Harbin-Dalian Passenger Dedicated Line

针对客运专线施工当中无法一次性将碗臂偏移和吊弦安装到位,造成导高超标,增加接触网精调过程当中的工作量。设计了一种新型的碗臂偏移测量仪,该仪器能够准确的测量碗臂偏移量和吊弦位置,确保了哈大客运专线接触网的施工质量,而且在哈大客运专线长春—哈尔滨段得到了广泛的应用。

A new cantilever displacement measuring meter has been developed to solve the problem that the off-setting of cantilevers and installation of dropper can hardly be completed by one time,which results in unacceptable conductor height and excessive work for fine adjustment of catenary.The new instrument can measure accurately the off-setting of cantilever and the position of dropper to have guaranteed the quality of catenary erection,and found extensive application on Changchun^Harbin section on Harbin-Dalian Passenger Dedicated Line.
