1 多功能防电拱架西安科研所机械研究室研制的“多功能防电拱架”能够在接触网不停电,列车正常运行条件下,进行悬臂式棚洞,盖板棚洞,拱式明洞的施工,同时还可用于跨线桥,跨线渡槽,隧道衬砌等多种工程的施工,并可作为非电化铁路移动式拱梁模使用。该设备已获国家专利。在宝成线218工点施工中,在全路首次用一套装置,在不停电条件下建 1 multi-functional anti-scaffolding Xi’an Research Institute of Machinery developed by the “multi-function anti-electric arch ” to be able to contact the network without power, the train under normal operating conditions, cantilevered shed, cover shed holes, arch Myeong-dong construction, but also can be used for overpass, cross-aqueduct, tunnel lining and other construction projects, and can be used as a non-electrochemical railway beam arch mode. The device has been national patent. In Baocheng line 218 construction site, the first time in the whole set with a device, under the conditions of uninterrupted power supply
