The invention discloses a maintenance process for a trolley running track of an electric single-beam bridge crane, which comprises the following steps of: when the trolley running track is maintained, cutting a bent and deformed lower flange plate of the trolley running track to be maintained, and welding the lower flange plate and the lower flange plate; a new trolley running track is connected to the cutting face of the lower flange plate of the to-be-maintained trolley running track, maintenance work of the trolley running track is completed, the maintenance process does not need to be applied to steam hoisting equipment, and the problems that in a multi-layer plant of a chemical plant, many devices exist, and maintenance is complex can be solved. The problem that the maintenance cost is extremely high due to local bending deformation of the lower flange of the trolley running track of the electric single-beam crane in the prior art is solved, and meanwhile, a new trolley running track can be machined and assembled in advance, so that the maintenance efficiency of the trolley running track is improved, and the maintenance period is shortened.

    本发明公开了一种用于电动单梁桥式起重机小车运行轨道的维修工艺,在维修小车运行轨道时,通过将待维修小车运行轨道的已经发生弯曲变形的下翼缘板切割,然后通过焊接的方式,在待维修小车运行轨道下翼缘板的切割面上连接新小车运行轨道,完成小车运行轨道的维修工作,该维修工艺不需要运用到汽吊设备,能够解决化工厂多层厂房内及设备多,汽吊无法开进设备附近的电动单梁起重机小车运行轨道下翼缘发生局部弯曲变形进行维修成本极高的问题,同时新小车运行轨道可以进行预先加工组装,以提高了小车运行轨道的维修效率,缩短了维修周期。
