The invention relates to a lifting cantilever device of an electrified railway mobile overhead line system, the mobile overhead line system and an operation method. The lifting cantilever device is applied to the field of mobile overhead line systems, the lifting cantilever device at least comprises more than one stage of liftable stand column and a cantilever supporting structure, and further comprises a carrier cable and/or a contact line; the cantilever supporting structure is directly or indirectly arranged on the liftable stand column, and the carrier cable and/or the contact line are/is directly or indirectly arranged on the cantilever supporting structure. More than one stage of liftable stand column can extend or retract to drive the carrier cable and/or the contact line to ascend or descend. When the gantry crane hoists goods, especially when the mobile overhead line system moves to a non-working position and is close to a train carriage, the goods or loading and unloading tools can be effectively prevented from colliding with the carrier cable and/or the contact line, and safety guarantee is provided for goods loading and unloading.
本发明涉及一种电气化铁路移动接触网升降腕臂装置、移动接触网及操作方法,所述升降腕臂装置应用于移动接触网领域,所述升降腕臂装置至少包括一级以上的可升降立柱和腕臂支持结构,还包括承力索和/或接触线;所述腕臂支持结构直接或者间接的设置在可升降立柱上,所述承力索和/或接触线直接或者间接的设置在所述所述腕臂支持结构上;一级以上的可升降立柱能够在伸出或者缩回带动承力索和/或接触线升高或者降低。在龙门吊吊装货物的时候,特别是移动接触网移动到非工作位,离火车车厢比较近的时候,可以有效的避免货物或者装卸工具碰撞到承力索和/或接触线,为货物装卸提供了安全保障。
