在图形泵房中,梁式环行起重机越来越多地得到采用。梁式环行起重机的电源引入形式目前绝大多数引用一般梁式起重机上的平面集电器,即沿泵房内壁圆周敷设滑触线。也有的沿泵房内壁圆周悬挂移动电缆。这些电源引入形式在安装,运行及检修方面尚存在某些不足之处,这里介绍一种单梁环行起重机上使用的 Beam cranes are increasingly being used in graphic pumping stations. At present, most of the power sources introduced by beam cranes refer to the planar current collectors on general beam cranes, that is, the trolley lines are laid along the circumference of the pump house inner wall. Some also hanging mobile cable around the wall of the pump room. There are some shortcomings in the installation, operation and maintenance of these power introduction forms. Here we introduce a single-girder circular crane
