The invention provides a folding arm type cantilever crane with a cylindrical articulated arm. Comprising a stand column, a joint arm positioning seat, a cylindrical joint arm, an arm end support and a chain block. A knuckle arm positioning seat is arranged on the upper portion of the stand column, cylindrical knuckle arms with gradually-decreased heights are sequentially assembled on the knuckle arm positioning seat, the adjacent cylindrical knuckle arms are connected through an upper pin shaft and a lower pin shaft to form a folding arm type cantilever, an arm end support is assembled on the cylindrical knuckle arm at the tail end, and a chain block is installed on the arm end support. The cylindrical articulated arm comprises a circular tube, an upper pin hinged support, a lower pin hinged support and a safety pin; the upper end of the circular tube is in interference fit with the upper pin hinged support, the lower end of the circular tube is in interference fit with the lower pin hinged support, and the circular tube, the upper pin hinged support and the lower pin hinged support are assembled to form an integrated structure; and meanwhile, safety pins are arranged at the joints of the circular tube and the upper pin hinged support and the circular tube and the lower pin hinged support. When the joint arm breaks down, the joint arm can be continuously used only by dismantling the joint arm and installing the standby shaft sleeve and the lengthened lower pin shaft. The cantilever crane is suitable for being used.
本发明提出的是一种圆柱形关节臂折臂式悬臂起重机。包括立柱、关节臂定位座、圆柱形关节臂、臂端支架和手拉葫芦;在立柱上部设置有关节臂定位座,依次装配高度递减的圆柱形关节臂,相邻圆柱形关节臂之间分别采用上销轴、下销轴连接形成折臂式悬臂,末端圆柱形关节臂装配有臂端支架,臂端支架上安装有手拉葫芦。圆柱形关节臂包括圆管、上销铰座、下销铰座和安全销;圆管上端与上销铰座过盈配合,圆管下端与下销铰座过盈配合,圆管、上销铰座、下销铰座之间装配形成一体式结构;同时在圆管与上销铰座、圆管与下销铰座连接处均安装安全销。关节臂发生故障,只需将其拆除,安装备用轴套及加长的下销轴,即可继续使用。适宜作为悬臂起重机应用。
