The invention discloses a connecting frame, a boom system and an aerial work platform. The connecting frame comprises a frame body, a flange plate and a hinge seat, the frame body is a variable cross-section hollow column, the frame body is provided with a first hinge part used for being connected with a boom, the flange plate is installed at the end, with the large cross-section, of the frame body, and the hinge seat is fixedly connected to the end, with the small cross-section, of the frame body; the boom system comprises the connecting frame; and the aerial work platform is provided with the boom system. The frame body of the connecting frame is designed to be of the variable cross-section hollow column structure, the weight of the connecting frame is less than that of an existing connecting frame structure while the same operation height is met, and meanwhile the degree of freedom of movement at the joint of the boom is larger.
本发明公开了一种连接架、臂架系统及高空作业平台,连接架包括:架体、法兰板、铰接座,所述架体为变截面空心柱,所述架体上设有用于连接臂架的第一铰接部,所述法兰板安装在所述架体截面大的一端,所述铰接座固定连接在所述架体截面小的一端;臂架系统包括前述的连接架;高空作业平台设置有前述的臂架系统。本发明中连接架的架体设计为变截面空心柱结构,在满足相同作业高度的同时,比现有的连接架结构重量更轻,同时在臂架的连接处活动自由度更大。
