The ladder assembly of the aerial work platform comprises a large arm, a small arm is movably arranged at the upper end of the large arm through a rotating shaft, a first fixing block is fixedly arranged at the lower end of the outer side surface of the large arm, a first hydraulic cylinder is movably arranged in the first fixing block through a rotating shaft, and a second fixing block is fixedly arranged on one side of the lower end of the small arm. And the shaft end of a telescopic rod of the first hydraulic cylinder is movably connected with the second fixing block through a rotating shaft, an operation platform body is fixedly arranged at the end, away from the large arm, of the small arm, and an expansion mechanism is arranged between the operation platform body and the small arm. The working platform is good in use effect, the overall range of the working platform body can be automatically increased and expanded through the expansion mechanism when needed, construction workers can work conveniently, meanwhile, the working platform can be rapidly contracted and folded, and inconvenience caused by large occupied space during transportation can be prevented.
本发明公开了一种高空作业平台的梯架,包括大臂,所述大臂上端通过转轴活动设置有小臂,所述大臂外侧表面下端固定设置有第一固定块,所述第一固定块内部通过转轴活动设置有第一液压缸,所述小臂下端一侧固定设置有第二固定块,所述第一液压缸的伸缩杆轴端通过转轴与第二固定块之间活动连接,所述小臂远离大臂的一端固定设置有作业平台本体,所述作业平台本体与小臂之间设置有扩展机构。本发明使用效果好,通过扩展机构可以在需要时自动增加扩大作业平台本体的整体范围,从而可以方便施工人员进行工人,同时还可以快速收缩折叠起来,从而可以防止运输时占用空间较大不方便。
