The invention provides a telescopic folding arm support which comprises a support body, a supporting ring is fixedly connected to the surface of the support body, a rotating motor is arranged in the support body, and the output end of the rotating motor is connected to a rotating disc through a coupler. According to the telescopic folding type cantilever crane and the overhead working truck adopting the telescopic folding type cantilever crane, the rotating motor is started to drive the rotating rod to rotate towards one side, so that the rotating rod moves towards one side in the rotating block, and the mounting box drives the operation table to move left and right; and meanwhile, a rotating motor can be matched with a rotating disc, so that a rotating block drives a mounting box to rotate towards one side, and the operating table rotates from the longitudinal direction to the transverse direction, so that the operating table can work in the middle of a narrower space, and meanwhile, the working efficiency is improved. And the operation table can be conveniently rotated to the position needing to be maintained for maintenance.
本发明提供一种伸缩折叠式臂架,包括:架体,架体的表面固定连接有支撑环,转动电机设置于架体的内部,转动电机的输出端通过联轴器连接于转动盘。本发明提供一种伸缩折叠式臂架及采用该结构的高空作业车,通过启动旋转电机后带动着转动杆向一侧进行转动,使转动杆在转动块的内部向一侧进行移动,使安装盒带动着操作台进行左右位置的移动,从而方便快速的将操作台调节到合适的位置进行使用,同时可以通过转动电机配合转动盘,使转动块带动着安装盒向一侧进行转动,使操作台从纵向转动到横向,从而使操作台可以在更狭小的空间中间进行作业的同时,也方便将操作台转动到与面向需要维修的位置进行维修。
