The invention provides a telescopic folding type arm frame and an overhead working truck, and relates to the technical field of overhead working trucks. According to the telescopic folding arm frame, the arm frame I of the main telescopic arm frame is driven by the main driving mechanism to relatively stretch out or retract, so that the height of the main body part of the arm frame is adjusted; the first folding driving mechanism drives the expansion telescopic boom to swing relative to the main telescopic boom, so that the angle of the tail end part of the boom relative to the main body part of the boom is adjusted; the extension driving mechanism drives the arm frame II of the extension telescopic arm frame to relatively extend or retract, so that the length of the tail end part of the arm frame is adjusted; the second folding driving mechanism drives the platform base to swing relative to the extension telescopic boom, so that the angle of the tail end of the boom relative to the tail end part of the boom is adjusted; the rotary driver drives the mounting seat to rotate so as to adjust the horizontal rotating angle of the working platform; therefore, the angle position of the front end of the boom can be flexibly adjusted, and the overhead working truck can be applied to more working conditions.
本发明提供了一种伸缩折叠式臂架及高空作业车,涉及高空作业车技术领域。本发明的伸缩折叠式臂架,由主驱动机构驱动主伸缩臂架的臂架Ⅰ相对伸出或者缩回,以实现臂架主体部分高度的调节;由第一折叠驱动机构驱动扩展伸缩臂架相对于主伸缩臂架摆动,以实现臂架末端部分相对于臂架主体部分角度的调节;由扩展驱动机构驱动扩展伸缩臂架的臂架Ⅱ相对伸出或者缩回,以实现臂架末端部分长度的调节;由第二折叠驱动机构驱动平台座相对于扩展伸缩臂架摆动,以实现臂架最末端相对于臂架末端部分角度的调节;由回转驱动器带动安装座转动,以实现工作平台的水平转动角度的调节;如此,以实现臂架前端角度位置灵活调节,使高空作业车应用更多工况。
