The invention discloses an electric multifunctional operation vehicle with a folding arm crane. The folding arm crane is fixedly arranged on a chassis girder between a vehicle head and a multifunctional operation compartment; the folding arm crane comprises a bearing base, a slewing bearing, a large arm, a middle arm, a telescopic arm, a large arm oil cylinder, a rotation detection assembly and a control assembly, the bearing base is fixedly arranged on the chassis girder, the large arm is rotationally connected with the top of the bearing base through the slewing bearing, the large arm, the middle arm and the telescopic arm are sequentially connected, and the two ends of the large arm oil cylinder are connected with the large arm and the middle arm respectively; the control assembly is electrically connected with the slewing bearing and the big arm oil cylinder, and drives the folding arm crane to rotate in the horizontal direction and the vertical direction through the slewing bearing and the big arm oil cylinder; the control assembly is further electrically connected with the rotation detection assembly, the telescopic length of the large arm oil cylinder is obtained through the rotation detection assembly, and when the telescopic length is within the safe telescopic range, the slewing bearing is controlled to rotate normally to drive the folding arm crane to act so as to avoid the vehicle head and the multifunctional operation compartment.

    本发明公开了一种含折臂吊的电力多功能作业车,包括:折臂吊固设于车头和多功能作业厢之间的底盘大梁上;折臂吊包括:承重底座、回转支承、大臂、中间臂、伸缩臂、大臂油缸、转动检测组件和控制组件,承重底座固设于底盘大梁上,大臂通过回转支承与承重底座顶部转动连接,大臂、中间臂和伸缩臂依次连接,大臂油缸两端分别与大臂和中间臂连接;控制组件与回转支承和大臂油缸电连接,通过回转支承和大臂油缸带动折臂吊沿水平方向和竖直方向转动;控制组件还与转动检测组件电连接,通过转动检测组件获取大臂油缸的伸缩长度,当伸缩长度位于安全伸缩范围时,控制回转支承正常转动带动所述折臂吊动作,以规避车头和多功能作业厢。
