The invention belongs to the technical field of overhead working trucks, and particularly discloses a double-oil-cylinder telescopic boom for an overhead working truck and the overhead working truck. The double-oil-cylinder telescopic boom for the high-altitude operation vehicle is applied to the high-altitude operation vehicle, the first-stage oil cylinder and the second-stage oil cylinder can independently control and drive the front several stages of boom bodies and the rear several stages of boom bodies to synchronously stretch and retract, and the stretching and retracting efficiency of the boom bodies with the large number of stages is high; a first extending chain and a first retracting chain are arranged on the front several stages of arm frames with larger cross section areas, and only a second chain for extending transmission between adjacent arm frames is reserved on the subsequent stages of arm frames with smaller cross section areas, and a chain for retracting transmission between adjacent arm frames of the overhead working truck is omitted. Therefore, the arrangement of the chains between the adjacent arm frames is simplified, the sectional area of the arm frame is reduced, the compact design of the arm frame is realized, the assembly of the arm frame is also facilitated, and the assembly efficiency of the arm frame is improved.

    本发明属于高空作业车技术领域,具体公开了一种高空作业车用双油缸伸缩臂架及高空作业车。本发明的高空作业车用双油缸伸缩臂架,将其应用于高空作业车,一级油缸和二级油缸可以单独控制驱动前几级臂架和后几级臂架的同步伸、缩,对于级数较多的臂架,伸、缩效率较高;在前几级截面面积较大的臂架布置第一伸出链条和第一缩回链条,而在后续各级截面面积较小的臂架,只保留相邻近臂架之间用于伸出传动的第二链条,而省略高空作业车相邻近臂架之间用于缩回传动的链条。如此,以简化相邻近臂架之间链条的布置,并减小臂架的截面积,实现臂架的紧凑化设计,也便于臂架的装配,提高臂架的装配效率。
