The present disclosure relates to a telescopic working arm. The telescopic working arm comprises a multi-stage telescopic arm capable of stretching and retracting in the length direction of the multi-stage telescopic arm and a pipeline conveying system arranged in the multi-stage telescopic arm, wherein the multi-stage telescopic arm comprises a first-stage arm segment, a tail-stage arm segment and a plurality of intermediate-stage arm segments located between the first-stage arm segment and the tail-stage arm segment; the pipeline conveying system is used for conveying a power pipeline and asignal line from the tail end of the working arm to the front end of the working arm; the pipeline conveying system comprises a second pipeline box, a first pipeline box, a guide box component, a second drag chain and a first drag chain; and the second pipeline box and the first pipeline box are arranged on the first-stage arm segment and the tail-stage arm segment respectively, the guide box component is arranged in one of the intermediate-stage arm segments, the second drag chain is connected between the second pipeline box and the guide box component, and the first drag chain is connected between the first pipeline box and the guide box component. The working arm can reduce the peripheral space occupied by the pipeline conveying system, facilitate the arrangement of other related components, reduce the overall weight of the pipeline conveying system and a supporting structure thereof and improve the reliability and safety of the pipeline conveying system.

    本公开涉及一种伸缩式工作臂,包括:多级伸缩臂,能够沿自身长度方向伸缩,包括首级臂节、尾级臂节和位于首级臂节和尾级臂节之间的多个中间级臂节;以及管线输送系统,内置于多级伸缩臂,用于从工作臂的尾端向工作臂的首端输送动力管路及信号线路;其中,管线输送系统包括:分别设置于首级臂节、尾级臂节的第二管线盒和第一管线盒、设置于多个中间级臂节之一的导向盒组件、连接于第二管线盒与导向盒组件之间的第二拖链、和连接于第一管线盒与导向盒组件之间的第一拖链。本公开能够减少管线输送系统所占用的外围空间,方便其他相关部件的布置,降低管线输送系统及其支撑结构的总体重量,并提高管线输送系统的可靠性与安全性。
