The invention discloses a pipe lifting assembly and a telescopic lifting arm, the pipe lifting assembly comprises multiple stages of pipes which are sequentially nested in a sliding mode, and the multiple stages of pipes comprise a first-stage pipe, one or more middle pipes and a last-stage pipe; a guide rib and a guide groove which are matched with each other are arranged between at least one pair of adjacent pipes, and a friction block with damping is arranged between at least one pair of adjacent pipes. And by arranging the guide ribs and the guide grooves, the relative displacement between the adjacent pipes in the circumferential direction is avoided. And by arranging the friction blocks with damping, stable friction force between the adjacent pipes is kept, and stable lifting can be provided.
本发明公开了一种管提升组件和伸缩升降臂,其中管提升组件包括:依次滑动嵌套的多级管,所述多级管包括一级管、一个或多个中间管和末级管;至少一对相邻的管之间设置有相互配合的导向筋条和导向槽,至少一对相邻的管之间设置有带阻尼的摩擦块。通过设置导向筋条和导向槽,避免相邻管之间的圆周方向的相对位移。通过设置带阻尼的摩擦块,保持相邻管之间具有稳定的摩擦力,能够提供稳定的提升。
