The invention provides a telescopic arm internal arrangement structure and a high-altitude operation device, and belongs to the technical field of engineering vehicles. The technical problems that in the telescopic process of the telescopic arm, a telescopic oil cylinder jumps, and a pipeline conveying device in an arm barrel is unreasonably arranged are solved. According to the technical scheme, the inner structure of the telescopic boom comprises a telescopic oil cylinder extending into a tail-section boom barrel, a cylinder rod of the telescopic oil cylinder is connected with the tail of a basic boom barrel, a cylinder barrel of the telescopic oil cylinder is connected with the tail of a second-section boom barrel, a first pipeline conveying device is arranged at the bottom of the basic boom barrel, and a supporting groove is formed in the bottom of the tail-section boom barrel; the invention has the following beneficial effects: the rectangular barrel arranged in the tail end arm barrel replaces a traditional supporting plate to a certain extent, and with the assistance of the rollers, the problem of jumping of the oil cylinder is solved, and meanwhile, the arrangement of a pipeline conveying device in the arm barrel is changed, so that the internal structure of the arm barrel is more reasonable.
本发明提供了一种伸缩臂内布置结构及高空作业装置,属于工程车辆技术领域。解决了伸缩臂在伸缩过程伸缩油缸产生跳动以及臂筒内部管线输送装置布置不合理的技术问题。其技术方案为:一种伸缩臂内结构,包括伸入到末节臂筒内部的伸缩油缸,伸缩油缸的缸杆与基本臂筒的尾部连接,伸缩油缸的缸筒与第二节臂筒的尾部连接,基本臂筒底部设置有第一管线输送装置,末节臂筒底部设置有托槽,托槽上端滑动设置有矩形筒,本发明的有益效果为:本发明在末端臂筒内部设置的矩形筒一定程度上代替了传统的托板,加上滚轮的辅助,解决了油缸跳动的问题,同时改变臂筒内部管线输送装置的布置,使臂筒内部结构更加合理。
