The invention relates to the technical field of operation machines, and provides a telescopic boom and an operation machine. The telescopic boom comprises at least two boom sections which are sequentially sleeved from inside to outside, and any two adjacent boom sections are connected in a sliding mode. The at least two guide structures are arranged on the corresponding arm sections respectively, the guide structures extend in the length direction of the arm sections, and parts of the two guide structures corresponding to any two adjacent arm sections are overlapped; the sliding assemblies are arranged on the guide structures, can move between any two adjacent guide structures and are used for hoisting the working buckets; the first driving mechanism is used for driving the sliding assembly to move. After positioning of the telescopic boom is completed, under the conditions that the number of to-be-rescued workers is large and repeated transportation rescue is needed, only the working bucket needs to move back and forth along the boom section, repeated stretching, lifting and positioning of the telescopic boom are not needed, the operation process of the telescopic boom is simplified, the time of repeated adjusting and positioning of the telescopic boom is saved, and the working efficiency is improved. And the rescue efficiency can be effectively improved.
本发明涉及作业机械技术领域,提供一种伸缩臂架及作业机械。伸缩臂架包括:至少两个由内向外依次套装的臂节,任意相邻的两个臂节滑动连接;至少两个导向结构,分别设置在对应的臂节,导向结构沿臂节的长度方向延伸,任意相邻的两个臂节所对应的两个导向结构的部分重叠;滑动组件,设置于导向结构并可在任意相邻导向结构之间移动,滑动组件用于吊装工作斗;第一驱动机构,用于驱动滑动组件移动。伸缩臂架定位完毕后,在待救援人员较多,需要多次运输救援的情况,只需使工作斗沿臂节往复移动即可,无需对伸缩臂架进行重复的伸缩、升降和定位,简化了伸缩臂架的操作过程,节省了伸缩臂架多次调整定位的时间,能够有效地提高救援效率。
