The invention provides an anchor rod telescopic arm and engineering machinery, and belongs to the technical field of engineering machinery. The first end of the arm frame is rotatably connected with the first rotating seat; the person standing platform is rotatably connected with the second end of the arm frame; one end of the first telescopic piece is connected with the first rotating seat, and the other end of the first telescopic piece is connected with the arm frame; one end of the second telescopic piece is connected with the arm frame, and the other end of the second telescopic piece is connected with the person standing platform; when the first telescopic piece extends, the second telescopic piece is shortened, and when the first telescopic piece is shortened, the second telescopic piece extends. According to the technical scheme, the person standing platform is arranged, so that a constructor can observe the drilling condition of the anchor rod more easily, and the person standing platform can be linked with the lifting action of the arm frame, so that the person standing platform is level with the ground.
本申请提出了一种锚杆伸缩臂和工程机械,属于工程机械技术领域,锚杆伸缩臂包括:第一转座;臂架,臂架的第一端与第一转座可转动地连接;站人平台,与臂架的第二端可转动地连接;第一伸缩件,第一伸缩件的一端与第一转座连接,第一伸缩件的另一端与臂架连接;第二伸缩件,第二伸缩件的一端与臂架连接,第二伸缩件另一端与站人平台连接;其中,第一伸缩件伸长时,第二伸缩件缩短,第一伸缩件缩短时,第二伸缩件伸长。通过本申请的技术方案,设置站人平台,使施工人员能够更容易观察锚杆的钻进情况,站人平台可以同臂架举升动作联动,使站人平台同地面水平。
