Telescopic mechanical arm of backhoe dredger
The invention relates to the technical field of dredger mechanical arms, and discloses a telescopic mechanical arm of a backhoe dredger, the telescopic mechanical arm comprises a suspension arm structure and a telescopic structure, the suspension arm structure comprises a main suspension arm, and a first hydraulic cylinder is fixedly mounted on one side of the top of the main suspension arm; and the telescopic structure comprises a connecting block, the connecting block is hinged to a telescopic rod of the first hydraulic cylinder, a connecting arm is fixedly installed on one side of the outer surface of the connecting block, and two supporting rods are fixedly installed at the top of the outer surface of the connecting arm. Through the arranged suspension arm structure and the telescopic structure, when the device works, a telescopic rod of a first hydraulic cylinder stretches out and draws back to control the working angle of a connecting arm, when the dredging range needs to be enlarged, a first servo motor is started to enable a threaded rod to rotate in the connecting arm, and due to limiting of the connecting arm and arrangement of the telescopic arm, the working angle of the connecting arm is controlled; the telescopic arm can move up and down along with rotation of the threaded rod, and therefore the excavator bucket structure can reach the needed working position.
本发明涉及挖泥船机械臂技术领域，且公开了一种反铲挖泥船的伸缩式机械臂，包括：吊臂结构、伸缩结构，所述吊臂结构包括主吊臂，所述主吊臂的顶部一侧固定安装有第一液压缸；所述伸缩结构包括连接块，所述连接块与第一液压缸的伸缩杆为铰接连接，所述连接块的外表面一侧固定安装有连接臂，所述连接臂的外表面顶部固定安装有两个支撑杆。通过设置的吊臂结构和伸缩结构，在装置工作时，通过第一液压缸的伸缩杆伸缩以控制连接臂的工作角度，当需要扩大挖泥范围时，通过启动第一伺服电机，使螺纹杆在连接臂内部转动，由于连接臂的限位与伸缩臂的设置，伸缩臂可跟随螺纹杆的转动进行上下移动，由此可使挖斗结构达到所需的工作位置。
