Folding telescopic working device and excavator
The invention discloses a folding telescopic working device and an excavator. The folding telescopic working device comprises a lower movable arm, a movable arm oil cylinder, an upper movable arm, a bucket rod assembly and a working piece. One end of the lower movable arm is rotationally connected with the bearing piece, and the other end of the lower movable arm is rotationally connected with the upper movable arm; one end of the movable arm oil cylinder is rotationally connected with the lower movable arm, the other end of the movable arm oil cylinder is rotationally connected with the bearing piece, and the connecting point of the movable arm oil cylinder and the bearing piece is located behind the connecting point of the lower movable arm and the bearing piece; the bucket rod assembly is of a telescopic structure, one end of the bucket rod assembly is rotationally connected with the upper movable arm, and the other end of the bucket rod assembly is rotationally connected with the work piece. The lower movable arm is compact in structure, low in gravity center under the driving posture, simple in lower movable arm limiting and beneficial to improving the driving speed and safety of the excavator.
本发明公开了一种折叠伸缩式工作装置及挖掘机，包括下动臂、动臂油缸、上动臂、斗杆组件和工作件；所述下动臂的一端与承载件转动连接，另一端与所述上动臂转动连接；所述动臂油缸的一端与所述下动臂转动连接，另一端与承载件转动连接，且所述动臂油缸与承载件的连接点位于所述下动臂与承载件连接点的后方；所述斗杆组件为可伸缩式结构，其一端与所述上动臂转动连接，另一端与所述工作件转动连接。本发明结构紧凑，行驶姿态下重心低，下动臂限位简单，有利于提高挖掘机的行驶速度以及安全性。
