Rotary excavating arm for small-section shallow-buried excavation of electric power tunnel
The invention belongs to the technical field of tunnel and underground engineering construction, and particularly relates to a rotary excavating arm for a small-section shallow-buried excavation electric power tunnel. According to the scheme, the rotary excavating arm for the small-section shallow-buried excavation electric power tunnel comprises a deflection swing arm assembly and a bucket rod arm and bucket assembly; the deflection swing arm assembly comprises a movable arm, a deflection assembly used for driving the movable arm to act and a movable arm oil cylinder. The bucket rod arm and bucket assembly comprises a first bucket rod arm, a second bucket rod arm and a bucket; the bucket is mounted on the second bucket rod arm, and the first bucket rod arm is connected with the movable arm; the first bucket rod arm and the second bucket rod arm are connected through a rotation speed reducing mechanism. According to the scheme, the main body structure is compact and reasonable, the rotary speed reducer is arranged, the bucket can rotate by +/-180 degrees, operation is flexible, and the problems of over-excavation and under-excavation of the tunnel section are avoided.
本发明属于隧道与地下工程施工技术领域，具体涉及一种小断面浅埋暗挖电力隧道回转式挖掘臂。本方案小断面浅埋暗挖电力隧道回转式挖掘臂，包括偏摆动臂组件和斗杆臂铲斗组件；偏摆动臂组件包括动臂，以及用于驱动动臂动作的偏摆组件和动臂油缸；斗杆臂铲斗组件包括第一斗杆臂、第二斗杆臂和铲斗；铲斗安装在第二斗杆臂上，第一斗杆臂与动臂相连接；第一斗杆臂、第二斗杆臂之间通过回转减速机构连接。本方案主体结构紧凑合理，设置有回转减速器，可使铲斗实现±180°旋转，操纵灵活，避免隧道断面超挖和欠挖问题的发生。
