Two-section arm assembly with hinge points capable of being automatically switched and engineering machinery
The two-section arm assembly capable of automatically switching the hinge points comprises a front arm body, a front arm body lug plate, a rear arm body, a step pin shaft and a connecting rod, the front arm body lug plate is arranged on the lower plane of the front arm body, a plurality of front arm body lug plate hinge point holes are formed in the front arm body lug plate, and the step pin shaft is arranged in the front arm body lug plate hinge point holes. Hinge point hole sliding grooves are formed between the front arm body lug plate hinge point holes, the step pin shaft comprises a first shaft body, a first sliding way body, a second shaft body and a second sliding way body which are sequentially connected, when the step pin shaft is located at the complete retracting position, the first shaft body and the second shaft body are located in the front arm body lug plate hinge point holes, and when the step pin shaft is located at the complete pushing-out position, the second shaft body is located in the front arm body lug plate hinge point holes. The first slide way body and the second slide way body are located in a hinge point hole of a front arm body lug plate, and in the state, the step pin shaft can slide along a hinge point hole sliding groove.
本发明公开了一种铰点可自动切换的二节臂总成及工程机械，其中铰点可自动切换的二节臂总成，包括前臂体、前臂体耳板、后臂体、阶梯销轴和连杆，前臂体耳板设置在前臂体下平面上，前臂体耳板上设有若干个前臂体耳板铰点孔，前臂体耳板铰点孔之间设有铰点孔滑槽，阶梯销轴包括顺次连接的第一轴体、第一滑道体、第二轴体和第二滑道体，当阶梯销轴处于完全收回位置时，第一轴体和第二轴体位于当前前臂体耳板铰点孔中，当阶梯销轴处于完全推出位置时，第一滑道体和第二滑道体位于当前前臂体耳板铰点孔中，此状态下阶梯销轴能沿铰点孔滑槽滑动。
