Loader eccentric wheel assisting movable arm lifting device
The invention discloses a loader eccentric wheel assisting movable arm lifting device. The device comprises a movable arm, two hydraulic cylinders and several eccentric wheel energy-storage mechanisms. One ends of the eccentric wheel energy-storage mechanisms are hinged to the movable arm, the other ends of the eccentric wheel energy-storage mechanisms are hinged to a loader front frame, springs are arranged on the loader front frame, when the front end of the movable arm descends from a high position to a low position, the movable arm rotates downwards around the rear end of the movable arm,the springs are arranged to deform under the action of the gravity of the movable arm and retraction pull force of the hydraulic cylinders, the several eccentric wheel energy-storage mechanisms storeenergy, and when the front end of the movable arm is lifted from the low position to the high position, the movable arm rotates upwards around the rear end of the movable arm, the springs are arrangedto recover from a deformation state to a non-deformation state, and the several eccentric wheel energy-storage mechanisms release energy, so that lifting assisting of the movable arm is achieved, anda power fuel is further saved.
一种装载机偏心轮助力动臂举升装置，包括动臂，两个液压缸；若干偏心轮蓄能机构，其一端分别铰接于所述动臂上，其另一端分别铰接于装载机前车架上，其上分别设置有弹簧，在所述动臂的前端由高位置向低位置下降时，所述动臂围绕其后端向下旋转的过程中，所述弹簧分别设置为在所述动臂自身重力和所述液压缸回缩拉力的作用下变形，所述若干偏心轮蓄能机构储能，在所述动臂的前端由低位置向高位置举升时，所述动臂围绕其后端向上旋转的过程中，所述弹簧分别设置为由变形状态向非变形状态恢复，所述若干偏心轮蓄能机构释放能量，实现助力动臂举升，进一步实现节约动力燃料。
