Electric excavator
The invention relates to an excavator (10) provided with a movable arm (12). The excavator comprises a main electric driving system (24) and a separate fluid-driven auxiliary actuating system (32), wherein the main electric driving system (24) is provided with an electric storage unit (26) and an electric driving device (28), and the electric driving device (28) is used for moving the movable arm(12) so as to enable at least one part of the movable arm (12) to ascend and/or descend optionally by means of pivoting movement; the separate fluid-driven auxiliary actuating system (32) is used forstoring at least one part of potential energy thereof during descending of the movable arm (12) and supporting at least one part of the movable arm (12) to ascend by using the stored energy; and the auxiliary actuating system (32) is used for storing the energy and completely and automatically supporting the parts of the movable arm to ascend without any interaction with the main electric drivingsystem (24).
本发明涉及一种具有可移动动臂(12)的挖掘机(10)，包括：主电驱动系统(24)，具有蓄电单元(26)和电驱动装置(28)，电驱动装置(28)用于使所述动臂(12)移动以提升和/或降低动臂(12)的至少一部分，可选地通过枢转移动方式；以及单独的流体驱动辅助致动系统(32)，用于在动臂(12)降低期间存储其至少一部分的势能，并用于使用所存储的能量支撑动臂(12)的至少一部分的提升，其中辅助致动系统(32)用于存储所述能量，并完全自主地支撑动臂的部分的提升，而无需与主电驱动系统(24)进行任何交互。
