Electric excavator
The invention provides an electric excavator, and relates to the technical field of engineering machinery. The electric excavator comprises an excavator device and a trailer power supply device. The excavator device comprises an upper trolley and a lower trolley, and the upper trolley is rotatably connected with the lower trolley. The trailer power supply device comprises a trailer, an outgoing line mechanism and an output cable, the trailer is connected with the lower trolley, the outgoing line mechanism is rotatably connected with trailer, the output cable is arranged on the trailer, and theoutput cable is connected with the upper trolley through the outgoing line mechanism to supply power to the excavator device. When the output cable swings caused by the rotation of the upper trolleyrelative to the lower trolley, the outgoing line mechanism following with the output cable together rotates relative to the trailer. The cable of the electric excavator is difficult to wear, and the work reliability is high.
本发明提供了一种电动挖掘机，涉及工程机械技术领域。电动挖掘机包括挖掘机装置和拖车供电装置。挖掘机装置包括上车和下车，上车转动连接于下车。拖车供电装置包括拖车、出线机构和输出电缆，拖车连接于下车，出线机构转动连接于拖车，输出电缆设置于拖车，输出电缆经过出线机构接入上车以向挖掘机装置供电。当上车相对于下车转动导致输出电缆摆动时，出线机构随输出电缆一同相对拖车转动。电动挖掘机电缆不易磨损，工作可靠性高。
