Abstract
The utility model discloses a high-voltage current collector for an electric excavator comprising a box, a cable inlet apparatus, a current-collection connection plate, a cable outlet pipe, a central fluctuation disk, a screw insulation rod, an electric brush rack and a collector ring, wherein the cable inlet apparatus and the current-collection connection plate are arranged on the box, the cable outlet pipe is connected with the current-collection connection plate by a bearing linkage apparatus, and the central fluctuation disk is connected with the cable outlet pipe. One end of the screw insulation rod is connected with the current-collection connection plate and the other end is connected with the bottom of the box. The electric brush rack is mounted on the screw insulation rod. A cable of the cable inlet apparatus is electrically connected with the electric brush rack. The collector ring is disposed on the cable outlet pipe, is electrically connected with an electric brush on the electric brush rack in a slidable manner and is electrically connected with a cable of the cable outlet pipe. When an upper trolley rotates, the central fluctuation disk and the collector ring in the central fluctuation disk rotate with the upper trolley, a power supply is conducted to the upper trolley by the collector ring from an electric brush part of a lower trolley, so that 360 DEG operation of the upper trolley is guaranteed and a power supply system cannot be damaged. The collector ring of the high-voltage current collector is of a single assembled type, thereby being convenient for part maintenance and replacement.
