This utility model discloses a novel electric gear pump device for electric shovel lubrication truck, relating to the technical field of oil filling trucks for mining equipment. It includes a power compartment, a grease compartment, and a hose reel compartment. The power compartment includes a diesel generator set, a grease lubricating oil tank, a black oil lubricating oil tank, an electric gear pump set, an ultrasonic level gauge, a hose reel, a color paperless recorder, an electrical control cabinet, and a fire extinguisher. A ground-based oil replenishment system is installed on the side of the grease compartment. Ultrasonic level gauges are installed on the three oil tanks within the grease compartment to monitor the oil level in real time. These level signals are transmitted to the color paperless recorder installed on the electrical control cabinet panel. When absorbing oil, if the oil level in the tank is lower than the minimum absorbing level, the paperless recorder will issue a low-level alarm, reminding the operator to stop refueling to prevent the oil pump from running dry and being damaged. When replenishing oil in the tank, the paperless recorder will issue a high-level alarm, prompting the operator to stop oil supply to avoid oil overflow.
