The invention discloses a power supply system with a cable take-up device for an electric excavator. The power supply system with the cable take-up device for the electric excavator is installed on the electric excavator and provides electric power for the electric excavator, and the power supply system with the cable take-up device for the electric excavator comprises the cable take-up device, a front support, a rear support and a via-hole-type collecting ring; one side of the front support is fixedly connected to the rear of a lower frame of the electric excavator, and the other side of the front support is hinged to the rear support; the cable take-up device is installed on the rear support, and a power supply cable is installed on the cable take-up device; the power supply cable is connected with the the via-hole-type collecting ring and provides electricity for a driving motor of the electric excavator through the via-hole-type collecting ring. The invention further discloses the electric excavator including the power supply system. According to the power supply system with the cable take-up device for the electric excavator and the electric excavator, when the electric excavator equipped with the power supply system moves or operates, barrier-free continuous power supply can be achieved, the cable can be stored or released through constant torque, and accidents caused by rolling of the electric excavator on the cable and poor winding of the cable are prevented.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a power supply system of an electric excavator with a cable take-up device and the electric excavator. Background technique [0002] As the international crude oil price continues to rise, the operating cost of fuel-based excavators continues to increase. At the same time, the concept of low-carbon and environmental protection has increasingly become a new concept in product design. Electric excavators were born due to luck, but most electric excavators are not equipped with cable take-up devices, resulting in frequent accidents such as machines rolling over cables. Some electric excavators with cable take-up devices are due to mechanism design and operation. It affects the rotation stability of the excavator, and there are generally problems such as winding confusion during cable retraction, limiting the climbing ability of the excavator, and posing hidden dangers to operati...
