Semi-automatic tracking mode power supply system of electric excavator

Abstract

The invention relates to a semi-automatic tracking mode power supply system of an electric excavator, and belongs to the field of electric excavator power supply technologies. The semi-automatic tracking mode power supply system of the electric excavator achieves the purposes of supplying power in a tracking mode and improving the range of activity and maneuverability and flexibility effectively. According to the technical scheme, a distribution box used for driving a motor and distributing power to the motor is arranged on an electric excavator body, the electric excavator body is provided with a crawler-type power supply trolley with a wireless control system, and the crawler-type power supply trolley is used for tracking the movement of the electric excavator body and supplying power to the electric excavator body continuously. The semi-automatic tracking mode power supply system is simple in structure, convenient to use and widely used in power supplying of electric excavators.

Description

technical field [0001] The invention relates to a semi-automatic tracking power supply system for electric excavators, belonging to the technical field of electric excavator power supply. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials above or below the bearing surface and load it into a transport vehicle or unload it to a stockyard. At present, excavators on the market are mainly excavators with internal combustion engines as the power system. Such excavators need to burn a large amount of fuel during operation, have high energy consumption, serious waste of resources, and easily cause environmental pollution. [0003] With the continuous increase of fuel prices, the maintenance and use costs of excavators with internal combustion engines as power systems are increasing year by year, and at the same time, problems such as inability to use in some special environments (such as flammable gas and dust) have made t...

AI Technical Summary

Problems solved by technology

Excavators currently on the market are mainly excavators with internal combustion engines as the power system. This kind of excavator needs to burn a large amount of fuel during work, resulting in high energy consumption, serious waste of resources, and easy to cause environmental pollution.

[0003] With the continuous rise of fuel prices, the maintenance and use costs of excavators with internal combustion engines as power systems are increasing year by year. Excavators that use electric motors instead of engines as power systems have appeared on the market. This kind of excavator is low in cost, safe and environmentally friendly, but this kind of electric excavator needs to drag long cables, and the range of activities is greatly restricted. There are also great safety hazards in pulling the cables. At the same time, this kind of electric excavator has high production and maintenance costs, large volume, and poor maneuverability.
