Problems solved by technology
When there is no grid power supply in remote suburbs, the pure AC electric loader will not be able to work; if there is AC power, the pure battery loader still uses the battery, not only the AC-DC conversion is required, the efficiency is reduced, but also greatly shortened battery life
The existing pure battery electric loaders on the market have small torque and overload capacity at low speeds, which often lead to unsatisfactory operation results
In addition, the power cable of the existing AC electric loader is dragged on the ground or erected on a high pole, which is inconvenient for the loader during operation, and will also wear the cable, which brings potential safety hazards

The invention discloses an alternating current / storage battery dual-purpose electric loader. According to the technical scheme, a power device is divided into an AC power source power device and a storage battery power device. Through the mode that two sets of power devices are arranged at the same time, the singular power supply mode of a traditional electric loader is solved, that is, either a storage battery is used or an AC power source is used. According to the alternating current / storage battery dual-purpose electric loader, electric energy replaces fuel oil, the work cost can be greatly reduced, pollution to the environment is avoided, compared with a mode that a fuel engine supplies power, more energy is saved, the environment is protected, and the maintenance cost is low; two energy supply modes exist at the same time, the electric loader is free of limit of the environment and more convenient to use, and the proper energy supply mode is selected according to the work environment.
Description
technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to an electric loader with alternating current / storage battery dual-purpose. Background technique [0002] The existing loaders on the market, whether they are wheel loaders or crawler loaders, mainly use fuel engines as the power source, which not only consumes a lot of fuel, but also has high operating costs, and also causes great pollution to the environment. When the fuel engine is working, the harsh external environment on the construction site greatly shortens the life of the engine, so the maintenance cost of the engine is also very high. With the increasingly prominent energy and environmental issues, the use of electric loaders can not only greatly reduce their operating costs and achieve zero emissions, but also greatly reduce the maintenance costs of loaders. [0003] Traditional electric loaders are either directly powered by batteries or power...
