Description
Technical Field
The utility model relates to a transportation device in an electrolytic aluminum factory, in particular to an electric maintenance vehicle resisting the interference of an electrolytic aluminum magnetic field.
Background
The electrolytic aluminum plants in the electrolytic aluminum plants are often transported to a repair shop by using a repair car for repair. The maintenance vehicle commonly used at present is generally driven by a diesel engine. The diesel engine mainly uses diesel fuel, so that the cost is high, the smoke is large, and the environment in a factory building is influenced. In order to save the cost and improve the environmental quality in the factory building, the electric maintenance vehicle driven by electric power is provided to replace the traditional diesel vehicle at present, the fuel cost can be saved by the scheme, and the environmental quality in the factory building can be effectively improved. However, when the existing electric maintenance vehicle passes through a bus channel in a factory building, the current is sharply reduced, the vehicle is trembled during running, and the electric maintenance vehicle is stopped instantly and can only be pushed by manpower; the situation greatly influences the popularization and application of the electric maintenance vehicle in the electrolytic aluminum factory.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an anti electrolytic aluminum magnetic field interference's electronic tool car. The utility model discloses can effectively avoid electronic tool car current unusual in the interior generating line passageway of electrolytic aluminum factory.
The technical scheme of the utility model: an electric maintenance vehicle capable of resisting electrolytic aluminum magnetic field interference comprises a frame, wherein a cab and a carriage are sequentially arranged at the front end and the rear end above the frame, front wheels and rear wheels are sequentially arranged at the front end and the rear end below the frame, the front wheels are connected with the frame through a suspension system, and the front wheels are also respectively connected with a power-assisted steering mechanism and an electric brake system; the rear wheel is connected with the frame through a plate spring damping system, the rear wheel is also connected with the motor through a rear axle transmission system, and the rear wheel is also connected with an electric brake system; the frame below the carriage is also provided with a battery for providing power, a motor controller for controlling the motor and a battery management system for managing the battery; the motor controller and the battery management system are packaged in an electromagnetic shielding box arranged below the carriage; the cable connecting the motor, the battery, the motor controller and the battery management system is an electromagnetic shielding cable.
In the electric maintenance vehicle capable of resisting the interference of the electrolytic aluminum magnetic field, the electromagnetic shielding box is a nickel alloy electromagnetic shielding box.
Advantageous effects
Compared with the prior art, the inventor carries out line detection and structural abnormality analysis on the maintenance vehicle in order to overcome the problems that when the electric maintenance vehicle passes through a bus channel in a factory building, the current is rapidly reduced, and the vehicle runs and has towering, but the line connection abnormality is not found; after a plurality of grops, the inventor compares and analyzes the environment of the bus duct with other areas, and finds that the electromagnetic field intensity in the bus duct is obviously stronger than that in other areas; after this conclusion, the inventors have experimentally found that: the strong electromagnetic field can cause serious electromagnetic interference to a control core motor controller and a battery management system of the electric maintenance vehicle, further cause the current to drop sharply, and cause the condition that the vehicle runs and tregs. After the reasons causing the above situations are known, the inventor packages the motor controller and the battery management system in the electromagnetic shielding box, so that the motor controller and the battery management system are prevented from being interfered by a strong electromagnetic field when working, and meanwhile, the connecting cable is changed into an electromagnetic shielding cable, so that the interference of the strong electromagnetic field is further avoided; through the structure, the electric maintenance vehicle is prevented from stopping in the bus channel in the plant, and the normal use of the electric maintenance vehicle is effectively ensured.
