[0002] At present, steel enterprises mainly use two modes of transportation to transport large tonnage of molten iron, one is rail-type molten iron car transportation, and the other is trackless wheeled molten iron car transportation; among them, the wheeled molten iron car transportation method for transporting molten iron ladles exceeding 200 tons generally adopts hydraulic axle-type molten iron transport vehicles; the travel drive of this hydraulic axle-type molten iron transport vehicle mainly has two forms: one is diesel engine-transfer case-hydraulic pump-motor-reducer; the other is a new energy vehicle form, in which the hydraulic motor is replaced by an electric motor, battery pack-motor-reducer.

[0003] However, although the molten iron car driven by pure battery + motor + reducer meets the needs of green development in today's society, it has some shortcomings. Because there are too many battery packs on the vehicle, the vehicle is large in size and heavy in weight, which increases the load of the entire vehicle. At the same time, the transported molten iron or molten steel has a very high temperature and is highly corrosive, which causes corrosion to the metal structure of the molten iron car. During loading and unloading, the molten iron can easily splash onto the battery pack and wires, posing a risk of leakage and explosion, causing fire and major safety hazards.

[0004] The molten iron car driven by a hydraulic motor reducer adopts a hydraulic drive system. This form requires the hydraulic pipelines to be arranged on both sides of the vehicle from the front to the back. The pipelines are complicated and have many pipeline joints. Oil leakage often occurs in the pipes and joints, which increases the maintenance cost. Summary of the invention

[0005] The purpose of the present invention is to solve the problems raised in the above-mentioned background technology. The present invention provides an electric-driven molten iron car driven by a generator set, which eliminates the battery pack, greatly reduces the layout of hydraulic pipe joints, etc., reduces the cost and frequency of maintenance, can greatly improve transportation efficiency, and reduce safety hazards.

[0008] In one embodiment of the present invention, the steering and lifting system includes a steering and lifting pump and a motor, and the motor drives the steering and lifting pump to work.

The water tank, the engine and the generator are all installed on the bracket. The water tank and the generator are both connected to the engine. The water tank and the generator are arranged on both sides of the engine. The fuel tank is connected to the engine through a pipeline.

[0010] In one embodiment of the present invention, the drive axle is a symmetrical structure, and two drive motors and two reducers are provided. The drive motors are installed at two ends of the drive axle, and a reducer is installed at the end of each drive motor.
