The charging frame 3 can be replaced and installed on the pipe body 2 for charging operations, the pushing frame 4 can be replaced and installed on the pipe body 2 for laying operations, or the slag plate 5 can be replaced and installed on the pipe body 2 for slag cleaning operations. That is to say, the front-end working part of the multifunctional charging vehicle of this embodiment can be flexibly configured with corresponding working mechanisms according to different operation requirements, effectively reducing the dependence on diversified mechanical equipment and reducing the overall cost of on-site operations in metallurgical smelting processes.

[0032] Preferably, in this embodiment, the lifting swing arm 6 includes a connecting frame and a plurality of synchronously retractable hydraulic rods, the turntable 7 is arranged on the connecting frame, the fixed ends of the plurality of hydraulic rods are hinged on the wheeled vehicle body 1, and the telescopic ends of the plurality of hydraulic rods are hinged on the connecting frame, so that the connecting frame can be lifted and lowered by the synchronous extension and retraction of the telescopic ends of the plurality of hydraulic rods.

[0033] Preferably, the wheeled vehicle body 1 is driven by a motor to rotate the wheels, the motor, the lifting swing arm 6, the turntable 7 and the operating table are all connected to the controller signal, and the wheeled vehicle body 1 is powered by a power connection line.

[0034] Preferably, a flange is installed at one axial end of the tube body 2 , and the flange is axially fixed to the turntable 7 .

[0035] Preferably, see Figure 1 、 Figure 2 and Figure 4 A limit plate 8 is installed at the other axial end of the tube body 2, and a push-pull rod that can move axially is passed through the tube body 2.
