Detailed Implementation
[0012] To make the above objectives, technical solutions and beneficial effects clearer and more explicit, the present invention will be described in detail below with reference to the accompanying drawings.
[0013] like Figures 1-5 As shown, the converter molten iron transfer device includes a track 1, a transfer car 2, a molten iron ladle 6, and a lifting shaft 5;
[0014] The transfer vehicle 2 is equipped with support legs 3 at the bottom, and casters 8 are provided on the bottom surface of the support legs 3. The casters 8 at the bottom of the transfer vehicle 2 are placed in the track 1. The carriage 4 is equipped with a fixing groove 7, and a ladle 6 is placed in the fixing groove 7. The ladle 6 can be detached and placed in the carriage 4. The bottom of the carriage 4 is equipped with a lifting shaft 5. The lifting shaft 5 can adjust the overall height of the carriage 4, raising the carriage 4 to facilitate the collection of molten iron. The transfer vehicle 2 is an AGV trolley that runs automatically on the track 1.
[0015] The AGV is equipped with a drive unit 12 at its bottom, which consists of an electric motor and a reducer. The electric motor is a YZ series lifting and metallurgical motor, and the power of the motor can be selected according to the rated tonnage of the electric flatbed truck. The reducer adopts the heavy-duty standard of the lifting and transportation industry. The AGV body is made of refined cast steel, which is not easy to deform, has a generous appearance, and is sturdy and durable. The AGV is equipped with energy-saving lights at its bottom and a control cabinet at its bottom. The control system is equipped with leakage protection switches, overload protection, and emergency power-off control components, ensuring that the transmission performance, control performance, and protection performance are safe, accurate, and reliable, and that it can stop safely in an emergency.
[0016] The carriage 4 contains two molten iron ladles 6. Each molten iron ladle 6 includes a ladle body 9. Rotating shafts 10 and driven shafts 11 are provided on the left and right sides of the ladle body 9. A driving device 12 is provided on the side of the rotating shaft 10. A turntable 13 is connected to the side of the driving device 12. A hanging column 14 is connected to the side of the ladle body 9. A crossbeam 15 is connected to the top of the hanging column 14. A hook 16 is provided on the top surface of the crossbeam 15. A discharge port 17 is provided at the top edge of the ladle body 9. An insulated inner liner 18 is provided inside the ladle body 9.
