Technical Field

The invention relates to the technical field of metallurgy, in particular to a novel metallurgical automatic ladle overturning mechanism.

Background

In the metallurgical industry, particularly steel smelting, due to the high-temperature and high-risk working characteristics, safety becomes more and more important, and particularly in the processes of hoisting molten iron and charging iron and turning a ladle, the two processes are mainly completed by a metallurgical crane at present.

As shown in fig. 1, a conventional hot metal charging ladle turning schematic diagram is shown, a main hook 10 of a crane lifts a ladle 40 through a lifting appliance 20, an auxiliary hook 30 of the crane hangs a ladle 40 turning lifting ring, the auxiliary hook 30 of the crane lifts, and the ladle 40 turns and dumps molten iron by taking a ladle shaft as an axis.

The process needs to be manually hooked near the ladle 40, and the potential safety hazard of hurting people exists because molten iron can splash out of the ladle 40; the ladle turning is completed by manually operating the lifting of the crane main hook 10 and the crane auxiliary hook 30, once an operation error occurs, the iron charging position is inaccurate, and even molten iron is poured out of a furnace mouth (or a ladle mouth), so that a safety accident occurs.

Therefore, aiming at the defects of the traditional mechanism, a novel metallurgical automatic ladle overturning mechanism is urgently needed to be developed so as to overcome the defects in the current practical application.

Disclosure of Invention

The embodiment of the invention aims to provide a novel metallurgical automatic ladle overturning mechanism to solve the problems in the background technology.

In order to achieve the above purpose, the embodiments of the present invention provide the following technical solutions:

a novel metallurgy automatic ladle overturning mechanism comprises a lifting appliance, a ladle and an overturning shaft, wherein the overturning shaft is fixedly arranged on the outer side of the ladle, a hook at the lower end of the lifting appliance is hung on the overturning shaft, and the overturning shaft can rotate relative to the hook of the lifting appliance;

the upper end of the lifting appliance is connected with a main lifting mechanism; the ladle is also provided with a ladle turning assembly, the ladle turning assembly comprises a ladle turning seat, a ladle turning frame and a chain, the ladle turning seat is fixed on the ladle, the ladle turning frame is fixed on the ladle turning seat, the chain is arranged on the outer side of the ladle turning frame in a matching manner, one end of the chain is fixed on the ladle turning frame, and the other end of the chain is connected with an auxiliary hoisting mechanism.

As a further scheme of the invention: the ladle overturning frame is of a semicircular annular structure.
