Fig. 1 to 3 are schematic structural views of a converter trunnion ring hoisting device according to some embodiments of the present application, and the converter trunnion ring hoisting device according to the present application will be described below with reference to fig. 1 to 3. It should be noted that fig. 1-3 are only examples and are not intended to limit the specific shape and structure of the lifting device for the trunnion ring of the converter.

Referring to fig. 1 to 3, in this embodiment, the converter trunnion ring hoisting device includes a hanging beam 1, hanging forks 2 and hanging straps 3, the two hanging forks 2 are symmetrically disposed at two ends of the hanging beam 1, the hanging forks 2 include two hanging lugs 201 disposed at intervals, a pin 202 is disposed between the two hanging lugs 201, and the hanging straps 3 are hung on the pin 202.

In this embodiment, through using suspender 3 and hanging beam 1 complex structure, make hoist device no longer use the board hook to reduce whole hoist device's equipment and taken up the height, solved because the high restriction of factory building, lead to converter trunnion ring 5 can't lift by crane the problem.

Specifically, referring to fig. 4, four binding positions of two hanging strips 3 are symmetrically distributed on A, B, C, D four hoisting positions on the converter trunnion ring 5, so as to ensure that the converter trunnion ring 5 is stably hoisted.

Specifically, the hanging beam 1 is of an arch structure, so that the strength of the hanging beam 1 is enhanced.

In addition, the hanging strip 3 is hung on the pin shaft 202 and is not fixed, when the hanging strip 3 and the converter trunnion ring 5 are bound and hoisted, if the converter trunnion ring 5 tilts, the hanging strip 3 slides on the pin shaft 202 to adjust the converter trunnion ring 5 to be in a horizontal state, thereby avoiding the influence on hoisting due to the tilting of the position of the converter trunnion ring 5.

In some embodiments, the strap 3 is provided with an ear loop 301 at both ends. The ear rings 301 at the two ends of the hanging strip 3 are matched with the shackles, so that the hanging strip 3 is conveniently connected with the converter supporting ring 5.

In some embodiments, the hanging beam 1 is connected with a lifting device through a sling 4, and the lifting device drives the hanging beam 1 to move up and down to lift the converter trunnion ring 5.

Specifically, the hoisting equipment is a metallurgical crown block.
