Description
Technical field
The utility model is related to technical field of metallurgical machinery, and in particular to a kind of tool of adjustment converter shell position.
Background technology
During wine steel steel melting converter shell is replaced, need to carry out leveling and adjusting to the center of furnace shell and oxygen rifle.Past turns
The tool that stove furnace shell adjustment centering uses has jack, jack, rolling bar, sledgehammer, and personnel's input amount is big, time-consuming and laborious.And it overhauls
Space is limited, can not use other service kits, but the tools such as jack, jack, rolling bar are from great, converter trunnion ring position
Narrow, the activities such as operation such as converter shell adjustment easily injure operating personnel in operation process, security risk is larger.In addition by
It is placed on furnace shell upper support seat and backing ring between plane in rolling bar, and is contacted for line, in addition converter shell dead weight is larger, and pressed
On rolling bar, frictional force is big, and rolling bar self-view is not easy to adjust, and furnace shell rotation is difficult, and operating efficiency is low, and the prior art can not
It solves the above problems.
The difficult, cost of overhaul that purpose of the utility model is to solve the adjustment of the position of converter shell in the prior art
It is high and there are problems that security risk, provide a kind of tool of adjustment converter shell position.
Utility model content
In order to achieve the above object, the utility model uses following technical scheme：
A kind of tool of adjustment converter shell position, including waist-drum-shaped rolling element, adjustment jack and lifting jack,
And lifting jack is located between the ring flange on converter shell top and the backing ring outside converter shell, and backing ring is additionally provided on backing ring
The top of pedestal, backing ring is equipped with multiple upper support seats, and upper support seat is arranged in the bottom of ring flange, each upper support seat and support
It is placed with waist-drum-shaped rolling element between circle, adjustment jack is additionally provided between upper support seat and backing ring pedestal.
It is further improved as the utility model, waist-drum-shaped rolling element is the small symmetrical structure in both ends broad in the middle, and waist drum
The length of a diameter of 80mm of type rolling element middle, waist-drum-shaped rolling element are 150mm.
It is further improved as the utility model, adjustment jack is screw jack.
It is further improved as the utility model, waist-drum-shaped rolling element is three groups.
The utility model compared with the existing technology, has the advantages that：
The tool of the adjustment converter shell position of the utility model utilizes lifting jack stand converter shell, is turning later
Waist-drum-shaped rolling element is set between the backing ring and upper support seat of stove furnace shell, the setting adjustment thousand between upper support seat and backing ring pedestal
Jin top is point contact between such waist-drum-shaped rolling element and the upper support seat and backing ring of converter shell, and frictional force reduces, accordingly
The specification of adjustment jack also becomes smaller, and waist-drum-shaped rolling element self-view is easily adjusted, and furnace shell rotation is easy, and is effectively saved people
Power, time improve overhaul efficiency, and the utility model is of simple structure and low cost, easy to operate, safe and reliable, can
To be used for a long time.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-3, a kind of tool of adjustment converter shell position, including 4, the two 20 tons of adjustment of waist-drum-shaped rolling element
Jack 3 and three 50 tons of lifting jack 7, wherein lifting jack 7 are located at the ring flange 8 on 1 top of converter shell and turn
Between backing ring 2 outside stove furnace shell 1, it is additionally provided with pedestal 6 on backing ring 2, the top of backing ring 2 sets that there are three upper support seats equipped with top
5, and upper support seat 5 is arranged between the bottom of ring flange 8, each upper support seat 5 and backing ring 2 and is equipped with waist-drum-shaped rolling element 4,
Waist-drum-shaped rolling element 4 is the small symmetrical structure in both ends broad in the middle, and a diameter of 80mm of waist-drum-shaped rolling element middle, waist-drum-shaped
The length of rolling element is 150mm.It is equipped with screw type between upper support seat 5 and pedestal 6 and adjusts jack 3.
When operation, it is placed between backing ring 2 and ring flange 8 with three 50 tons of lifting jack 7 and pushes up converter shell 1
It rises, a waist-drum-shaped rolling element 4 is respectively placed below 3 upper support seats 5 of converter shell 1.Later by three 50 tons of lifting
Jack 7 is slowly fallen after rise, and upper support seat 5 is fallen on waist-drum-shaped rolling element 4.
Two 20 tons of adjustment jack 3 is placed between pedestal 6 and upper support seat 7 later, slow operation adjustment thousand
Jin top 3, the rotation of converter shell 1 is realized by adjusting the self-view of waist-drum-shaped rolling element 4, until 1 centering of converter shell
It finishes.
Converter shell 1 is jacked up with three 50 tons of lifting jack 7 again later, by the waist-drum-shaped of 5 lower section of upper support seat
Rolling element 4 takes out, then three 50 tons of lifting jack 7 is slowly fallen after rise, and upper support seat 5 is fallen on backing ring 2, converter shell 1
Leveling and adjusting finishes.
