Description
Technical field
The present invention relates to a kind of pavilion stove that can overturn that comprises the suspension of swing arm that has.
Background technology
Such converter is open such as obtaining from DE 4327640 and from US 6228320.Swing arm is sentenced herein articulated manner and correspondingly is connected on the bof vessel and with another end with one of them end by means of the swing arm bearing of sphere and is connected on the sustained ring.The swing arm bearing of described sphere has the pin that passes as supporting pin from described swing arm, wherein said pin is supported on the described bof vessel by a pair of support contact pin respectively in both sides or is supported on the described sustained ring.Described support contact pin with pin-and-hole is welded on the described sustained ring and is welded in other words on the described bof vessel.But, by the welding distortion that produces along with welding, be provided for admitting the only with limitation alignment of pin-and-hole of the paired support contact pin of identical pin.This is so that the difficult of packing into of pin.Can not or only after very large expense, could after the described support contact pin of welding, carry out common processing to described pin-and-hole because member is big or small.In order to simplify packing into of described pin, known that the support contact pin bearing with sphere is encased in the pin-and-hole of described support contact pin, can partly compensate alignment error by means of the support contact pin bearing of described sphere.
But, the swing arm bearing of described sphere and spherical support contact pin bearing work in-process and in installation, cause significant overhead.
Summary of the invention
Task of the present invention is, provide a kind of have a kind of swing arm is fixed on the converter that can overturn of the mode on converter and the sustained ring, described fixing mode allow easily to pack into described pin and representing with respect to prior art a kind of more easy and cost is more cheap can install quickly and the connection of being connected.
This task is resolved by a kind of converter that can overturn, and this converter comprises:
-one bof vessel;
-one sustained ring;
-one suspension, wherein said bof vessel is connected with described sustained ring by described suspension;
And wherein said suspension comprises
-at least one swing arm, this swing arm are fixed on the described bof vessel and with another end with one of them end by means of the swing arm bearing of sphere and are fixed on the described sustained ring,
-and at least one is used for stabilizing deyice that the motion with respect to described sustained ring to described bof vessel limits in case of necessity,
And the swing arm bearing of wherein said sphere has the pin that passes from described swing arm, described pin is supporting described swing arm, and wherein said pin is supported on the described bof vessel by support contact pin or is supported on the described sustained ring,
It is characterized in that,
At least one pin in the described pin is supported on the described bof vessel by a unique support contact pin or is supported on the described sustained ring, and this root pin to support by at least two swing arm through holes be the swing arm of its distribution.
The swing arm of distributing to pin refers to the swing arm by this pin supporting.
By the present invention, at least one pin in the described pin is supported on the described bof vessel according to the characteristic part of claim 1 by a unique support contact pin or is supported on the described sustained ring.But also can be supported by many preferred all pins like this.Be supported on the described bof vessel by a unique support contact pin or be supported on pin on the described sustained ring for every, applicable this point, namely its to support by at least two swing arm through holes be the swing arm of its distribution.
Because described pin only is supported in the unique support contact pin by the present invention, so for by converter of the present invention, having avoided to provide the as far as possible such difficulty of pin-and-hole of alignment a pair of support contact pin in described converter or on the described sustained ring with respect to prior art.
Because described pin is by the swing arm of at least two swing arm through holes under supporting, thus described two swing arm through holes must be disposed aligned, in order to can pack described pin into.The making of the swing arm through hole that is disposed aligned in other words for make the swing arm through hole so the processing of the swing arm through hole implemented in order to can pack pin into of alignment for swing arm, be compared in the described converter or paired support chip on the described sustained ring simply too much.Why like this, be because swing arm is than described converter or the much smaller member of sustained ring.Correspondingly alignment error can not occur, must compensate described alignment error the way of pin and pack into for the oscillating bearing of the sphere in being encased in the swing arm through hole.Therefore, use the swing arm bearing of spherical oscillating bearing-sphere and the way of the type of the supporting contact pin bearing of sphere with respect to prior art together with it, necessarily seldom use spherical oscillating bearing, this has reduced the maintenance expense in the described converter and has allowed to use suspension more simple and that cost is more cheap.
Preferred applicable this point, be that the pin of the swing arm bearing of described sphere correspondingly is supported on the described bof vessel by a unique support contact pin on two ends of swing arm and correspondingly is supported on the described sustained ring by a unique support contact pin, and described pin correspondingly to support by at least two swing arm through holes be the swing arm of its distribution.In described suspension, farthest utilize in this way the advantage with respect to prior art of the present invention.
But also can consider mixed form, the pin of the swing arm bearing of described sphere is supported on the described bof vessel by a unique support contact pin on an end of swing arm or is supported on the described sustained ring for described mixed form, and the pin of the swing arm bearing of described sphere then supports contact pin according to prior art by two and is supported on the described sustained ring or is supported on the described bof vessel on another end of described swing arm.In such a case, only the described pin that supports by unique support contact pin is supporting the swing arm that distributes by at least two swing arm through holes, and another root pin is then supporting described swing arm by a unique swing arm through hole.
Described converter is such as being used for steel-making.
Concerning each swing arm bearing, there is a pin.Described pin forms the supporting pin of described swing arm bearing.
Swing arm can so consist of, so that it has the centering part, this centering part has the bifurcation point that is divided at least two end pieces at least one end.In at least two end pieces of the same end of described swing arm, settle through hole, be also referred to as the swing arm through hole.Described swing arm through hole passes corresponding end pieces.Described swing arm through hole is settled as far as possible alignedly, in order to can pack described pin into.
Swing arm also can so consist of, so that it has two swing arm lateral parts that are arranged side by side with a determining deviation, above described swing arm lateral parts is fixed on each other by the lateral parts web member.On each end of such swing arm, in described two swing arm lateral parts, settled through hole, be also referred to as the swing arm through hole.Described swing arm through hole passes corresponding swing arm lateral parts.Described swing arm through hole is settled as far as possible alignedly, in order to can pack described pin into.
