【考案の詳細な説明】
本考案は、取鍋用トラニオンに関し、詳細には摩耗部を
交換自在にした取鍋用トラニオンに関する。[Detailed Description of the Invention] The present invention relates to a trunnion for a ladle, and more particularly to a trunnion for a ladle in which the worn part is replaceable.
取鍋の１〜ラニオンは、クレーンのフックとの摩擦によ
り摩耗した場合トラニオンの強度の低下を招く。If the ladle 1 to runners wear out due to friction with the crane hook, the strength of the trunnion will decrease.
このようなトラニオンを使用していると、溶鋼の運搬時
にトラニオン軸が折損する恐れがあるため、トラニオン
部のみの取替を実施していた。If such a trunnion is used, there is a risk that the trunnion shaft may break during transportation of molten steel, so only the trunnion portion has been replaced.
１〜ラニオン部は、溶接構造であるため、トラニオン全
体の取替は、時間も長くががりがり費用も高くついた。Since the trunnion part 1 to 1 has a welded structure, replacing the entire trunnion takes a long time and is expensive.
本考案は、このような従来の取鍋用Ｉ・ラニオンの欠点
を解消するため創案されたものであり、摩耗部を２つ割
りスリーブで被うことにより、上記欠点を解消している
。The present invention was devised to eliminate the drawbacks of the conventional I-runion for ladle, and the above-mentioned drawbacks are overcome by covering the worn part with a split sleeve.
以下添付図面を参照して本考案について説明する。The present invention will be described below with reference to the accompanying drawings.
第１図および第２図は、トラニオン１にクレーンのフッ
ク２が係合した状態の取鍋３を示す。1 and 2 show the ladle 3 with the trunnion 1 engaged with the hook 2 of the crane.
これら図から明らかなようにクレーンのフック２か読合
するのは、１〜ラニオン１の中央部であって、この部分
は、他の部分より、径が小さくなっている。As is clear from these figures, the hook 2 of the crane is connected to the middle part of the runner 1 to the runner 1, and this part has a smaller diameter than the other parts.
これは、クレーンのフック２がトラニオン１から容易に
外れないようにすることおよび後述する２つ割りスリー
ブ４，４′の嵌め込みを容易にするためである。This is to prevent the hook 2 of the crane from easily coming off the trunnion 1 and to facilitate fitting of the two-split sleeves 4, 4', which will be described later.
トラニオン１は、第３図に示すように取鍋本体の側壁に
溶着された取付部５と、径が小のスリーブ嵌合部６と、
最外端部のフランジ部７とがら戊る。As shown in FIG. 3, the trunnion 1 includes a mounting part 5 welded to the side wall of the ladle body, a sleeve fitting part 6 having a small diameter,
The flange portion 7 at the outermost end is hollowed out.
トラニオン１は一体的な棒状体であって、取鍋３の側壁
の上端から若干下方の位置がら水平方向に突出している
。The trunnion 1 is an integral rod-shaped body that projects horizontally from a position slightly below the upper end of the side wall of the ladle 3.
スリーブ嵌合部６に嵌合される２つ割りスリーブ４．４
’は、横断面が半円形で゛あって、Ｉ・ラニオン１の中
心軸に対して、上下又は左右がら嵌め込むと、長手方向
に延長する側端部が互いに当接するようになっている。Two-piece sleeve 4.4 fitted into sleeve fitting part 6
' has a semicircular cross section, and when fitted from above and below or from the left and right with respect to the center axis of the I-runion 1, the side ends extending in the longitudinal direction abut each other.
これらスリーブ４，４′の両端には、トラニオンの軸に
対して半径方向に突出するフラン′ジ８を有し、スリー
ブ゛’４．４’をトラニオンの嵌合部６に嵌合したとき
、このスリーブ４，４′の最外周部か斗うニオン１のフ
ランジの最外周部と同一平面にあるようになっている。Both ends of these sleeves 4, 4' have flanges 8 that project radially with respect to the axis of the trunnion, and when the sleeves 4, 4' are fitted into the fitting part 6 of the trunnion, The outermost periphery of the sleeves 4, 4' is on the same plane as the outermost periphery of the flange of the corresponding nion 1.
これらスリーブ４．４′は、嵌合後トラニオン部オンし
てネジ９により固定される。After these sleeves 4,4' are fitted, the trunnions are turned on and fixed with screws 9.
このネジ９はトラニオン１のフランジ部分を水平方向に
貫通し、次にスリーブ４゜４′のフランジ８の孔にムに
込まれる。This screw 9 passes horizontally through the flange portion of the trunnion 1 and is then inserted into a hole in the flange 8 of the sleeve 4° 4'.
次にこれらスリーブの長手方向に沿う当接部が溶接によ
って接合され互いに一体的構造とされる。Next, the longitudinal abutting portions of these sleeves are joined by welding to form an integral structure.
このような構造のトラニオン１を設けた取鍋が長時間使
用されてスリーブ４，４′が摩耗すると、上記接合部を
溶断し、新しいスリーブ４．４’（例えば５４５Ｃを焼
入れして使用）と交換すればトラニオン１全体を交換す
ることなく、速やかに使用できる。When a ladle equipped with a trunnion 1 having such a structure is used for a long time and the sleeves 4, 4' wear out, the above-mentioned joint is cut by melting and a new sleeve 4, 4' (for example, 545C is hardened and used) is replaced. If replaced, the trunnion 1 can be used immediately without having to replace the entire trunnion 1.
従って、本考案に係るトラニオン１は、半永久的に使用
でき、取替に要する時間が短時間で済みかつ費用もわず
かでよいという種々の利点を有する。Therefore, the trunnion 1 according to the present invention has various advantages in that it can be used semi-permanently, the time required for replacement is short, and the cost is small.
なお本考案の適用範囲は取鍋用トラニオンに限定するも
のではなく、重量物を支持する同種のトラニオン部全般
を含むものとする。The scope of application of the present invention is not limited to trunnions for ladle, but includes all similar trunnions that support heavy objects.
