移動出来るべく取付られている。A rail 12 is placed at a required distance from the axis of the pouring nozzle.
A frame 13 is fixed to the bottom 9a of the ladle 9 serving as a molten metal container, and a mounting member 8 is attached to the frame 13 by a connecting member 16 that moves in conjunction with the lower metal frame 6 on the rail 12. Installed as much as possible.
更に該取付部材８にはベアリング１０を介して回転可能
にノズル受腕支持部材１１が取付けられている。Furthermore, a nozzle receiving arm support member 11 is rotatably attached to the attachment member 8 via a bearing 10.

例に釦いては、ロングノズル取付ケーシング７ａからア
ーム１９を突出させ、該アーム１９をロングノズル掛止
部１８に単に受載させることによって構成している。A long nozzle latching portion 18 is provided at the free end of the nozzle receiving arm member 17, and the long nozzle latching portion 18
Although various forms of the structure are already known, in this embodiment, the arm 19 is made to protrude from the long nozzle mounting casing 7a, and the arm 19 is simply received on the long nozzle latching part 18. It is composed of
オた２０は取付部材８に取り付けられている旋回停止杆

グノズル受腕部材１７の旋回を停止ないし位置決めし、
ロングノズル受腕部材１７の昇降を前述したリンク機構
２１により可能とするものである。Reference numeral 20 is a swing stop rod attached to the mounting member 8, which temporarily stops or positions the long nozzle receiving arm member 17 at the position shown in FIG. 1, as will be described later.
The long nozzle receiving arm member 17 can be raised and lowered by the link mechanism 21 described above.
ついで上記構成を有する装置においてロングノズル交換
支持の作動について述べる。Next, the operation of long nozzle exchange support in the apparatus having the above configuration will be described.

In the case of Fig. 1, if you move it to the left, the nozzle receiving arm member 1
1 is raised, and the long nozzle 7 is fitted and attached to the lower nozzle brick 4.
この嵌合装着は油圧シリンダー１４によって装着支持さ
れているので、その支持は確実になされている。Since this fitted attachment is supported by the hydraulic cylinder 14, the support is ensured.
