Description

Technical Field

[0001] The utility model belongs to the technical field of molten iron ladle transfer, and in particular relates to a rotating turntable for a molten iron ladle. Background Art

[0002] The iron ladle is a casting equipment used for casting operations in the foundry workshop. It receives the molten iron in front of the furnace and then is transported to the mold by a crane for pouring. During the transportation of the iron ladle, a downturn table and a turntable are required. When in use, the iron ladle is installed on the downturn table, and the downturn table with the iron ladle installed is placed on the top of the turntable. At this time, the four sets of sliding rollers at the bottom of the downturn table roll onto the slide rails in the slide trough, and then the rotation of the turntable is used to adjust the moving direction of the iron ladle downturn table to realize the transportation of the iron ladle.

[0003] The Chinese patent application No. 202123252446.8 discloses a rotating turntable for a ladle. This patent drives a driving gear to rotate through a driving motor, drives a central gear to rotate, and then drives a turntable to rotate, thereby realizing rotational adjustment of the ladle on the inverted table at the top of the turntable, which not only increases the rotational driving force of the turntable, but also can be used to reinforce the turntable to prevent the turntable from rotating at will. However, there is no device on the turntable to limit the inverted table on which the ladle is installed. After the inverted table is pushed onto the turntable, when the turntable rotates the ladle, the sliding roller at the bottom of the inverted table may roll on the slide rail, causing the inverted table to move, causing the inverted table and the ladle to move, making the inverted table with the ladle installed on the turntable unstable, affecting the transfer effect of the turntable on the ladle. For this reason, we propose a rotating turntable for a ladle. Utility Model Content
