Description

Technical Field

[0001] The utility model belongs to the technical field of ladle dumping, in particular to a ladle dumping device. Background Art

[0002] A ladle is a container for holding molten steel, and is used in steel mills, foundries, and other factories to receive molten steel from open-hearth furnaces, electric furnaces, or converters for pouring. In the prior art, when pouring molten steel from a ladle, the ladle needs to be placed as close to the container as possible. During pouring, the ladle is prone to unstable rotation, causing the molten steel to fall to the ground due to the gradual change in angle. Patent announcement number CN217070729U discloses a utility model patent for a hoisting ladle with a dumping structure, comprising: a fixed seat, two hydraulic telescopic rods connected to the top surface of the fixed seat, and a The ladle body is positioned between two hydraulic telescopic rods. Mounting blocks are removably connected to both outer walls of the ladle body. A rotating rod is connected to one end of the mounting block distal from the ladle body, and a positioning block is connected to the other end of the rotating rod. A clamping assembly is provided between the rotating rod and the hydraulic telescopic rod. The clamping assembly comprises a mounting frame connected to the outer walls of the hydraulic telescopic rods, a bidirectional lead screw rotatably connected between two lateral inner walls of the mounting frame, and two sleeves threadedly mounted around the outer periphery of the bidirectional lead screw. Each sleeve has a clamping block connected to the outer walls of the two sleeves for clamping the positioning blocks. This hoisting ladle with a tilting mechanism offers a simple structure and a long service life. However, directly raising and lowering the ladle can lead to unstable lifting and lowering due to sloshing of the liquid within the ladle. Furthermore, the two sides cannot rotate synchronously during tilting. If the rotation frequencies of the two sides are inconsistent, molten steel can easily spill and burn the operator. There is no limit on the rotation angle of the ladle during tilting, and as the molten steel decreases, the rotation angle of the ladle can easily shift during tilting. Utility Model Content
