The two limit blocks 105 correspond to the two side blocks 104 one by one, and are used to limit the rotation direction of the ladle 102, so that the ladle 102 can only be rotated and tilted toward one side of the blocking rod 108 to pour out the molten iron. The hanger 101 is U-shaped, with a hanging ring on the top and two bottoms on both sides. The connecting plate 106 is used for rotatably mounting the rotating rod 107, and a blocking rod 108 is installed at the end of the two rotating rods 107.

When the molten iron ladle 102 rotates and tilts to contact with the baffle 108 during hoisting, the tilt angle of the molten iron ladle 102 at this time is a dangerous angle. The metal rod 113 will rotate synchronously with the molten iron ladle 102. During the hoisting process of the molten iron ladle 102, the molten iron ladle 102 2 is kept vertical. When the rotating mechanism 103 is damaged, the ladle 102 will tilt toward the blocking rod 108. When the ladle 102 rotates and tilts to contact the blocking rod 108, the ladle 102 will be blocked by the blocking rod 108 and cannot continue to tilt.

By rotating the hand wheel, the iron ladle 102 can be driven to rotate. If the hand wheel is not rotated, the iron ladle 102 is locked by the worm gear and no longer rotates. The two limit blocks 105 correspond to the two side blocks 104 one by one, and are used to limit the rotation direction of the iron ladle 102, so that the iron ladle 102 can only be rotated and tilted toward one side of the baffle 108 to pour out the molten iron.

When the ladle 102 is rotated and tilted to contact with the blocking rod 108 during lifting, the tilt angle of the ladle 102 at this time is a dangerous angle; during the lifting of the ladle 102, the ladle 102 is kept vertical. When the rotating mechanism 103 is damaged, the ladle 102 will tilt toward the blocking rod 108. When the ladle 102 is rotated and tilted to contact with the blocking rod 108, the ladle 102 will be blocked by the blocking rod 108 and cannot continue to tilt. At the same time, the metal rod 113 will just rotate to contact with the iron sheet 112.

It may be unstable if only two steel wire ropes support the two connectors 116, thereby supporting the two rotating rods 107 and finally supporting the blocking rod 108. When the rotating mechanism 103 is damaged and the ladle 102 tilts suddenly, it will directly hit the blocking rod 108, which may cause the steel wire rope to break. Therefore, the reinforcing assembly 301 is arranged to further assist in supporting the blocking rod 108.

It may not be stable enough. When the rotating mechanism 103 is damaged and the ladle 102 suddenly tilts, it will directly hit the blocking rod 108, which may cause the steel wire rope to break. Therefore, the reinforcing component 301 is provided to further assist in supporting the blocking rod 108.
