[0002] One of the most commonly used tools when lifting heavy objects is the spreader. The hoisting system of cranes commonly used in the metallurgical industry is a steel wire rope plus a fixed gantry hook. It has a single structure and a single purpose. It is only used for lifting ladles. Directly lift the balance beam containing the movable pulley to lift the gantry hook connected to it for operation. Since this structure can only be used for lifting the ladle and cannot adjust the rotation after lifting to the designated place, there are many constraints in use. If The spreader can be adjusted and rotated. If it rotates during transportation, the molten steel may spill out and burn the workers underneath. Therefore, many factories generally use a spreader that cannot be adjusted to rotate to transport the ladle. many inconveniences

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0015] Such as Figure 1-4 As shown, a metallurgical combination hanger includes a balance beam 1, a ball joint 4 is arranged inside the balance beam 1, and a ball pin of the ball joint 4 protrudes from the balance beam 1 and is connected with a suspension hook 2. The hook 2 is provided with an anti-tripping ring 9, the upper end of the anti-tripping ring 9 is hinged with the hook handle of the suspension hook 2, and the lower end is locked on the head of the suspension hook 2. A rotation locking mechanism is provided between the hook 2 and the balance beam 1, the rotation locking mechanism includes a positioning pin 7 and a positioning seat 8, the upper end of the positioning pin 7 is hinged with the balance beam 1, and the positioning seat 8 Fixedly installed on the upper part of the hook handle of the hook 2, the positioning seat 8 is provided with ...

The invention discloses a combined lifting sling for metallurgy. The combined lifting sling comprises a balance beam, a spherical hinge is arranged in the balance beam, a ball pin of the spherical hinge extends out of the balance beam to be connected with a lifting hook, and a rotary locking mechanism is arranged between the lifting hook and the balance beam. The combined lifting sling has the benefits as follows: after the lifting sling lifts weights to a designated place, the angle of the lifting sling can be adjusted through rotation of the spherical hinge, and discharging is facilitated. The rotary locking mechanism is arranged between the lifting hook and the balance beam, the rotary locking mechanism can prevent the lifting hook from swinging during lifting, and the lifting safety isimproved.
