Rotary combined lifting sling for metallurgy

Abstract

The invention discloses a rotary combined lifting sling for metallurgy. The combined lifting sling comprises a balance beam, wherein a ball joint is arranged in the balance beam, a ball pin of the ball joint extends out of the balance beam to be connected with a lifting hook, a lifting hook rotating motor is arranged on the balance beam, an output end of the lifting hook rotating motor is connected with a hook handle of the lifting hook through a bevel gear pair, and a rotary locking mechanism is arranged between the lifting hook and the balance beam. The combined lifting sling has the benefits that after the lifting sling lifts a weight to an assigned place, the lifting hook rotating motor can drive the lifting hook to rotate to adjust the angle of the lifting sling, and discharging is facilitated; the rotary locking mechanism is arranged between the lifting hook and the balance beam, so that the lifting hook can be prevented from swinging in the lifting process by the aid of the rotary locking mechanism, and the lifting safety is improved.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a rotatable combined spreader for metallurgy. Background technique [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 l...
