Description

A crane hook rotating alignment device

technical field

The utility model relates to the technical field of lifting devices, in particular to a rotary aligning device for a crane coupler.

Background technique

The crane is an important lifting equipment in the production workshop. When it lifts heavy objects, it is often necessary to adjust the direction of the heavy objects. For objects with light weight, the direction of the object can be adjusted by manually rotating the object; if it is a large object with a large weight, it is laborious and time-consuming to adjust the direction manually. Especially in the scrap workshop of steel mills, the hoisted ladle cover is often about 7 tons, or even heavier. When the hot metal truck with the hot metal ladle enters the workshop, first lift the lid of the hot metal ladle, and then add scrap steel to the hot metal ladle. At this time, the on-site operator needs to use a 6-meter-long iron pipe to manually push the cover to find the appropriate angle, and then make sure that the cover is aligned with the molten iron ladle, and then cover the molten iron ladle cover on the molten iron truck. Alignment makes the angle accuracy low and requires repeated adjustment, and often hits the ladle mouth and causes the ladle mouth and the refractory material of the ladle to fall off, which affects the service life of the ladle and the ladle.
