Automatic picking pothook for metallurgical sling and hot metal tank tipping sling for metallurgical sling

Abstract

The invention discloses an automatic picking pothook for a metallurgical sling. The automatic picking pothook comprises a connecting rod (1) and an eccentric hook (6), wherein the connecting rod (1) is used for being connected with the secondary hook of the metallurgical sling, and the outline of the connecting rod (1) is matched with that of a hot metal tank; a hooking hinge pin (4) hooked to thesecondary hook of the metallurgical sling is arranged in the connecting hole of a first connecting rod; a mounting hinge pin (5) is arranged in the connecting hole of a second connecting rod; the eccentric hook (6) is used for realized being hooked to the hot metal tank; an eccentric hook connecting hole (7) matched and connected with the mounting hinge pin in an inserting manner is formed in theupper part of the eccentric hook; a bent hook (8) for hooking the hot metal tank is arranged on one side of the eccentric hook connecting hole and on the eccentric hook; a counterweight part (9) is arranged on the other side of the eccentric hook connecting hole and on the eccentric hook; and through matching of the eccentric hook connecting hole and the mounting hinge pin, the eccentric hook isrotatably arranged on the connecting rod. The automatic picking pothook lowers the labor intensity of a worker, saves the manpower resources, improves the onsite operating efficiency and reduces the maintaining frequency.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, and more specifically relates to an automatic lifting hook for metallurgical cranes and a tilting hoist for molten iron tanks for metallurgical cranes. Background technique [0002] Metallurgical hoisting, lifting and transporting molten iron tanks, tipping and mixing iron is an indispensable process in the steelmaking production system, which has a decisive impact on the production cost and smelting rhythm of steelmaking. After the main hook of the metallurgical crane lifts the molten iron tank, it is necessary to use the auxiliary hook to hang the bottom pin of the molten iron tank. After the molten iron tank is lifted to the designated position of the electric furnace or converter, the main hook needs to fall to a certain position, and the auxiliary hook lifts the molten iron tank The bottom is mixed with molten iron into the furnace. After mixing the molten iron in the molten...

AI Technical Summary

Problems solved by technology

[0006] When the pin shaft hook at the bottom of the water tank is manually removed and hung, it is in direct contact with the molten iron tank, and under it, if the vehicle fails and the molten iron tank slides, it will cause smashing accidents or even casualties

People stand next to the molten iron tank to work. If the red slag falls or the molten iron splashes out, it will cause burns. At the same time, manual removal of the hook is easy to squeeze the hands, which does not meet the safety operation standard.

[0007] 2. Occupying a lot of human resources and low operating efficiency

[0008] Using traditional conventional spreaders requires at least two people to work together, which takes up a lot of human resources and causes tension in the posts.

At the same time, the manual removal of the hook is performed once every half an hour on average, and it takes 3-5 minutes each time, which is labor-intensive and low-efficiency

[0009] 3. High maintenance cost

[0010] The small anchor hooks used for picking and hanging are easy to deform and wear, and the wire rope is easy to break, which requires frequent replacement, high maintenance costs, and frequent repairs
