Problems solved by technology

However, the steel ladles used in metallurgical casting today often adopt the traditional cylindrical design. During the overturning process of the traditional steel ladle, the running track of the auxiliary hook of the casting crane is an arc. If the molten steel is to be poured stably, the auxiliary hook of the casting crane

Embodiment Construction

[0017] In order to have a clearer understanding of the technical content of the present invention, specific implementations are specifically described in detail.

[0018] The single-trolley double-girder casting crane with a single-cart and double-girder casting crane with a main hook lifts the hemispherical ladle to the position where molten steel needs to be poured. When the auxiliary hook is not hooked, the auxiliary hook hanger is tilted outside the chain or wire rope groove. In the groove on the top of the stretch rib, it is convenient for the auxiliary hook to hook. When the ladle needs to be tipped over, the main hook is hung on the main hook hanging point and remains still, and the auxiliary hook is gradually lifted after being hung on the auxiliary hook spreader, and the chain or wire rope is used to drive the ladle to rotate to complete the dumping of molten steel or cleaning of steel slag. Since the ladle rotates around the trunnion, and the hemispherical pot-shaped...

Abstract

The invention relates to a single-trolley and double-beam ladle crane with a non-translating cast secondary hook, and belongs to the field of heavy devices for metallurgy and casting innovation. The single-trolley and double-beam ladle crane with the non-translating cast secondary hook is provided with only two main beams, a main lifting mechanism and an auxiliary lifting mechanism are arranged onthe same trolley frame and are used together with a hemispherical pot-shaped ladle, the secondary hook only needs to be vertically lifted in order to complete molten steel overturning and slag cleaning, and the secondary hook and an auxiliary lifting driving mechanism do not need to move horizontally. Compared with traditional ladle cranes, the single-trolley and double-beam ladle crane has the advantages of construction simplification, unlimitation by the tonnage size, saving of the manufacturing and maintenance cost, avoiding of the slippage of secondary trolley wheels during double-dolly casting, enhancement of the stability of molten steel pouring, facilitation of the intelligentization of high-precision constant flow casting of the ladle crane, and facilitation of improvement of thequality of hot continuous rolling and casting products.

Description

technical field [0001] The invention relates to a single-carriage double-girder casting crane with a non-translational casting auxiliary hook, which is mainly used in iron and steel smelting and molten steel casting, and belongs to the category of high-precision intelligent control metallurgy and casting innovative heavy equipment. Background technique [0002] The rapid development of the domestic economy and the urgent need for infrastructure construction have promoted the improvement of my country's steel production and performance. Casting crane pouring molten steel pouring has an extremely important effect on the properties of steel. During the tipping process of the ladle, the operator only realizes the dumping of the ladle through an indirect screen, and the rotational displacement of the ladle per unit time cannot be precisely controlled; moreover, in this process, the cooperative work of ground guidance personnel is often required , to complete the entire pouring p...
