Abstract

The invention discloses a steel ladle cover. The steel ladle cover comprises a body and a lifting lug, and also comprises a lifting ring and a lifting chain device, wherein the lifting chain device comprises the lifting ring, an upper shaft, an intermediate shaft, a lower shaft, a plurality of lifting chains and plates, the lifting ring, the upper shaft, the intermediate shaft and the lower shaft are sequentially connected from top to bottom through two plates, the lifting ring is arranged at the top, the upper shaft is arranged below the lifting ring and seated on a hook of a steel ladle capping device, the intermediate shaft is positioned below the upper shaft, the lower shaft is positioned at the bottom, the lower ends of the plurality of lifting chains are respectively tied on the lifting lug, and the upper ends of the plurality of lifting chains are arranged on the lower shaft in a concentrated way. According to the invention, as the steel ladle cover is additionally provided with the lifting chain device and a lifting shaft of the existing steel ladle cover is replaced by the lifting ring, the connection between the lifting ring and the lifting chain device is facilitated, and the structure is simplified. When the steel ladle cover needs to be replaced, the whole steel ladle cover can be lifted up only by using a lifting hook of a crane for lifting up the lifting ring on the lifting chain device, so that the steel ladle cover is convenient to use, and can be used for improving the working efficiency and ensuring the continuity of production.

Description

A kind of ladle lid

Technical field

The present invention relates to a kind of steelmaking equipment, particularly a kind of ladle lid.

Background technology

The ladle lid is to be suspended from the steel ladle top by the ladle stamp device, the molten steel in the ladle of below is played the equipment of insulation effect.The equipment of accepting ladle is ladle turret, and it can accept two ladles, and casting is changed in revolution, guarantees the continuity of casting.This just makes as long as in the ladle molten steel is arranged, all needs the ladle lid above it to the molten steel insulation in the ladle by the state that ladle is in basically always has molten steel.Because the ladle lid is positioned at molten steel top and close together for a long time, so loss is bigger, it is higher to change frequency.

As shown in Figure 1; Existing ladle lid comprises body and hanging axis, and covers the diverse location hanger of evenly burn-oning at ladle, when needs are changed the ladle lid; The ladle lid is turned to the position of operating personnel's handled easily by the ladle stamp device; Earlier lifting rope is tethered on the hanger of ladle lid by manual work, again lifting rope is fastened on the suspension hook of crane, whole ladle lid is hung away.Because the ladle lid is positioned at the molten steel top for a long time, so ladle lid self-temperature is very high, work under bad environment; The volume of ladle lid own is bigger, and operation needs on ladle turret, to carry out, and exercisable space is limited, and manually-operated is got up very inconvenient, has potential safety hazard, and operating efficiency is low.

Summary of the invention

For solving the problems referred to above that prior art exists, the present invention will design a kind of ladle lid of realizing unmanned replacing, increasing work efficiency, stop potential safety hazard.

To achieve these goals, technical scheme of the present invention is following: a kind of ladle lid, comprise body and hanger, and also comprise suspension ring and chain sling device, described chain sling device comprises hoisting ring, upper shaft, jackshaft, lower shaft, chain sling and plate; Described hoisting ring, upper shaft, jackshaft and lower shaft from top to bottom are connected through two boards successively, and the top is a hoisting ring, and crane is sling when being used to change the ladle lid, is in free state at ordinary times; The below of hoisting ring is a upper shaft, the top axle bed on the hook of ladle stamp device, to be used for work outstanding with ladle lid through the ladle stamp device; Described jackshaft is positioned at the below of upper shaft, is used for the suspension ring of ladle lid are sling, and ladle lid body is suspended from the chain sling device; Described lower shaft is positioned at below, and the chain sling that is used to sling makes it be in tensioned state always, guarantees the balance that the ladle lid is sling; Described chain sling has many, its lower end fasten respectively on the hanger, its upper end install concentratedly on lower shaft.

Compared with prior art, the present invention has following beneficial effect:

1, because the present invention covers at ladle and has increased the chain sling device, and the hanging axis that will have the ladle lid now changes suspension ring into, make things convenient for being connected of suspension ring and chain sling device like this, simplify the structure.The present invention has abandoned the design concept that lifting need be adorned lifting rope at present, makes equipment and lifting articles for use realize integrated.

2, hang by the ladle stamp device during ladle lid work of the present invention; When needs were changed the ladle lid, the hoisting ring that only needs the suspension hook of crane to sling on the chain sling device can hang away whole ladle lid, and was easy to use; Increase work efficiency, guaranteed the continuity of producing.

3, because chain sling of the present invention and ladle lid are incorporate structures, when needing to change the ladle lid, need not artificial binding lifting rope, realized unmanned replacing, stopped potential safety hazard.

Description of drawings

3 in the total accompanying drawing of the present invention, wherein:

Fig. 1 is the structural representation of existing ladle lid.

Fig. 2 is the structural representation of ladle lid of the present invention.

Fig. 3 is the A-A view of Fig. 2.

Among the figure: 1. body, 2. chain sling device, 3. ladle stamp device, 4. suspension ring, 5. hanger, 6. hanging axis, 7. hoisting ring, 8. upper shaft, 9. jackshaft, 10. lower shaft, 11. chain slings, 12. plates.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described further.

Fig. 1 is the structural representation of existing ladle lid.When working at ordinary times, the sling hanging axis 6 of ladle lid of ladle stamp device 3 is suspended from the molten steel it; When needs are changed, need ladle stamp device 3 that ladle is covered the position that forwards people's handled easily to, earlier lifting rope is tethered on the hanger 5 of ladle lid by manual work, again lifting rope is fastened on the suspension hook of crane, whole ladle lid is hung away.

Shown in Fig. 2-3, a kind of ladle lid comprises body 1 and hanger 5, also comprises suspension ring 4 and chain sling device 2, and described chain sling device 2 comprises hoisting ring 7, upper shaft 8, jackshaft 9, lower shaft 10, chain sling 11 and plate 12; Described hoisting ring 7, upper shaft 8, jackshaft 9 from top to bottom are connected through two boards 12 with lower shaft 10 successively, and the top is a hoisting ring 7, and crane is sling when being used to change the ladle lid, is in free state at ordinary times; The below of hoisting ring 7 is a upper shaft 8,8 of upper shaft on the hook of ladle stamp device 3, to be used for work outstanding with the ladle lid through ladle stamp device 3; Described jackshaft 9 is positioned at the below of upper shaft 8, is used for the suspension ring 4 of ladle lid are sling, and ladle lid body 1 is suspended from the chain sling device 2; Described lower shaft 10 is positioned at below, and the chain sling 11 that is used to sling makes it be in tensioned state always, guarantees the balance that the ladle lid is sling; Described chain sling 11 has many, its lower end fasten respectively on the hanger 5, its upper end install concentratedly on lower shaft 10.

The course of work of the present invention is following: ladle lid body 1 hangs on the jackshaft 9 of chain sling device 2 through suspension ring 4.During work, 8 of the upper shaft of chain sling device 2 are suspended from the molten steel ladle lid on the hook of ladle stamp device 3; When needs are changed, only need the suspension hook of the crane hoisting ring 7 of slinging can whole ladle lid be hung away.Wherein the chain sling 11 of chain sling device 2 is tethered between ladle lid body 1 and the chain sling device 2, is in tensioned state always, has guaranteed the balance that the ladle lid is sling.
