CN202379588U - Special suspension bracket for small furnace lid of electric furnace - Google Patents

Abstract

The utility model discloses a special suspension bracket for a small furnace lid of an electric furnace. The special suspension bracket comprises a bracket body which is I-type; a flying ring is mounted at the center of the top surface of a main cross beam; two auxiliary cross beams fixedly connected to two ends of the top surface of the main cross beam are perpendicular to the main cross beam; and a chain is mounted under each of the bottom surfaces of the two ends of each auxiliary cross beam. When the special suspension bracket is used for replace the small furnace lid, an electrode arm is raised, the special suspension bracket is hung on a travelling crane, the suspension bracket is sleeved on an electrode cross arm, and lifting of the travelling crane and the electrode arm are carried out synchronously so as to realize dismounting and mounting of the small furnace lid, and the use is convenient.

Description

Special hanger for electric furnace small furnace cover

technical field

The utility model relates to a special hanger for a small furnace cover of an electric furnace.

Background technique

There is no special lifting device for the small furnace cover of the electric furnace. When replacing the small furnace cover, the conical sleeve of the large furnace cover must be disengaged first, and the single swing door frame is used. Finally, the small furnace cover must be disassembled by driving a chain. The main problem is that it takes about 40 minutes to hoist the small furnace cover, and it takes about 3 hours for the conical sleeve of the large furnace cover to be separated from the single-swing door frame, which seriously affects the maintenance efficiency.

Contents of the invention

The purpose of the utility model is to provide a special hanger for the small furnace cover of the electric furnace, which can quickly lift and replace the small furnace cover of the electric furnace, and saves trouble and labor in use.

The purpose of this utility model is achieved in this way, a special hanger for the small furnace cover of the electric furnace, including a frame body, the frame body is I-shaped, and the middle part of the top surface of the main beam of the frame body is installed with a suspension ring, which is fixedly connected to the top surface of the main beam The two sub-beams at the two ends are all perpendicular to the main beam, and a chain is respectively installed under the bottom surfaces of both ends of each sub-beam.

When the utility model is used to replace the small furnace cover, it is only necessary to raise the electrode arm, hang the special sling on the crane, put the sling on the electrode cross arm, and operate the crane and the electrode lifting synchronously to realize the removal and installation of the small furnace cover. , easy to use. By adopting the utility model, the replacement and maintenance time of the small furnace cover is reduced from 4 hours to about 1 hour, and the annual maintenance time is saved by 135 hours. It effectively reduces the load of small furnace cover replacement and maintenance, improves the efficiency of maintenance operations and equipment productivity, and reduces equipment maintenance costs and labor intensity of employees.

Description of drawings

The utility model will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a three-dimensional structure schematic diagram of the present utility model.

Detailed ways

A special hanger for the small furnace cover of an electric furnace, as shown in Figure 1, includes a frame body, the frame body is I-shaped, and the middle part of the top surface of the main beam 2 of the frame body is installed with a suspension ring 1, which is fixedly connected to the two ends of the top surface of the main beam Two auxiliary crossbeams 3 are all perpendicular to the main crossbeam 2, and a chain 4 is respectively installed under the bottom surfaces of both ends of each auxiliary crossbeam 3. When the utility model is used to replace the small furnace cover, it is only necessary to raise the electrode arm, hang the special sling on the crane, put the sling on the electrode cross arm, and operate the crane and the electrode lifting synchronously to realize the removal and installation of the small furnace cover. , easy to use.
