Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blast furnace furnace dismantling and assembling apparatus for disassembling or assembling a furnace body of a blast furnace. Note that the “partial mantel” used below is used to include both an iron shell alone and an iron shell integrated with a stave (or stove cooler), brick, and the like.

[0002]

2. Description of the Related Art Conventionally, a dismantling and assembling apparatus for a blast furnace furnace for disassembling or assembling a furnace body of a blast furnace uses a lifting machine (generally a traveling furnace top outrigger crane) attached to a furnace tower for installation. It is known to dismantle or assemble a furnace body.

On the other hand, a furnace body is divided into, for example, five large blocks (top mantel, upper shaft mantel, lower shaft mantel, Bosch mantel, and Haas mantel), and each block is lifted from the furnace bottom by an elevating facility provided in a furnace body turret. What is taken in (for example, Japanese Unexamined Patent Publication No. Hei 9-143521) or what is obtained by dividing a furnace body into a plurality of blocks and carrying out or carrying in each of the blocks from a working floor through a bogie using a hollow hydraulic jack provided in a furnace body tower. (For example, see JP-A-53-8
7906, JP-A-53-87907, etc.) are known.

[0004]

However, the hoisting machine (furnace outrigger crane) attached to the rooftop turret usually has a lifting capacity of about 60 to 200 tons, and the furnace body has a total weight of several thousand tons. Even when a ring-shaped mantel is divided into a ring shape in the horizontal direction, it usually has a scale of several hundred tons when the stave is attached. For this reason, dismantling or assembling (installation) was performed by dividing the furnace body into strip-shaped pieces.
It was not economic.

On the other hand, when the furnace body is divided into five large blocks and then carried out or carried in, the weight of the blocks themselves becomes extremely large, and extremely large-scale temporary installation for lifting, hanging, etc. is required, and the area around the furnace bottom is required. Requires a lot of work space,
It was not a general-purpose device due to the spatial structure of the entire blast furnace structure and its surroundings.

[0006] Further, when the furnace body is divided into a plurality of blocks and is carried out or carried in through a bogie at an operating floor level, a gap in the height direction between the operating floor level and an annular pipe near two beds is small. The height is limited by the effective height from the top of the trolley, and the height of each block cannot be increased. In order to avoid this, it is necessary to remove the annular pipe, and a large amount of labor is required because a work for restoring the annular pipe also occurs.

The disassembly and assembly of the blast furnace body were completely the same in the mantel assembly and installation when a blast furnace was newly installed.

An object of the present invention is to provide a dismantling and assembling apparatus for a blast furnace furnace body, in which the degree of freedom of movement of a partial mantel during dismantling and assembling is large and the spatial restriction is small. Furthermore, the dismantling and assembly work is easy and the construction period can be shortened.
It is economical.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to a partial mantel obtained by dividing a blast furnace furnace body into a plurality of parts, and the partial mantels are sequentially dismantled from the furnace body or sequentially assembled. In the dismantling and assembling apparatus for the blast furnace furnace body to be assembled in the above, the receiving beam provided between the inside and the outside of the furnace tower of the blast furnace, and the partial mantel is movable on the receiving beam in a substantially horizontal direction. A moving unit which is provided and is capable of moving the partial mantel in a substantially vertical direction, the moving unit includes a bridging member having a predetermined length, and a vertical moving means for raising and lowering the bridging member in a substantially vertical direction. And a suspending means attached to the bridging member and capable of suspending the partial mantel.

[0010] Since the receiving beam is provided between the inside and the outside of the furnace tower of the blast furnace, the moving unit travels on the receiving beam between the inside and the outside of the furnace tower and moves the partial mantel. It can be moved in a substantially horizontal direction. Furthermore, since the suspension means is attached to the bridging member, the movable unit can suspend the partial mantel. Furthermore, since the vertical moving means can raise and lower the bridging member in the substantially vertical direction, the partial mantel suspended by the bridging means on the bridging member or placed on the bridging member via the bracket in a substantially vertical direction. Can be raised and lowered. Therefore, the mobile unit
The partial mantel can be relatively freely moved in a substantially horizontal direction and a substantially vertical direction.

Further, in the dismantling and assembling apparatus for a blast furnace furnace body, the moving unit is formed in a gate shape by bridging the bridging member between the two vertical moving means, and the vertical moving means is provided. Can be raised and lowered in multiple stages. The dismantling and assembling device for the blast furnace furnace body formed in a gate shape stabilizes the partial mantel by raising and lowering the two vertical moving means on both sides of the moving unit in addition to the operation of the disassembling and assembling device for the blast furnace body described above. Since the vertical maneuver can be raised and lowered in a substantially vertical direction and the vertical moving means can be raised and lowered in multiple stages, the partial mantel can be moved to a required height position, and disassembly and assembly are facilitated.

In any one of the above dismantling and assembling apparatuses for a blast furnace furnace, the suspending means can lift and suspend the partial mantel.
A dismantling and assembling apparatus for a blast furnace furnace body provided with a suspending means capable of lifting and suspending is provided. So that the partial mantel can be suspended and moved to a position below the bridging member or can be lifted and moved from a position below the bridging member, and the degree of freedom of the partial mantel in the vertical direction can be increased. growing.

Therefore, the apparatus for dismantling and assembling a blast furnace body according to the present invention has a high degree of freedom of movement of the partial mantel during dismantling and assembling, and reduces spatial restrictions. Further, the disassembly and assembling work is easy, the construction period can be shortened, and it is efficient and economical.
