JPH06212158A - Apparatus for supporting oven-top brick during hot repair of brick work in coke oven chamber - Google Patents

Abstract

PURPOSE:To prevent the bending of an oven-top brick structure due to the traveling load of a charging car. CONSTITUTION:The apparatus supports oven-top bricks 7 and comprises a stand 5 for supporting a rail of a charging car and independent supporting beams 2, 3. The apparatus enables traveling of a moving machine on a coke oven even when the brick work in a coke oven chamber is under hot repair, preventing production troubles due to the repair work, decreasing the slacking of supporting bricks or occurrence of joint crack, and improving tightness of sealing the chamber wall after the repair.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rooftop brick support device for hot repair of a coke oven carbonization chamber.

[0002]

2. Description of the Related Art In a conventional furnace top brick support device for hot repair work of a coke oven carbonization chamber, as shown in FIG. 5, a roof top brick (not shown) of a non-repair combustion chamber is sandwiched between repair combustion chambers. The cross stay 2 supported by (No.) is supported. A suspension bolt 6 for supporting the furnace top brick of the repair combustion chamber is attached to the cross stay 2. When the rail of the charging vehicle running on the furnace is within the setting range of the cross stay 2, remove the charging vehicle rail and the rail platform as shown in FIG. It was necessary to dig and install the cross stay 2 or to join the cross stay 2 to the rail base as shown in FIG.

[0003]

As described above, in the furnace top brick supporting device according to the prior art, in the case of FIG. 6 (a), the structural strength of the furnace top brick is increased by largely excavating the furnace top brick. In addition, in the case of FIG. 6 (b), the deflection of the rail base due to the moving load of the charging vehicle causes the cross stay 2
As a result, the hanging bolt 6 moves up and down every time the charging vehicle passes through, causing structural deterioration of the furnace top brick and, in the worst case, loosening of joints on the furnace wall of the repair section.

[0004]

[Means for Solving the Problems] As a result of intensive development, the inventors of the present invention should solve the above problems. As a result, a rail support for a charging vehicle and an independent support girder are provided to support a rooftop brick. By doing so, it is intended to prevent the bending of the furnace top brick structure due to the moving load of the charging vehicle. The gist of the invention is to provide a charging vehicle rail support for preventing the bending of the furnace top brick structure due to the moving load of the charging vehicle in hot repair by the boring method of the coke oven carbonization chamber. , A furnace top brick support device in a hot repair of a carbonization chamber, characterized in that an independent support girder is provided to support the furnace top brick.

[0005]

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a sectional view in which a reinforcing support girder is provided in a repair combustion chamber according to the present invention. As shown in FIG. 1 (a), support girders 2 and 3 for supporting the furnace top brick are installed independently of the charging vehicle rail 1 and the rail platform 5. The support girders 2 and 3 are also independent of the cross tie rod A.

As described above, by providing the charging vehicle rail support and the independent reinforcing support girder, the bending of the furnace top brick structure due to the moving load of the charging vehicle is prevented. Reference numeral 8 is a combustion chamber, and 9 is a brick support hardware. FIG. 1 (b) is an enlarged view of the cross tie rod A portion, and the cross tie rod 18 is a temporary tie rod 1 to be added for repair.
It is joined with 0. This is a tie rod that is provided to create a step in the height direction of the cross tie rod because the height of the furnace top brick differs between the portion that is not repaired, such as the furnace end, and the portion that is excavated for repairing.

FIG. 2 is a plan view of the support structure according to the present invention of FIG. FIG. 2 is a diagram showing an example of a supporting structure for repairing two kilns. Support girders 2 and 3 separate from the loading vehicle rail and rail platform 1
Suspending bolt support beams 11 and 12 are respectively disposed on the column and fixed by a girder support base 13. Reference numeral 14 is a coal charging hole. FIG. 3 is a side view of the support structure according to the present invention in FIG. It has a structure in which the reinforcing support girder 3 is hoisted by hoisting bolts 6 for tightening the entire coke oven in the furnace height direction. Reference numeral 15 is a carbonization chamber. FIG. 4 is a view showing a cross-sectional structure of the charging vehicle rail support from the view B of FIG. The replacement range of the replacement rail 16 and the charging vehicle rail support 5 is shown. That is, it shows the range of rail replacement and the range of replacement of the loaded vehicle rail support. Further, reference numeral 17 indicates a rail joint portion when the rail is replaced.

As described above, by providing the reinforcing girder independent of the conventional support structure, it is possible to suppress the occurrence of cracks in the brick joint breakage due to the bending due to the influence of the disturbance load during the operation, and the operation is continued. However, it is possible to stably support the rooftop bricks in a steady state.

[0009]

As described above, according to the present invention, the traveling machine of the furnace moving machine can be operated even during the hot repair work, the production trouble due to the work can be avoided, and the supporting bricks during the repair work are also prevented. And the occurrence of joint cracks are reduced, and the surface wall sealing property after repair is improved, which is an extremely excellent effect.
