業を終了する。<Conventional technology> Conventionally, for example, brick lining work for converters has been carried out since 1983.
- As shown in No. 48549, magnesia-dolomite bricks on a pallet carried by a forklift were lowered to the hearth using the elevator in the furnace tower installed vertically in the converter. The bricks were further conveyed using a conveyor or the like, but in the end, a person held the bricks by hand and arranged them one after another on the hearth to form the -i-th and second layers. After the bricklaying of the hearth is completed, the bricks are stacked one after another from the bottom of the side wall on the inner circumferential surface of the converter to form the first and second layers along the circumference. Bricks are laid along the circumferential direction of the side wall of the surface, and after the bricklaying work for the entire side wall is completed, two layers of bricks are stacked in the same manner on the inner peripheral surface of the constricted part at the top of the converter. Brick lining work for the entire target area is completed.

目的とする。<Problems to be Solved by the Invention> Conventional magnesia-dolomite bricks have a cross section of 150 mtn square and a thickness of 270 mtn due to manufacturing press capacity, firing distortion, and manual handling weight during construction. ~
450m was the standard product. Therefore, the side wall thickness is 7
In the brick lining structure of a converter such as 30 to 810M, there is no choice but to use two layers of joint winding. However, when using two layers of seam wrapping, when the wear progresses and reaches the seam, there is a problem that the seam may fall off due to handling problems or chips. Therefore, in order to solve this problem, it is necessary to create a -F1 winding structure.However, if -H6 winding is used, conventional magnesia-dolomite bricks are fired at high temperatures, so they may warp, etc. According to the work regulations of the Industrial Safety and Health Act, the width of IEt taken by men over the age of 18 is limited to 55 to 5 or less.As a lining material for converters,
Compared to conventional magnesia-dolomite bricks,
Magnesia carbon bricks, which have excellent durability such as structural spall resistance and erosion resistance, are gaining popularity. Since this magnesia carbonaceous brick does not need to be fired during manufacture, it is easier to manufacture large (elongated) shapes as it does not suffer from firing distortion due to warping compared to conventional magnesia-dolomite fired products at high temperatures. The present invention uses bricks with a large (elongated) shape that exceeds the manual handling type specified in the Industrial Safety and Health Act to lining the inside of a large container such as a converter with a single layer ff1.
To provide a brick-building device for a large container, which can safely and quickly transport and build large bricks in a container without manual labor, in order to achieve tM.

Next, a support platform installed around the constructed tower that can be raised and lowered is lowered to a predetermined position. The swing guide rail is pre-attached to the lower part of the support base. The construction arm is then rotated along the guide rail to a predetermined work position. Once the construction arm is set at a predetermined position, fine adjustments are made by vertically extending or contracting the construction arm by a predetermined amount. Next, the construction arm is rotated in the elevation direction, the large brick is suctioned and gripped from the top and both sides using a vacuum pad, and while the brick is being gripped, the construction arm is rotated in the depression direction to position the bottom of the large container at a predetermined position. Carry it to the location and place the bricks there.

部に取付番プる。During the work of laying bricks at the bottom of a large container, the construction arm is moved along the guide rail as appropriate to make the work easier, and bricks are laid -WJ over the entire bottom of the large container. Once the bricklaying work for the entire bottom of the large container is completed, the work moves on to bricklaying the lower part of the side wall and the middle part of the sidewall of the large container. Similar to the bricklaying work at the bottom, in this work, the bricks are gripped from three sides with the bricks oriented laterally using the vacuum pad at the tip of the construction arm, and the bricks are successively laid on the side walls. Finally, when bricklaying the upper part of the side wall and the narrowing part of the large container, a guide rail and a construction arm that runs along the guide rail are installed from the bottom of the support platform that can be raised and lowered around the construction tower. Remove each. Next, attach the idle rail and construction arm dedicated to the upper part of the side wall and the throttle part to the upper part of the support base.

作業を終了する。That is, a guide rail is attached to the upper part of the support base, and a construction arm that runs along the guide rail is installed in an upright manner above the support base. With the support platform raised to a predetermined position and the construction arm located above the support platform set in the predetermined position, bricks are stacked one layer at a time on the upper side wall and constriction part of the large container via vacuum pads, respectively. In this way, the work is completed by piling up the bricks in one layer all over the inner wall of the large container.
