。However, since coal carbonization is indirect heating through the side walls of brickwork, long-term use may cause coke to fuse with the bricks, collapse of the brickwork side walls, or damage the side walls when taken out of the kiln. Therefore, the life of a normal reactor is said to be about 20 years.

がない。"Structure of the Invention" (Means for Solving the Problem) In order to achieve the above-mentioned object, the present inventors installed a rack in a position near the center of the boom in the length direction of the boom with relatively little temperature change. Each rack is fixed to the upper surface and adjacent to the rack is connected and fixed by bolts to the battens on both sides, while rack mounting brackets having horizontal elongated holes fixed to the boom and formed in the rack are provided. This paper proposes a coke oven melting repair device characterized in that a rack is mounted on the upper surface of the boom by overlapping horizontal long holes and tightening bolts. Since the thermal spray repair apparatus of the present invention has a structure that allows heat to escape, damage to the boom or rank will not occur.

膨張によるブームの破損もしくはラックの破損が生ずる
ことのないような配慮をしたところに特徴がある。(Function) The main part of the thermal spray repair apparatus of the present invention relates to a mounting mechanism for a hook for sending a boom for hot repair into a furnace. A distinctive feature is that care has been taken to prevent damage to the boom or rack due to thermal expansion of the rack attached to the top of the water-cooled boom.
本発明においては、
■ ラックを一本の金属製品とせず、分割ランクとして
熱膨張もしくは収縮による影古を少なくした。In the present invention, (1) the rack is not made of a single metal product, but is divided into ranks to reduce the effects of thermal expansion or contraction.
■ ブームの長さ方向で中心部に近い比較的温度変化の
少ない位置の中心う・2りをブームに固定し、該ラック
に隣接する先端部側もしくは基部側のラックは夫々目板
をもって連結せしめたので、ラック間の間隙が広がるこ
とのないように配慮した。■ Fix the center ridge to the boom at a position near the center in the length direction of the boom where there is relatively little temperature change, and connect the racks on the tip or base side adjacent to the rack with a batten, respectively. Therefore, care was taken to prevent the gaps between racks from widening.
■ ブームに固定して設けたう・ツク取り付け金具と分
割ラックには夫々同一高さ水平方向の長孔を設けて重ね

ので、形状を損うことがないように考慮しである。■ The U-TSUKU mounting bracket fixed to the boom and the split rack each have long horizontal holes at the same height and are bolted together, so the rank is in close contact with the boom in the vertical direction. The structure was designed so that it could be freely expanded and contracted in the horizontal direction (longitudinal direction) using elongated holes, so that the shape would not be damaged.

。(Example) FIG. 2 is a plan view showing an outline of a boom to which the device of the present invention is attached. A rack 2 is disposed on the top surface of a water-cooled boom 1 that feeds repair materials for repairing a coke oven to a burner at the tip, extending over almost the entire length of the boom. (Only a portion is shown in the drawing). This boom is moved forward and backward by the above-mentioned rack 2 meshing with a spur gear 5 driven by a hydraulic motor 4 provided on a support frame 3 and a coaxial pinion 6. A pair of guide rollers 7 at the front and rear are used to move the boom forward and backward. FIG. 3 is a side view schematically showing the part to which the rack of the present invention is attached, and one end of the hydraulic cylinder 10 is attached to the lower side 9 of the support frame that supports the boom placed on the pedestal 8 of the truck. The boom is fixed to the shaft, and the other end is fixed to the trolley, allowing the inclination angle of the boom to be changed arbitrarily.

しである。The position and size of the rank attached to the boom as well as the forward and backward movement mechanism can be understood from FIGS. 2 and 3 mentioned above. However, since the drawings are complicated, the rank attachment mechanism, which is the main part of the present invention, is omitted in both drawings.

接により固定されている。FIG. 1 is a side view showing the main parts of the present invention (however, the upper tooth pattern of the rack is omitted). The center rack 2a is a rank located at a position near the longitudinal center of the boom with relatively little temperature change, and is fixed to a rack fixing fitting 20 fixed to the upper surface of the boom 1 with bolts 21. The respective divided racks 2b adjacent to the rank 2a are horizontally connected from both sides by battens 22 and bolts 21, but the battens 22 are only in contact with the boom and are not fixed. The split rack 2b is provided with elongated holes 24 at two places in the horizontal direction, and is overlapped with the horizontal elongated holes 24 of the same height provided in the rack mounting fittings 23, and is fastened with bolts 21 and mounted on the boom. However, the installed rack can freely expand and contract in the length direction due to the elongated holes, so there will be no damage to the boom or rack. The rank attachment fittings 23 are fixed to the upper surface of the boom by welding.
