PROBLEM TO BE SOLVED: To provide a device for conveying bricks for repairing a combustion chamber brick of a coke oven, which improves repair operation efficiency by ensuring block masonry bricks disposed not only on a lower layer part of the bricks but also on an upper layer part thereof.SOLUTION: A device for conveying bricks for repairing a combustion chamber brick of a coke oven includes: a total of two in-pile beams 6 respectively secured to ceilings of a coke oven chamber located on both sides of the bricks; a total of two travel devices 7 respectively mounted movably along the in-pile beams 6; and a suspension device 8 suspended from the travel devices 7 so as to hold block masonry bricks 9.

Description

本発明は、コークス炉の燃焼室の煉瓦を補修するにあたって、炉外で耐火煉瓦を組み立てて成形したブロック体（以下、ブロック積み煉瓦という）をコークス炉内に搬入するための運搬装置（以下、煉瓦運搬装置という）に関するものである。   The present invention, when repairing bricks in the combustion chamber of the coke oven, a conveying device (hereinafter, referred to as block bricks) for carrying a block body (hereinafter referred to as a block brick) assembled by assembling refractory bricks outside the furnace into the coke oven. Brick transport device).

図５はコークス炉の要部を模式的に示す水平断面図であり、図６は煉瓦の例を模式的に示す斜視図である。
一般にコークス炉は、図５に示すように、石炭を乾留する炭化室２、燃料ガスを燃焼させる燃焼室１、燃焼排ガスの余熱を利用して燃料ガスや燃焼用空気を予め加熱する蓄熱室（図示せず）で構成され、燃焼室１と炭化室２は横方向に交互に配置される。つまり図６に示すように、互いに隣接する炭化室２を隔離する耐火煉瓦の煉瓦３の内部に燃焼室１が形成される。 FIG. 5 is a horizontal sectional view schematically showing the main part of the coke oven, and FIG. 6 is a perspective view schematically showing an example of a brick.
In general, as shown in FIG. 5, a coke oven has a carbonization chamber 2 for dry distillation of coal, a combustion chamber 1 for burning fuel gas, and a heat storage chamber for preheating fuel gas and combustion air using the residual heat of combustion exhaust gas ( The combustion chambers 1 and the carbonization chambers 2 are alternately arranged in the lateral direction. That is, as shown in FIG. 6, the combustion chamber 1 is formed inside the brick 3 of the refractory brick that separates the adjacent carbonization chambers 2.

そしてコークス炉の操業中に、炭化室２へ石炭を装入し、さらに燃焼室１で発生する燃焼熱によって乾留した後、得られたコークスを炭化室２から排出する作業が繰り返し行なわれる。その結果、耐火煉瓦で形成される煉瓦３が損耗し、燃焼室１から燃焼排ガスや未燃焼の燃料ガスが炭化室２内へ漏出するという問題が生じる。
そこで、燃焼室１の煉瓦を適宜補修しなければならないが、コークス炉の燃焼室１と炭化室２を全て停止して補修を行なうのはコークスの生産に支障を来す。したがって、コークス炉を操業しながら煉瓦３を補修する技術が種々検討されている。 During the operation of the coke oven, coal is charged into the carbonization chamber 2 and further subjected to dry distillation by the combustion heat generated in the combustion chamber 1, and then the obtained coke is discharged from the carbonization chamber 2 repeatedly. As a result, the brick 3 formed of refractory bricks is worn out, causing a problem that combustion exhaust gas or unburned fuel gas leaks from the combustion chamber 1 into the carbonization chamber 2.
Therefore, the bricks in the combustion chamber 1 must be repaired as appropriate. However, if all the combustion chambers 1 and the carbonization chamber 2 of the coke oven are stopped and repaired, the production of coke will be hindered. Therefore, various techniques for repairing the brick 3 while operating the coke oven have been studied.

たとえば特許文献１には、補修すべき煉瓦を解体し、さらに炉内から除去する一方で、煉瓦を構成する複数の積層部分を炉外にて耐火煉瓦を組み立てて成形し、得られたブロック積み煉瓦を炉内に搬入して煉瓦を補修する技術が開示されている。しかし特許文献１には、ブロック積み煉瓦を炉内に搬入する手段は具体的に開示されていない。
特許文献２には、図４に示すように、燃焼室の天井に設けられた覗き孔４に天井吊り金物５を設置し、その天井吊り金物５で燃焼室の天井に炉内ビーム６を固定し、さらに炉内ビーム６に沿って移動可能な走行装置７から吊り下げた吊り装置８を用いて炉内に補修用の煉瓦を搬入する技術が開示されている。したがって、炉外で成形したブロック積み煉瓦９を、この技術で炉内に搬入すれば、効率良く煉瓦の補修を行なうことができる。 For example, in Patent Document 1, a brick to be repaired is dismantled and removed from the inside of the furnace, while a plurality of laminated parts constituting the brick are assembled and molded outside the furnace to form a fire brick, and the resulting block stack is obtained. A technique for repairing a brick by carrying the brick into a furnace is disclosed. However, Patent Document 1 does not specifically disclose means for carrying block bricks into the furnace.
In Patent Document 2, as shown in FIG. 4, a ceiling hanger 5 is installed in a peephole 4 provided in the ceiling of the combustion chamber, and the in-furnace beam 6 is fixed to the ceiling of the combustion chamber by the ceiling hanger 5. In addition, a technique is disclosed in which bricks for repair are carried into the furnace using a suspension device 8 suspended from a traveling device 7 movable along the furnace beam 6. Accordingly, if the block brick 9 molded outside the furnace is carried into the furnace by this technique, the brick can be repaired efficiently.

しかし特許文献２に開示された技術は、補修すべき煉瓦の真上に炉内ビーム６や走行装置７が配置されるので、煉瓦の上層部に配置されるブロック積み煉瓦９を搬入する際には、吊り装置８が炉内ビーム６や走行装置７と干渉して、ブロック積み煉瓦９の搬入が極めて困難になる。そのため、煉瓦の上層部の補修は、炉内に耐火煉瓦を個別に持ち込んで人力で作業せざるを得ず、補修作業の効率低下を招く。   However, in the technique disclosed in Patent Document 2, since the in-furnace beam 6 and the traveling device 7 are disposed right above the brick to be repaired, when the block brick 9 placed in the upper layer portion of the brick is carried in. The suspension device 8 interferes with the in-furnace beam 6 and the traveling device 7, and it becomes very difficult to carry in the block brick 9. Therefore, the repair of the upper layer of the brick has to be carried out manually by bringing refractory bricks individually into the furnace, leading to a reduction in the efficiency of the repair work.

本発明は、燃焼室の煉瓦を補修するにあたって、煉瓦の下層部のみならず上層部に配置されるブロック積み煉瓦の搬入をも可能にして補修作業の効率向上を図る燃焼室煉瓦補修用の煉瓦運搬装置を提供することを目的とする。   The present invention relates to a brick for repairing a combustion chamber brick, which can improve the efficiency of repair work by allowing the loading of block bricks arranged in the upper layer as well as the lower layer of the brick when repairing the brick in the combustion chamber An object is to provide a transport device.

本発明者は、炉外で成形したブロック積み煉瓦をコークス炉内に搬入する際に、吊り装置が炉内ビーム等と干渉するのを防ぐ技術について検討した。そして、炭化室の天井に炉内ビームを固定し、その炉内ビームに沿って移動する走行装置から吊り装置を吊り下げてブロック積み煉瓦を挟持することによって、補修すべき煉瓦の下層部のみならず上層部に配置されるブロック積み煉瓦を炉内に搬入できるという知見を得た。   The present inventor has examined a technique for preventing the suspension device from interfering with the beam in the furnace when the block brick formed outside the furnace is carried into the coke oven. Then, by fixing the in-furnace beam on the ceiling of the carbonization chamber, and hanging the suspension device from the traveling device moving along the in-furnace beam and sandwiching the block pile brick, only the lower part of the brick to be repaired The knowledge that block bricks placed in the upper layer can be carried into the furnace.

本発明は、このような知見に基づいてなされたものである。
すなわち本発明は、コークス炉の燃焼室を内蔵する煉瓦を補修するために炉外で成形したブロック積み煉瓦をコークス炉内に搬入する煉瓦運搬装置であって、煉瓦の両側に位置する炭化室の天井にそれぞれ固定される合計２本の炉内ビームと、炉内ビームに沿って移動可能にそれぞれ装着される合計２台の走行装置と、走行装置から吊り下げられてブロック積み煉瓦を挟持する１個の吊り装置と、を有するコークス炉の燃焼室煉瓦補修用の煉瓦運搬装置である。 The present invention has been made based on such knowledge.
That is, the present invention is a brick transporting apparatus for carrying block bricks molded outside a furnace to repair bricks containing a combustion chamber of a coke oven into a coke oven. A total of two in-furnace beams fixed to the ceiling, a total of two traveling devices each mounted so as to be movable along the in-furnace beam, and a block brick that is suspended from the traveling device 1 A brick conveying device for repairing a combustion chamber brick in a coke oven having a suspension device.

本発明の煉瓦運搬装置においては、炭化室の天井に設けられた装炭口に設置される固定金具で炉内ビームを固定することが好ましい。さらに、炭化室内の炉内ビームの最奥端に支持柱を取り付け、支持柱の下端を炭化室の床面に固定することが好ましい。また、吊り装置が、ブロック積み煉瓦の側面に沿って押圧部材を有し、押圧部材の内側にゴムを配設して、押圧部材をボルトでブロック積み煉瓦に押圧することが好ましい。   In the brick conveying apparatus of the present invention, it is preferable to fix the in-furnace beam with a fixing metal fitting installed in a charcoal opening provided on the ceiling of the carbonization chamber. Furthermore, it is preferable to attach a support column to the innermost end of the in-furnace beam in the carbonization chamber and fix the lower end of the support column to the floor surface of the carbonization chamber. Moreover, it is preferable that a suspension device has a pressing member along the side surface of a block building brick, arrange | positions rubber | gum inside a pressing member, and presses a pressing member to a block building brick with a volt | bolt.

本発明に係る煉瓦運搬装置は、燃焼室の煉瓦を補修するにあたって、煉瓦の下層部のみならず上層部に配置されるブロック積み煉瓦を搬入する際に使用でき、補修作業の効率向上を図ることが可能となり、産業上格段の効果を奏する。   The brick transport device according to the present invention can be used when carrying in bricks placed in the upper layer as well as the lower layer of the brick when repairing the brick in the combustion chamber, and to improve the efficiency of repair work. Can be achieved, and it has a remarkable industrial effect.

本発明の煉瓦運搬装置でブロック積み煉瓦を炉内に搬入する例を模式的に示す垂直断面図である。It is a vertical sectional view which shows typically the example which carries a block pile brick into a furnace with the brick conveyance device of the present invention. 図１のＡ−Ａ矢視断面の例を示す断面図である。It is sectional drawing which shows the example of the AA arrow cross section of FIG. 図１のＡ−Ａ矢視断面の他の例を示す断面図である。It is sectional drawing which shows the other example of an AA arrow cross section of FIG. 従来の煉瓦運搬装置でブロック積み煉瓦を炉内に搬入する例を模式的に示す垂直断面図である。It is a vertical sectional view which shows typically the example which carries a block pile brick in a furnace with the conventional brick conveyance device. コークス炉の要部を模式的に示す水平断面図である。It is a horizontal sectional view which shows typically the principal part of a coke oven. 図５の煉瓦の例を模式的に示す斜視図である。It is a perspective view which shows the example of the brick of FIG. 5 typically.

図１は、本発明の煉瓦運搬装置を用いてブロック積み煉瓦を炉内に搬入する例を模式的に示す垂直断面図である。補修すべき煉瓦3aの両側に位置する炭化室の天井に、それぞれ炉内ビーム６（合計２本）を固定し、その炉内ビーム６に沿って移動可能な走行装置７を各炉内ビーム６に１台ずつ（合計２台）装着する。そして、走行装置７から吊り装置８を吊り下げて、炉外で成形したブロック積み煉瓦９を挟持し、走行装置７を走行させてコークス炉内に搬入する。   FIG. 1 is a vertical sectional view schematically showing an example in which block bricks are carried into a furnace using the brick transport device of the present invention. In-furnace beams 6 (two in total) are fixed to the ceilings of the carbonization chambers located on both sides of the brick 3a to be repaired, and traveling devices 7 that can move along the in-furnace beams 6 are connected to the in-furnace beams 6. Install one unit at a time (2 units in total). Then, the suspension device 8 is suspended from the traveling device 7, the block brick 9 formed outside the furnace is sandwiched, and the traveling device 7 is caused to travel and carried into the coke oven.

図１に示すように、本発明の煉瓦運搬装置を用いる場合も、補修すべき煉瓦3aを解体した後で崩落するのを防止するために、覗き孔４に天井吊り金物５を設置して、その煉瓦3aの上部を保持する。ただし天井吊り金物５に炉内ビーム６を固定する必要はないので、図４に示すような従来の煉瓦運搬装置に比べて、高い位置まで吊り装置８を上昇させることができる。   As shown in FIG. 1, when using the brick transport device of the present invention, in order to prevent the brick 3a to be repaired from collapsing, a ceiling hanging hardware 5 is installed in the peephole 4; The upper part of the brick 3a is held. However, since it is not necessary to fix the in-furnace beam 6 to the ceiling hanger 5, the suspension device 8 can be raised to a higher position than the conventional brick conveying device as shown in FIG. 4.

図２は、図１のＡ−Ａ矢視の断面図である。なお、図１では炉外ビーム11およびそれに付随するウインチ13、ワイヤ14は図示を省略する。
図２に示すように、吊り装置８はブロック積み煉瓦９の側面に沿って押圧部材18を有し、押圧部材18の内側にゴム19を配設して、そのゴム19をボルト17でブロック積み煉瓦９に押圧することが好ましい。ゴム19の摩擦力で、ブロック積み煉瓦９の滑落を防止しながら、ブロック積み煉瓦９の側面を挟持して吊り上げることが可能となり、吊り装置８の全高を減少することができる。 2 is a cross-sectional view taken along the line AA in FIG. In FIG. 1, the out-of-furnace beam 11, the winch 13 and the wire 14 associated therewith are not shown.
As shown in FIG. 2, the suspension device 8 has a pressing member 18 along the side surface of the block brick 9, a rubber 19 is disposed inside the pressing member 18, and the rubber 19 is block-stacked with bolts 17. It is preferable to press against the brick 9. The frictional force of the rubber 19 makes it possible to lift the block brick 9 while sandwiching the side surface of the block brick 9 while preventing the block brick 9 from slipping down, thereby reducing the overall height of the suspension device 8.

また、図２に示すように、炭化室内の炉内ビーム６の最奥部に支持柱10を取り付け、その支持柱10の下端を炭化室の床面に固定することによって、炉内ビーム６を炭化室の天井に固定することが好ましい。その理由は、炭化室の天井に石炭を装入するための開口部12（以下、装炭口という）が設けられているが、燃焼室に設けられる覗き孔４よりも数が少ないからである。つまり、炉内ビーム６と装炭口12が図２に示すように配置される場合、炉内ビーム６の長手方向に装炭口12が１ケ所しかないので、その装炭口12に固定金具（図示せず）を設置するだけでは、炉内ビーム６を固定しかつ安定せることが困難である。   In addition, as shown in FIG. 2, a support column 10 is attached to the innermost part of the in-furnace beam 6 in the carbonization chamber, and the lower end of the support column 10 is fixed to the floor surface of the carbonization chamber. It is preferable to fix to the ceiling of the carbonization chamber. The reason is that an opening 12 (hereinafter referred to as a coal opening) for charging coal is provided on the ceiling of the carbonization chamber, but the number is smaller than that of the peep holes 4 provided in the combustion chamber. . That is, when the in-furnace beam 6 and the coal charging port 12 are arranged as shown in FIG. 2, there is only one coal charging port 12 in the longitudinal direction of the in-furnace beam 6. It is difficult to fix and stabilize the in-furnace beam 6 only by installing (not shown).

ただし、炉内ビーム６の長手方向に複数の装炭口12が配置される場合は、それぞれの装炭口12に固定金具を設置して炉内ビーム６を固定しかつ安定せることができるので、支持柱10を必ずしも取り付ける必要はない。あるいは、支持柱10と装炭口12の固定金具とを併用しても良い。
また図２には、炉内ビーム６に連結して炉外に延長するための炉外ビーム11を示す。図２に示す炉外ビーム11は、折り畳み式であり、炭化室の開口部の上面に設けたウインチ13でワイヤ14を送り出すことによって炉外ビーム11を図２に示す作業姿勢に保つことができる。一方、ウインチ13でワイヤ14を巻き上げれば、炉外ビーム11を直立させて待機姿勢に保つことができる。 However, in the case where a plurality of coal charging ports 12 are arranged in the longitudinal direction of the in-furnace beam 6, it is possible to fix and stabilize the in-furnace beam 6 by installing a fixing fitting in each of the charging ports 12. It is not always necessary to attach the support column 10. Alternatively, the support pillar 10 and the fixing bracket of the coal opening 12 may be used in combination.
FIG. 2 shows an out-of-furnace beam 11 connected to the in-furnace beam 6 and extending outside the furnace. The out-of-furnace beam 11 shown in FIG. 2 is a foldable type, and the out-of-furnace beam 11 can be maintained in the working posture shown in FIG. 2 by sending out the wire 14 with a winch 13 provided on the upper surface of the opening of the carbonization chamber. . On the other hand, if the wire 14 is wound up by the winch 13, the out-of-furnace beam 11 can be kept upright and kept in a standby posture.

コークス炉の燃焼室の煉瓦を補修する場合、本発明の煉瓦運搬装置を設置するために補修すべき燃焼室の両側の炭化室の稼働を停止するが、その他の炭化室の操業は継続するので、押出機やガイド車が随時走行する状態で該当する燃焼室の煉瓦の補修を行なう。そのため押出機やガイド車が通過するときは、炉外ビーム11を直立させて待機姿勢に保つ必要がある。   When repairing bricks in the combustion chamber of the coke oven, the operation of the carbonization chambers on both sides of the combustion chamber to be repaired to install the brick transport device of the present invention is stopped, but the operation of other carbonization chambers continues. The bricks in the corresponding combustion chamber are repaired while the extruder and the guide vehicle are traveling as needed. For this reason, when the extruder or the guide wheel passes, it is necessary to keep the out-of-furnace beam 11 upright and in a standby posture.

そして押出機やガイド車が通過した後、図２に示すように炉外ビーム11を図２に示す作業姿勢に保って、ブロック積み煉瓦９を炉内に搬入する。その際、ブロック積み煉瓦９を補修すべき煉瓦の位置まで台車15で運搬し、吊り装置８で挟持して吊り上げ、さらに走行装置７を炉外ビーム11から炉内ビーム６へ走行させて、ブロック積み煉瓦９を炉内に搬入する。   Then, after the extruder and the guide wheel have passed, the block bricks 9 are carried into the furnace while keeping the outside beam 11 in the working posture shown in FIG. 2 as shown in FIG. At that time, the block brick 9 is transported by the carriage 15 to the position of the brick to be repaired, sandwiched and lifted by the suspension device 8, and the traveling device 7 is caused to travel from the out-of-furnace beam 11 to the in-furnace beam 6. The brick 9 is carried into the furnace.

図３は、炉外ビーム11の他の例を示す断面図である。図３に示す例は、台車移動式であり、台車15上に組立てた固定脚16に炉外ビーム11を固定し、ブロック積み煉瓦９を載置した台車15を補修すべき煉瓦の位置まで移動することによって、炉外ビーム11を炉内ビーム６に連結し、さらに、ブロック積み煉瓦９を吊り装置８で挟持して吊り上げ、走行装置７を炉外ビーム11から炉内ビーム６へ走行させて、ブロック積み煉瓦９を炉内に搬入する。固定脚16の骨組みは、吊り装置８の移動や走行装置７の走行と干渉しないように組立てる。また、押出機やガイド車が走行するときは、台車15を退避させる。   FIG. 3 is a cross-sectional view showing another example of the out-of-furnace beam 11. The example shown in FIG. 3 is a cart moving type, and the outside beam 11 is fixed to a fixed leg 16 assembled on the cart 15, and the cart 15 on which the block brick 9 is placed is moved to the position of the brick to be repaired. In this way, the out-of-furnace beam 11 is connected to the in-furnace beam 6, the block brick 9 is sandwiched and lifted by the suspension device 8, and the traveling device 7 travels from the out-of-furnace beam 11 to the in-furnace beam 6. Then, the block brick 9 is carried into the furnace. The frame of the fixed leg 16 is assembled so as not to interfere with the movement of the suspension device 8 and the traveling of the traveling device 7. Further, when the extruder or the guide vehicle travels, the carriage 15 is retracted.

このようにして炭化室の天井に固定した炉内ビーム６と、折り畳み式や台車移動式の炉外ビーム11とを連結して、ブロック積み煉瓦９を炉内に搬入すれば、燃焼室の崩落を防止するための天井吊り金物５に炉内ビーム６を固定する必要はないので、炉内ビーム６と吊り装置８の干渉がなくなる。その結果、高い位置まで吊り装置８を上昇させることができ、ひいては煉瓦３の上層部までブロック積み煉瓦９を搬入して補修することが可能となり、補修作業を短時間で効率良く行なうことができる。   If the in-furnace beam 6 fixed to the ceiling of the carbonization chamber in this way is connected to the folding or trolley-movable out-of-furnace beam 11 and the block brick 9 is carried into the furnace, the combustion chamber collapses. Since there is no need to fix the in-furnace beam 6 to the ceiling hanger 5 for preventing the interference, the interference between the in-furnace beam 6 and the suspension device 8 is eliminated. As a result, it is possible to raise the suspension device 8 to a high position, so that it is possible to carry in and repair the block pile brick 9 to the upper layer part of the brick 3, and the repair work can be performed efficiently in a short time. .

全45段の煉瓦で構成される燃焼室の煉瓦３を下から42段まで補修する工事を行なった。その手順を以下に説明する。
図１に示すように、燃焼室の煉瓦３を下から42段まで解体した後、炉外で成形したブロック積み煉瓦９を本発明の煉瓦運搬装置を用いて、炉内に搬入した。吊り装置８は、押圧部材18の内側にゴム19を配設して、そのゴム19を押し付けてブロック積み煉瓦９を挟持する型式のものを使用した。煉瓦３の最上層３段（＝45段−42段）の煉瓦は、崩落を防止するために、天井吊り金物５で固定した。炉外ビーム11は、図２に示すような折り畳み式を採用した。これを発明例とする。 We repaired the brick 3 in the combustion chamber, which consists of 45 steps of bricks, from the bottom up to 42 steps. The procedure will be described below.
As shown in FIG. 1, after the bricks 3 in the combustion chamber were disassembled from the bottom to the 42th stage, the block bricks 9 formed outside the furnace were carried into the furnace using the brick transport device of the present invention. The suspension device 8 is of a type in which a rubber 19 is disposed inside the pressing member 18 and the rubber 19 is pressed to sandwich the block brick 9. The bricks of the top three layers (= 45 to 42) of the brick 3 were fixed with the ceiling hanging hardware 5 in order to prevent collapse. The out-of-furnace beam 11 employs a folding type as shown in FIG. This is an invention example.

一方で従来は、同じコークス炉の煉瓦３の補修の際に、図４に示すように、天井吊り金物５の直下に配置した炉内ビーム６を用いて、ブロック積み煉瓦９を炉内に搬入していた。吊り装置８は、上部にジャッキボルト20を配設して、ブロック積み煉瓦９を挟持する型式のものを使用していた。これを従来例とする。
発明例では、炉内ビームと吊り装置は干渉せず、高い位置まで吊り装置を上昇させることができるので、炉内でブロック積み煉瓦を積み上げて、下から39段まで補修することができた。上層部の残り３段（＝42段−39段）は人力で煉瓦を積み上げて補修した。 On the other hand, conventionally, when the brick 3 of the same coke oven is repaired, the block brick 9 is carried into the furnace by using the in-furnace beam 6 arranged immediately below the ceiling hanging hardware 5 as shown in FIG. Was. The suspension device 8 is of a type in which jack bolts 20 are disposed at the upper portion and the block brick 9 is sandwiched. This is a conventional example.
In the invention example, the beam in the furnace and the suspension device do not interfere with each other, and the suspension device can be raised to a high position. Therefore, the block bricks can be stacked in the furnace and repaired from the bottom to the 39th stage. The remaining three tiers (= 42-39 tiers) in the upper layer were repaired by manually building up bricks.

従来例は、炉内ビームと吊り装置が干渉し、しかも吊り装置の上部に配設したジャッキボルトによって吊り装置の全高が大きくなるので、下から30段まで補修した後、上層部の残り12段（＝42段−30段）を人力で補修していた。
したがって発明例では、人力で煉瓦を積み上げる補修作業を大幅に削減し、従来例の１／４（＝３／12）とすることができた。 In the conventional example, the beam in the furnace interferes with the suspension device, and the overall height of the suspension device is increased by the jack bolts arranged on the upper portion of the suspension device. (= 42 -30 steps) was repaired manually.
Therefore, in the example of an invention, the repair work which piles up bricks manually was reduced significantly, and it was able to be set to 1/4 (= 3/12) of a conventional example.
