本発明は大型吊下式ボイラの組立据付方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for assembling and installing a large hanging boiler.
従来、大型吊下式ボイラの組立据付は第１図および第２
図に示すような方法を採っていた。Conventionally, the assembly and installation of large hanging boilers was performed using the methods shown in Figures 1 and 2.
The method shown in the figure was adopted.
すなわち、まずボイラ設置現地において鉄骨組立用のク

立てる。That is, first, a crane 1 for assembling the steel frame is installed vertically at the boiler installation site, and this crane 1 is used to assemble the steel frame members 2.
The steel frame 3 is assembled from the bottom upwards.
鉄骨フレーム３の組立が完了したのち、鉄骨フレームの
頂部に吊下げクレーン４を設置し、この吊下げクレーン
４によってボイラドラム５等のボイラ構成部材を順次重
下げて組立、据付を行う。After the assembly of the steel frame 3 is completed, a suspension crane 4 is installed on the top of the steel frame, and the boiler components such as the boiler drum 5 are sequentially lowered and assembled and installed using the suspension crane 4.
以上のような従来の組立、据付方法を採用すると、鉄骨

業を著しく軽減した大型吊下式ボイラの組立据付方法を
提供するものである。The present invention has been made to eliminate these drawbacks, and provides a method for assembling and installing a large hanging boiler that requires less man-hours at the installation site and significantly reduces work at heights. be.
以下、図面に示す実施例を使って本発明の詳細な説明す
る。Hereinafter, the present invention will be described in detail using embodiments shown in the drawings.
第３図〜第７図は本発明に係る組立据付方法を説明する
ためのもので、図において符号６で示すものは鉄骨フレ
ームを示し、この鉄骨フレーム６は工場内において組立
てられ、横倒状態で船舶やパージなどに積んでボイラ設
置現場へ搬送される。FIGS. 3 to 7 are for explaining the assembly and installation method according to the present invention. In the figures, the reference numeral 6 indicates a steel frame, and this steel frame 6 is assembled in a factory and placed in a horizontal position. It is then loaded onto a ship or purge vehicle and transported to the boiler installation site.
現地においては、第３図に示すように鉄骨フレーム６は
横倒状態にあり、その先端（垂設した状態では上端）が
予めボイラ設置際に垂設された補助基１０近くに位置す
るように配置される。At the site, as shown in Fig. 3, the steel frame 6 is lying on its side, and its tip (or upper end in the vertically installed state) is positioned near the auxiliary base 10 that was previously installed vertically when the boiler was installed. Placed.
このときすでに鉄骨フレーム６の一隅には移動車輪７が
取付けられ、鉄骨フレーム６の下側の中央部すなわち鉄
骨フレーム６の高さ方向の中間部および移動車輪Ｔと反
対側の隅部には滑車８，９が取付けられている。At this time, a moving wheel 7 is already attached to one corner of the steel frame 6, and a pulley is installed at the lower central part of the steel frame 6, that is, the middle part of the steel frame 6 in the height direction, and the corner opposite to the moving wheel T. 8 and 9 are installed.
一方、据付位置においては鉄骨フレーム６より高さの低
い補助基１０が垂設されており、その頂部には滑車１１
が配設されている。On the other hand, at the installation position, an auxiliary base 10 lower in height than the steel frame 6 is vertically installed, and a pulley 11 is mounted on the top of the auxiliary base 10.
is installed.
以上のような状態のもとに鉄骨フレーム６の滑車８，９
にワイヤ１２をかけ渡し、このワイヤ１２な補助基１０
の滑車１１に添接させて図示していないウィンチに接続
する。Under the above conditions, the pulleys 8 and 9 of the steel frame 6
The wire 12 is passed through the auxiliary group 10.
It is attached to a pulley 11 and connected to a winch (not shown).
また鉄骨フレーム６の補助基１０側の頂部の隅部には補
助ワイヤ１３の一端が固定されており、この補助ワイヤ
′１３の他端は前記滑車１１を介して同じくウィンチ方
向に導かれている。Further, one end of an auxiliary wire 13 is fixed to the top corner of the steel frame 6 on the side of the auxiliary base 10, and the other end of this auxiliary wire '13 is similarly guided in the winch direction via the pulley 11. .
この状態でまず、ワイヤ１３を引き込むと、鉄骨フレー
ム６は車輪７を転動させて補助基１０方向に引寄せられ
つつ第４図に示すように次第に引起こされ、さらにワイ
ヤ１２を引き込むことによって第５図に示すように補助
基１０に沿って直立される。In this state, when the wire 13 is first pulled in, the steel frame 6 is pulled toward the auxiliary base 10 by rolling the wheels 7, and is gradually raised as shown in FIG. It is erected along the auxiliary group 10 as shown in FIG.
この引起し作業中においては補助ワイヤ１３には常に一
定のテンションが与えられており、鉄骨フレーム６が転
倒しないように保持している。During this lifting operation, a constant tension is always applied to the auxiliary wire 13 to hold the steel frame 6 so that it does not fall.
鉄骨フレーム６の設置が終了したのちには第６図に示す
ように同じく工場内で組立完了なした完成ボイラ１４を
横倒状態で鉄骨フレーム６の近傍にまで搬送してくる。After the installation of the steel frame 6 is completed, as shown in FIG. 6, the completed boiler 14, which has also been assembled in the factory, is transported to the vicinity of the steel frame 6 in a horizontal position.
そして、鉄骨フレーム６の頂部に主吊上装置１５および
態量上装置１６を配設し、主吊上装置１５と完成ボイラ

量上装置１６と完成ボイラ１４の下側端に取付けられた
滑車１９との間に補助ワイヤ２０をかけ、完成ボイラ１
４の先端部を鉄骨フレーム６内に引き入れさらに吊上げ
て、第７図に示すように完成ボイラ１４を鉄骨フレーム
６の収容空間内に収容する。Then, a main lifting device 15 and a weight lifting device 16 are installed on the top of the steel frame 6, and a wire 18 is placed between the main lifting device 15 and a pulley 17 attached to the completed boiler. An auxiliary wire 20 is placed between the device 16 and a pulley 19 attached to the lower end of the completed boiler 14, and the completed boiler 1
4 is pulled into the steel frame 6 and further lifted, and the completed boiler 14 is housed in the housing space of the steel frame 6 as shown in FIG.
以上の説明から明らかなように、本発明の方法によれば
、鉄骨フレームおよびボイラの双方を必要な設備が整っ
た工場内で組立て、これを横倒状態で設置位置まで搬送
し、現地において引起こすという方法を採用しているた
め、作業環境の悪い現地での工事を大幅に簡略化でき、
また高所での作業が少ないため組立工事の危険作業も大
幅に減少する。As is clear from the above description, according to the method of the present invention, both the steel frame and the boiler are assembled in a factory equipped with the necessary equipment, transported on their side to the installation location, and then pulled on site. By adopting the method of raising the parts, construction work on-site with poor working environments can be greatly simplified.
Additionally, because there is less work to be done at heights, dangerous assembly work is also greatly reduced.
さらに現地にはボイラよりも低い補助基を立設するだけ
であるから経済的にも極めて有利となるなどの優れた効
果がある。Furthermore, since only an auxiliary unit that is lower than the boiler is erected on-site, it has excellent effects such as being extremely advantageous economically.
