【発明の詳細な説明】
本発明は、建築工事が下層から上層に順次移っていく過
程に合わせて、機械室を順次上方に移動させていく移動
機械室形エレベータにおいて、機械室の上方への移動時
すなわちエレベータ昇降路行程延長時の工法に関するも
ので、更に詳細には巻上ロープの繰り出し方法に関する
。[Detailed Description of the Invention] The present invention provides a mobile machine room type elevator that sequentially moves the machine room upward in accordance with the process in which construction work is sequentially transferred from the lower floor to the upper floor. The present invention relates to a construction method during movement, that is, when extending the journey of an elevator hoistway, and more specifically relates to a method for paying out a hoisting rope.
近年、高層ビル建築技術の発達は目ざましく、これに伴
って建築工事の効率向上のため建築工事の進行過程に合
わせ、昇降路に段階的に機械室を仮設し、この仮設機械
室にてかごを運転し、昇降路等の工事を行なう工事用エ
レベータが多く用いられている。In recent years, the development of high-rise building construction technology has been remarkable, and in order to improve the efficiency of construction work, temporary machine rooms have been built in stages in the hoistway as the construction work progresses, and cars are operated in these temporary machine rooms. Construction elevators are often used to operate hoistway construction work.
この場合仮設機械室の上方への移動の都度、前工程に要
した巻上ロープ（以下、単にロープという）を廃棄し、
新たに必要昇降行程分のロープをセットしていたのでは
、作業能率が低下するばかりでなくロープが無駄になる
ため、予め最終行程に必要な長さのロープを巻取ってお
く巻取り装置と、ロープ繰り出し装置とを備え、機械室
の上方への移動と共に順次ロープを繰り出す方法が一般
にとられている。In this case, each time the temporary machine room is moved upwards, the hoisting rope (hereinafter simply referred to as rope) required for the previous process is discarded.
If a new rope is set for the required lifting stroke, the work efficiency will not only decrease, but the rope will also be wasted. , a rope payout device, and a method is generally adopted in which the ropes are sequentially paid out as the machine moves upward from the machine room.
第１図及び第２図により一般的な工事用エレベータの構
成と機械室移動時のロープ繰り出し方法を説明する。The configuration of a general construction elevator and the method of letting out a rope when moving to a machine room will be explained with reference to FIGS. 1 and 2.
建築物受梁１上に支持された仮設の機械室２にはロープ
繰り出し装置３、ロープ巻取り装置４、巻上装置５及び
そらせ車６が、また上部には吊り上げフック７が設けら
れている。A temporary machine room 2 supported on a building support beam 1 is equipped with a rope payout device 3, a rope winding device 4, a hoisting device 5, and a deflection wheel 6, and a lifting hook 7 is provided at the top. .
ここでロープ繰り出し装置３はエレベータのサービス運
転時にはロープ８を保持してロープ８の繰り出しを阻止
し、機械室２の上方への移動時には保持力を緩めてロー
プ８を繰り出し得る構造となって、いる。Here, the rope payout device 3 has a structure that holds the rope 8 and prevents the rope 8 from being paid out during the service operation of the elevator, and allows the rope 8 to be paid out by loosening the holding force when moving upwards in the machine room 2. There is.
ロープ８はロープ巻取り装置４より、ロープ繰り出し装
置３を経て釣り合い錘１１のシーブ１２、そらせ車６、
巻上装置５、かご９、のシーブ１０へと掛は渡され、他
端が機械室２に到っている。The rope 8 is passed through the rope winding device 4, the rope feeding device 3, the sheave 12 of the counterweight 11, the deflection wheel 6,
The hook is passed to the sheave 10 of the hoisting device 5, the car 9, and the other end reaches the machine room 2.
１３はバッファである。以上の構成において建築工事が
進行し、機械室２を距離Ａだけ上昇させる場合には、第
１図に示すようにまずかと９を機械室２の下部にチェー
ンブロック１４等で吊り下げ、一方釣り合い錘１１はピ
ット下部まで下げて固定する。13 is a buffer. When the construction work progresses with the above configuration and the machine room 2 is to be raised by a distance A, as shown in FIG. The weight 11 is lowered to the bottom of the pit and fixed.
次にロープ繰り出し装置３を調整してロープ８の保持力
を緩め、且つロープ巻取り装置４を回転可能とする。Next, the rope payout device 3 is adjusted to loosen the holding force on the rope 8, and the rope winding device 4 is made rotatable.
しかる後、機械室２並びにこれに吊り下げられたかと９
をタワークレーン１５等によりフック７を介して吊り上
げる。After that, machine room 2 and the 9 hanging there
is lifted up via the hook 7 by a tower crane 15 or the like.
この場合ロープ繰り出し装置３によるロープ８の保持力
をロープ８が自重で落下しない程度の値に保つと、タワ
ークレーン１５に過大な負荷を与えることなくロープ８
はロープ巻取り装置４より機械室２の移動に応じて自動
的に繰り出されることになる。In this case, if the holding force of the rope 8 by the rope feeding device 3 is maintained at a value that prevents the rope 8 from falling due to its own weight, the rope 8 can be
is automatically unwound by the rope winding device 4 in accordance with the movement of the machine room 2.
機械室２の移動後は第２図に示すように受梁１６により
機械室２を建物に固定し、次にロープ繰り出し装置３を
復旧してロープ８を保持し、チェーンブロック１４を徐
々に緩めて取り除き機械室の移動作業を完了する。After moving the machine room 2, as shown in Fig. 2, fix the machine room 2 to the building with support beams 16, then restore the rope feeder 3 to hold the rope 8, and gradually loosen the chain block 14. to complete the movement of the machine room.
ところで上記のような方法によると、機械室２の移動と
ロープ８の繰り出しが同時に行なわれることになるが、
一般に建設用タワークレーン１５の巻上速度は早く、ま
たタワークレーン１５の操作者はロープ８の繰り出し状
況を直接確認することが困難であるため、例えばロープ
繰り出し装置３に何らかの異常が生じて、ロープ８が拘
速されたり或いはロープ８が必要以上に繰り出されて他
の機器に巻付く恐れも考えられ、非常に大きな危険と困
難とを伴うものであった。By the way, according to the method described above, the movement of the machine room 2 and the feeding out of the rope 8 are performed at the same time.
In general, the hoisting speed of the construction tower crane 15 is fast, and it is difficult for the operator of the tower crane 15 to directly check the situation of the rope 8 being paid out. There is a possibility that the rope 8 may be restrained or the rope 8 may be unrolled out more than necessary and become wrapped around other equipment, which is accompanied by great danger and difficulty.
本発明はこうした点に注目しなされたもので、機械室２
の移動作業とロープの繰り出し作業とを別々に行なうこ
とができ、従って機械室２内でロープ８の繰り出し状況
を確認しながら操作できる、安全でしかも効率のよいロ
ープ繰り出し方法を提供するものである。The present invention was made with attention to these points, and the machine room 2
To provide a safe and efficient rope letting-out method in which the moving work of the rope 8 and the rope letting-out work can be carried out separately, and therefore the operation can be performed while checking the paying-out status of the rope 8 in the machine room 2. .
以下本発明による機械室移動作業の手順を第３図乃至第
６図により説明する。The procedure for moving the machine room according to the present invention will be explained below with reference to FIGS. 3 to 6.
まず第３図に示す如く、かご９をチェーンブロック１４
等により機械室２の下部に吊り下げた状態で、タワーク
レーン１５により吊り上げフック７を介して機械室２を
かと９、釣り合い錘１１と共に一体で吊り上げる。First, as shown in Figure 3, the car 9 is moved to the chain block 14.
etc., and the machine room 2 is lifted together with the heel 9 and the counterweight 11 by a tower crane 15 via the lifting hook 7.
この時ロープ繰り出し装置３はロープ８を保持し、ロー
プ８を繰り出し得ない状態となっている。At this time, the rope payout device 3 holds the rope 8 and is in a state in which it cannot pay out the rope 8.
機械室２を所定の位置まで吊り上げ後は第４図に示す如
く、受梁１６により機械室２を建築物に固定する。After lifting the machine room 2 to a predetermined position, the machine room 2 is fixed to the building using support beams 16, as shown in FIG.
次に第５図に示す如く、タワークレーン１５を機械室２
より切り離して釣り合い錘１１を吊り下げる。Next, as shown in FIG. 5, the tower crane 15 is moved to the machine room 2.
Separate it further and hang the counterweight 11.
その後ロープ繰り出し装置３を調整してロープ８の保持
力を緩め、タワークレーン１５の操作により釣り合い錘
１１を徐々に下げていくとロープ８がロープ巻取り装置
４より繰り出されることになる。Thereafter, the rope payout device 3 is adjusted to loosen the holding force on the rope 8, and the counterweight 11 is gradually lowered by operating the tower crane 15, so that the rope 8 is paid out from the rope winding device 4.
釣り合い錘１１を所定の位置まで吊り下げた後、ロープ
繰り出し装置３を復旧してロープ８を保持し、ロープ８
が繰り出し得ない状態であることを確認して釣り合い錘
１１よりタワークレーン１５を切り離し、次にチェーン

業を完了する。After suspending the counterweight 11 to a predetermined position, the rope feeding device 3 is restored and the rope 8 is held.
After confirming that the tower crane 15 is in a state where it cannot be extended, the tower crane 15 is separated from the counterweight 11, and then the chain block 14 is gradually removed, and the work of moving the machine room 2 is completed.
以上のように本発明によれば機械室２の移動とロープ８
の繰り出し作業とを別々に行なうことができ、しかもロ
ープ８の繰り出しはタワークレーン１５等の操作により
釣り合い錘１１の自重を利用して行なうため、前述のよ
うな危険を伴うことなく安全なロープ繰り出し作業を提
供することができる。As described above, according to the present invention, the movement of the machine room 2 and the rope 8
Moreover, since the rope 8 is fed out using the weight of the counterweight 11 by operating the tower crane 15, etc., the rope 8 can be fed out safely without the dangers described above. can provide work.
なお、上記の実施例において、かご９と釣り合い錘１１
とを入れ替えても同様の手順方法で実施が可能である。In addition, in the above embodiment, the cage 9 and the counterweight 11
It is possible to perform the same procedure even if the two are replaced.
