Description

この発明は、巻上機が昇降路内の下部に設置されている既設の機械室レスエレベータを、巻上機が昇降路内の上部に設置されている機械室レスエレベータに改修するエレベータの改修方法に関するものである。   The present invention is a modification of an elevator in which an existing machine room-less elevator in which a hoisting machine is installed in the lower part of the hoistway is replaced with a machine room-less elevator in which the hoisting machine is installed in the upper part of the hoistway. It is about the method.

従来のエレベータの改修方法では、既設のかごの上部にかご吊り車を取り付けるとともに、既設の釣合おもりの上部に釣合おもり吊り車を取り付ける。また、機械室に設置された機械台から巻上機を撤去する。そして、新たな巻上機及びエンドブラケットを機械台に設置する。この後、巻上機、かご吊り車及び釣合おもり吊り車に主索を巻き掛け、主索の両端をエンドブラケットに接続する（例えば、特許文献１参照）。   In the conventional elevator repair method, a car suspension car is attached to the upper part of an existing car, and a counterweight suspension car is attached to the upper part of an existing counterweight. Also, the hoisting machine is removed from the machine base installed in the machine room. Then, a new hoisting machine and an end bracket are installed on the machine base. Thereafter, the main rope is wound around the hoisting machine, the car suspension car, and the counterweight suspension car, and both ends of the main rope are connected to the end bracket (for example, see Patent Document 1).

The counterweight-side suspension connecting portion 25 after the repair is horizontally installed on the first and second return wheels 17a and 17b. Other configurations are the same as those before the repair, but may be replaced with new devices as necessary.

このような機械室レスエレベータの改修方法では、真上から見て、既設のかご側懸架体接続部１６ａと既設の釣合おもり側懸架体接続部１６ｂとの間の領域を改修後の懸架体２６が通るように、上部支持体１３に新たな巻上機２１を設置するので、多くの機器を流用しつつ、取付寸法及び外形寸法が改修前とは異なる巻上機２１を設置することができる。これにより、最新の巻上機２１を使用しつつ、改修工期の短縮を図ることができる。   In such a repair method of the machine room-less elevator, as viewed from directly above, the suspended body after repairing the region between the existing car-side suspension connection part 16a and the existing counterweight-side suspension connection part 16b. Since a new hoisting machine 21 is installed on the upper support 13 so that 26 passes, it is possible to install the hoisting machine 21 whose mounting dimensions and external dimensions are different from those before the repair while diverting many devices. it can. As a result, the repair work period can be shortened while using the latest hoisting machine 21.

また、巻上機２１を昇降路４内の上部に配置することができるため、万一ピットが冠水しても、巻上機２１が濡れることがない。   Moreover, since the hoisting machine 21 can be arrange | positioned at the upper part in the hoistway 4, even if a pit is flooded, the hoisting machine 21 does not get wet.

さらに、レイアウトの変更が少ない上、改修前よりも懸架体２６の経路が簡単になるため、懸架体２６へのダメージを減少させることができる。   Furthermore, since the layout is less changed and the path of the suspension body 26 becomes simpler than before the repair, damage to the suspension body 26 can be reduced.

さらにまた、新たな巻上機２１として薄型巻上機を用いたので、昇降路４内の上部の限られたスペースに巻上機２１を容易に設置することができる。   Furthermore, since the thin hoisting machine is used as the new hoisting machine 21, the hoisting machine 21 can be easily installed in a limited space in the upper part of the hoistway 4.

実施の形態２．
次に、図９はこの発明の実施の形態２による改修後の機械室レスエレベータを示す概略の平面図である。実施の形態２では、新たな巻上機２１の駆動シーブ２３からの改修後の懸架体２６の落とし位置の一方が、既設のかご側懸架体接続部１６ａへの既設の懸架体３の立ち上がり位置と同じ位置又はその近傍となっている。また、新たな巻上機２１の駆動シーブ２３からの改修後の懸架体２６の落とし位置の他方が、既設の釣合おもり側懸架体接続部１６ｂへの既設の懸架体３の立ち上がり位置と同じ位置又はその近傍となっている。このようなレイアウトを実現するため、駆動シーブ２３の径が実施の形態１よりも大きい。他の構成及び改修方法は、実施の形態１と同様である。 Embodiment 2. FIG.
Next, FIG. 9 is a schematic plan view showing a machine room-less elevator after repair according to Embodiment 2 of the present invention. In the second embodiment, one of the drop positions of the suspension 26 after the repair from the drive sheave 23 of the new hoisting machine 21 is the rising position of the existing suspension 3 to the existing car-side suspension connection portion 16a. It is the same position or its vicinity. Further, the other of the drop positions of the suspension 26 after the repair from the drive sheave 23 of the new hoisting machine 21 is the same as the rising position of the existing suspension 3 to the existing counterweight-side suspension connection portion 16b. The position or its vicinity. In order to realize such a layout, the diameter of the drive sheave 23 is larger than that of the first embodiment. Other configurations and repair methods are the same as those in the first embodiment.

このように、新たな巻上機２１の駆動シーブ２３からの懸架体２６の落とし位置を、既設の懸架体接続部１６ａ，１６ｂへの既設の懸架体３の立ち上がり位置に合わせることにより、懸架体２６の倒れ量が改修前とほぼ同じとなり、レイアウトへの影響を少なくすることができる。   As described above, the suspension body 26 is dropped from the drive sheave 23 of the new hoisting machine 21 by matching the position where the suspension body 26 is raised to the existing suspension body connection portions 16a and 16b. The amount of fall of 26 is almost the same as that before the repair, and the influence on the layout can be reduced.

なお、改修後のかご側懸架体接続部２４を昇降路４内の下部に設置し、改修後の懸架体２６を既設のかご返し車１４にも巻き掛ける構成としてもよい。   The car-side suspension connecting part 24 after the repair may be installed in the lower part of the hoistway 4 and the suspended body 26 after the repair may be wound around the existing car return wheel 14.

また、改修後のかご側懸架体接続部２４を、上部支持体１３の既設の釣合おもり返し車１５の設置位置又はその近傍に設置し、改修後の懸架体２６をかご返し車１４及び既設の巻上機５の駆動シーブ７にも巻き掛ける構成としてもよい。この場合、改修後のエレベータでは、既設の巻上機５は駆動力を発生せず、駆動シーブ７は下部返し車として使用される。このとき、既設の巻上機５のコイル部分を取り外して抵抗を無くすことにより、駆動シーブ７を下部返し車として使用しても余計な負荷がかかることがない。   Further, the car-side suspension connection part 24 after the repair is installed at or near the installation position of the existing counterweight return wheel 15 of the upper support 13, and the suspension 26 after the repair is installed in the car return car 14 and the existing installation. It is good also as a structure wound around the drive sheave 7 of the hoisting machine 5. In this case, in the upgraded elevator, the existing hoisting machine 5 does not generate a driving force, and the driving sheave 7 is used as a lower return wheel. At this time, by removing the coil portion of the existing hoisting machine 5 and eliminating the resistance, no extra load is applied even if the drive sheave 7 is used as a lower return wheel.

さらに、上記の例では、既設の懸架体３、既設の巻上機５、かご返し車１４及び釣合おもり返し車１５、及び既設の懸架体接続部１６ａ，１６ｂを撤去したが、改修後のエレベータの邪魔にならなければ、これらの機器を撤去せず、そのまま残してもよい。これにより、廃棄物を削減することができる。   Further, in the above example, the existing suspension body 3, the existing hoisting machine 5, the car return wheel 14 and the counterweight return wheel 15, and the existing suspension body connection portions 16a and 16b have been removed. If the equipment does not get in the way of the elevator, these devices may be left as they are without being removed. Thereby, waste can be reduced.

さらにまた、改修後の懸架体２６としては、新たな懸架体を用いるのが好ましいが、既設の懸架体３の長さを短くして改修後の懸架体２６として流用することも可能である。
また、改修後の懸架体接続部２４，２５としては、新たな懸架体接続部を用いるのが好ましいが、既設の懸架体接続部１６ａ，１６ｂを改修後の懸架体接続部として流用することも可能である。 Furthermore, although it is preferable to use a new suspension body as the modified suspension body 26, the length of the existing suspension body 3 can be shortened and used as the modified suspension body 26.
Moreover, it is preferable to use a new suspension connection part as the suspension connection parts 24 and 25 after the modification, but the existing suspension connection parts 16a and 16b may be used as the suspension connection parts after the modification. Is possible.

さらに、上記の例では、駆動シーブ２３がかご１側を向くように巻上機２１が設置されているが、駆動シーブ２３がご１とは反対側を向くように、即ち、巻上機本体２２がかご１側を向くように巻上機２１を設置してもよい。この場合、かご１上から巻上機本体２２の保守点検を容易に行うことができる。   Further, in the above example, the hoisting machine 21 is installed so that the driving sheave 23 faces the car 1 side, but the driving sheave 23 faces the opposite side from the car 1, that is, the hoisting machine main body. The hoisting machine 21 may be installed so that 22 faces the car 1 side. In this case, maintenance and inspection of the hoisting machine main body 22 can be easily performed from the car 1.
