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.

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).

特開２００１−２２００７８号公報Japanese Patent Laid-Open No. 2001-220078

上記のような機械室を持つタイプのエレベータの改修では、既設の機械台に新たな巻上機を設置するので、巻上機の取付寸法及び外形寸法の変更が比較的容易である。これに対して、従来の機械室レスエレベータでは、昇降路内の寸法上の制約が厳しいため、取付寸法及び外形寸法が改修前の巻上機と同一の巻上機を改修前と同じ位置に設置していた。また、取付寸法及び外形寸法が改修前とは異なる巻上機を設置する場合、昇降路内の全ての機器を撤去し新設する工法をとっており、改修工期がかなり長くなっていた。   In the repair of an elevator having a machine room as described above, since a new hoisting machine is installed on an existing machine base, it is relatively easy to change the mounting dimensions and the outer dimensions of the hoisting machine. On the other hand, in conventional machine room-less elevators, restrictions on the dimensions in the hoistway are severe, so the hoisting machine with the same mounting dimensions and outer dimensions as the hoisting machine before the refurbishment is placed in the same position as before It was installed. In addition, when installing a hoisting machine whose mounting dimensions and external dimensions are different from those before the repair, a construction method in which all the devices in the hoistway are removed and newly installed is taken, and the repair work period is considerably long.

この発明は、上記のような課題を解決するためになされたものであり、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を設置することができる機械室レスエレベータの改修方法を得ることを目的とする。   The present invention has been made to solve the above-described problems.

A machine equipped with an existing hoist for raising and lowering a weight, an upper support installed in the upper part of the hoistway, and an upper return wheel provided on the upper support and around which a suspension is wound A method of repairing a room-less elevator, the method including a step of removing the upper return wheel from the upper support and a step of installing a new hoisting machine on the upper support.

この発明の機械室レスエレベータの改修方法は、昇降路内の上部の返し車が配置されていた位置に新たな巻上機を設置するので、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を設置することができる。   The machine room-less elevator refurbishment method of the present invention installs a new hoisting machine at the position where the upper return wheel in the hoistway is arranged, so that many devices are diverted, and the mounting dimensions and external dimensions However, it is possible to install a hoisting machine different from that before the renovation.

さらに、巻上機５としては、軸方向寸法が軸方向に直角な方向の寸法よりも大きい胴長巻上機が用いられている。さらにまた、巻上機５は、真上から見て、その軸線がかご１の幅方向の中心線に対して傾斜するように配置されている。   Further, as the hoisting machine 5, a trunk hoisting machine having an axial dimension larger than a dimension in a direction perpendicular to the axial direction is used. Furthermore, the hoisting machine 5 is arranged such that its axis is inclined with respect to the center line in the width direction of the car 1 when viewed from directly above.

巻上機５は、真上から見て大部分がかご１と重なるように、かご１の後部の釣合おもり２が寄せられている側とは反対側の角部の真下に配置されている。但し、駆動シーブ７の懸架体３の引き出し部分は、真上から見てかご１と重なっていない。   The hoisting machine 5 is arranged directly below the corner opposite to the side where the counterweight 2 of the rear part of the car 1 is approached so that most of the hoisting machine 5 overlaps with the car 1 when viewed from directly above. . However, the drawer portion of the suspension body 3 of the drive sheave 7 does not overlap with the car 1 when viewed from directly above.

昇降路４内には、かご１の昇降を案内する第１及び第２のかごガイドレール８ａ，８ｂと、釣合おもり２の昇降を案内する第１及び第２の釣合おもりガイドレール９ａ，９ｂとが設置されている。かごガイドレール８ａ，８ｂは、かご１の前後方向（図１の上下方向）の中間部でかご１の両側に配置されている。   In the hoistway 4, first and second car guide rails 8 a and 8 b that guide the raising and lowering of the car 1, and first and second counterweight guide rails 9 a that guide the raising and lowering of the counterweight 2. 9b is installed. The car guide rails 8a and 8b are disposed on both sides of the car 1 at the middle part in the front-rear direction of the car 1 (vertical direction in FIG. 1).

かご１の下部には、第１及び第２のかご吊り車１１ａ，１１ｂが設けられている。釣合おもり２の上部には、釣合おもり吊り車１２が設けられている。かご吊り車１１ａ，１１ｂ及び釣合おもり吊り車１２は、それらの回転軸が水平、かつかご１の幅方向に直角となるように配置されている。   At the lower part of the car 1, first and second car suspension wheels 11a and 11b are provided. On the upper part of the counterweight 2, a counterweight suspension vehicle 12 is provided. The car suspension wheels 11 a and 11 b and the counterweight suspension vehicle 12 are arranged such that their rotation axes are horizontal and perpendicular to the width direction of the car 1.

昇降路４内の上部（頂部）には、上部支持体１３（図１では省略）が設置されている。上部支持体１３は、かごガイドレール８ａ，８ｂ及び釣合おもりガイドレール９ａ，９ｂにより支持されている。上部支持体１３には、上部返し車としてのかご返し車１４及び釣合おもり返し車１５が支持されている。   An upper support 13 (omitted in FIG. 1) is installed at the upper part (top) in the hoistway 4. The upper support 13 is supported by car guide rails 8a and 8b and counterweight guide rails 9a and 9b. A car return wheel 14 and a counterweight return wheel 15 as an upper return wheel are supported on the upper support 13.

かご返し車１４は、真上から見て、駆動シーブ７と第２のかご吊り車１１ｂとの間に配置されている。また、かご返し車１４は、その回転軸が水平、かつかご１の幅方向に平行となるように配置されている。   The car return wheel 14 is disposed between the drive sheave 7 and the second car suspension wheel 11b when viewed from directly above. In addition, the car return wheel 14 is arranged so that its rotation axis is horizontal and parallel to the width direction of the car 1.

In addition, the counterweight wheel 15 is arranged such that its rotation axis is horizontal and perpendicular to the width direction of the car 1.

上部支持体１３のかごガイドレール８ａ近傍には、かご側綱止め（図示せず）が設けられている。懸架体３の第１の端部は、かご側綱止めに接続されている。上部支持体１３の釣合おもり返し車１５と釣合おもりガイドレール９ａとの間の部分には、釣合おもり側綱止め１６が設けられている。懸架体３の第２の端部は、釣合おもり側綱止め１６に接続されている。   In the vicinity of the car guide rail 8 a of the upper support 13, a car side rope clamp (not shown) is provided. The first end of the suspension body 3 is connected to a car-side rope. A counterweight side rope clamp 16 is provided at a portion of the upper support 13 between the counterweight wheel 15 and the counterweight guide rail 9a. The second end portion of the suspension body 3 is connected to the counterweight side rope clamp 16.

懸架体３は、第１の端部側から順に、第１のかご吊り車１１ａ、第２のかご吊り車１１ｂ、かご返し車１４、駆動シーブ７、釣合おもり返し車１５及び釣合おもり吊り車１２に巻き掛けられている。即ち、図１及び図２のエレベータは、２：１ローピング方式のエレベータである。   The suspension body 3 includes, in order from the first end side, a first car suspension car 11a, a second car suspension car 11b, a car return wheel 14, a drive sheave 7, a counterweight return wheel 15, and a counterweight suspension. It is wrapped around the car 12. That is, the elevator shown in FIGS. 1 and 2 is a 2: 1 roping elevator.

図３は図２のかご返し車１４及び釣合おもり返し車１５の支持構造を示す概略の斜視図である。かご返し車１４は、かごガイドレール８ｂの近傍で上部支持体１３の下部に配置されている。上部支持体１３は、互いに間隔をおいて配置された第１及び第２の返し車梁１７ａ，１７ｂを有している。返し車梁１７ａ，１７ｂは、かご１の幅方向に平行、かつ水平に配置されている。釣合おもり返し車１５は、返し車梁１７ａ，１７ｂ間に配置されている。   FIG. 3 is a schematic perspective view showing a support structure for the car return wheel 14 and the counterweight return wheel 15 of FIG. The car return wheel 14 is disposed below the upper support 13 in the vicinity of the car guide rail 8b. The upper support 13 has first and second return wheels 17a and 17b that are spaced apart from each other. The return wheel beams 17a and 17b are arranged parallel to the width direction of the car 1 and horizontally. The counterweight return wheel 15 is disposed between the return beams 17a and 17b.

次に、上記のような既設の機械室レスエレベータの改修方法について説明する。図４は図１の機械室レスエレベータの改修後の状態を示す概略の平面図、図５は図４の機械室レスエレベータを示す概略の正面図である。実施の形態１の改修方法では、上部支持体１３から釣合おもり返し車１５を取り外し、上部支持体１３の釣合おもり返し車１５が取り付けられていた位置に新たな巻上機（上部巻上機）２１を設置する。   Next, a method for repairing the existing machine room-less elevator as described above will be described. 4 is a schematic plan view showing a state after the machine room-less elevator shown in FIG. 1 is repaired, and FIG. 5 is a schematic front view showing the machine room-less elevator shown in FIG. In the repair method of the first embodiment, the counterweight return wheel 15 is removed from the upper support 13, and a new hoisting machine (upper hoisting machine) is installed at the position where the counterweight return wheel 15 of the upper support 13 is attached. Machine) 21 is installed.

また、昇降路４の下部の巻上機（下部巻上機）５の駆動シーブ７を改修後のエレベータの下部返し車として使用する。さらに、昇降路４の下部の巻上機５からコイル部分を取り外して、駆動シーブ７の回転に対する磁気的な抵抗を無くす。即ち、改修後のエレベータでは、巻上機５は駆動力を発生せず、下部返し車としてのみ使用される。そして、新たな巻上機２１の駆動力により、かご１及び釣合おもり２が昇降する。   The drive sheave 7 of the hoisting machine (lower hoisting machine) 5 at the lower part of the hoistway 4 is used as a lower return wheel of the elevator after the repair. Further, the coil portion is removed from the hoisting machine 5 at the lower part of the hoistway 4 to eliminate magnetic resistance against the rotation of the drive sheave 7. That is, in the elevator after the modification, the hoisting machine 5 does not generate a driving force and is used only as a lower return wheel. Then, the car 1 and the counterweight 2 are moved up and down by the driving force of the new hoisting machine 21.

新たな巻上機２１は、軸方向寸法が軸方向に直角な寸法よりも小さい薄型巻上機である。また、新たな巻上機２１は、巻上機本体２２と駆動シーブ２３とを有している。巻上機本体２２は、駆動シーブ２３を回転させるモータと、駆動シーブ２３の回転を制動するブレーキとを有している。巻上機２１は、駆動シーブ２３の回転軸が水平、かつかご１の幅方向に直角となるように配置されている。   The new hoisting machine 21 is a thin hoisting machine whose axial dimension is smaller than the dimension perpendicular to the axial direction. Further, the new hoisting machine 21 has a hoisting machine main body 22 and a drive sheave 23. The hoisting machine body 22 includes a motor that rotates the drive sheave 23 and a brake that brakes the rotation of the drive sheave 23. The hoisting machine 21 is arranged so that the rotation shaft of the drive sheave 23 is horizontal and perpendicular to the width direction of the car 1.

懸架体３は、第１の端部側から順に、第１のかご吊り車１１ａ、第２のかご吊り車１１ｂ、かご返し車１４、駆動シーブ（下部返し車）７、新たな巻上機２１の駆動シーブ２３及び釣合おもり吊り車１２に巻き掛けられている。即ち、図４及び図５のエレベータも、２：１ローピング方式のエレベータである。   The suspension body 3 includes, in order from the first end side, a first car suspension car 11a, a second car suspension car 11b, a car return wheel 14, a drive sheave (lower return car) 7, and a new hoisting machine 21. The drive sheave 23 and the counterweight suspension wheel 12 are wound around. That is, the elevators of FIGS. 4 and 5 are also 2: 1 roping type elevators.

図６は図５の巻上機２１の支持構造を示す概略の斜視図である。巻上機本体２２は、第２の返し車梁１７ｂ上に支持されており、駆動シーブ２３は、返し車梁１７ａ，１７ｂ間の空間の真上に配置されている。これにより、懸架体３の駆動シーブ２３から下方へ向かう部分は、返し車梁１７ａ，１７ｂ間の空間を通っている。他の構成は、改修前と同様であるが、必要に応じて新たな機器と交換してもよい。   FIG. 6 is a schematic perspective view showing a support structure of the hoisting machine 21 of FIG. The hoisting machine main body 22 is supported on the second return beam 17b, and the drive sheave 23 is disposed directly above the space between the return wheels 17a and 17b. As a result, the portion of the suspension 3 that extends downward from the drive sheave 23 passes through the space between the return beams 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、昇降路４内の上部の釣合おもり返し車１５が配置されていた位置に新たな巻上機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 machine room-less elevator refurbishment method, the new hoisting machine 21 is installed at the position where the upper counterweight return wheel 15 in the hoistway 4 is disposed, so that many devices are diverted. The hoisting machine 21 having different mounting dimensions and external dimensions from those before the repair can be installed. 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、既設の巻上機５の駆動シーブ７を改修後のエレベータの下部返し車として使用するので、巻上機５の動力を切った後でも駆動シーブ７をそのまま残すことができ、廃棄物を削減することができる。   Furthermore, since the drive sheave 7 of the existing hoisting machine 5 is used as the lower return wheel of the elevator after the repair, the drive sheave 7 can be left as it is even after the hoisting machine 5 is turned off, and the waste Can be reduced.

さらにまた、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ので、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。   Furthermore, since the coil portion of the existing hoisting machine 5 is removed to eliminate the resistance, no extra load is applied even if the drive sheave 7 is used as a lower return wheel.

また、新たな巻上機２１として薄型巻上機を用いたので、釣合おもり返し車１５が設置されていたスペースに巻上機２１を容易に設置することができる。   Further, since a thin hoisting machine is used as the new hoisting machine 21, the hoisting machine 21 can be easily installed in the space where the counterweight wheel 15 is installed.

なお、図６では返し車梁１７ｂ上に巻上機２１が直接設置されているが、例えば図７に示すように、返し車梁１７ａ，１７ｂ間に一対の巻上機台２４ａ，２４ｂを架設し、巻上機台２４ａ，２４ｂ上に巻上機２１を設置してもよい。即ち、返し車梁１７ａ，１７ｂ上に巻上機台２４ａ，２４ｂを介して巻上機２１を設置してもよい。この場合、巻上機２１にかかる荷重を返し車梁１７ａ，１７ｂに分散して作用させ、返し車梁１７ａ，１７ｂに生じる応力を改修前に近くすることができる。   In FIG. 6, the hoisting machine 21 is directly installed on the return car beam 17b. For example, as shown in FIG. 7, a pair of hoisting machine tables 24a and 24b are installed between the return car beams 17a and 17b. The hoisting machine 21 may be installed on the hoisting machine bases 24a and 24b. That is, the hoisting machine 21 may be installed on the return wheels 17a and 17b via the hoisting machine bases 24a and 24b. In this case, the load applied to the hoisting machine 21 can be distributed and acted on the return wheel beams 17a and 17b, and the stress generated on the return wheel beams 17a and 17b can be made close to before the repair.

また、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。   In the above example, the hoisting machine 21 is installed so that the drive sheave 23 faces the car 1 side, but the drive sheave 23 faces the opposite side of 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.

さらに、上記の例では、釣合おもり返し車１５を新たな巻上機２１と交換したが、昇降路４の上部に配置された機器のレイアウトによっては、かご返し車１４を新たな巻上機２１と交換してもよい。
さらにまた、既設の巻上機５の駆動シーブ７を返し車として使用せず、巻上機５を撤去し、新たな返し車を昇降路４の下部に設置してもよい。
また、上記の例では、既設の巻上機５として胴長巻上機を示したが、既設の巻上機は薄型巻上機であってもよい。 Further, in the above example, the counterweight return wheel 15 is replaced with a new hoisting machine 21. However, depending on the layout of the equipment arranged on the upper part of the hoistway 4, the car return wheel 14 is replaced with a new hoisting machine. 21 may be exchanged.
