国際公開第ＷＯ０４／０４１７０３号パンフレットInternational Publication No. WO04 / 041703 Pamphlet

前記の構成では、主ロープ１７の端部１８，１９を取り付けるための第３の支持梁１３が必要なため、コストアップの要因になっていた。また第３の支持梁１３を省略すると、主ロープ１７の端部１８，１９を第２の支持梁１２で片持ち支持しなければらならないので、支持梁１２などの強度アップが必要になる。
本発明はこの問題を解決することを目的としたものである。 In the above-described configuration, the third support beam 13 for attaching the end portions 18 and 19 of the main rope 17 is necessary, which increases the cost. If the third support beam 13 is omitted, the ends 18 and 19 of the main rope 17 must be cantilevered by the second support beam 12, so that the strength of the support beam 12 and the like needs to be increased.
The present invention aims to solve this problem.

本発明は、昇降路の上方に設置された機械室又は昇降路の上方に昇降路と連続して配置された機械室空間に設けられた支持梁によって支持された駆動装置，駆動シーブ及びそらせシーブと、前記駆動シーブ及びそらせシーブに巻き掛けられた主ロープと、吊りシーブを有し前記主ロープにより吊り下げられて昇降路内を昇降するかご及びカウンターウェイトとを備えたエレベータ装置において、前記支持梁は一対あり、昇降路平断面上で、前記駆動シーブ，そらせシーブ、かごの吊りシーブ及びカウンターウェイトの吊りシーブが前記一対の支持梁間で一直線上に配置されたものである。
更に本発明は、前記かごの吊りシーブに巻き掛けられた主ロープの反駆動装置側端部及び前記カウンターウェイトの吊りシーブに巻き掛けられた主ロープの反駆動装置側端部を、昇降路平断面上で、前記一対の支持梁上又は前記一対の支持梁間に配置したものである。 The present invention relates to a driving device, a driving sheave, and a deflecting sheave supported by a support beam provided in a machine room installed above a hoistway or in a machine room space arranged continuously above the hoistway. An elevator apparatus comprising: a main rope wound around the drive sheave and the deflecting sheave; a car having a suspension sheave and suspended by the main rope to move up and down in a hoistway; and a counterweight. There are a pair of beams, and the drive sheave, the baffle sheave, the car hanging sheave and the counterweight hanging sheave are arranged in a straight line between the pair of supporting beams on the hoistway flat section.
Furthermore, the present invention provides a hoistway flat portion for connecting the opposite end of the main rope wound around the suspension sheave of the car and the opposite end of the counter rope toward the suspension of the counterweight. On the cross section, it is arranged on the pair of support beams or between the pair of support beams.

本発明によれば、主ロープの端部を片持ちにすることなく、第３の支持梁を省略することができる。   According to the present invention, the third support beam can be omitted without cantilevering the end portion of the main rope.

本発明の実施の形態を図１により説明する。図に示すようにかご３の吊りシーブ５，駆動シーブ１５，そらせシーブ１６，カウンターウェイト６の吊りシーブ８が、平断面上で一直線に配置してある。これにより、主ロープ１７の端部１８，１９は共に第１，第２支持梁１１，１２の間にくる。そのため、第１，第２支持梁間に端部１８，１９用のブラケットなどを設置すればよい。
このように本実施の形態によれば、主ロープ１７の端部１８，１９を片持ちにすることなく、第３の支持梁１３を省略することができる。 An embodiment of the present invention will be described with reference to FIG. As shown in the drawing, the suspension sheave 5 of the car 3, the drive sheave 15, the deflecting sheave 16, and the suspension sheave 8 of the counterweight 6 are arranged in a straight line on the plane cross section. Thereby, both ends 18 and 19 of the main rope 17 are between the first and second support beams 11 and 12. Therefore, a bracket for the end portions 18 and 19 may be installed between the first and second support beams.
Thus, according to the present embodiment, the third support beam 13 can be omitted without making the end portions 18 and 19 of the main rope 17 cantilever.

図２はカウンターウェイト６がかご３の出入口３ａの側面側にくるレイアウトであるが、図１の場合と同様に、かご３の吊りシーブ５，駆動シーブ１５，そらせシーブ１６，カウンターウェイト６の吊りシーブ８を、平断面上で一直線に配置することにより、図１の場合と同じ効果を得ることができる。   FIG. 2 shows a layout in which the counterweight 6 is located on the side surface side of the entrance / exit 3a of the car 3. However, the suspension sheave 5, the driving sheave 15, the deflecting sheave 16, and the counterweight 6 of the car 3 are suspended as in the case of FIG. By arranging the sheave 8 in a straight line on the plane cross section, the same effect as in the case of FIG. 1 can be obtained.

前記の各実施の形態においては、かご３の吊りシーブ５，駆動シーブ１５，そらせシーブ１６，カウンターウェイト６の吊りシーブ８を、平断面上で一直線に配置している。このように配置すれば、主ロープ１７にロープドローが発生しない、即ち主ロープ１７に捻れが発生しないため、主ロープ１７のダメージが小さくて済むという効果がある。   In each of the above-described embodiments, the suspension sheave 5 of the car 3, the drive sheave 15, the deflecting sheave 16, and the suspension sheave 8 of the counterweight 6 are arranged in a straight line on the plane cross section. If arranged in this way, rope draw does not occur in the main rope 17, that is, the main rope 17 is not twisted, so that there is an effect that damage to the main rope 17 can be reduced.

しかし実際には、主ロープ１７の多少の捩れは許容できる場合が多い。このような場合には、主ロープ１７は一直線上にならなくても、その端部１８，１９が、昇降路平断面上で支持梁１１，１２上又は支持梁１１，１２の間に位置していれば、端部１８，１９を片持ちにすることなく第３の支持梁１３を省略することができる。
この場合、端部１８，１９の設置位置の自由度が高くなるため、かご３に対する吊りシーブ５、カウンターウェイト６に対する吊りシーブ８の取り付け角度の自由度が高くなるという効果がある。 In practice, however, some twisting of the main rope 17 is often acceptable. In such a case, even if the main rope 17 is not in a straight line, its end portions 18 and 19 are located on the support beams 11 and 12 or between the support beams 11 and 12 on the hoistway plane cross section. In this case, the third support beam 13 can be omitted without canting the end portions 18 and 19.
In this case, since the freedom degree of the installation position of the edge parts 18 and 19 becomes high, there exists an effect that the freedom degree of the attachment angle of the suspension sheave 5 with respect to the cage | basket | car 3 and the suspension sheave 8 with respect to the counterweight 6 becomes high.

例えば図１において、吊りシーブ８はカウンターウェイト６の重心を吊っているが、端部１８が第１，第２支持梁１１，１２の範囲内にある限り、吊りシーブ８がカウンターウェイト６の重心を吊った状態を保ちながら、カウンターウェイト６を図１上でもう少し上又は下に移動させることもできる。
これを図で説明すると、図３に示すように、吊りシーブを図１の８から図３の８ａに傾斜させることによって、カウンターウェイトを図１の６から図３の６ａにずらしたレイアウトに変更することができる。同様にカウンターウェイトを図の上方にずらすことや、かご３の吊りシーブ５を傾斜させることもできる。また図２の場合も同じである。更に第１，第２支持梁１１，１２の間隔も現場に応じて変更することができる。 For example, in FIG. 1, the suspended sheave 8 suspends the center of gravity of the counterweight 6, but as long as the end 18 is within the range of the first and second support beams 11, 12, the suspended sheave 8 is centered on the counterweight 6. The counterweight 6 can also be moved up or down slightly in FIG.
This is illustrated in the figure. As shown in FIG. 3, the counterweight is changed from 6 in FIG. 1 to 6a in FIG. 3 by tilting the suspension sheave from 8 in FIG. 1 to 8a in FIG. can do. Similarly, the counterweight can be shifted upward in the drawing, and the hanging sheave 5 of the car 3 can be tilted. The same applies to the case of FIG. Furthermore, the distance between the first and second support beams 11 and 12 can also be changed according to the site.

前記の各実施の形態においては、支持梁１１，１２は昇降路の上方に設置された機械室又は昇降路の上方に昇降路と連続して配置された機械室空間に設けているが、明確な機械室又は機械室相当空間がなくても、単に昇降路の上方部に支持梁を設置するものであれば、本発明を適用できる。   In each of the above-described embodiments, the support beams 11 and 12 are provided in a machine room installed above the hoistway or in a machine room space arranged continuously above the hoistway. Even if there is no machine room or machine room-equivalent space, the present invention can be applied as long as the support beam is simply installed above the hoistway.
