Description

本発明は、乗りかごの側部両側をロープで吊り上げ、かつ、乗りかご側と釣り合い重り側のローピングが異なる比からなる機械室レスエレベーターに関する。   The present invention relates to a machine room-less elevator in which both sides of a side of a car are lifted by a rope, and the roping on the car side and the balance weight side have different ratios.

従来のエレベーターとして、例えば、図３、図４に示すようなもの（例えば、特許文献１参照）がある。図３は従来の機械室レスエレベーターの平面図、図４は図３の正面図である。   Examples of conventional elevators include those shown in FIGS. 3 and 4 (see, for example, Patent Document 1). FIG. 3 is a plan view of a conventional machine room-less elevator, and FIG. 4 is a front view of FIG.

図３、図４において、１は乗りかご２と釣り合い重り３が昇降する昇降路壁面、４はロープ、５、６は転向プーリ、８は昇降路頂部に設けられ転向プーリ５、６を支持するビーム、９は電動機、１０は釣り合い重り３に設けられるプーリ、１１はロープ４の一端が固定されるロープ固定端、１２は点検台、１３は点検台１２に設けられる柵、１４は制御盤、１５は金属帯、７１は綱車、７２は転向プーリを示している。   3 and 4, 1 is a hoistway wall surface on which the car 2 and the counterweight 3 are raised and lowered, 4 is a rope, 5 and 6 are turning pulleys, and 8 is provided at the top of the hoistway to support the turning pulleys 5 and 6. Beam, 9 is an electric motor, 10 is a pulley provided on the counterweight 3, 11 is a rope fixed end to which one end of the rope 4 is fixed, 12 is an inspection table, 13 is a fence provided on the inspection table 12, 14 is a control panel, Reference numeral 15 denotes a metal belt, 71 denotes a sheave, and 72 denotes a turning pulley.

上記、従来のエレベーターは、乗りかご２の上部にロープ４が接続され、転向プーリ５、６を介して綱車７１、転向プーリ７２に至っている。更に、ロープ４は綱車７１に巻き付けられて電動機９の駆動力により、プーリ７２を経由して釣り合い重り３のプーリ１０に至り、端部は点検台１２のロープ固定端１１に至るようになっている。   In the above-described conventional elevator, the rope 4 is connected to the upper part of the car 2 and reaches the sheave 71 and the turning pulley 72 via the turning pulleys 5 and 6. Further, the rope 4 is wound around the sheave 71 and reaches the pulley 10 of the counterweight 3 via the pulley 72 by the driving force of the electric motor 9, and the end reaches the rope fixed end 11 of the inspection table 12. ing.

ここで、乗りかご２と電動機９の間のローピング比は１：１であり、電動機９と釣り合い重り３とのローピング比は２：１である。前者のローピング比は後者のローピング比より低いため、鉛直方向の移動量は乗りかご２に比べ，釣り合い重り３の移動量は少なくなる。このため、釣り合い重り３の上部に釣り合い重り３が移動しない空間が捻出され、この空間を電動機や制御盤を設置できる等価的な機械室空間として利用可能となる。
特開２０００−３５１５５２号公報 Here, the roping ratio between the car 2 and the electric motor 9 is 1: 1, and the roping ratio between the electric motor 9 and the counterweight 3 is 2: 1. Since the former roping ratio is lower than the latter roping ratio, the amount of movement in the vertical direction is smaller than that of the car 2, and the amount of movement of the counterweight 3 is smaller. For this reason, a space where the counterweight 3 does not move is twisted above the counterweight 3, and this space can be used as an equivalent machine room space in which an electric motor and a control panel can be installed.
JP 2000-351552 A

前記従来技術においては、建物の屋上に機械室はないが、乗りかご鉛直投影上部に乗りかご２に一端を締結されたロープ４を受けるプーリ５、６が必要であり、そのプーリ５、６を支持するためのビーム８も同様に不可欠であった。このため乗りかご上部隙間を確保するために、オーバーヘッド寸法をプーリ５、６およびビーム８の設置分、大きくとらざるを得なかった。また、上記従来のエレベーターにおいては、乗りかご鉛直投影でない箇所に点検台１２を配し、制御盤１４および電動機９を設置し機械室と等価的な機械室空間を確保しているため、ピット寸法の更なる縮小は困難であると考えられる。 In the prior art, there is no machine room on the roof of the building, but pulleys 5 and 6 for receiving the rope 4 fastened at one end to the car 2 are necessary on the upper part of the car vertical projection. A supporting beam 8 was likewise essential. For this reason, in order to secure a clearance at the upper part of the car, the overhead size has to be largely increased by the installation amount of the pulleys 5 and 6 and the beam 8. Further, in the above-described conventional elevator, the inspection table 12 is arranged at a place where the car is not vertically projected, the control panel 14 and the electric motor 9 are installed, and a machine room space equivalent to the machine room is secured. It is considered difficult to further reduce this.

本発明の目的は、乗りかご上下に有効なスペースをより多く確保するとともに、乗りかごのサイズに対して必要最小限の昇降路寸法で据付や保守・点検が可能な機械室レスエレベーターを提供することにある。   An object of the present invention is to provide a machine room-less elevator that can secure more effective space above and below the car and can be installed, maintained, and inspected with the minimum hoistway dimensions relative to the size of the car. There is.

本発明は上記目的を達成するために、巻上機により乗りかご側部両側をロープで吊り上げ駆動するようにした機械室レスエレベーターにおいて、前記ロープを左右に配置し、この左右のロープを個別にプーリおよび転向プーリを介して巻上機に掛け、前記乗りかご側を１：１のローピング比とし、次に、前記巻上機に掛けられた後の左右のロープを一組として釣合い重り側を２：１のローピング比となるよう構成し、かつ、前記巻上機および前記プーリと前記転向プーリの配置位置を、乗りかご鉛直投影外となるようにしたことを特徴とする。   In order to achieve the above object, the present invention provides a machine room-less elevator in which both sides of a car are lifted and driven by a hoisting machine, and the ropes are arranged on the left and right sides, and the left and right ropes are individually connected. Hang on a hoisting machine via a pulley and a turning pulley, the car side has a roping ratio of 1: 1, and then the right and left ropes after being hung on the hoisting machine are set as one set and the counterweight side is It is configured to have a roping ratio of 2: 1, and the arrangement position of the hoisting machine, the pulley, and the turning pulley is outside the vertical projection of the car.

本発明の請求項１によれば、乗りかご上部および下部に従来の構造と比較して大きなスペースを確保することが可能であり、オーバーヘッド寸法の縮小、ピット寸法の短縮、更には乗りかご上下の機器配置が容易となり、組立や点検保守時間の短縮化が図れる。   According to claim 1 of the present invention, it is possible to secure a large space in the upper and lower parts of the car as compared with the conventional structure, the overhead dimension is reduced, the pit dimension is shortened, and further, the upper and lower parts of the car are Equipment arrangement becomes easy, and assembly and inspection maintenance time can be shortened.

また、請求項２においては、かご投影面積外で、かつ、一対のかご用ガイドレールおよび一対の釣り合い重り用ガイドレールにより構成される平面内にプーリを配置することから、昇降路寸法の省スペース化が可能となる。   According to the second aspect of the present invention, the pulley is disposed outside the projected area of the car and in a plane constituted by the pair of car guide rails and the pair of counterweight guide rails. Can be realized.

以下、本発明になる機械室レスエレベーターの実施形態を図に基き説明する。   Hereinafter, an embodiment of a machine room-less elevator according to the present invention will be described with reference to the drawings.

図１は本発明の一実施形態になる機械室レスエレベーターの平面図、図２は図１の正面図である。   FIG. 1 is a plan view of a machine room-less elevator according to an embodiment of the present invention, and FIG. 2 is a front view of FIG.

図１、図２において、乗りかご１０２および釣り合い重り１０３は昇降路１０１を昇降する。図示はしていないが、乗りかご１０２および釣り合い重り１０３の側面には，上下にガイド装置が取り付けられており、そのガイド装置により乗りかご１０２は乗りかご用ガイドレール１０４ａ、ｂに沿って昇降する。釣り合い重り１０３もそれと同様に、釣り合い重り用ガイドレール１０５ａ、ｂに沿って，かごを傾かせることなく滑らかに昇降路を昇降する。   1 and 2, a car 102 and a counterweight 103 move up and down the hoistway 101. Although not shown, guide devices are vertically attached to the side surfaces of the car 102 and the counterweight 103, and the car 102 moves up and down along the car guide rails 104a and 104b. . Similarly, the counterweight 103 moves up and down smoothly along the counterweight guide rails 105a and 105b without tilting the car.

また、乗りかご１０２はその重心付近の両側側部をロープ１０６ａ、ｂ（ここでは左右に一本づつ表示したが通常ロープは左右に複数本ある）の端部を固定するロープヒッチ１０７ａ、ｂにより直接，もしくは固定用機器を介して締結されている。このロープ１０６ａ、ｂは、その鉛直上方にあるプーリ１０８ａ、ｂに巻き回され、それと同じ高さにあり，水平方向位置の異なるプーリ１０９ａ、ｂまで巻き伸ばされる。そして、鉛直下方に設けられた転向プーリ１１０ａ、ｂを経て，巻上機１１１と一体であるシーブ１１２に巻き掛けられる。このため、乗りかご１０２は１：１のローピング比で昇降する。   Also, the car 102 is provided with rope hitches 107a and 107b that fix the ends of the ropes 106a and b near the center of gravity of the car 102 (in this case, one rope is shown on the left and right, but there are usually multiple ropes on the left and right). It is fastened directly or via a fixing device. The ropes 106a and 106b are wound around pulleys 108a and 108b that are vertically above them, and are wound at the same height as the pulleys 109a and 109b at different horizontal positions. And it winds around the sheave 112 integral with the hoisting machine 111 through the turning pulleys 110a and 110b provided vertically below. For this reason, the car 102 moves up and down at a roping ratio of 1: 1.

一方、シーブ１１２に巻き掛けられたロープ１０６ａ、ｂは１組にまとめられ、その鉛直延長上にある釣り合い重り１０３の上部に設置されたプーリ１１３を介し、昇降路頂部に端部を固定するためのロープヒッチ１１４により直接，もしくは固定用機器を介して締結されている。このため、釣り合い重り側は２：１のローピング比となる。   On the other hand, the ropes 106a and 106b wound around the sheave 112 are combined into one set, and the end is fixed to the top of the hoistway through the pulley 113 installed on the upper part of the counterweight 103 on the vertical extension. It is fastened by the rope hitch 114 directly or via a fixing device. For this reason, the counterweight side has a roping ratio of 2: 1.

また、前記巻上機１１１および前記プーリ１０８ａ、ｂとプーリ１０９ａ、ｂ並びに前記転向プーリ１１０ａ、ｂの配置位置を、乗りかご鉛直投影外となるようにしてある。   The arrangement position of the hoisting machine 111, the pulleys 108a and b, the pulleys 109a and b, and the turning pulleys 110a and 110b is outside the vertical projection of the car.

これらの構成により、乗りかご１０２上部および下部に従来の構造と比較して大きなスペースを確保することが可能であり、オーバーヘッド寸法の縮小、ピット寸法の短縮、更には乗りかご１０２上下の機器配置が容易となり、組立や点検保守時間の短縮化を図ることができる。   With these configurations, it is possible to secure a large space in the upper and lower parts of the car 102 as compared with the conventional structure, and the overhead dimension is reduced, the pit dimension is shortened, and the equipment arrangement above and below the car 102 is reduced. As a result, assembly and inspection maintenance time can be shortened.

更に、プーリ１０８ａ、ｂとプーリ１０９ａ、ｂ並びに前記転向プーリ１１０ａ、ｂを、一対の乗りかご用ガイドレール１０４ａ、ｂおよび一対の釣り合い重り用ガイドレール１０５ａ、ｂにより構成される平面内に配置することにより、昇降路寸法の省スペース化が可能となる。   Further, the pulleys 108a and 108b, the pulleys 109a and 109b, and the turning pulleys 110a and 110b are arranged in a plane constituted by a pair of car guide rails 104a and 104b and a pair of counterweight guide rails 105a and 105b. As a result, the space for the hoistway can be saved.

更に又、乗りかご用ガイドレール１０４ａ、ｂと釣り合い重り用ガイドレール１０５ａ、ｂのレールゲージを同じ寸法としたため、転向プーリ１１０ａ、ｂ及び巻上機１１１等を余裕をもって釣り合い重り用ガイドレール１０５ａ、ｂ間に収めることができるばかりかガイドレールの据付が容易となる。   Furthermore, since the rail gauges of the car guide rails 104a and 104b and the counterweight guide rails 105a and 105b have the same dimensions, the turning pulleys 110a and 110b, the hoisting machine 111 and the like are provided with sufficient margins. In addition to being able to fit between b, the guide rail can be easily installed.
