Description

本発明は、昇降路内のガイドレールに沿って乗りかごと釣合いおもりが移動するエレベーター装置に関するものである。   The present invention relates to an elevator apparatus in which a car and a counterweight move along a guide rail in a hoistway.

従来から、乗りかご及び釣合いおもりを、３：１ローピング又は４：１ローピングで吊り下げたエレベーター装置が提案されており、例えば、下記特許文献１には、駆動シーブ，吊り車及び返し車について、様々な大きさの組合せが記載されている。   Conventionally, an elevator apparatus in which a passenger car and a counterweight are suspended by 3: 1 roping or 4: 1 roping has been proposed. For example, in Patent Document 1 below, a drive sheave, a suspended wheel, and a return wheel are Various size combinations are described.

特開２００５−２００２０５号（図１〜図１３）Japanese Patent Laying-Open No. 2005-200205 (FIGS. 1 to 13)

一般に、乗りかご吊り車へ至るロープの固有振動数は、そのロープの長さ（乗りかごの位置）により変化し、乗りかごが最下階にあるとき最小となる。ここで、ロープの固有振動数の最小値は、ロープのストロークが増加するにつれて小さくなる。つまり、高層ビルに設置されるエレベーター装置に比べて、標準的な高さの建屋に設置されるエレベーター装置の方が、ロープの固有振動数の最小値が大きくなるので、駆動シーブの僅かな偏心などに起因して発生する振動の周波数と一致する可能性は少ない。   In general, the natural frequency of the rope leading to the car suspension vehicle varies depending on the length of the rope (the position of the car), and is minimum when the car is on the lowest floor. Here, the minimum value of the natural frequency of the rope decreases as the stroke of the rope increases. In other words, compared to an elevator device installed in a high-rise building, the elevator device installed in a standard height building has a smaller minimum value of the natural frequency of the rope, so the drive sheave is slightly eccentric. There is little possibility of coincident with the frequency of vibration generated due to the above.

しかしながら、上記特許文献１に記載されたエレベーター装置のように、３：１ローピングや４：１ローピングの場合、２：１ローピングの場合と比べて、巻上機の駆動シーブの回転数が大きいため、駆動シーブに発生する振動の周波数も大きい。従って、標準的な高さの建屋に設置されるエレベーター装置であっても、駆動シーブの振動の周波数が、ロープの固有振動数の最小値以上になる場合があり、その場合は、駆動シーブの振動の周波数とロープの固有振動数とが一致して共振を生じてしまう。   However, as in the elevator apparatus described in Patent Document 1, in the case of 3: 1 roping or 4: 1 roping, the rotational speed of the drive sheave of the hoisting machine is larger than in the case of 2: 1 roping. The frequency of vibration generated in the drive sheave is also large. Therefore, even in an elevator apparatus installed in a standard height building, the vibration frequency of the drive sheave may be equal to or greater than the minimum value of the natural frequency of the rope. The vibration frequency and the natural frequency of the rope coincide with each other to cause resonance.

また、上記特許文献１に記載されたエレベーター装置では、駆動シーブから、他の返し車を介することなく、乗りかご吊り車へロープが巻き掛けられているため、駆動シーブの振動が、乗りかご吊り車へ至るロープに直接伝わるようになっている。従って、駆動シーブの振動の周波数が、乗りかご吊り車へ至るロープの固有振動数と一致する場合は、必然的に、乗りかご吊り車へ至るロープと共振し、大きな振動が乗りかごに伝わってしまう。   Moreover, in the elevator apparatus described in the above-mentioned Patent Document 1, since the rope is wound from the driving sheave to the car suspension without passing through another return wheel, the vibration of the driving sheave is suspended from the car. It is transmitted directly to the rope leading to the car. Therefore, if the vibration frequency of the drive sheave matches the natural frequency of the rope that leads to the car suspension car, it inevitably resonates with the rope that leads to the car suspension car, and a large vibration is transmitted to the car. End up.

本発明の目的は、乗りかごの振動を抑制したエレベーター装置を提供することである。   The objective of this invention is providing the elevator apparatus which suppressed the vibration of the passenger car.

上述の目的を達成するために、本発明のエレベーター装置は、昇降路内でロープにより吊られた乗りかごと釣合いおもりが巻上機により駆動されるエレベーター装置において、前記乗りかご及び釣合いおもりはｎ：１（ｎは３以上の自然数）ローピングで吊られており、前記乗りかご及び釣合いおもりに設けられた吊り車と、前記昇降路内に設けられ前記ロープを方向転換させる返し車と、前記巻上機に設けられ前記ロープが巻き掛けられる駆動シーブを備え、この駆動シーブから前記乗りかごの吊り車へ至るまでに前記ロープが巻き掛けられる返し車のうち少なくとも１つと、前記釣合いおもり吊り車が前記駆動シーブの１.２〜１.３倍の直径を、他は前記駆動シーブと略同じ又は前記駆動シーブの１.２〜１.３倍の直径を有し、前記返し車，乗りかご吊り車及び釣合いおもり吊り車は、前記駆動シーブと略同じ直径のものと前記駆動シーブよりも大きい直径のものとの２種類の直径からなるようにしたものである。

以下、本発明の実施形態について、図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

本実施形態のエレベーター装置では、乗りかご１が、乗りかごガイドレールに沿って昇降し、釣合いおもり１２が、釣合いおもりガイドレールに沿って昇降するように構成されている。また、乗りかご１と釣合いおもり１２は、ロープ５により吊られ、駆動シーブ１１を有する胴長巻上機１０により駆動される。ここで、胴長の巻上機とは、回転軸方向の寸法が、回転軸方向と垂直方向の寸法よりも大きい巻上機をいう。 A lift device of the present embodiment, the car 1 is moved up and down along car guide rails, counterweight 12 is configured to lift along a counterweight guide rail. The car 1 and the counterweight 12 are suspended by a rope 5 and are driven by a trunk hoisting machine 10 having a drive sheave 11. Here, the trunk length hoisting machine refers to a hoisting machine whose dimension in the rotation axis direction is larger than the dimension in the direction perpendicular to the rotation axis direction.

更に、乗りかご１の乗場側には出入口２が設けられ、天井部にはかご上枠３が設置され、このかご上枠３に、駆動シーブ１１と略同じ直径を有する乗りかご吊り車８が取付けられている。また、乗りかご１の右側部のかご床付近にはかご下プーリ６が設けられ、かご床中央付近の下方には綱止め４が設けられている。ここで、乗りかご１の右側部とは、エレベーターの乗場側から見て乗りかご１の右の部分を意味する。一方、釣合いおもり１２の上部にも、綱止め１５及び釣合いおもり吊り車１３が取付けられている。尚、綱止め４，１５は、ロープ５の伸びを吸収する機能を有している。   Further, an entrance 2 is provided on the landing side of the car 1, and a car upper frame 3 is installed on the ceiling, and a car suspension vehicle 8 having substantially the same diameter as the drive sheave 11 is placed on the car upper frame 3. Installed. Further, a car lower pulley 6 is provided near the car floor on the right side of the car 1, and a leash 4 is provided below the car floor center. Here, the right side of the car 1 means the right part of the car 1 when viewed from the elevator landing side. On the other hand, a leash 15 and a counterweight suspension wheel 13 are also attached to the upper portion of the counterweight 12. The leashes 4 and 15 have a function of absorbing the elongation of the rope 5.

そして、昇降路の上部には、互いの鉛直投影が略平行な乗りかご側返し車７ａ及び７ｂと巻上機側返し車９ａが設置されている。更に昇降路の上部には、この乗りかご側返し車７ａ及び７ｂの鉛直投影に対して傾斜するように配置された巻上機側返し車９ｂと、上記乗りかご側返し車７ａ等の鉛直投影に対して略垂直に配置された釣合いおもり側返し車
１４が設置されている。 In the upper part of the hoistway, there are installed car-side return wheels 7a and 7b and a hoisting machine-side return wheel 9a whose vertical projections are substantially parallel to each other. Further, on the upper part of the hoistway, the hoisting machine-side return wheel 9b arranged so as to be inclined with respect to the vertical projection of the car-side return wheels 7a and 7b, and the vertical projection of the above-mentioned car-side return wheel 7a, etc. A counterweight return wheel 14 arranged substantially perpendicular to the counterweight 14 is installed.

尚、本実施形態では、吊り車，返し車，シーブ，プーリを総称して滑車と呼び、乗りかご１又は釣合いおもり１２の上部又は側部に取付けられる滑車を吊り車、昇降路に取付けられる滑車を返し車，駆動滑車をシーブ，乗りかご１又は釣合いおもり１２に取付けられる吊り車以外の滑車をプーリとしている。また、巻上機側返し車とは、乗りかご吊り車８又は釣合いおもり吊り車１３から胴長巻上機１０の駆動シーブ１１へ至るまでにロープ５が巻き掛けられる返し車を指す。また、乗りかご側返し車とは、乗りかご吊り車８を基準として駆動シーブ１１と反対側に位置する返し車を指す。更に、釣合いおもり側返し車とは、釣合いおもり吊り車１３を基準として駆動シーブ１１と反対側に位置する返し車を指す。   In the present embodiment, the suspension wheel, the return wheel, the sheave, and the pulley are collectively referred to as a pulley, and the pulley that is attached to the top or side of the car 1 or the counterweight 12 is a suspension wheel and the pulley that is attached to the hoistway. A pulley other than a suspension vehicle attached to the car 1 or the counterweight 12 is used as a pulley. The hoisting machine side return wheel refers to a return wheel on which the rope 5 is wound from the car suspension car 8 or the counterweight suspension car 13 to the drive sheave 11 of the trunk hoisting machine 10. The car-side return wheel refers to a return wheel located on the opposite side of the drive sheave 11 with respect to the car suspension vehicle 8. Furthermore, the counterweight side return wheel refers to a return wheel located on the opposite side of the drive sheave 11 with respect to the counterweight suspension wheel 13.

次に、本実施形態のエレベーター装置におけるロープ５の掛け方について説明する。基本的には、本実施形態のエレベーター装置は、綱止め４，１５と、乗りかご吊り車８及び釣合いおもり吊り車１３を利用して、乗りかご１と釣合いおもり１２を吊る、３：１ローピング方式を採用している。具体的には図１に示す通りであり、まず、ロープ５の一端が、乗りかご１の床下付近の綱止め４に固定され、この綱止め４から略水平に伸びてかご下プーリへ至り、このかご下プーリ６で上方へ方向転換される。そして、乗りかご側返し車７ａから略水平に伸びてもう一つの乗りかご側返し車７ｂに至り、この乗りかご側返し車７ｂによって下方へ方向転換される。更に、このロープ５は、乗りかご１の上部の乗りかご吊り車８を介して上方へ方向転換し、巻上機側返し車９ａに巻き掛けられ下方へ方向転換された後、もう一つの巻上機側返し車９ｂに巻き掛けられて再度上方へ方向転換し、胴長巻上機１０の駆動シーブ１１に巻き掛けられて下方へ方向転換する。更に、このロープ５は、釣合いおもり１２の上部の釣合いおもり吊り車１３を介して上方へ方向転換され、釣合いおもり側返し車１４を介して下方へ方向転換された後、釣合いおもり１２の上部の綱止め１５に至り、この綱止め１５にロープ５の一端が固定される。   Next, how to hang the rope 5 in the elevator apparatus of the present embodiment will be described. Basically, the elevator apparatus of the present embodiment suspends the car 1 and the counterweight 12 using the leashes 4 and 15, the car suspension vehicle 8 and the counterweight suspension vehicle 13, and 3: 1 roping. The method is adopted. Specifically, as shown in FIG. 1, first, one end of the rope 5 is fixed to the leash 4 near the floor of the car 1, and extends substantially horizontally from the leash 4 to the pulley under the car. The direction is changed upward by the lower pulley 6 of the car. Then, the car-side return wheel 7a extends substantially horizontally to reach another car-side return wheel 7b, and is turned downward by the car-side return wheel 7b. Further, the rope 5 changes its direction upward via a car suspension car 8 at the upper part of the car 1, and is wound around the hoisting machine side return wheel 9a and turned downward. It is wound around the upper machine-side return wheel 9b and turns upward again, and is wound around the drive sheave 11 of the trunk length hoisting machine 10 and turns downward. Further, the rope 5 is turned upward through the counterweight suspension wheel 13 at the upper portion of the counterweight 12, and is turned downward through the counterweight-side return wheel 14, and then the upper portion of the counterweight 12. A rope clamp 15 is reached, and one end of the rope 5 is fixed to the rope clamp 15.

上述のような本実施形態によれば、３：１ローピングであるため、懸垂荷重が３つのロープに分散され、返し車への懸垂荷重が低減され、また、胴長巻上機１０のトルクが小さくて済む。つまり、エレベーター装置の強度部材や胴長巻上機１０の小型化が可能となるので、製作コストを低減すると共に省スペース化の効果が期待できる。   According to the present embodiment as described above, because of 3: 1 roping, the suspension load is distributed to the three ropes, the suspension load to the return wheel is reduced, and the torque of the trunk hoisting machine 10 is reduced. It's small. That is, since the strength member of the elevator apparatus and the lengthwise hoisting machine 10 can be reduced in size, it is possible to reduce the manufacturing cost and to save space.

また、巻上機側返し車９ａ，９ｂを設けることにより、乗りかご１，釣合いおもり１２及び胴長巻上機１０のレイアウトの変更が容易となり、昇降路平面の配置を工夫すれば省スペース化も実現できる。更に、駆動シーブ１１寄りの巻上機返し車９ｂの配置を調整すれば、駆動シーブ１１へのロープ５の巻付角も適宜変更できる。
更に、上述のローピング構成では、駆動シーブ１１に対してロープ５が一重巻され、その巻付角が略１８０°となっているので、駆動シーブ１１への巻付角が大きくなる二重巻を採用した場合と比べて、駆動シーブ１１の軸への荷重が低く抑えられる。その結果、駆動シーブ１１の振動を小さくできるため、ロープ５及び乗りかご吊り車８を介して乗りかご１に伝わる振動や、返し車を介して建屋に伝わる振動を抑制できる。 Further, by providing the hoisting machine side return wheels 9a and 9b, the layout of the car 1, the counterweight 12 and the trunk hoisting machine 10 can be easily changed, and the space can be saved by devising the arrangement of the hoistway plane. Can also be realized. Furthermore, if the arrangement of the hoisting wheel return wheel 9b near the drive sheave 11 is adjusted, the winding angle of the rope 5 around the drive sheave 11 can be changed as appropriate.
Furthermore, in the above-described roping configuration, the rope 5 is wound once around the drive sheave 11 and the winding angle is approximately 180 °. Therefore, the double winding that increases the winding angle around the drive sheave 11 is performed. Compared with the case where it is adopted, the load on the shaft of the drive sheave 11 can be kept low. As a result, since the vibration of the drive sheave 11 can be reduced, vibration transmitted to the car 1 via the rope 5 and the car suspension vehicle 8 and vibration transmitted to the building via the return wheel can be suppressed.

次に、各滑車の大きさについて説明する。まず、かご下プーリ６，乗りかご吊り車８，巻上機側返し車９ｂ，釣合いおもり側返し車１４は、駆動シーブ１１と略同じ直径を有している。一方、乗りかご側返し車７ａ及び７ｂ，巻上機側返し車９ａ，釣合いおもり吊り車１３は、駆動シーブ１１等と異なる直径を有している。尚、略同じ直径とは、厳密に同径のものに限らず、設計誤差の範囲を含むものとし、異なる直径とは、例えば、駆動シーブ等の直径の１.２〜１.３倍のものとする。ここで、駆動シーブ１１よりも小さな滑車を設けていないのは、ロープ５の寿命を可能な限り長く保つためである。また、駆動シーブ１１の直径を小さくしたのは、直径の大きな駆動シーブ１１は巻上機の大型化につながり製作費が増加すること等が理由である。また、駆動シーブ１１等よりも大きい直径として複数の種類のものを用いても良いが、製作性を考慮すると、駆動シーブ１１を含むすべての滑車の直径は、駆動シーブ１１と略同じ直径のものと、駆動シーブ１１よりも大きい直径のものとの２種類を使い分けるのが望ましい。   Next, the size of each pulley will be described. First, the car lower pulley 6, the car suspension car 8, the hoisting machine side return wheel 9 b, and the counterweight side return wheel 14 have substantially the same diameter as the drive sheave 11. On the other hand, the car-side return wheels 7a and 7b, the hoisting machine-side return wheel 9a, and the counterweight suspension wheel 13 have different diameters from the drive sheave 11 and the like. The substantially same diameter is not limited to the exact same diameter, but includes a range of design errors, and the different diameter is, for example, 1.2 to 1.3 times the diameter of a drive sheave or the like. To do. Here, a pulley smaller than the drive sheave 11 is not provided in order to keep the life of the rope 5 as long as possible. The diameter of the drive sheave 11 is reduced because the drive sheave 11 having a larger diameter leads to an increase in the hoisting machine and an increase in production costs. A plurality of types of diameters larger than the drive sheave 11 may be used. However, in consideration of manufacturability, all pulleys including the drive sheave 11 have substantially the same diameter as the drive sheave 11. It is desirable to use two types, one having a diameter larger than that of the drive sheave 11.

更に、乗りかご１の昇降速度に対する各滑車の周速度について説明する。ここで、各滑車とロープ５との間に滑りが生じていない場合は、各滑車の周速度は、各滑車におけるロープ５の速度と一致するが、実際は僅かながら滑りが発生する可能性があるので、厳密には異なることが考えられる。従って、本実施形態では、周速度の違いがロープ５の滑りによる微差の範囲内であって実質的に同じ周速度とみなせる場合を、略同じ周速度と呼ぶことにする。すると、かご下プーリ６，乗りかご側返し車７ａ及び７ｂ、釣合いおもり側返し車１４は、その周速度が乗りかご１の昇降速度と略同じとなる。また、乗りかご吊り車８，釣合いおもり吊り車１３は、その周速度が乗りかご１の昇降速度の略２倍となり、駆動シーブ１１，巻上機側返し車９ａ及び９ｂは、その周速度が乗りかご１の昇降速度の略３倍となる。


Furthermore, the peripheral speed of each pulley with respect to the raising / lowering speed of the car 1 will be described. Here, when there is no slip between each pulley and the rope 5, the peripheral speed of each pulley coincides with the speed of the rope 5 in each pulley, but in reality, a slight slip may occur. So, strictly speaking, it can be considered different. Therefore, in this embodiment, the case where the difference in the peripheral speed is within the range of the slight difference due to the slip of the rope 5 and can be regarded as substantially the same peripheral speed will be referred to as substantially the same peripheral speed. Then, the car lower pulley 6, the car-side return wheels 7a and 7b, and the counterweight-side return wheel 14 have substantially the same peripheral speed as the raising / lowering speed of the car 1. In addition, the circumferential speed of the car suspension car 8 and the counterweight suspension car 13 is approximately twice the ascending / descending speed of the car 1, and the driving sheave 11 and the hoisting machine side return wheels 9a and 9b have a circumferential speed of approximately 1. This is approximately three times the lifting speed of the car 1.


そして、上述した各滑車の大きさ及び周速度によって、各滑車の回転数が必然的に定まり、駆動シーブ１１の回転数に対する他の滑車の回転数は、次の通りとなる。まず、駆動シーブ１１と略同じ直径の滑車については、巻上機側返し車９ｂの回転数が駆動シーブ
１１の回転数の略１倍、乗りかご吊り車８の回転数が駆動シーブ１１の回転数の略0.50倍、釣合いおもり側返し車１４及びかご下プーリ６の回転数が駆動シーブ１１の回転数の略０.３３ 倍である。そして、駆動シーブ１１よりも大きな滑車については、巻上機側返し車９ａの回転数が駆動シーブ１１の回転数の０.７０〜０.８３倍、釣合いおもり吊り車
１３の回転数が駆動シーブ１１の回転数の０.３８〜０.４２倍、乗りかご側返し車７ａ及び７ｂの回転数が駆動シーブ１１の回転数の０.２６〜０.２８倍である。 The rotational speed of each pulley is inevitably determined by the size and peripheral speed of each pulley described above, and the rotational speeds of the other pulleys with respect to the rotational speed of the drive sheave 11 are as follows. First, for a pulley having the same diameter as that of the drive sheave 11, the rotation speed of the hoisting machine-side return wheel 9 b is approximately one time the rotation speed of the drive sheave 11, and the rotation speed of the car suspension car 8 is the rotation of the drive sheave 11. The rotational speed of the counterweight side return wheel 14 and the lower pulley 6 of the counterweight is approximately 0.50 times the number, and approximately 0.33 times the rotational speed of the drive sheave 11. For the pulley larger than the drive sheave 11, the rotational speed of the hoisting machine side return wheel 9a is 0.70 to 0.83 times the rotational speed of the drive sheave 11, and the rotational speed of the counterweight suspension wheel 13 is the drive sheave. The rotational speed of the car sheave return wheels 7a and 7b is 0.26 to 0.28 times the rotational speed of the drive sheave 11.

このように、エレベーター装置を構成する上で必要となる、吊り車，返し車，シーブ，プーリとして、２種類の大きさの滑車を使い分ける場合においても、上述のように大きい滑車を小さい滑車の１.２〜１.３倍程度とすれば、周速度の異なる滑車同士で回転数が一致することはない。また、同じ周速度の滑車が複数存在するような場合（例えば、乗りかご吊り車８と釣合いおもり吊り車１３，乗りかご側返し車７ａ及び７ｂと釣合いおもり側返し車１４）であっても、上述のように直径を異ならせれば、回転数の一致を避けることができる。そして、滑車の回転数の一致を避けることにより、滑車の偏心などによる振動の同期を防ぐことが可能となる。   As described above, even when two types of pulleys are used properly as a suspension wheel, a return wheel, a sheave, and a pulley, which are necessary for configuring the elevator apparatus, the large pulley is replaced with the small pulley 1 as described above. If it is about 2 to 1.3 times, the number of revolutions does not coincide between pulleys having different peripheral speeds. Even when there are a plurality of pulleys having the same peripheral speed (for example, the car suspension car 8 and the counterweight suspension car 13, the car side return cars 7a and 7b, and the counterweight side return car 14), If the diameters are made different as described above, it is possible to avoid the coincidence of the rotation speeds. By avoiding the coincidence of the rotation speeds of the pulleys, it is possible to prevent the synchronization of vibration due to the eccentricity of the pulleys.

更に、駆動シーブ１１は、他の滑車と比べて振動を発生しやすいので、特に駆動シーブ１１の回転数と一致する滑車を少なくすることが重要である。従って、本実施形態の巻上機側返し車９ａ及び９ｂのように、駆動シーブ１１と同じ周速度となる返し車が複数存在するような場合であっても、そのうち少なくとも１つを駆動シーブ１１と異なる直径にすれば、駆動シーブ１１の回転数と一致する滑車の数を少なくでき、駆動シーブ１１の振動との同期を抑制することが可能である。   Furthermore, since the drive sheave 11 is more likely to generate vibrations than other pulleys, it is particularly important to reduce the number of pulleys that match the rotational speed of the drive sheave 11. Therefore, even when there are a plurality of return wheels having the same peripheral speed as the drive sheave 11 as in the hoisting machine side return wheels 9a and 9b of this embodiment, at least one of them is the drive sheave 11 If the diameter is different from that of the drive sheave 11, the number of pulleys that matches the rotation speed of the drive sheave 11 can be reduced, and synchronization with vibration of the drive sheave 11 can be suppressed.

また、本実施形態のような３：１ローピングのエレベーター装置の場合、駆動シーブ
１１の僅かな偏心などに起因して発生する振動の周波数が高いため、標準的な高さの建屋に設置されたとしても、その周波数が、乗りかご吊り車８へ至るロープ５の固有振動数と一致する可能性がある。しかしながら、本実施形態では、駆動シーブ１１から乗りかご吊り車８へロープ５が至るまでに、巻上機側返し車９ａが設けられており、しかもその回転数が駆動シーブ１１の回転数と異なっている。したがって、駆動シーブ１１で発生した振動は、巻上機側返し車９ａによってその成分が変化し、ロープ５の固有振動数と一致するのを避けることが可能になる。その結果、ロープ５が共振するのを防ぎ、乗りかご吊り車８を介して乗りかご１に大きな振動が伝わるのを抑制することができる。 Further, in the case of the elevator apparatus of 3: 1 roping as in the present embodiment, the vibration frequency generated due to slight eccentricity of the drive sheave 11 is high, so it was installed in a standard height building. Even so, the frequency may coincide with the natural frequency of the rope 5 leading to the car suspension vehicle 8. However, in the present embodiment, the hoisting machine side return wheel 9 a is provided from the drive sheave 11 to the car suspension vehicle 8 until the rope 5 reaches, and the rotation speed is different from the rotation speed of the drive sheave 11. ing. Therefore, the vibration generated in the drive sheave 11 can be prevented from changing its component due to the hoisting machine side return wheel 9 a and matching the natural frequency of the rope 5. As a result, it is possible to prevent the rope 5 from resonating and to prevent a large vibration from being transmitted to the car 1 through the car suspension wheel 8.

尚、上述の実施形態では、３：１ローピングのエレベーター装置について説明したが、４：１ローピングなど、ｎ：１ローピング（ｎは３以上の自然数）であっても良い。例えば、乗りかご１及び釣合いおもり１２の上部に吊り車が複数設けられているようなエレベーター装置では、３：１ローピングの場合よりも更に多くの滑車が存在する。しかし、上述のように、回転数が一致する滑車の組合せを少なくすれば、振動の同期を防ぐことができ、乗りかご１での振動や騒音の抑制が可能となる。尚、昇降路に取付けられる返し車や駆動シーブ１１の振動の同期を防ぐことは、建屋での振動や騒音の抑制にもつながる。また、駆動シーブ１１から乗りかご１の吊り車へロープ５が至るまでに、駆動シーブ１１と直径を異にする返し車を設けることにより、駆動シーブ１１の振動の周波数がロープ５の固有振動数と一致するのを防ぐことができる。   In the above-described embodiment, the elevator apparatus with 3: 1 roping has been described. However, n: 1 roping (n is a natural number of 3 or more) such as 4: 1 roping may be used. For example, in an elevator apparatus in which a plurality of suspension vehicles are provided above the car 1 and the counterweight 12, there are more pulleys than in the case of 3: 1 roping. However, as described above, if the number of pulley combinations having the same number of rotations is reduced, vibration synchronization can be prevented, and vibration and noise in the car 1 can be suppressed. It should be noted that preventing synchronization of vibrations of the return wheel and the drive sheave 11 attached to the hoistway leads to suppression of vibration and noise in the building. Further, by providing a return wheel having a diameter different from that of the drive sheave 11 before the rope 5 reaches the suspension car of the car 1 from the drive sheave 11, the frequency of the vibration of the drive sheave 11 is the natural frequency of the rope 5. Can be prevented from matching.

図３は本発明の第２の実施形態を示すエレベーター装置の斜視図であり、図４は図３のロープ５の掛け方を示す図である。   FIG. 3 is a perspective view of an elevator apparatus showing a second embodiment of the present invention, and FIG. 4 is a diagram showing how the rope 5 of FIG. 3 is hung.

本実施形態のエレベーター装置は、釣合いおもり１２が出入口２と反対の後ろ側に配置された、所謂後ろ落ちタイプである。また、胴長巻上機１０の軸が出入口２に対して垂直方向に位置しており、昇降路上部の巻上機側返し車９ａ及び釣合いおもり側返し車１４の配置が、上述の第１の実施形態と異なると共に、新たに巻上機側返し車９ｃが追加されている。尚、この巻上機側返し車９ｃは、駆動シーブ１１よりも大きな直径、具体的には、駆動シーブ１１の１.２〜１.３倍の直径を有している。   The elevator apparatus according to the present embodiment is a so-called rear falling type in which the counterweight 12 is disposed on the rear side opposite to the entrance 2. Further, the shaft of the trunk hoisting machine 10 is positioned in the vertical direction with respect to the entrance 2, and the arrangement of the hoisting machine side return wheel 9 a and the counterweight side return wheel 14 at the upper part of the hoistway is the first described above. In addition to this embodiment, a hoisting machine side return wheel 9c is newly added. The hoisting machine-side return wheel 9c has a diameter larger than that of the drive sheave 11, specifically, 1.2 to 1.3 times that of the drive sheave 11.

このように、本実施形態では、第１の実施形態に対して更に巻上機側返し車９ｃが追加されているので、レイアウト変更の自由度が一層高くなる。また、巻上機側返し車９ｃの追加により全体の滑車の数が増加するが、巻上機側返し車９ｃの回転数は、駆動シーブ
１１の回転数の０.７０〜０.８３倍であるため、滑車の中で最も振動を発生しやすい駆動シーブ１１の振動との同期が抑制できる。 Thus, in this embodiment, since the winding machine side return wheel 9c is further added with respect to 1st Embodiment, the freedom degree of a layout change becomes still higher. Further, the addition of the hoisting machine side return wheel 9c increases the total number of pulleys, but the rotation speed of the hoisting machine side return wheel 9c is 0.70 to 0.83 times the rotation speed of the drive sheave 11. Therefore, synchronization with the vibration of the drive sheave 11 that is most likely to generate vibrations in the pulley can be suppressed.

尚、上述の第１，２の実施形態では、同じ周速度の滑車が３つ以上存在する場合がある。例えば、第１の実施形態では、駆動シーブ１１と略同じ周転数の滑車は、駆動シーブ
１１を含めて巻上機側返し車９ａ及び９ｂの合計３つ存在し、第２の実施形態では、駆動シーブ１１と略同じ周速度の滑車は、駆動シーブ１１を含めて巻上機側返し車９ａ，９ｂ及び９ｃの合計４つ存在する。しかしながら、第１の実施形態では、大きい滑車の数が２つ、小さい滑車の数が１つ、第２の実施形態では、大きい滑車の数が２つ、小さい滑車の数が２つであり、大きい滑車の数と小さい滑車の数が近い値となっているため、回転数の偏りが抑えられる。つまり、大きい滑車の数と小さい滑車の数の差が、０又は１となるように設定すれば、製作性の観点から滑車の大きさが２種類であったとしても、回転数の偏りが抑えられ、振動の影響を低下させることができる。 In the first and second embodiments described above, there may be three or more pulleys having the same peripheral speed. For example, in the first embodiment, there are a total of three pulleys of the hoisting machine side return wheels 9a and 9b including the drive sheave 11, and there are a total of three pulleys having the same number of revolutions as the drive sheave 11. There are a total of four pulleys including the drive sheave 11 and the hoisting machine side return wheels 9a, 9b, and 9c. However, in the first embodiment, the number of large pulleys is two and the number of small pulleys is one. In the second embodiment, the number of large pulleys is two and the number of small pulleys is two. Since the number of large pulleys and the number of small pulleys are close to each other, uneven rotation speed can be suppressed. In other words, if the difference between the number of large pulleys and the number of small pulleys is set to 0 or 1, even if there are two types of pulleys from the viewpoint of manufacturability, the rotational speed deviation is suppressed. The influence of vibration can be reduced.
