Description

【0001】
【発明の属する技術分野】
本発明は、乗りかごとつり合いおもりとのすれ違い時に発生する空気流の影響を低減するエレベータの空気整風装置に関する。
【0002】
【従来の技術】
近年、建物の高層化が益々進んでいるが、それに伴ってエレベータの高速化の要求も高まっている。
【0003】
しかし、エレベータの高速化に伴い、さまざまな問題が生じている。例えばかご走行時、乗りかごとつり合いおもりとのすれ違い時に発生する空気流の影響を受け、乗りかごが振動したり、不快な騒音が発する問題がある。
【0004】
そこで、従来、乗りかごの振動・騒音を極力低減するために、次のような対策技術が提案されている。
【0005】
図6は乗りかごに適用した従来の空気整風装置を説明する構成図である。
【0006】
同図において、1はエレベータ利用者を目的階に運ぶ乗りかご、2は乗りかご1の上部及び下部に設けられ、乗りかご1とつり合いおもり(図示せず)とのすれ違い時に発生する空気流を整風するかご整風装置である。
【0007】
このかご整風装置2は、乗りかご1を吊下するメインロープ3又は乗りかご1の底部に接続されるコンペンロープ4の通過部分に相当する個所にロープ通過口部が形成されている。さらに、かご整風装置2のロープ通過口部を通過するメインロープ3やコンペンロープ4の導出経路上に、ロープ3,4を両側から挟み込んで固定する一対のロープ固定板5,5´が設けられている。
【0008】
前記乗りかご1の上部に設置されるかご整風装置2は、図7に示すようにつり合いおもりとのすれ違い面側がほぼ垂直に突出された板体と、この突出板体の頂部からつり合いおもりのすれ違い面とは反対側方向に所定角度又は所要の曲面形状となるように下降傾斜され、この下降傾斜面にメインロープ3を通過させるロープ通過口部6が形成された下降傾斜板体とによって構成されている。一方、一対のロープ固定板5,5´は、複数本からなるメインロープ3を両側から挟み込み、図10に示すごとくボルト・ナット7により固定されている。8,8´はロープ固定板5,5´に当たって流れる空気流、9はかご上部のかご支持枠、10はスプリングである。
【0009】
次に、図8はつり合いおもりに従来の整風装置を適用した構成図である。
【0010】
同図において、11は乗りかご1との重量バランスをとるつり合いおもりであって、巻上機(図示せず)に掛け渡されたメインロープ3の一端側に乗りかご1が吊下され、他端側につり合いおもり11が吊下されている。このつり合いおもり11の上部及び下部には乗りかご1と同様におもり整風装置12が取り付けられている。さらに、おもり整風装置12のロープ通過口部を通過するメインロープ3やコンペンロープ4の導出経路上に、ロープ3,4を両側から挟み込んで固定する一対のロープ固定板13,13´が設けられている。
【0011】
このおもり整風装置12は、具体的には、図9に示すように、つり合いおもり11の上下部に取り付けられ、乗りかご1とのすれ違い面側がつり合いおもり11とほぼ同一面となるように突出された板体と、この突出板体の頂部から乗りかご1とのすれ違い面側とは反対側方向に所定角度又は所要の曲面形状となるように下降傾斜され、この下降傾斜面にロープ3,4を通過させるロープ通過口部14が形成された下降傾斜板体とにより構成されている。15,15´はロープ固定板13,13´に当たって流れる空気流、16はつり合いおもり上部のおもり支持枠、17はスプリングである。
【0012】
従って、以上のように乗りかご1の上下部にかご整風装置2、つり合いおもり11の上下部におもり整風装置12を取り付ける場合、他の機器との干渉やスペース等の制約から、整風装置2,12内にロープ固定板5,5´、13,13´が収納できない場合が多く、結局、整風装置2,12の外部に突出させた状態でロープ固定板5,5´、13,13´が取り付けられている。
【0013】
【発明が解決しようとする課題】
従って、以上のようにエレベータの空気整風装置では、複数本からなるメインロープ3、コンペンロープ4を固定するロープ固定板5,5´、13,13´の取り付けは、上下方向に延在する各ロープ3,4に対し、ほぼ直交するごとく水平に突出させた状態でロープ固定板5−5´、13−13´を取り付けることから、乗りかご1とつり合いおもり11とのすれ違い時に発生する空気流が一対のロープ固定板5−5´、13−13´に直接当たり、振動、騒音等の発生原因となっている。また、ロープ固定板5−5´、13−13´は、振動、騒音等の発生原因だけでなく、展望用エレベータの場合には外観上、見栄えが悪いなどの問題がある。
【0014】
本発明は上記事情に鑑みてなされたもので、ロープ固定板との一体化を図り、乗りかごとつり合いおもりとのすれ違い時に発生する空気流がロープ固定板に影響されないようにし、よって振動・騒音を低減化するエレベータの空気整風装置を提供できる。
【0015】
【課題を解決するための手段】
上記課題を解決するために、本発明に係るエレベータの空気整風装置は、乗りかご及びつり合いおもりの何れか一方又は両方の上下部に設けられ、乗りかご、つり合いおもりに接続されるロープの通過部分にロープ通過口部が形成され、すれ違い時に発生する空気流を、すれ違い面側とは反対側の方向に流す整風装置本体と、この整風装置本体のロープ通過口部に嵌合され、当該ロープ通過口部を通過するロープを両側から挟み込む一対のロープ固定板体とを設けた構成である。
【0016】
この発明は以上のような構成とすることにより、整風装置本体のロープ通過口部にロープを両側から挟み込む一対のロープ固定板体を嵌め込む構成としたので、従来のように乗りかごとつり合いおもりとのすれ違い時に発生する空気流がロープ固定板体に当たって乱流を発生する問題がなくなり、ひいては振動・騒音を低減化することが可能となる。
【0017】
なお、前記整風装置本体としては、乗りかご、つり合いおもりのすれ違い面側が上下方向に突出させた突出板体と、この突出板体の頂部から前記すれ違い面側とは反対側の方向に所定角度又は所要の曲面形状をもって下降傾斜され、ロープ通過部分にロープ開口部を形成した下降傾斜板体とで構成すれば、乗りかごとつり合いおもりとのすれ違い時に発生する空気流が下降傾斜板体及び一対のロープ固定板体上面をにそって流れるので、乗りかごとつり合いおもりとの間に入り込む空気量が少なくなり、その大半が乗りかごとつり合いおもりとの外側に振分けられるので、益々乗りかごの振動を低減でき、またロープ固定板体にぶつかる空気流の騒音も低減することが可能となる。
【0018】
さらに、前記一対のロープ固定板体としては、当該固定板体の面が下降傾斜板体とほぼ同一の面位置となるようにロープ開口部に嵌合するので、乗りかごとつり合いおもりとのすれ違い時に発生する空気流がロープ固定板体に影響されずに下降傾斜板体にそって流すことが可能となる。
【0019】
さらに、一対のロープ固定板体としては、ロープ開口部の少なくとも上辺面部及び下辺面部に対する面部側に弾性体を貼り付けるか、或いはロープ固定板体全体をロープの振れによる外力を吸収する部材で形成すれば、ロープの振れによる振動を含む外力を吸収するので、整風装置本体,ひいては乗りかごやつり合いおもりに伝達されないので、益々振動を低減化できる。
【0020】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参照して説明する。
【0021】
(第1の実施の形態)
図1及び図2は乗りかごに本発明に係るエレベータの空気整風装置の一実施の形態を適用した図であって、図1は乗りかごを含む整風装置の外観斜視図、図2は図1に示す整風装置の具体的な構成図である。なお、これらの図において、前述する図6及び図7と同一部分には同一符号を付して説明する。
【0022】
これらの図において、1はエレベータ利用者を目的階に運ぶ乗りかごであって、この乗りかご1の上部及び下部にかご整風装置が設けられている。
【0023】
このかご用整風装置は、乗りかご1を吊下する少なくとも1本以上のメインロープ3や乗りかご1の下部からつり合いおもりの底部に接続される少なくとも1本以上のコンペンロープ3の通過部分にロープ通過口部6を形成され、乗りかご1が乗りかご昇降時やつり合いおもりのすれ違い時に発生する空気流を当該つり合いおもり側とは反対側に導くように作用するかご整風装置本体21と、図2に示すように当該ロープ通過口部6に嵌合可能に設けられ、ロープ通過口部6を通過するロープ例えば4を両側から挟み込むとともにロープ通過口部6を閉塞するための一対のロープ固定板22,22´とにより構成されている。
【0024】
前記かご整風装置本体21は、具体的には、図2に示すようにつり合いおもりとのすれ違い面側が少なくとも上方にほぼ垂直に突出する突出板体21aと、この突出板体21aの頂部からつり合いおもりとのすれ違い面とは反対側方向に所定角度又は曲面形状をもって下降傾斜する下降傾斜板体21bとを有し、さらに必要に応じて突出板体21a及び下降傾斜板体21bで形成される空間部両側面側に不要な空気流が入り込まないように閉塞されている。そして、下降傾斜板体21bのロープ通過口部周辺相当の裏面側には断面L字状の固定板抱き込み部材21cが取り付けられている。この固定板抱き込み部材21cは、下降傾斜板体21bに形成されるロープ通過口部のうち、少なくとも上辺面周縁部側と下辺面周縁部側に取り付けられるが、ロープ通過口部周縁部全周にわたって下降傾斜板体21bの裏面側に設けてもよい。
【0025】
前記一対のロープ固定板22,22´は、その上面が下降傾斜板体21bとほぼ同一面となるように嵌合され、各ロープ固定板22,22´の対峙面側には、通過するロープ3,4の本数に応じた半円状や半楕円状のロープ挿通孔が形成され、さらに少なくともロープ固定板22の少なくとも上辺面部側に弾性体23、下傾斜面側に位置するロープ固定板22´の少なくとも下辺面部にも同様に弾性体23´が貼り付けられている。
【0026】
なお、一対のロープ固定板22,22´の対峙面側を除く各周辺面部に弾性体23、23´を貼り付けた構成であってもよい。
【0027】
なお、弾性体23、23´はロープ3,4の振動を吸収する機能をものであるが、例えば弾性体23、23´なしでロープ固定板22,22´全体を例えば木製片、ゴム、樹脂、或いはスポンジ等のごとき外力を吸収する部材を用いてもよい。
【0028】
同中、24はつり合いおもりのすれ違い時に発生する空気流、25はかご上部のかご支持枠、26はスプリングである。
【0029】
従って、以上のような実施の形態によれば、つり合いおもりのすれ違い面と反対方向に下降傾斜する下降傾斜板体21aを設けているので、つり合いおもりとのすれ違い時に発生する空気流24が乗りかごのすれ違い面と反対側である下降傾斜板体21aにそってかご外に流れるので、従来のように一対のロープ固定板が直接空気流を受けることがなくなり、よって空気流24が乱れることがなくなり、つり合いおもりとのすれ違い時の振動・騒音を低減化することができる。
【0030】
また、一対のロープ固定板22,22´は、その上面が下降傾斜板体21bとほぼ同一面となるように取り付けることにより、従来のようにロープ固定板による影響が全くなくなる。
【0031】
さらに、一対のロープ固定板22,22´に周面部分に弾性体23,23´を貼り付けるとか、或いは一対のロープ固定板22,22´全体を木製片、ゴム、樹脂、或いはスポンジ等のごとき外力を吸収する部材を用いれば、ロープ4,5の振動によって外力が加わった場合であっても、ロープ振動によるこすれ音を小さくできる。
【0032】
さらに、展望用エレベータの場合でも、外観上、美観を損なうことがなくなる。
【0033】
(第2の実施の形態)
図3及び図4はつり合いおもりに本発明に係るエレベータの空気整風装置の一実施の形態を適用した図であって、図3はつり合いおもりを含む整風装置の外観斜視図、図4は図3に示す整風装置の具体的な構成図である。なお、これらの図において、前述する図8及び図9と同一部分には同一符号を付して説明する。
【0034】
これらの図において、11は乗りかご1との重量バランスをとるつり合いおもりであって、巻上機(図示せず)に掛け渡されたメインロープ3の一端側に乗りかご1が吊下され、他端側につり合いおもり11が吊下されている。このつり合いおもり11の上部及び下部にも乗りかご1と同様におもり整風装置が取り付けられている。
【0035】
このおもり整風装置は、具体的には、図4に示すように、つり合いおもり11の上下部に取り付けられ、つり合いおもり11がつり合いおもり昇降時や乗りかご1のすれ違い時に発生する空気流を当該乗りかご1側とは反対側方向に導くように作用するおもり整風装置本体31と、このおもり整風装置本体31のうち、つり合いおもり11を吊下する少なくとも1本以上のメインロープ3やつり合いおもり11の下部から乗りかご1の底部に接続される少なくとも1本以上のコンペンロープ4の通過部分にロープ通過口部14を形成するとともに、図4に示すように当該ロープ通過口部14に嵌着可能に設けられ、ロープ通過口部14を通過するロープ例えば3を両側から挟み込むとともにロープ通過口部14を閉塞するための一対のロープ固定板32,32´とにより構成されている。
【0036】
前記おもり整風装置本体31は、具体的には、図4に示すように乗りかご1とのすれ違い面側がやつり合いおもり11の面とほぼ同一面となるように上方にほぼ垂直に突出されている突出板体31aと、この突出板体31aの頂部から乗りかご1とは反対側方向に所定角度又は曲面形状をもって下降傾斜する下降傾斜板体31bとを有し、さらに必要に応じて突出板体31a及び下降傾斜板体31bで形成される空間の両側面側に不要な空気流が入り込まないように閉塞されている。
【0037】
前記一対のロープ固定板32,32´は、下降傾斜板体31bのロープ通過口部にゴムやスポンジ等の弾性体33、33´を介在させ、かつ、ロープ固定板上面が下降傾斜板体31bとほぼ同一面となるように嵌合し、内部に空気が進入しない構成となっている。各ロープ固定板32,32´の対峙面側には、通過するロープ3,4の本数に応じた半円状や半楕円状のロープ貫通孔が形成され、具体的には図5に示すように各ロープ固定板32,32´の対峙面側には円形又は楕円形を有する傾斜のロープ貫通孔が形成されている。
【0038】
なお、一対のロープ固定板32,32´は、下降傾斜板体31bに図2と同様な取り付け手段で取り付けてもよい。また、弾性体33、33´は、ロープ3,4の振動を吸収する機能をものであるが、例えば弾性体33、33´なしでロープ固定板32,32´全体を例えば木製片、ゴム、樹脂、或いはスポンジ等のごとき外力を吸収する部材を用いてもよい。
【0039】
同中、34は乗りかご1のすれ違い時に発生する空気流、35はおもり支持枠、36はスプリングである。
【0040】
従って、以上のような実施の形態によれば、乗りかごのすれ違い面と反対方向に下降傾斜する下降傾斜板体31aを設けているので、乗りかご1とのすれ違い時に発生する空気流34が乗りかごのすれ違い面と反対側方向に延在する下降傾斜板体31aにそっておもり外に流れるので、従来のように一対のロープ固定板が直接空気流を受けることがなくなり、よって空気流34の乱れがなくなり、乗りかごとのすれ違い時に生じる振動・騒音を低減化できる。
【0041】
また、一対のロープ固定板32,32´は、その上面が下降傾斜板体31bとほぼ同一面となるように取り付けるので、従来のようにロープ固定板による乱流の影響が全くなくなる。
【0042】
さらに、一対のロープ固定板42,22´に周面部分に弾性体43,43´を貼り付けるとか、或いは一対のロープ固定板32,32´全体を木製片、ゴム、樹脂、或いはスポンジ等のごとき外力を吸収する部材を用いれば、ロープ3,4の振動によって外力が加わった場合であっても、ロープ振動によるこすれ音を小さくできる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioner for an elevator, which reduces the influence of an air flow generated when a car and a counterweight pass each other.
[0002]
[Prior art]
2. Description of the Related Art In recent years, as buildings are becoming higher and higher, demands for higher speed elevators are increasing.
[0003]
However, various problems have arisen with the increase in speed of elevators. For example, when the car is running, there is a problem that the car is vibrated and unpleasant noise is generated due to the influence of the airflow generated when the car and the counterweight pass each other.
[0004]
Therefore, conventionally, the following countermeasures have been proposed in order to reduce the vibration and noise of the car as much as possible.
[0005]
FIG. 6 is a configuration diagram illustrating a conventional air conditioner applied to a car.
[0006]
In the figure, reference numeral 1 denotes a car for carrying an elevator user to a destination floor, and 2 denotes a car provided at an upper portion and a lower portion of the car 1, and detects an air flow generated when the car 1 passes a counterweight (not shown). It is a cage air conditioner that regulates the wind.
[0007]
The car air conditioner 2 has a rope passage opening formed at a position corresponding to a passage of the compensating rope 4 connected to the main rope 3 for suspending the car 1 or the bottom of the car 1. Further, a pair of rope fixing plates 5 and 5 ′ that sandwich and fix the ropes 3 and 4 from both sides are provided on a lead-out path of the main rope 3 and the compensating rope 4 that pass through the rope passage opening of the car air conditioner 2. ing.
[0008]
As shown in FIG. 7, the car air conditioner 2 installed on the upper part of the car 1 has a plate body whose passing surface side is almost perpendicularly protruded from the balancing weight, and a balancing weight passing from the top of the protruding plate body. A downwardly inclined plate body which is inclined downward in a direction opposite to the surface so as to have a predetermined angle or a required curved surface shape, and on which a rope passage opening 6 for passing the main rope 3 is formed. ing. On the other hand, the pair of rope fixing plates 5, 5 'sandwich the main rope 3 composed of a plurality of ropes from both sides and are fixed by bolts and nuts 7 as shown in FIG. Numerals 8 and 8 'denote airflows hitting the rope fixing plates 5 and 5', 9 denotes a car support frame at the upper part of the car, and 10 denotes a spring.
[0009]
Next, FIG. 8 is a configuration diagram in which a conventional air conditioning device is applied to a counterweight.
[0010]
In the figure, reference numeral 11 denotes a counterweight which balances the weight of the car 1 and the car 1 is hung on one end side of a main rope 3 suspended over a hoist (not shown). A counterweight 11 is suspended from the end. A weight air conditioner 12 is attached to the upper and lower parts of the counterweight 11 as in the car 1. Further, a pair of rope fixing plates 13, 13 ′ for sandwiching and fixing the ropes 3, 4 from both sides are provided on the lead-out path of the main rope 3 and the compensating rope 4 passing through the rope passage opening of the weight air conditioner 12. ing.
[0011]
Specifically, as shown in FIG. 9, the weight air conditioner 12 is attached to the upper and lower portions of the counterweight 11, and protrudes so that the side passing the car 1 is substantially flush with the counterweight 11. From the top of the protruding plate to the side opposite to the side where the car 1 passes, so as to have a predetermined angle or a required curved shape. And a downwardly inclined plate body formed with a rope passage opening 14 through which the rope passes. Numerals 15 and 15 'denote airflows that impinge on the rope fixing plates 13 and 13', 16 a weight support frame above the counterweight, and 17 a spring.
[0012]
Therefore, when the car air conditioner 2 is mounted on the upper and lower portions of the car 1 and the weight air conditioner 12 is mounted on the upper and lower portions of the counterweight 11 as described above, the air conditioner 2, In many cases, the rope fixing plates 5, 5 ′, 13, 13 ′ cannot be accommodated in the rope 12, and after all, the rope fixing plates 5, 5 ′, 13, 13 ′ are projected outside the air conditioners 2, 12. Installed.
[0013]
[Problems to be solved by the invention]
Accordingly, as described above, in the elevator air conditioner, the attachment of the rope fixing plates 5, 5 ', 13, 13' for fixing the plurality of main ropes 3 and compensating ropes 4 is performed in the vertically extending manner. Since the rope fixing plates 5-5 ′ and 13-13 ′ are attached to the ropes 3 and 4 so as to protrude horizontally so as to be substantially perpendicular to each other, the air flow generated when the car 1 and the counterweight 11 pass each other is generated. Directly hit the pair of rope fixing plates 5-5 'and 13-13', causing vibration, noise, and the like. Further, the rope fixing plates 5-5 'and 13-13' not only cause vibration and noise, but also have a problem such as poor appearance in the case of a prospective elevator.
[0014]
The present invention has been made in view of the above circumstances, and is intended to be integrated with a rope fixing plate so that an airflow generated when the vehicle and a counterweight pass each other is not affected by the rope fixing plate, and thus vibration and noise are reduced. It is possible to provide an air conditioning apparatus for an elevator that reduces the amount of air.
[0015]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, an air conditioning apparatus for an elevator according to the present invention is provided at the upper and lower portions of one or both of a car and a counterweight, and a car passing part of a rope connected to the car and the counterweight. A rope passage opening is formed in the air conditioning device main body, which allows the air flow generated at the time of passing in the direction opposite to the passing surface side to be fitted to the rope passage opening portion of the air conditioning device main body, and the rope passage is provided. In this configuration, a pair of rope fixing plates sandwiching a rope passing through the mouth from both sides is provided.
[0016]
Since the present invention is configured as described above, the pair of rope fixing plates that sandwich the rope from both sides is fitted into the rope passage opening of the air conditioner main body. This eliminates the problem of the turbulent flow caused by the airflow generated when the airflow passes through the rope fixing plate, and thus the vibration and noise can be reduced.
