Description

本発明は、昇降路上部に架設される支持梁により乗かご及びつり合いおもりに接続されたロープを吊り滑車及び吊りロッドを介して支持するエレベータ装置にあって、吊りロッドから支持梁に伝達する振動を低減するエレベータ吊りロッド防振装置の取付け方法に関するものである。   The present invention relates to an elevator apparatus that supports a rope connected to a passenger car and a counterweight by means of a support beam erected at the upper part of a hoistway via a suspension pulley and a suspension rod, and vibrations transmitted from the suspension rod to the support beam. The present invention relates to a method for mounting an elevator hanging rod vibration isolator that reduces noise.

多くのエレベータ装置は、乗かごの昇降移動を案内する乗かごガイドレール、及びつり合いおもりの昇降移動を案内するつり合いおもり用ガイドレールの上端側に支持梁を備え、この支持梁により乗かご及びつり合いおもりに接続されたロープを吊り滑車及び吊りロッドを介して支持する構造となっている。このため、支持梁には吊りロッドから乗かご及びつり合いおもりの昇降動作に伴う振動が伝達する。この振動は支持梁からガイドレール、ガイドレールからレールブラケットを介して建築物へ伝わり、特に、昇降路に居室などが隣接している場合は、騒音被害を招く要因となる。したがって、吊りロッドから支持梁に伝わる振動を可能な限り低減することが望ましい。そこで、従来、吊り滑車を支持している支持梁とその吊り滑車を吊るための吊りロッドとの連結部に弾性体を配置し、支持梁や建築物への振動の伝達を低減するものが提案されている（例えば、特許文献１、２参照）。
特許第３３９７７３３号 特開２００６−１８２４９１号公報 Many elevator apparatuses are provided with a support beam on the upper end side of a car guide rail for guiding the lifting and lowering movement of the car and a counterweight guide rail for guiding the lifting and lowering movement of the counterweight. The rope connected to the weight is supported via a suspension pulley and a suspension rod. For this reason, the vibration accompanying the raising / lowering operation of the passenger car and the counterweight is transmitted from the suspension rod to the support beam. This vibration is transmitted from the support beam to the building via the guide rail and from the guide rail to the building, and particularly when a living room or the like is adjacent to the hoistway, it causes noise damage. Therefore, it is desirable to reduce vibration transmitted from the suspension rod to the support beam as much as possible. Therefore, conventionally, an elastic body is arranged at the connecting part between the support beam supporting the suspension pulley and the suspension rod for hanging the suspension pulley to reduce the transmission of vibration to the support beam and the building. (For example, see Patent Documents 1 and 2).
Japanese Patent No. 3398733 JP 2006-182491 A

前述した従来の方法により振動の低減を図ることができるが、稀に建築物の構造により吊りロッドからの振動が支持梁、次いで建築物に伝わり、さらならなる振動の低減が望まれる場合がある。しかしながら、従来のものでは、既設のエレベータ装置にあって、振動低減のため支持梁と吊りロッドとの連結部に配置される弾性体をより振動吸収に優れたものに変更しようとした場合、吊りロッドに掛かる荷重を解除したうえで、吊りロッドを支持梁に固定するナット等を取外す必要があり、作業に多くの手間と時間を要するという問題があった。   Vibration can be reduced by the above-described conventional method. However, in some rare cases, vibration from the suspension rod is transmitted to the support beam and then to the building due to the structure of the building, and further vibration reduction may be desired. . However, in the conventional elevator apparatus, if the elastic body arranged at the connecting portion between the support beam and the suspension rod is to be changed to one having better vibration absorption in order to reduce vibrations, After releasing the load applied to the rod, it is necessary to remove a nut or the like for fixing the suspension rod to the support beam, and there is a problem that much work and time are required for the work.

本発明は、前述した従来技術における実状からなされたもので、その目的は、容易に振動伝達の低減を図ることのできるエレベータ吊りロッド防振装置の取付け方法を提供することにある。   The present invention has been made from the above-described prior art, and an object of the present invention is to provide an elevator hanging rod vibration isolator mounting method that can easily reduce vibration transmission.

前記目的を達成するために、本発明の請求項１に係る発明は、昇降路を昇降する乗かご及びつり合いおもりと、上下に延在するように前記昇降路に立設され、前記乗かごの昇降移動を案内する乗かごガイドレールと、上下に延在するように前記昇降路に立設され、前記つり合いおもりの昇降移動を案内するつり合いおもりガイドレールと、前記昇降路の上部に架設される支持梁と、前記乗かご及び前記つり合いおもりを吊るロープと、このロープが滑走自在に巻き掛けられる吊り滑車と、この吊り滑車を吊るとともに、前記支持梁に挿通される吊りロッドと、この吊りロッドに螺合され、前記吊りロッドを前記支持梁の上部にて固定するナットと、前記吊りロッドに挿通され、前記支持梁の上面と接するように配置される第１のプレートと、前記吊りロッドに挿通され、前記第１のプレートの上面と接するように配置される弾性体と、前記吊りロッドに挿通され、前記弾性体と前記ナットとの間に配置される第２のプレートと、前記吊りロッドに螺合され、前記ナットの上面に接するように配置されるロックナットとを有するエレベータ装置にあって、前記吊りロッドから前記支持梁に伝達する振動を低減するエレベータ吊りロッド防振装置の取付け方法おいて、前記ロックナットを前記吊りロッドから取外した後、その下面に前記ナットの外形寸法よりも大きな寸法を有する穴が形成されるスペーサを前記吊りロッド上端から挿通して前記ナットを覆うように配置し、次いで、追設弾性体を前記スペーサの上面に接するように配置し、この後、追設プレートを前記追設弾性体の上面に接するように配置し、次に、追設ナットを前記吊りロッドに螺合するとともに、この追設ナットを前記弾性体及び前記追設弾性体のそれぞれのたわみ量が規定値となるまで螺進させることを特徴としている。   In order to achieve the above object, an invention according to claim 1 of the present invention is characterized in that a car and a counterweight that elevate and lower the hoistway, and the hoistway so as to extend vertically, A car guide rail that guides up and down movement, a counterweight guide rail that stands up and down on the hoistway so as to extend up and down, and is installed on the upper part of the hoistway. A support beam, a rope for suspending the car and the counterweight, a suspension pulley on which the rope is slidably wound, a suspension rod for suspending the suspension pulley and being inserted into the support beam, and the suspension rod A nut that is screwed to the upper portion of the support beam; a first plate that is inserted through the suspension rod and disposed to contact the upper surface of the support beam; An elastic body that is inserted through the suspension rod and disposed so as to be in contact with the upper surface of the first plate; and a second plate that is disposed between the elastic body and the nut and is disposed through the suspension rod. An elevator apparatus having a lock nut screwed to the suspension rod and disposed so as to contact the upper surface of the nut, wherein the vibration is transmitted from the suspension rod to the support beam. In the method of attaching the device, after the lock nut is removed from the suspension rod, a spacer having a hole having a dimension larger than the outer dimension of the nut is formed on the lower surface of the lock nut from the upper end of the suspension rod. Then, the additional elastic body is disposed so as to contact the upper surface of the spacer, and then the additional plate is placed on the additional elastic body. Next, the additional nut is screwed onto the suspension rod, and the additional nut is screwed until the respective deflection amounts of the elastic body and the additional elastic body reach a specified value. It is characterized by letting.

本発明の請求項１に係る発明では、ロックナットを吊りロッドから取外した後、スペーサを吊りロッド上端から挿入し、このスペーサの下面に形成された穴に既設のナットを収納する。この状態で追設弾性体、次いで追設プレートを吊りロッドに挿通するとともに、追設ナットを螺合し、この追設ナットを既設の弾性体及び追設弾性体のそれぞれのたわみ量が規定値となるまで螺進させる。これにより既設のナットと第１のプレートとが離隔するとともに、追設ナットで荷重を受け、既設の弾性体及び追設弾性体のそれぞれにより振動が吸収されるようになる。このように、既設のナットを外すことなく、即ち、吊りロッドに荷重をかけたまま、追設弾性体を取付けることができ、これによって、容易に振動伝達の低減を図ることができる。   In the invention according to claim 1 of the present invention, after removing the lock nut from the suspension rod, the spacer is inserted from the upper end of the suspension rod, and the existing nut is stored in the hole formed in the lower surface of the spacer. In this state, the additional elastic body and then the additional plate are inserted into the suspension rod, the additional nut is screwed, and the deflection amount of the existing elastic body and the additional elastic body is determined by the specified value. Rotate until As a result, the existing nut and the first plate are separated from each other, and the load is received by the additional nut, and the vibration is absorbed by each of the existing elastic body and the additional elastic body. As described above, the additional elastic body can be attached without removing the existing nut, that is, while the load is applied to the suspension rod, and thus vibration transmission can be easily reduced.

また、本発明の請求項２に係る発明は、前記追設弾性体が、複数個重ねて配置されることを特徴としている。   The invention according to claim 2 of the present invention is characterized in that a plurality of the additional elastic bodies are arranged in a stacked manner.

本発明の請求項２に係る発明では、追設弾性体を複数個重ねて配置することにより、振動伝達をさらに低減することができる。   In the invention according to claim 2 of the present invention, the vibration transmission can be further reduced by arranging a plurality of the additional elastic bodies.

本発明によれば、追設弾性体を取付けるという簡易な構造で、建築物へ振動が伝達することを防止し、快適性の向上を図ることができるとともに、追設弾性体は、既設のナットを外すことなく、即ち、吊りロッドに荷重をかけたまま取付けることができることから、作業に要する労力及び時間を大幅に低減することができる。   According to the present invention, with a simple structure of attaching an additional elastic body, vibration can be prevented from being transmitted to the building, and the comfort can be improved. Since it can be attached without removing the load, that is, while the load is applied to the suspension rod, the labor and time required for the work can be greatly reduced.

以下、本発明のエレベータ吊りロッド防振装置の取付け方法に係る実施の形態を図に基づいて説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment according to a method for attaching an elevator hanging rod vibration isolator of the present invention will be described with reference to the drawings.

既設のエレベータ装置は図１、図２及び図３に示すように、昇降路１を昇降する昇降体、即ち、乗かご２及びつり合いおもり３と、レールブラケット４を介して昇降路壁１ａに取付けられ、昇降体２、３の昇降移動を案内するガイドレール５と、ガイドレール５の上部に架設される支持梁６と、乗かご２及びつり合いおもり３を吊るロープ７と、このロープ７が滑走自在に巻き掛けられる吊り滑車８と、この吊り滑車８を回転自在に軸支する支持体９と、この支持体９の左右２箇所にその下端が接続されるとともに、支持梁６に挿通される吊りロッド１０と、この吊りロッド１０に螺合され、吊りロッド１０を支持梁６の上部にて固定するナット１１と、吊りロッド１０に挿通され、支持梁６の上面と接するように配置される第１のプレート１２と、吊りロッド１０に挿通され、第１のプレート１２の上面と接するように配置される弾性体１３と、吊りロッド１０に挿通され、弾性体１３とナット１１との間に配置される第２のプレート１４と、吊りロッド１０に螺合され、ナット１１の上面に接するように配置されるロックナット１５と、吊りロッド１０の上端に取付けられる割りピン１６とを有している。   As shown in FIGS. 1, 2 and 3, the existing elevator apparatus is attached to the hoistway wall 1a via the hoisting body for raising and lowering the hoistway 1, that is, the car 2 and the counterweight 3, and the rail bracket 4. The guide rail 5 that guides the up-and-down movement of the elevating bodies 2 and 3, the support beam 6 installed on the upper portion of the guide rail 5, the rope 7 that suspends the car 2 and the counterweight 3, and the rope 7 slides A suspension pulley 8 that can be freely wound, a support body 9 that rotatably supports the suspension pulley 8, and lower ends of the support body 9 are connected to the left and right portions of the support body 9, and inserted into the support beam 6. A suspension rod 10, a nut 11 that is screwed to the suspension rod 10 and fixes the suspension rod 10 on the upper portion of the support beam 6, and is inserted through the suspension rod 10 and arranged so as to contact the upper surface of the support beam 6. First plate 2, the elastic body 13 inserted through the suspension rod 10 and disposed so as to contact the upper surface of the first plate 12, and the first elastic body 13 inserted between the suspension rod 10 and disposed between the elastic body 13 and the nut 11. 2, a lock nut 15 that is screwed onto the suspension rod 10 and is in contact with the upper surface of the nut 11, and a split pin 16 that is attached to the upper end of the suspension rod 10.

このように構成される既設のエレベータ装置にあって、昇降体２、３の昇降移動に応じ、振動が吊りロッド１０から支持梁６に、次いで、支持梁６から昇降路壁１ａに伝わり、さらなる振動の低減が望まれる場合がある。   In the existing elevator apparatus configured as described above, the vibration is transmitted from the suspension rod 10 to the support beam 6 and then from the support beam 6 to the hoistway wall 1a in accordance with the elevating movement of the elevating bodies 2 and 3. Further, Reduction of vibration may be desired.

そこで、本実施形態にあっては、図５及び図６に示すように、吊りロッド１０に挿通され、第２のプレート１４の上面に接するように配置されるスペーサ２０と、吊りロッド１０に挿通され、スペーサ２０の上面に接するように配置される追設弾性体２１と、吊りロッド１０に挿通され、追設弾性体２１の上面に接するように配置される追設プレート２２と、吊りロッド１０に螺合され、追設プレート２２の上面に接するように配置される追設ナット２３とを備えている。   Therefore, in the present embodiment, as shown in FIGS. 5 and 6, the spacer 20 is inserted through the suspension rod 10 and is in contact with the upper surface of the second plate 14, and the suspension rod 10 is inserted. The additional elastic body 21 disposed so as to contact the upper surface of the spacer 20, the additional plate 22 inserted through the suspension rod 10 and disposed so as to contact the upper surface of the additional elastic body 21, and the suspension rod 10 And an additional nut 23 disposed so as to be in contact with the upper surface of the additional plate 22.

また、スペーサ２０は図７、図８及び図９に示すように、下面にナット１１の外形寸法よりも大きな寸法、即ち、ナット１１の幅寸法より大きな口径、及び、ナット１１の高さ寸法より大きな奥行き寸法を有する穴２０ａが形成されるとともに、その外径は第２のプレート１４の外径より小さなものに設定されている。   Further, as shown in FIGS. 7, 8, and 9, the spacer 20 has a lower dimension than the outer dimension of the nut 11, that is, a diameter larger than the width dimension of the nut 11 and a height dimension of the nut 11. A hole 20 a having a large depth dimension is formed, and the outer diameter thereof is set to be smaller than the outer diameter of the second plate 14.

次に、本実施形態の吊りロッド防振装置の取付け方法の作業手順を説明する。   Next, the work procedure of the attachment method of the suspension rod vibration isolator of this embodiment is demonstrated.

まず、割りピン１６を吊りロッド１０から取外すとともに、ロックナット１５を吊りロッド１０から取外して図４に示す状態とする。次に、図５に示すように、スペーサ２０を吊りロッド１０上端から挿入し、このスペーサ２０の下面に形成された穴２０ａに既設のナット１１を収納する。この状態で追設弾性体２１、次いで追設プレート２２を吊りロッド１０に挿通するとともに、追設ナット２３を螺合する。そして、追設ナット２３を既設の弾性体１３及び追設弾性体２１のそれぞれのたわみ量が規定値ｈとなるまで螺進させる。このとき作業員は両弾性体１３、２１のたわみ量が共に規定値ｈとなることを確認するとともに、支持梁６と吊り滑車８との隙間δ、及び、第１のプレート１２と吊りロッド１０の上端までの距離Ｌが、それぞれ図６に示すようにδ−ｎ、Ｌ＋ｎになっていることを確認する。これはナット１１がスペーサ２０の穴２０ａ内で第１のプレート１２から離隔し、追設ナット２３で荷重を受け、既設の弾性体１３及び追設弾性体２１のそれぞれにより振動が吸収されるようになったことを確認するためである。この後、図６に示すように、追設ナット２３の回り止めとしてロックナット１５を吊りロッド１０に螺合し、次いで、割りピン１６を取付けて作業を終了する。   First, the split pin 16 is removed from the suspension rod 10, and the lock nut 15 is removed from the suspension rod 10 to obtain the state shown in FIG. Next, as shown in FIG. 5, the spacer 20 is inserted from the upper end of the suspension rod 10, and the existing nut 11 is stored in the hole 20 a formed on the lower surface of the spacer 20. In this state, the additional elastic body 21 and then the additional plate 22 are inserted into the suspension rod 10 and the additional nut 23 is screwed. Then, the additional nut 23 is screwed until the deflection amount of each of the existing elastic body 13 and the additional elastic body 21 reaches a specified value h. At this time, the worker confirms that the amount of deflection of both elastic bodies 13 and 21 is the specified value h, and also the gap δ between the support beam 6 and the suspension pulley 8 and the first plate 12 and the suspension rod 10. It is confirmed that the distance L to the upper end of δ is δ−n and L + n as shown in FIG. This is because the nut 11 is separated from the first plate 12 in the hole 20 a of the spacer 20, receives a load by the additional nut 23, and the vibration is absorbed by each of the existing elastic body 13 and the additional elastic body 21. It is for confirming that it became. Thereafter, as shown in FIG. 6, the lock nut 15 is screwed onto the suspension rod 10 as a rotation stop for the additional nut 23, and then the split pin 16 is attached to complete the operation.

本実施形態によれば、追設弾性体２１を取付けるという簡易な構造で、建築物へ振動が伝達することを防止し、快適性の向上を図ることができるとともに、追設弾性体２１は、既設のナット１１を外すことなく、即ち、吊りロッド１０に荷重をかけたまま取付けることができることから、作業に要する労力及び時間を大幅に低減することができる。   According to the present embodiment, it is possible to prevent the vibration from being transmitted to the building with a simple structure of attaching the additional elastic body 21 and to improve the comfort. Since the existing nut 11 is not removed, that is, the suspension rod 10 can be attached while being loaded, labor and time required for the work can be greatly reduced.
