本発明は、乗客コンベアに備えられ、ハンドレール駆動装置に含まれる従動ローラをハンドレールに押圧する従動ローラ押圧装置を、脱着させる際に用いられる従動ローラ押圧装置の脱着サポート治具に関する。 The present invention relates to an attachment / detachment support jig for a driven roller pressing device that is provided in a passenger conveyor and is used when a driven roller pressing device that presses a driven roller included in a handrail driving device against the handrail is attached / detached.
乗客コンベア例えばエスカレータには、ハンドレールを駆動させるハンドレール駆動装置が備えられている。このハンドレール駆動装置は、ハンドレール駆動チェーンを介して駆動する駆動ローラと、従動ローラと、この従動ローラをばね力を介してハンドレールに押圧する従動ローラ押圧装置とを含んでいる。ハンドレールは、駆動ローラと従動ローラとによって挟まれるように配置されて循環移動する。 Passenger conveyors, such as escalators, are provided with a handrail drive device that drives the handrail. The handrail driving device includes a driving roller that is driven via a handrail driving chain, a driven roller, and a driven roller pressing device that presses the driven roller against the handrail via a spring force. The handrail is arranged so as to be sandwiched between the driving roller and the driven roller and circulates and moves.
従動ローラの材質はゴムであることから、経年劣化や磨耗による径減少に伴い、交換が必要になる。また、従動ローラ押圧装置が、従動ローラを保持し、回動可能なレバーを含むものにあっては、レバーの支軸と、この支軸を受ける軸受との固渋を防ぐために、これらの支軸と軸受との間に注油が必要になる。 Since the material of the driven roller is rubber, it needs to be replaced as the diameter decreases due to aging or wear. Further, in the case where the driven roller pressing device includes a lever that holds the driven roller and can be rotated, in order to prevent tightness between the support shaft of the lever and the bearing that receives this support shaft, Lubrication is required between the shaft and the bearing.
レバーを有する従動ローラ押圧装置にあって、交換や注油を行う際には、従来、従動ローラ押圧装置に含まれ、従動ローラをハンドレールに押圧するようにレバーを付勢するばねを押す押しボルトを緩めて、ばねと、このばねを受けるばね受を取り外してから、従動ローラを保持するレバーを取り外すようにしている。 In a driven roller pressing device having a lever, when performing replacement or lubrication, a push bolt that is conventionally included in the driven roller pressing device and presses a spring that urges the lever to press the driven roller against the handrail And the lever that holds the driven roller is removed after the spring and the spring receiver that receives the spring are removed.
なお、エスカレータのハンドレール駆動装置に備えられる従動ローラ押圧装置を脱着する技術が特許文献１に開示されている。この特許文献１に開示された技術は、本発明が対象としているような従動ローラを保持するレバー、このレバーを付勢するばね、及びばねを受けるばね受を備えた構成ではないが、ハンドレールを押圧するように従動ローラを付勢する板ばねを拘束する拘束治具を備えた構成となっている。従動ローラを取り外す際には、拘束治具によって板ばねを、ばね力の影響を及ぼさせないように拘束し、これによって従動ローラの簡単な取り外しを可能としたものである。 Patent Document 1 discloses a technique for detaching a driven roller pressing device provided in a handrail driving device for an escalator. The technique disclosed in Patent Document 1 is not a configuration including a lever that holds a driven roller, a spring that biases the lever, and a spring receiver that receives the spring as the subject of the present invention. It is the structure provided with the restraining jig | tool which restrains the leaf | plate spring which urges | biases a driven roller so that may be pressed. When the driven roller is removed, the leaf spring is restrained by a restraining jig so as not to exert the influence of the spring force, thereby enabling easy removal of the driven roller.
ところで従来、従動ローラ押圧装置が、従動ローラを保持するレバー、このレバーを付勢するばね、及びばねを受けるばね受を備えた構成のものでは、従動ローラを取り外す際に、ばね、あるいはばね受が誤ってトラスの内部に落下してしまうことがあった。このようなばね、あるいはばね受の落下を生じると、従動ローラの脱着作業が煩雑になり、作業能率が著しく低下してしまう。エスカレータの場合には傾斜部を有することから、傾斜部にばね、あるいはばね受が落下した場合には、作業がより煩雑になってしまう。 By the way, in the conventional structure in which the driven roller pressing device includes a lever that holds the driven roller, a spring that urges the lever, and a spring receiver that receives the spring, when the driven roller is removed, the spring or the spring receiver Accidentally dropped into the truss. If such a spring or a spring bearing is dropped, the work of detaching the driven roller becomes complicated, and the work efficiency is remarkably lowered. In the case of an escalator, since it has an inclined part, when a spring or a spring receiver falls on the inclined part, the work becomes more complicated.
なお、特許文献１には、従動ローラを保持するレバー、このレバーを付勢するばね、及びばねを受けるばね受については開示が無い。したがって、レバーを付勢するばね、及びばねを受けるばね受を備えた従動ローラ押圧装置の脱着時のばね、ばね受のトラスの内部への落下を防止する技術についても、何ら開示がなされていない。 Patent Document 1 does not disclose a lever that holds the driven roller, a spring that biases the lever, and a spring receiver that receives the spring. Accordingly, there is no disclosure of a spring for urging the lever, a spring when the driven roller pressing device including the spring receiver for receiving the spring is detached, and a technique for preventing the spring receiver from falling into the truss. .

Including both sides of the escalator 1, six drive rollers 11 and six driven rollers 12c are provided. According to the number of driven rollers 12c, six driven roller pressing devices 12 are provided as a whole.
従動ローラ押圧装置１２を、ベース１０に対して着脱させる際に用いられる本実施形態に係る脱着サポート治具１３は、図３に示すように、レバー１２ｂの上部、例えばレバー１２ｂの先端部１２ｂ１の上部に当接する第１当接部、例えば第１平坦部１３ａと、下部ばね受１２ｆの下部に当接可能な第２当接部、例えば第２平坦部１３ｂと、第１平坦部１３ａと第２平坦部１３ｂとを連設させる連設部、例えば上下方向に延設される立設部１３ｃとを含んでいる。第２平坦部１３ｂには、押しボルト１２ｅとの干渉を避ける切り欠き部１３ｄを形成してある。また、脱着サポート治具１３は、第１平坦部１３ａと、第２平坦部１３ｂと、立設部１３ｃとを含めて、側面視の全体形状をコ字形状に形成してある。 The attachment / detachment support jig 13 according to this embodiment used when the driven roller pressing device 12 is attached to and detached from the base 10 is, as shown in FIG. 3, an upper portion of the lever 12b, for example, the tip 12b1 of the lever 12b. A first contact portion that contacts the upper portion, for example, a first flat portion 13a, and a second contact portion that can contact the lower portion of the lower spring receiver 12f, for example, a second flat portion 13b, a first flat portion 13a, and a first flat portion 13a. 2 includes a continuous portion that is connected to the flat portion 13b, for example, a standing portion 13c that extends in the vertical direction. The second flat portion 13b is formed with a cutout portion 13d that avoids interference with the push bolt 12e. Moreover, the attachment / detachment support jig 13 includes a first flat portion 13a, a second flat portion 13b, and an upright portion 13c, and the entire shape in a side view is formed in a U shape.
次に、図４〜６に基づいて、前述のように構成した本実施形態に係る脱着サポート治具１３を用いて、従動ローラ押圧装置１２をトラス２の内部２ａに配置されるベース１０から取り外す動作を説明する。 Next, based on FIGS. 4 to 6, the driven roller pressing device 12 is removed from the base 10 disposed in the interior 2 a of the truss 2 using the attachment / detachment support jig 13 according to the present embodiment configured as described above. The operation will be described.
はじめに、図４に示すように、例えば脱着サポート治具１３の立設部１３ｃを把持して、第１平坦部１３ａがレバー１２ｂの先端部１２ｂ１上に当接するように、また、第２平坦部１３ｂの切り欠き部１３ｄ内に押しボルト１２ｅが収容されるようにして、すなわち押しボルト１２ｅを切り欠き部１３ｄ内において相対的に移動させるようにして、また、第２平坦部１３ｂが下部ばね受１２ｆの下方に位置するように、脱着サポート治具１３をベース１０側に向けて押し込む。 First, as shown in FIG. 4, for example, the first flat portion 13 a is held on the tip end portion 12 b 1 of the lever 12 b by holding the standing portion 13 c of the attachment / detachment support jig 13, and the second flat portion. The push bolt 12e is accommodated in the notch 13d of 13b, that is, the push bolt 12e is moved relatively in the notch 13d, and the second flat portion 13b is received by the lower spring support. The attachment / detachment support jig 13 is pushed toward the base 10 so as to be positioned below 12f.
この状態でロックナット１２ｇを緩め、押しボルト１２ｅを回転させ、押しボルト１２ｅを例えばブラケット１４ａのねじ穴１４ｂから離脱させる。これにより、押しボルト１２ｅとロックナット１２ｇがブラケット１４ａから取り出され、ばね１２ｄが例えばわずかに伸長し、下部ばね受１２ｆがばね１２ｄのばね力によって第２平坦部１３ｂに押圧される。したがって、ばね１２ｄと下部ばね受１２ｆは、レバー１２ｂの先端部１２ｂ１と脱着サポート治具１３の第２平坦部１３ｂとによって挟まれるようにして、レバー１２ｃと脱着サポート治具１３とに一体的に保持された状態となる。 In this state, the lock nut 12g is loosened, the push bolt 12e is rotated, and the push bolt 12e is detached from the screw hole 14b of the bracket 14a, for example. Thereby, the push bolt 12e and the lock nut 12g are taken out from the bracket 14a, the spring 12d is extended slightly, for example, and the lower spring receiver 12f is pressed against the second flat portion 13b by the spring force of the spring 12d. Therefore, the spring 12d and the lower spring support 12f are integrated with the lever 12c and the attachment / detachment support jig 13 so as to be sandwiched between the tip 12b1 of the lever 12b and the second flat portion 13b of the attachment / detachment support jig 13. It will be held.
次に、図５に示すように、レバー１２ｂの支軸１２ａを固定していた図示しないナットを緩めて、支軸１２ａを抜き取る。 Next, as shown in FIG. 5, a nut (not shown) that has fixed the support shaft 12a of the lever 12b is loosened to extract the support shaft 12a.
この状態で、図６に示すように、従動ローラ１２ｃを保持したレバー１２ｂと、脱着サポート治具１３と、ばね１２ｄと、下部ばね受１２ｆとを含む一体構造物を取り外す。これによって、従動ローラ１２ｃを新しい従動ローラ１２ｃに交換する作業が可能となる。また例えば、支軸１２ａの軸受１２ｈへの注油作業が可能となる。以上の動作は、ブラケット１４ａ側について説明したが、ブラケット１５ａ側についても同様の動作が行われる。 In this state, as shown in FIG. 6, the integrated structure including the lever 12b holding the driven roller 12c, the attachment / detachment support jig 13, the spring 12d, and the lower spring support 12f is removed. As a result, it is possible to replace the driven roller 12c with a new driven roller 12c. Further, for example, it is possible to lubricate the bearing 12h of the support shaft 12a. Although the above operation has been described on the bracket 14a side, the same operation is performed on the bracket 15a side.
また、新しい従動ローラ１２ｃが取り付けられたレバー１２ｂと、脱着サポート治具１３と、ばね１２ｄと、下部ばね受１２ｆとを含む一体構造物をベース１０に取り付ける動作は、前述の取り外し時の動作と逆の手順で行う。 The operation of attaching the integrated structure including the lever 12b to which the new driven roller 12c is attached, the attachment / detachment support jig 13, the spring 12d, and the lower spring receiver 12f to the base 10 is the same as the operation at the time of removal described above. Reverse the procedure.
すなわち、図６に示す一体構造物を、図５に示すように、ベース１０側の所定の箇所に配置し、レバー１２ｂの支軸１２ａを軸受１２ｈに挿入し、図示しないナットによって支軸１２ａを固定する。 That is, as shown in FIG. 5, the integral structure shown in FIG. 6 is arranged at a predetermined location on the base 10 side, the support shaft 12a of the lever 12b is inserted into the bearing 12h, and the support shaft 12a is attached by a nut (not shown). Fix it.
次に、ロックナット１２ｇを装着した状態の押しボルト１２ｅをブラケット１４ａのねじ穴１４ｂに螺合させ、脱着サポート治具１３の切り欠き部１３ｄから挿入し、下部ばね受１２ｆに当たるまで押し込む。ここで、押しボルト１２ｅの押し込み量を調整して、ばね１２ｄのばね力を所定の設定値に保つ。このようにばね１２ｄのばね力が所定の設定値となった状態で、ロックナット１２ｇをブラケット１４ａに当接するように締め付けて押しボルト１２ｅを固定する。これにより、従動ローラ１２ｃを含めた前述した一体構造物のベース１０への取り付けが終了する。 Next, the push bolt 12e with the lock nut 12g attached is screwed into the screw hole 14b of the bracket 14a, inserted through the notch 13d of the attachment / detachment support jig 13, and pushed in until it hits the lower spring support 12f. Here, the pushing amount of the push bolt 12e is adjusted to keep the spring force of the spring 12d at a predetermined set value. In this manner, in a state where the spring force of the spring 12d becomes a predetermined set value, the lock bolt 12e is fixed by tightening the lock nut 12g so as to contact the bracket 14a. Thereby, the attachment to the base 10 of the integrated structure mentioned above including the driven roller 12c is complete | finished.
以上のように構成した本実施形態によれば、従動ローラ１２ｃを保持するレバー１２ｂ、このレバー１２ｂを付勢するばね１２ｄ、このばね１２ｄを受ける下部ばね受１２ｆ、及び上部ばね受を形成するレバー１２ｂの先端部１２ｂ１を有する従動ローラ押圧装置１２の脱着作業に際し、ばね１２ｄ及び下部ばね受１２ｆを取り外すことなく脱着作業を行うことができる。すなわち本実施形態は、従動ローラ押圧装置１２の脱着作業に際し、ばね１２ｄ及び下部ばね受１２ｆのトラス２の内部２ａへの落下を防止することができる。これにより安定した、能率の良い従動ローラ押圧装置１２の脱着作業を実現させることができる。 According to the present embodiment configured as described above, the lever 12b that holds the driven roller 12c, the spring 12d that biases the lever 12b, the lower spring receiver 12f that receives the spring 12d, and the lever that forms the upper spring receiver When the driven roller pressing device 12 having the front end portion 12b1 of 12b is attached / detached, the attaching / detaching operation can be performed without removing the spring 12d and the lower spring receiver 12f. That is, this embodiment can prevent the spring 12d and the lower spring receiver 12f from dropping into the interior 2a of the truss 2 when the driven roller pressing device 12 is attached or detached. As a result, it is possible to realize a stable and efficient removal operation of the driven roller pressing device 12.
また、本実施形態は、従動ローラ１２ｃを保持したレバー１２ｂを取り外すために脱着サポート治具１３をベース１０側に挿入し、押しボルト１２ｅを緩めた際に、ばね１２ｄがわずかに伸長して、下部ばね受１２ｆが脱着サポート治具１３の第２平坦部１３ｂに当接する状態となる。このときのばね１２ｄの伸長変化量を小さく抑えることができる。したがって、新しい従動ローラ１２ｃを保持したレバー１２ｂ、脱着サポート治具１３、ばね１２ｄ、及び下部ばね受１２ｆを含む一体構造物を、ベース１０側に挿入し、押しボルト１２ｅを回転させて下部ばね受１２ｆを押し上げて行うばね１２ｄのばね力の調整作業は、前述したばね１２ｄの伸長変化量を略ゼロにする調整作業でよい。これにより本実施形態は、ばね１２ｄのばね力の調整作業を比較的容易に行うことができる。 Further, in this embodiment, when the attachment / detachment support jig 13 is inserted into the base 10 side to remove the lever 12b holding the driven roller 12c and the push bolt 12e is loosened, the spring 12d is slightly extended, The lower spring support 12 f comes into contact with the second flat portion 13 b of the attachment / detachment support jig 13. At this time, the amount of change in the extension of the spring 12d can be kept small. Therefore, an integrated structure including the lever 12b holding the new driven roller 12c, the attachment / detachment support jig 13, the spring 12d, and the lower spring receiver 12f is inserted into the base 10 side, and the lower bolt holder is rotated by rotating the push bolt 12e. The adjustment operation of the spring force of the spring 12d performed by pushing up 12f may be an adjustment operation for making the extension change amount of the spring 12d described above substantially zero. Thereby, this embodiment can perform adjustment work of spring force of spring 12d comparatively easily.
