The sprocket 19 transmits rotation to each of the plurality of rollers 20. Each of the pair of handrails 9 receives pressure from each of the plurality of rollers 21 in contact with each other, and circulates and moves by the frictional force between the plurality of rollers 20 in contact with each other. Each of the pair of handrails 9 circulates at the same moving speed as each of the plurality of steps 8.
　エスカレーターである乗客コンベア１の上り運転時に、利用者は、一対の手摺９の一方をつかんで第２乗降口２ｂから複数のステップ８のいずれかに乗る。利用者は、往路を移動するステップ８に乗って第１乗降口２ａに移動する。 When the passenger conveyor 1 which is an escalator is going up, the user grabs one of the pair of handrails 9 and gets on one of the plurality of steps 8 from the second entrance 2b.

The detector 32 supports the stylus 30 so as to be movable in the longitudinal direction.
　例えば、乗客コンベア１のチェーンＡの点検時において、設置工程と回転移動工程と検出工程と記憶工程と算出工程とが行われる。 For example, when inspecting the chain A of the passenger conveyor 1, the installation process, the rotational movement process, the detection process, the storage process, and the calculation process are performed.
　設置工程において、作業員は、チェーンＡがスプロケットＢに噛み合い始める位置または噛み合い終わる位置において隣接した２つの連結体Ｃに滑らかに２点で線接触する位置に点検治具２２の接触子３１を配置させる。図示されないが、この状態において、作業員は、スプロケットＢを支持するベアリングユニット等に検出器３２を固定する。 In the installation process, the worker arranges the contactor 31 of the inspection jig 22 at a position where the chain A starts to mesh with the sprocket B or at a position where the chain A smoothly makes line contact with two adjacent connecting bodies C at two points. Let me. Although not shown, in this state, the worker fixes the detector 32 to a bearing unit or the like that supports the sprocket B.
　この際、測定子３０は、基準とするチェーンＡが回転移動する際に接触している２つの連結体Ｃの振れ量に応じてスプロケットＢの回転軸に対して離れる方向と近づく方向と変位する位置に配置される。測定子３０は、リンクＤに接触しない位置に配置される。 At this time, the stylus 30 is displaced in a direction away from the rotation axis of the sprocket B and in a direction approaching the rotation axis of the sprocket B according to the amount of deflection of the two connecting bodies C in contact with each other when the reference chain A rotates. Placed in position. The stylus 30 is arranged at a position where it does not come into contact with the link D.
　その後、回転移動工程において、作業員は、制御盤の設定を変更することでチェーンＡを少なくとも一周は回転移動させる。例えば、作業員は、制御盤の設定を変更することでチェーンＡの一方向および多方向の両方について少なくとも一周は回転させる。 After that, in the rotary movement process, the worker rotates and moves the chain A at least once by changing the setting of the control panel. For example, the worker rotates the chain A at least once in both one-way and multi-directions by changing the setting of the control panel.
　この際、検出工程において、検出器３２は、チェーンＡが回転移動している際の接触子３１の変位量を検出する。 At this time, in the detection step, the detector 32 detects the displacement amount of the contactor 31 when the chain A is rotating and moving.
　この際、記憶工程において、検出器３２は、ピークまたはピークｔｏピークのホールドの機能を用いて接触子３１の変位量の最大値の情報を記憶する。 At this time, in the storage step, the detector 32 stores the information of the maximum value of the displacement amount of the contactor 31 by using the peak or peak-to-peak hold function.
　その後、作業員は、記憶工程により記憶された変位量の最大値の情報に基づいてチェーンＡの伸び量の推定値を保守端末等の算出装置により算出する。 After that, the worker calculates the estimated value of the elongation amount of the chain A by a calculation device such as a maintenance terminal based on the information of the maximum value of the displacement amount stored in the storage process.
　次に、図５を用いて、点検治具２２による接触子３１の変位量の検出結果を説明する。
　図５は実施の形態１における乗客コンベアのチェーンの点検治具による接触子の変位量の検出結果を示す図である。 Next, the detection result of the displacement amount of the contactor 31 by the inspection jig 22 will be described with reference to FIG.
FIG. 5 is a diagram showing the detection result of the displacement amount of the contacts by the inspection jig of the chain of the passenger conveyor in the first embodiment.
　図５において、Ｅは、基準となる新品のチェーンにおいて乗客コンベアを上昇運転または下降運転した際の接触子３１の変位量である。Ｆは、伸びが発生しているチェーンにおいて乗客コンベアを下降運転した際の接触子３１の変位量である。この際、接触子３１の位置は、チェーンがスプロケットと噛み合い終わる位置に相当する。Ｇは、伸びが発生しているチェーンにおいて乗客コンベアを上昇運転した際の接触子３１の変位量である。この際、接触子３１の位置は、チェーンがスプロケットと噛み合い始める位置に相当する。 In FIG. 5, E is the displacement amount of the contactor 31 when the passenger conveyor is operated ascending or descending in a new reference chain. F is the displacement amount of the contactor 31 when the passenger conveyor is lowered in the chain in which the elongation is generated. At this time, the position of the contactor 31 corresponds to the position where the chain finishes meshing with the sprocket. G is the displacement amount of the contactor 31 when the passenger conveyor is operated ascending in the chain in which the elongation is generated. At this time, the position of the contactor 31 corresponds to the position where the chain starts to mesh with the sprocket.
　Ｅに示されるように、新品のチェーンにおいても、接触子３１は、一定の量だけ変位する。Ｆに示されるように、チェーンがスプロケットと噛み合い終わる位置において、接触子３１の変位量は、チェーンのリンクの伸び率に応じて増加する。Ｇに示されるように、チェーンがスプロケットと噛み合い始める位置において、接触子３１の変位量は、チェーンのリンクの伸び率に応じて増加する。 As shown in E, even in a new chain, the contactor 31 is displaced by a certain amount. As shown in F, at the position where the chain finishes meshing with the sprocket, the displacement amount of the contactor 31 increases according to the elongation rate of the link of the chain. As shown by G, at the position where the chain begins to mesh with the sprocket, the amount of displacement of the contact 31 increases according to the elongation rate of the link of the chain.
　チェーンのリンクの伸び率に対し、Ｃの変位量の増加率は、Ｂの変化量の増加率よりも高い。この場合、チェーンがスプロケットと噛み合い始める位置において接触子３１の変位量を検出することで、チェーンの一部分の伸びが少量である場合でも当該伸びがより確実に把握される。 The rate of increase in the amount of displacement of C is higher than the rate of increase in the amount of change in B with respect to the rate of increase in the chain link. In this case, by detecting the displacement amount of the contactor 31 at the position where the chain starts to mesh with the sprocket, the elongation can be more reliably grasped even if the elongation of a part of the chain is small.
　以上で説明した実施の形態１によれば、接触子３１は、チェーンが回転移動する際に接触している２つの連結体の振れ量に応じてスプロケットの回転軸に対して離れる方向または近づく方向に変位する。このため、チェーンのリンクの一部分のみが伸びている場合でも、当該伸びを正確に把握することができる。 According to the first embodiment described above, the contactor 31 is in a direction away from or closer to the rotation axis of the sprocket depending on the amount of deflection of the two connecting bodies in contact with each other when the chain is rotationally moved. Displace to. Therefore, even if only a part of the link of the chain is extended, the extension can be accurately grasped.
　また、検出器３２は、チェーンが一周した際の接触子３１の振れ量の最大値の情報を記憶する。このため、チェーンの伸びをより正確に把握することができる。 Further, the detector 32 stores information on the maximum value of the amount of runout of the contactor 31 when the chain goes around. Therefore, the elongation of the chain can be grasped more accurately.
　また、接触子３１は、基準とするチェーンが回転移動する際に接触している２つの連結体の振れ量に応じて前記スプロケットの回転軸に対して離れる方向と近づく方向と変位する位置に配置される。このため、チェーンの伸びをより容易に把握することができる。 Further, the contactor 31 is arranged at a position where the contactor 31 is displaced from the rotation axis of the sprocket in a direction away from or closer to the rotation axis of the sprocket according to the amount of runout of the two connecting bodies in contact with each other when the reference chain rotates. Will be done. Therefore, the elongation of the chain can be grasped more easily.
　また、接触子３１は、リンクに接触しない位置に配置される。このため、接触子３１の変位量をより正確に検出することができる。その結果、チェーンの伸びをより正確に把握することができる。 Further, the contactor 31 is arranged at a position where it does not come into contact with the link. Therefore, the displacement amount of the contactor 31 can be detected more accurately. As a result, the elongation of the chain can be grasped more accurately.
　なお、実施の形態１の点検治具２２を動く歩道のチェーンに適用してもよい。この場合も、チェーンの伸びを正確に把握することができる。 The inspection jig 22 of the first embodiment may be applied to a moving walkway chain. In this case as well, the elongation of the chain can be accurately grasped.
　以上のように、この発明に係るエレベーターの点検治具および点検方法は、乗客コンベアに利用できる。 As described above, the elevator inspection jig and inspection method according to the present invention can be used for the passenger conveyor.
