図１に示す本実施形態の移動手摺り劣化診断装置Ａは、移動手摺り１５に放射線すなわちＸ線を照射する放射線照射部であるＸ線源１と、移動手摺り１５を透過したＸ線を受光する放射線受光部２９とを備えている。放射線受光部２９は、例えばシンチレーター２とカメラ３により構成されており、Ｘ線を受けて発光したシンチレーター２を鏡を用いてカメラ３で撮影する構成となっている。 The moving handrail deterioration diagnosis apparatus A of the present embodiment shown in FIG. 1 uses an X-ray source 1 that is a radiation irradiating unit that irradiates the moving handrail 15 with radiation, that is, X-rays, and X-rays transmitted through the moving handrail 15. And a radiation receiving unit 29 for receiving light. The radiation receiving unit 29 includes, for example, a scintillator 2 and a camera 3, and has a configuration in which the scintillator 2 that emits light upon receiving X-rays is photographed by the camera 3 using a mirror.
また、本実施形態の移動手摺り劣化診断装置Ａは、Ｘ線源１を間隔変更部１０及び高さ変更部６を介してスライドレール付き支柱５に接続している。スライドレール付き支柱５の下方には支持台３０が接続され、支持台３０の下面側には複数のストッパー付キャスタ１２が設けられている。また、支持台３０の上面側にはＸ線源１から照射されるＸ線の発生を制御するＸ線制御装置１１が載置されている。 Moreover, the moving handrail deterioration diagnostic apparatus A of this embodiment connects the X-ray source 1 to the column 5 with a slide rail via the interval changing unit 10 and the height changing unit 6. A support base 30 is connected below the column 5 with slide rails, and a plurality of casters 12 with stoppers are provided on the lower surface side of the support base 30. An X-ray control device 11 that controls generation of X-rays emitted from the X-ray source 1 is placed on the upper surface side of the support base 30.
上述した間隔変更部１０は、Ｘ線源１を支持する支持部１０ａと、放射線受光部２９と接続され、支持部１０ａに設けられた挿通穴に挿通された支持支柱１０ｂと、支持部１０ａと支持支柱１０ｂとを固定する固定ネジ１０ｃとを含んでいる。したがって、固定ネジ１０ｃを緩めることにより支持支柱１０ｂが支持部１０ａの挿通穴に対して相対的に移動し、Ｘ線源１と放射線受光部２９との間隔を所望の間隔に設定できる。 The interval changing unit 10 described above is connected to the support unit 10a that supports the X-ray source 1, the radiation receiving unit 29, the support column 10b that is inserted through the insertion hole provided in the support unit 10a, and the support unit 10a. It includes a fixing screw 10c for fixing the support column 10b. Accordingly, by loosening the fixing screw 10c, the support column 10b moves relative to the insertion hole of the support portion 10a, and the interval between the X-ray source 1 and the radiation receiving portion 29 can be set to a desired interval.
また、上述した高さ変更部６は、ハンドル６ａを操作することによりスライドレール付き支柱５のスライドレール上を摺動させることができる。この高さ変更部６の高さを変更することによって、Ｘ線源１及び放射線受光部２９の高さ位置を変更することができる。 Moreover, the height change part 6 mentioned above can be slid on the slide rail of the support | pillar 5 with a slide rail by operating the handle 6a. By changing the height of the height changing unit 6, the height positions of the X-ray source 1 and the radiation receiving unit 29 can be changed.
さらに、高さ変更部６と間隔変更部１０は、角度変更部３１を介して接続されている。角度変更部３１は、Ｘ線源１及び放射線受光部２９の垂直方向の変更、すなわち図１の矢印で示すように仰角を変更させる垂直回転軸７と、この垂直回転軸７の回転を固定して、回転角を固定する垂直回転軸固定ネジ８を備えている。また、角度変更部３１は、Ｘ線源１及び放射線受光部２９を水平方向、すなわち図２に示す矢印の方向に回転させる水平回転軸１７と、この水平回転軸１７の回転を固定して、回転角を固定する水平回転軸固定ネジ９（図１に図示）を備えている。 Further, the height changing unit 6 and the interval changing unit 10 are connected via an angle changing unit 31. The angle changing unit 31 fixes the vertical rotation of the X-ray source 1 and the radiation receiving unit 29, that is, the vertical rotation shaft 7 that changes the elevation angle as indicated by the arrow in FIG. 1 and the rotation of the vertical rotation shaft 7. And a vertical rotation shaft fixing screw 8 for fixing the rotation angle. The angle changing unit 31 fixes the horizontal rotation shaft 17 that rotates the X-ray source 1 and the radiation receiving unit 29 in the horizontal direction, that is, the direction of the arrow shown in FIG. 2, and the rotation of the horizontal rotation shaft 17. A horizontal rotation shaft fixing screw 9 (shown in FIG. 1) for fixing the rotation angle is provided.
本実施形態にかかる劣化診断装置Ａを用いて移動手摺り１５の劣化診断を行う際には、映像データを蓄積し解析処理するパソコン１４を配置し、カメラ３とパソコン１４を映像を伝送する映像ケーブル１３によって接続するようにしている。 When performing deterioration diagnosis of the moving handrail 15 using the deterioration diagnosis apparatus A according to the present embodiment, a personal computer 14 for storing and analyzing video data is disposed, and a video for transmitting video between the camera 3 and the personal computer 14 is disposed. Connection is made by a cable 13.
このように構成された移動手摺り劣化診断装置Ａによって移動手摺り１５及びこの移動手摺り１５に埋設されたスチールコード１６を観察する際に、本実施形態を、図４に示す湾曲部１５ａ，１５ｂ，１５ｃ付近に設置することが行われる。以下、例えば湾曲部１５ａ付近に、本実施形態にかかる移動手摺り劣化診断装置Ａを設置して劣化診断する場合の手順について説明する。 When observing the moving handrail 15 and the steel cord 16 embedded in the moving handrail 15 by the moving handrail deterioration diagnosis device A configured as described above, the present embodiment is changed to the bending portion 15a, FIG. Installation in the vicinity of 15b and 15c is performed. Hereinafter, for example, a procedure in the case where the moving handrail deterioration diagnosis apparatus A according to the present embodiment is installed near the bending portion 15a to perform deterioration diagnosis will be described.
本実施形態で診断される移動手摺り１５は、湾曲部１５ａ，１５ｂを境にして上面側では、ステップ２６の移動方向と同じ方向に移動する。また、移動手摺り１５は、湾曲部１５ａ，１５ｂを境にして下面側では図示しないデッキベースの内部に引き入れられ、ステップ２６の移動方向と反対方向に移動する。 The moving handrail 15 diagnosed in the present embodiment moves in the same direction as the moving direction of step 26 on the upper surface side with the curved portions 15a and 15b as a boundary. Further, the moving handrail 15 is drawn into the inside of a deck base (not shown) on the lower surface side with the curved portions 15 a and 15 b as a boundary, and moves in the direction opposite to the moving direction of the step 26.
本実施形態の移動手摺り劣化診断装置Ａの設置のための準備作業として、まず、Ｘ線源１と放射線受光部２９のシンチレーター２の間に、移動手摺り１５の湾曲部１５ａが入るように、あらかじめＸ線源１と放射線受光部２９の間の距離や高さを、高さ変更部６及び間隔変更部１０を操作して調整する。 As a preparatory work for installing the moving handrail deterioration diagnosis apparatus A of the present embodiment, first, the curved portion 15 a of the moving handrail 15 is inserted between the X-ray source 1 and the scintillator 2 of the radiation receiving unit 29. The distance and height between the X-ray source 1 and the radiation receiving unit 29 are adjusted in advance by operating the height changing unit 6 and the interval changing unit 10.
移動手摺り１５の劣化診断をする際には、本実施形態の移動手摺り劣化診断装置Ａのキャスタ１２のストッパーを外し、移動手摺り１５の湾曲部１５ａの観察したい部位を観察できるようにこの劣化診断装置Ａの位置を決める。位置が決定したらキャスタ１２のストッパーで位置を固定する。さらに、高さ変更部６、間隔変更部１０、及び角度変更部３１等を操作して、観察したい部位に合わせて、Ｘ線源１と放射線受光部２９のシンチレーター２とが適正な位置となるように微調整を行う。この微調整により、Ｘ線源１からシンチレーター２に向かって照射されＸ線の方向は、図１に示した透写Ｘ線の方向４のようになる。 When diagnosing the deterioration of the moving handrail 15, the stopper of the caster 12 of the moving handrail deterioration diagnosing apparatus A of the present embodiment is removed so that the portion to be observed of the curved portion 15 a of the moving handrail 15 can be observed. The position of the deterioration diagnosis apparatus A is determined. When the position is determined, the position is fixed by the stopper of the caster 12. Furthermore, the X-ray source 1 and the scintillator 2 of the radiation receiving unit 29 are at appropriate positions by operating the height changing unit 6, the interval changing unit 10, the angle changing unit 31, and the like according to the site to be observed. Make fine adjustments. By this fine adjustment, the direction of X-rays irradiated from the X-ray source 1 toward the scintillator 2 becomes the transmitted X-ray direction 4 shown in FIG.
上述のようにＸ線源１と放射線受光部２９をセットした状態では、Ｘ線源１は移動手摺り１５の湾曲部１５ａの一方側に、放射線受光部２９はＸ線源１が配置されたのと同一面側の湾曲部１５ａの他方側に、湾曲部１５ａを間に挟んで配置されることになる。また、本実施形態の移動手摺り劣化診断装置Ａは、上述のように湾曲部１５ａをＸ線源１と放射線受光部２９の間に挟んだ状態で劣化診断を行う。なお、本実施形態の移動手摺り劣化診断装置Ａの操作に際しては、図２に示すように、鉛または鉛ゴムで作られた漏洩Ｘ線遮蔽部１８でＸ線源１及び放射線受光部２９を含む主要部の全体を覆うことが行われる。 In the state where the X-ray source 1 and the radiation receiving unit 29 are set as described above, the X-ray source 1 is arranged on one side of the curved portion 15a of the moving handrail 15 and the X-ray source 1 is arranged on the radiation receiving unit 29. The curved portion 15a is disposed on the other side of the curved portion 15a on the same plane as the above. Moreover, the moving handrail deterioration diagnosis apparatus A according to the present embodiment performs the deterioration diagnosis in a state where the bending portion 15a is sandwiched between the X-ray source 1 and the radiation receiving portion 29 as described above. In the operation of the moving handrail deterioration diagnosis apparatus A of the present embodiment, as shown in FIG. 2, the X-ray source 1 and the radiation light receiving unit 29 are connected by a leaky X-ray shielding unit 18 made of lead or lead rubber. Covering the entire main part including it is performed.
図３は本実施形態にかかる移動手摺り劣化診断装置Ａにより撮影された移動手摺りの透写画像を示す図である。 FIG. 3 is a view showing a transparent image of the moving handrail photographed by the moving handrail deterioration diagnosis apparatus A according to the present embodiment.
この図３に示すように、本実施形態の移動手摺り劣化診断装置Ａによって撮影された透写画像、すなわち透写したスチールコード１９や、このスチールコード１９の劣化によって生じた素線２１の透写画像がパソコン１４に写し出される。 As shown in FIG. 3, a transparent image photographed by the moving handrail deterioration diagnosis apparatus A of the present embodiment, that is, a transparent steel cord 19, and a transparent wire 21 caused by the deterioration of the steel cord 19 are transmitted. The copied image is displayed on the personal computer 14.
作業者は、パソコン１４に写し出された透写画像を確認しながら、透写Ｘ線の方向４が移動手摺り埋設スチールコード１６と重なる位置でＸ線源１と放射線受光部２９との間隔を変更する間隔変更部１０を調節する。このとき、Ｘ線源１及び放射線受光部２９の間隔は、できるだけ近づけるようにする。 While confirming the transmission image projected on the personal computer 14, the operator sets the interval between the X-ray source 1 and the radiation receiving unit 29 at a position where the direction 4 of the transmission X-ray overlaps the moving handrail embedded steel cord 16. The interval changing unit 10 to be changed is adjusted. At this time, the distance between the X-ray source 1 and the radiation receiving unit 29 is made as close as possible.
なお、移動手摺り埋設スチールコード１６は、素線と呼ばれる細い針金の数本が撚り合わされてストランドというやや太い針金となり、このストランドが数本さらに撚り合わされて構成されている。このように構成されるスチールコード１６を本実施形態の移動手摺り劣化診断装置Ａで透写したものが、図３に示されるスチールコード１９である。本実施形態では乗客コンベア２２の移動手摺り１５を、乗り場の折り返し先端部分の移動手摺り埋設スチールコード１６が曲がり山なりの状態となったところで透写する。透写したスチールコード１９が劣化している場合、ばらばらになった素線が、図３の素線２１のように写るので、判定箇所２０においてその様子が観察しやすい。 The moving handrail-embedded steel cord 16 is formed by twisting several thin wires called strands into a slightly thick wire called a strand, and twisting several strands. A steel cord 19 configured as described above is a steel cord 19 shown in FIG. In the present embodiment, the moving handrail 15 of the passenger conveyor 22 is copied when the moving handrail-embedded steel cord 16 at the front end portion of the landing is bent and mountain-like. When the steel cord 19 that has been seen through is deteriorated, the separated strands are copied like the strands 21 in FIG.
本実施形態は、移動手摺り１５に接触させずに撮影することができるため、乗客コンベア２２を稼働させながらＸ線動画を撮影することが可能である。さらに、判定箇所２０においてばらばらとなった素線が、図３の素線２１のように観察された場合には、Ｘ線源１及び放射線受光部２９の全体を垂直回転軸７を中心に垂直方向に回転させたり、水平回転軸１７を中心に水平方向に回転させて撮影することでその部位のみを詳細に検査することも可能である。すなわち、所望の位置で静止画を撮影することにより、さらに劣化状態を詳しく観察することができる。 In the present embodiment, since it is possible to take an image without contacting the moving handrail 15, it is possible to take an X-ray moving image while operating the passenger conveyor 22. Further, when the separated strands at the determination point 20 are observed as the strand 21 in FIG. 3, the entire X-ray source 1 and the radiation receiving unit 29 are vertically centered around the vertical rotation axis 7. It is also possible to inspect only the part in detail by rotating in the direction or rotating in the horizontal direction around the horizontal rotation shaft 17 and photographing. That is, by taking a still image at a desired position, the deterioration state can be further observed in detail.
本実施形態は、上述のようにＸ線源１と放射線受光部２９は、湾曲部１５ａにおけるスチールコード１６の頂部を照射可能に配置してある。湾曲部１５ａの頂部では、スチールコード１６が最外層に位置する。そのため、この位置を観察することで、スチールコード１６が他の部材と重なって透写されることが防止される。これにより診断精度を向上することが可能となる。 In the present embodiment, as described above, the X-ray source 1 and the radiation receiving unit 29 are arranged so as to be able to irradiate the top portion of the steel cord 16 in the bending portion 15a. At the top of the curved portion 15a, the steel cord 16 is positioned in the outermost layer. Therefore, by observing this position, it is possible to prevent the steel cord 16 from being overlapped with another member and being seen through. This makes it possible to improve diagnostic accuracy.
また、このような観点から、Ｘ線源１と放射線受光部２９を移動手摺り１５にセットする際には、湾曲部１５ａにおけるスチールコード１６の頂部を観察可能にセットするのが好ましい。 From this point of view, when setting the X-ray source 1 and the radiation receiving unit 29 on the moving handrail 15, it is preferable to set the top of the steel cord 16 in the bending portion 15a so as to be observable.
また、本実施形態の移動手摺り劣化診断装置Ａは、Ｘ線源１と放射線受光部２９の間隔を変更する間隔変更部１０を備え、湾曲部１５ａの形状に対応して間隔変更部１０によってＸ線源１と放射線受光部２９の間隔を調整可能なので、Ｘ線源１と放射線受光部２９との間隔は上述のようにできる限り近づけることにより、少ないＸ線出力で透写画像を得られるようにすることができる。これにより、診断時にＸ線が外部に漏えいするリスクを低減することができ、また、万一漏洩してしまっても外部への影響を大幅に低減できる。また、作業者の安全も確保しやすくなる。さらにこのような構成により、さまざまな形態の乗客コンベアに適用しやすくなる。 Moreover, the moving handrail deterioration diagnosis apparatus A of the present embodiment includes the interval changing unit 10 that changes the interval between the X-ray source 1 and the radiation receiving unit 29, and the interval changing unit 10 corresponds to the shape of the bending portion 15a. Since the interval between the X-ray source 1 and the radiation receiving unit 29 can be adjusted, a transmission image can be obtained with a small X-ray output by making the interval between the X-ray source 1 and the radiation receiving unit 29 as close as possible as described above. Can be. Thereby, the risk of X-rays leaking to the outside during diagnosis can be reduced, and even if they leak, the influence on the outside can be greatly reduced. Moreover, it becomes easy to ensure the safety of the operator. Furthermore, such a configuration facilitates application to various forms of passenger conveyors.
以上説明したように、本実施形態の移動手摺り劣化診断装置Ａは、乗客コンベア２２の移動手摺り１５の湾曲部分１５ａに沿ってＸ線を照射させるので、移動手摺り１５を取り外すことなく移動手摺り１５の透写、すなわち劣化診断を行うことができ、Ｘ線源１及び放射線受光部２９を含む当該劣化診断装置Ａの設置が簡単となる。さらに、Ｘ線源１と放射線受光部２９との間隔を、劣化診断可能に設置した状態で最少となるように配置状態を調整することができるので、Ｘ線出力を少なくすることができ、漏洩Ｘ線量を抑えることが可能となる。 As described above, the moving handrail deterioration diagnosis device A according to the present embodiment irradiates the X-ray along the curved portion 15a of the moving handrail 15 of the passenger conveyor 22, and thus moves without removing the moving handrail 15. The transmission of the handrail 15, that is, deterioration diagnosis can be performed, and the installation of the deterioration diagnosis apparatus A including the X-ray source 1 and the radiation light receiving unit 29 is simplified. Furthermore, since the arrangement state can be adjusted so that the interval between the X-ray source 1 and the radiation light receiving unit 29 is minimized in the state where the deterioration diagnosis is possible, the X-ray output can be reduced and leakage It becomes possible to suppress the X-ray dose.
また、本実施形態の移動手摺り劣化診断装置Ａは、Ｘ線による透写時には移動手摺り１５に埋設していたスチールコード１６を曲げた状態で透写するので、スチールコード１６が劣化してばらばらとなり素線となったものを的確に観察することができる。 In addition, the moving handrail deterioration diagnosis apparatus A according to the present embodiment transmits the steel cord 16 embedded in the moving handrail 15 in a bent state during the X-ray transmission, so that the steel cord 16 deteriorates. It is possible to observe exactly what has been broken and becomes a strand.
