Description

本発明は、エスカレーターや移動歩道等の乗客コンベアに備えられている移動手摺りの損傷を診断する技術に係り、特に移動手摺りの内部劣化を診断するための装置に関する。   The present invention relates to a technique for diagnosing damage to a moving handrail provided on a passenger conveyor such as an escalator or a moving sidewalk, and more particularly to an apparatus for diagnosing internal deterioration of a moving handrail.

従来、エスカレーターや移動歩道などの乗客コンベア用の移動手摺り内に埋設されているスチールコードの損傷の有無やその損傷の程度を診断するための装置（以降、移動手摺り劣化診断装置とする）として、移動手摺りに放射線を照射し、その透過画像をモニタ等に映し出す装置が用いられている。   Conventionally, a device for diagnosing the presence or degree of damage to steel cords embedded in moving handrails for passenger conveyors such as escalators and moving walkways (hereinafter referred to as moving handrail deterioration diagnosis device) For example, a device is used that irradiates a moving handrail with radiation and displays a transmitted image on a monitor or the like.

このような移動手摺り劣化診断装置として、放射線を照射する放射線発生部及び透過画像を映し出す蛍光部が、夫々移動手摺りの上方及び下方に位置するように欄干部を利用して固定される装置が提案されている（例えば、特許文献１参照）。特許文献１に開示されている移動手摺り劣化診断装置は、移動手摺りの進行方向から見て放射線発生部と蛍光部とが鉛直方向に対して斜めに配置される。これにより、乗客コンベアから移動手摺りを外すことなく、移動手摺りの放射線による内部劣化診断が可能となる。   As such a moving handrail deterioration diagnosis apparatus, an apparatus in which a radiation generating part for irradiating radiation and a fluorescent part for displaying a transmission image are fixed using a balustrade part so as to be located above and below the moving handrail, respectively. Has been proposed (see, for example, Patent Document 1). In the moving handrail degradation diagnosis device disclosed in Patent Document 1, the radiation generating unit and the fluorescent unit are arranged obliquely with respect to the vertical direction when viewed from the traveling direction of the moving handrail. Thereby, the internal deterioration diagnosis by the radiation of a moving handrail becomes possible, without removing a moving handrail from a passenger conveyor.

特開２００３−４８６８３号公報JP 2003-48683 A

しかしながら、特許文献１に記載の移動手摺り劣化診断装置では、放射線発生部と蛍光部の取り付けが難しいという問題があった。すなわち、移動手摺りの断面方向からみて放射線発生部と蛍光部が斜めになるため、位置決めが難しく、且つ両者の取り付け部構造が移動手摺りを跨ぐような構造となっているため、取り付け作業が困難であった。また、放射線発生部と蛍光部とが分割されており、機構的に隙間なく設置する構造ではないため、放射線の漏洩防止が困難であるという問題もあった。   However, the moving handrail deterioration diagnosis device described in Patent Document 1 has a problem that it is difficult to attach the radiation generating unit and the fluorescent unit. In other words, since the radiation generating part and the fluorescent part are oblique when viewed from the cross-sectional direction of the moving handrail, positioning is difficult, and the attachment part structure of the both straddles the moving handrail. It was difficult. In addition, since the radiation generating part and the fluorescent part are divided and are not mechanically installed without a gap, there is a problem that it is difficult to prevent radiation leakage.

本発明は上記不都合を鑑みてなされたもので、その目的はその取り付け作業が容易で、且つ放射線の漏洩防止をも良好に行うことが可能な乗客コンベアの移動手摺り劣化診断装置を提供することにある。   The present invention has been made in view of the above inconveniences, and an object of the present invention is to provide a moving handrail deterioration diagnosis device for a passenger conveyor that can be easily attached and can also prevent radiation leakage. It is in.

本発明の一態様は、乗客コンベアの移動手摺りの内部劣化を放射線により診断する劣化診断装置であって、前記移動手摺りに対して放射線を照射する光源を内部に含み、前記光源及び前記移動手摺りのうち前記光源によって照射される部分を覆う筐体によって構成される放射線発生部と、前記光源から照射された前記放射線により移動手摺りを透過した透過光を受光することにより前記移動手摺りを撮影する撮像部を内部に含み、前記撮像部及び前記移動手摺りのうち前記撮像部によって撮像される部分を覆う筐体によって構成され且つ前記放射線発生部の筐体と組み合わせられることにより前記光源、前記移動手摺り及び前記撮像部を覆う箱体となる受光部と、前記箱体を前記移動手摺りが貫通するための貫通穴において前記光源から照射される放射線が前記箱体の外部に漏れることを抑えるための遮蔽板とを含むことを特徴とする。   One aspect of the present invention is a deterioration diagnosis apparatus for diagnosing internal deterioration of a moving handrail of a passenger conveyor by radiation, and includes a light source that irradiates the moving handrail with radiation, the light source and the movement The moving handrail by receiving radiation transmitted through the moving handrail by the radiation irradiated from the light source and a radiation generating unit configured to cover a portion irradiated by the light source of the handrail The light source is configured by a housing that covers a portion of the imaging portion and the moving handrail that is imaged by the imaging portion, and is combined with the housing of the radiation generating portion. Irradiating from the light source in a light receiving unit that is a box that covers the moving handrail and the imaging unit, and a through hole through which the moving handrail passes through the box Radiation is characterized in that it comprises a shielding plate for suppressing leak outside of the box body.

ここで、前記放射線発生部及び前記受光部によって構成される箱体の前記移動手摺りの進行方向の幅は、前記乗客コンベアの踏み段の頂点間距離よりも短いことが好ましい。このように構成することで、該装置は、乗客コンベアの踏み段横の内部にある移動手摺りの返り側に容易に取り付けることができる。   Here, it is preferable that the width of the moving handrail in the traveling direction of the box constituted by the radiation generating unit and the light receiving unit is shorter than the distance between the vertices of the steps of the passenger conveyor. By comprising in this way, this apparatus can be easily attached to the return side of the moving handrail inside the step next to the passenger conveyor.

また、前記放射線発生部と前記受光部とを連結する連結部を更に含み、前記連結部は、前記光源から照射されて前記移動手摺りを透過した透過光が前記受光部によって受光されて前記移動手摺りが撮像されるような位置関係において前記前記放射線発生部と前記受光部とを連結することが好ましい。これにより、装置の設置時は放射線発生部と蛍光部の位置が必ず合うので両者の位置決めが簡単である。また位置合わせが完全なので放射線発生部と蛍光部の隙間がないため、放射線の漏洩が極めて少なくなる。   In addition, it further includes a connecting portion that connects the radiation generating portion and the light receiving portion, and the connecting portion receives the transmitted light that has been irradiated from the light source and transmitted through the moving handrail, and is received by the light receiving portion. It is preferable to connect the radiation generating unit and the light receiving unit in a positional relationship such that a handrail is imaged. As a result, when the apparatus is installed, the positions of the radiation generating part and the fluorescent part are always aligned, so that positioning of both is easy. Further, since the alignment is complete, there is no gap between the radiation generating part and the fluorescent part, so that radiation leakage is extremely reduced.

また、前記光源に電源を供給するための電源供給配線及び前記撮像部によって撮像された画像を外部に出力するための出力配線が、前記移動手摺りの進行方向において前記箱体から引き出されることが好ましい。これにより、配線類が乗客コンベアの踏み段に巻き込まれることなく布設することができる。   In addition, a power supply wiring for supplying power to the light source and an output wiring for outputting an image captured by the imaging unit to the outside may be drawn from the box in the traveling direction of the moving handrail. preferable. Thereby, wiring can be laid without being caught in the step of a passenger conveyor.

本発明により、その目的はその取り付け作業が容易で、且つ放射線の漏洩防止をも良好に行うことが可能な乗客コンベアの移動手摺り劣化診断装置を提供することができる。   According to the present invention, it is possible to provide a moving handrail deterioration diagnosis device for a passenger conveyor that can be easily attached and that can prevent radiation leakage well.

以下、本発明による乗客コンベアの移動手摺り診断装置について、図に基づいて説明する。図１は本実施形態に係る移動手摺り診断装置の構成を示す図である。また、図２は、本実施形態に係る移動手摺り診断装置を移動手摺り１０に取り付けた状態の外観を示す図である。図に示すように、本実施形態に係る移動手摺り診断装置は、移動手摺り１０の上方から被せられて配置される受光部１と、移動手摺り１０の下方から被せられて受光部１と対向するように配置される放射線発生部２とを備える。図２に示すように、受光部１と放射線発生部２とが移動手摺り１０を挟んで組み合わせられることにより箱状の形態となる。   DESCRIPTION OF THE PREFERRED EMBODIMENTS A passenger conveyor moving handrail diagnostic apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a moving handrail diagnosis apparatus according to the present embodiment. FIG. 2 is a diagram showing an external appearance of the mobile handrail diagnostic device according to the present embodiment attached to the mobile handrail 10. As shown in the figure, the moving handrail diagnostic device according to the present embodiment includes a light receiving unit 1 that is placed from above the moving handrail 10 and a light receiving unit 1 that is placed from below the moving handrail 10. And a radiation generator 2 arranged to face each other. As shown in FIG. 2, the light receiving unit 1 and the radiation generating unit 2 are combined with a moving handrail 10 in between to form a box shape.

受光部１は、取付部１ａと、透過画像を反射するための反射板１ｂと、反射板１ｂからの映像を撮影するカメラ１ｃと、カメラ１ｃの出力ケーブル１ｄと、受光部１と放射戦発生部２を連結するための連結部１ｅとを備えて構成されている。図１、２に示すように、受光部１は、少なくとも撮像部であるカメラ１ｃと、移動手摺り１０のうちカメラ１ｃによって撮像される部分を覆う筐体によって構成されている。   The light receiving unit 1 includes a mounting unit 1a, a reflecting plate 1b for reflecting a transmitted image, a camera 1c for capturing an image from the reflecting plate 1b, an output cable 1d of the camera 1c, a light receiving unit 1, and a radiation war. And a connecting portion 1e for connecting the portions 2 to each other. As illustrated in FIGS. 1 and 2, the light receiving unit 1 includes at least a camera 1 c that is an imaging unit and a housing that covers a portion of the moving handrail 10 that is imaged by the camera 1 c.

本実施形態に係る放射線発生部２はＸ線発生源である。この放射線発生部２は、Ｘ線発生器２ａと、Ｘ線発生器２ａの内部にあるＸ線発生管２ｂと、Ｘ線発生器２ａの電源を供給するための電源ケーブル２ｃと、受光部１と放射線発生部２を連結するための連結部２ｄと、放射線漏れを抑えるための遮蔽板２ｅとを備えて構成されている。図１、２に示すように、放射線発生部２は、少なくとも光源であるＸ線発生器２ａと、移動手摺り１０のうちＸ線発生器２ａによって照射される部分を覆う筐体によって構成されている。   The radiation generation unit 2 according to the present embodiment is an X-ray generation source. The radiation generator 2 includes an X-ray generator 2a, an X-ray generator tube 2b inside the X-ray generator 2a, a power cable 2c for supplying power to the X-ray generator 2a, and a light receiver 1 2d for connecting the radiation generating part 2 and a shielding plate 2e for suppressing radiation leakage. As shown in FIGS. 1 and 2, the radiation generation unit 2 is configured by at least an X-ray generator 2 a that is a light source and a casing that covers a portion of the moving handrail 10 that is irradiated by the X-ray generator 2 a. Yes.

そして、受光部１の筐体と放射線発生部２の筐体とが組み合わせられることにより、箱体が構成される。この箱体によって、移動手摺り１０のうちＸ線が照射されてカメラ１ｃによって撮像される部分、Ｘ線発生器２ａ及びカメラ１ｃが覆われる。即ち、放射線の経路が箱体によって覆われることとなり、放射線が外部に漏れることを防ぐことができる。   And the box is comprised by combining the housing | casing of the light-receiving part 1 and the housing | casing of the radiation generation part 2. FIG. The box body covers the portion of the moving handrail 10 that is irradiated with X-rays and imaged by the camera 1c, the X-ray generator 2a, and the camera 1c. That is, the path of the radiation is covered with the box, and the radiation can be prevented from leaking to the outside.

尚、本実施形態においては、遮蔽板２ｅが放射線発生部２の一部として設けられているが、これに限らない。遮蔽板２ｅは、図１に示すように、移動手摺り１０が上述した箱体を貫通するための貫通穴において、光源であるＸ線発生器２ａから照射される放射線が箱体の外部に漏れることを抑えるために設けられるものであり、受光部１側の一部であっても、受光部１及び放射線発生部２とは別に設けられても良い。   In the present embodiment, the shielding plate 2e is provided as a part of the radiation generating unit 2, but the present invention is not limited to this. As shown in FIG. 1, the shielding plate 2 e leaks radiation irradiated from the X-ray generator 2 a serving as a light source to the outside of the box in a through hole through which the moving handrail 10 penetrates the box described above. This is provided to suppress this, and may be provided separately from the light receiving unit 1 and the radiation generating unit 2 even in a part on the light receiving unit 1 side.

なお、カメラ１ｃの出力ケーブル１ｄには画像処理機３が連結されており、画像処理機３が、カメラ１ｃからの画像信号をディジタル信号に変換している。即ち、出力ケーブル１ｄは、カメラ１ｃによって撮像された画像を外部に出力するための出力配線である。画像処理機３によってディジタル化された画像信号は、画像処理機３から図示しないパーソナルコンピュータへ取り込まれて、移動手摺り１０の劣化診断に利用される。また電源４は、電源ケーブル２ｃを介してＸ線発生器２ａの電源を供給する構成である。即ち、電源ケーブル２ｃは、Ｘ線発生器２ａに電源を供給するための電源供給配線である。   Note that an image processor 3 is connected to the output cable 1d of the camera 1c, and the image processor 3 converts an image signal from the camera 1c into a digital signal. That is, the output cable 1d is an output wiring for outputting an image captured by the camera 1c to the outside. The image signal digitized by the image processor 3 is taken into the personal computer (not shown) from the image processor 3 and used for deterioration diagnosis of the moving handrail 10. The power supply 4 is configured to supply power to the X-ray generator 2a via the power cable 2c. That is, the power cable 2c is a power supply wiring for supplying power to the X-ray generator 2a.

ここで、図３は、一般的なエスカレーターの外観を示す図である。エスカレーターや動く歩道等を含む乗客コンベアの移動手摺り１０は、図３に示すように、欄干部１１上方を移動した後は必ず欄干部下方の躯体１２内部へ引き込まれ欄干部とは上下が逆となる返り側へ移動する構成である。そしてこの躯体１２内部においては、移動手摺り１０を押し出す機器以外の場所は比較的空間がある。   Here, FIG. 3 is a diagram showing the appearance of a general escalator. As shown in FIG. 3, the moving handrail 10 of the passenger conveyor including the escalator and the moving sidewalk is always drawn into the inside of the housing 12 below the balustrade part 11 and is upside down from the balustrade part. It moves to the return side. In the housing 12, there is a relatively space other than the device that pushes out the moving handrail 10.

本実施形態に係る移動手摺り劣化診断装置はこの躯体１２内部の空間を利用して設置するものである。移動手摺り劣化診断装置を取り付ける際、図２に示すように受光部１にある取付部１ａを、躯体１２内部にあるＬ字鋼材５に取り付ける。このとき受光部１全体の長さは、踏み段６の頂点間距離６ａよりも長いと装置が内部に入らないため、必ず頂点間距離よりも短くしなければならない。   The moving handrail deterioration diagnosis apparatus according to the present embodiment is installed using the space inside the housing 12. When attaching the moving handrail deterioration diagnosis device, as shown in FIG. 2, the attaching portion 1 a in the light receiving portion 1 is attached to the L-shaped steel material 5 inside the housing 12. At this time, if the length of the entire light receiving unit 1 is longer than the distance 6a between the vertices of the step 6, the apparatus cannot enter the interior, so it must be always shorter than the distance between the vertices.

また、躯体１２内部の空間に設置するという都合上、高さ方向にも制限がある。このため、図１に示すように、反射板１ｂを使い透過画像の方向を変えることで高さを高くすることなく、カメラ１ｃでの撮影を可能にしている。   Moreover, there is a restriction in the height direction because of the installation in the space inside the housing 12. For this reason, as shown in FIG. 1, it is possible to shoot with the camera 1c without increasing the height by changing the direction of the transmitted image using the reflector 1b.

受光部１を固定し終わった後、放射線発生部２を取り付ける。放射線発生部２は連結部１ｅと対になっている連結部２ｄを備えており、連結部１ｅと連結部２ｄは噛み合わせがうまくいかない限り固定できない構造となっている。これによって放射線発生部１と受光部２の位置がずれていて透過画像がうまく撮影できないという不具合を回避することができる。換言すると、連結部１ｅ及び連結２ｄは、光源であるＸ線発生器２ａから照射されて移動手摺り１０を透過した透過光が受光部であるカメラ１ｃによって受光され、これにより移動手摺り１０が撮像されるような位置関係においてのみ、受光部１と放射線発生部２とを連結する。   After the light receiving unit 1 is fixed, the radiation generating unit 2 is attached. The radiation generating unit 2 includes a connecting part 2d that is paired with the connecting part 1e, and the connecting part 1e and the connecting part 2d have a structure that cannot be fixed unless the meshing is successful. As a result, it is possible to avoid a problem that the positions of the radiation generating unit 1 and the light receiving unit 2 are shifted and a transmission image cannot be captured well. In other words, in the connecting portion 1e and the connecting 2d, the transmitted light that has been irradiated from the X-ray generator 2a that is a light source and transmitted through the moving handrail 10 is received by the camera 1c that is the light receiving portion. The light receiving unit 1 and the radiation generating unit 2 are connected only in such a positional relationship as to be imaged.

また、放射線発生部２と受光部１は隙間なく装着できるため、放射線の漏れを抑えることが可能である。さらに放射線発生部２には移動手摺りの進行方向への放射線の漏れを防止するための防止機構である遮蔽板２ｅを備えているため、装置からの放射線漏れ量は実測値で１．４μＳＶ／ｈと非常に低く抑えることができる。   Moreover, since the radiation generation part 2 and the light-receiving part 1 can be mounted without a gap, it is possible to suppress radiation leakage. Furthermore, since the radiation generator 2 is provided with a shielding plate 2e that is a prevention mechanism for preventing radiation leakage in the traveling direction of the moving handrail, the amount of radiation leakage from the apparatus is 1.4 μSV / actually measured. h and can be kept very low.

さらに出力ケーブル１ｄ、電源ケーブル２ｃは、移動手摺りの進行方向に出しているため、隣接する踏み段６に巻き込まれることなく布設可能である。   Furthermore, since the output cable 1d and the power cable 2c are extended in the traveling direction of the moving handrail, they can be laid without being caught in the adjacent step 6.

これによって乗客コンベアを通常運転で動かして移動手摺りの透過画像を撮影、診断することが可能になり、診断作業時間の大幅な短縮が実現できる。本発明による装置の取り付け時間は１０分程度であり、さらに放射線漏れ量は法規で規定されている２．５μＳＶ／ｈに対し、実測値１．４μＳＶ／ｈと約５０％低い。また、装置において一番放射線が漏れる部分は作業者が居ない部分であるため、周囲への安全性もより高いという効果がある。   As a result, the passenger conveyor can be moved in a normal operation, and a transmission image of the moving handrail can be taken and diagnosed, and the diagnostic work time can be greatly reduced. The installation time of the apparatus according to the present invention is about 10 minutes, and the radiation leakage amount is about 50% lower than the measured value of 1.4 μSV / h, compared to 2.5 μSV / h stipulated by the law. In addition, since the portion where the radiation leaks most in the device is a portion where there is no worker, there is an effect that the safety to the surroundings is higher.
