　ここで、上記国際公開第２０１９／１７１６６７号には記載されていないが、ワイヤロープ検査装置では、ワイヤロープが振動して検知コイルに接触することを抑制するために、検知コイルとワイヤロープとの間の距離は、ワイヤロープの最大振動揺れ幅よりも大きくなるように構成されている。一方、検知コイルによって精度よくワイヤロープの検査を行うためには、検知コイルとワイヤロープとの間の距離は、可能な限り小さくする方が望ましい。すなわち、上記国際公開第２０１９／１７１６６７号に記載されているようなワイヤロープ検査装置では、検知コイルとワイヤロープとの間の距離は、ワイヤロープの最大振動揺れ幅よりも大きく、かつ、可能な限り小さくなるように構成されることが望ましい。 Here, although not described in the above-mentioned International Publication No. 2019/171667, in the wire rope inspection device, in order to prevent the wire rope from vibrating and coming into contact with the detection coil, the detection coil and the wire rope are used. The distance between them is configured to be greater than the maximum vibration swing width of the wire rope. On the other hand, in order to inspect the wire rope with high accuracy by the detection coil, it is desirable that the distance between the detection coil and the wire rope is as small as possible. That is, in the wire rope inspection device as described in International Publication No. 2019/171667, the distance between the detection coil and the wire rope is larger than the maximum vibration swing width of the wire rope and is possible. It is desirable that it be configured to be as small as possible.
　しかしながら、検査対象であるワイヤロープの外表面から飛び出した部分（素線切れに起因する素線の飛び出しなど）がある場合には、検知コイルに飛び出した部分が接触する可能性がある。そのため、検知コイルを近づけてワイヤロープの検査を精度よく行いながら、検査対象であるワイヤロープから飛び出した部分と検知コイルとの接触を抑制することが可能なワイヤロープ検査装置、および、ワイヤロープ検査システムが望まれている。 However, if there is a part protruding from the outer surface of the wire rope to be inspected (such as a part protruding from the wire due to a broken wire), the part protruding from the detection coil may come into contact. Therefore, a wire rope inspection device capable of suppressing contact between the portion protruding from the wire rope to be inspected and the detection coil while accurately inspecting the wire rope by bringing the detection coil close to the wire rope, and wire rope inspection. A system is desired.
　この発明は、上記のような課題を解決するためになされたものであり、この発明の１つの目的は、検知コイルを近づけてワイヤロープの検査を精度よく行いながら、検査対象であるワイヤロープから飛び出した部分と検知コイルとの接触を抑制することが可能なワイヤロープ検査装置、および、ワイヤロープ検査システムを提供することである。 The present invention has been made to solve the above-mentioned problems, and one object of the present invention is to inspect the wire rope accurately while bringing the detection coil close to the wire rope to be inspected. It is an object of the present invention to provide a wire rope inspection device capable of suppressing contact between a protruding portion and a detection coil, and a wire rope inspection system.

Based on the detection coil that detects the magnetic flux of the wire rope while moving relatively, the pop-out detection unit that detects the pop-out portion from at least a part of the outer surface of the wire rope, and the detection signal from the pop-out detection unit. It is provided with a drive unit for moving the detection coil in a direction away from the wire rope before the protruding portion comes into contact with the detection coil. In addition, in this specification, the "protruding portion" means a twisted, broken, kink, or kink of the wire rope, in addition to the portion where the wire broken due to the wire break of the wire rope protrudes from the outer surface of the wire rope. It is a concept that includes a part of the outer surface where the cross-sectional area of the wire rope is larger than the normal state due to a defect (abnormality) such as a cage-like shape loss. Further, in the present specification, the "protruding portion" includes not only the defect of the wire as described above but also the increase in the cross-sectional area of the wire rope due to foreign matter or grease adhering to the outer surface of the wire rope. It is described as a broad concept. Further, "contacting with the detection coil" is a concept including contacting with the housing (detection coil main body portion) of the detection coil in which the detection coil is arranged, in addition to contact with the detection coil itself.
　この発明の第２の局面におけるワイヤロープ検査システムは、検査対象であるワイヤロープに対して磁界を印加する励磁部と、励磁部により磁界が印加されるワイヤロープに対して相対的に移動しながらワイヤロープの磁束を検知する検知コイルと、ワイヤロープの外表面の少なくとも一部からの飛び出し部分を検知する飛び出し検知部と、飛び出し検知部からの検知信号に基づいて、飛び出し部分が検知コイルに接触する前に、検知コイルをワイヤロープから離間する方向に移動させる駆動部と、を備える、ワイヤロープ検査装置と、検知コイルからの信号に基づいて、ワイヤロープの異常の有無を判定するように構成されている処理装置と、を備え、ワイヤロープ検査装置は、飛び出し検知部からの検知信号に基づいて、飛び出し部分が検知されたことを示す情報を処理装置に出力するように構成されている。 In the wire rope inspection system according to the second aspect of the present invention, the exciting portion that applies a magnetic field to the wire rope to be inspected and the wire rope to which the magnetic field is applied by the exciting portion move relative to each other.

Move it away from the wire rope. As a result, when the protruding portion of the wire rope is detected, the detection coil can be separated from the wire rope before the protruding portion comes into contact with the detection coil. Therefore, even when the detection coil is brought close to the wire rope for inspection in order to accurately detect the magnetic flux of the wire rope, the detection coil can be separated from the wire rope before the detection coil comes into contact with the protruding portion. .. As a result, it is possible to suppress the contact between the portion protruding from the wire rope to be inspected (the protruding portion) and the detection coil while inspecting the wire rope with the detection coil close to each other with high accuracy.

　（全磁束法による異常検知）
　ワイヤロープ検査システム１００は、全磁束法によってワイヤロープＷの異常の有無を判定することにより、目視により確認しにくいワイヤロープＷの異常を確認可能なシステムである。ワイヤロープＷに異常部分（素線断裂、減肉、さびなど）が含まれる場合には、異常部分における磁束が正常部分とは異なる。全磁束法では、ワイヤロープＷの表面の異常部分（素線断線）などからの漏洩磁束を測定する方法と異なり、ワイヤロープＷの内部の異常部分（素線断裂、減肉、さびなど計頭部）をも測定可能な方法である。第１実施形態では、ワイヤロープ検査システム１００は、処理装置１０２に対する検査作業者による入力操作に基づいて、ワイヤロープＷの検査が行われる（開始される）ように構成されている。 (Abnormality detection by total magnetic flux method)
The wire rope inspection system 100 is a system capable of confirming an abnormality in the wire rope W, which is difficult to visually confirm, by determining the presence or absence of an abnormality in the wire rope W by the total magnetic flux method. When the wire rope W contains an abnormal portion (broken wire, thinning, rust, etc.), the magnetic flux in the abnormal portion is different from that in the normal portion. In the total magnetic flux method, unlike the method of measuring the leakage magnetic flux from the abnormal part (wire breakage) on the surface of the wire rope W, the measuring head such as the wire breakage, wall thinning, rust, etc. inside the wire rope W is different. Part) is also a measurable method. In the first embodiment, the wire rope inspection system 100 is configured to inspect (start) the wire rope W based on an input operation by an inspection worker for the processing device 102.
　具体的には、シーブ１０３ｂとシーブ１０３ｃとの間に配置されたワイヤロープ検査装置１０１に対して、シーブ１０３ｂの回転によってワイヤロープＷが図３～図５のＸ２方向に向かって導かれる。ワイヤロープ検査装置１０１に導かれたワイヤロープＷは、まず磁界印加部２０によって、予め磁界が整えられる。そして、励磁部１０の励振コイル１１が、予め磁界の整えられた（整磁された）ワイヤロープＷの磁界（磁束）を励振する。そして、検知部３０の検知コイル３１が、整磁された後に励振された状態のワイヤロープＷの磁束を検知する。すなわち、第１実施形態では、検知コイル３１は、磁界印加部２０により予め磁界が印加された後（整磁された後）に、ワイヤロープＷの磁束を検知するように構成されている。 Specifically, the wire rope W is guided toward the X2 direction of FIGS. 3 to 5 by the rotation of the sheave 103b with respect to the wire rope inspection device 101 arranged between the sheave 103b and the sheave 103c. First, the magnetic field of the wire rope W guided to the wire rope inspection device 101 is prepared in advance by the magnetic field application unit 20. Then, the excitation coil 11 of the exciting portion 10 excites the magnetic field (magnetic flux) of the wire rope W whose magnetic field is arranged (magnetized) in advance. Then, the detection coil 31 of the detection unit 30 detects the magnetic flux of the wire rope W in a state of being excited after being magnetized. That is, in the first embodiment, the detection coil 31 is configured to detect the magnetic flux of the wire rope W after the magnetic field is applied in advance by the magnetic field application unit 20 (after being magnetized).
　図５および図６に示すように、磁界印加部２０は、ワイヤロープＷの延びる方向と直交する方向（Ｚ方向）に配置される１対の磁界印加部２０ａおよび磁界印加部２０ｂを含む。１対の磁界印加部２０ａおよび２０ｂは、ワイヤロープＷを挟み込むようにワイヤロープＷの短手方向（ワイヤロープＷの延びる方向と直交する方向、Ｚ方向）の両側に配置される。具体的には、磁界印加部２０ａは、ワイヤロープＷのＺ１方向側に配置される。そして、磁界印加部２０ｂは、ワイヤロープＷのＺ２方向側に配置される。磁界印加部２０は、たとえば、永久磁石である。磁界印加部２０ａおよび２０ｂは、ワイヤロープＷの磁化の方向を略均一に整えるために、比較的強い磁界を印加することが可能に構成されている。 As shown in FIGS. 5 and 6, the magnetic field application unit 20 includes a pair of magnetic field application units 20a and a magnetic field application unit 20b arranged in a direction (Z direction) orthogonal to the extending direction of the wire rope W. The pair of magnetic field application portions 20a and 20b are arranged on both sides of the wire rope W in the lateral direction (direction orthogonal to the extending direction of the wire rope W, Z direction) so as to sandwich the wire rope W. Specifically, the magnetic field application portion 20a is arranged on the Z1 direction side of the wire rope W. The magnetic field application unit 20b is arranged on the Z2 direction side of the wire rope W. The magnetic field application unit 20 is, for example, a permanent magnet. The magnetic field application portions 20a and 20b are configured to be able to apply a relatively strong magnetic field in order to arrange the magnetization direction of the wire rope W substantially uniformly.
　また、磁界印加部２０は、磁界印加部２０ａのＺ２方向に向けられたＮ極（斜線あり）と磁界印加部２０ｂのＺ１方向に向けられたＮ極（斜線あり）とがワイヤロープＷを挟んで対向するように設けられている。これにより、磁界印加部２０ａおよび２０ｂの間を通過したワイヤロープＷは、磁界印加部２０ａおよび２０ｂにより磁界が印加され、磁化の方向が整えられる。 Further, in the magnetic field application unit 20, the N pole (with diagonal lines) directed in the Z2 direction of the magnetic field application unit 20a and the N pole (with diagonal lines) directed in the Z1 direction of the magnetic field application unit 20b sandwich the wire rope W. It is provided so as to face each other. As a result, the wire rope W that has passed between the magnetic field application portions 20a and 20b is applied with a magnetic field by the magnetic field application portions 20a and 20b, and the direction of magnetization is adjusted.
　励磁部１０は、ワイヤロープＷの延びる方向（Ｘ方向）に沿って巻回された励振コイル１１を含む。励振コイル１１は、図３に示すように、複数（４本）のワイヤロープＷの全てをまとめて巻回するように設けられる。励振コイル１１は、励振交流電流が流れることにより、ワイヤロープＷが延びる方向（Ｘ方向）に沿った磁束（磁界）をコイル内部（コイルの輪の内側）に発生させる。そして、励振コイル１１は、発生させた磁束（磁界）をワイヤロープＷに印加する。具体的には、処理部５１による制御によって励磁部１０（励振コイル１１）に一定の大きさかつ一定の周波数を有する交流電流（励振電流）が流されることにより、ワイヤロープＷの延びる方向（Ｘ方向）に振動する（Ｘ１方向への磁界とＸ２方向への磁界が周期的に現れる）ように磁界が印加される。すなわち、ワイヤロープＷにおいて、磁界印加部２０によって予め整えられた磁界（磁束）が、励磁部１０によって振動させられる。 The exciting portion 10 includes an exciting coil 11 wound along the extending direction (X direction) of the wire rope W. As shown in FIG. 3, the excitation coil 11 is provided so as to wind all of the plurality (4) wire ropes W together. The exciting coil 11 generates a magnetic flux (magnetic field) along the direction in which the wire rope W extends (X direction) inside the coil (inside the ring of the coil) due to the flow of the exciting AC current. Then, the exciting coil 11 applies the generated magnetic flux (magnetic field) to the wire rope W. Specifically, an alternating current (excitation current) having a constant magnitude and a constant frequency is passed through the exciting unit 10 (excitation coil 11) under the control of the processing unit 51, so that the direction in which the wire rope W extends (X). A magnetic field is applied so as to oscillate in the direction (direction) (a magnetic field in the X1 direction and a magnetic field in the X2 direction appear periodically). That is, in the wire rope W, the magnetic field (magnetic flux) prepared in advance by the magnetic field application unit 20 is vibrated by the excitation unit 10.

Each of the first detection coil 31a and the second detection coil 31b is provided so as to cover half a circumference of the wire rope W. Therefore, by combining the first detection coil 31a and the second detection coil 31b, the detection coil 31 that surrounds the wire rope W over the entire circumference is configured. Further, the detection coil 31 (the first detection coil 31a and the second detection coil 31b) is each composed of a conductor pattern provided on the flexible substrate. Further, the first detection coil 31a and the second detection coil 31b are provided so as to be wound along the extending direction of the wire rope W. That is, the detection coil 31 is provided so as to be wound around the entire circumference by two saddle-shaped coils along the extending direction (X direction) of the wire rope W. In addition, in this specification, "winding" means not only winding (winding) over one turn or more, but also winding by the number of times (angle) of one turn or less (for example, half a turn). It is described as a concept including.
　また、第１検知コイル３１ａと第２検知コイル３１ｂの各々は、ワイヤロープＷの延びる方向（Ｘ方向）に沿って巻回するように設けられていることにより、ワイヤロープＷの延びる方向（Ｘ方向）に沿ってコイルの内側を貫く向きの磁束を検知（測定）する。すなわち、検知コイル３１（第１検知コイル３１ａおよび第２検知コイル３１ｂ）は、励磁部１０（励振コイル１１）によって周期的に時間変化させられる磁束（磁界）の変化を検知するように構成されている。また、検知コイル３１（第１検知コイル３１ａおよび第２検知コイル３１ｂ）は、検知した磁束を示す磁束信号を制御基板５０の磁束信号取得部５２に対して出力する。すなわち、４本のワイヤロープＷに対して磁束の検知を行った場合には、合計で８個の磁束信号が磁束信号取得部５２によって取得される。 Further, each of the first detection coil 31a and the second detection coil 31b is provided so as to be wound along the extending direction (X direction) of the wire rope W, so that the extending direction (X) of the wire rope W is provided.

There is. Further, the detection coil 31 (first detection coil 31a and second detection coil 31b) outputs a magnetic flux signal indicating the detected magnetic flux to the magnetic flux signal acquisition unit 52 of the control board 50. That is, when the magnetic flux is detected for the four wire ropes W, a total of eight magnetic flux signals are acquired by the magnetic flux signal acquisition unit 52.
　ここで、ワイヤロープ検査システム１００では、エレベータ１０３は、人および積み荷を載置した状態で動作する通常運転時と、検知コイル３１によって磁束を測定することによってワイヤロープＷの検査を行う検査運転時とにおいて、エレベータ１０３の動作速度（運転速度）を異ならせる（運転モードを変更する）ように構成されている。たとえば、通常運転時には、運転速度（検知コイル３１に対するワイヤロープＷの相対速度）が５００ｍ／分程度であり、検査運転時には、運転速度（検知コイル３１に対するワイヤロープＷの相対速度）は１０ｍ／分以上４０ｍ／分以下程度である。また、ワイヤロープＷの振動（片側振動幅）は、エレベータ１０３の運転速度に応じて大きくなる。たとえば、ワイヤロープＷの直径が１０ｍｍの場合において、通常運転時におけるワイヤロープＷの片側振動幅は１３ｍｍ程度、検査運転時におけるワイヤロープＷの振動幅は３ｍｍ程度である。 Here, in the wire rope inspection system 100, in the normal operation in which the elevator 103 operates with a person and a load placed on it, and in the inspection operation in which the wire rope W is inspected by measuring the magnetic flux by the detection coil 31.

It is about 40 m / min or less. Further, the vibration of the wire rope W (vibration width on one side) increases according to the operating speed of the elevator 103. For example, when the diameter of the wire rope W is 10 mm, the vibration width on one side of the wire rope W during normal operation is about 13 mm, and the vibration width of the wire rope W during inspection operation is about 3 mm.
　図８および図９に示すように、検知コイル３１は、ワイヤロープＷとの距離（コイル離間距離Ｄ１）を変更可能に構成されている。具体的には、第１実施形態では、図８に示すように、駆動部４０は、エレベータ１０３の通常運転時には、検知コイル３１とワイヤロープＷとの距離であるコイル離間距離Ｄ１を大きくするように構成されている。そして、図９に示すように、駆動部４０は、通常運転時よりも運転速度の小さい検査運転時には、コイル離間距離Ｄ１を通常運転時よりも小さくするように検知コイル３１を移動させるように構成されている。すなわち、検査運転時には、検知コイル３１（第１検知コイル３１ａおよび第２検知コイル３１ｂ）は、検査対象であるワイヤロープＷに可能な限り近づけた配置となる。そして、コイル離間距離Ｄ１を小さくした状態で、検知コイル３１によるワイヤロープＷの磁束の検知が行われる。 As shown in FIGS. 8 and 9, the detection coil 31 is configured so that the distance from the wire rope W (coil separation distance D1) can be changed.

That is, during the inspection operation, the detection coils 31 (the first detection coil 31a and the second detection coil 31b) are arranged as close as possible to the wire rope W to be inspected. Then, the magnetic flux of the wire rope W is detected by the detection coil 31 with the coil separation distance D1 reduced.

For example, if one of the plurality of strands constituting the wire rope W is broken (cut), the wire rope W may be in a state of protruding from the outer surface. The pop-out detection unit 32 according to the first embodiment is configured to detect the pop-out portion Wa of the wire rope W as described above before the pop-out portion Wa comes into contact with the detection coil 31 (detection main body portion 33). ..

　図１０に示すように、第１実施形態では、飛び出し検知部３２は、ワイヤロープＷを取り囲むように配置される。具体的には、飛び出し検知部３２は、ワイヤロープＷが延びる方向と直交する方向（Ｚ１方向側）に配置されている第１部分３２ａと、ワイヤロープＷに対して第１部分３２ａが配置される側とは反対側（Ｚ２方向側）において第１部分３２ａとともにワイヤロープＷを取り囲むように配置されている第２部分３２ｂとを含む。 <Structure of pop-out detector>
As shown in FIG. 10, in the first embodiment, the pop-out detection unit 32 is arranged so as to surround the wire rope W. Specifically, the pop-out detection unit 32 has a first portion 32a arranged in a direction orthogonal to the direction in which the wire rope W extends (Z1 direction side) and a first portion 32a arranged with respect to the wire rope W. It includes the first portion 32a and the second portion 32b arranged so as to surround the wire rope W on the side opposite to the side facing the wire rope (Z2 direction side).
　図１１に示すように、飛び出し検知部３２（第１部分３２ａおよび第２部分３２ｂ）は、折り曲げ部分３２Ｍにおいて折り曲げられている板状の導体である。そして、第１部分３２ａおよび第２部分３２ｂは、板状の導体の端部がさらに折り曲げられて互いに面接触する平面の接触面３２Ｎを有する。飛び出し検知部３２は、たとえば、ステンレスまたは銅板などの金属の板である。また、図１１（Ｂ）に示すように、第１部分３２ａと第２部分３２ｂとの各々は、弾性変形しながら接触している。すなわち、第１部分３２ａと第２部分３２ｂの各々は、板バネ構造となっており、弾性変形された板バネ構造による復元力によって互いに向かい合う方向に付勢された状態で接触面３２Ｎが面接触している。 As shown in FIG. 11, the pop-out detection unit 32 (first portion 32a and second portion 32b) is a plate-shaped conductor that is bent at the bent portion 32M. The first portion 32a and the second portion 32b have a flat contact surface 32N in which the end portions of the plate-shaped conductors are further bent and come into surface contact with each other. The pop-out detection unit 32 is, for example, a metal plate such as stainless steel or a copper plate. Further, as shown in FIG. 11B, each of the first portion 32a and the second portion 32b are in contact with each other while being elastically deformed. That is, each of the first portion 32a and the second portion 32b has a leaf spring structure, and the contact surface 32N is in surface contact with each other in a state of being urged in directions facing each other by the restoring force of the elastically deformed leaf spring structure. is doing.
　また、第１部分３２ａおよび第２部分３２ｂは、ワイヤロープＷの延びる方向（Ｘ方向）から、ワイヤロープＷの延びる方向と交差する面（ＹＺ平面）に沿ってワイヤロープＷ側（Ｚ２方向側またはＺ１方向側）に折り曲げられている。そして、第１部分３２ａおよび第２部分３２ｂは、第１部分３２ａと第２部分３２ｂとが互いに接触する端部に設けられた半円形の切り欠きによってワイヤロープＷを取り囲むよう構成されている。すなわち、飛び出し検知部３２は、それぞれ半円形の切り欠きを有する第１部分３２ａと第２部分３２ｂとがワイヤロープＷを取り囲むことによって、ワイヤロープＷの全周に亘って飛び出し部分Ｗａを検知するように構成されている。 Further, the first portion 32a and the second portion 32b are on the wire rope W side (Z2 direction side) along a surface (YZ plane) intersecting the extending direction of the wire rope W from the extending direction (X direction) of the wire rope W. Or it is bent in the Z1 direction side). The first portion 32a and the second portion 32b are configured to surround the wire rope W by a semicircular notch provided at an end where the first portion 32a and the second portion 32b are in contact with each other. That is, the pop-out detection unit 32 detects the pop-out portion Wa over the entire circumference of the wire rope W by the first portion 32a and the second portion 32b, each having a semicircular notch, surrounding the wire rope W. It is configured as follows.
　また、第１実施形態では、板状の部材である飛び出し検知部３２は、複数（４本）のワイヤロープＷの各々の飛び出し部分Ｗａを共通して検知するように構成されている。すなわち、飛び出し検知部３２は、共通の第１部分３２ａおよび第２部分３２ｂによって、４本のワイヤロープＷのうちのいずれかの外表面から飛び出し部分Ｗａが発生している場合に、飛び出し部分Ｗａを検知するように構成されている。 Further, in the first embodiment, the pop-out detection unit 32, which is a plate-shaped member, is configured to commonly detect each pop-out portion Wa of the plurality of (4) wire ropes W. That is, in the pop-out detection unit 32, when the pop-out portion Wa is generated from the outer surface of any one of the four wire ropes W by the common first portion 32a and the second portion 32b, the pop-out portion Wa Is configured to detect.
　そして、図１２に示すように、第１実施形態では、飛び出し検知部３２（第１部分３２ａおよび第２部分３２ｂ）は、ワイヤロープＷの飛び出し部分Ｗａに接触することによって、飛び出し部分Ｗａを検知するように構成されている。具体的には、第１部分３２ａおよび第２部分３２ｂは、ワイヤロープＷを取り囲みながら互いに接触して電気的に導通した状態で配置されている。飛び出し検知部３２は、第１部分３２ａと第２部分３２ｂとのそれぞれの接触面３２Ｎ同士が面接触することによって、第１部分３２ａと第２部分３２ｂとが導通するように構成されている。そして、飛び出し検知部３２は、飛び出し部分Ｗａとの接触により第１部分３２ａおよび第２部分３２ｂの少なくとも一方の位置がずれることに起因して、第１部分３２ａと第２部分３２ｂとの導通が遮断された場合に、飛び出し部分Ｗａを検知するように構成されている。第１部分３２ａおよび第２部分３２ｂは、飛び出し部分Ｗａとの接触により弾性変形して位置がずれる。 Then, as shown in FIG. 12, in the first embodiment, the pop-out detection unit 32 (first portion 32a and second portion 32b) detects the pop-out portion Wa by contacting the pop-out portion Wa of the wire rope W. It is configured to do. Specifically, the first portion 32a and the second portion 32b are arranged in a state of being in contact with each other and electrically conducting while surrounding the wire rope W. The pop-out detection unit 32 is configured such that the first portion 32a and the second portion 32b are electrically connected to each other by surface contact between the contact surfaces 32N of the first portion 32a and the second portion 32b. Then, in the pop-out detection unit 32, the conduction between the first portion 32a and the second portion 32b is caused by the displacement of at least one of the first portion 32a and the second portion 32b due to the contact with the pop-out portion Wa. It is configured to detect the protruding portion Wa when it is blocked. The first portion 32a and the second portion 32b are elastically deformed and displaced due to contact with the protruding portion Wa.
　具体的には、第１部分３２ａと第２部分３２ｂとの各々には、図示しないリード線が電気的に接続されている。そして、第１部分３２ａおよび第２部分３２ｂは、制御基板５０の検知回路５３にリード線を介して接続されている。これにより、検知回路５３によって第１部分３２ａと第２部分３２ｂとの導通が判定される。 Specifically, lead wires (not shown) are electrically connected to each of the first portion 32a and the second portion 32b. The first portion 32a and the second portion 32b are connected to the detection circuit 53 of the control board 50 via a lead wire. As a result, the detection circuit 53 determines the continuity between the first portion 32a and the second portion 32b.
　また、図８および図９に示すように、飛び出し検知部３２は、ワイヤロープＷからの離間距離である検知部離間距離Ｄ２を変更可能に構成されている。すなわち、第１部分３２ａと第２部分３２ｂとの各々は、検知部離間距離Ｄ２を変更可能に構成されている。具体的には、飛び出し検知部３２（第１部分３２ａおよび第２部分３２ｂ）は、検知コイル３１と一体的に構成されているため、駆動部４０の動作によって検知コイル３１のコイル離間距離Ｄ１が変更された場合に、同様に検知部離間距離Ｄ２が変更される。すなわち、コイル離間距離Ｄ１と同様に、飛び出し検知部３２は、検知コイル３１による検知を行わないエレベータ１０３の通常運転時には、検知部離間距離Ｄ２が検査運転時よりも大きくなるように配置される。そして、飛び出し検知部３２は、検査運転時には、検知部離間距離Ｄ２を小さくするように構成されている。 Further, as shown in FIGS. 8 and 9, the pop-out detection unit 32 is configured so that the detection unit separation distance D2, which is the separation distance from the wire rope W, can be changed. That is, each of the first portion 32a and the second portion 32b is configured so that the detection unit separation distance D2 can be changed. Specifically, since the pop-out detection unit 32 (first portion 32a and second portion 32b) is integrally configured with the detection coil 31, the coil separation distance D1 of the detection coil 31 is increased by the operation of the drive unit 40. When changed, the detection unit separation distance D2 is similarly changed. That is, similarly to the coil separation distance D1, the pop-out detection unit 32 is arranged so that the detection unit separation distance D2 becomes larger during the normal operation of the elevator 103 that does not detect by the detection coil 31 than during the inspection operation. The pop-out detection unit 32 is configured to reduce the detection unit separation distance D2 during the inspection operation.
　また、図１０に示すように、第１実施形態では、飛び出し検知部３２は、検知コイル３１によってワイヤロープＷの磁束の検知を行う検査運転時の場合に、ワイヤロープＷからの離間距離である検知部離間距離Ｄ２が検知コイル３１とワイヤロープＷとの離間距離であるコイル離間距離Ｄ１以下の大きさとなるように配置される。 Further, as shown in FIG. 10, in the first embodiment, the pop-out detection unit 32 is a distance from the wire rope W in the case of an inspection operation in which the magnetic flux of the wire rope W is detected by the detection coil 31. The detection unit separation distance D2 is arranged so as to have a size equal to or less than the coil separation distance D1 which is the separation distance between the detection coil 31 and the wire rope W.
　すなわち、検査運転時において、検知コイル３１の第１検知コイル３１ａと第２検知コイル３１ｂとがワイヤロープＷを取り囲むことによって円形状（円柱形状）の孔部が形成される。また、飛び出し検知部３２においても同様に、第１部分３２ａと第２部分３２ｂとがワイヤロープＷを取り囲むように配置されることによって、円形状の孔部が形成される。ワイヤロープ検査装置１０１では、この飛び出し検知部３２による孔部の大きさ（直径）が、検知コイル３１による孔部の大きさ（直径）以下の大きさになるように構成されている。したがって、検査運転時において、飛び出し検知部３２は、ワイヤロープＷからの距離が検知コイル３１と同じ位置、または、検知コイル３１よりもワイヤロープＷに近い位置に配置される。 That is, during the inspection operation, the first detection coil 31a and the second detection coil 31b of the detection coil 31 surround the wire rope W to form a circular (cylindrical) hole. Similarly, in the pop-out detection unit 32, the first portion 32a and the second portion 32b are arranged so as to surround the wire rope W, whereby a circular hole portion is formed. The wire rope inspection device 101 is configured such that the size (diameter) of the hole formed by the pop-out detection unit 32 is equal to or smaller than the size (diameter) of the hole formed by the detection coil 31. Therefore, during the inspection operation, the pop-out detection unit 32 is arranged at the same position as the detection coil 31 at a distance from the wire rope W, or at a position closer to the wire rope W than the detection coil 31.
　〈飛び出し部分を検知した場合の動作〉
　検査運転時において、検知コイル３１は、ワイヤロープＷに可能な限り近づくように配置されている。そこで、ワイヤロープ検査装置１０１は、上記のように、飛び出し部分Ｗａが発生している場合に、飛び出し部分Ｗａと接触しないように検知コイル３１を回避（退避）させるように構成されている。 <Operation when a protruding part is detected>
During the inspection operation, the detection coil 31 is arranged so as to be as close as possible to the wire rope W. Therefore, as described above, the wire rope inspection device 101 is configured to avoid (retract) the detection coil 31 so as not to come into contact with the protruding portion Wa when the protruding portion Wa is generated.
　具体的には、第１実施形態では、駆動部４０は、飛び出し検知部３２からの検知信号に基づいて、飛び出し検知部３２（第１部分３２ａおよび第２部分３２ｂ）をワイヤロープＷから離間する方向に移動させる。また、駆動部４０は、飛び出し検知部３２からの検知信号に基づいて、飛び出し部分Ｗａが検知コイル３１に接触する前に、検知コイル３１（第１検知コイル３１ａおよび第２検知コイル３１ｂ）をワイヤロープＷから離間する方向に移動させる。 Specifically, in the first embodiment, the drive unit 40 separates the pop-out detection unit 32 (first portion 32a and second portion 32b) from the wire rope W based on the detection signal from the pop-out detection unit 32. Move in the direction. Further, the drive unit 40 wires the detection coil 31 (first detection coil 31a and second detection coil 31b) based on the detection signal from the pop-out detection unit 32 before the pop-out portion Wa comes into contact with the detection coil 31. Move in the direction away from the rope W.
　すなわち、第１実施形態では、駆動部４０は、飛び出し検知部３２からの検知信号に基づいて、接続部３３ａによって接続された検知コイル３１および飛び出し検知部３２を、ワイヤロープＷから離間する方向に一体的に移動させる。詳細には、駆動部４０は、複数（４本）のワイヤロープＷのうちの少なくとも１つのワイヤロープＷの外表面からの飛び出し部分Ｗａが検知されたことによる飛び出し検知部３２からの検知信号に基づいて、複数のワイヤロープＷの各々に設けられた検知コイル３１の全てを一体的にワイヤロープＷから離間する方向に移動させるように構成されている。たとえば、駆動部４０は、飛び出し検知部３２からの検知信号に基づいて、コイル離間距離Ｄ１および検知部離間距離Ｄ２を、検査運転時の大きさから通常運転時の大きさまで大きくすることによって、検知コイル３１および飛び出し検知部３２が飛び出し部分Ｗａと接触することを回避する。 That is, in the first embodiment, the drive unit 40 separates the detection coil 31 and the pop-out detection unit 32 connected by the connection unit 33a from the wire rope W based on the detection signal from the pop-out detection unit 32. Move in one piece. Specifically, the drive unit 40 receives a detection signal from the protrusion detection unit 32 due to the detection of the protrusion portion Wa from the outer surface of at least one of the plurality (four) wire ropes W. Based on this, all of the detection coils 31 provided in each of the plurality of wire ropes W are configured to be integrally moved in a direction away from the wire ropes W. For example, the drive unit 40 detects by increasing the coil separation distance D1 and the detection unit separation distance D2 from the size during inspection operation to the size during normal operation based on the detection signal from the pop-out detection unit 32. It is possible to prevent the coil 31 and the pop-out detection unit 32 from coming into contact with the pop-out portion Wa.
　また、第１実施形態では、飛び出し検知部３２（第１部分３２ａおよび第２部分３２ｂ）は、ワイヤロープＷの延びる方向（Ｘ方向）において、検知コイル３１よりもワイヤロープＷの上流側（Ｘ１方向側）に設けられている。具体的には、飛び出し部分Ｗａが検知された場合に、検知された飛び出し部分Ｗａが検知コイル３１に接触する前に退避可能な距離分だけ、検知コイル３１から上流側に離間した位置に飛び出し検知部３２が配置される。たとえば、検査運転時のコイル離間距離Ｄ１から通常運転時のコイル離間距離Ｄ１まで検知コイル３１が移動（退避）するために、飛び出し検知部３２から検知コイル３１の位置まで、検査運転時のワイヤロープＷの移動速度において０．５秒でワイヤロープＷが移動する距離分以上離間させて飛び出し検知部３２を配置する。たとえば、検査運転時において、ワイヤロープＷが、３０ｍ／分の移動速度で移動している場合には、飛び出し検知部３２は、検知コイル３１からワイヤロープＷの上流側に２５ｃｍ以上離間した位置に配置される。また、ワイヤロープＷが、１５ｍ／分の移動速度で移動している場合には、飛び出し検知部３２は、検知コイル３１からワイヤロープＷの上流側に１２．５ｃｍ以上離間した位置に配置される。 Further, in the first embodiment, the pop-out detection unit 32 (first portion 32a and second portion 32b) is on the upstream side (X1) of the wire rope W with respect to the detection coil 31 in the extending direction (X direction) of the wire rope W. It is provided on the direction side). Specifically, when the pop-out portion Wa is detected, the pop-out portion is detected at a position separated from the detection coil 31 on the upstream side by a distance that can be retracted before the detected pop-out portion Wa comes into contact with the detection coil 31. The unit 32 is arranged. For example, in order to move (retract) the detection coil 31 from the coil separation distance D1 during the inspection operation to the coil separation distance D1 during the normal operation, the wire rope during the inspection operation from the pop-out detection unit 32 to the position of the detection coil 31. The pop-out detection unit 32 is arranged so as to be separated by the distance that the wire rope W moves in 0.5 seconds at the moving speed of W. For example, when the wire rope W is moving at a moving speed of 30 m / min during the inspection operation, the pop-out detection unit 32 is located at a position 25 cm or more away from the detection coil 31 on the upstream side of the wire rope W. Be placed. When the wire rope W is moving at a moving speed of 15 m / min, the pop-out detection unit 32 is arranged at a position separated from the detection coil 31 on the upstream side of the wire rope W by 12.5 cm or more. ..
　図１３に示すように、検知回路５３は、第１部分３２ａと第２部分３２ｂとの導通が遮断された場合に、飛び出し部分Ｗａが検知されたことを示す信号を駆動回路５４と、処理部５１とに出力する。すなわち、飛び出し検知部３２自体が、スイッチとして機能することによって、駆動部４０が動作するように構成されている。駆動回路５４は、検知回路５３からの入力に基づいて、駆動部４０を動作させる。また、処理部５１は、検知回路５３および駆動回路５４からの信号を取得可能に構成されている。そして、ワイヤロープ検査装置１０１は、飛び出し検知部３２からの検知信号に基づいて、飛び出し部分Ｗａが検知されたことを示す情報を処理装置１０２に出力するように構成されている。具体的には、処理部５１は、取得した飛び出し部分Ｗａの検知に関する情報をエレベータ１０３の制御装置１０３ｄと、処理装置１０２の制御部１０２ｂに対して、通信部５５を介して出力する。 As shown in FIG. 13, the detection circuit 53 sends a signal indicating that the protruding portion Wa is detected when the continuity between the first portion 32a and the second portion 32b is cut off, and the processing unit. Output to 51. That is, the pop-out detection unit 32 itself is configured to operate the drive unit 40 by functioning as a switch. The drive circuit 54 operates the drive unit 40 based on the input from the detection circuit 53. Further, the processing unit 51 is configured to be able to acquire signals from the detection circuit 53 and the drive circuit 54. Then, the wire rope inspection device 101 is configured to output information indicating that the pop-out portion Wa has been detected to the processing device 102 based on the detection signal from the pop-out detection unit 32. Specifically, the processing unit 51 outputs the acquired information regarding the detection of the pop-out portion Wa to the control device 103d of the elevator 103 and the control unit 102b of the processing device 102 via the communication unit 55.
　また、ワイヤロープ検査システム１００は、飛び出し検知部３２によって飛び出し部分Ｗａが検知された場合に、検知コイル３１をワイヤロープＷから離間する方向に移動させるとともに、エレベータ１０３の動作を停止させるように構成されている。具体的には、飛び出し検知部３２によって飛び出し部分Ｗａが検知された場合に、処理部５１からの飛び出し部分Ｗａが検知されたことを示す情報としてのエレベータ停止指令信号が、信号増幅回路によって増幅されてエレベータ１０３の制御装置１０３ｄに出力される。そして、制御装置１０３ｄは、取得されたエレベータ停止指令信号に基づいて、エレベータ１０３の動作を停止させる。 Further, the wire rope inspection system 100 is configured to move the detection coil 31 in a direction away from the wire rope W and stop the operation of the elevator 103 when the protrusion detection unit 32 detects the protrusion portion Wa. Has been done. Specifically, when the pop-out portion Wa is detected by the pop-out detection unit 32, the elevator stop command signal as information indicating that the pop-out portion Wa from the processing unit 51 is detected is amplified by the signal amplification circuit. Is output to the control device 103d of the elevator 103. Then, the control device 103d stops the operation of the elevator 103 based on the acquired elevator stop command signal.
　また、図１４に示すように、処理部５１は、通信部５５を介して、飛び出し部分Ｗａが検知されたことを示す情報を処理装置１０２に送信する。そして、処理装置１０２の制御部１０２ｂは、取得された情報に基づいて、飛び出し部分Ｗａの検知を示す情報を表示部１０２ｄに表示させるとともに、報知部１０２ｅに報知させる。 Further, as shown in FIG. 14, the processing unit 51 transmits information indicating that the pop-out portion Wa has been detected to the processing device 102 via the communication unit 55. Then, the control unit 102b of the processing device 102 causes the display unit 102d to display the information indicating the detection of the pop-out portion Wa based on the acquired information, and causes the notification unit 102e to notify the information.
　（第１実施形態の効果）
　第１実施形態のワイヤロープ検査システム１００およびワイヤロープ検査装置１０１では、以下のような効果を得ることができる。 (Effect of the first embodiment)
In the wire rope inspection system 100 and the wire rope inspection device 101 of the first embodiment, the following effects can be obtained.
　第１実施形態のワイヤロープ検査システム１００およびワイヤロープ検査装置１０１では、上記のように、飛び出し検知部３２からの検知信号に基づいて、飛び出し部分Ｗａが検知コイル３１に接触する前に、検知コイル３１をワイヤロープＷから離間する方向に移動させる。これにより、ワイヤロープＷの飛び出し部分Ｗａが検知された場合に、飛び出し部分Ｗａが検知コイル３１に接触する前に、検知コイル３１をワイヤロープＷから離間させることができる。そのため、ワイヤロープＷの磁束を精度よく検知するために検知コイル３１をワイヤロープＷに近づけて検査を行う場合にも、検知コイル３１が飛び出し部分Ｗａに接触する前に、検知コイル３１をワイヤロープＷから離間させることができる。その結果、検知コイル３１を近づけてワイヤロープＷの検査を精度よく行いながら、検査対象であるワイヤロープＷから飛び出した部分（飛び出し部分Ｗａ）と検知コイル３１との接触を抑制することができる。 In the wire rope inspection system 100 and the wire rope inspection device 101 of the first embodiment, as described above, based on the detection signal from the pop-out detection unit 32, the detection coil is before the pop-out portion Wa comes into contact with the detection coil 31. 31 is moved in a direction away from the wire rope W. As a result, when the protruding portion Wa of the wire rope W is detected, the detection coil 31 can be separated from the wire rope W before the protruding portion Wa comes into contact with the detection coil 31. Therefore, even when the detection coil 31 is brought close to the wire rope W for inspection in order to accurately detect the magnetic flux of the wire rope W, the detection coil 31 is connected to the wire rope before the detection coil 31 comes into contact with the protruding portion Wa. It can be separated from W. As a result, it is possible to suppress the contact between the portion protruding from the wire rope W to be inspected (the protruding portion Wa) and the detection coil 31 while the detection coil 31 is brought close to the wire rope W to inspect the wire rope W with high accuracy.
　また、第１実施形態では、以下のように構成したことによって、更なる効果が得られる。 Further, in the first embodiment, a further effect can be obtained by configuring as follows.
　すなわち、第１実施形態では、飛び出し検知部３２は、ワイヤロープＷを取り囲むように配置される。このように構成すれば、ワイヤロープＷを取り囲むように飛び出し検知部３２が配置されているため、ワイヤロープＷの全周に亘って飛び出し部分Ｗａを検知することができる。そのため、ワイヤロープＷの全周のうちの一部の方向に飛び出し検知部３２が配置されている場合と異なり、ワイヤロープＷの飛び出し部分Ｗａの見落としを抑制することができる。その結果、検知コイル３１と飛び出し部分Ｗａとの接触を効果的に抑制することができる。また、第１実施形態では、飛び出し検知部３２は、ワイヤロープＷからの離間距離である検知部離間距離Ｄ２を変更可能に構成されている。ここで、検知コイル３１によってワイヤロープＷの磁束を測定せずにワイヤロープＷを移動させる場合には、ワイヤロープＷの移動速度を大きくする場合がある。その場合には、移動速度が大きくなるためワイヤロープＷの振動の幅が大きくなる。これに対して、第１実施形態では、飛び出し検知部３２を、ワイヤロープＷからの離間距離である検知部離間距離Ｄ２を変更可能に構成するため、ワイヤロープＷの移動速度を大きくして振動の幅が大きくなる場合に、飛び出し検知部３２をワイヤロープＷから離間した位置に配置させることができる。そのため、ワイヤロープＷの移動速度を大きくする場合に、検知部離間距離Ｄ２を大きくすることによって、飛び出し検知部３２がワイヤロープＷと接触することを抑制することができる。 That is, in the first embodiment, the pop-out detection unit 32 is arranged so as to surround the wire rope W. With this configuration, since the pop-out detection unit 32 is arranged so as to surround the wire rope W, the pop-out portion Wa can be detected over the entire circumference of the wire rope W. Therefore, unlike the case where the pop-out detection unit 32 is arranged in a part of the entire circumference of the wire rope W, it is possible to suppress oversight of the pop-out portion Wa of the wire rope W. As a result, the contact between the detection coil 31 and the protruding portion Wa can be effectively suppressed. Further, in the first embodiment, the pop-out detection unit 32 is configured so that the detection unit separation distance D2, which is the separation distance from the wire rope W, can be changed. Here, when the wire rope W is moved without measuring the magnetic flux of the wire rope W by the detection coil 31, the moving speed of the wire rope W may be increased. In that case, since the moving speed is increased, the width of vibration of the wire rope W is increased. On the other hand, in the first embodiment, the pop-out detection unit 32 is configured so that the detection unit separation distance D2, which is the separation distance from the wire rope W, can be changed, so that the movement speed of the wire rope W is increased and vibration occurs. When the width of the wire rope becomes large, the pop-out detection unit 32 can be arranged at a position separated from the wire rope W. Therefore, when the moving speed of the wire rope W is increased, the protrusion detection unit 32 can be prevented from coming into contact with the wire rope W by increasing the detection unit separation distance D2.
　また、第１実施形態では、飛び出し検知部３２は、ワイヤロープＷが延びる方向と直交する方向に配置されている第１部分３２ａと、ワイヤロープＷに対して第１部分３２ａが配置される側とは反対側において第１部分３２ａとともにワイヤロープＷを取り囲むように配置されている第２部分３２ｂとを含み、第１部分３２ａと第２部分３２ｂとの各々は、検知部離間距離Ｄ２を変更可能に構成されている。このように構成すれば、飛び出し検知部３２が第１部分３２ａと第２部分３２ｂとの２つに分割されて構成されているので、第１部分３２ａおよび第２部分３２ｂをワイヤロープＷの両側から挟み込むように配置することによって、飛び出し検知部３２によってワイヤロープＷを容易に取り囲むことができる。そのため、飛び出し検知部３２が、１つの部材によってワイヤロープＷを取り囲む場合に比べて、第１部分３２ａおよび第２部分３２ｂによってワイヤロープＷを容易に取り囲むことができる。 Further, in the first embodiment, the pop-out detection unit 32 has a first portion 32a arranged in a direction orthogonal to the direction in which the wire rope W extends, and a side on which the first portion 32a is arranged with respect to the wire rope W. The first portion 32a and the second portion 32b arranged so as to surround the wire rope W on the opposite side thereof are included, and each of the first portion 32a and the second portion 32b changes the detection unit separation distance D2. It is configured to be possible. With this configuration, the pop-out detection unit 32 is divided into two parts, a first portion 32a and a second portion 32b, so that the first portion 32a and the second portion 32b are both sides of the wire rope W. By arranging the wire rope so as to be sandwiched from the wire rope W, the wire rope W can be easily surrounded by the pop-out detection unit 32. Therefore, the pop-out detection unit 32 can easily surround the wire rope W by the first portion 32a and the second portion 32b as compared with the case where the wire rope W is surrounded by one member.
　また、第１実施形態では、第１部分３２ａおよび第２部分３２ｂは、ワイヤロープＷの延びる方向において、検知コイル３１よりもワイヤロープＷの上流側に設けられており、ワイヤロープＷの飛び出し部分Ｗａに接触することによって、飛び出し部分Ｗａを検知するように構成されており、駆動部４０は、第１部分３２ａおよび第２部分３２ｂの少なくとも一方が飛び出し部分Ｗａに接触したことによる検知信号に基づいて、飛び出し部分Ｗａが検知コイル３１に接触する前に、検知コイル３１をワイヤロープＷから離間する方向に移動させるように構成されている。このように構成すれば、検知コイル３１に接触する可能性のある飛び出し部分Ｗａを、検知コイル３１よりも上流側の第１部分３２ａおよび第２部分３２ｂの少なくとも一方が先に接触することによって検知することができる。そのため、飛び出し部分Ｗａと検知コイル３１とが接触する前に、検知コイル３１をワイヤロープＷから離間する方向に容易に移動させることができる。その結果、検知コイル３１と飛び出し部分Ｗａとの接触を容易に抑制することができる。 Further, in the first embodiment, the first portion 32a and the second portion 32b are provided on the upstream side of the wire rope W with respect to the detection coil 31 in the extending direction of the wire rope W, and the protruding portion of the wire rope W. The drive unit 40 is configured to detect the protruding portion Wa by contacting the Wa, and the drive unit 40 is based on a detection signal caused by contact of at least one of the first portion 32a and the second portion 32b with the protruding portion Wa. The detection coil 31 is configured to move in a direction away from the wire rope W before the protruding portion Wa comes into contact with the detection coil 31. With this configuration, the protruding portion Wa that may come into contact with the detection coil 31 is detected by first contacting at least one of the first portion 32a and the second portion 32b on the upstream side of the detection coil 31. can do. Therefore, the detection coil 31 can be easily moved in the direction away from the wire rope W before the protruding portion Wa and the detection coil 31 come into contact with each other. As a result, the contact between the detection coil 31 and the protruding portion Wa can be easily suppressed.
　また、第１実施形態では、第１部分３２ａおよび第２部分３２ｂは、折り曲げられている板状の導体であって、ワイヤロープＷを取り囲みながら互いに接触して電気的に導通した状態で配置されており、飛び出し検知部３２は、飛び出し部分Ｗａとの接触によって第１部分３２ａおよび第２部分３２ｂの少なくとも一方の位置がずれることに起因して、第１部分３２ａと第２部分３２ｂとの導通が遮断された場合に、飛び出し部分Ｗａを検知するように構成されている。このように構成すれば、第１部分３２ａと第２部分３２ｂとの導通が遮断されたことに基づいて、第１部分３２ａおよび第２部分３２ｂの少なくとも一方の位置がずれたことを容易に検知することができる。そのため、第１部分３２ａおよび第２部分３２ｂの少なくとも一方と飛び出し部分Ｗａとの接触があったことを容易に検知することができる。その結果、ワイヤロープＷの外表面からの飛び出し部分Ｗａを容易に検知することができるので、飛び出し部分Ｗａと検知コイル３１との接触をより容易に抑制することができる。 Further, in the first embodiment, the first portion 32a and the second portion 32b are bent plate-shaped conductors, and are arranged in a state of being in contact with each other and electrically conducting while surrounding the wire rope W. The pop-out detection unit 32 is connected to the first portion 32a and the second portion 32b due to the displacement of at least one of the first portion 32a and the second portion 32b due to the contact with the pop-out portion Wa. Is configured to detect the pop-out portion Wa when is blocked. With this configuration, it is easy to detect that at least one of the first portion 32a and the second portion 32b is displaced based on the fact that the conduction between the first portion 32a and the second portion 32b is cut off. can do. Therefore, it can be easily detected that at least one of the first portion 32a and the second portion 32b is in contact with the protruding portion Wa. As a result, the protruding portion Wa from the outer surface of the wire rope W can be easily detected, so that the contact between the protruding portion Wa and the detection coil 31 can be more easily suppressed.
　また、第１実施形態では、飛び出し検知部３２は、飛び出し部分Ｗａとの接触によって第１部分３２ａおよび第２部分３２ｂの少なくとも一方が弾性変形することによって位置がずれることに起因して、第１部分３２ａと第２部分３２ｂとの導通が遮断された場合に、飛び出し部分Ｗａを検知するように構成されている。このように構成すれば、第１部分３２ａおよび第２部分３２ｂが弾性変形することによって位置がずれるように構成されているため、ヒンジなどの位置を変更させるための構成を設ける場合と異なり、装置構成の複雑化を抑制することができる。また、弾性変形によって第１部分３２ａおよび第２部分３２ｂの位置がずれるので、飛び出し部分Ｗａとの接触後に第１部分３２ａおよび第２部分３２ｂが元の位置に容易に戻ることができる。そのため、一度飛び出し部分Ｗａを検知した後に再び検査を行う場合に、第１部分３２ａおよび第２部分３２ｂを元の位置に戻すための構成を設けることなく、第１部分３２ａと第２部分３２ｂとを再び導通させることができる。その結果、第１部分３２ａと第２部分３２ｂとを再度導通させるための構成を設けることに起因する装置構成の複雑化を抑制することができる。 Further, in the first embodiment, the pop-out detection unit 32 is displaced due to the elastic deformation of at least one of the first portion 32a and the second portion 32b due to the contact with the pop-out portion Wa. It is configured to detect the protruding portion Wa when the continuity between the portion 32a and the second portion 32b is cut off. With this configuration, since the first portion 32a and the second portion 32b are configured to be displaced due to elastic deformation, the apparatus is different from the case where a configuration for changing the position of a hinge or the like is provided. It is possible to suppress the complexity of the configuration. Further, since the positions of the first portion 32a and the second portion 32b are displaced by the elastic deformation, the first portion 32a and the second portion 32b can be easily returned to the original positions after the contact with the protruding portion Wa. Therefore, when the inspection is performed again after detecting the protruding portion Wa once, the first portion 32a and the second portion 32b are combined without providing a configuration for returning the first portion 32a and the second portion 32b to their original positions. Can be conducted again. As a result, it is possible to suppress the complexity of the device configuration caused by providing the configuration for reconducting the first portion 32a and the second portion 32b.
　また、第１実施形態では、第１部分３２ａおよび第２部分３２ｂは、板状の導体の端部がさらに折り曲げられて互いに面接触する平面の接触面３２Ｎを有し、飛び出し検知部３２は、第１部分３２ａと第２部分３２ｂとのそれぞれの接触面３２Ｎ同士が面接触することによって、第１部分３２ａと第２部分３２ｂとが導通するように構成されている。このように構成すれば、面接触によって導通させることによって、より確実に第１部分３２ａと第２部分３２ｂとを電気的に導通させることができる。そのため、第１部分３２ａと第２部分３２ｂとの導通が不安定になることを抑制することができるので、飛び出し検知部３２による飛び出し部分Ｗａの検知の精度が低下することを抑制することができる。また、一度飛び出し部分Ｗａを検知した後に再び検査を行うために、第１部分３２ａと第２部分３２ｂとを再度接触させる場合にも、第１部分３２ａと第２部分３２ｂとのそれぞれの接触面３２Ｎ同士を、平面によって面接触させることができる。そのため、第１部分３２ａと第２部分３２ｂとの位置がワイヤロープＷの移動方向へずれている場合にも、第１部分３２ａと第２部分３２ｂとを確実に接触させることができる。 Further, in the first embodiment, the first portion 32a and the second portion 32b have a flat contact surface 32N in which the end portions of the plate-shaped conductors are further bent and come into surface contact with each other, and the pop-out detection unit 32 has a pop-out detection unit 32. The contact surfaces 32N of the first portion 32a and the second portion 32b are brought into surface contact with each other so that the first portion 32a and the second portion 32b are electrically connected to each other. With this configuration, the first portion 32a and the second portion 32b can be more reliably electrically conducted by conducting the conduction by surface contact. Therefore, it is possible to prevent the continuity between the first portion 32a and the second portion 32b from becoming unstable, and thus it is possible to prevent the pop-out detection unit 32 from deteriorating the detection accuracy of the pop-out portion Wa. .. Further, even when the first portion 32a and the second portion 32b are brought into contact with each other again in order to perform the inspection again after detecting the protruding portion Wa once, the contact surfaces of the first portion 32a and the second portion 32b, respectively. The 32Ns can be brought into surface contact with each other by a flat surface. Therefore, even when the positions of the first portion 32a and the second portion 32b are displaced in the moving direction of the wire rope W, the first portion 32a and the second portion 32b can be reliably brought into contact with each other.
　また、第１実施形態では、飛び出し検知部３２は、検知コイル３１によってワイヤロープＷの磁束の検知を行う場合に、ワイヤロープＷからの離間距離である検知部離間距離Ｄ２が検知コイル３１とワイヤロープＷとの離間距離であるコイル離間距離Ｄ１以下の大きさとなるように配置され、検知コイル３１による検知を行わない場合に、検知部離間距離Ｄ２が検査運転時よりも大きくなるように配置される。このように構成すれば、ワイヤロープＷの磁束の検知を精度よく行うために検知コイル３１をワイヤロープＷに近づけて配置する場合にも、検知コイル３１よりもさらにワイヤロープＷの近くに配置されている飛び出し検知部３２によって、検知コイル３１と接触する可能性のある飛び出し部分Ｗａを精度よく検知することができる。その結果、検知コイル３１をワイヤロープＷに近づけて磁束を検知する場合にも、検知コイル３１と飛び出し部分Ｗａとの接触を精度よく抑制することができる。また、第１実施形態では、検知コイル３１による検知を行わない場合には、飛び出し検知部３２をワイヤロープＷから離間した位置に配置するため、検知を行わない場合にワイヤロープＷの移動速度を大きくすることによってワイヤロープＷの振動幅が増加した場合にも、飛び出し検知部３２とワイヤロープＷとの接触を抑制することができる。そのため、検知コイル３１による検知を行わない場合に、ワイヤロープＷの動作速度を大きくすることによって、飛び出し検知部３２との接触を回避しながら効率よくワイヤロープＷを移動（駆動）させることができる。 Further, in the first embodiment, when the pop-out detection unit 32 detects the magnetic flux of the wire rope W by the detection coil 31, the detection unit separation distance D2, which is the separation distance from the wire rope W, is the detection coil 31 and the wire. It is arranged so as to have a size equal to or less than the coil separation distance D1 which is the separation distance from the rope W, and the detection unit separation distance D2 is arranged to be larger than that during the inspection operation when the detection coil 31 does not perform detection. Rope. With this configuration, even when the detection coil 31 is arranged closer to the wire rope W in order to accurately detect the magnetic flux of the wire rope W, it is arranged closer to the wire rope W than the detection coil 31. The pop-out detection unit 32 can accurately detect the pop-out portion Wa that may come into contact with the detection coil 31. As a result, even when the detection coil 31 is brought close to the wire rope W to detect the magnetic flux, the contact between the detection coil 31 and the protruding portion Wa can be accurately suppressed. Further, in the first embodiment, when the detection by the detection coil 31 is not performed, the pop-out detection unit 32 is arranged at a position away from the wire rope W. Therefore, when the detection is not performed, the moving speed of the wire rope W is increased. Even when the vibration width of the wire rope W is increased by increasing the size, it is possible to suppress the contact between the pop-out detection unit 32 and the wire rope W. Therefore, when the detection coil 31 does not perform detection, the wire rope W can be efficiently moved (driven) while avoiding contact with the pop-out detection unit 32 by increasing the operating speed of the wire rope W. ..
　また、第１実施形態では、検知コイル３１は、ワイヤロープＷが延びる方向と直交する方向に配置されている第１検知コイル３１ａと、ワイヤロープＷに対して第１検知コイル３１ａが配置される側とは反対側において第１検知コイル３１ａとともにワイヤロープＷを取り囲むように配置されている第２検知コイル３１ｂとを含み、駆動部４０は、飛び出し検知部３２からの検知信号に基づいて、第１検知コイル３１ａおよび第２検知コイル３１ｂの各々を、ワイヤロープＷから離間する方向に移動させるように構成されている。このように構成すれば、検知コイル３１が第１検知コイル３１ａと第２検知コイル３１ｂとの２つに分割されて構成されているので、飛び出し部分Ｗａが検知された場合に、ワイヤロープＷの２つの方向のそれぞれに検知コイル３１を容易に移動（退避）させることができる。そのため、検知コイル３１を、１つの部材によってワイヤロープＷを取り囲むように構成する場合に比べて、検知コイル３１と飛び出し部分Ｗａとの接触をより容易に抑制することができる。 Further, in the first embodiment, the detection coil 31 is arranged with the first detection coil 31a arranged in a direction orthogonal to the direction in which the wire rope W extends, and the first detection coil 31a with respect to the wire rope W. The drive unit 40 includes a second detection coil 31b arranged so as to surround the wire rope W together with the first detection coil 31a on the side opposite to the side, and the drive unit 40 is the first based on the detection signal from the pop-out detection unit 32. Each of the 1st detection coil 31a and the 2nd detection coil 31b is configured to move in a direction away from the wire rope W. With this configuration, the detection coil 31 is divided into two parts, a first detection coil 31a and a second detection coil 31b. Therefore, when the protruding portion Wa is detected, the wire rope W The detection coil 31 can be easily moved (retracted) in each of the two directions. Therefore, the contact between the detection coil 31 and the protruding portion Wa can be more easily suppressed as compared with the case where the detection coil 31 is configured to surround the wire rope W by one member.
　また、第１実施形態では、ワイヤロープＷに対して予め磁界を印加しワイヤロープＷの磁化の方向を整える磁界印加部２０をさらに備え、第１検知コイル３１ａおよび第２検知コイル３１ｂは、磁界印加部２０により予め磁界が印加された後に、ワイヤロープＷの磁束を検知するように構成されているとともに、ワイヤロープＷの延びる方向に沿って巻回するように設けられており、駆動部４０は、飛び出し検知部３２からの検知信号に基づいて、ワイヤロープＷの延びる方向に沿って巻回するように設けられた第１検知コイル３１ａおよび第２検知コイル３１ｂの各々を、ワイヤロープＷから離間する方向に移動させるように構成されている。このように構成すれば、ワイヤロープＷを取り囲むように第１検知コイル３１ａおよび第２検知コイル３１ｂを配置することによって、ワイヤロープＷの内部も含めた全体の磁束の測定を行う全磁束法によってワイヤロープＷの検査を行う場合にも、飛び出し部分Ｗａが検知された場合に第１検知コイル３１ａおよび第２検知コイル３１ｂを移動させることができる。そのため、全磁束法によって、ワイヤロープＷの内部の異常などを検知する場合にも、第１検知コイル３１ａおよび第２検知コイル３１ｂと飛び出し部分Ｗａとの接触を効果的に抑制することができる。 Further, in the first embodiment, a magnetic field application unit 20 for applying a magnetic field to the wire rope W in advance to adjust the direction of magnetization of the wire rope W is further provided, and the first detection coil 31a and the second detection coil 31b are provided with a magnetic field. The drive unit 40 is configured to detect the magnetic flux of the wire rope W after the magnetic field is applied in advance by the application unit 20, and is provided to wind the wire rope W along the extending direction of the wire rope W. Refers to each of the first detection coil 31a and the second detection coil 31b provided so as to be wound along the extending direction of the wire rope W based on the detection signal from the pop-out detection unit 32 from the wire rope W. It is configured to move in the direction of separation. With this configuration, by arranging the first detection coil 31a and the second detection coil 31b so as to surround the wire rope W, the total magnetic flux method for measuring the entire magnetic flux including the inside of the wire rope W can be used. Even when the wire rope W is inspected, the first detection coil 31a and the second detection coil 31b can be moved when the protruding portion Wa is detected. Therefore, even when an abnormality inside the wire rope W is detected by the total magnetic flux method, the contact between the first detection coil 31a and the second detection coil 31b and the protruding portion Wa can be effectively suppressed.
　また、第１実施形態では、飛び出し検知部３２によってワイヤロープＷの外表面からの飛び出し部分Ｗａが検知されたことを示す情報を装置外部に出力する通信部５５を、さらに備える。このように構成すれば、飛び出し検知部３２によって飛び出し部分Ｗａが検知された場合に、ワイヤロープ検査装置１０１と接続されている、処理装置１０２（ＰＣ）およびエレベータ１０３の制御装置１０３ｄなどに、飛び出し部分Ｗａが検知されたことを示す情報を出力することができる。そのため、飛び出し部分Ｗａが検知された場合に、飛び出し部分Ｗａの検知を検査作業者に報知すること、および、エレベータ１０３の動作を停止させることなどの処理を、ワイヤロープ検査装置１０１の外部の装置によって行わせることができる。その結果、飛び出し検知部３２によってワイヤロープＷの外表面からの飛び出し部分Ｗａが検知された場合に、ワイヤロープ検査装置１０１の外部の装置と連携することによって、検査作業者によるワイヤロープＷの交換作業を効率よく行うことができる。 Further, in the first embodiment, the communication unit 55 is further provided to output information indicating that the protrusion portion Wa from the outer surface of the wire rope W has been detected by the protrusion detection unit 32 to the outside of the device. With this configuration, when the pop-out portion Wa is detected by the pop-out detection unit 32, it pops out to the processing device 102 (PC) connected to the wire rope inspection device 101, the control device 103d of the elevator 103, and the like. Information indicating that the partial Wa has been detected can be output. Therefore, when the protruding portion Wa is detected, processing such as notifying the inspection worker of the detection of the protruding portion Wa and stopping the operation of the elevator 103 is performed by an external device of the wire rope inspection device 101. Can be done by. As a result, when the protruding portion Wa from the outer surface of the wire rope W is detected by the pop-out detection unit 32, the wire rope W is replaced by the inspection worker by cooperating with an external device of the wire rope inspection device 101. Work can be done efficiently.
　また、第１実施形態では、検知コイル３１は、エレベータ１０３に設けられたワイヤロープＷの磁束を検知するように構成されており、駆動部４０は、エレベータ１０３の通常運転時には、検知コイル３１とワイヤロープＷとの距離であるコイル離間距離Ｄ１を大きくするように構成されており、通常運転時よりも運転速度の小さい検査運転時には、コイル離間距離Ｄ１を通常運転時よりも小さくするように検知コイル３１を移動させるとともに、飛び出し検知部３２からの検知信号に基づいて、飛び出し部分Ｗａが検知された場合にはコイル離間距離Ｄ１を大きくするように構成されている。このように構成すれば、エレベータ１０３の通常運転時では、運転速度が大きいためにワイヤロープＷの振動の幅が大きくなるので、コイル離間距離Ｄ１を大きくすることによって検知コイル３１がワイヤロープＷと接触することを抑制することができる。そして、エレベータ１０３の検査運転時では、通常運転時に比べて運転速度が小さいためにワイヤロープＷの振動の幅が小さくなるので、コイル離間距離Ｄ１を小さくすることによって検知コイル３１の検知精度を向上させることができる。また、コイル離間距離Ｄ１を小さくして検査運転を行っている場合にも、飛び出し検知部３２からの検知信号に基づいてコイル離間距離Ｄ１を大きくすることによって、検知コイル３１と飛び出し部分Ｗａとの接触を回避することができる。その結果、エレベータ１０３の運転動作に対応するようにコイル離間距離Ｄ１を変更させることによって、通常運転時と検査運転時との両方において、ワイヤロープＷおよび飛び出し部分Ｗａと検知コイル３１との接触を回避しながら、検査運転時において、精度よくワイヤロープＷの磁束を検知することができる。 Further, in the first embodiment, the detection coil 31 is configured to detect the magnetic flux of the wire rope W provided in the elevator 103, and the drive unit 40 together with the detection coil 31 during normal operation of the elevator 103. It is configured to increase the coil separation distance D1, which is the distance from the wire rope W, and detects that the coil separation distance D1 is smaller than during normal operation during inspection operation, which has a lower operating speed than during normal operation. The coil 31 is moved, and when the pop-out portion Wa is detected based on the detection signal from the pop-out detection unit 32, the coil separation distance D1 is increased. With this configuration, during normal operation of the elevator 103, the width of vibration of the wire rope W becomes large due to the high operating speed. Therefore, by increasing the coil separation distance D1, the detection coil 31 becomes the wire rope W. Contact can be suppressed. During the inspection operation of the elevator 103, the vibration width of the wire rope W becomes smaller because the operating speed is smaller than that during the normal operation. Therefore, the detection accuracy of the detection coil 31 is improved by reducing the coil separation distance D1. Can be made to. Further, even when the inspection operation is performed by reducing the coil separation distance D1, by increasing the coil separation distance D1 based on the detection signal from the protrusion detection unit 32, the detection coil 31 and the protrusion portion Wa can be separated from each other. Contact can be avoided. As a result, by changing the coil separation distance D1 so as to correspond to the operation operation of the elevator 103, the contact between the wire rope W and the protruding portion Wa and the detection coil 31 is established both during the normal operation and the inspection operation. While avoiding it, the magnetic flux of the wire rope W can be detected accurately during the inspection operation.
　また、第１実施形態では、検知コイル３１と飛び出し検知部３２とを一体的に接続する接続部３３ａを含む検知本体部３３（検知コイル本体部）をさらに備え、駆動部４０は、飛び出し検知部３２からの検知信号に基づいて、検知本体部３３を移動させることによって、接続部３３ａによって接続された検知コイル３１と飛び出し検知部３２とを一体的に移動させるように構成されている。このように構成すれば、共通の駆動部４０によって、一体的に検知コイル３１と飛び出し検知部３２とを移動させることができるので、検知コイル３１と飛び出し検知部３２との各々に駆動部４０を設ける場合と異なり、装置構成の複雑化を抑制することができる。 Further, in the first embodiment, the detection main body 33 (detection coil main body) including the connection portion 33a for integrally connecting the detection coil 31 and the pop-out detection unit 32 is further provided, and the drive unit 40 is the pop-out detection unit. By moving the detection main body 33 based on the detection signal from 32, the detection coil 31 connected by the connection 33a and the pop-out detection unit 32 are configured to be integrally moved. With this configuration, the detection coil 31 and the pop-out detection unit 32 can be integrally moved by the common drive unit 40. Therefore, the drive unit 40 is provided for each of the detection coil 31 and the pop-out detection unit 32. Unlike the case of providing the device, the complexity of the device configuration can be suppressed.
　また、第１実施形態では、ワイヤロープＷは、複数のワイヤロープＷを含み、検知コイル３１は、複数のワイヤロープＷの各々に設けられており、飛び出し検知部３２は、複数のワイヤロープＷの各々の飛び出し部分Ｗａを共通して検知するように構成されており、駆動部４０は、複数のワイヤロープＷのうちの少なくとも１つのワイヤロープＷの外表面からの飛び出し部分Ｗａが検知されたことによる飛び出し検知部３２からの検知信号に基づいて、複数のワイヤロープＷの各々に設けられた検知コイル３１の全てを一体的にワイヤロープＷから離間する方向に移動させるように構成されている。このように構成すれば、複数のワイヤロープＷの磁束の検知を行う場合にも、複数のワイヤロープＷの飛び出し部分Ｗａを共通の飛び出し検知部３２によって検知することができる。そのため、複数のワイヤロープＷの飛び出し部分Ｗａを、それぞれ別個の飛び出し検知部３２によって検知する場合に比べて、装置構成の複雑化を抑制することができる。 Further, in the first embodiment, the wire rope W includes a plurality of wire ropes W, the detection coil 31 is provided for each of the plurality of wire ropes W, and the pop-out detection unit 32 includes the plurality of wire ropes W. The drive unit 40 is configured to detect each of the protruding portions Wa in common, and the driving unit 40 detects the protruding portion Wa from the outer surface of at least one of the plurality of wire ropes W. Based on the detection signal from the pop-out detection unit 32, all of the detection coils 31 provided in each of the plurality of wire ropes W are integrally moved in a direction away from the wire rope W. .. With this configuration, even when the magnetic fluxes of the plurality of wire ropes W are detected, the protrusion portion Wa of the plurality of wire ropes W can be detected by the common protrusion detection unit 32. Therefore, it is possible to suppress the complexity of the device configuration as compared with the case where the protruding portion Wa of the plurality of wire ropes W is detected by the separate pop-out detecting units 32.

　図１５～図１７を参照して、第２実施形態によるワイヤロープ検査システム２００の構成について説明する。この第２実施形態は、接続部３３ａによって接続された検知コイル３１および飛び出し検知部３２を一体的に移動するように構成した第１実施形態とは異なり、検知コイル２３１と飛び出し検知部２３２とが別体に構成されている。なお、図中において、上記第１実施形態と同様の構成の部分には、同一の符号を付して図示するとともに説明を省略する。 [Second Embodiment]

In the drawings, the same components as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
　（第２実施形態によるワイヤロープ検査システムの構成）
　図１５に示すように、第２実施形態によるワイヤロープ検査システム２００は、ワイヤロープ検査装置２０１を備える。ワイヤロープ検査装置２０１は、第１実施形態と同様に、エレベータ１０３に設けられたワイヤロープＷの磁束の測定を行い、測定された磁束信号を処理装置１０２に出力する。また、ワイヤロープ検査装置２０１は、検知部２３０と、駆動部２４０とを備える。 (Structure of wire rope inspection system according to the second embodiment)
As shown in FIG. 15, the wire rope inspection system 200 according to the second embodiment includes a wire rope inspection device 201. Similar to the first embodiment, the wire rope inspection device 201 measures the magnetic flux of the wire rope W provided in the elevator 103, and outputs the measured magnetic flux signal to the processing device 102. Further, the wire rope inspection device 201 includes a detection unit 230 and a drive unit 240.
　検知部２３０は、検知コイル２３１、飛び出し検知部２３２、検知コイル本体部２３３ａ、および、飛び出し検知本体部２３３ｂを含む。検知コイル２３１は、第１実施形態と同様にワイヤロープＷの磁束を測定する。すなわち、複数（４本）のワイヤロープＷの各々に対して、Ｚ１方向側とＺ２方向側とに２つずつの検知コイル２３１（第１検知コイル２３１ａおよび第２検知コイル２３１ｂ、図１６参照）が設けられており、ワイヤロープＷの各々を２つの検知コイル２３１（第１検知コイル２３１ａおよび第２検知コイル２３１ｂ）によって取り囲むように構成されている。また、飛び出し検知部２３２は、第１実施形態と同様にワイヤロープＷの外表面の少なくとも一部からの飛び出し部分Ｗａを検知する。 The detection unit 230 includes a detection coil 231, a pop-out detection unit 232, a detection coil main body 233a, and a pop-out detection main body 233b. The detection coil 231 measures the magnetic flux of the wire rope W as in the first embodiment. That is, for each of the plurality (4) wire ropes W, two detection coils 231 on the Z1 direction side and two on the Z2 direction side (first detection coil 231a and second detection coil 231b, see FIG. 16). Is provided, and each of the wire ropes W is configured to be surrounded by two detection coils 231 (first detection coil 231a and second detection coil 231b). Further, the pop-out detection unit 232 detects the pop-out portion Wa from at least a part of the outer surface of the wire rope W as in the first embodiment.
　図１６に示すように、第２実施形態では、検知コイル２３１は、検知コイル本体部２３３ａに配置される。そして、飛び出し検知部２３２は、飛び出し検知本体部２３３ｂに配置される。すなわち、第２実施形態では、飛び出し検知部２３２は、検知コイル２３１とは別体に構成されている。 As shown in FIG. 16, in the second embodiment, the detection coil 231 is arranged in the detection coil main body 233a. Then, the pop-out detection unit 232 is arranged in the pop-out detection main body unit 233b. That is, in the second embodiment, the pop-out detection unit 232 is configured separately from the detection coil 231.
　第２実施形態では、駆動部２４０は、飛び出し検知部２３２からの検知信号に基づいて、検知コイル２３１と飛び出し検知部２３２との各々を移動させるように構成されている。具体的には、駆動部２４０は、検知信号に基づいて、検知コイル２３１と飛び出し検知部２３２との各々を、ワイヤロープＷから離間する方向（Ｚ１方向およびＺ２方向）に分割するように移動させる。また、駆動部２４０は、第１実施形態と同様に、エレベータ１０３の通常運転時と、検査運転時との各々において、検知コイル２３１と飛び出し検知部２３２との位置を変更させる。 In the second embodiment, the drive unit 240 is configured to move each of the detection coil 231 and the pop-out detection unit 232 based on the detection signal from the pop-out detection unit 232. Specifically, the drive unit 240 moves the detection coil 231 and the pop-out detection unit 232 so as to be separated from the wire rope W in the directions (Z1 direction and Z2 direction) based on the detection signal. .. Further, the drive unit 240 changes the positions of the detection coil 231 and the pop-out detection unit 232 in each of the normal operation and the inspection operation of the elevator 103, as in the first embodiment.
　図１６および図１７に示すように、駆動部２４０は、モータ２４１、プーリ２４２ａ、プーリ２４２ｂ、プーリ２４３ａ、プーリ２４３ｂ、ベルト２４４ａ、ベルト２４４ｂ、軸２４６を含む。駆動部２４０は、共通のモータ２４１の動力を、軸２４６を介してプーリ２４２ａおよび２４２ｂに伝達することによって、別体として構成されている検知コイル２３１および飛び出し検知部２３２を移動させる。 As shown in FIGS. 16 and 17, the drive unit 240 includes a motor 241 and a pulley 242a, a pulley 242b, a pulley 243a, a pulley 243b, a belt 244a, a belt 244b, and a shaft 246. The drive unit 240 moves the detection coil 231 and the pop-out detection unit 232, which are configured as separate bodies, by transmitting the power of the common motor 241 to the pulleys 242a and 242b via the shaft 246.
　具体的には、図１６に示すように、駆動部２４０は、モータ２４１の回転駆動によって、軸２４６を介して検知コイル２３１側（検知コイル本体部２３３ａ側）のプーリ２４２ａを回転させる。そして、プーリ２４２ａが回転することによって、プーリ２４２ａとプーリ２４３ａとの間に張られているベルト２４４ａが移動する。ベルト２４４ａは、検知コイル本体部２３３ａに固定されている。したがって、検知コイル本体部２３３ａが駆動部２４０によって移動させられることによって、検知コイル２３１が、Ｚ１方向およびＺ２方向に移動する。 Specifically, as shown in FIG. 16, the drive unit 240 rotates the pulley 242a on the detection coil 231 side (detection coil main body unit 233a side) via the shaft 246 by rotationally driving the motor 241. Then, as the pulley 242a rotates, the belt 244a stretched between the pulley 242a and the pulley 243a moves. The belt 244a is fixed to the detection coil main body 233a. Therefore, the detection coil main body 233a is moved by the drive unit 240, so that the detection coil 231 moves in the Z1 direction and the Z2 direction.
　また、図１７に示すように、検知コイル２３１を移動させるためのモータ２４１からの動力によって、飛び出し検知部２３２も同様に移動させられる。具体的には、モータ２４１から延びる軸２４６が、飛び出し検知部２３２側（飛び出し検知本体部２３３ｂ側）のプーリ２４２ｂを回転させる。そして、検知コイル２３１側と同様に、プーリ２４２ｂの回転によって、プーリ２４２ｂと２４３ｂとの間に張られているベルト２４４ｂが移動する。ベルト２４４ｂは、飛び出し検知本体部２３３ｂに固定されている。したがって、飛び出し検知本体部２３３ｂが駆動部２４０によって移動させられることによって、飛び出し検知部２３２が、Ｚ１方向およびＺ２方向に移動する。 Further, as shown in FIG. 17, the pop-out detection unit 232 is also moved by the power from the motor 241 for moving the detection coil 231. Specifically, the shaft 246 extending from the motor 241 rotates the pulley 242b on the pop-out detection unit 232 side (pop-out detection main body portion 233b side). Then, similarly to the detection coil 231 side, the belt 244b stretched between the pulleys 242b and 243b moves due to the rotation of the pulley 242b. The belt 244b is fixed to the pop-out detection main body 233b. Therefore, the pop-out detection main body unit 233b is moved by the drive unit 240, so that the pop-out detection unit 232 moves in the Z1 direction and the Z2 direction.
　このように、第２実施形態では、駆動部２４０は、軸２４６を介してモータ２４１の動力を伝達することによって、検知コイル２３１側の検知コイル本体部２３３ａと、飛び出し検知部２３２側の飛び出し検知本体部２３３ｂとを、移動させる。なお、第２実施形態のその他の構成については、第１実施形態と同様である。 As described above, in the second embodiment, the drive unit 240 transmits the power of the motor 241 via the shaft 246 to detect the protrusion of the detection coil main body 233a on the detection coil 231 side and the protrusion detection unit 232 on the detection coil 231 side. The main body portion 233b is moved. The other configurations of the second embodiment are the same as those of the first embodiment.
　（第２実施形態の効果）
　第２実施形態では、以下のような効果を得ることができる。 (Effect of the second embodiment)
In the second embodiment, the following effects can be obtained.
　第２実施形態では、飛び出し検知部２３２は、検知コイル２３１とは別体に構成されており、駆動部２４０は、飛び出し検知部２３２からの検知信号に基づいて、検知コイル２３１と飛び出し検知部２３２との各々を移動させるように構成されている。ここで、飛び出し検知部２３２を、検知コイル２３１と一体的に構成する場合には、検知部２３０（検知コイル２３１および飛び出し検知部２３２）が配置される筐体（本体部）の剛性に起因して、検知コイル２３１から飛び出し検知部２３２までの距離が比較的大きい場合に飛び出し検知部２３２のワイヤロープＷからの離間距離である検知部離間距離Ｄ２が不安定となる。そのため、飛び出し検知部２３２を、検知コイル２３１と一体的に構成する場合には、検知部２３０が配置される筐体の剛性を考慮して、飛び出し検知部２３２の検知コイル２３１からの距離が制限される。これに対して、第２実施形態では、飛び出し検知部２３２を、検知コイル２３１とは別体に構成する。このように構成すれば、検知コイル２３１と飛び出し検知部２３２とを一体的に構成する場合と異なり、検知コイル２３１と飛び出し検知部２３２とを、ワイヤロープＷに対して別個に配置することができる。そのため、検知コイル２３１と飛び出し検知部２３２との各々において、取り付け剛性を上げることができるので、検知コイル２３１から飛び出し検知部２３２までの距離が比較的大きい場合にも、ワイヤロープＷの振動による接触をより効果的に抑制することができる。 In the second embodiment, the pop-out detection unit 232 is configured separately from the detection coil 231, and the drive unit 240 has the detection coil 231 and the pop-out detection unit 232 based on the detection signal from the pop-out detection unit 232. It is configured to move each of the and. Here, when the pop-out detection unit 232 is integrally configured with the detection coil 231 due to the rigidity of the housing (main body portion) in which the detection unit 230 (detection coil 231 and pop-out detection unit 232) is arranged. Therefore, when the distance from the detection coil 231 to the pop-out detection unit 232 is relatively large, the detection unit separation distance D2, which is the distance between the pop-out detection unit 232 and the wire rope W, becomes unstable. Therefore, when the pop-out detection unit 232 is integrally configured with the detection coil 231, the distance of the pop-out detection unit 232 from the detection coil 231 is limited in consideration of the rigidity of the housing in which the detection unit 230 is arranged. Will be done. On the other hand, in the second embodiment, the pop-out detection unit 232 is configured separately from the detection coil 231. With this configuration, unlike the case where the detection coil 231 and the pop-out detection unit 232 are integrally configured, the detection coil 231 and the pop-out detection unit 232 can be arranged separately with respect to the wire rope W. .. Therefore, since the mounting rigidity can be increased in each of the detection coil 231 and the pop-out detection unit 232, contact due to vibration of the wire rope W even when the distance from the detection coil 231 to the pop-out detection unit 232 is relatively large. Can be suppressed more effectively.
　なお、第２実施形態のその他の効果は、上記第１実施形態と同様である。 The other effects of the second embodiment are the same as those of the first embodiment.
　［第３実施形態］
　図１８～図２０を参照して、第３実施形態によるワイヤロープ検査システム３００の構成について説明する。この第３実施形態は、駆動部４０によって、通常運転時における検知コイル３１の位置と検査運転時における検知コイル３１の位置とを自動で変更するように構成した第１実施形態とは異なり、検査作業者による位置変更レバー３６０に対する操作によって、通常運転時における検知コイル３３１の位置と検査運転時における検知コイル３３１の位置とを手動で変更するように構成されている。なお、図中において、上記第１実施形態と同様の構成の部分には、同一の符号を付して図示するとともに説明を省略する。 [Third Embodiment]

This third embodiment is different from the first embodiment in which the drive unit 40 automatically changes the position of the detection coil 31 during normal operation and the position of the detection coil 31 during inspection operation. The position of the detection coil 331 during normal operation and the position of the detection coil 331 during inspection operation are manually changed by the operation of the position change lever 360 by the operator. In the drawings, the same components as those of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
　（第３実施形態によるワイヤロープ検査システムの構成）
　図１８に示すように、第３実施形態によるワイヤロープ検査システム３００は、ワイヤロープ検査装置３０１を備える。ワイヤロープ検査装置３０１は、第１実施形態と同様に、エレベータ１０３に設けられたワイヤロープＷの磁束の測定を行い、測定された磁束信号を処理装置１０２に出力する。また、ワイヤロープ検査装置３０１は、検知部３３０と、駆動部３４０と、位置変更レバー３６０とを備える。 (Structure of wire rope inspection system according to the third embodiment)
As shown in FIG. 18, the wire rope inspection system 300 according to the third embodiment includes a wire rope inspection device 301.

Further, the wire rope inspection device 301 includes a detection unit 330, a drive unit 340, and a position change lever 360.
　検知部３３０は、検知コイル３３１、飛び出し検知部３３２、および、検知本体部３３３を含む。第１実施形態と同様に、検知コイル３３１は、ワイヤロープＷの磁束を測定する。そして、検知コイル３３１は、検知本体部３３３に配置されている。また、検知コイル３３１は、ワイヤロープＷからの離間距離（コイル離間距離Ｄ１）を変更可能に構成されている。飛び出し検知部３３２は、第１実施形態と同様にワイヤロープＷの外表面の少なくとも一部からの飛び出し部分Ｗａを検知する。 The detection unit 330 includes a detection coil 331, a pop-out detection unit 332, and a detection main body unit 333. Similar to the first embodiment, the detection coil 331 measures the magnetic flux of the wire rope W. The detection coil 331 is arranged in the detection main body 333. Further, the detection coil 331 is configured so that the separation distance from the wire rope W (coil separation distance D1) can be changed. The pop-out detection unit 332 detects the pop-out portion Wa from at least a part of the outer surface of the wire rope W as in the first embodiment.
　図１９に示すように、検知コイル３３１は、第１実施形態と同様に、Ｚ１方向側に配置されている第１検知コイル３３１ａと、Ｚ２方向側に配置されている第２検知コイル３３１ｂとを含む。そして、検知コイル３３１（第１検知コイル３３１ａおよび第２検知コイル３３１ｂ）は、それぞれＺ１方向およびＺ２方向に移動可能に構成されている。 As shown in FIG. 19, the detection coil 331 includes a first detection coil 331a arranged on the Z1 direction side and a second detection coil 331b arranged on the Z2 direction side, as in the first embodiment. include. The detection coil 331 (first detection coil 331a and second detection coil 331b) is configured to be movable in the Z1 direction and the Z2 direction, respectively.
　図１９および図２０に示すように、位置変更レバー３６０は、検知コイル３３１の位置を変更させる操作を受け付ける。ここで、第３実施形態におけるワイヤロープ検査装置３０１は、第１実施形態と同様に、エレベータ１０３の通常運転時と検査運転時とにおいて、検知コイル３３１の位置を異ならせた状態で運転を行うように構成されている。第３実施形態では、位置変更レバー３６０は、検知コイル３３１とワイヤロープＷとの距離であるコイル離間距離Ｄ１が大きい通常運転位置と、通常運転位置よりもコイル離間距離Ｄ１が小さい検査運転位置とのいずれかに、検知コイル３３１の位置を変更するために操作される。言い換えると、第３実施形態におけるワイヤロープ検査装置３０１は、検査作業者による位置変更レバー３６０に対する操作によって、検知コイル３３１の位置を、通常運転位置と検査運転位置とのいずれかに変更可能に構成されている。 As shown in FIGS. 19 and 20, the position change lever 360 accepts an operation of changing the position of the detection coil 331. Here, the wire rope inspection device 301 in the third embodiment operates in a state where the position of the detection coil 331 is different between the normal operation and the inspection operation of the elevator 103, as in the first embodiment. It is configured as follows. In the third embodiment, the position change lever 360 has a normal operation position in which the coil separation distance D1 which is the distance between the detection coil 331 and the wire rope W is large, and an inspection operation position in which the coil separation distance D1 is smaller than the normal operation position. Is operated to change the position of the detection coil 331. In other words, the wire rope inspection device 301 according to the third embodiment is configured so that the position of the detection coil 331 can be changed to either the normal operation position or the inspection operation position by the operation of the inspection operator with respect to the position change lever 360. Has been done.
　たとえば、検知コイル３３１が通常運転位置に配置されている状態から、位置変更レバー３６０が操作されることによって、検知コイル３３１が、検査運転位置へと配置される。そして、検知コイル３３１が検査運転位置に配置された状態で、検知コイル３３１によってワイヤロープＷの磁束が検知（測定）される。 For example, the detection coil 331 is arranged at the inspection operation position by operating the position change lever 360 from the state where the detection coil 331 is arranged at the normal operation position. Then, the magnetic flux of the wire rope W is detected (measured) by the detection coil 331 in a state where the detection coil 331 is arranged at the inspection operation position.
　位置変更レバー３６０は、把持部３６１と、付勢部材３６２と、支点３６３と、ピン３６４とを含む。把持部３６１は、位置変更レバー３６０による検知コイル３３１の位置変更を行うために検査作業者に把持される部分である。支点３６３は、位置変更レバー３６０の回動移動の支点（中心点）となる。付勢部材３６２は、たとえば、ステンレスのバネである。付勢部材３６２は、一端が支点３６３よりも片方側（Ｙ１方向側）の位置変更レバー３６０に固定され、他端が支点３６３よりも他方側（Ｙ２方向側）の第２検知コイル３３１ｂ側（Ｚ２方向側）の検知本体部３３３に固定されている。付勢部材３６２は、位置変更レバー３６０側と検知本体部３３３側とを互いに引き合う方向に付勢することによって、通常運転位置と検査運転位置との各々の状態（検知コイル３３１の位置）を保持する。すなわち、付勢部材３６２は、位置変更レバー３６０の把持部３６１がＺ１方向側に傾いた状態と、Ｚ２方向側に傾いた状態との各々の状態を保持する。また、ピン３６４は、第２検知コイル３３１ｂ側（Ｚ２方向側）の検知本体部３３３に設けられたＹ方向に延びる長孔に挿入される。位置変更レバー３６０は、第２検知コイル３３１ｂ側（Ｚ２方向側）の検知本体部３３３に設けられた長孔にピン３６４がＹ方向に移動可能に挿入されることによって、第２検知コイル３３１ｂ側の検知本体部３３３に接続されている。 The position change lever 360 includes a grip portion 361, an urging member 362, a fulcrum 363, and a pin 364. The grip portion 361 is a portion gripped by an inspection worker in order to change the position of the detection coil 331 by the position change lever 360. The fulcrum 363 serves as a fulcrum (center point) for the rotational movement of the position change lever 360. The urging member 362 is, for example, a stainless steel spring. One end of the urging member 362 is fixed to the position change lever 360 on one side (Y1 direction side) of the fulcrum 363, and the other end is on the second detection coil 331b side (Y2 direction side) of the other side (Y2 direction side) of the fulcrum 363. It is fixed to the detection main body 333 (Z2 direction side). The urging member 362 holds each state (position of the detection coil 331) of the normal operation position and the inspection operation position by urging the position change lever 360 side and the detection main body 333 side in a direction of attracting each other. do. That is, the urging member 362 holds a state in which the grip portion 361 of the position change lever 360 is tilted toward the Z1 direction and a state in which the grip portion 361 is tilted toward the Z2 direction. Further, the pin 364 is inserted into an elongated hole extending in the Y direction provided in the detection main body portion 333 on the second detection coil 331b side (Z2 direction side). The position change lever 360 is on the second detection coil 331b side by inserting the pin 364 into a long hole provided in the detection main body 333 on the second detection coil 331b side (Z2 direction side) so that the pin 364 can move in the Y direction. It is connected to the detection main body 333 of.
　なお、第１検知コイル３３１ａ側（Ｚ１方向側）の検知本体部３３３と、第２検知コイル３３１ｂ側（Ｚ２方向側）の検知本体部３３３は、後述する駆動部３４０のベルト３４４によって連動して移動するように構成されている。したがって、位置変更レバー３６０は、第２検知コイル３３１ｂ側（Ｚ２方向側）の検知本体部３３３を移動させることによって、第１検知コイル３３１ａおよび第２検知コイル３３１ｂの両方の位置を連動させて変更可能に構成されている。 The detection main body 333 on the first detection coil 331a side (Z1 direction side) and the detection main body 333 on the second detection coil 331b side (Z2 direction side) are interlocked by the belt 344 of the drive unit 340 described later. It is configured to move. Therefore, the position change lever 360 changes the positions of both the first detection coil 331a and the second detection coil 331b in conjunction with each other by moving the detection main body portion 333 on the second detection coil 331b side (Z2 direction side). It is configured to be possible.
　駆動部３４０は、第１実施形態と同様に、飛び出し検知部３３２からの検知信号に基づいて、検知コイル３３１をワイヤロープＷから離間する方向（Ｚ１方向およびＺ２方向）に移動（退避）させる。すなわち、第３実施形態では、駆動部３４０は、位置変更レバー３６０に対する操作によって、検知コイル３３１の位置が通常運転位置から検査運転位置に移動させられた状態で、飛び出し検知部３３２からの検知信号に基づいて、検知コイル３３１の位置を検査運転位置から通常運転位置に変更させることによって、検知コイル３３１をワイヤロープＷから離間する方向に移動させるように構成されている。 Similar to the first embodiment, the drive unit 340 moves (retracts) the detection coil 331 in the direction away from the wire rope W (Z1 direction and Z2 direction) based on the detection signal from the pop-out detection unit 332. That is, in the third embodiment, the drive unit 340 has the detection signal from the pop-out detection unit 332 in a state where the position of the detection coil 331 is moved from the normal operation position to the inspection operation position by the operation with respect to the position change lever 360. The detection coil 331 is configured to move in a direction away from the wire rope W by changing the position of the detection coil 331 from the inspection operation position to the normal operation position.
　駆動部３４０は、ソレノイドコイル３４１、プーリ３４２、プーリ３４３、および、ベルト３４４を含む。ベルト３４４は、プーリ３４２およびプーリ３４３の間に張られている。また、ベルト３４４は、検知本体部３３３に固定されている。すなわち、第１検知コイル３３１ａが配置されている検知本体部３３３と、第２検知コイル３３１ｂが配置されている検知本体部３３３とが、ベルト３４４によって連動してＺ方向に移動する。すなわち、ベルト３４４に固定された検知本体部３３３が連動して移動することによって、第１検知コイル３３１ａおよび第２検知コイル３３１ｂが、互いに離間する方向に移動する。 The drive unit 340 includes a solenoid coil 341, a pulley 342, a pulley 343, and a belt 344. The belt 344 is stretched between the pulley 342 and the pulley 343. Further, the belt 344 is fixed to the detection main body 333. That is, the detection main body 333 in which the first detection coil 331a is arranged and the detection main body 333 in which the second detection coil 331b is arranged move in the Z direction in conjunction with each other by the belt 344. That is, the detection main body 333 fixed to the belt 344 moves in conjunction with each other, so that the first detection coil 331a and the second detection coil 331b move in a direction away from each other.
　図２０に示すように、ソレノイドコイル３４１は、接続棒３４１ａを介して位置変更レバー３６０に接続されている。また、ソレノイドコイル３４１は、図示しない電源回路からの電流によって磁界を発生させて、接続棒３４１ａをＺ１方向に移動させて位置変更レバー３６０を回動させる。すなわち、ソレノイドコイル３４１は、飛び出し検知部３３２からの検知信号に基づいて、位置変更レバー３６０の位置（角度）を変更（回動）させることによって、検知コイル３３１（第１検知コイル３３１ａおよび第２検知コイル３３１ｂ）をワイヤロープＷから離間する方向（Ｚ１方向およびＺ２方向）に移動させるように構成されている。 As shown in FIG. 20, the solenoid coil 341 is connected to the position change lever 360 via the connecting rod 341a. Further, the solenoid coil 341 generates a magnetic field by a current from a power supply circuit (not shown), moves the connection rod 341a in the Z1 direction, and rotates the position change lever 360. That is, the solenoid coil 341 changes (rotates) the position (angle) of the position change lever 360 based on the detection signal from the pop-out detection unit 332, thereby changing (rotating) the detection coil 331 (first detection coil 331a and second detection coil 331a). The detection coil 331b) is configured to move in the direction away from the wire rope W (Z1 direction and Z2 direction).
　なお、飛び出し検知部３３２は、検知コイル３３１と同様に、位置変更レバーによって、位置を変更するように構成されていてもよい。また、飛び出し検知部３３２は、第１実施形態のように接続部に接続され検知コイル３３１と一体的に移動するように構成されていてもよい。また、第３実施形態のその他の構成については、第１実施形態と同様である。 Note that the pop-out detection unit 332 may be configured to change the position by the position change lever, similarly to the detection coil 331. Further, the pop-out detection unit 332 may be configured to be connected to the connection unit and move integrally with the detection coil 331 as in the first embodiment. Further, the other configurations of the third embodiment are the same as those of the first embodiment.
　（第３実施形態の効果）
　第３実施形態では、以下のような効果を得ることができる。 (Effect of the third embodiment)
In the third embodiment, the following effects can be obtained.
　第３実施形態では、検知コイル３３１とワイヤロープＷとの距離であるコイル離間距離Ｄ１が大きい通常運転位置と、通常運転位置よりもコイル離間距離Ｄ１が小さい検査運転位置とのいずれかに、検知コイル３３１の位置を変更するために操作される位置変更レバー３６０をさらに備え、駆動部３４０は、位置変更レバー３６０に対する操作によって、検知コイル３３１の位置が通常運転位置から検査運転位置に移動させられた状態で、飛び出し検知部３３２からの検知信号に基づいて、検知コイル３３１の位置を検査運転位置から通常運転位置に変更させることによって、検知コイル３３１をワイヤロープＷから離間する方向に移動させるように構成されている。このように構成すれば、通常運転位置から検査運転位置に検知コイル３３１の位置を変更させてワイヤロープＷの検査を行う場合に、位置変更レバー３６０に対す操作によって、検知コイル３３１の位置を容易に変更させることができる。そのため、駆動部３４０による検知コイル３３１の移動を制御することによって検知コイル３３１の位置を変更させる場合と比べて、通常運転から検査運転への切り替えをより容易に行うことができる。 In the third embodiment, the detection is performed at either the normal operation position where the coil separation distance D1 which is the distance between the detection coil 331 and the wire rope W is large and the inspection operation position where the coil separation distance D1 is smaller than the normal operation position. Further, the position change lever 360 operated to change the position of the coil 331 is further provided, and the drive unit 340 is moved from the normal operation position to the inspection operation position by the operation with respect to the position change lever 360. In this state, the detection coil 331 is moved in the direction away from the wire rope W by changing the position of the detection coil 331 from the inspection operation position to the normal operation position based on the detection signal from the pop-out detection unit 332. It is configured in. With this configuration, when the position of the detection coil 331 is changed from the normal operation position to the inspection operation position to inspect the wire rope W, the position of the detection coil 331 can be easily moved by operating the position change lever 360. Can be changed to. Therefore, it is possible to more easily switch from the normal operation to the inspection operation as compared with the case where the position of the detection coil 331 is changed by controlling the movement of the detection coil 331 by the drive unit 340.
　なお、第３実施形態のその他の効果は、上記第１および第２実施形態と同様である。 The other effects of the third embodiment are the same as those of the first and second embodiments.

　たとえば、上記第１～第３実施形態では、飛び出し検知部３２（２３２、３３２）を、ワイヤロープＷを取り囲むように配置する例を示したが、本発明はこれに限られない。たとえば、平面型の検知コイルを用いる場合には、飛び出し検知部を、平面型の検知コイルの形状に対応するように飛び出し部分Ｗａを検知するように構成してもよい。すなわち、円形の孔部を形成するように切り欠きを設けるのではなく、上下方向の各々より直線状の端部を有する板状の部材によって挟み込むように、飛び出し検知部を構成してもよい。 For example, in the first to third embodiments, the pop-out detection unit 32 (232, 332) is arranged so as to surround the wire rope W, but the present invention is not limited to this. For example, when a flat type detection coil is used, the pop-out detection unit may be configured to detect the pop-out portion Wa so as to correspond to the shape of the flat-type detection coil. That is, instead of providing a notch so as to form a circular hole portion, the pop-out detection portion may be configured so as to be sandwiched by a plate-shaped member having linear ends in each of the vertical directions.
　また、上記第１～第３実施形態では、飛び出し検知部３２（２３２、３３２）を、第１部分３２ａと第２部分３２ｂとの２つの部分によって、ワイヤロープＷを取り囲むように構成する例を示したが、本発明はこれに限られない。たとえば、１つの部分（部材）を巻き付けるように配置することによって飛び出し検知部を構成するようにしてもよい。 Further, in the first to third embodiments, an example in which the pop-out detection unit 32 (232, 332) is configured to surround the wire rope W by two portions, the first portion 32a and the second portion 32b.

Not limited to this. For example, the pop-out detection unit may be configured to detect the pop-out portion Wa without contacting the pop-out portion Wa. For example, the pop-out detection unit may be configured to detect a portion larger than the assumed normal cross-sectional area (width) of the wire rope W as the pop-out portion Wa by using an optical sensor.
　また、上記第１～第３実施形態では、飛び出し検知部３２（２３２、３３２）を、検知コイル３１（２３１、３３１）よりもワイヤロープＷの上流側に配置する例を示したが、本発明はこれに限られない。たとえば、飛び出し検知部を検知コイル３１（２３１、３３１）の上流側と下流側との両方に設けるようにしてもよい。すなわち、片方向のみならず両方向からのワイヤロープＷの移動に対応可能に飛び出し検知部を構成してもよい。その場合には、磁界印加部も同様に、検知コイル３１（２３１、３３１）の上流側と下流側との両方に配置するようにしてもよい。 Further, in the first to third embodiments, the pop-out detection unit 32 (232, 332) is arranged on the upstream side of the wire rope W with respect to the detection coil 31 (231, 331).

That is, the pop-out detection unit may be configured so as to be able to cope with the movement of the wire rope W not only from one direction but also from both directions. In that case, the magnetic field application unit may be similarly arranged on both the upstream side and the downstream side of the detection coil 31 (231, 331).
　また、上記第１～第３実施形態では、飛び出し検知部３２（２３２、３３２）を、導通した状態で配置するとともに、導通が遮断された場合に、飛び出し部分Ｗａを検知する例を示したが、本発明はこれに限られない。たとえば、飛び出し部分Ｗａとの接触に起因して飛び出し検知部が変形（変位）することによって、飛び出し検知部とは別個に配置されている端子と飛び出し検知部が接触して導通した場合に、飛び出し部分Ｗａを検知するように構成してもよい。すなわち、導通が遮断された（ＯＦＦになった）場合ではなく、導通が発生した（ＯＮになった）ことに基づいて、飛び出し部分Ｗａを検知するようにしてもよい。また、飛び出し検知部の第１部分と第２部分との各々を、第１部分と第２部分とは別個に配置されている端子などと接触して導通している状態で配置するとともに、飛び出し部分Ｗａとの接触によって導通が遮断された場合に、飛び出し部分Ｗａを検知するように構成してもよい。また、エンコーダ、または、ポテンショメータなどのセンサによって飛び出し検知部の変位が検知されたことに基づいて、飛び出し検知部と飛び出し部分Ｗａとの接触を検知するように構成してもよい。 Further, in the first to third embodiments, the pop-out detection unit 32 (232, 332) is arranged in a conductive state, and when the continuity is interrupted, the pop-out portion Wa is detected. , The present invention is not limited to this. For example, when the pop-out detection unit is deformed (displaced) due to contact with the pop-out portion Wa, and the terminal arranged separately from the pop-out detection unit and the pop-out detection unit come into contact with each other and become conductive, the pop-out detection unit pops out. It may be configured to detect a partial Wa. That is, the protruding portion Wa may be detected based on the occurrence of continuity (turned on) rather than the case where the continuity is cut off (turned off). In addition, each of the first portion and the second portion of the pop-out detection unit is arranged in a state of being in contact with and conducting a terminal or the like separately arranged from the first portion and the second portion, and pop-out. It may be configured to detect the protruding portion Wa when the continuity is cut off by the contact with the portion Wa. Further, it may be configured to detect the contact between the pop-out detection unit and the pop-out portion Wa based on the fact that the displacement of the pop-out detection unit is detected by a sensor such as an encoder or a potentiometer.

For example, the pop-out detection unit may be configured by a rod-shaped (wire-shaped) conductor.
　また、上記第１～第３実施形態では、飛び出し検知部３２（２３２、３３２）は、飛び出し部分Ｗａとの接触によって弾性変形する例を示したが、本発明はこれに限られない。たとえば、飛び出し検知部を、ヒンジなどの可動部分を設けるとともに、飛び出し部分Ｗａとの接触によって可動部分が動作するように構成してもよい。 Further, in the first to third embodiments, the pop-out detection unit 32 (232, 332) is elastically deformed by contact with the pop-out portion Wa, but the present invention is not limited to this. For example, the pop-out detection unit may be provided with a movable portion such as a hinge, and the movable portion may be configured to operate by contact with the pop-out portion Wa.
　また、上記第１～第３実施形態では、飛び出し検知部３２（２３２、３３２）の第１部分３２ａ（２３２ａ、３３２ａ）および第２部分３２ｂ（２３２ｂ、３３２ｂ）の各々において、板状の導体の端部がさらに折り曲げられた接触面３２Ｎを有する例を示したが、本発明はこれに限られない。たとえば、第１部分と第２部分とを、接触面を有さない端部で接触して導通させるように構成してもよい。また、折り曲げられるのではなく溶接されることによって、接続面が設けられるようにしてもよい。 Further, in the first to third embodiments, the plate-shaped conductor is formed in each of the first portion 32a (232a, 332a) and the second portion 32b (232b, 332b) of the pop-out detection unit 32 (232, 332). Although an example is shown in which the end portion has a contact surface 32N further bent, the present invention is not limited to this.

Further, the connecting surface may be provided by welding instead of being bent.
　また、上記第１～第３実施形態では、飛び出し検知部３２（２３２、３３２）を、検知部離間距離Ｄ２がコイル離間距離Ｄ１以下の大きさとなるように配置される例を示したが、本発明はこれに限られない。たとえば、検知部離間距離Ｄ２がコイル離間距離Ｄ１よりも大きい距離となるように飛び出し検知部を配置してもよい。具体的には、飛び出し検知部を、接触せずに飛び出し部分Ｗａを検知するように構成する場合には、検知部離間距離Ｄ２をコイル離間距離Ｄ１よりも大きくして飛び出し部分Ｗａを検知するようにしてもよい。 Further, in the first to third embodiments, the pop-out detection unit 32 (232, 332) is arranged so that the detection unit separation distance D2 is equal to or less than the coil separation distance D1.
