Description

管構件的檢查系統及管構件的檢查方法Inspection system for tubular components and inspection method for tubular components

本發明,關於管構件的檢查系統及管構件的檢查方法。The present invention relates to a pipe member inspection system and a pipe member inspection method.

在傳統鍋爐或排熱回收鍋爐(HRSG:Heat Recovery Steam Generator)般的鍋爐設備所使用之傳熱管等的管構件,有發生腐蝕所致之薄化等之異常的情況。若這種異常發展而導致損傷的話,為了對策、復原必須花上許多時間與成本,故要求著藉由檢查來提早把握該等異常。In conventional boilers or heat recovery steam generator (HRSG: Heat Recovery Steam Generator)-like boiler equipment, tube members such as heat transfer tubes may exhibit abnormalities such as thinning due to corrosion. If such an abnormality develops and causes damage, it takes a lot of time and cost for countermeasures and restoration, so it is required to grasp such abnormality in advance by inspection.

例如專利文獻1,提案有在探傷檢查裝置***至管構件的狀態下,對管構件供給水流,藉此使探傷檢查裝置利用從水流承受到的水壓,而在管構件的內部移動。 [先前技術文獻] [專利文獻]For example, Patent Document 1 proposes that the flaw detection and inspection device is moved inside the tubular member by the water pressure received from the water flow by supplying a water flow to the tubular member in a state where the flaw detection and inspection device is inserted into the tubular member. [Prior Art Literature] [Patent Literature]

[專利文獻1]日本特開2011-75384號公報[Patent Document 1] Japanese Patent Laid-Open No. 2011-75384

[發明所欲解決之問題][Problems to be Solved by Invention]

在上述專利文獻1般之利用水壓來進行探傷檢查裝置之移動的檢查手法,必須要有對管構件供給水流用的水壓泵。在鍋爐設備所使用的管構件一般包含有撓曲部,為了對於撓曲部使探傷檢查裝置準確地通過並進行遍及廣範圍的檢查,而要求著一定程度強大的水壓。因此,水壓泵有必要成為比較大型者。且,從水壓泵供給的水流例如是透過水管來供給至管構件,但在水管與管構件的連結部為了防止水流洩漏,亦有必要在該連結部使用厚重的接頭。在這種利用水壓的檢查手法,用來實施該手法的附帶設備(水壓泵或接頭等)容易大型化這點成為課題。The inspection method in which the movement of the flaw detection and inspection apparatus using hydraulic pressure, as described in the above-mentioned Patent Document 1, requires a hydraulic pump for supplying a water flow to the pipe member. A pipe member used in boiler equipment generally includes a flexure, and a certain degree of strong water pressure is required in order to pass the flaw detection device accurately through the flexure and perform inspection over a wide range. Therefore, it is necessary for the hydraulic pump to be relatively large. In addition, the water flow supplied from the hydraulic pump is supplied to the pipe member through, for example, a water pipe. However, in order to prevent leakage of the water flow at the connection portion between the water pipe and the pipe member, it is necessary to use a heavy joint at the connection portion. In the inspection method using such a hydraulic pressure, it is a problem that the accompanying equipment (a hydraulic pump, a joint, etc.) for carrying out the method tends to be increased in size.

有鑑於上述情事,本發明的至少一實施形態,其目的在於提供管構件的檢查系統及管構件的檢查方法,可用簡易的構造,來一邊在管構件的內部移動一邊檢查管構件。 [解決問題之技術手段]In view of the above-mentioned circumstances, at least one embodiment of the present invention aims to provide a pipe member inspection system and a pipe member inspection method capable of inspecting the pipe member while moving inside the pipe member with a simple structure.

[Effect of invention]

根據本發明的至少一實施形態,可用簡易的構造,來一邊在管構件的內部移動一邊檢查管構件。According to at least one embodiment of the present invention, the pipe member can be inspected while moving inside the pipe member with a simple structure.

以下,參照附加圖式來說明本發明的幾個實施形態。但是,作為實施形態來記載或者是圖式所示之構成零件的尺寸、材質、形狀、其相對配置等,並非用來將本發明的範圍限定於此,而單純只是說明例而已。 例如,表示「於某方向」、「沿著某方向」、「平行」、「正交」、「中心」、「同心」或是「同軸」等之相對或絕對的配置表現,並不是嚴密地僅表示這種配置,而是也包含公差,或是帶有能得到相同功能之程度的角度或距離來相對位移的狀態。 例如,表示「相同」、「相等」及「均質」等之事物相等的狀態之表現,並不是嚴密地僅表示相等的狀態,而是也包含公差,或是存在有能得到相同功能之程度之差的狀態。 例如,四角形狀或圓筒形狀等之表示形狀的表現,並不是僅表示出幾何學上嚴格意義的四角形狀或圓筒形狀等之形狀,而是在能得到相同效果的範圍內,包含凹凸部或倒角部等的形狀。 另一方面,「備有」、「具有」、「具備」、「含有」、或是「有」一個構成要件等之表現,並不是將其他構成要件的存在予以除外之排他性的表現。Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples. For example, relative or absolute arrangement expressions such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric" or "coaxial" are not strictly This configuration is only shown, but also includes tolerances, or states of relative displacement with angles or distances to the extent that the same function is obtained. For example, the expression of the state of the equality of things such as "same", "equal" and "homogeneous" does not strictly mean only the state of equality, but also includes tolerance, or there is a degree to which the same function can be obtained. poor state. For example, the representation of a shape, such as a square shape or a cylindrical shape, does not only represent a shape such as a square shape or a cylindrical shape in a strict geometrical sense, but includes concavo-convex portions within a range in which the same effect can be obtained. or the shape of the chamfered part, etc. On the other hand, the expression "has", "has", "has", "contains", or "has" a constituent element is not an exclusive expression excluding the existence of other constituent elements.

(全體構造) 圖1是表示本發明之至少一實施形態之檢查系統100之全體構造的示意圖。檢查系統100,例如是將傳統鍋爐或排熱回收鍋爐(HRSG:Heat Recovery Steam Generator)般的鍋爐設備所使用之傳熱管等的管構件10當成檢查對象。管構件10具有任意形狀,其包含:具有直線形狀的直線部10a、具有彎曲形狀的彎曲部10b。(entire structure) FIG. 1 is a schematic diagram showing the overall structure of an inspection system 100 according to at least one embodiment of the present invention. The inspection system 100 takes, for example, a tube member 10 such as a heat transfer tube used in a boiler facility such as a conventional boiler or a heat recovery steam generator (HRSG: Heat Recovery Steam Generator) as an inspection object. The pipe member 10 has an arbitrary shape and includes a straight portion 10a having a straight shape and a curved portion 10b having a curved shape.

管構件10,配置在鍋爐設備之燃燒爐12的內部空間。燃燒爐12的內部空間,是被隔熱材或含有傳熱管等的壁面14給包圍而規定出來。在圖1,僅簡略表示構成燃燒爐12之壁面14的一部分。The pipe member 10 is arranged in the inner space of the combustion furnace 12 of the boiler facility. The internal space of the combustion furnace 12 is defined by being surrounded by a heat insulating material or a wall surface 14 including a heat transfer tube or the like. In FIG. 1 , only a part of the wall surface 14 constituting the combustion furnace 12 is schematically shown.

且,在壁面14設有開口部16,是作為用來對於內部空間導入或排出作業員或各種機材之際的通路。開口部16,具有可開閉的蓋構件(未圖示,是所謂的人孔蓋),因應必要來以蓋構件塞住開口部16,藉此構成為可將燃燒爐12的內部空間隔離於外部。Moreover, the opening part 16 is provided in the wall surface 14, and it is used as a passage for introducing or discharging an operator or various equipment into the internal space. The opening portion 16 has an openable and closable cover member (not shown, so-called manhole cover), and the opening portion 16 is plugged with a cover member as necessary, thereby being configured to isolate the internal space of the combustion furnace 12 from the outside .

在燃燒爐12,為了確保良好的燃燒效率,開口部16的大小是被限制成所需最低限度的大小。這是因為,若在燃燒爐12之壁面14所占之開口部16的比率較大的話,從燃燒爐12失去的熱能量會增加,而有著導致效率降低之虞。因此,能通過開口部16的機材,是被限制成比開口部16的大小還小者。In the combustion furnace 12, in order to ensure good combustion efficiency, the size of the opening portion 16 is limited to the minimum required size. This is because if the ratio of the opening 16 occupied by the wall surface 14 of the combustion furnace 12 is large, the thermal energy lost from the combustion furnace 12 increases, which may lead to a decrease in efficiency. Therefore, the material that can pass through the opening 16 is restricted to be smaller than the size of the opening 16 .

檢查系統100,具備:可從管構件10的端部***至內部的檢查裝置110、可對管構件10供給氣體的氣體供給部150。在此,圖2是將***至管構件10的檢查裝置110從側方來透視顯示的示意圖。The inspection system 100 includes an inspection device 110 that can be inserted into the inside of the pipe member 10 from an end portion thereof, and a gas supply unit 150 that can supply a gas to the pipe member 10 .

The configuration of the camera unit 60 will be described in detail later.

又,圖像記錄裝置230,可將攝影元件所攝影之即時圖像,亦即現場圖像予以顯示,亦可將現場圖像的圖像訊號輸出至外部的其他機器。藉此,進行管構件10之檢查的作業員可一邊確認管構件10之內部的狀態一邊進行管構件10的檢查。 圖像記錄裝置230,可將攝影元件所攝影之圖像的圖像訊號予以記錄,能將所記錄的圖像訊號輸出至外部的其他機器更好。藉此,可在管構件10的檢查實施之後,確認管構件10之內部的狀態。且,可比較渦電流探傷的結果與管構件10之內部的模樣,有益於檢查結果的解析。 且,圖像記錄裝置230,可將所記錄的圖像訊號予以播放來顯示為佳。藉此,不必準備用來顯示播放之圖像的其他裝置,便利性高。In addition, the image recording device 230 can display the real-time image captured by the photographing element, that is, the live image, and can also output the image signal of the live image to other external devices. Thereby, the operator who inspects the pipe member 10 can perform the inspection of the pipe member 10 while confirming the state of the inside of the pipe member 10 . The image recording device 230 can record the image signal of the image captured by the photographing element, and preferably can output the recorded image signal to other external devices. Thereby, after the inspection of the pipe member 10 is carried out, the state of the inside of the pipe member 10 can be confirmed. In addition, the results of the eddy current flaw detection can be compared with the appearance of the inside of the pipe member 10, which is useful for analysis of the inspection results. In addition, the image recording device 230 can play the recorded image signal for display. Thereby, there is no need to prepare another device for displaying the image to be played, and the convenience is high.

It is better to cover it with the outer skin. In addition, in some embodiments, it is preferable that the cord-shaped body 30 includes a tension member for bearing the tension applied to the cord-shaped body 30 . The tension member includes, for example, a wire made of a metal material such as stainless steel, and its surface is preferably covered with a film such as polyurethane.

(氣體承受部40) 如圖2所示般,在這種索狀體30,設有至少一個氣體承受部40。氣體承受部40,是設置成對於纜線狀的索狀體30部分地朝向徑方向外側突出。具體來說,在幾個實施形態,氣體承受部40,是具有球形狀的構件,該球形狀構成為覆蓋索狀體30的外周。 因此,若檢查裝置110***至管構件10的話,氣體承受部40會優先接觸於管構件10的內壁。其結果,使檢查裝置110對管構件10之內壁的接觸面積減少。藉此,在檢查裝置110於管構件10的內部移動之際,可降低與管構件10的內壁之間產生的摩擦力,檢查裝置110可在管構件10的內部滑順地移動。(Gas receiving part 40) As shown in FIG. 2 , at least one gas receiving portion 40 is provided in such a cord-shaped body 30 . The gas receiving portion 40 is provided so as to partially protrude radially outward with respect to the cable-shaped cord-shaped body 30 . Specifically, in some embodiments, the gas receiving portion 40 is a member having a spherical shape, and the spherical shape is configured to cover the outer circumference of the cord-shaped body 30 . Therefore, when the inspection device 110 is inserted into the pipe member 10 , the gas receiving portion 40 preferentially contacts the inner wall of the pipe member 10 . As a result, the contact area of the inspection apparatus 110 with respect to the inner wall of the pipe member 10 is reduced. Thereby, when the inspection apparatus 110 moves inside the pipe member 10 , the frictional force with the inner wall of the pipe member 10 can be reduced, and the inspection apparatus 110 can be smoothly moved inside the pipe member 10 .

在圖2,特別是複數個氣體承受部40,是對於沿著管構件10延伸的索狀體30空出間隔來設置。因此,即使是管構件10到達長距離的情況,亦可在管構件10的內部遍及廣範圍來滑順地移動。In FIG. 2 , in particular, the plurality of gas receiving portions 40 are provided at intervals with respect to the cord-shaped body 30 extending along the pipe member 10 . Therefore, even when the pipe member 10 reaches a long distance, the pipe member 10 can be smoothly moved over a wide range inside the pipe member 10 .

如後述般,在檢查裝置110***至管構件10的狀態下,對管構件10的內部供給氣體,藉此形成有從管構件10的端部朝向內側的氣流F。上述的氣體承受部40,是比索狀體30的外表面還往徑方向外側突出,故會承受氣流F,藉此對於檢查裝置110賦予沿著該氣流F的推進力。藉此,即使是索狀體30由含有柔軟性優異的材料來構成的情況,亦藉由氣流F所致的推進力,不會在管構件10的內部發生撓曲等所致的堵塞,可滑順地移動。As will be described later, in a state where the inspection device 110 is inserted into the pipe member 10 , gas is supplied to the inside of the pipe member 10 , thereby forming an airflow F that goes inward from the end of the pipe member 10 . The gas receiving portion 40 described above protrudes radially outward from the outer surface of the cord-shaped body 30 , and thus receives the airflow F, thereby imparting a propulsive force along the airflow F to the inspection apparatus 110 . Accordingly, even if the cord-shaped body 30 is made of a material containing excellent flexibility, the propulsion force by the airflow F does not cause clogging due to deflection or the like inside the pipe member 10, and it is possible to Move smoothly.

在本實施形態,如上述般,複數個氣體承受部40對於索狀體30空出間隔來設置,故***至管構件10的檢查裝置110,可遍及廣範圍地承受來自氣流F的推進力。In the present embodiment, as described above, since the plurality of gas receiving parts 40 are provided at intervals with respect to the cord-shaped body 30, the inspection device 110 inserted into the pipe member 10 can receive the propulsive force from the airflow F over a wide range.

在此,圖4A及圖4B是圖2之氣體承受部40的剖面圖。圖4A表示沿著索狀體30之延伸方向(長度方向)的氣體承受部40的剖面,圖4B表示對於索狀體30之貫通方向的垂直面之氣體承受部40的剖面。Here, FIGS. 4A and 4B are cross-sectional views of the gas receiving portion 40 of FIG. 2 . 4A shows a cross section of the gas receiving portion 40 along the extending direction (longitudinal direction) of the cord-shaped body 30, and FIG.

氣體承受部40,具有大致球形狀,以貫通其中心的方式設有貫通孔43。於貫通孔43,***有纜線狀的索狀體30。貫通孔43的內徑與索狀體30的外徑是設定成相對應,對於通過貫通孔43的索狀體30固定有氣體承受部40。The gas receiving portion 40 has a substantially spherical shape, and a through hole 43 is provided so as to penetrate the center thereof. A cable-shaped cord-shaped body 30 is inserted into the through hole 43 . The inner diameter of the through hole 43 is set to correspond to the outer diameter of the cord-shaped body 30 , and the gas receiving portion 40 is fixed to the cord-shaped body 30 passing through the through hole 43 .

氣體承受部40具有;以大致球形狀為基本構造的球面部42、以及對於索狀體30的延伸方向交錯,亦即面對索狀體30之長度方向的平面部44。在幾個實施形態,平面部44,是構成為與索狀體30之延伸方向呈垂直的平面。氣體承受部40,具有這種平面部44,藉此在管構件10的內部以平面部44來承受氣流F,而有效率地得到推進力。The gas receiving portion 40 has a spherical portion 42 having a substantially spherical shape as its basic structure, and a flat portion 44 staggered with respect to the extending direction of the cord-shaped body 30 , that is, facing the longitudinal direction of the cord-shaped body 30 . In some embodiments, the flat surface portion 44 is formed as a flat surface perpendicular to the extending direction of the cord-like body 30 . The gas receiving portion 40 has such a flat surface portion 44, whereby the air flow F is received by the flat surface portion 44 inside the pipe member 10, and a propulsive force is efficiently obtained.

又,在圖2雖舉例出管構件10之內部的氣流F為單方向的情況,但氣流F為反方向亦可(隨著時間使氣流F的方向或強度變化亦可)。對應於此,突出部122在貫通孔43的兩側具有一對氣體受面124。藉此,無關管構件10之內部的氣流F方向,能從氣流F得到推進力。2 illustrates the case where the airflow F inside the pipe member 10 is unidirectional, the airflow F may be reversed (the direction or intensity of the airflow F may be changed over time). Correspondingly, the protruding portion 122 has a pair of gas receiving surfaces 124 on both sides of the through hole 43 . Thereby, the propulsion force can be obtained from the airflow F regardless of the direction of the airflow F inside the duct member 10 .

且,在幾個實施形態,氣體承受部40,是構成為在內部形成有空洞部46。藉此,可使氣體承受部40輕量化。即使氣體承受部40單個的重量的減輕量較小,但在索狀體30的長度較長,且安裝在索狀體30的氣體承受部40的個數較多的情況,作為檢查裝置110全體之重量的減輕量會比較大。於是,可有效地減輕檢查裝置110的重量。Furthermore, in some embodiments, the gas receiving portion 40 is configured to have a cavity portion 46 formed therein. Thereby, the weight of the gas receiving portion 40 can be reduced. Even if the weight reduction of the gas receiving portion 40 is small, when the length of the cord-shaped body 30 is long and the number of gas receiving portions 40 attached to the cord-shaped body 30 is large, the inspection apparatus 110 as a whole is used as a whole. The weight reduction will be larger. Thus, the weight of the inspection device 110 can be effectively reduced.

(關於氣體承受部40A) 以下,參照圖5,針對配置在索狀體30之最前端側的氣體承受部40A進行說明。圖5是將沿著索狀體30之延伸方向的氣體承受部40A之剖面予以示意表示的圖。 在幾個實施形態,在配置在索狀體30之最前端側的氣體承受部40A安裝有攝影機單元60。在幾個實施形態,沿著索狀體30之延伸方向的攝影機單元60之長度比較長的情況,沿著索狀體30之延伸方向的氣體承受部40A之長度,構成為比其他氣體承受部40還長亦可。 在幾個實施形態,在氣體承受部40A的至少基端側具有平面部44為佳。(About the gas receiving part 40A) Hereinafter, with reference to FIG. 5, the gas receiving part 40A arrange|positioned at the frontmost side of the cord-shaped body 30 is demonstrated. FIG. 5 is a diagram schematically showing a cross section of the gas receiving portion 40A along the extending direction of the cord-shaped body 30 . In some embodiments, the camera unit 60 is attached to the gas receiving portion 40A arranged on the frontmost end side of the cord-shaped body 30 . In some embodiments, when the length of the camera unit 60 along the extending direction of the cord-like body 30 is relatively long, the length of the gas receiving portion 40A along the extending direction of the cord-like body 30 is configured to be longer than that of the other gas receiving portions 40 can also be long. In some embodiments, it is preferable to have the flat surface portion 44 on at least the proximal end side of the gas receiving portion 40A.

在幾個實施形態,可從氣體承受部40A之前端側的開口402使被攝體光射入至攝影機單元60之被攝體光的射入部62。亦即,在幾個實施形態,在氣體承受部40A之前端側的端部404或從端部404稍微往基端側後退的位置,配置有被攝體光的射入部62。藉此,在幾個實施形態,於被攝體光的射入部62,可供來自索狀體30之前方(前端側)的被攝體光射入。亦即,在幾個實施形態,可藉由攝影機單元60來取得比氣體承受部40A還靠索狀體30之前方(前端側)的圖像。In some embodiments, the subject light can be incident on the subject light incident portion 62 of the camera unit 60 from the opening 402 on the front end side of the gas receiving portion 40A. That is, in some embodiments, the incident portion 62 of the subject light is arranged at the end portion 404 on the front end side of the gas receiving portion 40A or at a position slightly retreated from the end portion 404 to the proximal end side. As a result, in some embodiments, the subject light from the front (front end side) of the cord-shaped body 30 can be incident on the subject light incident portion 62 . That is, in some embodiments, the camera unit 60 can acquire an image of the front (front end side) of the cord-shaped body 30 rather than the gas receiving portion 40A.

在幾個實施形態,於攝影機單元60的側部,例如將固定螺絲92的前端予以抵接藉此將攝影機單元60固定於氣體承受部40A亦可。又,在從攝影機單元60的側部將固定螺絲92的前端予以抵接等之對於攝影機單元60的側部局部施加力的構造的情況,設置覆蓋攝影機單元60之側部的圓筒構件94為佳。亦即,將攝影機單元60收納在圓筒構件94的內側,藉此使來自固定螺絲92之前端的按壓力不會對於攝影機單元60的側部局部地作用為佳。又,圓筒構件94,例如是以金屬等之具有抵抗來自固定螺絲92之前端之按壓力之強度的材料所構成為佳。In some embodiments, the camera unit 60 may be fixed to the gas receiving portion 40A by, for example, abutting the front end of the fixing screw 92 on the side of the camera unit 60 . In addition, in the case of a structure in which a force is locally applied to the side of the camera unit 60 by abutting the front end of the fixing screw 92 from the side of the camera unit 60, the cylindrical member 94 covering the side of the camera unit 60 is provided as good. That is, it is preferable that the camera unit 60 is housed inside the cylindrical member 94 so that the pressing force from the front end of the fixing screw 92 does not act locally on the side of the camera unit 60 . In addition, the cylindrical member 94 is preferably formed of a material having strength to resist the pressing force from the front end of the fixing screw 92, such as metal, for example.

在幾個實施形態,於保護層120的側部,例如將固定螺絲92的前端予以抵接藉此將索狀體30固定於氣體承受部40A亦可。該情況時,以來自固定螺絲92之前端的按壓力不會壓壞保護層120的方式,在保護層120的內側例如配置金屬製的護套96為佳。In some embodiments, the cable body 30 may be fixed to the gas receiving portion 40A by, for example, abutting the front end of the fixing screw 92 on the side of the protective layer 120 . In this case, it is preferable that the protective layer 120 is provided with, for example, a metal sheath 96 inside the protective layer 120 so that the pressing force from the front end of the fixing screw 92 does not crush the protective layer 120 .

(關於定心構件80) 在幾個實施形態,在管構件10之徑方向的中心設有用來靠近檢測部50的定心構件80。圖6,表示從索狀體30的延伸方向(長度方向)來觀看幾個實施形態之定心構件80時之示意外觀的圖。 幾個實施形態的定心構件80,具有:具有大致圓盤形狀的圓盤構件82、設在圓盤構件82之外周面82a的刷部84。於圓盤構件82,設有將圓盤構件82的中心予以貫通的貫通孔86。在幾個實施形態的定心構件80,刷部84,在圓盤構件82的外周面82a具有刷毛群84a,其朝向圓盤構件82的徑方向外側植設。(Regarding the centering member 80) In some embodiments, a centering member 80 for approaching the detection portion 50 is provided at the center of the pipe member 10 in the radial direction. FIG. 6 is a diagram showing a schematic appearance of the centering member 80 of several embodiments when viewed from the extending direction (longitudinal direction) of the cord-like body 30 . The centering member 80 of some embodiments includes a disk member 82 having a substantially disk shape, and a brush portion 84 provided on the outer peripheral surface 82a of the disk member 82 . The disk member 82 is provided with a through hole 86 penetrating the center of the disk member 82 . In the centering member 80 of some embodiments, the brush portion 84 has the bristle group 84 a on the outer peripheral surface 82 a of the disk member 82 , and is implanted toward the radially outer side of the disk member 82 .

在幾個實施形態,於貫通孔86***有纜線狀的索狀體30。貫通孔86的內徑與索狀體30的外徑是對應地設定,對於通過貫通孔86的索狀體30,固定有定心構件80。In some embodiments, the cable-shaped cord-shaped body 30 is inserted into the through hole 86 . The inner diameter of the through hole 86 is set corresponding to the outer diameter of the cord-shaped body 30 , and the centering member 80 is fixed to the cord-shaped body 30 passing through the through hole 86 .

在幾個實施形態,例如圖2所示般,在配置於索狀體30之最前端側的氣體承受部40A之基端側的端部附近配置定心構件80為佳。藉此,可使安裝在氣體承受部40A的攝影機單元60之位置往管構件10的徑方向中心靠近,並可使被攝體光之射入部62的面向接近管構件10的軸方向。於是,可藉由攝影機單元60來較均勻地拍攝管構件10的內周。且,可抑制氣體承受部40A在管構件10的內部受到重力的影響而下垂的情況,故可抑制氣體承受部40A的磨損量。In some embodiments, for example, as shown in FIG. 2 , it is preferable to arrange the centering member 80 in the vicinity of the end portion on the proximal end side of the gas receiving portion 40A arranged on the most distal end side of the cord-shaped body 30 . Thereby, the position of the camera unit 60 mounted on the gas receiving portion 40A can be brought closer to the radial center of the tube member 10 , and the surface of the incident portion 62 of the subject light can be brought closer to the axial direction of the tube member 10 . Therefore, the inner circumference of the pipe member 10 can be photographed relatively uniformly by the camera unit 60 . In addition, since the gas receiving portion 40A is prevented from hanging down under the influence of gravity inside the pipe member 10, the wear amount of the gas receiving portion 40A can be restrained.

在幾個實施形態,例如圖2所示般,在渦電流探傷感測器70的基端側及前端側,在渦電流探傷感測器70的端部附近配置定心構件80為佳。藉此,可使渦電流探傷感測器70的位置靠近管構件10的徑方向中心。於是,可抑制渦電流探傷感測器70的檢測精度在管構件10的周方向因位置而不同的情況。且,可抑制渦電流探傷感測器70在管構件10的內部受到重力的影響而下垂的情況,故可抑制渦電流探傷感測器70的磨損量。In some embodiments, for example, as shown in FIG. 2 , it is preferable to arrange the centering members 80 near the ends of the eddy current flaw detection sensor 70 on the proximal end side and the distal end side of the eddy current flaw detection sensor 70 . Thereby, the position of the eddy current flaw detection sensor 70 can be brought close to the center in the radial direction of the pipe member 10 . Therefore, the detection accuracy of the eddy current flaw detection sensor 70 can be suppressed from being different depending on the position in the circumferential direction of the pipe member 10 . In addition, since the eddy current flaw detection sensor 70 can be suppressed from sagging under the influence of gravity inside the pipe member 10, the wear amount of the eddy current flaw detection sensor 70 can be suppressed.

又,在幾個實施形態的定心構件80,刷部84的外徑是與管構件10的內徑相同或比管構件10的內徑還大為佳。藉此,在定心構件80***至管構件10的內部之際,刷毛群84a會遍及管構件10的圓周方向全體來適當地彎曲,藉此可使檢測部50更靠近管構件10的徑方向中心。Furthermore, in the centering member 80 of some embodiments, the outer diameter of the brush portion 84 is preferably the same as or larger than the inner diameter of the pipe member 10 . Thereby, when the centering member 80 is inserted into the pipe member 10 , the bristle group 84 a is appropriately bent over the entire circumferential direction of the pipe member 10 , whereby the detection portion 50 can be brought closer to the radial direction of the pipe member 10 . center.

在幾個實施形態,對於渦電流探傷感測器70,含有:連接於氣流F之上游側的第1索狀體30a、連接於氣流F之下游側的第2索狀體30b。而且,在幾個實施形態,第1索狀體30a及第2索狀體30b,分別至少安裝有一個氣體承受部40。藉此,檢查裝置110藉由設在渦電流探傷感測器70之兩側的第1索狀體30a及第2索狀體30b來遍及全體得到均等的推進力,可在管構件10的內部滑順地移動。In some embodiments, the eddy current flaw detector 70 includes a first cord-shaped body 30a connected to the upstream side of the airflow F and a second cord-shaped body 30b connected to the downstream side of the airflow F. Furthermore, in some embodiments, at least one gas receiving portion 40 is attached to each of the first cord-shaped body 30a and the second cord-shaped body 30b. As a result, the inspection apparatus 110 can obtain a uniform propulsion force throughout the entirety of the inspection apparatus 110 by the first cord-shaped body 30 a and the second cord-shaped body 30 b provided on both sides of the eddy current flaw detector 70 , and the inside of the pipe member 10 can be Move smoothly.

Here, FIG. 7 is a cross-sectional view of the insertion jig 130 of FIG. 1 .

***治具130具有本體部134,其含有可供檢查裝置110通過內部的導入路132。在本體部134的一端側,設有用來與管構件10的端部連結的第1連結部136。第1連結部136,含有可與管構件10的端部整合的突緣,透過由彈性材料所成之O型環那般的密封構件(未圖示),而構成為可對於管構件10的端部密閉連結。The insertion jig 130 has a main body portion 134 including an introduction passage 132 through which the inspection device 110 can pass. One end side of the main body portion 134 is provided with a first connecting portion 136 for connecting with the end portion of the pipe member 10 . The first connecting portion 136 includes a flange that can be integrated with the end of the pipe member 10, and is configured to be connected to the pipe member 10 through a sealing member (not shown) such as an O-ring made of an elastic material. End sealed connection.

在本體部134的另一端側,設有第2連結部140,其用來連結於從外部送入檢查裝置110用的導管構件138。在第2連結部140,導管構件138的端部被包住,從其外側藉由水管綁帶142來綁緊,藉此構成可密閉連結。The other end side of the main body part 134 is provided with a second connection part 140 for connection to the catheter member 138 for sending the inspection apparatus 110 from the outside. In the second connection portion 140, the end portion of the duct member 138 is wrapped, and is fastened by the water pipe band 142 from the outside, thereby forming a hermetic connection.

於導管構件138,如圖1所示般,藉由作業員來從外部***檢查裝置110。***至導管構件138的檢查裝置110,是透過***治具130的導入路132,而被送往管構件10。As shown in FIG. 1 , the inspection apparatus 110 is inserted into the catheter member 138 by an operator from the outside. The inspection device 110 inserted into the catheter member 138 is sent to the tube member 10 through the introduction channel 132 of the insertion jig 130 .

在此,***治具130,具有氣體供給管146,其含有構成為與導入路132合流的氣體供給路144。在氣體供給管146的一端側,從氣體供給部150(參照圖1)透過導管構件152供給有氣體。氣體供給部150位於燃燒爐12的外部,故導管構件152是透過設在燃燒爐12之壁面14的開口部16,來連結氣體供給部150與氣體供給管146。又,氣體供給部150為可搬式的空氣壓縮機、壓縮空氣的壓縮瓶等皆可,為配置有檢查對象之管構件10的工廠中之作業用氣體的供給源亦可。Here, the insertion jig 130 has a gas supply pipe 146 including a gas supply passage 144 configured to merge with the introduction passage 132 . On one end side of the gas supply pipe 146 , the gas is supplied from the gas supply part 150 (see FIG. 1 ) through the duct member 152 . Since the gas supply part 150 is located outside the combustion furnace 12 , the duct member 152 connects the gas supply part 150 and the gas supply pipe 146 through the opening 16 provided in the wall surface 14 of the combustion furnace 12 . In addition, the gas supply part 150 may be a portable air compressor, a compressed air bottle, or the like, and may be a supply source of working gas in a factory where the pipe member 10 to be inspected is arranged.

氣體供給管146的另一端側,是與本體部134構成為一體,在其內部,氣體供給路144構成為與導入路132合流。因此,被供給至氣體供給管146的氣體,是從氣體供給路144經過導入路132,被導引至管構件10。如此一來,在管構件10的內部,形成有氣流F。The other end side of the gas supply pipe 146 is formed integrally with the main body portion 134 , and inside the gas supply passage 144 is formed so as to merge with the introduction passage 132 . Therefore, the gas supplied to the gas supply pipe 146 is guided to the pipe member 10 from the gas supply passage 144 through the introduction passage 132 . In this way, the airflow F is formed inside the pipe member 10 .

又,於氣體供給管146,設有調整閥154,其用來調整來自氣體供給部150的氣體供給量。In addition, the gas supply pipe 146 is provided with an adjustment valve 154 for adjusting the gas supply amount from the gas supply part 150 .

如上述般藉由***治具130,透過導入路132來***檢查裝置110,並從氣體供給管146供給有氣體,藉此利用形成在管構件10之內部的氣流F,使檢查裝置110的移動成為可能。檢查裝置110具有索狀體30藉此柔軟地構成,但在管構件10內部之檢查裝置110的移動,是如上述般利用由氣流F所得到的推進力,藉此可沿著具有複雜形狀的管構件10來滑順地行進。As described above, by inserting the jig 130, the inspection device 110 is inserted through the introduction path 132, and the gas is supplied from the gas supply pipe 146, whereby the gas flow F formed in the pipe member 10 is used to move the inspection device 110. become possible. The inspection device 110 has the cord-like body 30 and is thus formed in a flexible manner, but the movement of the inspection device 110 inside the pipe member 10 utilizes the propulsive force obtained by the air flow F as described above, thereby allowing the inspection device 110 to move along the complex-shaped The tubular member 10 travels smoothly.

(編碼器156) 且,檢查系統100,亦可具備累計檢查裝置110對管構件10之***量的編碼器156。圖8A及圖8B是表示圖1之檢查系統100所具備之編碼器156之一例的示意圖。(encoder 156) In addition, the inspection system 100 may include an encoder 156 that integrates the amount of insertion of the inspection device 110 into the pipe member 10 . 8A and 8B are schematic diagrams showing an example of the encoder 156 included in the inspection system 100 of FIG. 1 .

編碼器156,具備一對旋轉構件158a、158b,其透過設在管構件10之管壁之一部分的開口部157,而可對於通過管構件10之內部的檢查裝置110進行接觸。一對旋轉構件158a、158b是彼此相對向,且配置成從兩側夾住檢查裝置110。一對旋轉構件158a、158b,接觸於檢查裝置110,藉此伴隨著於管構件10之內部之檢查裝置110的移動而旋轉,藉此累計檢查裝置110對管構件10的***量。The encoder 156 includes a pair of rotating members 158a and 158b, and is capable of contacting the inspection device 110 passing through the inside of the pipe member 10 through an opening 157 provided in a part of the pipe wall of the pipe member 10 . The pair of rotating members 158a and 158b are opposed to each other, and are arranged to sandwich the inspection device 110 from both sides. The pair of rotating members 158a and 158b are in contact with the inspection device 110, and thereby rotate along with the movement of the inspection device 110 inside the pipe member 10, thereby accumulating the insertion amount of the inspection device 110 into the pipe member 10.

在此,一對旋轉構件158a、158b,是對於檢查裝置110彈性地彈推。因此,如圖8A所示般,檢查裝置110之中直徑比較大的氣體承受部40在通過時,是藉由突出部來將一對旋轉構件158a、158b的間隔推開。另一方面,如圖8B所示般,檢查裝置110之中直徑比較小的索狀體30在通過時,一對旋轉構件158a、158b的間隔會變小。如上述般,因應檢查裝置110的直徑使一對旋轉構件158a、158b的間隔變化,藉此良好地確保一對旋轉構件158a、158b對檢查裝置110的接觸狀態。Here, the pair of rotating members 158a and 158b are elastically pushed against the inspection device 110 . Therefore, as shown in FIG. 8A , when the gas receiving portion 40 having a relatively large diameter in the inspection apparatus 110 passes, the distance between the pair of rotating members 158a and 158b is pushed apart by the protruding portion. On the other hand, as shown in FIG. 8B , when the cord-shaped body 30 having a relatively small diameter in the inspection apparatus 110 passes, the interval between the pair of rotating members 158a and 158b is reduced. As described above, by changing the interval between the pair of rotating members 158a and 158b according to the diameter of the inspection device 110 , the contact state of the pair of rotating members 158a and 158b with respect to the inspection device 110 is well ensured.

回到圖1,檢查系統100,具備解析裝置200,其將***至管構件10的檢查裝置110所取得的檢查訊號予以解析,藉此檢查管構件10。檢查裝置110是在管構件10的內部一邊移動一邊藉由檢查裝置110來取得圖像訊號及檢查訊號。該圖像訊號,透過索狀體30所含的攝影機纜線64(參照圖3A、圖3B)被傳送至圖像記錄裝置230。該檢查訊號,透過索狀體30所含的訊號纜線118(參照圖3A)被傳送至解析裝置200。Returning to FIG. 1 , the inspection system 100 includes an analysis device 200 that inspects the tubular member 10 by analyzing the inspection signal acquired by the inspection device 110 inserted into the tubular member 10 . The inspection device 110 acquires image signals and inspection signals through the inspection device 110 while moving inside the pipe member 10 . The image signal is transmitted to the image recording device 230 through the camera cable 64 (see FIGS. 3A and 3B ) included in the cable body 30 . The inspection signal is transmitted to the analysis device 200 through the signal cable 118 (refer to FIG. 3A ) included in the cord-shaped body 30 .

解析裝置200,是藉由電腦那種演算處理裝置所構成,構成為可實施本發明之至少一實施形態之檢查方法。例如,解析裝置200,是在電腦那種演算處理裝置,安裝可實行本發明之至少一實施形態之檢查方法的程式,藉此來構成。該情況時,可實行本發明之至少一實施形態之檢查方法的程式,是將可讀取地儲存於既定儲存媒體者,以電腦那種演算處理裝置來讀取藉此來安裝亦可。The analysis device 200 is constituted by an arithmetic processing device such as a computer, and is configured to implement the inspection method of at least one embodiment of the present invention. For example, the analysis device 200 is configured by installing a program capable of executing the inspection method of at least one embodiment of the present invention in an arithmetic processing device such as a computer. In this case, a program capable of implementing the inspection method of at least one embodiment of the present invention may be stored in a predetermined storage medium in a readable manner, and may be read and installed by an arithmetic processing device such as a computer.

(關於檢查方法) 接著使用具有上述構造的檢查系統100,來說明檢查方法。圖9是依照每個工序來表示本發明之至少一實施形態之檢查方法的流程圖。(about inspection method) Next, an inspection method will be described using the inspection system 100 having the above-described configuration. FIG. 9 is a flowchart showing an inspection method according to at least one embodiment of the present invention for each step.

首先,對於成為檢查對象的管構件10,安裝上述的***治具130(步驟S1)。***治具130,將其一端側連結於管構件10的端部,藉此對於管構件10來安裝(藉此形成有第1連結部136)。第1連結部136,是在與設在管構件10之端部的突緣部之間,中介有O型環那種密封構件(未圖示),藉此使管構件10與***治具130之間密閉連結。First, the above-mentioned insertion jig 130 is attached to the pipe member 10 to be inspected (step S1). The jig 130 is inserted and attached to the pipe member 10 by connecting one end side thereof to the end portion of the pipe member 10 (thereby, the first connection portion 136 is formed). The first connection portion 136 is formed by interposing a sealing member (not shown) such as an O-ring between the flange portion provided at the end of the pipe member 10 and the pipe member 10 and the insertion jig 130 . A closed connection between them.

接著,對於安裝在管構件10的***治具130,透過導管構件152來連接氣體供給部150(步驟S2)。如圖1所示般,氣體供給部150位於燃燒爐12的外部,故導管構件152通過設在燃燒爐12之壁面14的開口部16,且透過導管構件152來連接於***治具130的氣體供給管146。Next, the gas supply part 150 is connected to the insertion jig 130 attached to the pipe member 10 through the duct member 152 (step S2). As shown in FIG. 1 , since the gas supply part 150 is located outside the combustion furnace 12 , the duct member 152 passes through the opening 16 provided in the wall surface 14 of the combustion furnace 12 and is connected to the gas inserted into the jig 130 through the duct member 152 Supply tube 146 .

接著,開始從氣體供給部150對***治具130供給空氣(步驟S3)。來自氣體供給部150的空氣供給,是將設在氣體供給管146的調整閥154打開而開始。藉此,從氣體供給部150供給至***治具130的空氣,是從氣體供給路144經由導入路132,被導引至管構件10。如此一來,在管構件10的內部,形成有氣流F。Next, the air supply from the gas supply part 150 to the insertion jig 130 is started (step S3). The air supply from the gas supply part 150 is started by opening the regulating valve 154 provided in the gas supply pipe 146 . Thereby, the air supplied from the gas supply part 150 to the insertion jig 130 is guided to the pipe member 10 from the gas supply passage 144 via the introduction passage 132 . In this way, the airflow F is formed inside the pipe member 10 .

又,往***治具130的空氣供給量,在之後的步驟S4,是對應於對於***至***治具130的檢查裝置110應賦予的推進力來調整。這種空氣供給量的調整,是控制調整閥154的開度藉此進行。In addition, the amount of air supplied to the insertion jig 130 is adjusted in accordance with the propulsive force to be given to the inspection device 110 inserted into the insertion jig 130 in the subsequent step S4 . Such adjustment of the air supply amount is performed by controlling the opening degree of the regulating valve 154 .

接著,準備檢查裝置110、解析裝置200及圖像記錄裝置230,將檢查裝置110事先連接於解析裝置200及圖像記錄裝置230(步驟S4)。在此,解析裝置200及圖像記錄裝置230,具有比燃燒爐12的開口部16還小的尺寸,故可透過開口部16從外部帶到燃燒爐12的內部,且配置在檢查對象的管構件10附近(燃燒爐12的內部)。Next, the inspection apparatus 110, the analysis apparatus 200, and the image recording apparatus 230 are prepared, and the inspection apparatus 110 is connected to the analysis apparatus 200 and the image recording apparatus 230 in advance (step S4). Here, the analyzing device 200 and the image recording device 230 have smaller dimensions than the opening 16 of the combustion furnace 12, so that they can be brought to the inside of the combustion furnace 12 from the outside through the opening 16, and are arranged in the pipe to be inspected. Near member 10 (inside combustion furnace 12).

又,解析裝置200及圖像記錄裝置230的動作所必要的電力,是從設置在燃燒爐12之外部的電源部210透過電源纜線220來供給。電源纜線220,設置成通過設在燃燒爐12之壁面14的開口部16。In addition, the electric power necessary for the operation of the analyzing apparatus 200 and the image recording apparatus 230 is supplied from the power supply unit 210 provided outside the combustion furnace 12 through the power supply cable 220 . The power cable 220 is provided so as to pass through the opening 16 provided in the wall surface 14 of the combustion furnace 12 .

接著,對於***治具130來***檢查裝置110(步驟S5)。檢查裝置110是以事先連接於解析裝置200及圖像記錄裝置230的狀態,透過***治具130的導入路132,而被送往管構件10的內部。此時,於管構件10的內部或導入路132,是藉由步驟S3所供給的空氣來形成氣流F,故檢查裝置110是被賦予氣流F所致的推進力。藉此,使檢查裝置110對於管構件10的內部滑順地***。Next, the inspection device 110 is inserted into the insertion jig 130 (step S5). The inspection apparatus 110 is connected to the analysis apparatus 200 and the image recording apparatus 230 in advance, and is sent to the inside of the pipe member 10 through the introduction path 132 of the insertion jig 130 . At this time, since the air flow F is formed inside the pipe member 10 or the introduction path 132 by the air supplied in step S3, the inspection apparatus 110 is given a propulsive force by the air flow F. As shown in FIG. Thereby, the inspection device 110 is smoothly inserted into the pipe member 10 .

接著,在管構件10的內部一邊使檢查裝置110移動,一邊實施檢查裝置110所致的檢查(步驟S6)。在管構件10的內部之檢查裝置110的移動,是調整對於管構件10的空氣供給量來進行。這種空氣供給量的調整,是控制調整閥154的開度藉此進行。Next, the inspection by the inspection device 110 is performed while moving the inspection device 110 inside the pipe member 10 (step S6 ). The movement of the inspection device 110 inside the pipe member 10 is performed by adjusting the air supply amount to the pipe member 10 . Such adjustment of the air supply amount is performed by controlling the opening degree of the regulating valve 154 .

檢查裝置110的測量資料,是隨時傳送並累積於解析裝置200。同樣地,檢查裝置110的圖像資料,是隨時傳送並累積於圖像記錄裝置230。 在解析裝置200,取得來自檢查裝置110的測量資料,並參照圖8取得上述編碼器156的累計值,並彼此配對來管理。藉此,解析裝置200,可判別檢查裝置110的各測量資料是在管構件10的哪個位置取得的。然後,解析裝置200,將如此管理的測量資料予以解析,藉此實施管構件10之各位置的檢查。 又,在圖像記錄裝置230,取得來自檢查裝置110的圖像資料,並參照圖8取得上述編碼器156的累計值,並彼此配對來管理亦可。The measurement data of the inspection device 110 are transmitted and accumulated in the analysis device 200 at any time. Likewise, the image data of the inspection device 110 is transmitted and accumulated in the image recording device 230 at any time. The analysis device 200 acquires the measurement data from the inspection device 110 and acquires the integrated value of the encoder 156 with reference to FIG. 8 , and manages them in pairs. Thereby, the analysis apparatus 200 can discriminate at which position of the pipe member 10 each measurement data of the inspection apparatus 110 was acquired. Then, the analysis apparatus 200 analyzes the measurement data managed in this way, and carries out the inspection of each position of the pipe member 10 by it. In addition, the image recording device 230 may acquire image data from the inspection device 110, acquire the accumulated value of the encoder 156 with reference to FIG. 8, and manage them by pairing with each other.

接著,步驟S6的檢查,是針對管構件10事先設定的既定檢查範圍來判斷是否結束(步驟S7)。在針對檢查範圍的檢查尚未結束的情況(步驟S7:NO),使處理回到步驟S6,藉此對剩下的檢查範圍實施檢查。在針對檢查範圍的檢查結束的情況(步驟S7:YES),結束一連串的檢查方法(END)。Next, in the inspection of step S6, it is judged whether or not to end the inspection with respect to the predetermined inspection range set in advance for the pipe member 10 (step S7). When the inspection for the inspection range has not been completed (step S7: NO), the process is returned to step S6, whereby inspection is performed on the remaining inspection range. When the inspection for the inspection range ends (step S7: YES), a series of inspection methods are ended (END).

根據以上說明般的上述實施形態,對於***有檢查裝置110的管構件10供給氣體,而在管構件10的內部產生氣流,藉此可一邊使檢查裝置110移動一邊實施檢查。使用這種氣流的檢查裝置110之移動,比起利用水壓的情況,附帶設備較為簡易,故操作亦容易。According to the above-described embodiment as described above, gas is supplied to the pipe member 10 into which the inspection device 110 is inserted, and the gas flow is generated inside the pipe member 10 , whereby inspection can be performed while moving the inspection device 110 . The movement of the inspection device 110 using such an air flow is simpler than the case of using water pressure, and the accompanying equipment is simpler, so the operation is also easy.

本發明並不限定於上述實施形態,還包含了在上述實施形態加上變形的形態、將該等形態適當組合的形態。 例如,在上述的幾個實施形態,檢查裝置110,具有攝影機單元60,其具備作為檢測部50的被攝體光的射入部62。亦即,在上述的幾個實施形態,是在安裝於氣體承受部40A的攝影機單元60,配置有用來將被攝體光轉換成電氣訊號之未圖示的攝影元件,並將攝影元件***至管構件10的內部。但是,攝影元件,並不構成為***至管構件10的內部亦可。亦即,在配置於管構件10之外部的觀察裝置(例如圖像記錄裝置230)配置攝影元件,使用光纖來將管構件10之內部的被攝體光導引至該攝影元件亦可。該情況時,取代攝影機單元60的攝影機纜線64來將該光纖配置在索狀體30內,將該光纖纜線的前端部分安裝於氣體承受部40A亦可。該情況時,該光纖纜線的前端部分會成為作為檢測部50的被攝體光的射入部62。The present invention is not limited to the above-mentioned embodiment, and includes a form in which a modification is added to the above-mentioned embodiment, and a form in which these forms are appropriately combined. For example, in the above-described embodiments, the inspection apparatus 110 includes the camera unit 60 including the object light incident unit 62 serving as the detection unit 50 . That is, in the above-mentioned several embodiments, the camera unit 60 attached to the gas receiving portion 40A is provided with a photographing element (not shown) for converting subject light into electrical signals, and the photographing element is inserted into the camera unit 60 . The interior of the pipe member 10 . However, the imaging element does not have to be configured to be inserted into the tube member 10 . That is, an imaging element may be arranged in an observation device (eg, the image recording device 230 ) arranged outside the tube member 10 , and an optical fiber may be used to guide the subject light inside the tube member 10 to the imaging element. In this case, instead of the camera cable 64 of the camera unit 60, the optical fiber may be arranged in the cord-shaped body 30, and the tip portion of the optical fiber cable may be attached to the gas receiving portion 40A. In this case, the tip portion of the optical fiber cable serves as the incident portion 62 of the subject light of the detection portion 50 .

且,例如,在上述的幾個實施形態,藉由在配置在索狀體30之最前端側的氣體承受部40A所安裝的攝影機單元60,來取得比氣體承受部40A還靠索狀體30之前方(前端側)之管構件10之內周面的圖像。但是,藉由在該氣體承受部40A以外之其他的氣體承受部40所安裝的攝影機單元60,來取得管構件10之內周面的圖像亦可。 且,例如,對於配置在索狀體30之最前端側的氣體承受部40A,或其他的氣體承受部40,藉由朝向管構件10之徑方向外側的攝影機單元來取得管構件10之內周面的圖像亦可。該情況時,是在圓周方向空出間隔來配置複數個攝影機單元,藉此遍及管構件10的圓周方向全體來取得圖像亦可,使一個攝影機單元於圓周方向旋轉,藉此遍及管構件10的圓周方向全體來取得圖像亦可。Furthermore, for example, in the above-mentioned several embodiments, the camera unit 60 is attached to the gas receiving portion 40A arranged on the most distal side of the cable-like body 30 to obtain the cord-like body 30 that is closer to the gas receiving portion 40A than the gas receiving portion 40A. An image of the inner peripheral surface of the pipe member 10 in the front (front end side). However, the image of the inner peripheral surface of the pipe member 10 may be acquired by the camera unit 60 attached to the gas receiving portion 40 other than the gas receiving portion 40A. And, for example, with respect to the gas receiving portion 40A arranged on the most distal end side of the cord-shaped body 30, or the other gas receiving portion 40, the inner circumference of the pipe member 10 is obtained by the camera unit facing the outer side in the radial direction of the pipe member 10. A face image is also acceptable. In this case, by arranging a plurality of camera units at intervals in the circumferential direction, an image may be acquired over the entire circumferential direction of the pipe member 10, and one camera unit may be rotated in the circumferential direction to cover the pipe member 10. It is also possible to obtain an image in the entire circumferential direction of the image.

且,例如,在上述的幾個實施形態,檢查裝置110是構成為進行渦電流探傷,但亦可取代渦電流探傷,或是與渦電流探傷一起進行超音波探傷。Furthermore, for example, in the above-mentioned several embodiments, the inspection apparatus 110 is configured to perform eddy current flaw detection, but ultrasonic flaw detection may be performed instead of eddy current flaw detection or together with eddy current flaw detection.

In the inspection system 100 of a pipe member according to at least one embodiment of the present invention, the inspection apparatus 110 includes a cord-shaped body 30 and a gas receiving portion 40 attached to the cord-shaped body 30 .

根據上述(1)的構造,對於***有檢查裝置110的管構件10供給氣體,藉此使氣體承受部40承受在管構件10內部所產生的氣流F,藉此得到使檢查裝置110在管構件10的內部移動用的推進力。藉此,可在管構件10的內部一邊使檢查裝置110移動一邊實施管構件10的檢查。使用這種氣流F的檢查裝置110之移動,比起利用水壓的情況,附帶設備較為簡易,故操作亦容易。According to the structure of (1) above, by supplying gas to the pipe member 10 into which the inspection device 110 is inserted, the gas receiving portion 40 receives the gas flow F generated inside the pipe member 10 , thereby obtaining the inspection device 110 in the pipe member. 10 propulsion for internal movement. Thereby, the inspection of the pipe member 10 can be performed while moving the inspection apparatus 110 inside the pipe member 10 . The movement of the inspection device 110 using the air flow F is simpler than the case of using the water pressure, and therefore the operation is easy.

(2)在幾個實施形態,上述(1)的構造中,檢查裝置110,至少具有一種類的檢測部50。(2) In some embodiments, in the structure of (1) above, the inspection device 110 includes at least one type of detection unit 50 .

根據上述(2)的構造,可在管構件10的內部一邊使檢查裝置110移動一邊實施至少一種類的檢查。According to the structure of the above-mentioned (2), at least one type of inspection can be performed while moving the inspection device 110 inside the pipe member 10 .

Furthermore, according to the structure of the above (3), even if the pipe member 10 has a bending section such as a bending portion, the inspection apparatus 110 can pass through, so that the ratio of the bending section of the pipe member 10 to the bending section such as a bending section can be obtained. Also an image of the interior of the tube member 10 in the latter section. Therefore, it is not necessary to cut the pipe member 10 in order to obtain an image of the inside of the pipe member 10 in a section after the bending section or the like.

(4)在幾個實施形態,上述(3)的構造中,上述至少一種類的檢測部50,進一步含有渦電流探傷用的感測器(渦電流探傷感測器)70。(4) In some embodiments, in the structure of (3) above, the at least one type of detection unit 50 further includes a sensor for eddy current flaw detection (eddy current flaw detection sensor) 70 .

根據上述(4)的構造,可實施管構件10的渦電流探傷檢查。且,根據上述(4)的構造,管構件10之內部之圖像的取得與管構件10的渦電流探傷檢查可同時實施,故可縮短檢查期間。且,根據上述(4)的構造,進行檢查的作業員會觀察管構件10之內部的圖像,在從該圖像判斷沒有必要進行渦電流探傷檢查的區間,不進行渦電流探傷檢查,在從該圖像判斷有必要進行渦電流探傷檢查的區間,進行渦電流探傷檢查,藉此可縮短檢查期間。According to the configuration of the above (4), the eddy current flaw detection of the pipe member 10 can be performed. Furthermore, according to the configuration of the above (4), the acquisition of the image of the inside of the pipe member 10 and the eddy current flaw detection inspection of the pipe member 10 can be performed simultaneously, so that the inspection period can be shortened. Furthermore, according to the configuration of the above (4), the operator who performs the inspection observes the image of the inside of the pipe member 10, and the eddy current inspection is not performed in a section where it is judged from the image that the eddy current inspection is not necessary. From this image, it is possible to shorten the inspection period by judging the area in which the eddy current inspection is necessary, and performing the eddy current inspection.

(5)在幾個實施形態,上述(4)的構造中,被攝體光的射入部62,是安裝在:沿著索狀體30的長度方向配置在比渦電流探傷用的感測器70還靠索狀體30之前端側的氣體承受部40為佳。(5) In some embodiments, in the structure of the above (4), the incident portion 62 of the subject light is attached to a sensor for eddy current flaw detection arranged along the longitudinal direction of the cord-like body 30 The device 70 is preferably also close to the gas receiving portion 40 on the front end side of the cord-shaped body 30 .

根據上述(5)的構造,將被攝體光的射入部62沿著索狀體30的長度方向配置在比渦電流探傷用的感測器70還靠索狀體30的前端側,藉此在欲取得索狀體30之前方圖像的情況,可防止在管構件10的內部圖像拍到渦電流探傷用之感測器70的情況。According to the configuration of (5) above, the incident portion 62 of the subject light is arranged on the front end side of the cord-shaped body 30 along the longitudinal direction of the cord-shaped body 30 rather than the sensor 70 for eddy current flaw detection. In this case, when an image of the front of the cord-like body 30 is to be acquired, it is possible to prevent the sensor 70 for eddy current flaw detection from being captured in the image inside the pipe member 10 .
