本發明之至少一實施形態之管構件的檢查系統,是用來檢查管構件之管構件的檢查系統,具備:可***至管構件的檢查裝置、可對管構件供給氣體的氣體供給部。檢查裝置,具有索狀體與安裝於索狀體的氣體承受部。A pipe member inspection system according to at least one embodiment of the present invention is a pipe member inspection system for inspecting the pipe member, and includes an inspection device insertable into the pipe member, and a gas supply portion capable of supplying gas to the pipe member. The inspection device includes a cord-shaped body and a gas receiving portion attached to the cord-shaped body.
Description
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.

FIG. 1 is a schematic diagram showing the overall structure of an
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
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
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
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

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
(渦電流探傷感測器70)
渦電流探傷感測器70,是用來在管構件10的內部進行渦電流探傷的感測器,含有檢測線圈。在幾個實施形態,可藉由渦電流探傷感測器70來檢測管構件10之腐蝕薄化。在幾個實施形態,於渦電流探傷感測器70,連接有後述的複數個訊號纜線118。
在幾個實施形態,渦電流探傷感測器70,是沿著索狀體30之長度方向配置在比攝影機單元60還靠索狀體30之基端側。
又,將攝影機單元60與渦電流探傷感測器70沿著索狀體30的長度方向分開配置為佳。藉此,可抑制攝影機單元60之雜訊對渦電流探傷感測器70的檢測訊號造成影響的情況、以及渦電流探傷感測器70之交變磁場等對攝影機單元60的圖像訊號造成影響的情況。(Eddy current flaw detection sensor 70)
The eddy current flaw detection sensor 70 is a sensor for performing eddy current flaw detection inside the
(索狀體30)
幾個實施形態的檢查裝置110,具有索狀體30與安裝於索狀體30的氣體承受部40。
索狀體30,是沿著管構件10的長度方向延伸的纜線狀構件,與攝影機單元60和渦電流探傷感測器70相較之下具有充分大的長度。且,索狀體30,是含有柔軟性優異的材料來形成,在檢查裝置110***至管構件10之際,可因應管構件10的形狀來柔軟地變形。(cord 30)
The
為了方便說明,索狀體30之中,將沿著索狀體30的長度方向比渦電流探傷感測器70還靠索狀體30之基端側的索狀體30稱為第1索狀體30a,將沿著索狀體30的長度方向比渦電流探傷感測器70還靠索狀體30之前端側的索狀體30稱為第2索狀體30b。
圖3A是圖2之索狀體30的A-A剖面圖,示意表示第1索狀體30a的剖面。圖3B是圖2之索狀體30的B-B剖面圖,示意表示第2索狀體30b的剖面。第1索狀體30a,具備:配置於中心部的攝影機纜線64、設在攝影機纜線64之徑方向外側的複數個訊號纜線118、設在複數個訊號纜線118之徑方向外側的保護層120。第2索狀體30b,具備攝影機纜線64與保護層120。For convenience of description, among the cord-shaped
攝影機纜線64,含有複數個訊號纜線,其用來將攝影機單元60之攝影元件所攝影之圖像的圖像訊號傳達至圖像記錄裝置230,為了方便,在圖3A及圖3B,是將攝影機纜線64的剖面予以簡略化。The
訊號纜線118,含有訊號纜線(例如同軸纜線),其用來傳達探傷感測器112與解析裝置200(參照圖1)之間的各種訊號,配置成包圍攝影機纜線64。The
保護層120,是由PVC等之絕緣性材料所形成,保護配置在內側的攝影機纜線64及訊號纜線118。The
又,在幾個實施形態,攝影機纜線64之複數個訊號纜線的各個、以及訊號纜線118的各個,是以可分辨出各個訊號纜線的方式,互相以由不同的配色來著色的外皮來包覆為佳。
且,在幾個實施形態,索狀體30,含有用來負擔對索狀體30作用之張力的受拉構件為佳。該受拉構件,例如含有由不銹鋼等之金屬材料所成的線材,其表面被聚氨酯等之皮膜所包覆為佳。In addition, in several embodiments, each of the plurality of signal cables of the
(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
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
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
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
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
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
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
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
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
(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

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
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

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
(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
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
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
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
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
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
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
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
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
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
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).
