201206816 六、發明說明： 【發明所屬之技術領域】 本發明係關於具備有藉由來自電池的供電而行駛，被 使用在貨櫃等的貨物的裝卸或裝貨的輪胎式起重機（ Rubber Tired Crane)的起重機系統。 本案係根據2010年6月8日在日本所申請的特願2010-131052號來主張優先權，在此沿用其內容。 【先前技術】 在作爲暫時集積貨櫃的場所的貨櫃場設有起重機系統 ，其使用一面沿著設在路面的複數行駛通道行駛，一面進 行貨櫃的裝卸或裝貨的場地起重機。而以場地起重機而言 ，大部分使用具有門型形狀且利用輪胎來進行行駛的輪胎 式門型起重機的所謂的RTG( Rubber Tired Gantry Crane )° 在該RTG係有藉由自動駕駛而沿著行駿通道行駛者。 此時，RTG裝備磁氣感測器，沿著行駛通道舖設由磁性體 所構成的地上導引線。接著’藉由磁氣感測器來檢測地上 導引線的磁氣，藉此檢測RTG的位置’來控制離地上導引 線的偏移。藉此，使RTG沿著地上導引線行駛。 此外，由於近年來的環保意識高漲’以11>1<3的驅動方 式而言，電動式備受矚目。由如上所示之觀點來看，裝備 電池作爲驅動源，由沿著行駛通道而設的供電線接收電力 而將電池進行充電之所謂的地上供電式RTG不斷在開發（ 201206816 參照例如專利文獻1 )。專利文獻1所記載的RTG係如其第 4圖所示，對作爲設在行駛通道上的通電部的剛體架空線 (主供電軌道8)，由橫向推碰設在RTG的集電裝置2 ’藉 此進行地上供電。 〔先前技術文獻〕 〔專利文獻〕 〔專利文獻1〕日本特開2009-242101號公報 【發明內容】 (發明所欲解決之課題） 但是，專利文獻1所記載之習知之具備有RTG的起重 機系統中，係有如下所示之問題。例如，設在行駛通道上 的剛體架空線（主供電軌道8 )係如其第3圖所示形成爲屬 於通電部的4條供電軌道露出在外部的狀態。因此，會有 作業者碰觸到供電軌道而觸電的危險性。 此外，習知之具備有RTG的起重機系統係藉由自動駕 駛，RTG沿著行駛通道進行行駛。此時，因在自動駕駛時 所產生的距離或角度的偏移，在行駛通道的寬度方向會發 生RTG若干蛇行。在此，專利文獻1所記載的RTG係如其第 6圖所示具備有支持集電裝置2的縮放儀狀的伸縮裝置3。 可藉由使該伸縮裝置3作伸縮，將集電裝置2的位置調整爲 行駛通道的寬度方向。藉由如上所示之構成，即使在RTG 由某一行駛通道朝相鄰接的其他行駛通道移動的情形下， 201206816 亦可藉由調整伸縮裝置的伸縮，將集電裝置2相對主供電 軌道8確實推碰。但是，該伸縮裝置3係如上所述並無法處 理在RTG行駿中所發生的蛇行，而會有集電裝置2與主供 電軌道8的接觸不充分的情形》 此外，RTG係以輪胎來進行行駛，因此因輪胎變形而 在鉛直方向亦會發生若干沈陷。但是，在專利文獻1所記 載的RTG中，無法處理朝該鉛直方向（上下方向）的沈陷 ，而會有集電裝置2與主供電軌道8的接觸不充分的情形。 本發明係考慮到如上所示之情形而硏創者，其目的之 一在提供一種作業人員碰觸到供電線而觸電的危險性較低 之具備有輪胎式起重機的起重機系統。此外，本發明之目 的之一在提供一種可以簡化構成來抵消因輪胎行駛所造成 之朝行駛通道的寬度方向的蛇行或朝鉛直方向的沈陷等輪 胎式起重機的位置偏移的起重機系統。 (解決課題之手段） 爲達成上述目的，本發明係採用以下之構成》亦即， 本發明之起重機系統係具備有以下構成。輪胎式起重機。 在輪胎式起重機的行駛路徑的側部，沿著行駛路徑配置， 在其中一面露出導體的供電線。被設在輪胎式起重機，在 輪胎式起重機之供電線側中與供電線相對應的位置，以可 朝前述行駛路徑的寬度方向移動的方式而設的集電子台車 。以可與供電線作電性連接的方式而設的集電子。被設在 前述集電子台車，以可朝與前述供電線的其中一面接近或 201206816 離開的方向移動的方式支持前述集電子的支持機構。 藉由如上所示之構成，藉由使集電子台車朝行駛路徑 的寬度方向移動，並且藉由支持機構而使集電子朝與供電 線的其中一面近接的方向移動，藉此可使集電子抵接於供 電線。 前述供電線亦可在下面露出導體。 藉由如上所示之構成，僅在供電線的下面露出導體， 在其他的面未露出導體，因此可防止作業人員接觸到導體 而觸電的情形。 前述集電子台車亦可藉由沿著前述行駛路徑的寬度方 向而朝前述輪胎式起重機的側方延伸的軌道予以支持。 藉由如上所示之構成，藉由簡化構成，可將集電子台 車在接近於輪胎式起重機的供電線之側，以可朝行駛路徑 的寬度方向移動的方式而設。 前述集電子台車亦可藉由前述軌道以可上下移動且可 水平移動的方式予以支持。 藉由如上所示之構成，即使在輪胎式起重機發生朝向 行駛通道的寬度方向的蛇行或朝向鉛直方向的沈陷的情形 下，亦可藉由使集電子台車上下移動或水平移動，而將該 等蛇行或沈陷抵消。 此外，上述起重機系統亦可具備有上下方向導引板與 寬度方向導引板。前述上下方向導引板係沿著前述供電線 ，與前述集電子台車的一部分相接觸而將前述集電子台車 朝上下方向導引。前述寬度方向導引板係沿著前述供電線 -8- 201206816 而與前述集電子台車的一部分相接觸，將前述集電子台車 朝前述行駛路徑的寬度方向導引。 藉由如上所示之構成，藉由上下方向導引板與寬度方 向導引板，使集電子台車導引至原本應通過的軌道。藉此 ，無關於輪胎式起重機的蛇行或沈陷，均可使集電子確實 抵接於供電線的其中一面。 前述寬度方向導引板亦可在沿著前述輪胎式起重機的 行駛方向而在比前述上下方向導引板更爲前述行駛方向的 後方（上游側），開始前述集電子台車的導引。 (發明之效果） 藉由本發明，可提供一種作業人員碰觸到供電線而觸 電的危險性低的起重機系統。此外，可提供一種可藉由簡 化構成來抵消因輪胎式起重機的行駿所造成之朝行駛通道 的寬度方向的蛇行或朝鉛直方向的沈陷，而可使集電子確 實抵接供電線之其中一面的起重機系統。 【實施方式】 以下參照圖示，說明本發明之實施形態。首先，說明 本發明之第1實施形態之具備有輪胎式起重機之起重機系 統之構成。第1圖係顯示本實施形態之具備有複數台輪胎 式起重機（自走式裝置）的起重機系統1的槪略斜視圖。 起重機系統1係具備有複數個：行駛通道R (行駛路徑）、

道滑動。接著，在上導引軌道對131係如前所述架設有2個 滑動限制構件132»藉此，集電子台車134係在台車本體 1342與2個滑動限制構件I32相接觸爲止的範圍內，亦即2 個滑動限制構件I32之間，容許沿著上導引軌道對131滑動 -15- 201206816 。藉由該構成，集電子台車134係朝向起重機本體11的寬 度方向的內側及外側而在預定的範圍滑動。集電子台車 134所滑動的方向亦可爲水平方向。此外，如第6圖所示’ 台車本體1 342係使各長穴1 342a的橫寬形成爲比上導引軌 道對131的橫寬稍大，在各長穴1 342a被插通上導引軌道對 131。藉此，台車本體1342係容許朝長穴13 42 a的長邊方向 不穩與朝台車本體13 42的寬度方向不穩等二者。在此，長 穴1 342a的長邊方向亦可爲鉛直方向亦即上下方向。此外 ，台車本體1 342的寬度方向亦可與RTG10的行駛方向或水 平方向呈平行。其中，下滑件對1 347之構成及功能與上滑 件對1 346相同，因此在此省略說明。 第3圖所示之上部集電子單元1348與下部集電子單元 1 3 49係藉由與第2圖所示之供電單元2 0相連接而受電。在 此，第7圖係上部集電子單元1 348的動作說明圖》上部集 電子單元13 48係具備有：集電子13 52、及以可上下移動的 方式支持該集電子1352的支持機構1353。接著，支持機構 1353係具有：支柱1353a、臂部構件1353b、按壓用滾筒 1 3 53c、及彈壓彈簧1 3 53d。支柱1 3 53a係被固定在集電子 台車134的台車本體1342。臂部構件1353b係藉由該支柱 1353a而以可旋動的方式支持基端而在前端固定有集電子 1352»按壓用滾筒1353c係以可旋轉的方式被軸支在臂部 構件1353b的長邊方向的中間部。彈壓彈簧1353d係一端被 固定在支柱1353a，另一端被固定在臂部構件1353b。 上部集電子單元1 348係當遠離構成供電單元20的後述 -16- 201206816 絕緣架空線292時，臂部構件1 3 53b由彈壓彈簧1 3 53d受到 拉伸力。藉此，集電子1 3 52形成爲被上舉至比絕緣架空線 2 92更爲上方的狀態。接著，若隨著RTG10的行駛，上部 集電子單元1348接近絕緣架空線292時，固定在供電單元 20的預定部位而設的棒狀升降舵210會與按壓用滾筒1353c 相接觸。該升降舵210係具有以朝向RTG10的行駛方向下 降的方式呈傾斜的形狀。因此，被該升降舵210的傾斜導 引而壓低按壓用滾筒13 53 c，藉此臂部構件1 3 53b以使集電 子135 2下降的方式進行旋動。藉此，集電子135 2下降至比 絕緣架空線292爲更低的位置，由絕緣架空線292的一端側 被插入至其內部。其中，下部集電子單元1 3 49的構成與上 部集電子單元1 348相同，因此在此省略說明。 如上所述，藉由彈壓彈簧1353d來彈壓支持集電子 1 3 52的臂部構件1 3 53b。藉此，減小集電子1 3 52碰到升降 舵210時的撞撃，而可防止集電子1352的損傷。此外，若 將集電子13 52的角部形成爲曲面狀，可更加緩和前述撞撃 。此外，若將升降舵210的材質形成爲低摩擦的材質，例 如鐵氟龍（註冊商標），可減低與集電子1 352之間的摩擦 ，而可防止集電子1352的磨損。此外，如第17圖所示，亦 可將升降舵21 0的形狀形成爲包含所謂的緩和曲線，亦即 由直線慢慢變化成預定圓弧曲線的曲率的曲線的形狀。此 時係可減低集電子1 3 52接觸到升降舵210時的撞撃而防止 集電子1352等的損傷，並且可縮短升降舵210的長度。此 外，在本實施形態中，係藉由升降舵2 1 0來壓低按壓用滾 •17- 201206816 筒1 3 53 c而使集電子1 3 52下降，但是亦可取代此，而藉由 升降舵210來直接按壓集電子1352而壓低。但是，若如本 實施形態般按壓按壓用滾筒1353c時，係可防止使用銅等 材料所形成的集電子1352因與升降舵210的滑動而磨損的 情形。 其中，在如以上所示所構成的RTG10中，起重機本體 1 1的形狀、輪胎列12的數量或位置、電氣室14或電池15的 設置位置、懸掛裝置16的構成等可作適當設計變更，而非 限定於本實施形態。此外，在本實施形態中係使RTG 10僅 沿著某1條行駿通道R行駛，但是亦可將RTG 10朝相鄰接的 行駛通道R移動。 前述供電單元20係對RTG 10供給電力。如第1圖所示

向彼此相對向。一對滾筒導引板26亦可以分別朝鉛直方向 突出的方式而設。 定位板27係在一對滾筒導引板26之間由水平片24的內 側面突出而設。定位板27亦可以朝鉛直方向突出的方式而 設。 行駛滾筒用架台28係由供電裝置本體25的上部朝向側 -19- 201206816 方突出而設。亦即，行駛滾筒用架台28係由供電裝置本體 25的內側面朝向行駛通道r的寬度方向的內側突出。 上部架空線單元29及下部架空線單元30係被設在比供 電裝置本體25中的行駛滾筒用架台28更爲下方的位置。 —對滾筒導引板26係將第3圖所示之上導引滾筒對 1 343及下導引滾筒對1 344朝預定方向導引。例如，一對滾 筒導引板26係將上導引滾筒對1343及下導引滾筒對13 44朝 RTG10的行駛方向導引。如第8圖所示，各滾筒導引板26 係在長邊方向的中間部呈曲折的細長板狀的構件。如上所 示之2枚滾筒導引板26係在朝上下的水平片24的內側面豎 立的狀態下分別予以固定，隔著預定間隔彼此相對向。各 滾筒導引板26係以由供電裝置本體25的寬度方向的一端部 達至供電裝置本體25的寬度方向的中央部爲止的方式延伸 。在此，供電裝置本體25的寬度方向亦可與RTG10的行駛 方向呈平行。此外，2枚滾筒導引板26的間隔係由供電裝 置本體25的寬度方向的一端部朝向寬度方向的中央部慢慢 變窄，之後形成爲一定的間隔。藉此，2枚滾筒導引板26 係在俯視下呈大致Υ字形狀。其中，如第18圖所示，亦可 將2枚滾筒導引板26的間隔慢慢變窄的部分的形狀形成爲 所謂的緩和曲線。此時，可減低上導引滾筒對1 3 43或下導 引滾筒對1 344接觸到滾筒導引板26時的撞撃力。 定位板27係藉由第3圖所示之上導引滾筒對13 43及下 導引滾筒對1 344予以夾持》如第8圖所示’該定位板27係 細長平板狀的構件，其長度係比供電裝置本體25的橫寬稍 -20- 201206816 短。定位板27的厚度係與形成在第4圖所示之上導引滾筒 對1 343之間的間隙1351的寬幅爲相同程度。定位板27係在 上下的水平片24的內側面中，在彼此相對向的滾筒導引板 26之間的位置呈豎立的狀態下予以固定。接著，該定位板 27係以由供電裝置本體25的寬度方向的中央部附近的2枚 滾筒導引板26的間隔爲一定的區域，達至供電裝置本體25 的寬度方向的端部爲止的方式延伸。其中，該定位板27的 材質亦可爲低摩擦的材質，例如鐵氟龍（註冊商標）。此 時，減低與上導引滾筒對1 343或下導引滾筒對1344之間的 摩擦，而可防止上導引滾筒對1 343或下導引滾筒對1344的 磨損。此外，若在定位板27與上導引滾筒對13 43或下導引 滾筒對13 44之間塗佈潤滑油，可更加防止上導引滾筒對 1 3 43或下導引滾筒對1 344的磨損。 行駛滾筒用架台28係發揮作爲第3圖所示之行駛滾筒 1 3 45之行駿路面的作用。如第8圖所示，該行駛滾筒用架 台28係細長平板狀的構件，在平行部28a的一端部設有斜 向傾斜的傾斜部28b。平行部28 a係設爲與傾斜部28b相比 更爲長形。行駛滾筒用架台28係在供電裝置本體25的內側 面亦即水平片24所突出之側的面的上部，在呈豎立的狀態 下被固定，藉此朝水平方向突出。接著，該行駛滾筒用架 台28係以由供電裝置本體25的寬度方向的中央部達至寬度 方向的一方端部爲止的方式延伸。其中，如第19圖所示， 若將行駛滾筒用架台28的傾斜部28b的形狀形成爲所謂的 緩和曲線，可減低行駛滾筒1 345接觸到傾斜部28b時的撞 -21 - 201206816 撃力》 上部架空線單元29與下部架空線單元30係發揮作爲連 接第7圖所示之集電子1 3 52的連接端子的作用。如第8圖所 示，上部架空線單元2 9係具備有：被固定在供電裝置本體 25的內側面的板狀安裝用托架291、及被安裝在該安裝用 托架291之下面的2條絕緣架空線（供電線）292。其中， 集電子台車134係被設在與RTG10中的絕緣架空線292相對 應的位置，亦即接近RTG 10之架空線292之側的側部。絕 緣架空線292係沿著行駛通道R被配置在行駛通道R的側部 。若受電裝置13與供電裝置23在RTG10的行駛方向中相對 移動，第3圖所示之行駛滾筒1 345係由第8圖所示之傾斜部 28b載置到行駛滾筒用架台28的上面，而在平行部28b的上 面移動。安裝用托架291係如上所示在行駛滾筒1 345接觸 到行駛滾筒用架台28的水平區域的狀態下，以使第8圖所 示之絕緣架空線292位於與第3圖所示之上部集電子單元 1 348相對應的位置的方式，被固定在供電裝置本體25。 其中’下部架空線單元30亦與上部架空線單元29同樣 地，具備有安裝用托架301及2條絕緣架空線302，其構成 及功能與上部架空線單元29相同，因此省略其說明。 第9圖係顯示絕緣架空線292的槪略斜視圖。絕緣架空 線292係具有·作爲通電部而發揮功能的導線（導體） 2921、及覆蓋該導線2921的絕緣包覆件2922。導線2921係 藉由具有電氣傳導性且電阻小的材料，例如鐵、銅、或鋁 等所形成。導線2921若對雨等的耐腐蝕性較高，則更加合 -22- 201206816 適。如第9圖所示，該導線292 1係在與其長邊方向呈正交 的剖面，具有供第7圖所示之集電子1352相嵌合的溝部 2921 a。此外，導線292 1係具有與絕緣包覆件2922相扣合 的凸部2921b。如上所示所構成的導線2921係對第1圖所示 之供給配線路22作電性連接。 絕緣包覆件2922係防止在貨櫃場Y進行作業的人員接 觸到導線2921而觸電的情形。該絕緣包覆件2922係由具有 電氣絕緣性的材料，例如樹脂或陶瓷等所構成的中空殼體 。如第9圖所示，絕緣包覆件2922係在與其長邊方向呈正 交的剖面，在其上部形成有凹部2922a。此外，在絕緣包 覆件2922的下部形成有開口部2922b。如上所示所構成的 絕緣包覆件2922係在其內部被嵌入導線2921，導線2921的 凸部2921b與絕緣包覆件2922的凹部2922 a相扣合而扣止" 藉此，透過絕緣包覆件2922的開口部292 2b，導線2921露 出至外部。此外，藉由凸部2921b與凹部2922a的相扣合， 導線2921不會由開口部2922b脫落而被保持在絕緣包覆件 2922的內部》 接著，說明本發明之第1實施形態之RTG 10的作用及 效果。首先，使用第10圖至第12圖，說明朝RTG10的行駛 通道R的寬度方向的定位。如前所述，若藉由自動駕皸來 實現沿著行駛通道R的行駛時，由於在自動駕駛時所發生 的距離或角度的偏移，會在行駛通道的寬度方向發生稍微 的蛇行。因此，必須不會受到該蛇行影響，使屬於構成受 電裝置13的構件之一的集電子1352，相對屬於構成供電裝 23- 201206816 置23之構件之一的絕緣架空線292確實接觸，而使該等作 電性連接。因此，在本發明之RTG10中，在將集電子1352 連接於絕緣架空線292之前，進行對RTG10的行駛通道R的 寬度方向的定位。其中，在以下說明中係僅針對上導引滾 筒對1 343的定位動作加以說明，但是針對下導引滾筒對 13 44，亦進行與上導引滾筒對13 43同樣的定位動作。 若在沿著行駛通道R行駛的RTG10發生蛇行，會在 RTG10所通過的軌道發生行駿通道R的寬度方向中的稍微 偏移。在第10圖（a)中，行駛通道R的寬度方向係與定位板 27所延伸的方向呈正交的方向。在第10圖（a)中以虛線表示 若在RTG10發生蛇行時，集電子台車134的上導引滾筒對 1 3 43所欲通過的軌道。此外，在圖中以一點鏈線表示若沒 有蛇行時，原本RTG10應通過的軌道。如上所示，若在 RTG10發生蛇行，與原本應通過的軌道（一點鏈線）相比 較，集電子台車134的上導引滾筒對13 43所欲通過的軌道 (虛線）係朝與RTG 10的行駛方向呈正交的方向發生稍微 偏移。 此時，如第10圖（b)所示，朝向RTG10的行駛方向而位 於前方的上導引滾筒對13 43係在2枚滾筒導引板26的間隔 慢慢變大的區域中與滾筒導引板26相接觸。如此一來，該 上導引滾筒對13 43係開始沿著滾筒導引板26移動。在此， 如前所述，屬於構成第6圖所示之集電子台車134之構件之 —的台車本體13 42係容許對長穴13 42 a的寬度方向不穗。 其中，長穴1 342a的寬度方向亦可爲與RTG10的行駿方向 -24- 201206816 亦即定位板27呈平行。此外，此時，若上導引滾筒對1343 開始沿著滾筒導引板26移動，藉由上導引滾筒對1 343由滾 筒導引板26所受到的力，如第10圖（c)所示，在台車本體 1 342係會發生稍微傾斜。 RTG10係由第10圖（c)的狀態更加朝前方行駛。如此一 來，如第1 1圖（a)所示，位於RTG 10的行駛方向的前方的上 導引滾筒對1 3 43係在與滾筒導引板26相接觸的狀態下，進 入至2枚滾筒導引板26的間隔爲一定的區域。接著，在位 於該行駛方向的前方的上導引滾筒對1343之間形成有間隙 1351。藉由定位板27進入至該間隙1351，上導引滾筒對 13 43係形成爲藉由各滾筒本體13 43 a來夾持定位板27的狀 態。 RTG10係由第1 1圖（a)的狀態更加朝前方行駛。如此一 來，如第1 1圖（b)所示，位於RTG1 0的行駛方向的後方的上 導引滾筒對1 3 43會在2枚滾筒導引板26的間隔慢慢變大的 區域中與滾筒導引板26相接觸。如此一來，該上導引滾筒 對1 3 43亦開始沿著滾筒導引板26移動。接著，隨著上導引 滾筒對1 343沿著滾筒導引板26而朝RTG10的行駛方向的前 方移動，台車本體1 342相對行駛方向的傾斜會慢慢變小。 RTG 10係由第11圖（b)的狀態更加朝前方行駛。如此一 來，位於RTG 10的行駛方向的後方的上導引滾筒對1343亦 在與滾筒導引板26相接觸的狀態下，進入至2枚滾筒導引 板26的間隔爲一定的區域。此時，台車本體1342亦可爲與 RTG10的行駛方向呈平行的狀態。接著，位於RTG10的行 -25- 201206816 駛方向的後方的上導引滾筒對1 3 43亦如第1 1圖（c)所示，在 各滾筒本體1 343a之間形成有間隙1351。藉由定位板27進 入至該間隙1351’上導引滾筒對1343係形成爲藉由各滾筒 本體13 43 a來夾持定位板27的狀態。藉此形成爲上導引滾 筒對1343所通過的軌道與原本應通過的軌道相一致的狀態 。藉由以上，朝集電子台車134的行駛通道R的寬度方向的 定位即完成。 RTG 10係由第1 1圖（c)的狀態更加朝前方行駛。如此一 來，如第12圖（a)所示，位於RTG10的行駛方向的前方的集 電子1 3 52即由絕緣架空線292的長邊方向一端側被插入至 內部。集電子1352係構成上部集電子單元1348的構件之一 。之後，如第12圖（b)所示，位於RTG10的行駛方向的後方 的集電子1352亦被插入在絕緣架空線292的內部。接著， 在上部集電子單元1 348的全體被插入在絕緣架空線292的 內部的時點，RTG 10係停止行駛。在該狀態下，開始由供 電單元20對RTG10供給電力。其中，在由第11圖（c)的狀態 達至第12圖（a)的狀態之期間，進行對集電子台車134的上 下方向的定位。 接著使用第13圖至第16圖，說明朝RTG 10的上下方向 的定位。如前所述，RTG 10意指輪胎式起重機10，以輪胎 列12進行行駛。因此，因起重機本體11等的重量而在輪胎 列12發生變形，藉此在RTG 10係會有在鉛直方向（上下方 向）發生稍微沈陷的情形。因此，必須不會受該沈陷影響 ，而使構成受電裝匱13的集電子1352相對構成供電裝置23 26- 201206816 的絕緣架空線2 92作確實連接。因此，在本實施形態之 RTG10中，係將對行駛通道R的寬度方向的定位，相較於 進行上下方向的定位的位置，而在RTG 10的行駛方向的後 方（上游側）開始。其中，與本實施形態相反地，亦可將 上下方向的定位，相較於進行行駛通道R的寬度方向的定 位的位置，而在RTG10的行駛方向的後方開始。此外，亦 可同時進行行駛通道R的寬度方向的定位與上下方向的定 位。 若在沿著行駛通道R行駛的RTG10發生沈陷時，在 RTG 10所通過的軌道會發生鉛直方向中的稍微偏移。在第 13圖（a)中以虛線表示集電子台車134的行駛滾筒13 45所欲 通過的軌道。此外，在圖中以一點鏈線表示若爲沒有沈陷 時，原本應通過的軌道。如上所示，與原本應通過的軌道 (一點鏈線）相比較，若在RTG 1 0發生沈陷，集電子台車 134的行駿滾筒1 345所欲通過的軌道（虛線）係會朝下方 向發生稍微偏移。其中，在該狀態下’集電子台車134係 藉由由下方接觸上滑件對13 46的上導引軌道對131、及由 下方接觸下滑件對1347的下導引軌道對133’而由下方被 支持。 此時，位於RTG 10的行駛方向中的前方的行駛滾筒 1 34 5係與行駛滾筒用架台28中的傾斜部28b相接觸，而開 始沿著該傾斜部28b移動。在此’如前所述在構成第6圖所 示之集電子台車134的台車本體1342係容許對長穴1342a的 長邊方向不穩。因此，若行皲滾筒1 3 45開始沿著行駛滾筒 -27- 201206816 用架台28移動時，行駿滾筒1345會由行駛魚筒用架台28受 力。藉由該力，如第13圖（b)所示，台車本體1 342係形成爲 行駛方向中的前方上舉而呈傾斜的狀態。另一方面，由 RTG 10的起重機本體11延伸的上導弓|軌道對131、下導弓| 軌道對133、及滑動限制構件132係維持水平狀態。上滑件 對1346係構成集電子台車134的構件之一。因此，如第13 圖（b)所示，在台車本體1 342呈傾斜的狀態下，位於RTG10 的行駛方向的後方的上滑件對1346係維持與上導引軌道對 131相抵接的狀態，位於行駛方向的前方的上滑件對1346 係遠離上導引軌道對131。藉此，集電子台車13 4係藉由行 駛滾筒用架台28來支持位於RTG 10的行駛方向中的前方的 部分。另一方面，集電子台車134係形成爲使藉由位於 RTG10的行駛方向中的後方的部分被上導引軌道對131與 下導引軌道對133所支持的狀態。 在此，第16圖係說明進行集電子台車134的上下方向 中的定位時的台車本體13 42及上導引滾筒對13 43的動作的 圖。如第13圖（b)所示，若形成爲台車本體1 3 42的行駛方向 的前方的部分上舉而呈傾斜的狀態時，被設在台車本體 13 42的滾筒支持片1341會由在第16圖中以二點鏈線所示位 置朝向以實線所示位置上升。在此，如前所述，上導引滾 筒對1343的旋轉支軸1343b係以可藉由滑動軸承1341b與滑 動軸承1341e而朝軸向滑動的方式予以支持。因此，即使 滾筒支持片1341上升，亦使滑動軸承1341b與滑動軸承 1341e沿著旋轉支軸1 343b移動，上導引滾筒對1 343並不會 -28- 201206816 朝上下方向移動。在朝集電子台車134的上下方向的定位 時，係形成爲上導引滾筒對1 343與滾筒導引板26或定位板 27相接觸的狀態。即使在該狀態下，上導引滾筒對1 343並 不會朝上下方向移動，因此在滾筒支持片1341上升時，不 會有上導引滾筒對1343與滾筒導引板26或定位板27滑動而 磨損的情形。 RTG10係由第13圖（b)所示狀態更加行駛。如此一來， 如第14圖（a)所示，位於RTG 10的行駛方向中的前方的行駛 滾筒13 45會由行駛滾筒用架台28的傾斜部28b而載置至平 行部28a。另一方面，位於RTG10的行駛方向中的後方的 行駛滾筒1 345亦與傾斜部28b相接觸，開始沿著傾斜部28b 移動。伴隨於此，台車本體13 42係連RTG10的行駛方向中 的後方側的部分亦慢慢上舉。藉此，台車本體1 3 42的上端 及下端形成爲與行駛通道R的路面呈平行（水平）。接著 ，構成集電子台車134的上滑件對1 346係形成爲如下狀態 。亦即，如第14圖（b)所示，位於RTG10的行駛方向中的前 方的滑件對134 6與位於後方的上滑件對13 46之二者會由上 導引軌道對131離開。藉此，集電子台車13 4係形成爲藉由 行駛滾筒用架台28來支持位於RTG 10的行駿方向中的前方 的上滑件對1 346與位於後方的上滑件對1 346之二者的狀態 〇 接著，位於RTG10的行駛方向中的後方的行験滾筒 1 345亦由行駿滾筒用架台28的傾斜部28b而載置到平行部 28a。如此一來，行駛滾筒1 345所通過的軌道形成爲與原 -29- 201206816 本應通過的軌道相一致的狀態，集電子台車134的上下方 向中的定位即完成。之後，若RTG 1 0更加行駛時，如第1 5 圖（a)所示，構成上部集電子單元1 348的集電子1 3 52即由絕 緣架空線2 92的長邊方向的一端被插入在內部。在此時點 ，RTG 10係停止行駛，由供電單元20開始電力的供給。 其中，在上述實施形態中所示之各構成構件的各形狀 或組合、或動作順序等爲一例，在未脫離本發明之主旨的 範圍內，可根據設計要求等而爲各種變更。 例如，在上述實施形態中係針對具備有輪胎式起重機 裝置的起重機系統加以說明。但是，本發明並非限定於起 重機系統，可應用在例如對包括輪胎式起重機裝置的自走 式裝置供電的供電系統。亦即，亦可將具備有上述絕緣架 空線292、集電子台車134、集電子1352及支持機構（支柱 1353a、臂部構件1353b、按壓用滾筒1353c、彈壓彈簧 1 3 53 d )的供電系統設在輪胎式起重機以外的自走式裝置 。藉由該供電裝置，在輪胎式起重機以外的自走式裝置中 ，亦可在對裝置供電時，將裝置的位置偏移抵消。 以上說明本發明之較佳實施形態，惟本發明並非限定 於上述之實施形態。在未脫離本發明之趣旨的範圍內，可 爲構成的附加、省略、置換、及其他變更。本發明並非藉 由前述說明予以限定，而僅受所附申請專利範圍所限定。 (產業上可利用性） 爲具備有以下構成的起重機系統。輪胎式起重機。沿 -30- 201206816 著前述輪胎式起重機的行駛路徑配置，在其中一面露出導 體的供電線。被設在前述輪胎式起重機，在與前述供電線 相對應的位置，以可朝前述行駿路徑的寬度方向移動的方

In the case of a site crane, the so-called RTG (Rubber Tired Gantry Crane) of a tire type gantry crane having a gate shape and using a tire to travel is used in the RTG system. Jun channel traveler. At this time, the RTG is equipped with a magnetic gas sensor, and an above-ground guide wire composed of a magnetic body is laid along the traveling path. Then, the magnetic gas of the ground lead is detected by the magnetic gas sensor, thereby detecting the position of the RTG to control the offset of the guide wire from the ground. Thereby, the RTG is driven along the ground guide line. In addition, due to the high environmental awareness in recent years, the number is 11>1 < In terms of the driving method of 3, The electric type is highly regarded. From the point of view as shown above, Equipped with a battery as a driving source, A so-called above-ground power supply type RTG that receives power by receiving power from a power supply line provided along a travel path is being developed (201206816, for example, Patent Document 1). The RTG described in Patent Document 1 is as shown in Fig. 4, For the rigid body overhead line (main power supply rail 8) as the energizing portion provided on the traveling path, Ground power is supplied by laterally pushing the current collecting device 2' provided at the RTG. [Prior Art Document] [Patent Document 1] [Patent Document 1] JP-A-2009-242101 SUMMARY OF INVENTION [Problems to be Solved by the Invention] However, In the conventional crane system including the RTG described in Patent Document 1, There are problems as shown below. E.g, The rigid body overhead line (main power supply rail 8) provided on the traveling path is formed such that the four power supply rails belonging to the energizing portion are exposed to the outside as shown in Fig. 3. therefore, There is a risk that the operator will hit the power rail and get an electric shock. In addition, It is known that the crane system with RTG is driven by automatic driving. The RTG travels along the travel path. at this time, Due to the deviation of the distance or angle generated during automatic driving, There are several RTG snakes in the width direction of the driving path. here, The RTG described in Patent Document 1 includes a scaler-like expansion and contraction device 3 that supports the power collecting device 2 as shown in Fig. 6 .

In addition, The width direction of the trolley body 1 342 may also be parallel to the traveling direction or horizontal direction of the RTG 10. among them, The structure and function of the slider pair 1 347 is the same as that of the upper slider pair 1 346. Therefore, the description is omitted here. The upper collecting electron unit 1348 and the lower collecting electronic unit 1 3 49 shown in Fig. 3 are electrically connected by being connected to the power supply unit 20 shown in Fig. 2. here, Fig. 7 is an operation explanatory diagram of the upper collecting electronic unit 1 348. The upper set electronic unit 13 48 is provided with: Collecting electrons 13 52, The support mechanism 1353 of the integrated electronic unit 1352 is supported in a manner that can be moved up and down. then, Support organization 1353 has: Pillar 1353a, Arm member 1353b, Pressing roller 1 3 53c, And spring spring 1 3 53d.

The pressing roller 1353c is rotatably supported on the long side of the arm member 1353b. The middle part of the direction. One end of the spring 1853d is fixed to the pillar 1353a. The other end is fixed to the arm member 1353b. The upper collecting electronic unit 1 348 is away from the -16-201206816 insulated overhead line 292 which will be described later, which constitutes the power supply unit 20. The arm members 1 3 53b are subjected to a tensile force by the springs 1 3 53d. With this, The collecting electrons 1 3 52 are formed to be lifted up to a position higher than the insulated overhead wire 2 92. then, If you follow the RTG10, When the upper collecting electronic unit 1348 approaches the insulated overhead line 292, The rod-shaped elevator 210 provided at a predetermined portion of the power supply unit 20 is in contact with the pressing roller 1353c. The elevator 210 has a shape that is inclined so as to descend toward the traveling direction of the RTG 10. therefore, The pressing roller 13 53 c is pressed by the inclination of the elevator 210, Thereby, the arm members 1 3 53b are rotated to lower the current collector 135 2 . With this, The collector 135 2 drops to a lower position than the insulated overhead line 292. One end side of the insulated overhead wire 292 is inserted into the inside thereof. among them, The lower collecting electronic unit 1 3 49 has the same configuration as the upper collecting electronic unit 1 348. Therefore, the description is omitted here. As mentioned above, The arm member 1 3 53b that supports the collecting electrons 1 3 52 is biased by the biasing spring 1353d. With this, Reducing the impact when the collecting electrons 1 3 52 hit the elevator 210, It can prevent the damage of the electron collection 1352. In addition, If the corners of the collecting electrons 13 52 are formed into a curved shape, The above impact can be alleviated more. In addition, If the material of the elevator 210 is formed into a low friction material, For example, Teflon (registered trademark), Can reduce the friction between the set electrons 1 352, The wear of the collector 1352 can be prevented. In addition, As shown in Figure 17, The shape of the elevator 21 may also be formed to include a so-called mitigation curve. That is, the shape of a curve which is gradually changed from a straight line to a curvature of a predetermined arc curve. At this time, it is possible to reduce the impact when the collecting electrons 1 3 52 contact the elevator 210 and prevent the damage of the collecting electrons 1352 and the like. And the length of the elevator 210 can be shortened. In addition, In this embodiment, By pressing the elevator 2 1 0 to lower the pressing roller, 17-201206816, the tube 1 3 53 c, and lowering the collecting electrons 1 3 52, But it can also replace this, On the other hand, the elevator 210 directly presses the collecting electrons 1352 to be depressed. but, When the pressing roller 1353c is pressed as in the embodiment, This prevents the collection of electrons 1352 formed of a material such as copper from being worn by the sliding of the elevator 210. among them, In the RTG 10 constructed as shown above, The shape of the crane body 1 1 , The number or position of the tire rows 12, The setting position of the electric chamber 14 or the battery 15, The configuration of the suspension device 16 and the like can be appropriately changed.

E.g, A pair of roller guide plates 26 guide the upper guide roller pair 1343 and the lower guide roller pair 13 44 toward the traveling direction of the RTG 10. As shown in Figure 8, Each of the drum guide plates 26 is an elongated plate-shaped member that is meandered in the intermediate portion in the longitudinal direction. The two roller guide sheets 26 as shown above are fixed in a state in which they are erected toward the inner side surface of the upper and lower horizontal sheets 24, Oppose each other across a predetermined interval. Each of the drum guide plates 26 extends so that one end portion in the width direction of the power supply device main body 25 reaches the center portion in the width direction of the power feeding device main body 25. here, The width direction of the power supply unit body 25 may also be parallel to the traveling direction of the RTG 10. In addition, The interval between the two roller guide plates 26 is gradually narrowed from the one end portion in the width direction of the power supply device main body 25 toward the center portion in the width direction. It is then formed at a certain interval. With this, The two roller guide plates 26 have a substantially U shape in plan view. among them, As shown in Figure 18, The shape of the portion where the interval between the two roller guide plates 26 is gradually narrowed may be formed as a so-called easing curve. at this time, The impact force of the upper guide roller pair 1 3 43 or the lower guide roller pair 1 344 contacting the roller guide plate 26 can be reduced. The positioning plate 27 is held by the upper guide roller pair 13 43 and the lower guide roller pair 1 344 shown in Fig. 3, as shown in Fig. 8; the positioning plate 27 is an elongated flat member. The length is shorter than the horizontal width of the power supply unit body body -20-201206816. The thickness of the positioning plate 27 is the same as the width of the gap 1351 formed between the pair of guiding rollers 1 343 shown in Fig. 4. The positioning plate 27 is in the inner side of the upper and lower horizontal sheets 24, The position between the roller guide plates 26 opposed to each other is fixed in a state of being erected. then, The positioning plate 27 is a region in which the interval between the two roller guide plates 26 in the vicinity of the center portion in the width direction of the power supply device main body 25 is constant. It extends so as to reach the end portion of the power supply device main body 25 in the width direction. among them, The material of the positioning plate 27 can also be a low friction material. For example, Teflon (registered trademark). at this time, Decreasing the friction between the upper guide roller pair 1 343 or the lower guide roller pair 1344, The wear of the upper guide roller pair 1 343 or the lower guide roller pair 1344 can be prevented. In addition, If lubricating oil is applied between the positioning plate 27 and the upper guiding roller pair 13 43 or the lower guiding roller pair 13 44, The wear of the upper guide roller pair 1 3 43 or the lower guide roller pair 1 344 can be further prevented. The traveling roller gantry 28 functions as a road surface of the running roller 1 3 45 shown in Fig. 3 . As shown in Figure 8, The traveling roller table 28 is an elongated flat member. An inclined portion 28b that is inclined obliquely is provided at one end portion of the parallel portion 28a. The parallel portion 28a is formed to be longer than the inclined portion 28b. The traveling roller gantry 28 is on the inner side of the power supply device main body 25, that is, the upper surface of the surface on which the horizontal piece 24 protrudes. Fixed in an upright state, This is to protrude in the horizontal direction. then, The traveling roller table 28 extends so that the center portion in the width direction of the power feeding device main body 25 reaches one end portion in the width direction. among them, As shown in Figure 19, When the shape of the inclined portion 28b of the traveling roller gantry 28 is formed into a so-called easing curve, It is possible to reduce the collision when the traveling roller 1 345 comes into contact with the inclined portion 28b - 201206816 撃力 The upper overhead wire unit 29 and the lower overhead wire unit 30 function as connection terminals for connecting the collecting electrons 1 3 52 shown in Fig. 7 The role. As shown in Figure 8, The upper overhead line unit 2 9 series is equipped with: a plate-shaped mounting bracket 291 that is fixed to the inner side surface of the power supply device body 25, And two insulated overhead wires (power supply lines) 292 mounted under the mounting bracket 291. among them, The set electronic trolley 134 is disposed at a position corresponding to the insulated overhead wire 292 in the RTG 10. That is, near the side of the side of the overhead line 292 of the RTG 10. The insulated overhead line 292 is disposed along the traveling path R at the side of the traveling path R. If the power receiving device 13 and the power supply device 23 relatively move in the traveling direction of the RTG 10, The running roller 1345 shown in Fig. 3 is placed on the upper surface of the traveling roller stand 28 by the inclined portion 28b shown in Fig. 8. On the other hand, it moves above the parallel portion 28b. The mounting bracket 291 is in a state where the traveling roller 1 345 comes into contact with the horizontal area of the traveling roller stand 28 as described above. The insulating overhead wire 292 shown in Fig. 8 is located at a position corresponding to the upper collecting electron unit 1 348 shown in Fig. 3, It is fixed to the power supply unit body 25. Wherein the lower overhead line unit 30 is also the same as the upper overhead line unit 29, It has a mounting bracket 301 and two insulated overhead wires 302. The structure and function are the same as those of the upper overhead line unit 29, Therefore, the description thereof is omitted. Fig. 9 is a schematic oblique view showing the insulated overhead wire 292. The insulated overhead wire 292 has a wire (conductor) 2921 that functions as an energizing portion, And an insulating covering member 2922 covering the wire 2921. The wire 2921 is made of a material having electrical conductivity and low electrical resistance. Such as iron, copper, Or aluminum or the like formed. If the wire 2921 has high corrosion resistance to rain or the like, It is more -22-201206816. As shown in Figure 9, The wire 292 1 is in a cross section orthogonal to the longitudinal direction thereof. There is a groove portion 2921a to which the collector electrons 1352 shown in Fig. 7 are fitted. In addition, The wire 292 1 has a convex portion 2921b that is engaged with the insulating covering member 2922. The wire 2921 constructed as described above is electrically connected to the supply line 22 shown in Fig. 1. The insulating cover member 2922 prevents a person who is working in the container yard Y from coming into contact with the wire 2921 and is electrically shocked. The insulating covering member 2922 is made of a material having electrical insulation. For example, a hollow casing made of resin or ceramics. As shown in Figure 9, The insulating covering member 2922 is in a cross section orthogonal to the longitudinal direction thereof. A concave portion 2922a is formed in an upper portion thereof. In addition, An opening portion 2922b is formed in a lower portion of the insulating cover 2922. The insulating cover member 2922 constructed as shown above is embedded in the wire 2921 inside thereof. The convex portion 2921b of the wire 2921 is engaged with the concave portion 2922a of the insulating covering member 2922 to be buckled " With this, Through the opening portion 292 2b of the insulating cover 2922, The wire 2921 is exposed to the outside. In addition, By the engagement of the convex portion 2921b and the concave portion 2922a, The wire 2921 is not held by the opening portion 2922b and is held inside the insulating covering member 2922" Next, The operation and effect of the RTG 10 according to the first embodiment of the present invention will be described. First of all, Using Figures 10 through 12, Indicate the positioning in the width direction of the travel path R of the RTG 10. As mentioned earlier, If driving along the travel path R is achieved by automatic driving, Due to the deviation of the distance or angle that occurs during autonomous driving, A slight snake will occur in the width direction of the driving path. therefore, Must not be affected by the snake, The electron collector 1352 belonging to one of the members constituting the power receiving device 13, The insulated overhead wire 292 which is one of the components constituting the power supply device 23-201206816 is actually in contact, And make these electrical connections. therefore, In the RTG 10 of the present invention, Before connecting the collector 1352 to the insulated overhead line 292, The positioning in the width direction of the traveling path R of the RTG 10 is performed. among them, In the following description, only the positioning operation of the upper guide roller pair 1 343 will be described. But for the lower guide roller pair 13 44, The same positioning operation as the upper guide roller pair 13 43 is also performed. If a snake occurs on the RTG 10 traveling along the travel path R, A slight shift in the width direction of the channel R occurs in the track through which the RTG 10 passes. In Figure 10(a), The width direction of the traveling path R is orthogonal to the direction in which the positioning plate 27 extends. In Figure 10 (a), it is indicated by a dotted line. If a snake occurs in the RTG10, The upper guide roller of the electronic trolley 134 is aligned with the track to be passed through. In addition, In the figure, a little chain line indicates that if there is no snake line, The original RTG10 should pass the track. As shown above, If a snake occurs in RTG10, Compared with the track (a little chain line) that should have passed, The track (dashed line) through which the upper guide roller pair 13 43 of the electronic cart 134 is to be passed is slightly offset in a direction orthogonal to the traveling direction of the RTG 10. at this time, As shown in Figure 10(b), The upper guide roller pair 13 43 which is located in the forward direction toward the traveling direction of the RTG 10 is in contact with the drum guide plate 26 in a region where the interval between the two roller guide plates 26 is gradually increased. As a result, The upper guide roller pair 13 43 begins to move along the roller guide plate 26. here, As mentioned earlier, The trolley body 13 42 belonging to the member constituting the electronic collecting cart 134 shown in Fig. 6 is allowed to have no ear in the width direction of the long hole 13 42 a. among them, The width direction of the long hole 1 342a may also be parallel to the direction of the RTG 10 -24-201206816, that is, the positioning plate 27. In addition, at this time, If the upper guide roller pair 1343 starts to move along the roller guide plate 26, The force received by the roller guide plate 26 by the upper guide roller pair 1 343, As shown in Figure 10(c), A slight tilt occurs in the 1 342 system of the trolley body. The RTG 10 is driven further forward by the state of Fig. 10 (c). In this way, As shown in Figure 11 (a), The upper guide roller pair 1 3 43 located in front of the traveling direction of the RTG 10 is in contact with the drum guide plate 26, The interval between the two roller guide sheets 26 is a constant area. then, A gap 1351 is formed between the upper guide roller pairs 1343 located in front of the traveling direction. Entering the gap 1351 by the positioning plate 27, The upper guide roller pair 13 43 is formed in a state in which the positioning plate 27 is held by the respective roller bodies 13 43 a . The RTG 10 is driven further forward by the state of Fig. 1 (a). In this way, As shown in Figure 11 (b), The upper guide roller pair 1 3 43 located at the rear of the traveling direction of the RTG 10 is in contact with the drum guide 26 in a region where the interval between the two roller guide plates 26 is gradually increased. As a result, The upper guide roller pair 1 3 43 also begins to move along the roller guide plate 26. then, As the upper guide roller pair 1 343 moves along the drum guide 26 toward the front of the traveling direction of the RTG 10, The inclination of the trolley body 1 342 with respect to the traveling direction is gradually reduced. The RTG 10 is driven further forward by the state of Fig. 11(b). In this way, The upper guide roller pair 1343 located behind the traveling direction of the RTG 10 is also in contact with the drum guide plate 26, The interval between the two roller guide plates 26 is a constant area. at this time, The trolley body 1342 may also be in a state parallel to the traveling direction of the RTG 10. then, The line located at RTG10 -25- 201206816 The upper guide roller pair 1 3 43 at the rear of the direction of travel is also shown in Figure 1 (c). A gap 1351 is formed between each of the drum main bodies 1 343a. The guide roller pair 1343 is formed by the positioning plate 27 to the gap 1351' to be in a state of holding the positioning plate 27 by the respective roller bodies 13 43 a . Thereby, a state in which the track through which the upper guide roller pair 1343 passes coincides with the track which should originally pass is formed. With the above, The positioning in the width direction of the traveling path R of the electronic cart 134 is completed. The RTG 10 is driven further forward by the state of Fig. 1 (c). In this way, As shown in Figure 12(a), The collector 1 3 52 located in front of the traveling direction of the RTG 10 is inserted into the inside from the one end side in the longitudinal direction of the insulated overhead wire 292. The collecting electrons 1352 are one of the components constituting the upper collecting electronic unit 1348. after that, As shown in Figure 12(b), The collector 1352 located behind the traveling direction of the RTG 10 is also inserted inside the insulated overhead wire 292. then, When the entirety of the upper collecting electronic unit 1 348 is inserted inside the insulated overhead wire 292, The RTG 10 system stops driving. In this state, Power is supplied to the RTG 10 by the power supply unit 20. among them, During the state from the state of Fig. 11 (c) to the state of Fig. 12 (a), Positioning of the upper and lower directions of the collection cart 134 is performed. Then use Figures 13 through 16, Indicate the positioning in the up and down direction of the RTG 10. As mentioned earlier, RTG 10 means a tire type crane 10, Drive on the tire column 12. therefore, The tire column 12 is deformed by the weight of the crane body 11 or the like. As a result, the RTG 10 system may slightly sink in the vertical direction (upper and lower directions). therefore, Must not be affected by the subsidence, The collectors 1352 constituting the power receiving unit 13 are reliably connected to the insulated overhead wires 2 92 constituting the power supply unit 23 26-2012068. therefore, In the RTG 10 of this embodiment, Positioning the width direction of the travel path R, Compared to the position where the up and down direction is positioned, It starts at the rear (upstream side) of the traveling direction of the RTG 10. among them, Contrary to this embodiment, Can also be positioned in the up and down direction, Compared to the position where the width direction of the traveling path R is positioned, It starts at the rear of the direction of travel of the RTG10. In addition, It is also possible to simultaneously position the positioning of the traveling path R in the width direction and the positioning in the vertical direction. If the RTG10 traveling along the travel path R collapses, A slight shift in the vertical direction occurs in the track through which the RTG 10 passes. The track through which the traveling roller 13 45 of the electronic cart 134 passes is indicated by a broken line in Fig. 13(a). In addition, In the figure, a little chain line indicates if there is no subsidence, The track that should have been passed. As shown above, Compared with the track (a little chain line) that should have passed, If the sinking occurs at RTG 1 0, The track (dashed line) through which the travel roller 1 345 of the electronic trolley 134 is to be passed is slightly offset downward. among them, In this state, the electronic collecting trolley 134 is guided by the upper guiding rail pair 131 which is in contact with the upper slider pair 13 46 from below. And is supported by the lower guide track pair 133' of the downward contact contact pair 1347 from below. at this time, The traveling roller 1 34 5 located in the traveling direction of the RTG 10 is in contact with the inclined portion 28b in the traveling table 28 for traveling. It starts to move along the inclined portion 28b. Here, the bogie body 1342 constituting the collecting cart 134 shown in Fig. 6 is allowed to be unstable to the longitudinal direction of the long hole 1342a. therefore, If the roller 1 3 45 starts to move along the carriage 28 along the travel roller -27-201206816, The line roller 1345 is subjected to the frame 28 by the driving fish. With this force, As shown in Figure 13 (b), The trolley body 1 342 is formed in a state in which the front side of the traveling direction is lifted and tilted. on the other hand, Upper guide bow|track pair 131 extending from the crane body 11 of the RTG 10, Lower guide bow | track pair 133, And the slide restricting member 132 is maintained in a horizontal state. The upper slider pair 1346 constitutes one of the members of the electronic collection trolley 134. therefore, As shown in Figure 13 (b), In a state where the trolley body 1 342 is inclined, The upper slider pair 1346 located behind the traveling direction of the RTG 10 maintains a state in which it is in contact with the upper guide rail pair 131. The upper slider pair 1346 located in front of the traveling direction is away from the upper guide rail pair 131. With this, The collecting cart 13 4 supports the front portion in the traveling direction of the RTG 10 by the traveling drum stand 28. on the other hand, The collecting electronic vehicle 134 is formed in a state in which the portion located rearward in the traveling direction of the RTG 10 is supported by the upper guiding track pair 131 and the lower guiding track pair 133. here, Fig. 16 is a view for explaining the operation of the carriage body 13 42 and the upper guide roller pair 13 43 when the positioning of the electronic collecting cart 134 is performed in the vertical direction. As shown in Figure 13 (b), When the portion in front of the traveling direction of the truck body 1 3 42 is lifted and tilted, The roller support piece 1341 provided on the carriage body 13 42 is raised in a position indicated by a solid line in a position indicated by a two-dot chain line in Fig. 16. here, As mentioned earlier, The rotation support shaft 1343b of the upper guide roller pair 1343 is supported by being slidable in the axial direction by the slide bearing 1341b and the slide bearing 1341e. therefore, Even if the roller support piece 1341 rises, The sliding bearing 1341b and the sliding bearing 1341e are also moved along the rotating support shaft 1 343b. The upper guide roller pair 1 343 does not move -28-201206816 in the up and down direction. When positioning the upper and lower directions of the electronic trolley 134, It is formed in a state in which the upper guide roller pair 1 343 is in contact with the drum guide 26 or the positioning plate 27. Even in this state, The upper guide roller pair 1 343 does not move up and down. Therefore, when the roller support piece 1341 rises, There is no possibility that the upper guide roller pair 1343 is slid and worn by the roller guide plate 26 or the positioning plate 27. The RTG 10 is further driven by the state shown in Fig. 13(b). As a result, As shown in Figure 14 (a), The running roller 13 45 located in the forward direction of the RTG 10 is placed on the parallel portion 28a by the inclined portion 28b of the traveling roller mount 28. on the other hand, The running roller 1 345 located at the rear in the traveling direction of the RTG 10 is also in contact with the inclined portion 28b. It starts to move along the inclined portion 28b. Accompanying this, The portion of the trolley body 13 42 that is connected to the rear side in the traveling direction of the RTG 10 is also slowly lifted. With this, The upper end and the lower end of the trolley body 1 3 42 are formed to be parallel (horizontal) with the road surface of the traveling path R. Then, The upper slider pair 1 346 constituting the integrated electronic trolley 134 is formed in the following state. that is, As shown in Figure 14 (b), Both the front slider pair 134 6 located in the traveling direction of the RTG 10 and the rear upper slider pair 13 46 are separated from the upper guiding rail pair 131. With this, The integrated electronic carriage 13 4 is formed to support the state of both the upper slider pair 1 346 located in the forward direction of the RTG 10 and the upper slider pair 1 346 located in the rear direction of the RTG 10 by the traveling drum stand 28 then, The row roller 1 345 located rearward in the traveling direction of the RTG 10 is also placed on the parallel portion 28a by the inclined portion 28b of the gantry roller gantry 28. As a result, The track through which the traveling roller 1 345 passes is formed in a state consistent with the original -29-201206816. The positioning of the upper and lower center of the electronic trolley 134 is completed. after that, If RTG 1 0 is driving more, As shown in Figure 15 (a), The collecting electrons 1 3 52 constituting the upper collecting electron unit 1 348 are inserted inside by the one end of the insulating overhead wire 2 92 in the longitudinal direction. At this point, The RTG 10 series stops driving. The supply of electric power is started by the power supply unit 20. among them, Each shape or combination of the constituent members shown in the above embodiment, Or the order of actions, etc. is an example. Without departing from the gist of the invention, Various changes can be made according to design requirements and the like. E.g, In the above embodiment, a crane system including a tire type crane apparatus will be described. but, The invention is not limited to a crane system, It can be applied, for example, to a power supply system that supplies power to a self-propelled device including a tire type crane device. that is, It can also be equipped with the above insulated overhead wire 292, Set electronic trolley 134, Set electronic 1352 and support institutions (pillar 1353a, Arm member 1353b, Pressing roller 1353c, The spring-loading spring 1 3 53 d ) is supplied with a self-propelled device other than the wheeled crane. With the power supply device, In self-propelled devices other than tire-type cranes, Also when powering the device, Offset the position of the device. The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments.
