1270522 (1) 九、發明說明 【發明所屬之技術領域】 本發明係關於檢測到昇降機之車廂或平衡配重之運行 速度超過時,使昇降機之超速開關及鋼索夾件作動之調速 機構。 【先前技術】 在規定昇降機之安全裝置的日本建築基準法施行令的 129條之10第2號、及平成12年(西元2000年)日本 建設省告示第1 4 3 2號第2條第2號之中規定,必須設置 有,當下降的車廂速度超過規定値之時,使車廂的下降自 動地制止之裝置。 第11圖係顯示設置有緊急停止裝置之一般的昇降機 之槪略機構,昇降機之車廂1被主鋼索2所懸吊著,並由 未圖示的捲揚機而在昇降路內昇降,同時由設置在該昇降 路內的導軌3而引導該昇降。車廂1上裝設有緊急停止裝 置4,其係被構成在當主鋼索21斷裂、或是捲揚機之旋 轉速度有異常,因而使昇降機之車廂1速度變成定格速度 以上之時,可將導軌3夾住,而使車廂1以機械的方式被 停止。即’昇降機之過速度被設置於機械室中的調速機構 5所檢測之時,可使組裝於該調速機構5中的鋼索夾件6 作動,因而使捲繞於調速機構5中的調速機鋼索7被夾住 。如此地,當調速機鋼索7被夾住之時,藉由裝設於車廂 1上的安全連桿8,可使緊急停止裝置4動作。 -4- (2) 1270522 第1 2圖顯示使用於高速昇降機中之一般的調速機構 。一般的調速機構5具備有:捲繞有調速機鋼索7的滑輪 車8、與滑輪車8之旋轉連動而產生離心力的旋轉配重9 、隨著連結到旋轉配重9之離心力的變化而進行運動之上 部調速機連桿1 0 a、控制上部調速機連桿1 〇 a之運動而控 制調速機構5之運動速度之速度調整彈簧1 2、及下部調 速機連桿1 〇 b,在昇降機達到規定以上的速度之時,可使 過速開關11動作。並且,調速機構5具備有,在速度更 上昇之時動作而將調速機鋼索7夾住的鋼索夾件6、與該 鋼索夾件6成對向,而將調速機鋼索7夾住的固定側鋼索 夾件1 3、及將預定的夾住力賦予該鋼索夾件6的夾住彈 簧14 〇 並且,如第13圖及第14圖所示,設置有:組裝有夾 住彈簧1 4,而支持鋼索夾件6之運動的腕部1 5、連結該 腕部1 5及鋼索夾件6的連接部1 6、及成爲該腕部1 5的 旋轉運動之支點的轉軸1 7。在此處,第1 4圖係第1 3圖 從上面看去之平面圖。 亦即,由下部調速機連桿1 0 b而使鋼索夾件動作之時 ,腕部1 5與鋼索夾件6 —起以轉軸1 7爲中心而進行旋轉 下降運動,使鋼索夾件6接觸調速機鋼索7。其次,由於 和該調速機鋼索7的接觸部之摩擦力,而更使鋼索夾件6 向下方拉動(拉入),因而與固定側鋼索夾件13 —起開 始調速機鋼索7之把持動作。 如此,將鋼索夾件6向下方拉動之時,腕部1 5 —面 -5- (3) 1270522 將夾住彈簧1 4押壓,一面進行旋轉下降運動,此時之夾 住彈簧1 4之押壓力藉由連接部1 6而做爲把持力被傳遞到 鋼索夾件6上。由於該鋼索夾件6僅以預定之量而向下方 被拉動之時,鋼索夾件6衝突到基板1 8上而拘束旋轉下 降運動,此時之夾住彈簧1 4以預定之把持力而將調速機 鋼索7把持。由此一連串之動作,鋼索夾件6以預定之力 而把持調速機鋼索7,藉由安全連桿8而使緊急停止裝置 4動作。 【發明內容】 (發明欲解決的課題) 如第1 2圖所示,先前技術之調速機,係利用由配重 9之離心力而運動的上部調速機連桿1 〇a、及下部調速機 連桿l〇b而直接操作過速開關11。 第1 5圖係將先前技術之操作力-速度的關係以曲線顯 示者。如曲線所示,在過速開關之作動的前後,由於動作 抵抗力之變化,而使操作力之變化的連續性消失。 並且,在過速開關1 1正要作動之前,配重9之離心 力、彈簧12之力、動作抵抗彼此平衡。然而,過速開關 1 1作動之時,過速開關1 1之動作抵抗急速地被除去,而 失去平衡,因而以配重9之平衡位置做中心而產生彈性振 動。當其峰値超過靜態平衡條件之鋼索夾住動作位置之時 ,會有以比規定速度更低的速度而誤動作之可能性。 加上,該動作抵抗力依照每個過速開關1 1之製品而 -6- (4) 1270522 有誤差,作動抵抗力會有大到開關之操作力之差以上之情 形,因此開關之選別有其需要。 當操作力之變化的連續性消失之時,從過速開關11 作動到鋼索夾件6作動沒有充分的速度差之時,會使調整 變成困難。 並且,在日本平成12年建設省告示第1432號第2條 第2號之中要求,在過速開關1 1中,作動後其性質上在 進行人爲的復位作業之前,亦需進行保持動作(電路切斷 )。截至目前,有將保持動作之功能附加於開關之需要性 ,因此由係附加裝置達成省空間化或成本降低之限制。 本發明係考慮此點而開發者,其目的在提供一種並非 將外徑尺寸做大,而係調整容易且可靠度高的昇降機之調 速機構。 (解決課題之手段) 本發明係使昇降機之過速開關及鋼索夾件作動之昇降 機之調速機構,其特徵爲:具備有:隨著捲繞有昇降機之 調速機鋼索的滑輪車之旋轉而作動之調速機連桿、與該調 速機連桿連動而轉動之凸輪、與該凸輪卡合,同時自由轉 動地設置之臂,利用該臂之轉動而使該過速開關作動。 本發明係,臂具有與凸輪卡合之輥軸,上述輥軸係位 於上述凸輪之轉動中心的垂直線上爲其特徵之昇降機之調 速機構。 本發明係以:其又具備有:與凸輪連動而轉動之追加 -7- (5) 1270522 凸輪、及將和該追加凸輪連動而轉動之鋼索夾件驅動之追 加臂,利用該追加臂之轉動而使該過速開關被自由地作動 ,做爲其特徵之昇降機之調速機構。 本發明係以:在臂的附近設置有:臂在將過速開關作 動之時所抵接的衝擊吸收體,做爲其特徵之昇降機之調速 機構。 本發明係以:在臂的轉軸上設置有臂在將過速開關作 動之時防止過速開關復位的臂棘輪機構、在臂上設置有臂 在將過速開關作動之時防止過速開關復位的彈簧銷機構' 在凸輪之轉軸上設置有臂在將過速開關作動之時防止過速 開關復位的凸輪棘輪機構、在凸輪上設置有臂在將過速開 關作動之時防止過速開關復位的凸輪彈簧銷機構,做爲其 特徵之昇降機之調速機構。 本發明係以:在臂上安裝有配重,而使臂之轉動力增 加,做爲其特徵之昇降機之調速機構。 本發明係以:在臂上安裝有彈簧,而使臂之轉動力增 加,做爲其特徵之昇降機之調速機構。 (發明之効果) 依照本發明,爲了將在鋼索夾件作動之前階段作動之 過速開關予以作動,而使用臂及凸輪,使過速開關可間接 地進行操作。因此可使調速機構之操作力的過速開關所引 起的操作力之不連續性變小。因而’即使在截至目前調整 困難之超高速昇降機之中,可具有高可靠度調速機構。加 -8 - 1270522 (6) 上利用臂而將過速開關保持動作之時,可使用標準絞鏈輥 軸桿型之開關,因而可達成成本降低及省空間化。 依照本發明,使凸輪之轉動中心與弧的中心一致,使 和其垂直線上具有輥軸的負荷點之時,凸輪在反復運動時 之動作抵抗之平均變成最小,因而可正確地保持操作力之 連續性。 依照本發明,因爲具有與鋼索夾件之動作連動且於鋼 索夾件之作動時可再度將過速開關作動之機構,因此即使 過速開關無論任何原因不作動之時,其亦可再度嘗試過速 開關之作動,因此可提高可靠度。 依照本發明,爲了防止過速開關之誤復位,在臂承座 上設置有衝擊吸收體,因而可提高可靠度。 依照本發明,在臂上設置有臂棘輪機構以防止過速開 關的誤復位,因而可提高可靠度。 依照本發明,在臂上設置有臂彈簧銷機構以防止過速 開關的誤復位,因而可提高可靠度。 依照本發明,在臂上設置有凸輪棘輪機構以防止過速 開關的誤復位,因而可提高可靠度。 依照本發明,在臂上設置有凸輪彈簧銷機構以防止過 速開關的誤復位,因而可提高可靠度。 依照本發明,在臂上安裝有配重以增加轉動力,因而 使臂達成小型化及過速開關之操作力的提高,因此亦可容 易地適用於操作力大的開關。 依照本發明,爲了增加臂之轉動力而使用彈簧之故, -9- 1270522 (7) 因此可更達成臂之小型化或操作力之提高。 【實施方式】 以下將參照附圖而說明本發明之實施形態。 第1圖至第5圖,係顯示本發明昇降機之調速機構之 一個實施形態之圖。 如第1圖至第5圖所示,調速機構5和先前技術者同 樣地,具備有:捲繞有調速機鋼索7的滑輪車8、與滑輪 車8之旋轉連動而產生離心力的旋轉配重9、隨著連結到 旋轉配重9之離心力的變化而進行運動之上部調速機連桿 1 〇a、控制上部調速機連桿1 0a之運動而控制調速機構5 之運動速度之速度調整彈簧12、及隨著速度調整彈簧12 之作動而朝上下方向移動之下部調速機連桿1 〇b (參照 第1圖及第12圖)。然後,如後述者,由於下部調速機 連桿1 0 b之動作,而使昇降機之過速開關1 1及鋼索夾件 6被作動。 並且,調速機構5具備有:設置於基板1 8上,與下 部調速機連桿1 〇 b連動,而在設置於機座3 3上之轉軸2 2 的周圍轉動的凸輪19、具有卡合於凸輪19上之凸輪輥軸 2〇而在轉軸17周圍轉動之臂21,在臂21上固定有配重 30 ° 並且,在基板1 8上設置有在轉軸2 5 a周圍轉動的連 桿24及追加凸輪25’連桿24係卡合於在轉軸22的周圍 轉動的連桿2 4 a上。 -10- 1270522 (8) 並且,在轉軸17上設置有自由轉動的腕15,該腕15 上捲繞固定有夾住彈簧1 4,同時鋼索夾件6介由轉軸1 6 而安裝於腕1 5的前端上。 並且,在基板1 8上設置有對向於鋼索夾件6的固定 側鋼索夾件1 3,在該固定側鋼索夾件1 3與鋼索夾件6之 間夾持著調速機鋼索7。 並且在基板1 8上設置有,如後述般,臂2 1將過速開 關1 1作動之時抵接於臂2 1上的衝擊吸收體3 7。並且, 在轉軸1 7上自由轉動地設置有與鋼索夾件6之腕1 5連動 而動作的桿23。 如第1圖至第5圖所示,和先前技術不同之處,並非 由於下部連桿1 〇b之轉動而使過速開關1 1被操作,而係 下部連桿1 Ob轉動使臂2 1從凸輪1 9落下而產生之轉動力 使過速開關1 1被操作之點。 而,第3 ( a ) ( b ) ( c )圖係過速開關1 1之側面圖 ,分別爲:第3 ( a )圖係顯示臂2 1之落下前的狀態,並 且第3 ( b )圖係顯示由於臂2 1之落下使過速開關1 1作 動而保持動作中之狀態,第3 ( c )圖係顯示由桿23使過 速開關1 1再作動而保持動作中之狀態。 其次,將說明由如此的構成所形成之本實施形態的作 用。 下部連桿1 〇b隨著滑輪車8 (參照第12圖)之離心 力之增加而被拉向上方之時,轉軸22向右旋轉,使固定 於轉軸2 2上的凸輪1 9亦連動而向右旋轉。因此,凸輪輥 -11 - 1270522 (9) 軸2 0從凸輪1 9脫離使臂2 1落下(第4圖)。 臂21落下之時,利用臂21之面落下部21a使過速開 關1 1圓滑地作動,該過速開關1 1係穩定地持續保持在臂 2 1之側面作動的狀態(第3 ( a ) ( b )圖)。 並且,滑輪車8之離心力增加時,固定於轉軸22上 之連桿2 4 a將固定於轉軸2 5 a上之連桿2 5向左轉動。此 時,凸輪輥軸2 6從連桿2 5脫離,使鋼索夾件6之腕1 5 下降而將鋼索夾件6作動。此時,鋼索夾件6之腕1 5介 由轉軸1 7而連接到桿23上,因此鋼索夾件6作動之時, 桿2 3亦與腕1 5同樣地轉動,因而使過速開關1 1再度被 作動(第3 ( c )圖)。因此即使臂21之動作使過速開關 未被切斷之時,桿23亦可將過速開關1 1作動。 如此,鋼索夾件6作動之時將過速開關1 1切斷,係 歐洲規格(EN 8 1 -1 )中所規定。 因而,利用下部調速連桿1 〇b使過速開關1 1可介由 凸輪1 9、臂21、追加凸輪2 5及桿2 3而間接地操作,因 此由下部調速連桿1 〇b而將過速開關1 1直接操作變成不 需要,故可排除過速開關1 1之動作抵抗。因此與先前技 術比較時,可排除過速開關1 1之動作力的變動等之誤差 要因,可使調速機構5之操作力的不連續性變小(參照第 1 5圖及第1 6圖)。上述之技術在目前必須將離心力之變 化做成小且調整困難的調速機構5尤其有効。 但是在第1圖中,設置於臂21上的凸輪輥軸20之負 荷點,係在凸輪1 9之轉軸22的中心之垂直線上,而且凸 -12- 1270522 (10) 輪1 9之弧1 9 a的中心與轉軸2 2的中心爲一致。此時 輪輥軸20與臂21之自重,無法將轉矩介由凸輪19 遞到轉軸2 2上,因此不會成爲轉軸2 2的旋轉抵抗。 ,過速開關1 1之操作力和凸輪1 9之旋轉量及臂2 1 置無關而連續地變化。並且,過速開關1 1係如上述 地被操作之故,因此過速開關1 1之操作力完成對調 構5之動作力毫無影響。 因而,調速機構5之動作力的連續性可被保持之 因此可進一步提高其可靠度,並且可使調速性能提高 而,過速開關1 1被作動一次之情況時,由專門 者確認其安全之後,以手動方式實施復位作業,雖然 日本平成12年日本國建設省告示第1 423號第2條第 之中係爲必須的義務,但是亦可考慮利用臂2 1之跳 實施自動復位。 依照本發明,利用衝擊吸收體3 7可確實地防止, 之跳回。此時,考慮價廉之構造的單純觀點,或使f 之跳回,而以鋼索夾件6之作動時的衝擊自動復位之 性,最好使用低彈性橡膠做爲衝擊吸收體3 7較佳。 其次’將以第6圖及第7圖說明本發明之變形例 如第6(a) (b)圖所示,亦可在由臂21將過 關1 1作動之後,以防止過速開關1 1之誤復位爲目的 轉軸17之周圍設置棘輪(臂棘輪)27。該棘輪27係 定於轉軸1 7側之部分27b、及固定於臂2 1側的部分 所形成,邰分2 7 a、2 7 b係由彈簧2 8而互相押壓地保 ,凸 而傳 從而 之位 間接 速機 故, 〇 技術 此在 二號 回而 f 21 t 21 可能 〇 速開 而在 由固 27a 持。 -13- 1270522 (11) 在此處’弟6(a)圖係顯不棘輪的平面圖,第6(b)圖 係其側面圖。 使過速開關1 1復位之時’係採用將臂2 1朝正前方拉 動亦不會解除棘輪27之齒輪而無法復位的構造,以防止 誤復位。 並且,與第6(a) (b)圖所示之棘輪27同樣地目 的’如弟弟7(a) (b)圖所不’亦可在轉軸17之周圍 設置彈簧銷2 9。在此處,第7 ( a )圖係顯示與彈簧銷孔 卡合前之圖,第7 ( b )圖係顯示與彈簧銷孔之卡合作用 之圖。 在本變形例中,臂2 1轉動到而使過速開關1 1作動之 位置爲止之時,安裝於臂2 1側的彈簧銷2 9嵌合到設置於 轉軸1 7側的孔3 8中。此時,只要不將彈簧銷29與孔3 8 解除的g舌’其後臂2 1即無法轉動。在此處,係由彈簧銷 2 9與孔3 8構成彈簧銷機構(臂彈簧銷機構)。彈簧銷2 9 的設置成本係一般係考慮在衝擊吸收體37與棘輪27之中 間程度。 如以上所述,將旋轉抑制機構2 7、2 9、3 8設置於臂 2 1上之時,可防止過速開關丨1的誤復位。 其次5將以第8圖及第9圖說明本發明之另外的變形 例。 如第8 ( a ) ( b )圖所示,亦可在轉軸2 2的周圍設 置棘輪(凸輪棘輪)3 2。棘輪3 2係由固定在轉軸側的部 分3 2 b、及固定在機座3 3側的部分3 2 a所形成,部分3 2 a (12) 1270522 、3 2b係由彈簧34而互相押壓地保持。在此處,第8 ( a )圖係顯示棘輪的平面圖,第8 ( b )圖係顯示棘輪的側 面圖。 在本變形例中,即使臂2 1之跳回之時,凸輪1 9亦不 承住臂2 1之故,因此不會有過速開關1 1復位的問題。過 速開關Π之復位,係採用將臂2 1朝正前方拉動亦不會解 除棘輪2 7之齒輪而無法復位的構造。 棘輪3 2之動作力,可由彈簧3 4之強度及棘輪3 2之 高度、角度而做成小,故只要有防止凸輪1 9之逆旋轉的 程度之抵抗的話即可。因此,設置棘輪3 2對過速開關1 1 之操作力的連續性之影響很少。 並且,如第9(a) ( b )圖所示,爲了同樣地防止過 速開關1 1之誤復位,亦可設置由凸輪3 5及彈簧銷3 6所 形成的彈簧銷機構(臂彈簧銷機構)。 在第9 ( a ) ( b )圖中,連結到轉軸2 2之凸輪3 5係 與凸輪1 9 —起向右方轉動。凸輪1 9轉動,使凸輪輥軸 20從凸輪19脫離而使臂21落下之時,設置於機座33側 之彈簧銷3 6嵌合到凸輪3 5上。彈簧銷3 6嵌合到凸輪3 5 上之時,雖然凸輪3 5可與凸輪1 9 一起向右方持續地旋轉 ,但是無法與凸輪1 9 一起向左方旋轉而朝臂2 1落下之點 回歸。因此,可防止過速開關1 1之誤復位。 並且,將球等裝入彈簧銷3 6的前端之時,可使滑動 抵抗做爲旋轉抵抗,因而可使操作力之不連續點做成極小 -15- (13) 1270522 復次,將以第1 〇圖說明本發明之另外的變形例。在 第1圖至第5圖所示之實施形態中雖然顯示有,在臂2 J 上設置配重3 0,使臂2 1之長度做成短而達成價廉之省空 間化之例子,但是並不拘限於此,如第1 0圖所示,亦可 使用彈簧3 1取代配重3 0,以使臂2 1之轉動力增加。在 第1 0圖中,可因應於設置空間而使用押壓彈簧3 1。使用 彈簧31之時,可以比使用配重3 0之情況使臂2 1之動作 力更增大。 【圖式簡單說明】 第1圖係顯示本發明昇降機之調速機構之一實施形態 的圖。 第2圖係第1圖顯示之昇降機之調速機構的平面圖。 第3圖係顯示本發明昇降機之調速機構的作用之圖。 第4圖係顯示本發明昇降機之調速機構中過速開關的 動作狀態之圖。 第5圖係顯示鋼索夾件作動狀態之圖。 第6圖係顯示本發明昇降機之調速機構的變形例之圖 〇 第7圖係顯示本發明昇降機之調速機構的變形例之圖 〇 第8圖係顯示本發明昇降機之調速機構的變形例之圖 〇 第9圖係顯示本發明昇降機之調速機構的變形例之圖 -16- 1270522 (14) 第1 0圖係顯示本發明昇降機之調速機構的變形例之 圖。 第11圖係設置有緊急停止裝置及調速機構之一般的 昇降機之槪略構成圖。 第1 2圖係顯示先前技術之調速機構之一例的圖。 第1 3圖係顯示先前技術之鋼索夾件的側面圖。 第1 4圖係顯示第i 3圖所顯示之鋼索夾件的平面圖。 第1 5圖係顯示先前技術之調速機構之過速開關之操 作力之圖。 第1 6圖係顯示依照本發明之先前技術的調速機構之 過速開關之操作力之圖。 [主要元件符號說明】 5…調速機構 6…鋼索夾件 7…調速機鋼索 l〇a…上部調速機連桿 10b…下部調速機連桿 11…過速開關 1 2…速度調整彈簧 13…固定側鋼索夾件 14···夾住彈簧 1 5…腕部 •17- (15) 1270522 1 6…連接部 1 7…轉軸 18…基板 19,35…凸輪 20,26.··凸輪輥軸 21…臂BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speed governing mechanism for operating an overspeed switch and a cable clamp of an elevator when the running speed of the elevator car or the balance weight is exceeded. [Prior Art] 129 of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations of the stipulations In the number, it is necessary to provide a device for automatically stopping the lowering of the car when the descending car speed exceeds a predetermined speed. Figure 11 is a schematic diagram showing a general elevator equipped with an emergency stop device. The car 1 of the elevator is suspended by the main cable 2, and is lifted and lowered in the hoistway by a hoist not shown, and is disposed at the same time. The rails 3 in the hoistway guide the lifting. The vehicle compartment 1 is provided with an emergency stop device 4, which is configured to clamp the guide rail 3 when the main cable 21 is broken or the rotational speed of the hoist is abnormal, so that the speed of the elevator car 1 becomes higher than the rated speed. Live, and the car 1 is stopped mechanically. That is, when the speed of the elevator is detected by the speed governing mechanism 5 provided in the machine room, the cable clamp member 6 assembled in the speed governing mechanism 5 can be actuated, thereby being wound in the speed governing mechanism 5. The governor cable 7 is clamped. Thus, when the governor cable 7 is clamped, the emergency stop device 4 can be operated by the safety link 8 attached to the passenger compartment 1. -4- (2) 1270522 Figure 1 2 shows the general governing mechanism used in high-speed lifts. The general speed governing mechanism 5 includes a pulley cart 8 around which the governor cable 7 is wound, a rotary counterweight 9 that generates centrifugal force in conjunction with the rotation of the pulley cart 8, and a change in centrifugal force coupled to the rotary counterweight 9. And the speed adjustment spring 1 for controlling the speed of the speed governing mechanism 5 and the lower speed governing machine connecting rod 1 for controlling the movement speed of the upper speed governing machine connecting rod 1 〇a 〇b, when the elevator reaches a speed higher than or equal to a predetermined speed, the overspeed switch 11 can be operated. Further, the speed governing mechanism 5 is provided with a cable clamp member 6 that operates when the speed is increased to sandwich the speed governor cable 7, and is opposed to the cable clamp member 6, and clamps the speed governor cable 7 The fixed side cable clamp member 13 and the predetermined clamping force are applied to the cable clamp member 6 to clamp the spring 14 〇 and, as shown in Figures 13 and 14, are provided with: a clamped spring 1 is assembled 4, a wrist portion 15 supporting the movement of the cable clamp member 6, a connecting portion 16 connecting the wrist portion 15 and the cable clamp member 6, and a rotating shaft 17 serving as a fulcrum of the rotational motion of the wrist portion 15. Here, Figure 14 is a plan view from above. That is, when the cable clamp member is operated by the lower speed governor link 10b, the wrist portion 15 and the cable clamp member 6 are rotated downwardly about the rotation shaft 17 to make the cable clamp member 6 Contact the speed control cable 7 . Secondly, due to the frictional force with the contact portion of the governor cable 7, the cable clamp member 6 is pulled downward (pull-in), thereby starting the control of the governor cable 7 together with the fixed-side cable clamp member 13. action. In this way, when the cable clamp member 6 is pulled downward, the wrist portion 5 5 -5-(3) 1270522 is pressed against the spring 14 to perform a rotation downward movement, and at this time, the spring 14 is clamped. The pressing force is transmitted to the cable clamp member 6 as a holding force by the connecting portion 16. Since the cable clamp member 6 is pulled downward only by a predetermined amount, the cable clamp member 6 collides with the substrate 18 to restrain the rotation downward movement, and at this time, the spring 14 is clamped with a predetermined holding force. The speed control cable 7 is held. With this series of actions, the cable clamp member 6 holds the governor cable 7 with a predetermined force, and the emergency stop device 4 is actuated by the safety link 8. SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) As shown in FIG. 2, the governor of the prior art utilizes an upper speed governor link 1 〇a that is moved by the centrifugal force of the counterweight 9, and a lower adjustment. The overspeed switch 11 is directly operated by the speed machine link l〇b. Figure 15 shows the relationship between the prior art operating force-velocity as a curve. As shown in the graph, the continuity of the change in the operating force disappears due to the change in the resistance of the action before and after the operation of the overspeed switch. Further, before the over-speed switch 1 1 is to be actuated, the centrifugal force of the counterweight 9, the force of the spring 12, and the action are balanced against each other. However, when the over-speed switch 1 1 is actuated, the action of the over-speed switch 1 1 is quickly removed, and the balance is lost, so that the elastic vibration is generated centering on the balance position of the weight 9 . When the cable whose peak value exceeds the static equilibrium condition is caught by the action position, there is a possibility that the motor will malfunction at a lower speed than the predetermined speed. In addition, the action resistance is in accordance with the product of each over-speed switch 1 1 - 6 - (4) 1270522 has an error, the actuation resistance may be greater than the difference between the operating forces of the switch, so the selection of the switch has It needs. When the continuity of the change in the operating force disappears, the adjustment becomes difficult when the overspeed switch 11 is actuated until the cable clamp 6 is actuated without a sufficient speed difference. In addition, in the No. 2, 2nd, No. 2, No. 1432 of the construction of the Ministry of Construction in Japan, it is required to maintain the nature of the over-speed switch 1 1 after the artificial reset operation. (Circuit cut). Up to now, there has been a need to attach a function to keep the action to the switch, so that the system is limited in space saving or cost reduction. The present invention has been made in view of the above, and an object thereof is to provide an adjustment mechanism for an elevator which is not easy to adjust the outer diameter and which is easy to adjust and has high reliability. (Means for Solving the Problem) The present invention is a speed governing mechanism for an elevator that operates an overspeed switch and a cable clamp of an elevator, and is characterized in that: the rotation of the pulley car with the speed governor cable wound with the elevator is provided And the actuating speed controller linkage, the cam rotating in conjunction with the speed controller linkage, and the cam engaged with the cam, and being freely rotatably provided, the excessive speed switch is actuated by the rotation of the arm. According to the present invention, the arm has a roller shaft that engages with a cam, and the roller shaft is a speed adjusting mechanism of the elevator characterized by a vertical line on the center of rotation of the cam. According to the present invention, there is provided an additional 7-(5) 1270522 cam that rotates in conjunction with a cam, and an additional arm that drives a cable clamp that rotates in conjunction with the additional cam, and the additional arm is rotated by the additional arm The overspeed switch is freely actuated as a speed governing mechanism for the elevator of its characteristics. The present invention is characterized in that: in the vicinity of the arm, an impact absorber that abuts against the arm when the overspeed switch is actuated is provided as a speed governing mechanism of the elevator characterized by the feature. The invention is characterized in that: an arm ratchet mechanism for preventing the overspeed switch from being reset when the overspeed switch is actuated is provided on the rotating shaft of the arm, and an arm is provided on the arm to prevent the overspeed switch from being reset when the overspeed switch is actuated The spring pin mechanism' is provided with a cam ratchet mechanism for preventing the overspeed switch from being reset when the overspeed switch is actuated on the rotating shaft of the cam, and an arm is provided on the cam to prevent the overspeed switch from being reset when the overspeed switch is actuated The cam spring pin mechanism is used as a speed governing mechanism for the elevator of its characteristics. The present invention is characterized in that a counterweight is attached to the arm, and the rotational force of the arm is increased, and the speed governing mechanism of the elevator is characterized. The present invention is characterized in that a spring is attached to the arm, and the rotational force of the arm is increased, and the speed governing mechanism of the elevator is characterized. (Effect of the Invention) According to the present invention, the overspeed switch can be operated indirectly in order to operate the overspeed switch that is actuated before the wire clamp is actuated, and the arm and the cam are used. Therefore, the discontinuity of the operating force caused by the overspeed switch of the operating force of the governing mechanism can be made small. Therefore, even in the ultra-high-speed elevators that have been difficult to adjust so far, it is possible to have a high-reliability speed governing mechanism. -8 - 1270522 (6) When the overspeed switch is held by the arm, the standard hinge roller shaft type switch can be used, resulting in cost reduction and space saving. According to the present invention, when the center of rotation of the cam coincides with the center of the arc so as to have a load point of the roller shaft on the vertical line thereof, the average of the action resistance of the cam during repeated movement becomes minimum, so that the operation force can be correctly maintained. Continuity. According to the present invention, since the mechanism can be operated again in conjunction with the action of the cable clamp member and the overspeed switch can be actuated when the cable clamp member is actuated, even if the overspeed switch is not actuated for any reason, it can be tried again. The speed switch operates to improve reliability. According to the present invention, in order to prevent erroneous reset of the overspeed switch, the impact absorbing body is provided on the arm socket, so that reliability can be improved. According to the present invention, an arm ratchet mechanism is provided on the arm to prevent erroneous reset of the overspeed switch, thereby improving reliability. According to the present invention, an arm spring pin mechanism is provided on the arm to prevent erroneous reset of the overspeed switch, thereby improving reliability. According to the present invention, a cam ratchet mechanism is provided on the arm to prevent erroneous reset of the overspeed switch, thereby improving reliability. According to the present invention, a cam spring pin mechanism is provided on the arm to prevent erroneous reset of the overspeed switch, thereby improving reliability. According to the present invention, the weight is attached to the arm to increase the rotational force, so that the arm is miniaturized and the operating force of the over-speed switch is improved, so that it can be easily applied to a switch having a large operating force. According to the present invention, in order to increase the rotational force of the arm, the spring is used, -9-1270522 (7), so that the miniaturization of the arm or the improvement of the operating force can be achieved. [Embodiment] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figs. 1 to 5 are views showing an embodiment of a governing mechanism of the elevator of the present invention. As shown in FIGS. 1 to 5, the speed governing mechanism 5 includes, similarly to the prior art, a pulley cart 8 around which the governor cable 7 is wound, and a rotation that generates centrifugal force in conjunction with the rotation of the pulley cart 8. The counterweight 9 controls the movement speed of the speed governing mechanism 5 by moving the upper speed governing machine connecting rod 1 〇a and controlling the movement of the upper speed regulating mechanism connecting rod 10a as the centrifugal force connected to the rotating counterweight 9 changes. The speed adjusting spring 12 and the lower speed adjusting lever 12 are moved in the vertical direction as the speed adjusting spring 12 is actuated (see FIGS. 1 and 12). Then, as will be described later, the overspeed switch 1 1 and the cable clamp 6 of the elevator are actuated by the operation of the lower speed governor link 10 b. Further, the speed governing mechanism 5 is provided with a cam 19 that is provided on the substrate 18 and that rotates in conjunction with the lower speed governor link 1 〇b, and rotates around the rotating shaft 2 2 provided on the base 33, and has a card. An arm 21 that rotates around the rotating shaft 17 on the cam roller shaft 2 of the cam 19, a weight of 30° is fixed to the arm 21, and a connecting rod that rotates around the rotating shaft 25a is provided on the substrate 18. 24 and the additional cam 25' link 24 are engaged with the link 24a that rotates around the rotating shaft 22. -10- 1270522 (8) Further, a freely rotatable wrist 15 is provided on the rotating shaft 17, and the wrist 15 is wound and fixed with a clamp spring 14 and the cable clamp 6 is attached to the wrist 1 via the rotating shaft 16 On the front end of 5. Further, a fixed side cable clamp member 13 opposed to the cable clamp member 6 is disposed on the substrate 18, and a governor cable 7 is interposed between the fixed side cable clamp member 13 and the cable clamp member 6. Further, the substrate 18 is provided, and as will be described later, the arm 2 1 abuts against the impact absorber 37 on the arm 2 1 when the overspeed switch 1 1 is actuated. Further, a lever 23 that operates in conjunction with the wrist 15 of the cable clamp 6 is rotatably provided on the rotating shaft 17. As shown in Figs. 1 to 5, unlike the prior art, the overspeed switch 11 is not operated due to the rotation of the lower link 1 〇b, and the lower link 1 Ob is rotated to make the arm 2 1 The rotational force generated by the falling of the cam 1 9 causes the overspeed switch 11 to be operated. 3( a ) ( b ) ( c ) is a side view of the overspeed switch 1 1 , respectively: the third ( a ) diagram shows the state before the arm 2 1 is dropped, and the third (b) The figure shows the state in which the overspeed switch 11 is actuated while the arm 2 1 is falling, and the third (c) diagram shows the state in which the overspeed switch 1 1 is reactivated by the lever 23 to maintain the operation. Next, the effect of the present embodiment formed by such a configuration will be explained. When the lower link 1 〇b is pulled upward as the centrifugal force of the pulley car 8 (see Fig. 12) increases, the rotating shaft 22 rotates to the right, so that the cams 19 fixed to the rotating shaft 2 2 are also interlocked. Rotate right. Therefore, the cam roller -11 - 1270522 (9) the shaft 20 is disengaged from the cam 19 to drop the arm 2 1 (Fig. 4). When the arm 21 is dropped, the over-speed switch 1 1 is smoothly operated by the face-down portion 21a of the arm 21, and the over-speed switch 1 1 is stably maintained in the state in which the side of the arm 2 1 is actuated (3 ( a ) (b) Figure). Further, when the centrifugal force of the pulley car 8 is increased, the link 24a fixed to the rotating shaft 22 rotates the link 25 fixed to the rotating shaft 25a to the left. At this time, the cam roller shaft 26 is disengaged from the link 25, and the wrist 15 of the cable clamp member 6 is lowered to actuate the cable clamp member 6. At this time, the wrist 15 of the cable clamp member 6 is connected to the rod 23 via the rotating shaft 17 , so that when the cable clamp member 6 is actuated, the lever 2 3 also rotates in the same manner as the wrist 15 , thereby making the overspeed switch 1 1 is again activated (Fig. 3 (c)). Therefore, even if the action of the arm 21 causes the overspeed switch to be uncut, the lever 23 can also actuate the overspeed switch 11. Thus, when the cable clamp member 6 is actuated, the overspeed switch 1 1 is cut off, as specified in the European specification (EN 8 1 -1). Therefore, the lower speed switch 1 1 can be indirectly operated by the cam 19, the arm 21, the additional cam 25 and the rod 23 by the lower speed control link 1 〇b, so that the lower speed control link 1 〇b The direct operation of the overspeed switch 1 1 becomes unnecessary, so that the action resistance of the overspeed switch 1 1 can be eliminated. Therefore, when compared with the prior art, the error factor of the fluctuation of the operating force of the overspeed switch 1 1 and the like can be eliminated, and the discontinuity of the operating force of the speed governing mechanism 5 can be made small (refer to FIGS. 15 and 16). ). The above-described technique is particularly effective in that it is necessary to make the change of the centrifugal force small and to adjust the adjustment mechanism 5 which is difficult. However, in Fig. 1, the load point of the cam roller shaft 20 provided on the arm 21 is on the vertical line of the center of the rotary shaft 22 of the cam 19, and the convex -12-1270522 (10) wheel 1 9 arc 1 The center of 9 a is consistent with the center of the shaft 2 2 . At this time, the weight of the roller shaft 20 and the arm 21 cannot transfer the torque to the rotary shaft 22 via the cam 19, and therefore does not become the rotational resistance of the rotary shaft 22. The operating force of the over-speed switch 1 1 and the amount of rotation of the cam 19 are continuously changed regardless of the arm 2 1 setting. Further, since the overspeed switch 1 1 is operated as described above, the operation of the overspeed switch 1 1 has no effect on the operating force of the configuration 5 . Therefore, the continuity of the operating force of the speed governing mechanism 5 can be maintained, so that the reliability can be further improved, and the speed regulating performance can be improved. When the overspeed switch 11 is actuated once, it is confirmed by a specialist. After the safety, the resetting operation is carried out manually. Although it is an essential obligation in Article 2, Section 2, 423 of the Ministry of Construction of Japan in Japan, it is also considered to implement automatic reset using the jump of the arm 2 1 . According to the present invention, the impact absorber 3 7 can be used to surely prevent jumping back. At this time, in consideration of the simple viewpoint of the structure of the inexpensive structure, or the jumpback of f, and the automatic resetting of the impact when the cable clamp member 6 is actuated, it is preferable to use the low elastic rubber as the impact absorber 3 7 . . Next, the modification of the present invention will be described with reference to Fig. 6 and Fig. 7, for example, as shown in Fig. 6(a) and (b), and after the arming 21 is actuated by the arm 21, the overspeed switch 1 1 can be prevented. A ratchet (arm ratchet) 27 is disposed around the target shaft 17 by mistake. The ratchet 27 is formed by a portion 27b on the side of the rotating shaft 17 and a portion fixed to the side of the arm 2 1 , and the points 2 7 a and 2 7 b are pressed against each other by the spring 28, and are convexly transmitted. Therefore, the position is indirect speed, so the technology is back on the 2nd and the f 21 t 21 may be opened at a speed of 27a. -13- 1270522 (11) Here, the figure 6(a) shows a plan view without a ratchet, and the figure 6(b) shows a side view. When the overspeed switch 11 is reset, the arm 2 1 is pulled forward and the gear of the ratchet 27 is not released, and the structure cannot be reset to prevent erroneous reset. Further, similarly to the ratchet wheel 27 shown in Fig. 6(a) and Fig. 6(b), the spring pin 2 9 may be provided around the rotating shaft 17 as in the case of the younger brother 7(a) and (b). Here, the 7th (a) diagram shows the diagram before the spring pin hole is engaged, and the 7th (b) diagram shows the diagram of the card engagement with the spring pinhole. In the present modification, when the arm 2 1 is rotated to the position where the overspeed switch 1 1 is actuated, the spring pin 2 9 attached to the arm 2 1 side is fitted into the hole 38 provided on the side of the rotating shaft 17 . At this time, the rear arm 2 1 cannot be rotated as long as the spring tongue 29 and the hole 38 are not released. Here, the spring pin mechanism and the hole 38 constitute a spring pin mechanism (arm spring pin mechanism). The installation cost of the spring pin 2 9 is generally considered to be between the impact absorber 37 and the ratchet 27 . As described above, when the rotation suppressing mechanisms 27, 29, and 38 are disposed on the arm 2, the erroneous reset of the overspeed switch 丨1 can be prevented. Next, a further modification of the present invention will be described with reference to Figs. 8 and 9. As shown in the figure 8 ( a ) ( b ), a ratchet (cam ratchet) 3 2 may be provided around the shaft 2 2 . The ratchet 32 is formed by a portion 3 2 b fixed to the side of the rotating shaft and a portion 3 2 a fixed to the side of the base 33, and the portions 3 2 a (12) 1270522 and 3 2b are pressed against each other by the spring 34. Keep it. Here, the 8th (a) diagram shows the plan view of the ratchet, and the 8th (b) diagram shows the side view of the ratchet. In the present modification, even if the arm 2 1 is jumped back, the cam 19 does not receive the arm 2 1 , so there is no problem that the over-speed switch 11 is reset. The reset of the overspeed switch 构造 is a structure in which the arm 2 1 is pulled forward and the gear of the ratchet 27 is not removed, and the structure cannot be reset. The operating force of the ratchet 3 2 can be made small by the strength of the spring 34 and the height and angle of the ratchet 32, so that it is resistant to the degree of reverse rotation of the cam 19. Therefore, setting the ratchet 3 2 has little effect on the continuity of the operating force of the overspeed switch 1 1 . Further, as shown in Fig. 9(a)(b), in order to prevent the erroneous reset of the overspeed switch 11 in the same manner, a spring pin mechanism (arm spring pin) formed by the cam 35 and the spring pin 36 may be provided. mechanism). In the figure 9 ( a ) ( b ), the cam 3 5 coupled to the rotary shaft 2 2 rotates to the right along with the cam 1 9 . When the cam 19 is rotated to disengage the cam roller shaft 20 from the cam 19 and the arm 21 is dropped, the spring pin 36 provided on the base 33 side is fitted to the cam 35. When the spring pin 36 is fitted to the cam 35, although the cam 35 can continuously rotate to the right together with the cam 19, it cannot rotate to the left together with the cam 1 9 and falls toward the arm 2 1 return. Therefore, the erroneous reset of the overspeed switch 1 1 can be prevented. Further, when the ball or the like is inserted into the front end of the spring pin 36, the sliding resistance can be made to be rotationally resistant, so that the discontinuous point of the operating force can be made extremely small -15-(13) 1270522, and the BRIEF DESCRIPTION OF THE DRAWINGS A further modification of the present invention will be described. In the embodiment shown in Figs. 1 to 5, an example is shown in which the weight 3 0 is provided on the arm 2 J, and the length of the arm 2 1 is made short, thereby achieving an inexpensive space saving. It is not limited thereto, and as shown in FIG. 10, the spring 3 1 may be used instead of the weight 30 to increase the rotational force of the arm 2 1 . In Fig. 10, the pressing spring 3 1 can be used in accordance with the installation space. When the spring 31 is used, the force of the arm 2 1 can be increased more than when the weight 30 is used.
