【０００１】
【発明の属する技術分野】
本発明は、幹線道路や高速道路等の中央分離帯を有する道路における車輌誘導技術に関し、更に詳しくは、災害や事故などに基づく交通規制の際、前記道路上を走行する車輌を安全且つ迅速に対向車道側へ誘導する車輌誘導方法、並びに旋回ゲート装置及び開閉ゲート装置に関する。
【０００２】
【従来の技術】
災害、事故等の非常事態が発生した場合、一般道路は勿論、高速道路や幹線道路上を走行する車輌は、必然的に大渋滞に巻き込まれる。前記幹線道路や高速道路の多くは、非常時における緊急車輌専用道路に指定されており、前記の如く非常事態が発生した場合には、当該道路の各進入口において、警察官その他の誘導要員による車輌通行止めや料金所ゲートの閉鎖等が行なわれ、一般車輌の進入が完全に阻止される。
しかしながら、前記幹線道路や高速道路には通常、走行車輌の対向車道側への逸脱や移動を防止する防護体が固定された中央分離帯が設けられており、従って例えば災害地域或いは事故現場に向かって上り側車道において既に停滞している各車輌は、下り側車道に迂回してＵターンすることもできず、前記道路の交通麻痺状態は長期にわたって継続する。
そして、この様な交通麻痺の状態においては、近隣他府県からの緊急消防消火活動の支援車輌、救急救援車輌、食料や支援物資輸送車輌、事故処理車輌などの緊急車輌が、災害地域又は事故現場へ急行することは不可能であり、この救援活動の遅れが被害を拡大させる一因となっていた。
【０００３】
一方、特開平４−２１３６０６号公報には、図１９に示すように道路の中央分離帯５００の途中部に設けられる除去可能な防壁５０２、５０２であって、交通事故や交通渋滞の際には、該防壁を道路と平行に移動させ、一方の車道５０３ａを走行している車輌が対向車道５０３ｂ側に出ることのできる通路５０１を形成するものが開示されている。この様に、中央分離帯に通路を形成し、該通路５０１を介して上記停滞している車輌を対向車道側へ迂回させれば、交通の麻痺状態を徐々に解消させることは可能である。
【０００４】
【発明が解決しようとする課題】
しかし、前記通路５０１を介して、上り側車道の車輌を下り側車道の交通に安全且つスムーズに合流させる為には、多くの誘導要員や、誘導器具、誘導車輌、これら要員及び器具を運搬する車輌等の人的、物的要素が、前記通路及びその周辺に必要であり、事故又は災害が発生してから交通渋滞が起こる前にこれら誘導を開始することは事実上困難であるとともに、幹線道路や高速道路上での誘導には多大な危険を伴う。そして、誘導が効果的に為されるまで上り側車道の混乱は継続することとなり、道路の麻痺状態を迅速に解消して当該道路を短時間のうちに緊急車輌専用道路に変換するといった目的を達成するには限界があった。
【０００５】
本発明は係る現況に鑑み為されたもので、災害や事故等が発生した際、中央分離帯を有する幹線道路や高速道路上において前記災害地域又は事故現場等の規制区域に向かって上り側車道を走行する車輌を、安全且つ迅速に下り側車道へ誘導することで、当該道路から一般車輌を迅速に排出し、早急に緊急車輌専用道路に変換できる車輌誘導技術を提供せんとするものである。
【０００６】
【課題を解決するための手段】
すなわち本発明は、直立する旋回中心軸と、前記旋回中心軸に端部を支持された状態で旋回する遮断部材と、遮断部材の旋回半径方向の先端部に設けられた、路面上を転動する駆動輪と、遮断部材の長手方向途中部に設けられ、前記駆動輪と共に該遮断部材の全荷重を支持する遊動輪と、前記駆動輪を駆動する駆動手段と、この駆動手段に電力を供給する給電手段とより構成され、前記遮断部材が自立して前記旋回中心軸周りに旋回走行し、該遮断部材が、車輌進行を阻止する位置と該車輌進行阻止状態を解除する通常位置との間で二位置的に旋回してなる旋回ゲート装置を提供する。
【０００７】
特に、前記旋回中心軸が車道に隣接して立設され、該旋回中心軸にその端部を支持された状態で旋回する遮断部材が、車道上に旋回突出することで車輌進行を阻止する位置と、逆方向に旋回して車道に平行となり、通行阻止状態を解除する通常位置との間で二位置的に旋回駆動される旋回ゲート装置を提供する。
【０００８】
また、直立する旋回中心軸と、前記旋回中心軸に端部を支持された状態で旋回する２つの遮断部材と、各遮断部材の旋回半径方向の先端部に設けられた、路面上を転動する駆動輪と、各遮断部材の長手方向途中部に設けられ、前記駆動輪と共に各遮断部材の全荷重を支持する遊動輪と、前記駆動輪を駆動する駆動手段と、この駆動手段に電力を供給する給電手段とより構成され、各遮断部材が、それぞれ独立して、自立して前記旋回中心軸周りに旋回走行し、各遮断部材が、車輌進行を阻止する位置と、該車輌進行阻止状態を解除する通常位置との間で二位置的に旋回してなる旋回ゲート装置を提供する。
【０００９】
これら旋回ゲート装置は、遮断部材の先端部に駆動手段を設けたことで、テコの原理に基づく僅かな動力により当該遮断部材を確実に旋回させることが可能となり、且つ旋回中心軸には強力なヒンジ構造が不要となり、単に遮断部材を回転可能に支持する簡単な構造を採用できる。また、遮断部材は先端部に設けた駆動輪により駆動されるため、レールや案内ガイド等の旋回案内部を設ける必要もなく、極めて短期間且つ低コストで設置可能となる。また、遮断部材の長手方向途中部に、前記先端部の駆動輪と共に該遮断部材の全荷重を支持する遊動輪を設け、これら駆動輪及び遊動輪により前記遮断部材が自立して旋回走行するので、遮断部材の端部を回転可能に支持している旋回中心軸には、当該遮断部材を旋回させるための駆動手段は勿論のこと、遮断部材の荷重が作用しないため該遮断部材の荷重を支持する支持強度も不要であり小さなものが採用でき、また、これを固定する基礎材も、軽量且つ小型のものが採用でき、基礎工事や据付工事が簡単になる。また、前記旋回中心軸の強度にかかわらず、長い遮断部材や上述の鋼管溶接構造の本体フレームからなる遮断部材も採用できる。
【００１０】
ここで、前記遮断部材が、断面視三角形の各頂点位置にそれぞれ配された長手方向に延びる主鋼管と、これら主鋼管をトラス状に連結するトラス管とより構成される鋼管溶接構造の本体フレームからなるものでは、該遮断部材が軽量且つ堅牢な構造となり重心が低く、車輌の衝突や人為的な破壊行為、いたずら行為等にも充分に耐え得るとともに、風圧を逃がすことが可能となり、台風等の強風にも充分耐え得る構造にすることができる。
【００１１】
前記本体フレームの表面には、亜鉛メッキ仕上げのうえ粉体塗装を施し、排気ガスその他の汚れが脱落容易に処理されることが好ましい。
【００１２】
前記遮断部材の先端部には、ローラチェーンにより同調駆動される複数の駆動輪が設られ、これら駆動輪は、耐磨耗性及び耐暑耐寒性に優れたウレタン系のソリッドゴムタイヤからなるものが、天候に左右されず路面上を常時静寂且つ滑らかに転動する点で好ましい。
【００１３】
また、駆動輪の設置角度は、車輪の軸方向が旋回中心軸を通る旋回半径の方向に一致するように設定され、遮断部材の旋回動作に基づいて旋回中心軸に過大な横力が作用するといったことも回避されている。
【００１４】
また、前記遮断部材の先端部には、前記駆動手段として前記駆動輪に駆動力を伝動する駆動モータ及び歯車減速機が設けられ、前記駆動手段は、手動により遮断部材を旋回させる手動旋回機構を備えていることが好ましい。
【００１５】
具体的には、歯車減速機の出力軸先端に、手動旋回機構としてクラッチ及び該クラッチの動力伝達を遮断するためのクラッチレバーを設け、前記クラッチレバーを操作することで人力による旋回動作を可能としたものが好ましい実施例である。これにより、万一駆動手段や電力供給手段等に不具合が生じた場合も、前記クラッチレバーを操作して動力伝達を遮断させることで、遮断部材が人力により旋回動作可能となり、混乱を生じることなく前記遮断部材を柔軟且つ確実に旋回させることが可能となる。
【００１６】
また、前記給電手段がバックアップ電源として二次電池を備え、且つ駆動手段の駆動モータが直流モータであれば、主電源が遮断されても、旋回ゲート装置を相当回数作動させることが可能となる。
【００１７】
【発明の実施の形態】
次に、本発明を添付図面に基づき詳細に説明する。
【００１８】
図１〜５は本発明の技術的思想を示す概念図である。図中１０１は道路の中央分離帯１００の適所において対向車道側へ車輌を通過させる開所、１０２は前記開所を駆動手段により開閉自在に閉鎖する閉止装置をそれぞれ示している。
【００１９】
図１は、本発明に係る車輌誘導方法を説明する概念図である。
通常時、開所１０１は図１（ａ）に示す如く閉止装置１０２により車輌通行不能に閉鎖されている。前記閉止装置１０２は図示しない駆動手段を備えており、災害や事故等の発生に基づく交通規制の際には管制センター等による遠隔操作や、現場に急行した１〜３人程度の警察官等の操作員による現場操作、又は現場周辺に設けた各種検知器の信号に基づく自動制御により、始動その他の誘導動作が為される。そして、この様に閉止装置１０２、又は別途規制装置を設ける場合には閉止装置１０２並びに当該規制装置が駆動されることにより、多数の誘導要員や誘導器具等を用意することなく、図中道路左側に斜線領域で示す規制区域に向かって上り側の車道１０３を進行する車輌１０５ａが迅速且つ安全に下り側車道１０４へ誘導され、道路上の各車輌１０５ａ、１０５ｂは渋滞することなく短時間のうちに道路外へ排出されるのである。
ここに、前記規制区域とは災害や事故等が発生した方面の区域を指し、一般車輌の進入が規制される区域をいう。
【００２０】
災害又は事故の状況や規制の区域、開所１０１の正確な位置、誘導方法等の誘導に関する各種案内情報や警告情報は、前記開所１０１に対し進行方向手前側における車道１０３、１０４に沿った適宜な位置に設けられ且つ文字情報を電光表示する電光掲示板や、同じく適宜な位置に設けられ且つ車載ナビゲーション装置を介して地図情報や簡略地図情報、文字情報、音声情報等を伝達するビーコン局などによって、車輌１０５ａ、１０５ｂのドライバーに認知される。ここで、霧等の悪天候や朝夕の時間帯、道路の形状、構造等により前記電光掲示板や開所１０１の見通しが悪い状況や、ドライバーの集中力が低下している状況等を考慮すれば、同じく開所１０１手前側の適宜な位置に、上端の閉口した単又は複数の筒体を路面に対し出没させる後述の昇降装置１７を埋設しておき、交通規制の際には前記筒体を路面より僅か上方に突出させ、その上面を通過した車輌運転者の身体に振動を与えることで非常事態を強制的に認識させることが好ましい。
【００２１】
次に、上記閉止装置１０２を用いて上り側車道を走行する車輌１０５ａを下り側車道１０４へ誘導する手順を説明する。交通規制の際には、先ず図１（ｂ）に示すように、上り側車道１０３における前記開所１０１の少なくとも１車輌幅を有する通行部位１０６が進行方向手前側となる位置１０７で、当該上り側車道１０３の車輌１０５ａの進行を阻止して通行止めにする。そして、これ以後は以下に示す第１誘導過程と第２誘導過程とを交互に繰り返して行う。
【００２２】
即ち、図１（ｃ）に示す如く、前記開所１０１における少なくとも前記進行部位１０６を開放して、前記上り側車道１０３で進行を阻止された車輌１０５ａを当該通行部位１０６を介し図中鎖線矢印の如く下り側車道１０４へ誘導するとともに該下り側車道１０４における前記通行部位１０６より進行方向手前側の適宜な位置１０８で当該下り側車道１０４の車輌１０５ｂの進行を阻止する第１誘導過程と、図１（ｄ）に示す如く、前記開所１０１における少なくとも前記通行部位を閉鎖し、車輌１０５ａの前記下り側車道１０４への通行を阻止するとともに該下り側車道１０４における車輌１０５ｂの通行阻止の状態を解除する第２誘導過程とを、交互に繰り返し行うのである。
【００２３】
本発明では、このように上り側車道１０３と下り側車道１０４の各車輌１０５ａ、１０５ｂを交互に誘導するので、下り側車道１０４に誘導された車輌１０５ａが該車道を走行してきた車輌１０５ｂと接触又は衝突するといった事故が未然に防止でき、誘導時の安全性を維持することができる。ここで、前記上り側車道１０３及び下り側車道１０４のそれぞれにおける開所１０１に対して進行方向手前側の適宜な位置に車輌検出手段又は速度検出手段を設置すれば、上記管制センターにおいて閉止装置１０２を遠隔操作する際に道路状況を確認して車輌に対する安全性を向上でき、さらには前記車輌検出手段や速度検出手段で得られる道路状況に基づいて前記閉止装置１０２の駆動を制御すれば、上記２つの誘導過程をより効率良く行うことができる。
【００２４】
前記閉止装置１０２としては、後述する昇降装置や開閉ゲート装置、昇降する遮断桿を有する遮断装置、チェーンゲート装置等の様々な形態の装置を採用できるが、特に、前記開所１０１に立設した共有若しくは独自の旋回中心軸を中心に回動して上り側車道１０３又は下り側車道１０４に旋回突出される複数の遮断部材を備え、該遮断部材の一旋回動作により開所１０１の開放と車道１０３又は１０４の車輌進行阻止を同時に達成可能な旋回ゲート装置を単独若しくは他の装置に併設して用いることが好ましい。
【００２５】
例えば、図２は、旋回ゲート装置１１１Ａを用いた車輌誘導方法の概念図を示している。該旋回ゲート装置１１１Ａは、開所１０１の略中央部に立設される旋回中心軸１０９と、該旋回中心軸１０９にその端部を支持された状態で旋回する２つの遮断部材１１０ａ、１１０ｂと、各遮断部材を独立に旋回駆動させる図示しない駆動手段と、この駆動手段に電力を供給する図示しない給電手段とを備え、通常時には図２（ａ）に示す如く、前記２部材１１０ａ、１１０ｂを道路に平行な一直線状に配置させて開所１０１を閉鎖している。
【００２６】
ここに、前記旋回中心軸には、自身は回転せず単に遮断部材の回動を支持するものと、遮断部材と一体回転してトルクを伝達する伝動軸として機能するものが含まれ、また、遮断部材の荷重を支持するものと、支持しないものが含まれる。
【００２７】
また、前記２つの遮断部材は、開所の略中央部に設けた１つの旋回中心軸を共有して、それぞれ該旋回中心軸に端部を支持された状態で独立に旋回するものと、開所の略中央部に並設した２つの独自の旋回中心軸にそれぞれ端部を支持された状態で独立に旋回するものが含まれる。
【００２８】
そして、前記旋回ゲート装置１１１Ａは、交通規制の際、先ず図２（ｂ）に示す如く、前記旋回中心軸１０９に対して上り側進行方向に位置する上り側遮断部材１１０ａを図中鎖線矢印のように旋回駆動させて上り側車道１０３における車輌１０５ａの進行を突出阻止し、以後、図２（ｃ）に示す如く、他方の下り側遮断部材１１０ｂを図中鎖線矢印のように旋回駆動させて、通行部位１０６を開放するとともに下り側車道１０４の車輌１０５ｂの進行を阻止する第１誘導過程と、図２（ｄ）に示す如く、前記下り側遮断部材１１０ｂを通常位置まで逆方向に旋回駆動させて、前記通行部位を閉鎖するとともに下り側車道１０４の進行阻止状態を解除する第２誘導過程とを交互に繰り返し行うのである。
この様な旋回ゲート装置１１１Ａを用いた車輌誘導方法によれば、各遮断部材１１０ａ、１１０ｂが車道に旋回突出する際、旋回中心軸１０９に対し車輌進行方向奥側に位置する部材が、その先端方向を接近する走行車輌に対して鈍角に維持しつつ当該車道に進入するため、前記車輌の運転者にとって視認が容易であり、万一前記部材に衝突しても当該車輌は部材側面に衝突するので対向車道側に飛び出し大惨事を引き起こすといった危険性はない。尚、各遮断部材１１０ａ、１１０ｂの表面には誘導に関する案内情報を文字や矢印等により電光表示する情報表示部を設けておくことが好ましく、例えば、一方の遮断部材１１０ａの表面では、暫く停止すべき旨と通行部位を通過すべき旨が切替え表示され、他方の遮断部材１１０ｂの表面では、暫く停止すべき旨と直進すべき旨が切替え表示されることが好ましい。
【００２９】
また、同様の趣旨のものとして図３に示す旋回ゲート装置１１１Ｂは、開所１０１に臨む中央分離帯１００の端部１１２、１１３において、車道１０３、１０４にそれぞれ隣接して立設される２本の旋回中心軸１０９ｃ、１０９ｄ及び１０９ｅ、１０９ｆと、各旋回中心軸にその端部を支持された状態で旋回する４つの遮断部材１１０ｃ、１１０ｄ、１１０ｅ、１１０ｆと、各遮断部材を独立に旋回駆動させる図示しない駆動手段と、この駆動手段に電力を供給する図示しない給電手段とを備え、通常時には、図３（ａ）に示す如く、上り側車道１０３に面し且つ進行方向手前側に位置する上り線第１部材１１０ｃと、同じく進行方向奥側に位置する上り線第２部材１１０ｄと、下り側車道１０４に面し且つ進行方向手前側に位置する下り線第１部材１１０ｅと、同じく進行方向奥側に位置する下り線第２部材１１０ｆとからなる４つの遮断部材をそれぞれ道路と平行に配置させることで前記開所１０１を閉鎖している。
【００３０】
この旋回ゲート装置１１１Ｂによる交通規制時における好ましい動作手順は、先ず図３（ｂ）に示す如く、上り線第１部材１１０ｃを旋回駆動させて上り側車道１０３における車輌１０５ａの進行を突出阻止するとともに上り線第２部材１１０ｄを同じく上り側車道１０３に旋回駆動させ、以後、図３（ｃ）に示す如く、上り線第１部材１１０ｃを通常位置まで逆方向に旋回駆動させて上り側車道１０３の進行阻止状態を解除し、且つ下り線第１部材１１０ｅを旋回駆動させて通行部位１０６を開放するとともに下り側車道１０４の車輌１０５ｂの進行を阻止する第１誘導過程と、図２（ｄ）に示す如く、前記上り線第１部材１１０ｃを旋回駆動させて上り側車道１０３における車輌の進行を阻止し、且つ下り側第１部材１１０ｅを通常位置まで逆方向に旋回駆動させ、通行部位１０６を閉鎖するとともに下り側車道１０４の進行阻止状態を解除する第２誘導過程とを交互に繰り返して行うことが好ましい。
【００３１】
尚、前述の旋回ゲート装置１１１Ａの場合と同様に、各遮断部材の表面には誘導に関する案内情報を電光表示する情報表示部を設けることが好ましく、例えば、車道上に旋回突出することで車輌進行を阻止する遮断部材１１０ｃ、１１０ｅの前記情報表示部では、暫く停止すべき旨と進行すべき旨が切替え表示され、車輌１０５ａを通行部位１０６へ誘導する遮断部材１１０ｄの情報表示部では、矢印で通行部位１０６の方向が表示されることが好ましい。
また、前記手順において、誘導開始時の上り線第１部材１１０ｃと上り線第２部材１１０ｄの旋回動作は、同期動作と差動動作の何れでも良く、特に差動動作させる場合には車輌の安全を考慮し、先端方向が接近する走行車輌に対して鈍角を維持しつつ車道に突出する上り線第１部材１１０ｃを先に旋回させることが好ましい。同様に、前記２過程の交互誘導時における上り線第１部材１１０ｃと下り線第１部材１１０ｅの旋回動作も同期動作と差動動作の何れでも良く、特に差動動作させる場合は、上り側車道に突出している遮断部材１１０ｄと旋回される遮断部材１１０ｃとの間に車輌１０５ａが挟まれることを防止するため、各過程において車輌の進行を阻止する部材、即ち、上記第１誘導過程にあっては下り側第１部材１１０ｅ、第２誘導過程にあっては上り側第１部材１１０ｃをそれぞれ先に旋回突出させることが好ましい。
また、上記一連の誘導動作において、上り側車道１０３の車輌１０５ａの進行阻止又は阻止解除は上り線第１部材１１０ｃの旋回往復動作により繰り返し行われるが、例えば、この上り線第１部材１１０ｃは前記上り線第２部材１１０ｄの旋回突出完了後に逆旋回させ通常位置まで戻しておき、以後の上記２過程の交互誘導を下り線第１部材１１０ｅの旋回動作により行えば、消費電力を節減できる点で好ましい。
【００３２】
以上の旋回ゲート装置１１１Ｂにおいては、２つの遮断部材１１０ａ、１１０ｂからなる上述の旋回ゲート装置１１１Ａの場合と同様、高い安全性が維持できるとともに、前記旋回ゲート装置１１１Ａでは必要以上に長い遮断部材が必要となる幅広な中央分離帯に設ける場合であっても、車道幅に応じた適尺な遮断部材を用いることが可能である。
【００３３】
ところで、以上に示した各車輌誘導方法に用いられる旋回ゲート装置１１１Ａ、１１１Ｂは、それぞれ遮断部材を車道に略直角方向に旋回突出して当該車道上の車輌の進行阻止を行う関係上、前記遮断部材の長さは車道の幅に対応した寸法に適宜設定されている。したがって車道幅の狭い片側１車線程度の道路において、上記図２又は図３に示すように旋回ゲート装置１１１Ａ又は１１１Ｂを単独で用いて開所を閉鎖する場合には、遮断部材の旋回動作に基づき開放される通行部位１０６の幅も前記１車線程度の幅となり、この幅は、バスやトラック等の大型車輌が迅速且つスムーズに通行するには充分な大きさとならない場合がある。
【００３４】
このような場合には、図４に示す如く、開所１０１を閉鎖する閉止装置１０２として、前記旋回ゲート装置１１１Ａと別途構成した開閉ゲート装置１１６を併設構成し、前記通行部位１０６の幅を遮断部材の長さ以上に拡大可能とすることが好ましい。即ち、閉止装置１０２は、前記開所１０１に臨む中央分離帯の両端１１２、１１３から、それぞれ開所１０１空間内に道路の長手方向に沿って移動する２つの閉鎖部材１１４、１１５と、各閉鎖部材を独立に駆動させる図示しない駆動手段と、この駆動手段に電力を供給する図示しない給電手段とを備えた開閉ゲート装置１１６を、上記旋回ゲート装置１１１Ａに併設してなり、通常時には、図４（ａ）に示すように、前記旋回ゲート装置１１１Ａの２つの遮断部材１１０ａ、１１０ｂを道路に平行な一直線状に配置させ且つ開閉ゲート装置１１６の２つの閉鎖部材１１４、１１５を前記中央分離帯の両端から開所１０１空間内に突設することで、前記開所１０１を車輌通行不能に閉鎖している。そして、前記旋回ゲート装置１１１Ａの誘導動作の手順は上述したものと同様であるが、図４（ｂ）に示す如く、前記旋回ゲート装置１１１Ａの下り側遮断部材１１０ｂに連動して開閉ゲート装置１１６の下り側進行方向に位置する閉鎖部材１１５が下り側進行方向に移動し、開所空間外の中央分離帯１００に重装されることで前記通行部位１０６の開放幅を拡大するのである。
【００３５】
尚、前記開閉ゲート装置１１６は、旋回ゲート装置１１１Ａと独立して駆動可能に構成しておけば、該開閉ゲート装置１１６だけを作動させることで車道における一般車輌の走行に支障を来すことなく緊急車輌や工事車輌のみ開所を通過させることが可能となる。
【００３６】
ここで、以上図２〜図４に示した閉止装置１０２は、開所に対して何れの方面が規制区域となっても容易に対応できるよう道路の長手方向に沿って対称に構成されているが、例えば前記開所をトンネル内の事故若しくは崩落にそなえて設ける場合や下り側車道が道路出口の直前となる位置に設ける場合など、作動対象となる規制区域の方向が予め一方向に決定される場合には、以下に示すような非対称の構成としても良い。
【００３７】
即ち、図５（ａ）は、図中左側の斜線領域で示したトンネル内の事故若しくは崩落にそなえて設けられる非対称の旋回ゲート装置１１１Ｃの概念図を示しており、当該旋回ゲート装置１１１Ｃは、開所１０１を臨む中央分離帯１００のトンネル側端部１１２に立設される旋回中心軸１０９ｇと、該旋回中心軸１０９ｇにその端部を支持された状態で旋回される１つの遮断部材１１０ｇと、該遮断部材を旋回駆動させる図示しない駆動手段と、この駆動手段に電力を供給する図示しない給電手段とを備え、前記遮断部材１１０ｇは、トンネルに向かって上り側の車道１０３における前記開所１０１が進行方向手前側となる位置１０７で車輌１０５ａの進行を阻止する昇降装置１１７の昇降動作と連動して、旋回駆動される。
【００３８】
前記昇降装置１１７の実施例としては、特許公報第２８６１９５２号記載の車輌通行規制装置、即ち図１７に示す昇降装置１７が好適に採用される。即ち、前記昇降装置１７は、本体部１８が車道の地中に埋設され、路面を構成する上板１９より上方に突出した位置において車輌進行路幅を実質的に狭め車輌進行を阻止する上昇位置と、路面付近に下降した位置において前記車輌進行を阻止しない下降位置との間を二位置的に昇降する上端の閉口した単又は複数の筒体２０と、該筒体２０を昇降駆動させる駆動手段と、この駆動手段に電力を供給する給電手段とを備え、筒体２０が車輌１０５ａの走行を規制する規制部材１２０として直接作用する。
【００３９】
そして、交通規制時における前記旋回ゲート装置１１１Ｃ及び昇降装置１１７の動作は、先ず前記昇降装置１１７の規制部材１２０、…を上昇位置に移動させて上り側車道１０３の車輌進行を阻止した後、旋回ゲート装置１１１Ｃの遮断部材１１０ｇを下り側車道１０４に旋回駆動させて通行部位１０６を開放するとともに下り側車道１０４の車輌の進行を阻止する第１誘導過程と、前記遮断部材１１０ｇを通常位置まで逆方向に旋回駆動させて、前記通行部位１０６を閉鎖するとともに下り側車道１０４の進行阻止状態を解除する第２誘導過程とを交互に繰り返し行うのである。尚、ここで前記遮断部材１１０ｇの先端側に１つの閉鎖部材を有する開閉ゲート装置を併設しておけば、通行部位１０６をさらに拡大することが可能である。
【００４０】
また、同様の趣旨として図５（ｂ）に示す如く、同じく図中左側の斜線領域で示したトンネル内の事故若しくは崩落にそなえて開所１０１に設けられ、旋回ゲート装置１１１Ａと該装置に対し下り側進行方向にのみ閉鎖部材１１５を備えた開閉ゲート装置１１６Ｃとからなる非対称な開閉装置１０２を構成すれば、前記閉鎖部材１１５の移動により通行部位１０６を拡大することができる。
【００４１】
本発明の車輌誘導方法は道路の車線の数に何ら制約を受けるものではなく、片側３車線以上の幅広な道路の場合には、前記旋回ゲート装置の遮断部材を長尺に設定することでこれに対応でき、または別途構成した規制装置を道路側方に併設することで遮断部材による車輌進行阻止機能を補うものであっても良い。このような規制装置には、通常時に中央分離帯の防護体として用いられる上述した各旋回ゲート装置程の高い衝撃強度は特に必要でなく、上記図１７に示した昇降装置１７の他に、同じく駆動手段及び給電手段を備えた旋回ゲート装置や開閉ゲート装置、遮断装置、チェーンゲート装置、その他の車輌進行抑止機能を有する装置全般が好適に採用できる。
【００４２】
尚、一般車輌の誘導中であっても、上り側の路肩を含む道路側方においては緊急車輌が進行可能となる通行空間を確保することが好ましく、例えば旋回ゲート装置の各遮断部材の長さを、その先端部と道路側端との間に前記通行空間が形成される寸法に設定したり、道路側方に上記昇降装置等の規制装置を設ける場合にあっては、緊急車輌から発信される無線信号に基づき前記規制装置を一時開放させることが好ましい。また、緊急車輌が道路の側方をよりスムーズに進行する為には、上り側車道に設けた前述の電光掲示板やビーコン局において、一般車輌に対し進行方向右側に車輌を寄せて停止する旨の案内情報を表示若しくは無線送信することが望ましい。
【００４３】
本発明では、以上の如き車輌誘導方法を採用することで、従来図１９に示した防壁５０２等では為し得なかった無人若しくは小人数の操作員による安全且つ迅速な車輌の誘導が可能となり、当該道路は短時間のうちに緊急車輌専用道路に変換されるため規制区域に向かう緊急車輌は道路上で渋滞に巻き込まれることはなく、災害地域や事故現場で迅速な救援活動を行なうことが可能となる。また、本発明の車輌誘導方法に採用される上述の対称若しくは非対称な各旋回ゲート装置や開閉ゲート装置を、幹線道路の交差点に臨む中央分離帯端部箇所に設けておけば、該交差点に進入する車輌を反対側車道へ誘導して当該道路を逆行させたり、前記交差点から該道路に向かって進入する車輌を確実に阻止することができ、災害、事故その他の道路状況に応じて交通をコントロールすることが容易となる。
【００４４】
また、旋回ゲート装置及び開閉ゲート装置は、給電手段を共用している場合が含まれる。
【００４５】
次に、上述の車輌誘導方法を実現する具体的な実施形態を示した図面に基づき、本発明を更に詳細に説明する。図６〜１７は本発明の第１実施形態、図１８は第２実施形態を示し、図中５は中央分離帯、１１は旋回ゲート装置をそれぞれ示している。
【００４６】
先ず、本発明の第１実施形態を説明する。図６は高速道路上に設けた旋回ゲート装置１１を示す説明図である。
【００４７】
旋回ゲート装置１１は、中央分離帯５に設けられた開所１の略中央部に直立する支柱７と、該支柱７を旋回中心軸として端部を支持された状態で旋回する２基の遮断部材１０ａ、１０ｂと、各遮断部材を独立に旋回駆動させる駆動手段８と、この駆動手段に電力を供給する給電手段４０とを備えている。
【００４８】
遮断部材１０ａ、１０ｂは、それぞれ長さ５〜１５ｍ、幅０．８〜２ｍ、高さ１．４〜１．７ｍ程の鋼管トラス構造の本体フレーム１２を有しており、上記寸法は道路幅その他の状況に応じて適宜自由に設定される。前記本体フレーム１２は、詳しくは図７乃至図９に示す如く、断面視三角形の各頂点位置にそれぞれ配された口径１５０ｍｍの長手方向に延びる主鋼管１２ａ、１２ｂ、１２ｃと、これら主鋼管をトラス状に連結する口径７５〜１００ｍｍのトラス管１３、…とからなる重心の低い鋼管溶接構造であり、台風や強風等の風圧は勿論のこと、車輌の衝突や人為的な破壊行為、いたずら行為等にも充分に耐え得る堅牢な構造を有する。尚、前記本体フレーム１２の表面は、亜鉛メッキ仕上げのうえ粉体塗装が施され、排気ガスその他の汚れが脱落容易に処理されている。
【００４９】
また、前記本体フレーム１２の長手方向に沿った適宜な複数箇所には姿勢保持手段２４として、図１０に示す如く、当該本体フレーム１２に固定されたスライド案内部材２１、該スライド案内部材の貫通孔２１ａにスライド自在に挿通した横長なストッパー部材２２、及び該ストッパー部材２２をワイヤー巻き上げ方式で上下に進退させる減速機付きモータ２３が設けられ、通常時には、前記ストッパー部材２２に対応する開所路面上に開口した支持孔２５に当該ストッパー部材２２を嵌入しておくことで、前記本体フレーム１２が該ストッパー部材２２を介し開所路面と一体化され、車輌衝突による移動が確実に阻止される。したがって各遮断部材は、通常時において車道に飛び出すことなく道路と平行な姿勢を維持し、強固な防護体として中央分離帯の機能を果たすのである。
【００５０】
本体フレーム１２の旋回半径方向、即ち長手方向の先端部２６には駆動手段３４として、図１１に示す如く、支柱を中心に本体フレーム１２を旋回駆動させる２個の駆動輪２７、２８、及び横軸３段の歯車減速機２９を介してローラチェーン３０、３１、３２により各駆動輪２７、２８に駆動力を伝動する直流モータ３３が設けられ、前記各駆動輪２７、２８はローラチェーン３２により同調駆動されるとともに前記歯車減速機２９及び直流モータ３３は取外し可能な駆動ケース３５内に収納される。そして、前記歯車減速機２９の出力軸先端には手動旋回機構として図示しないクラッチ及びクラッチレバーが設けられ、交通規制の際、万一駆動手段３４や電力供給手段４０等に不具合が生じた場合でも、前記駆動ケース３５を取外して前記クラッチレバーを操作しローラチェーン３１への動力の伝達を遮断させることで、各遮断部材は人力による旋回動作が可能となり、混乱を生じることなく前記各遮断部材を確実に旋回させることが可能である。
また、前記本体フレーム１２には、各駆動輪２７、２８と共に遮断部材の全重量を支持する２個の遊動輪３６、３７が設けられており、前記各駆動輪２７、２８及び遊動輪３６、３７はそれぞれ耐磨耗性及び耐暑耐寒性に優れたウレタン系のソリッドゴムタイヤからなり、天候に左右されず路面上を常時静寂且つ滑らかに転動する。
【００５１】
前記本体フレーム１２の上部には、旋回半径方向に沿った所定間隔毎に、それぞれ交通規制の際点滅される警告灯３８が設けられており、さらに該本体フレーム１２の表面には、誘導に関する案内情報を表示する電光表示部を設けることが好ましい。
【００５２】
以上の如き旋回ゲート装置１１にあっては、各遮断部材１０ａ、１０ｂの先端部２６に駆動手段３４を設けたことにより、テコの原理に基づく僅かな動力で当該各遮断部材を確実に旋回させることが可能となり、さらに駆動輪２７、２８と遊動輪３６、３７で各遮断部材の全荷重を支持しているので、該遮断部材は自立自走して旋回駆動されることとなり、その端部に設けた支持部４３を回転可能に支持する直径１００〜１５０ｍｍの金属製の支柱７には、遮断部材を旋回させる駆動手段は勿論のこと、該遮断部材を支持する支持強度も不要となる。また、各遮断部材に設けた前記駆動輪２７、２８及び遊動輪３６、３７のそれぞれの設置角度は、各車輪の軸方向が支柱７を通る旋回半径の方向に一致するように設定されており、遮断部材の旋回動作に基づき前記支柱７に過大な横力が作用することも回避されている。
【００５３】
前記姿勢保持手段２４の減速機付きモータ２３や駆動手段３４の直流モータ３３には、支柱７を介して道路側方から外部電力が供給され、同じく道路側方にはバックアップ電源として前記外部電力により常時充電されている二次電池が後述する制御装置３９内に設けられる。さらに、遮音壁等の道路外側面には、前記外部電力の遮断に備えて前記二次電池を充電するソーラー発電装置としての太陽電池パネルが設けられる。
【００５４】
道路側方の側道より外側の箇所には、各遮断部材１０ａ、１０ｂの動作を管理する制御装置３９が設けられており、指令室にある押しボタンスイッチ、キースイッチ若しくはコンピュータ等により各遮断部材の動作を遠隔操作する管制センターと前記制御装置３９との間の信号の伝達は、中継基地を介し無線信号を伝送するものでも良いが、旋回ゲート装置１１の誤動作を未然に防止するためには有線による信号伝達方式が好ましく、この場合には光ファイバ網を有する既存の道路交通情報通信システム（Vehicle Information and Communication System）を利用することが便利である。
尚、前記無線信号による遠隔操作の場合には、制御装置３９に無線用送受信器を備えることは言うまでもない。
また、制御装置３９には当該開所１に急行した警察官等の操作員が現場操作で指令を与えるための配電盤４１が設けられており、前記操作員は、「遠隔操作」／「現場操作」切替えスイッチを「現場操作」に切替えるとともに、目視で現場の状態を確認しながら、各遮断部材毎に設けた「オープン」／「ストップ」／「クローズ」の３点押しボタンスイッチ４１ａを操作し、各遮断部材の開閉動作を自在に操作することができる。
【００５５】
本実施形態の旋回ゲート装置１１は、上述したように各遮断部材の荷重や旋回による横力が前記支柱７に作用しないので、支柱本体や該本体を開所路面に固定する基礎材は、軽量且つ小型のものが採用でき、さらに各遮断部材は上記の如く先端部２６に設けた駆動輪２７、２８により駆動されるので、開所及び車道にレールや案内ガイド等の旋回案内部を設ける必要もなく、極めて短期間で且つ低コストに設置工事を終了することが可能である。即ち、旋回ゲート装置１１の設置手順は、先ず中央分離帯の適所に開所１を設け、その略中央部に支柱７を立設するとともに道路側方から該支柱７へ電力及び制御信号を供給する各種配線４２を埋設した後、前記開所１の路面に車道に対して段差の無い平坦な舗装を施す。そして、前記支柱７に各遮断部材の支持部４３を嵌合させ、各種配線を接続することで設置が完了するのである。
【００５６】
以上の旋回ゲート装置１１を用いた車輌誘導方法にあっては、通常時に各遮断部材１０ａ、１０ｂが上記スライド部材を介し開所１の路面に一体化され、道路と平行な姿勢で前記開所１を閉鎖する強固な中央分離帯を構成し、交通規制の際には、管理センターによる遠隔操作に基づき、前記制御装置３９を介して上り車道専用の遮断部材１０ａと下り車道専用の遮断部材１０ｂがそれぞれ駆動制御される。即ち、前記支柱７に対して規制区域の方向に位置する上り側遮断部材１０ａが、前記規制区域に向かって上り側の車道に旋回して当該上り側車道の車輌進行を阻止する位置まで駆動され、以後、他方の下り側遮断部材１０ｂが、下り側車道に旋回して通行部位６を開放するとともに当該下り側車道の車輌進行を阻止する位置と、逆方向に旋回して通行部位を閉鎖するとともに前記下り側車道の進行阻止状態を解除する通常位置との間を二位置的に駆動されるのである。
尚、安全性向上のため、前記各遮断部材１０ａ、１０ｂの旋回動作は、通常位置から突出完了位置までの所要時間を約５０〜９０秒、好ましくは６０〜９０秒に設定された緩慢な動作であり、更に各遮断部材の上部に設けた警告灯３８は、前記各遮断部材が通常位置から旋回動作を行う直前、好ましくは１０秒前に点滅を開始し、当該遮断部材が再び通常位置に戻るまで点滅を継続する。
【００５７】
また、上記交通規制の際には、道路適所に設置された電光掲示板４５やビーコン局４４において非常事態発生の旨、一般車輌通行禁止の旨、最寄りの出口から退出すべき旨、及び当該道路が緊急車輌専用道路に指定された旨の内容が、表示若しくはナビゲーション装置に対して無線送信され、特に誘導が行われる開所１の周辺においては、少なくとも当該開所直前の停止ライン４６付近と開所手前の数ｋｍ地点に電光掲示板４５が設けられており、以下に示すような表示が為される。
【００５８】
例えば、上り側車道における開所の２ｋｍ手前の地点に設置する電光掲示板においては、開所にて上り側車道を通行止めする２分程前から上り側遮断部材の旋回突出を予告するため図１２に示す表示がなされ、同じく上り側車道における開所直前の停止ライン４６付近に設置される電光掲示板においては、(1)上り側遮断部材の旋回突出に応じて図１３（ａ）、（ｂ）に示す表示が交互に為され、(2)下り側遮断部材による通行部位の開放に応じて図１３（ｃ）、（ｄ）に示す表示が為され、更に(3)下り側遮断部材による通行部位の閉鎖に応じて図１３（ｅ）に示す表示が為される。
また、下り側車道における開所の手前２ｋｍの地点に設置する電光掲示板においては、前記開所にて下り側車道の通行を阻止する２分程前から下り側遮断部材の旋回突出を予告するため図１４に示す表示が為され、同じく下り側車道における開所直前の停止ライン付近に設置される電光掲示板においては、(1)下り側遮断部材の旋回突出に応じて図１５（ａ）、（ｂ）に示す表示が交互に為され、(2)下り側遮断部材の逆旋回に基づく通行阻止解除に応じて図１５（ｃ）に示す表示が為される。
尚、上記図１２〜図１５に示した電光掲示板４５の設置個所、表示内容および表示のタイミングはあくまで一例を示したものであり、状況に応じて他の適宜な態様を採用することも何ら差し支えない。
【００５９】
また、各遮断部材１０ａ、１０ｂの表面には、誘導に関する案内情報や待機時間等を文字や数字、矢印等で電光表示する情報表示部を設けておくことが好ましく、例えば遮断部材１０ａの表面では、図１６（ａ）、（ｂ）に示す表示が交互に切替え表示され、遮断部材１０ｂの表面では、図１６（ｃ）、（ｄ）に示す表示が交互に切替え表示されることが好ましい。
【００６０】
さらに、開所１に対して進行方向手前側の車道に沿った適宜な位置には、図１７に示すような昇降装置１７を埋設しておき、交通規制の際には筒体２０を路面より５〜１０ｍｍ程度の僅かな高さだけ上方に突出させ、その上面を通過した車輌運転者の身体に振動を与えて非常事態を強制的に認識させることが好ましい。
その他、開所１周辺の道路状況を管制センターで監視するＣＣＤカメラを設けることや、前記停止ライン４６に停止した車輌から目視できる適宜な位置に信号機を設けることも好ましい実施例である。
【００６１】
次に、本発明の第２実施形態を図１８に基づいて説明する。
本実施形態では、通常時に開所１を閉鎖する閉止装置２として、上記第１実施形態と同様の旋回ゲート装置１１に併設され、前記開所１を臨む中央分離帯５の両端部４８、４９からそれぞれ前記開所空間内に道路長手方向に沿って移動する２つの閉鎖部材５０ａ、５０ｂと、各閉鎖部材を独立に駆動させる駆動手段５１と、この駆動手段に電力を供給する給電手段５２とを備えた開閉ゲート装置４７が設けられる。
さらに、車道に突出旋回した前記旋回ゲート装置１１の各遮断部材における先端部２６と車道側方との間には、それぞれ緊急車輌が充分に通過可能な通行空間が確保され、各空間内には、一般車輌の通行を阻止する規制装置５４として、図１７に示す昇降装置１７が埋設される。
【００６２】
前記開閉ゲート装置４７の各閉鎖部材５０ａ、５０ｂは、上記旋回ゲート装置１１の遮断部材と同様、鋼管トラス構造の本体フレームを有し、該本体フレームの長手方向に沿った適宜な複数箇所には、同様の姿勢保持手段及び当該閉鎖部材を長手方向に直線駆動する駆動手段５１が設けられる。そして、通常時には堅牢な中央分離帯を構成するとともに、交通規制の際には、２つの駆動輪及び２つの遊動輪によりその全荷重を支持された状態で中央分離帯端部に収納され、開所における通行部位の幅を拡大する。
【００６３】
前記昇降装置１７は、緊急車輌から発信される無線信号を受信する受信装置を備えており、上昇位置にある筒体２０が前記緊急車輌からの無線信号に基づき一時的に下降されることで、前記通行空間における緊急車輌の通過が可能となる。
【００６４】
これら旋回ゲート装置１１、開閉ゲート装置４７、及び昇降装置１７は、それぞれ道路側方に設けた制御装置３９により集中管理されており、外部電力が遮断された場合には、前記制御装置３９内に設けたバックアップ電源としての二次電池からそれぞれの駆動手段に電力が供給される。
その他の構成は第１実施形態と同様であり、同一構成のものには同一の符号を付し、その説明は省略する。
【００６５】
そして、本実施形態に示す各装置１１、４７、１７を用いた車輌誘導方法にあっては、通常時に各遮断部材１０ａ、１０ｂと閉鎖部材５０ａ、５０ｂが上記スライド部材を介し開所１の路面に一体化され、道路と平行な姿勢で開所１を閉鎖する強固な中央分離帯を構成し、交通規制の際には、管理センターによる遠隔操作に基づき、前記制御装置３９を介して遮断部材、閉鎖部材及び筒体がそれぞれ駆動制御される。即ち、上り側遮断部材１０ａが上り側の車道に旋回して車輌進行を阻止する位置まで駆動されるとともに上り側車道に設けた筒体２０が上昇位置に駆動され、以後、旋回ゲート装置１１及び開閉ゲート装置４７は、下り側遮断部材１０ｂを下り側車道に旋回し且つ閉鎖部材５０ｂを中央分離帯端部に重装することで、通行部位６を開放するとともに下り側車道の車輌進行を阻止する位置と、前記下り側遮断部材１０ｂを逆方向に旋回し且つ前記閉鎖部材５０ｂを前記下り側遮断部材の先端部付近まで突設し、通行部位６を閉鎖するとともに前記下り側車道の進行阻止状態を解除する通常位置との間を、二位置的に駆動されるのである。尚、前記上り側車道で上昇している筒体２０は、上記の如く緊急車輌から発信される無線信号を受けて一時下降され、当該緊急車輌の規制区域への進行を可能とする。
【００６６】
【発明の効果】
本発明に係る旋回ゲート装置によれば、遮断部材の先端部に駆動手段を設けたので、テコの原理に基づく僅かな動力により当該遮断部材を確実に旋回させることができ、且つ、旋回中心軸には強力なヒンジ構造が不要となり、単に遮断部材を回転可能に支持する簡単な構造を採用できる。
また、遮断部材は先端部に設けた駆動輪により駆動されるので、レールや案内ガイド等の旋回案内部を設ける必要もなく、極めて短期間且つ低コストで設置できる。
さらに、遮断部材の長手方向途中部に、前記先端部の駆動輪と共に該遮断部材の全荷重を支持する遊動輪を設け、これら駆動輪及び遊動輪により前記遮断部材が自立して旋回走行することとしたので、遮断部材の端部を回転可能に支持している旋回中心軸には、当該遮断部材を旋回させるための駆動手段は勿論のこと、遮断部材の荷重が作用しないため該遮断部材の荷重を支持する支持強度も不要であり小さなものが採用でき、また、これを固定する基礎材も、軽量且つ小型のものが採用でき、基礎工事や据付工事が簡単になる。
さらにまた、前記旋回中心軸の強度にかかわらず、長い遮断部材や上述の鋼管溶接構造の本体フレームからなる遮断部材も採用できる。
【００６７】
遮断部材は、断面視三角形の各頂点位置にそれぞれ配された長手方向に延びる主鋼管と、これら主鋼管をトラス状に連結するトラス管とより構成される鋼管溶接構造の本体フレームからなるので、該遮断部材が軽量且つ堅牢な構造となり重心が低く、車輌の衝突や人為的な破壊行為、いたずら行為等にも充分に耐え得るとともに、風圧を逃がすことが可能となり、台風等の強風にも充分耐え得る構造にすることができる。
【００６８】
本体フレームの表面には、亜鉛メッキ仕上げのうえ粉体塗装を施したので、排気ガスその他の汚れが脱落容易に処理される。
【００６９】
駆動輪は、耐磨耗性及び耐暑耐寒性に優れたウレタン系のソリッドゴムタイヤからなるので、天候に左右されず路面上を常時静寂且つ滑らかに転動する。
【００７０】
駆動輪の設置角度は、車輪の軸方向が旋回中心軸を通る旋回半径の方向に一致するように設定されており、遮断部材の旋回動作に基づいて旋回中心軸に過大な横力が作用するといったことも回避されている。
【００７１】
駆動手段は、手動により遮断部材を旋回させる手動旋回機構を備え、具体的には、歯車減速機の出力軸先端に、手動旋回機構としてクラッチ及び該クラッチの動力伝達を遮断するためのクラッチレバーを設け、前記クラッチレバーを操作することで人力による旋回動作を可能としたので、万一、駆動手段や電力供給手段等に不具合が生じた場合も、前記クラッチレバーを操作して動力伝達を遮断させることで、遮断部材が人力により旋回動作可能となり、混乱を生じることなく前記遮断部材を柔軟且つ確実に旋回させることができる。
【００７２】
給電手段がバックアップ電源として二次電池を備え、且つ駆動手段の駆動モータが直流モータであるので、主電源が遮断されても、旋回ゲート装置を相当回数作動させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a vehicle guidance technique on a road having a median such as a highway or a highway. More specifically, the present invention relates to a vehicle that travels on the road safely and promptly in traffic regulation based on a disaster or an accident. The present invention relates to a vehicle guidance method for guiding to an oncoming road, a turning gate device, and an opening / closing gate device.
[0002]
[Prior art]
When an emergency such as a disaster or accident occurs, vehicles traveling on highways and main roads as well as ordinary roads are inevitably involved in heavy traffic. Many of the main roads and expressways are designated as emergency vehicle-only roads in the event of an emergency. If an emergency occurs as described above, police officers or other guidance personnel will be required at each entrance to the road. Vehicles are closed, toll gates are closed, etc., and general vehicles are completely blocked.
However, the main roads and expressways are usually provided with a median strip to which a protective body is secured to prevent the traveling vehicle from deviating or moving to the oncoming road side, so that it is suitable for, for example, disaster areas or accident sites. Each vehicle that has already stagnated on the upstream side road cannot make a U-turn by bypassing the downstream side road, and the traffic paralysis state of the road continues for a long time.
In such a state of traffic paralysis, emergency vehicles such as emergency fire fighting and fire fighting support vehicles, emergency rescue vehicles, food and support supplies transport vehicles, accident handling vehicles from neighboring prefectures in the vicinity are brought to the disaster area or accident site. It was impossible to rush, and this delay in relief work contributed to the expansion of the damage.
[0003]
On the other hand, Japanese Patent Laid-Open No. 4-213606 discloses removable barriers 502 and 502 provided in the middle of a road median strip 500 as shown in FIG. 19, and in the event of a traffic accident or traffic jam. In addition, it is disclosed that the barrier is moved in parallel with the road to form a passage 501 through which a vehicle traveling on one road 503a can exit to the oncoming road 503b. In this way, if a passage is formed in the central separation zone and the stagnating vehicle is detoured to the oncoming road via the passage 501, the paralysis state of the traffic can be gradually eliminated.
[0004]
[Problems to be solved by the invention]
However, in order to safely and smoothly merge the vehicle on the upstream roadway with the traffic on the downstream roadway through the passage 501, a large number of guidance personnel, guidance equipment, guidance vehicles, and these personnel and equipment are transported. Human and physical elements such as vehicles are required in the passage and its surroundings, and it is practically difficult to start these guidance before traffic congestion occurs after an accident or disaster occurs. Guidance on roads and highways is very dangerous. And the upside road will continue to be confused until the guidance is effectively made, and the purpose of quickly eliminating the paralysis state of the road and converting the road to an emergency vehicle road in a short time There were limits to achieve.
[0005]
The present invention has been made in view of the present situation, and when a disaster or accident occurs, it is an upward roadway toward a restricted area such as the disaster area or accident site on a main road or highway having a median. By guiding the vehicle traveling on the road safely and promptly to the downside roadway, we will provide a vehicle guidance technology that allows the general vehicle to be quickly discharged from the road and quickly converted into an emergency vehicle road. .
[0006]
[Means for Solving the Problems]
In other words, the present invention provides an upright turning center axis, a blocking member that turns with the end supported by the turning center axis, and a tip of the blocking member in the turning radius direction.Provided,Driving wheels that roll on the road surfaceAnd an idler wheel that is provided in the middle of the blocking member in the longitudinal direction and supports the entire load of the blocking member together with the driving wheel, and drives the driving wheel.The driving means and power supply means for supplying power to the driving means,The blocking member is self-supporting and turns around the turning center axis, and the blocking member isThe position to prevent the vehicle from movingThe vehicleTwo-position swivel to the normal position to cancel the progress prevention stateDo itA swivel gate device is provided.
[0007]
In particular, a position in which the turning center shaft is erected adjacent to the roadway and the turning member that turns while the end of the turning center shaft is supported by the turning center shaft turns on the roadway to prevent the vehicle from moving forward. And a turning gate device that is turned in two directions between the normal position that turns in the opposite direction and is parallel to the roadway and releases the passage blocking state.
[0008]
Further, an upright turning center axis, two blocking members rotating with the end supported by the turning center axis, and a distal end portion of each blocking member in the turning radius directionRoll on the road surface providedDriving wheelAnd an idler wheel that is provided in the middle of each blocking member in the longitudinal direction and supports the entire load of each blocking member together with the driving wheel, and drives the driving wheel.It is composed of drive means and power supply means for supplying power to the drive means, and each blocking member isEach independentlyStand on its ownRotating around the turning center axis, each blocking member,A position to prevent the vehicle from moving,The vehicleTwo-position swivel to the normal position to cancel the progress prevention stateDo itA swivel gate device is provided.
[0009]
These turning gate devices are provided with a driving means at the tip of the blocking member, so that the blocking member can be reliably turned by a slight power based on the lever principle, and the turning center shaft is powerful. A hinge structure becomes unnecessary, and a simple structure that simply supports the blocking member in a rotatable manner can be adopted. Further, since the blocking member is driven by the driving wheel provided at the tip, it is not necessary to provide a turning guide such as a rail or a guide guide, and it can be installed in a very short period of time and at a low cost.Further, an idler wheel that supports the full load of the blocking member is provided in the middle of the blocking member in the longitudinal direction together with the driving wheel at the distal end, and the blocking member independently turns by the driving wheel and the idler wheel so as to turn. The turning center shaft that rotatably supports the end of the blocking member supports the load of the blocking member because the blocking member does not act as well as the drive means for rotating the blocking member. Supporting strength is not required and a small one can be adopted. Also, a base material for fixing the same can be light and small, and the foundation work and installation work can be simplified. Further, regardless of the strength of the pivot center axis, a long blocking member or a blocking member composed of the main body frame of the above-described steel pipe welded structure can also be employed.

[0011]
It is preferable that the surface of the main body frame is galvanized and then powder-coated so that exhaust gas and other dirt can be easily removed.
[0012]
A plurality of drive wheels that are synchronously driven by a roller chain are provided at the tip of the blocking member, and these drive wheels are made of a urethane-based solid rubber tire excellent in wear resistance and heat and cold resistance. It is preferable in that it rolls quietly and smoothly on the road surface regardless of the weather.
[0013]
The installation angle of the drive wheel is set so that the axial direction of the wheel coincides with the direction of the turning radius passing through the turning center axis, and an excessive lateral force acts on the turning center axis based on the turning operation of the blocking member. This is also avoided.
[0014]
The front end of the blocking member is provided with a drive motor and a gear reducer that transmit a driving force to the driving wheel as the driving unit, and the driving unit includes a manual turning mechanism for manually turning the blocking member. It is preferable to provide.
[0015]
Specifically, a clutch and a clutch lever for interrupting the power transmission of the clutch are provided at the tip of the output shaft of the gear reducer as a manual turning mechanism, and the turning operation can be performed manually by operating the clutch lever. This is the preferred embodiment. As a result, even if a malfunction occurs in the drive means, power supply means, etc., by operating the clutch lever to shut off power transmission, the shut-off member can be turned by human power without causing confusion. The blocking member can be turned flexibly and reliably.
[0016]
Further, if the power supply means includes a secondary battery as a backup power source and the drive motor of the drive means is a DC motor, the turning gate device can be operated a considerable number of times even when the main power supply is shut off.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail with reference to the accompanying drawings.
[0018]
1 to 5 are conceptual diagrams showing the technical idea of the present invention. In the figure, reference numeral 101 denotes an opening for allowing the vehicle to pass to the opposite roadway side at an appropriate position on the central separation zone 100 of the road, and 102 denotes a closing device for closing the opening so as to be opened and closed by a driving means.
[0019]
FIG. 1 is a conceptual diagram illustrating a vehicle guidance method according to the present invention.
Normally, the opening 101 is closed by the closing device 102 so that the vehicle cannot pass as shown in FIG. The closing device 102 is provided with a driving means (not shown), such as remote control by a control center or the like for traffic control based on the occurrence of a disaster or an accident, or about 1 to 3 police officers who rushed to the site. Starting and other guiding operations are performed by on-site operation by an operator or automatic control based on signals from various detectors provided around the site. And when providing the closing device 102 or the regulating device separately in this way, the closing device 102 and the regulating device are driven to prepare the left side of the road in the figure without preparing a large number of guidance personnel or guidance tools. The vehicle 105a traveling on the upstream roadway 103 toward the restricted area indicated by the hatched area is promptly and safely guided to the downstream roadway 104, and the vehicles 105a and 105b on the road are not congested for a short time. It is discharged outside the road.
Here, the restricted area refers to an area where a disaster or an accident occurs, and refers to an area where entry of a general vehicle is restricted.
[0020]
Various guidance information and warning information related to guidance such as disaster or accident situation and regulation area, the exact position of the opening 101, guidance method, etc. are appropriate for the opening 101 along the roadways 103 and 104 on the front side in the traveling direction. By an electronic bulletin board that displays the character information in the position and electronically, and a beacon station that is also provided at an appropriate position and transmits map information, simplified map information, character information, voice information, etc. via the in-vehicle navigation device, It is recognized by the driver of the vehicles 105a and 105b. Here, if bad weather such as fog, morning and evening time zones, road shape, structure, etc., the situation of the electric bulletin board and the opening 101 is poor, or the driver's concentration is reduced, etc. An elevating device 17 to be described later for embedding a single or a plurality of cylinders whose upper ends are closed with respect to the road surface is embedded in an appropriate position on the front side of the opening 101, and when the traffic is restricted, the cylinder is slightly placed from the road surface. It is preferable to force an emergency to be recognized by projecting upward and applying vibration to the vehicle driver's body that has passed through the upper surface.
[0021]
Next, a procedure for guiding the vehicle 105 a traveling on the upside roadway to the downside roadway 104 using the closing device 102 will be described. At the time of traffic regulation, first, as shown in FIG. 1 (b), at the position 107 where the passage portion 106 having at least one vehicle width of the opening 101 on the upstream side road 103 is on the front side in the traveling direction, the upstream side The vehicle 105a on the roadway 103 is prevented from traveling and closed. Thereafter, the following first induction process and second induction process are alternately repeated.
[0022]
That is, as shown in FIG. 1 (c), at least the advancing portion 106 in the opening 101 is opened, and the vehicle 105a that has been prevented from advancing on the ascending roadway 103 passes through the passage portion 106 as indicated by a chain line arrow in the figure. And a first guidance process for preventing the vehicle 105b on the downward road 104 from traveling at an appropriate position 108 on the downstream side 104 in the forward direction of travel in the downward road 104, and FIG. As shown in FIG. 1 (d), at least the passage portion in the opening 101 is closed to block the passage of the vehicle 105a to the downside road 104 and to release the state of blocking the passage of the vehicle 105b in the downside road 104. The second induction process is repeated alternately.
[0023]
In the present invention, the vehicles 105a and 105b on the upside road 103 and the downside road 104 are alternately guided in this way, so that the vehicle 105a guided on the downside road 104 contacts the vehicle 105b traveling on the roadway. Or, an accident such as a collision can be prevented in advance, and safety during guidance can be maintained. Here, if the vehicle detection means or the speed detection means is installed at an appropriate position on the front side in the traveling direction with respect to the opening 101 in each of the ascending roadway 103 and the descending roadway 104, the closing device 102 is installed in the control center. When the road condition is confirmed during remote operation, the safety of the vehicle can be improved. Further, if the driving of the closing device 102 is controlled based on the road condition obtained by the vehicle detection means and the speed detection means, the above 2 Two induction processes can be performed more efficiently.
[0024]
As the closing device 102, various forms of devices such as a lifting device, an opening / closing gate device, a blocking device having a lifting and lowering fence, and a chain gate device, which will be described later, can be adopted. Alternatively, it includes a plurality of blocking members that rotate about an original turning center axis and turn and project to the upside road 103 or the downside road 104, and the opening of the opening 101 and the roadway 103 or It is preferable to use a swing gate device capable of simultaneously preventing the vehicle from moving in 104 alone or in combination with another device.
[0025]
For example, FIG. 2 shows a conceptual diagram of a vehicle guidance method using the turning gate device 111A. The turning gate device 111A includes a turning center shaft 109 that is erected substantially at the center of the opening 101, and two blocking members 110a and 110b that turn with the ends supported by the turning center shaft 109, A driving means (not shown) that independently drives each blocking member to turn and a power feeding means (not shown) that supplies electric power to the driving means are provided. Normally, as shown in FIG. 2 (a), the two members 110a and 110b are connected to a road. The opening 101 is closed by being arranged in a straight line parallel to.
[0026]
Here, the turning center axis includes those that simply support the rotation of the blocking member without rotating themselves, and those that function as a transmission shaft that rotates integrally with the blocking member and transmits torque, Those that support the load of the blocking member and those that do not support are included.
[0027]
Further, the two blocking members share one turning center axis provided substantially at the center of the opening, and each of the two blocking members turns independently with the end supported by the turning center axis, This includes one that turns independently with two end portions supported by two unique turning center axes arranged in parallel in the substantially central portion.
[0028]
When the traffic is restricted, the turning gate device 111A, first, as shown in FIG. 2 (b), the upward blocking member 110a positioned in the upward traveling direction with respect to the turning central shaft 109 is indicated by a chain line arrow in the figure. In this manner, the vehicle is driven to turn to prevent the vehicle 105a from projecting on the upstream side road 103, and thereafter, as shown in FIG. 2 (c), the other downstream side blocking member 110b is driven to turn as indicated by a chain line arrow. The first guiding process for opening the passage portion 106 and preventing the vehicle 105b from traveling on the descending roadway 104, and as shown in FIG. 2 (d), the descending blocking member 110b is turned in the reverse direction to the normal position. Thus, the second guiding process for closing the passage portion and canceling the travel-blocking state of the descending roadway 104 is repeated alternately.
According to such a vehicle guidance method using the turning gate device 111A, when each of the blocking members 110a and 110b turns and protrudes on the roadway, the member positioned on the far side in the vehicle traveling direction with respect to the turning center shaft 109 Since the vehicle enters the road while maintaining an obtuse angle with respect to the traveling vehicle approaching the direction, it is easy for the driver of the vehicle to see, and even if it collides with the member, the vehicle collides with the side of the member. Therefore, there is no danger of jumping to the oncoming road and causing a catastrophe. In addition, it is preferable to provide an information display unit that electrically displays guidance information related to guidance with characters, arrows, etc. on the surface of each blocking member 110a, 110b. For example, the surface of one blocking member 110a stops for a while. It is preferable to switch and display that it should pass and pass through the passage, and on the surface of the other blocking member 110b, it is switched and displayed that it should stop for a while and should go straight.
[0029]
In addition, the swing gate device 111B shown in FIG. 3 having the same meaning is provided with two pieces standing adjacent to the roadways 103 and 104 at the end portions 112 and 113 of the central separation band 100 facing the opening 101, respectively. Rotation center shafts 109c, 109d and 109e, 109f, four blocking members 110c, 110d, 110e, 110f that rotate with their ends supported by the respective rotation center shafts, and each blocking member are driven to rotate independently. A drive means (not shown) and a power supply means (not shown) for supplying electric power to the drive means are provided. Normally, as shown in FIG. 3 (a), the ascending road surface 103 is located on the upstream side in the traveling direction. The first line member 110c, the second upward line member 110d that is also located on the far side in the traveling direction, and the downstream line that faces the descending roadway 104 and is located on the front side in the traveling direction. A first member 110e, closes the said Opened 101 four blocking members made of a downline second member 110f positioned in the traveling direction of the rear side also by causing parallel to the road, respectively.
[0030]
As shown in FIG. 3B, a preferable operation procedure at the time of traffic regulation by the turning gate device 111B is to first drive the up-line first member 110c to prevent the vehicle 105a from projecting on the up-side road 103. Similarly, as shown in FIG. 3 (c), the up-line second member 110d is driven to turn on the up-side roadway 103. Thereafter, as shown in FIG. FIG. 2 (d) shows a first guiding process for canceling the progress blocking state and driving the down line first member 110e to turn to open the passage portion 106 and prevent the vehicle 105b from traveling on the down side roadway 104. As shown, the up line first member 110c is driven to turn to prevent the vehicle from traveling on the up side road 103, and the down side first member 110e is moved to the normal position. In the opposite direction being rotated driven, it is preferable to repeat with closing the passage portions 106 alternating with a second inductive step of releasing the progress blocking state of the downlink side roadway 104.
[0031]
As in the case of the above-described turning gate device 111A, it is preferable to provide an information display unit that electrically displays guidance information on guidance on the surface of each blocking member. For example, the vehicle progresses by turning and projecting on the roadway. In the information display portions of the blocking members 110c and 110e that prevent the vehicle from being switched, a message indicating that the vehicle should stop for a while and to proceed is displayed, and in the information display portion of the blocking member 110d that guides the vehicle 105a to the traveling part 106, an arrow indicates The direction of the passage part 106 is preferably displayed.
In the above procedure, the turning operation of the up line first member 110c and the up line second member 110d at the start of guidance may be either a synchronous operation or a differential operation. In consideration of the above, it is preferable to first turn the up-line first member 110c that protrudes into the roadway while maintaining an obtuse angle with respect to the traveling vehicle whose tip direction approaches. Similarly, the turning operation of the up line first member 110c and the down line first member 110e at the time of the alternate induction of the two processes may be either a synchronous operation or a differential operation. In order to prevent the vehicle 105a from being sandwiched between the blocking member 110d that protrudes from the vehicle and the blocking member 110c that is turned, the member that prevents the vehicle from moving in each process, that is, in the first guiding process. In the second guiding process, it is preferable that the descending first member 110e and the ascending first member 110c be pivoted first.
Further, in the above series of guiding operations, the advancement prevention or inhibition release of the vehicle 105a on the upside road 103 is repeatedly performed by the reciprocating turning operation of the upline first member 110c. For example, the upline first member 110c is When the upward second member 110d completes the turning projection, it is turned backward and returned to the normal position, and the subsequent two-stage alternate guidance is performed by the turning operation of the downward first member 110e, so that power consumption can be saved. preferable.
[0032]
In the above-described turning gate device 111B, high safety can be maintained as in the case of the turning gate device 111A including the two blocking members 110a and 110b, and the turning gate device 111A has a blocking member longer than necessary. Even when it is provided in a wide central separation band that is necessary, it is possible to use an appropriate blocking member according to the width of the roadway.
[0033]
By the way, the turning gate devices 111A and 111B used in each of the vehicle guiding methods described above are configured so that the blocking member protrudes in a direction substantially perpendicular to the roadway to prevent the vehicle from traveling on the roadway. Is appropriately set to a dimension corresponding to the width of the roadway. Therefore, when the opening is closed by using the turning gate device 111A or 111B alone as shown in FIG. 2 or FIG. The width of the passage portion 106 is about one lane, and this width may not be large enough for large vehicles such as buses and trucks to pass quickly and smoothly.
[0034]
In such a case, as shown in FIG. 4, as the closing device 102 for closing the opening 101, the swing gate device 111 </ b> A and an open / close gate device 116 that is separately configured are provided, and the width of the passage portion 106 is blocked by a blocking member. It is preferable to be able to expand beyond this length. That is, the closing device 102 includes two closing members 114 and 115 that move along the longitudinal direction of the road into the space of the opening 101 from both ends 112 and 113 of the central separation zone facing the opening 101, respectively. An opening / closing gate device 116 provided with a drive means (not shown) that is driven independently and a power supply means (not shown) that supplies power to the drive means is provided side by side with the turning gate device 111A. ), The two blocking members 110a and 110b of the turning gate device 111A are arranged in a straight line parallel to the road, and the two closing members 114 and 115 of the opening and closing gate device 116 are arranged from both ends of the central separation band. By projecting into the open space 101, the open space 101 is closed so that the vehicle cannot pass. The procedure of the guiding operation of the turning gate device 111A is the same as that described above. However, as shown in FIG. 4B, the open / close gate device 116 is interlocked with the downward blocking member 110b of the turning gate device 111A. The closing member 115 located in the downward traveling direction moves in the downward traveling direction and is overlapped with the central separation band 100 outside the open space, thereby expanding the opening width of the passage portion 106.
[0035]
If the opening / closing gate device 116 can be driven independently of the turning gate device 111A, only the opening / closing gate device 116 is operated so as not to hinder the traveling of a general vehicle on the roadway. Only emergency vehicles and construction vehicles can pass through the opening.
[0036]
Here, the closing device 102 shown in FIGS. 2 to 4 is configured symmetrically along the longitudinal direction of the road so that it can easily cope with the opening regardless of which direction is the restricted area. When the direction of the regulated area to be actuated is determined in one direction in advance, for example, when the opening is provided in preparation for an accident or collapse in the tunnel, or when the down roadway is provided immediately before the road exit Alternatively, the following asymmetric configuration may be used.
[0037]
That is, FIG. 5A shows a conceptual diagram of an asymmetric turning gate device 111C provided in preparation for an accident or collapse in the tunnel indicated by the hatched area on the left side of the drawing. A turning center shaft 109g erected at the tunnel side end 112 of the median strip 100 facing the opening 101, and one blocking member 110g swirled with the end supported by the turning center shaft 109g; A driving means (not shown) for turning the blocking member and a power supply means (not shown) for supplying electric power to the driving means are provided. The blocking member 110g advances the opening 101 in the upstream roadway 103 toward the tunnel. The vehicle is swiveled in conjunction with the lifting / lowering operation of the lifting / lowering device 117 that prevents the vehicle 105a from advancing at a position 107 on the front side in the direction.
[0038]
As an embodiment of the lifting device 117, a vehicle traffic restriction device described in Japanese Patent Publication No. 2861952, that is, the lifting device 17 shown in FIG. That is, the elevating device 17 is a raised position where the main body portion 18 is buried in the ground of the roadway and the vehicle travel path width is substantially narrowed at a position protruding above the upper plate 19 constituting the road surface to prevent vehicle travel. And a single or a plurality of cylinders 20 closed at the upper end that move up and down two-way between the lowering position that does not prevent the vehicle from moving at a position lowered near the road surface, and driving means for driving the cylindrical body 20 to move up and down And a feeding means for supplying power to the driving means, and the cylinder 20 directly acts as a regulating member 120 that regulates the traveling of the vehicle 105a.
[0039]
Then, the operation of the turning gate device 111C and the lifting device 117 at the time of traffic regulation is performed by first moving the regulating member 120,... Of the lifting device 117 to the raised position to prevent the vehicle from traveling on the upstream side road 103, and then turning. A first guiding process for turning the blocking member 110g of the gate device 111C to the downward side roadway 104 to open the passage portion 106 and preventing the vehicle from traveling on the downward side roadway 104, and reverse the blocking member 110g to the normal position. The second guiding process of alternately turning in the direction to close the passage portion 106 and canceling the travel-preventing state of the descending roadway 104 is alternately performed. Here, if an opening / closing gate device having one closing member is provided on the front end side of the blocking member 110g, the passage area 106 can be further enlarged.
[0040]
In addition, as shown in FIG. 5 (b) for the same purpose, it is provided at the opening 101 in preparation for an accident or collapse in the tunnel indicated by the hatched area on the left side of the figure, and the swing gate device 111A and the device are lowered. If the asymmetric opening / closing device 102 including the opening / closing gate device 116 </ b> C having the closing member 115 only in the lateral direction is configured, the passage part 106 can be enlarged by the movement of the closing member 115.
[0041]
The vehicle guiding method of the present invention is not limited by the number of lanes on the road, and in the case of a wide road having three or more lanes on one side, this can be achieved by setting the blocking member of the turning gate device to be long. It is also possible to supplement the vehicle advance prevention function by the blocking member by installing a regulating device separately configured on the side of the road. Such a regulating device does not require a particularly high impact strength as that of each of the above-mentioned swivel gate devices that are normally used as a protection body for the median strip. In addition to the lifting device 17 shown in FIG. A swivel gate device, an open / close gate device, a shut-off device, a chain gate device, and other devices having a vehicle progress inhibiting function, which include a drive unit and a power feeding unit, can be suitably employed.
[0042]
Even when a general vehicle is being guided, it is preferable to secure a traffic space in which the emergency vehicle can travel on the side of the road including the road shoulder on the upside. For example, the length of each blocking member of the turning gate device Is set to a size that allows the passage space to be formed between the front end and the road side end, or when a regulating device such as the lifting device is provided on the side of the road, Preferably, the restriction device is temporarily opened based on a wireless signal. Also, in order for the emergency vehicle to travel more smoothly on the side of the road, the above-mentioned electric bulletin board or beacon station provided on the upstream roadway will stop the vehicle by bringing the vehicle to the right in the direction of travel relative to the general vehicle. It is desirable to display or wirelessly transmit guidance information.
[0043]
In the present invention, by adopting the vehicle guidance method as described above, it is possible to guide the vehicle safely and promptly by an unmanned or small number of operators, which could not be done by the barrier 502 shown in FIG. The road will be converted into an emergency vehicle-only road in a short time, so emergency vehicles heading to the restricted area will not be involved in traffic jams on the road, and will be able to carry out quick relief activities in disaster areas and accident sites It becomes. In addition, if the above-mentioned symmetric or asymmetric turning gate devices and opening / closing gate devices employed in the vehicle guidance method of the present invention are provided at the end of the central separation band facing the intersection of the main road, the vehicle enters the intersection. The vehicle can be guided to the opposite road to reverse the road, or vehicles entering the road from the intersection can be reliably blocked, and traffic can be controlled according to disasters, accidents and other road conditions Easy to do.
[0044]
Moreover, the case where the turning gate device and the open / close gate device share the power feeding means is included.
[0045]
Next, the present invention will be described in more detail based on the drawings showing specific embodiments for realizing the vehicle guidance method described above. FIGS. 6 to 17 show a first embodiment of the present invention, FIG. 18 shows a second embodiment, 5 in the figure shows a median strip, and 11 shows a swivel gate device.
[0046]
First, a first embodiment of the present invention will be described. FIG. 6 is an explanatory view showing the turning gate device 11 provided on the highway.
[0047]

【The invention's effect】
According to the turning gate device of the present invention, since the driving means is provided at the tip of the blocking member, the blocking member can be reliably turned by a slight power based on the lever principle, and the turning center axis In this case, a strong hinge structure is not required, and a simple structure that simply supports the blocking member in a rotatable manner can be adopted.
Further, since the blocking member is driven by driving wheels provided at the tip, it is not necessary to provide a turning guide such as a rail or a guide guide, and can be installed in a very short period of time and at a low cost.
Furthermore, an idler wheel that supports the full load of the blocking member is provided in the middle of the blocking member in the longitudinal direction together with the driving wheel at the distal end, and the blocking member independently turns by the driving wheel and the idler wheel. Therefore, since the turning center shaft that rotatably supports the end of the blocking member is not driven by the driving member for rotating the blocking member, the load of the blocking member does not act. The supporting strength for supporting the load is not required and a small one can be adopted. Also, the base material for fixing the load can be a lightweight and small one, and the foundation work and the installation work are simplified.
Furthermore, regardless of the strength of the pivot center axis, a long blocking member or a blocking member composed of the main body frame of the above-described steel pipe welded structure can be employed.
[0067]
Since the blocking member is composed of a main frame of a steel pipe welded structure composed of a main steel pipe extending in the longitudinal direction arranged at each vertex position of the triangle in cross-sectional view, and a truss pipe connecting these main steel pipes in a truss shape, The blocking member has a lightweight and robust structure, has a low center of gravity, can sufficiently withstand vehicle collisions, artificial destruction, and mischief, and can also release wind pressure, enough for strong winds such as typhoons A structure that can be withstood can be obtained.
[0068]
Since the surface of the main body frame is galvanized and powder-coated, exhaust gas and other contaminants are easily removed.
[0069]
The drive wheels are made of urethane solid rubber tires that are excellent in wear resistance and heat and cold resistance, so that they are always quietly and smoothly rolling on the road surface regardless of the weather.
[0070]
The installation angle of the drive wheel is set so that the axial direction of the wheel coincides with the direction of the turning radius passing through the turning center axis, and an excessive lateral force acts on the turning center axis based on the turning operation of the blocking member. This is also avoided.
[0071]
The driving means includes a manual turning mechanism for manually turning the blocking member. Specifically, a clutch and a clutch lever for cutting off power transmission of the clutch as a manual turning mechanism are provided at the distal end of the output shaft of the gear reducer. Because it is possible to turn by human power by operating the clutch lever, even if a failure occurs in the drive means, power supply means, etc., the clutch lever is operated to cut off power transmission Thus, the blocking member can be turned by human power, and the blocking member can be turned flexibly and reliably without causing confusion.
[0072]
Since the power supply means includes a secondary battery as a backup power source and the drive motor of the drive means is a DC motor, the turning gate device can be operated a considerable number of times even when the main power supply is shut off.
