【産業上の利用分野】
本発明は、ロッド着脱装置付き削孔機に関し、とくに重いロッドの取扱を機械化し且つロッド心合わせの自動化が可能なロッド着脱装置付き削孔機に関する。
【0002】
【従来の技術】
アンカーの設置、地盤強化材注入その他の目的で地表から地中へ傾斜孔を穿つ場合がある。そのための削孔機の一例を図3に示す。削孔機1は、一定長さの鋼管製のロッド7の先端に掘削ビット(図示せず)を取付け、そのロッド7を案内部4に沿って推進・回転駆動部5により回転させながら押し下げて削孔する。図示例の案内部4は、支持台2から起伏手段3によって所要の傾斜角αで支持される。駆動部5の推進は案内部4により掘削軸線16に心合せして行われる。ロッド7を、駆動部5との結合及び好ましくはクラッチ付きである軸受部6の支承により掘削軸線16と心合せする。ロッド7の長さより深い孔を掘るためには、先行のロッド7の上端が軸受部6まで下降した時に、駆動部5を先行のロッド7から分離してロッド長さ以上の距離だけ後退させ、次のロッド7を先行のロッド7に継足した後、駆動部5を次のロッド7の上端に結合させた上でこれを駆動する。ロッド7の継足しを繰返すことにより、任意の深さの孔を掘ることができる。
【0003】
図3(A)は傾斜角αが零(α=0)の時の削孔機1の平面図を示し、図3(B)は傾斜角αを約45゜とした場合の側面図を示す。ただし角度αは一定範囲内の任意の値を取り得るもので、図示例に限定されない。
【0004】
【発明が解決しようとする課題】
しかし、従来の削孔機1には次の問題点があった。
(1)ロッド7には種々のサイズがあるが、大口径で長尺のものはかなりの重量になり(外径120mm、長さ2mで約60kg)、人力による取扱が困難である。
(2)駆動部5とロッド7の心合わせのため、重いロッド7を微妙に移動させる必要があり、心合わせが面倒であり時間がかかる。
【0005】
従って、本発明の目的は、ロッドの取扱及び心合せを機械化できるロッド着脱装置付き削孔機を提供するにある。
【0006】
【課題を解決するための手段】
図1、図2、及び図3を参照するに、本発明のロッド着脱装置付き削孔機1は、ロッド7の駆動を掘削軸線16に沿って案内する上方開放の案内部4を有する削孔機1に、案内部4内の掘削軸線16上の2点に臨む位置から直角方向に水平に延びる第1ラック15及び第2ラック15、第1ラック15及び第2ラック15の下方に設けた支持台11、第1ラック15の削孔機1と近い部分及び遠い部分を支持台11に結合する前方傾斜ジャッキ12f1及び前方送受ジャッキ12f2、並びに第2ラック15の削孔機1と近い部分及び遠い部分を支持台11に結合する後方傾斜ジャッキ12r1及び後方送受ジャッキ12r2を有するロッド棚装置10を併置し、第1ラック15及び第2ラック15上に前記掘削軸線16を含む鉛直面と平行にロッド7を載置し、前方傾斜ジャッキ12f1及び前方送受ジャッキ12f2に対する後方傾斜ジャッキ12r1及び後方送受ジャッキ12r2の長さの調節により第1及び第2ラック15、15上のロッド7を掘削軸線16の傾斜に傾け、前方傾斜ジャッキ12f1及び後方傾斜ジャッキ12r1に対する前方送受ジャッキ12f2及び後方送受ジャッキ12r2の長さの調節により第1及び第2ラック15、15上のロッド7を案内部4へ転がして装着するか又は案内部4内で削孔機1との結合から解除したロッド7を手動で転がして第1及び第2ラック15、15上へ離脱させる。
【0007】
図1において掘削機1の関連部分を2点鎖線で示し、図3においてロッド棚装置10の関連部分を点線で示す。
【0008】
好ましくは、第1及び第2ラック15、15上のロッド7が載置される位置に接して上下動爪26(図4)を設け、その上下動爪26の昇降により第1及び第2ラック15、15上のロッド7の転がりを制御する。
【0009】
図1に示すロッド棚装置10の実施例は、ラック15、15からなる対の3対を上下配置で支持しているが、本発明は1対以上のラック15、15を設ければ足りこの実施例に限定されない。
【0010】
さらに好ましくは、図3及び図5に示すように削孔機1の案内部4におけるロッド4の位置の下方の所定位置に掘削軸線16と平行な案内突条9を形成し、案内突条9と嵌合可能な可動受け具8を案内部4に取付ける。受け具8の形状を、案内突条9との嵌合時にロッド7を掘削軸線16と心合せして受け止める如きものとする。ロッド7を削孔機1内へ装着する際に、受け具8を案内部4の所定位置で案内突条9に嵌合させ第1ラック15及び第2ラック15からのロッド7を可動受け具8上へ転がし込んで位置決めする。ロッド7を削孔機1から離脱する際に、受け具8を所定位置で案内突条9に嵌合させ、ロッド7を受け具8で支持したまま削孔機1との結合から解除し、解除後のロッド7を手動で転がし第1ラック15及び第2ラック15へ離脱させる。
【0011】
【作用】
本発明によれば、図1のロッド棚装置10を図3の削孔機1に併置し、図1における第1ラック15及び第2ラック15の左端、即ち削孔機1側の端部を削孔機1の上方開放構造の案内部4内の掘削軸線16に臨ませる。図示例の場合、第1ラック15及び第2ラック15をこのように配置すると、両ラック15、15が掘削軸線16と直交する向きになり、ロッド棚装置10でラック15の長さ方向に対し直角に載置したロッド7は削孔機1の掘削軸線16を含む鉛直面と平行になる。
【0012】
図2を参照するに、前方傾斜ジャッキ12f1及び前方送受ジャッキ12f2の長さに比して後方傾斜ジャッキ12r1及び後方送受ジャッキ12r2を長く、等しく又は短くして、ロッド棚装置10上のロッド7の傾斜角を削孔機1の掘削軸線16の傾斜角αに一致させる。例えば、図2の点線位置7aのようにロッド7の傾斜角αを約45゜とすることができる。
【0013】
次いで、前方傾斜ジャッキ12f1及び後方傾斜ジャッキ12r1に対する前方送受ジャッキ12f2及び後方送受ジャッキ12r2の長さの調節によりロッド棚装置10の第1ラック15及び第2ラック15(総括的にラック15と呼ぶ場合がある。)の水平に対する傾き角βを図4に示すように調節することができる。例えば、前方傾斜ジャッキ12f1及び後方傾斜ジャッキ12r1の長さに比して前方送受ジャッキ12f2及び後方送受ジャッキ12r2を長くし、ラック15を削孔機1の掘削軸線16に向けて下降する向きに傾け(β>0゜、例えば+5゜)、図1(B)のラック15上で掘削軸線16に最も近いロッド7を重力によりラック15上で転がして削孔機1の案内部4内の受入れ空間40に装着することができる。受入れ空間40は、ロッド7がない時の案内部4の内部空間である。よって、ロッド7の装着を機械化できる。さらに、上記受け具8を削孔機1の案内部4に配置しておけば、ラック15からの装着と同時にロッド7を掘削軸線16と心合せすることができる。この場合には、ロッド7の心合せの機械化が可能になる。
【0014】
こうして装着したロッド7を、駆動部5の回転又は他の手段により、先行ロッド7及び駆動部5に結合してロッド継足しを完了する。受け具8が駆動部5の前進による掘削の邪魔になる場合は、案内部4から取外してもよい。その後の掘削により次のロッド継足しが必要となった時は、駆動部5を先行ロッド7から分離し且つロッド7の長さ以上の距離だけ後退させ、削孔機1の案内部に受入れ空間40を作り、ロッド継足し操作の1サイクルを完了する。その後のロッド継足しは、以上説明した機械化装着と機械化心合せ又は未機械化心合せとを反復して行う。
【0015】
削孔機1からロッド7を離脱させるには、先ず離脱すべきロッド7を削孔機1の案内部4に引上げて先行ロッド7及び駆動部5との結合から解除する。次に、前方傾斜ジャッキ12f1及び後方傾斜ジャッキ12r1の長さに比して前方送受ジャッキ12f2及び後方送受ジャッキ12r2を短くし、図4(C)に示すようにラック15を削孔機1の掘削軸線16から下降する向きに傾ける(β<0゜、例えば−5゜)。案内部5内で先行ロッド7及び駆動部5から解除されているロッド7をラック15へ図4(C)の矢印Rのようにり手動で離脱させることもできる。この離脱のために、ハンマー等により手動で図4(C)の矢印Sのようにラック15向きの力をロッド7へ加えてロッド7を離脱させることができる。よって、ロッド7を人手による運搬なしに機械により離脱させることができる。図5を参照して以下に説明する揺動軸20により揺動できる受け部8を用いるならば、離脱すべきロッド7をこの揺動により案内部4からラック15へ離脱させることにより、ロッド離脱を全て機械化できる。
【0016】
こうして、本発明の目的である「ロッドの取扱及び心合せを機械化できるロッド着脱装置付き削孔機」の提供が達成される。
【0017】
【実施例】
図1の実施例では、第1ラック15及び第2ラック15からなるラック対の3対を枠装置13により間隔をおいて上下に配置し、各対に5本のロッドを載置し、単一のロッド棚装置10に15本のロッド7を支持する。枠装置13は、ロッド7の両端対向部位に柱部材13と梁部材13とによって方形垂直枠を形成し、連結部材13によりラック対を適当な上下間隔で方形枠にピン止めするものである。各ロッド7の長さが20mであれば、一つのロッド棚装置10を削孔機1に併置することにより、深さ300m(15×20m)までの孔を一気に掘ることができる。所要の口径と長さのロッド7を必要な数だけ載置したロッド棚装置10を工場で一旦組立てた後分解して、これを削孔現場へ直送することができる。この場合には、現場で削孔機1を据付け、削孔機1の脇に各ジャッキ12を個別に取付け、その後に工場から分解輸送されたロッド棚装置10を組立ててジャッキ12に取付ければ、据付が完了し掘削作業を開始できる。従って、掘削の準備が簡単になり工事期間の短縮を図ることができる。
【0018】
図3、図4及び図5を参照するに、削孔機1に掘削軸線16と平行な揺動軸20を設け、案内部4の受入れ空間40におけるこの揺動軸20と一体に案内突条9を取付けてもよい。嵌合部37付きの可動受け具8を連結鎖38で案内部4の固定部分に取付け、その嵌合部37を手動で案内突条9へ嵌合させ、矢印Sで示されるハンマー等の力により受け具8を案内突条9から分離することができる。この場合には、図5に陰影を付した嵌合部37の一方の顎部37Lを省略する。案内突条9からの可動受け具8の分離のための矢印Sの力を、案内部に取付けた適当なばね装置(図示せず)の弾性力に置換えてもよい。また、案内突条9を掘削軸線16に平行な案内レールとし、可動受け具8をその案内レールに沿って摺動させてもよい。揺動軸20の一端に揺動手段21(図3)を取付け、削孔機1からラック15へのロッド7の移動を、手動の矢印Sの力によってではなく、揺動手段21で駆動する揺動軸20の揺動によるものとして機械化してもよい。
【0019】
図4及び図6において、ラック15に多数のロッド7を載置する場合には、隣接載置位置の間に上下動爪26を設け、隣接ロッド7間に間隔を保ちつつ各ロッド7を隣接載置位置へ順次移動させることができる。この順次移動を一斉に行わせるため、各上下動爪26を二股31を介して連結ロッド30に接続し、駆動装置34により連結ロッド30を図6の矢印Hのように移動させ、連結ロッド30の同図で右向きの移動により二股31を介して爪26をラック15の表面下に引下げてロッド7の移動を許容し、左向きの移動により爪31をラック15の表面上方位置へ復帰させロッド7の移動を制限する。図中32は二股31の枢支ピン、33は二股31を爪26及び連結ロッド30へ枢着する連結ピンである。図示例のラック15は、削孔機1側の端部に引下げ手段28で駆動される装填爪27を有し、反対側の端部にロッド7の落下を防止する突起25を有する。
【0020】
【発明の効果】
以上詳細に説明したように本発明のロッド着脱装置付き削孔機は、ロッドが載置されるラックからなるロッド棚装置を削孔機に併置した複数のジャッキにより傾斜可能に保持して削孔機に対するロッドの着脱を機械化するので、次の顕著な効果を奏する。
【0021】
(イ)60kgにも達することのある重いロッドの取扱を機械化し、作業員を手動による重量物取扱から解放することができる。
