Description

本発明は、海苔養殖用網を海中で支えるための杭材を海底に打ち込んだり、その他の杭材を地面、海底、湖底、川底などに打ち込んだりする作業に使用する杭打ち機に関する。   The present invention relates to a pile driving machine used for driving a pile material for supporting a seaweed culture net in the sea to the sea bottom, or driving other pile materials to the ground, the sea bottom, a lake bottom, a river bottom or the like.

海苔養殖用網を海中で支えるための杭材を海底に打ち込む作業は、従来、手作業で行われている。具体的には、杭材を船舶に積んで養殖場まで運び込み、船舶上の作業者が杭材を手に持って１本ずつ海底に差し込んでいくという作業が行われている。これらの杭材は一般に外径３８〜５８ｍｍ程度、長さ１０〜１２ｍ程度の合成樹脂製の円筒材が使用されているが、波浪、風及び潮流などによる外力を受ける海中において海苔養殖用網を安定的に支えるためには、杭材の下端から１．５〜２．０ｍ程度までの部分を海底に差し込む必要がある。また、海苔養殖場において使用される杭材の本数も極めて多く、例えば、一つの事業者に係る海苔養殖場で数万本の杭材が使用されることも少なくない。   Conventionally, the work of driving piles to support the seaweed culture nets in the sea has been performed manually. Specifically, a pile material is loaded on a ship, carried to a farm, and an operator on the ship holds the pile material in his hand and inserts it into the seabed one by one. These piles are generally made of synthetic resin cylinders with an outer diameter of about 38 to 58 mm and a length of about 10 to 12 m. In order to support it stably, it is necessary to insert the part from the lower end of a pile material to about 1.5-2.0m in the seabed. In addition, the number of pile materials used in a laver farm is extremely large. For example, tens of thousands of pile materials are often used in a laver farm for one company.

従って、これらの杭材を海底に打ち込む作業には膨大な手間と時間が費やされており、海に浮かぶ不安定な船舶上において、多数の杭材を手作業で差し込んでいる作業者の肉体的負担も大きなものとなっている。   Therefore, enormous effort and time are spent on driving these pile materials into the sea floor. The body of an operator who manually inserts many pile materials on an unstable ship floating in the sea. The burden on the work is also large.

一方、陸上における杭打ち作業を容易化したり、効率化したりするため、動力源としてモータを動力源とする「杭打ち装置」（例えば、特許文献１参照。）あるいはエンジンを動力源とする「杭打ち機」（例えば、特許文献２参照。）などが提案されている。特許文献１記載の「杭打ち装置」あるいは特許文献２記載の「杭打ち機」を使用すれば、杭打ち作業を安全かつ効率的に行うことができ、作業者の肉体的負担を大幅に軽減することができる。   On the other hand, in order to facilitate or increase the efficiency of pile driving on land, a “pile driving device” using a motor as a power source (see, for example, Patent Document 1) or a “pile” using an engine as a power source. A hitting machine "(see, for example, Patent Document 2) has been proposed. By using the “pile driver” described in Patent Document 1 or the “pile driver” described in Patent Document 2, the pile driving work can be performed safely and efficiently, and the physical burden on the worker is greatly reduced. can do.

特開２００１−２７９６６９号公報JP 2001-279669 A 特開２０００−３０００３９号公報JP 2000-300039 A

特許文献１記載の「杭打ち装置」や特許文献２記載の「杭打ち機」はいずれも、打ち込み対象である杭材の上端部を押打することによって当該杭材を地中へ打ち込む方式であるため、比較的短い杭材の打ち込み作業には好適であるが、海苔養殖用網を支える杭材のように長さが１０ｍを超える長尺の杭材を打ち込む作業には不向きである。即ち、打ち込み作業開始時、長尺の杭材の上端部は人間の手の届かない高い位置にあるため、特許文献１記載の「杭打ち装置」や特許文献２記載の「杭打ち機」を使用して杭打ち作業を行うことは、実用上、不可能である。   Both the “pile driving device” described in Patent Document 1 and the “pile driving machine” described in Patent Document 2 are methods of driving the pile material into the ground by pushing the upper end of the pile material to be driven. Therefore, it is suitable for a relatively short pile material driving operation, but is not suitable for a long pile material exceeding 10 m in length, such as a pile material supporting a nori culture net. That is, at the start of the driving operation, the upper end of the long pile material is at a high position that is not reachable by human hands. Therefore, the “pile driver” described in Patent Document 1 and the “pile driver” described in Patent Document 2 are used. It is practically impossible to use the pile driving work.

本発明が解決しようとする課題は、比較的長尺の杭材の打ち込み作業を安全かつ効率的に行うことができ、使い方が簡単であり、作業者の肉体的負担も軽減することができる杭打ち機を提供することにある。   The problem to be solved by the present invention is a pile in which a relatively long pile material can be driven safely and efficiently, its usage is simple, and the physical burden on the operator can be reduced. To provide a hammer.

本発明の杭打ち機は、起立状態にある杭材の外周を着脱可能に把持する把持具を有するクランプ機構と、前記クランプ機構を昇降可能に保持する本体部と、前記クランプ機構を介して前記杭材に打ち込み力を加えるため前記本体部に付設された押打機構と、前記押打機構を作動させるため前記本体部に付設された駆動機構と、を備えたことを特徴とする。   The pile driving machine of the present invention includes a clamp mechanism having a gripping tool that detachably holds an outer periphery of a pile material in an upright state, a main body portion that holds the clamp mechanism to be movable up and down, and the clamp mechanism through the clamp mechanism. A pressing mechanism attached to the main body for applying driving force to the pile material, and a drive mechanism attached to the main body for operating the pressing mechanism.

このような構成とすれば、起立状態にある杭材の外周の任意の位置をクランプ機構の把持具で把持し、駆動機構で作動する押打機構によりクランプ機構を介して当該杭材に打ち込み力を加えれば、クランプ機構とともに杭材が下降するため、地面や海底などへ杭材を打ち込むことができる。この場合、杭材の上端部を保持したり、押打したりする必要がないので、比較的長尺の杭材であっても、打ち込み作業を安全かつ効率的に行うことができる。また、杭材の外周の任意の位置をクランプ機構の把持具で把持し、駆動機構で押打機構を作動させれば良いので、使い方は簡単であり、作業者の肉体的負担も軽減することができる。   With such a configuration, an arbitrary position on the outer periphery of the pile material in an upright state is gripped by the gripping tool of the clamp mechanism, and a driving force is applied to the pile material via the clamp mechanism by a pushing mechanism operated by the drive mechanism. Since the pile material descends together with the clamp mechanism, the pile material can be driven into the ground or the seabed. In this case, since it is not necessary to hold or push the upper end of the pile material, the driving operation can be performed safely and efficiently even with a relatively long pile material. In addition, it is only necessary to hold any position on the outer circumference of the pile material with the clamp mechanism gripping tool and operate the pushing mechanism with the drive mechanism, so the usage is simple and the physical burden on the operator is reduced. Can do.

ここで、前記押打機構として、往復運動することによって前記クランプ機構の少なくとも一部を間欠的に押打する槌状部材を設ければ、簡素な機構でありながら、クランプ機構を介して杭材に確実な押打力を与えることができる。また、槌状部材の質量を増減することにより、押打力を増減することもできる。   Here, as the pushing mechanism, if a hook-like member that intermittently pushes at least a part of the clamp mechanism by reciprocating is provided, the pile material is interposed via the clamp mechanism, although it is a simple mechanism. A certain punching force can be given to. Further, the pressing force can be increased or decreased by increasing or decreasing the mass of the bowl-shaped member.

また、前記槌状部材の押打時の衝撃を緩和する緩衝機構を前記押打機構に設ければ、押打時に発生する衝撃音や振動などを低減することができるため、作業環境の向上に有効であり、作業者の負担を軽減することができる。また、槌状部材によって押打される部分の損傷を抑制することもできる。   In addition, if a shock-absorbing mechanism is provided in the punching mechanism to alleviate the impact at the time of punching of the hook-shaped member, it is possible to reduce the impact sound and vibration generated at the time of punching, thus improving the working environment. It is effective and can reduce the burden on the operator. In addition, it is possible to suppress damage to the portion pressed by the hook-shaped member.

一方、前記把持具が前記クランプ機構に着脱可能な構成とすれば、打ち込み作業の対象である杭材の種類やサイズ（外径、長さなど）に応じて把持具の取り替えが可能となるため、汎用性が高まる。また、把持具をクランプ機構から取り外せば、サイズがコンパクト化するため、施工現場への搬入・撤収時の取り扱い性が良好となるほか、不使用時の保管スペースの削減にも有効である。   On the other hand, if the gripping tool is configured to be detachable from the clamp mechanism, the gripping tool can be replaced according to the type and size (outer diameter, length, etc.) of the pile material to be driven. Increased versatility. In addition, if the gripping tool is removed from the clamping mechanism, the size is reduced, so that handling at the time of carrying in and withdrawal from the construction site is good, and it is also effective in reducing storage space when not in use.

さらに、作業者が把持可能な複数の取っ手を前記本体部若しくはこれと一体化した部材に設ければ、少なくとも１人の作業者が左右の手で取っ手を把持して安定した姿勢で杭打ち作業を行うことが可能となるため、作業性及び安全性が向上する。   Furthermore, if a plurality of handles that can be grasped by an operator are provided on the main body or a member integrated therewith, at least one operator grasps the handle with left and right hands and piles up in a stable posture. Therefore, workability and safety are improved.

本発明により、比較的長尺の杭材の打ち込み作業を安全かつ効率的に行うことができ、使い方が簡単であり、作業者の肉体的負担も軽減することができる杭打ち機を提供することができる。   According to the present invention, there is provided a pile driving machine capable of safely and efficiently driving a relatively long pile material, simple to use, and capable of reducing the physical burden on an operator. Can do.

Each of the movable portion 17a and the fixed portion 17b has a hook shape suitable for gripping the columnar pile material 11, and a plate-like elastic material 17d having a non-slip function is attached along each inner peripheral surface. ing.

押打機構１４は、本体部１３に固定された円筒状のガイド部材１８と、ガイド部材１８内にその軸心方向にスライド可能に配置されたスライダ３１と、スライダ３１の上端部とクランク軸３２とを連接するロッド部材３３と、スライダ３１の下端部に設けられた槌状部材１６と、を備えている。ロッド部材３３の上端軸受け部３３ａは、ギヤードモータ１５によって回転駆動されるクランク軸３２の公転軸３２ａに軸支され、下端軸受け部３３ｂはピン３４を介してスライダ３１の上端部に軸支されている。クランク軸３２及びその周辺の部材はハウジング３８内に収容されている。   The pushing mechanism 14 includes a cylindrical guide member 18 fixed to the main body 13, a slider 31 slidably disposed in the guide member 18 in the axial direction thereof, an upper end portion of the slider 31, and a crankshaft 32. And a rod-shaped member 16 provided at the lower end portion of the slider 31. The upper end bearing portion 33 a of the rod member 33 is supported by the revolving shaft 32 a of the crankshaft 32 that is rotationally driven by the geared motor 15, and the lower end bearing portion 33 b is supported by the upper end portion of the slider 31 via the pin 34. Yes. The crankshaft 32 and its peripheral members are accommodated in a housing 38.

スライダ３１の下端部から突出した状態に設けられた槌状部材１６は、スライダ３１に対し軸心方向に沿って距離１６ｄだけスライド可能に取り付けられ、コイルバネ３５によってスライダ３１下端部から突出する方向へ付勢されている。また、本体部１３に一体的に固定された押打機構１４のガイド部材１８の左右側面からそれぞれ水平方向に円柱状の取っ手１９が延設されている。   The hook-like member 16 provided so as to protrude from the lower end portion of the slider 31 is attached to the slider 31 so as to be slidable by a distance of 16 d along the axial direction, and is protruded from the lower end portion of the slider 31 by the coil spring 35. It is energized. In addition, columnar handles 19 extend in the horizontal direction from the left and right side surfaces of the guide member 18 of the pushing mechanism 14 that is integrally fixed to the main body 13.

図６，図７に示すように、座板２５に設けられたインデックスプランジャ３０を解除して、レバー２７基端の操作部２７ｂを支軸２６中心に下方へ回動させ、レバー２７先端の鈎状のフック部２７ａを可動部１７ａに突設されたストッパ２９から離脱させ、可動部１７ａを支軸１７ｃ中心に回動させると、把持具１７は開いた状態となる。この状態で、固定部１７ｂと可動部１７ａとの間に杭材１１を挟み込んで可動部１７ａを閉じ、レバー２７基端の操作部２７ｂを支軸２６中心に上方へ回動させ、フック部２７ａをストッパ２９に係合させ、レバー２７の操作部２７ｂ側のＵ字状の切欠部２７ｃをインデックスプランジャ３０に係合させれば、クランプ機構１２によって杭材１１が起立姿勢で把持された状態となる。   As shown in FIGS. 6 and 7, the index plunger 30 provided on the seat plate 25 is released, and the operating portion 27 b at the base end of the lever 27 is rotated downward about the support shaft 26, so that When the hook-shaped hook portion 27a is detached from the stopper 29 protruding from the movable portion 17a and the movable portion 17a is rotated about the support shaft 17c, the gripping tool 17 is opened. In this state, the pile material 11 is sandwiched between the fixed portion 17b and the movable portion 17a to close the movable portion 17a, and the operation portion 27b at the base end of the lever 27 is rotated upward about the support shaft 26, thereby the hook portion 27a. Is engaged with the stopper 29, and the U-shaped notch 27c on the operating portion 27b side of the lever 27 is engaged with the index plunger 30, and the pile material 11 is held in a standing posture by the clamp mechanism 12. Become.

杭打ち現場おいて、作業者が一対の取っ手１９を左右の手で把持し、杭材１１が起立状態を保つような姿勢で杭打ち機１０を保持した後、ギヤードモータ１５を作動させるとクランク軸３２の回転によってロッド部材３３を介してスライダ３１及び槌状部材１６がガイド部材１８内を軸心方向に往復運動する。これにより、槌状部材１６の下端部が、クランプ機構１２の一部をなすクランプセット金具２２の上面を間欠的に押打し、この押打力がクランプセット金具２２、固定軸２３及び把持具１７を介して杭材１１に伝わり、杭材１１は鉛直下方に向かって打ち込まれていく。   When the operator grips the pair of handles 19 with the left and right hands and holds the pile driving machine 10 in such a posture that the pile material 11 is kept upright at the pile driving site, The rotation of the shaft 32 causes the slider 31 and the bowl-shaped member 16 to reciprocate in the axial direction in the guide member 18 via the rod member 33. As a result, the lower end portion of the bowl-shaped member 16 intermittently pushes the upper surface of the clamp set metal fitting 22 that forms a part of the clamp mechanism 12, and this pushing force is applied to the clamp set metal fitting 22, the fixed shaft 23, and the gripping tool. It is transmitted to the pile material 11 through 17, and the pile material 11 is driven toward the vertically downward direction.

杭打ち作業の進行に伴い、杭打ち機１０は杭材１１と共に下降していくので、その一部が水面や地面に接するなどして、杭打ち作業が続行できなくなった時点でギヤードモータ１５を停止する。そして、クランプ機構１２のレバー２７を前述のように操作して把持具１７を開閉させ、杭材１１に対する把持具１７の位置を適切な位置まで引き上げた後、ギヤードモータ１５を作動させれば、杭打ち作業を再開することができる。杭材１１の長さ、地盤の状況あるいは打ち込み深さなどに応じて、前述した作業を繰り返せば、杭材１１が長尺であっても適切な深さまで打ち込むことができる。   As the pile driving work progresses, the pile driving machine 10 descends together with the pile material 11, so that when the pile driving work cannot be continued due to a part of the pile driving machine coming into contact with the water surface or the ground, the geared motor 15 is turned off. Stop. And if the lever 27 of the clamp mechanism 12 is operated as described above to open and close the gripping tool 17 and raise the position of the gripping tool 17 with respect to the pile material 11 to an appropriate position, then the geared motor 15 is operated, Pile driving work can be resumed. If the above-described operation is repeated according to the length of the pile material 11, the ground condition, or the driving depth, the pile material 11 can be driven to an appropriate depth even if it is long.

このように、起立状態にある杭材１１の外周の任意の位置をクランプ機構１２の把持具１７で把持し、駆動機構（ギヤードモータ１５）で作動する押打機構１４によりクランプ機構１２を介して当該杭材１１に打ち込み力を加えれば、クランプ機構１２とともに杭材１１が下降するため、地面や海底などへ杭材１１を打ち込むことができる。この場合、杭材１１の上端部を保持したり、押打したりする必要がないので、比較的長尺の杭材１１であっても、打ち込み作業を安全かつ効率的に行うことができる。また、杭材１１の外周の任意の位置をクランプ機構１２の把持具１７で把持し、駆動機構（ギヤードモータ１５）で押打機構１４を作動させれば良いので、使い方は簡単であり、作業者の肉体的負担も軽減することができる。   In this way, an arbitrary position on the outer periphery of the pile material 11 in the standing state is gripped by the gripping tool 17 of the clamp mechanism 12, and the punching mechanism 14 operated by the drive mechanism (geared motor 15) is used via the clamp mechanism 12. If a driving force is applied to the pile material 11, the pile material 11 descends together with the clamp mechanism 12, so that the pile material 11 can be driven into the ground or the seabed. In this case, since it is not necessary to hold or push the upper end portion of the pile material 11, even if the pile material 11 is relatively long, the driving operation can be performed safely and efficiently. Moreover, since the arbitrary position of the outer periphery of the pile material 11 should be hold | gripped with the holding tool 17 of the clamp mechanism 12, and the pushing mechanism 14 should just be actuated with a drive mechanism (geared motor 15), the usage is easy and work The physical burden on the person can also be reduced.

また、押打機構１４において、スライダ３１にスライド可能に取り付けられた槌状部材１６を、コイルバネ３５によってスライダ３１下端部から突出する方向へ付勢することにより、槌状部材１６がクランプセット金具２２を押打するときの衝撃を緩和する緩衝機構を形成している。これにより、杭打ち作業中に槌状部材１６がクランプセット金具２２を押打するときに発生する衝撃音や振動などを低減することができるため、作業環境の向上に有効であり、作業者の負担を軽減することができる。また、槌状部材１６によって押打されるクランプセット金具２２の上面部分の損傷を抑制することもできる。   Further, in the pushing mechanism 14, the hook-like member 16 slidably attached to the slider 31 is biased by the coil spring 35 in a direction protruding from the lower end portion of the slider 31, so that the hook-like member 16 is clamped to the clamp set fitting 22. A shock-absorbing mechanism is formed to mitigate the impact when pushing. As a result, it is possible to reduce the impact sound and vibration generated when the saddle-like member 16 strikes the clamp set fitting 22 during the pile driving operation, which is effective in improving the work environment. The burden can be reduced. Further, it is possible to suppress damage to the upper surface portion of the clamp set metal fitting 22 that is pressed by the hook-shaped member 16.

さらに、クランプ機構１２を構成する把持具１７は、クランプセット金具２２上面に螺着されたボールプランジャ３７を緩めることにより、クランプセット金具２２に着脱可能である。従って、打ち込み作業の対象である杭材１１の種類やサイズ（外径、長さなど）に応じて把持具１７の取り替えが可能であり、汎用性が高い。また、把持具１７をクランプセット金具２２から取り外せば、サイズがコンパクト化するため、施工現場への搬入・撤収時の取り扱い性が良好となり、不使用時の保管スペースの削減にも有効である。   Furthermore, the gripping tool 17 constituting the clamp mechanism 12 can be attached to and detached from the clamp set fitting 22 by loosening a ball plunger 37 screwed onto the upper surface of the clamp set fitting 22. Therefore, the gripping tool 17 can be replaced according to the type and size (outer diameter, length, etc.) of the pile material 11 that is the target of the driving work, and the versatility is high. In addition, if the gripping tool 17 is removed from the clamp set metal fitting 22, the size is reduced, so that handling at the time of carrying in / withdrawing to the construction site becomes good, and it is effective in reducing storage space when not in use.

また、本体部１３に一体的に固定された押打機構１４のガイド部材１８の左右側面からそれぞれ水平方向に円柱状の取っ手１９が延設されているため、少なくとも１人の作業者が左右の手で取っ手１９を把持して安定した姿勢で杭打ち作業を行うことができ、作業性及び安全性を向上させることができる。   In addition, since the cylindrical handle 19 extends horizontally from the left and right side surfaces of the guide member 18 of the pushing mechanism 14 that is integrally fixed to the main body 13, at least one operator can Pile driving work can be performed in a stable posture by gripping the handle 19 by hand, and workability and safety can be improved.

本発明の杭打ち機は、海苔養殖用網を海中で支えるための杭材を海底に打ち込む作業あるいはその他の杭材を地面、海底、湖底、川底などに打ち込む作業などにおいて広く利用することができる。   The pile driving machine of the present invention can be widely used in the operation of driving pile materials for supporting the seaweed culture nets in the sea or the operation of driving other pile materials into the ground, seabed, lake bottom, riverbed, etc. .
