しかし、最近の削孔径の増大基調に伴い、二重管式ドリルロッドの径が大きく なってその重量が増加している。従って、二重管式ドリルロッドの接続，回収作 業を全て人力で行っている現状では、二重管式ドリルロッドの重量の増加に伴い 二重管式ドリルロッドの接続作業時の危険性が増し、又、これを保持するために 大きな労力を必要とされている。そのため、昨今では、上記二重管式ドリルロッ ドの接続作業の安全性と労力の削減が求められている。 However, with the recent trend of increasing drilling diameters, the diameter of double-pipe drill rods has become larger and their weight has increased. Therefore, under the present circumstances where the connection and recovery work of the double-pipe drill rod is all done manually, the danger of connecting the double-pipe drill rod increases as the weight of the double-pipe drill rod increases. A great deal of effort is needed to increase and maintain it. Therefore, in recent years, there has been a demand for safety and labor reduction in connecting work of the double pipe type drill rod.
【０００５】 又、特開平１−２８０１９８号公報には、二重管式ドリルロッドの削孔機への 配置，セットライン上への位置決め及び取出しを自動化して、ドリルロッドの着 脱性能，信頼性を向上し能率を高めるため、削孔機のスライドベース側部に装着 した取付枠に枢着され先端の下側チャックがドリルロッドのセットラインを通る 軌跡で回動される下側アームと、当該下側アームに枢着され先端の上側チャック が上記下側チャックに向かって揺動される上側アームと、上記取付枠と下側アー ム間に連設された回動用シリンダと、上記上，下側アーム間に連設された揺動用 シリンダを具備した削孔機の二重管式ドリルロッド着脱装置が開示されている。Further, Japanese Laid-Open Patent Publication No. 1-280198 discloses automatic placement and removal of a double-tube drill rod on a drilling machine, positioning on a set line, and removal of the drill rod. In order to improve efficiency and efficiency, a lower arm that is pivotally attached to a mounting frame mounted on the side of the slide base of the hole drilling machine and a lower chuck of the tip is rotated in a path that passes through the set line of the drill rod, An upper arm pivotally attached to the lower arm and an upper chuck at the tip of which swings toward the lower chuck; a rotation cylinder connected between the mounting frame and the lower arm; Disclosed is a double pipe type drill rod attaching / detaching device of a hole drilling machine provided with a rocking cylinder continuously provided between lower arms.
【０００６】 しかし乍ら、上記着脱装置は構造が複雑で、又、上記アームを取り付けるとス ライドベース自体が重くなり、スライドベースを受けているピン等に大きな負担 が掛かってしまう欠点があった。 本考案は斯かる実情に鑑み案出されたもので、その目的は、従来の削孔機の構 造に若干の改良を施すことにより、二重管式ドリルロッド等の削孔管を順次接続 する上での作業の安全性と労力の削減を可能とした構造の簡単な削孔機を提供す ることにある。However, the structure of the attachment / detachment device is complicated, and when the arm is attached, the slide base itself becomes heavy, resulting in a large load on the pin or the like receiving the slide base. . The present invention has been devised in view of such circumstances, and its purpose is to connect drilling pipes such as a double pipe drill rod sequentially by slightly improving the structure of a conventional drilling machine. The purpose of the present invention is to provide a drilling machine with a simple structure that enables work safety and labor reduction.

In the hole drilling machine formed as described above, a hammer is rotatably mounted on the guide, and a rotating mechanism for rotating the hammer is provided on the guide.

本考案によれば、ハンマに接続する削孔管の一端に向けてハンマを前後方向へ 移動し、回動機構でハンマを回動させてハンマ軸と削孔管とが同一軸上に位置す るようにハンマの位置を調整すれば、削孔軸線上に削孔管を人力で配置すること なく、ハンマと削孔管との接続が可能となる。 According to the present invention, the hammer is moved in the front-rear direction toward one end of the drilled pipe connected to the hammer, and the hammer is rotated by the rotating mechanism so that the hammer shaft and the drilled pipe are located on the same axis. By adjusting the position of the hammer in this way, it is possible to connect the hammer and the drilled pipe without manually placing the drilled pipe on the drilling axis.
