ところで、このような堀削機は従来クローラ等
の履帯で走行するものがほとんどであるが、既存
建物が近接する作業スペースの狭い場所では操作
ができない。 By the way, although most of these excavators conventionally run on tracks such as crawlers, they cannot be operated in narrow working spaces near existing buildings.
そこで、本発明者は先に堀削予定位置の両側に
沿つて軌条１０を配設し、この上を堀削機を走行
させるものを開発した。 Therefore, the inventor of the present invention first developed a system in which rails 10 are provided along both sides of the planned excavation position, and the excavation machine runs on the rails 10.
このように軌条走行用とすることで、図示のご
とく油圧ユニツト８は別の台車９に分け、機体２

うな地上に反力をとるアウトリガーでは大きく張
出さなければ効果がなく、これを設けることでせ
つかくのコンパクト性が損なわれてしまう。[Problems to be Solved by the Invention] Usually, many construction machines are provided with outriggers using hydraulic cylinders to ensure stability during work. However, as mentioned above, in a track-driven excavator, the machine body 2 is made as small as possible, so an outrigger like this that takes a reaction force on the ground is ineffective unless it is extended greatly, so by providing this, Compactness is lost.
また、アウトリガーを設けないで堀削時の反力
をとる方法としては、機体２を含めて全体を大重
量物とすることが考えられるが、これでは機動性
がきわめて悪くなる。 Further, as a method of absorbing the reaction force during excavation without providing an outrigger, it is possible to make the entire machine including the body 2 a heavy object, but this would result in extremely poor maneuverability.
さらに、機体２等を軽量化して機動性を確保
し、軌条１０をアンカーボルト等で強固に支持す

も考えられるが、軌条１０は堀削進行に合わせて
順次撤去と設置が繰り返すため、アンカーボルト
等の打込み、引抜きに時間がかかり軌条１０の設
置作業が煩雑となり手間がかかるものとなる。 Furthermore, it is possible to take the reaction force from the rail 10 by reducing the weight of the fuselage 2, etc. to ensure maneuverability, and firmly supporting the rail 10 with anchor bolts, etc.; At the same time, since removal and installation are repeated, it takes time to drive and pull out anchor bolts, etc., making the installation work of the rail 10 complicated and time-consuming.
本発明の目的は前記従来例の不都合を解消し、
堀削機全体を小型に形成しながらも、簡単に堀削

想的な支持が得られる。 When such digging is performed, the engaging means 1
The horizontal jack 14 of No. 5 is extended and its tip is strongly pressed against the wall surface 12a of the guide wall 12. As a result, the engaging means 15 is also spanned between the guide walls 12, 12, and fixes the machine body 2. Therefore, the guide wall 12 acts as a reaction force against the force that the excavator receives during excavation. can be supported. In addition, since the center of the engaging means 15 coincides with the center of the excavating machine, that is, the center of the casing 7 to be built into the ground, the engaging means 15 does not receive any damage from the excavating resistance generated when the casing 7 rotates. The rotational torque is evenly applied to the engaging means 15 without biasing to one side, and even a small jack 14 can provide ideal support for the excavating machine.
