MULTI-SHAFT DRILLING DEVICE
To solve the problem that due to such a conventional configuration as to support excavation shafts by a slide contact body brought into slide contact with a wall surface of an excavation hole, a load applied to a plurality of excavation shafts cannot be sufficiently supported, and the entire excavation shaft cannot be prevented from being rotated with a drive part as a support point.SOLUTION: In a multi-shaft drilling device, a plurality of excavation shafts 7 driven and rotated by a driving device 5 that is liftably mounted on a leader mast 3 provided on a base machine 2 installed on the ground are provided side by side in the driving device 5, outer excavation shafts 7B are provided on both sides of a central excavation shaft 7A in the center of the plurality of excavation shafts 7, the outer periphery of the central excavation shaft 7A in the center in the plurality of excavation shafts 7 is surrounded by a rigid cover 9, an upper part of the rigid cover 9 is mounted on the side of the driving device 5 in a fixed state, and a connection body 10 that integrally connects the respective excavation shafts 7 and the rigid cover 9 is provided on the predetermined lower position of the rigid cover 9.SELECTED DRAWING: Figure 2
【課題】従来、掘削軸を、掘削孔の壁面に摺接する摺接体により支持する構成のため、複数の掘削軸に掛かる荷重を充分に支持できず、複数の掘削軸全体が駆動部を支点に回転するのを防止できないという課題がある。【解決手段】地上に設置されたベースマシン２に設けられたリーダーマスト３に昇降自在に取付けた駆動装置５により駆動回転する掘削軸７を駆動装置５に複数並列状態で設け、この複数の掘削軸７のうち中央の中央掘削軸７Ａの両側に外側掘削軸７Ｂをそれぞれ設け、前記複数の掘削軸７のうち、中央の中央掘削軸７Ａの外周は剛性カバー９により包囲し、剛性カバー９の上部は駆動装置５側に固定状態に取付け、剛性カバー９の下方所定位置には各掘削軸７および前記剛性カバー９とを一体状に連結する連結体１０を設けた多軸掘削装置。【選択図】図２
