HILLSIDE DRILLING METHOD
To provide a hillside drilling work vehicle which effectively prevents damage and abrasion of components that constitute the drilling work vehicle, while being able to improve drilling efficiency, and to provide a hillside drilling facility and a hillside drilling method.SOLUTION: In a hillside drilling work vehicle 2 which comprises a work vehicle body 43 which can travel a hillside by itself, and a drilling device 70 which is supported by a tip portion of an arm 45 of the working vehicle body 43, the drilling device 70 comprises a down-the-hole hammer 74, a hydraulic motor 75 which is continuously provided to a base end portion of the down-the-hole hammer 74 and which drives and rotates the down-the-hole hammer 74, and a joint member 60 which supports the drilling device 70 rotatably by centering on two axes of a first axis 61 which is approximately parallel to an arm axis 45a to make the arm 45 rotate in the vertical direction and a second axis 64 which is approximately perpendicular to the first axis 61, is provided between the tip portion of the arm 45 and the drilling device 70.SELECTED DRAWING: Figure 2
【課題】削孔作業車を構成する部品の破損や摩耗を効果的に防止しつつ、削孔効率を向上し得る傾斜地削孔作業車及び傾斜地削孔設備並びに傾斜地削孔方法を提供する。【解決手段】傾斜地を自走可能な作業車本体４３と、作業車本体４３のアーム４５の先端部に支持された削孔装置７０とを備えた傾斜地削孔作業車２であって、削孔装置７０は、ダウンザホールハンマ７４と、ダウンザホールハンマ７４の基端部に連設されて、ダウンザホールハンマ７４を回転駆動する油圧モータ７５とを備え、アーム４５の先端部と削孔装置７０間に、アーム４５の上下方向へのアーム軸４５ａと略平行な第１軸６１と、第１軸６１と略直交する第２軸６４の２軸を中心として、削孔装置７０を回動自在に支持する継手部材６０を設けた。【選択図】図２
