Abstract

PURPOSE:To drill a hole at a required angle and at a position intended for drilling by controlling the posture of a drilling machine which is length- adjustable and suspendible with a post. CONSTITUTION:A suspension part 11 is pivoted with a frame 6 which forms an equipment base 2 in such a fashion that a length adjustable post 12 may be positioned at an edge of a squared cone where an engagement member 13 is installed to the top. The post 12 is fixed with a removable pin 14 by slidingly fitting a small-sized pipe 12b into a large-sized pipe 12a, thereby making adjustable the length of the post. The suspension part 11 of a drilling machine 1 is suspended with a crane car 10 or the like and the drilling machine is adapted to confront a side slope 20, for example, and aligned with a position to be drilled. Furthermore, if a change in the angle of a drilled hole on the side slope 20 is desired, the posture of the drilling machine 1 is accordingly controlled by adjusting the length of the post 12 so that the drilling machine 1 may face the location to be drilled. When the adjustment in the posture of the drilling machine 1 has been finished to comply with the change in the drilled hole, the drilling machine 1 is driven so as to drill a hole.

With respect to the position of the hole drilling machine 32, the boring machine 32 is raised at the tip of the boom 31 and swung in the width direction to maintain the boring machine 32 in a posture that is substantially orthogonal to the slope. A method of drilling on a slope is performed after performing posture control and then performing drilling at multiple points.

Further, a swivel base 30 which can swivel around a vertical axis with respect to the ground, a boom 31 which is provided on the swivel base 30 so as to be able to extend and contract and lie down, and a swing or swivel at the tip of the boom 31. This is a slope face drilling device provided with a swinging table 33 provided and a drilling machine 32 provided so as to be able to rise and fall with respect to the swinging table 33.

[0004]

However, in the above-mentioned conventional apparatus, since the boring machine 32 is attached to the tip of the boom 31, the slope is located above the installation position of the boring machine. In this case, the hole can be drilled, but when the slope is located below and there is no installation site for the drilling device below the slope, there is the disadvantage that it is not suitable for drilling.

Further, in the conventional drilling device, a swivel base 30 which can be swung, a boom 31 which is provided on the swivel base 30 so as to be capable of expanding and contracting and being tilted up and down, can swing or swivel at the tip of the boom 31. Since the swing table 33 is provided and the boring machine 32 is provided so as to be able to rise and fall with respect to the swing table 33, the entire apparatus becomes a dedicated machine and becomes expensive as a whole. There are also inconveniences that cannot be diverted.

In view of the above points, the present invention is to provide a drilling method and an apparatus therefor which solve the above-mentioned conventional inconveniences.
