Abstract

PURPOSE:To enable a drill part to cope with any shaped slate by enabling a three dimensional posture of the drill part to be taken by a method wherein a piercing part equipped with a drill part for providing a dug ditch for cutting stone to a lower end part is fitted freely vertically movably to a connecting shaft protruded from an outer jacketing cylinder part of a vertically movable cylinder and, in a freely pivotally manner, around the connecting shaft. CONSTITUTION:A piercing part 8 is freely vertically movable, freely rotatably around a shaft line, and in a freely pivotal manner, in a right and left direction. After transferring a piercer A, a frame body for hanging a piercing part 3 is moved along a front and rear frame above a supporting frame of the piercer. A supporting piece 5 of the piercing part is moved along a horizontal member rail part 4 to execute fine regulation of a position of the piercing part 8. Then, a vertically movable cylinder 6 is rotated around the shaft line to determine an arranged direction of a drill part of the piercing part 8 in a required direction. Then, the horizontal member rail part 4 is swung by a specific angle around a shaft-supporting part 31, and the piercing part 8 is inclined obliquely and upward together with the cylinder 6. Further, a base end of the cylinder 6 is swung in front and in rear, swung while lowering the piercing part 8 with the cylinder 6, and the drill is made to abut on a slate.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention is for breaking a stone board.
The present invention relates to a quarrying machine for quarrying, which is capable of piercing a plurality of digging holes in a row on a stone board.

[0002]

2. Description of the Related Art Conventionally, there are some quarrying machines for quarrying, which enable a large number of excavation holes to be formed in a row on a stone bed in a state perpendicular to the surface of the stone bed.

A wedge or the like is driven into the hole so that the stone bed can be cut into a predetermined size along the hole.

Such a punching machine is mounted on a base or the like which can be installed on a stone bed. When installing the drilling machine on the stone bed, the base is placed on the stone bed and the drill of the drilling machine is rotated. While descending vertically, the holes are drilled on the stone bed.

However, the surface of the stone bed is not always horizontal, and in the case of breaking a stone bed with an inclined surface, in order to provide a vertical hole to the stone bed surface, a base having an excavator is mounted on the stone bed. Must be placed diagonally,
It is extremely difficult to mount the base in an inclined state.

[0006] Therefore, it has been developed to hang a suspension frame on a hook provided at the tip of a boom of a crane or the like via a chain or the like so that the suspension frame can be tilted left and right, and an excavator is attached to the lower end of the suspension frame. It was

[0007]

However, the quarry boring machine having the above-mentioned suspension frame still has the following problems.

That is, since it is suspended through a chain or the like, it becomes unstable during drilling work, smooth drilling work cannot be performed, and the drilling machine moves due to vibrations caused by rotation of the drill. Could damage the drill.

An object of the present invention is to provide a quarry boring machine that can solve the above problems.

[0010]

SUMMARY OF THE INVENTION According to the present invention, a perforator support frame is movably arranged on rails arranged side by side at regular intervals, and the perforation part is suspended above the perforator support frame. The frame body is movably arranged in a direction orthogonal to the moving direction of the punching machine support frame, and the horizontal rail portion is provided in the same direction as the moving direction of the punching machine support frame in the drilling section suspension frame body. Along with being mounted on the shaft, it is not swingable around the axis line.The perforation part support piece is slidably attached to the horizontal rail part, and the lifting cylinder can be rotated around the axis line on the lower surface of the perforation part support piece. In addition, the drilling portion support piece is swingably connected in the sliding direction, and the connecting shaft protruding from the exterior cylinder portion of the lifting cylinder is provided with a drill portion at the lower end for providing a stone cutting hole in the stone masonry. The boring part is mounted so that it can be raised and lowered and can be swung around the connecting shaft. Those relating to the machine.
