Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-perforating apparatus for providing an anchor hole or the like in a tunnel wall or a ceiling of various structures.

[0002]

2. Description of the Related Art Heretofore, for example, a wall surface drilling operation for providing an anchor hole in a tunnel wall surface is performed as follows. First, an elevator having a work floor surface on the upper surface is moved and fixed immediately below a tunnel wall surface where an anchor hole is to be provided. An operator gets on a work floor with a desired piercing tool. The lift device is driven to move up and down the elevating platform and move the work floor toward the tunnel wall surface. The operation of the lift device is stopped at a position where the work floor surface is close to the tunnel wall surface. Thereafter, the operator holds and operates the drilling tool by hand and drills a predetermined anchor hole in the tunnel wall surface.

[0003]

However, the wall drilling operation using the above-mentioned lifting platform still has the following problems to be solved. That is, when an anchor hole is accurately provided on the tunnel wall surface, it is necessary to make the axis of the drilling hole orthogonal to the tunnel wall surface. Normally, the tunnel wall has an upwardly convex semi-circular cross-section, so if anchor holes are provided in the ceiling wall that is a substantially horizontal plane or the left and right side walls that are substantially vertical, a drill drill A squareness can be easily obtained. However, it is very difficult to make a right angle of the drilling drill at the inclined wall portion between the ceiling wall portion and the left and right side wall portions, and it has not been possible to accurately drill the anchor hole.

When drilling anchor holes in the ceiling wall, the left and right side walls, and the inclined wall between the ceiling wall and the left and right side walls, the position of the drill must be changed each time. However, since the air motor for driving the drill is formed integrally with the drill, the air motor is quite heavy, and changing the attitude of the drill is a heavy labor.

The present invention has been made in view of such circumstances, and it is possible to accurately drill an anchor hole or the like irrespective of the wall shape to be drilled, and to automatically control the posture of the drill. Accordingly, it is an object of the present invention to provide a wall surface punching device capable of reducing the drilling operation.
