Robot control connector-Connector connected to 36-
And a box 55 for accommodating a slider to be described later.
And a television camera 56, an illumination 57, a laser marker 58, and the like attached to the lower rear end of the box 55.

The moving section 52 of the working robot 50 has three sliders 59, 60, and 61, a bed 62 fixed to the lowermost slider 61, and a bed 62.
A spindle base 64 slidable by a cylinder 63 therein, and spindle driving motors 65, 65 and spindles 66, 6 attached to the spindle base 64.
6, a drilling machine 6 attached to the front end of the spindle 66
7, 67, a stopper arm 68 fixed to the bed 62, a stopper 69 fixed at the center of the tip of the stopper arm 68, and a spindle base 64 from the bed 62 side. A drilling depth adjusting bolt 70 for restricting the movement of the spindle base 64 is provided.

As described above, the working robot 50 for punching the mounting hole of the footrest tool is provided with the fixing portion of the working robot 50 from the opening side of the top rail 23 on the turning base 11 as described above. 51 is fixedly set on the trolley 5, and the motor 33 is driven via the relay box 34 by remote control to lower the trolley 5, and the work robot 5 set on the trolley 5
The laser marker 58 detects the position of 0 facing the wall surface to be pierced in the manhole 2 and the motor 33 detects the position.
Is stopped and the carriage 5 is held on the rail 3.

In this state, each slider-air cylinder 71, 7 is further remotely controlled via the relay box 34.
The sliders 59, 60, 61 are pushed out of the box 55 toward the wall surface of the manhole 2 by operating the sliders 2, 73, and the stopper 69 at the end of the stopper arm 68 is provided.
To the wall of the manhole 2.

When it is confirmed that the stopper 69 has come into contact with the wall surface of the manhole 2, the spindle driving motors 65, 65 are driven to drive the spindles 66, 66.
Is rotated to advance the spindle base 64 toward the wall surface of the manhole 2, and the boring machines 67, 67 are moved to the manhole 2.
And water is sprayed from between the pits at the tip of each drilling machine 67. This drilling machine 67, 67
The desired holes are pierced by the pits due to the rotational advance, and the fine powder of the broken concrete is absorbed by the jetted water, so that the scattering of the fine powder is considerably reduced. In addition,
Numerals 74, 74 are covers for preventing fine powder from being scattered, which are respectively disposed on the sides of the stopper 69.

When a hole having a desired depth is formed, the spindle base 64 is advanced by moving the spindle base 64 forward.
The front surface of the hole 4 is provided with a drilling depth adjusting bolt 70 provided on the bed 62.
Advancing the spindle base 64, i.e. each punch 6
7 is regulated, and compressed air is injected from between the pits at the tip of each drilling machine 67. Cleaning of the perforated hole is performed by the injection of the air. The depth of the hole to be drilled can be freely adjusted by moving the drilling depth adjusting bolt 70 forward and backward.

After the inside of the hole is cleaned, the spindle drive motors 65, 65 are driven in reverse to move the spindle base 64 back from the wall surface of the manhole 2 and the boring machines 67, 67 to the manhole. -Pull it out of the wall of Rule 2. In this way, when the mounting hole of one footrest is completed,
The motor 33 is driven via the relay box 34 by remote control to lower the carriage 5 to a position where the mounting hole of the next footrest is drilled, and the driving of the motor 33 is stopped at that position. The carriage 5 is held on the rail 3, and the mounting hole of the footrest is drilled by the same operation as described above.

As shown in FIGS. 4 and 5, the drilling machine 67 has a plurality of fluid passages 81, 8 near the center of the cylindrical body 80.
And a plurality of diamond pits 82 are arranged along the outer peripheral edge of the cylindrical body 80, and a plurality of diamond pits are provided toward the center on the inner diameter side of the pit 82 at the outer peripheral edge. Are arranged.

Therefore, the boring machine 67 is connected to the manhole 2.
When rotating while pressing against the wall surface of the cylindrical body, the diamond pits 82 and 83 cooperate to reliably form a cylindrical hole, and water or air squirts radially from the fluid passage 81 at the center of the cylindrical body 80. The perforation operation and post-perforation cleaning can be made very easy.

A large-diameter cylindrical body 84 for holding the cylindrical body 80 is provided at a rear portion of the cylindrical body 80, and a plurality of diamonds are also provided along the outer peripheral edge of the large-diameter cylindrical body 84. When the pits 85, 85... Are arranged, a large-diameter cylindrical hole is surely drilled by the pit 85, and the diamond pits 82, 83 and 85 cooperate to drill two large and small holes. Will be.
