DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 is a front view showing an embodiment of the present invention, and FIG.
Are provided in parallel on the side of the drilling machine 21.

The drilling machine 21 mounts a double pipe rod on a drill head (not shown) which advances and retreats along the guide cell 22, and drills by rotating, feeding and hitting the double pipe rod. Since it is conventionally known, a detailed description thereof will be omitted. Reference numeral 23 denotes an outer rod clamp of the drilling machine 21;
Reference numeral 4 denotes an inner rod clamp of the drilling machine 21, which clamps when connecting (adding) a double pipe rod. Reference numeral 25 denotes an inner rod centerizer of the drilling machine 21.

At the right place of the drilling machine 21, the bracket 2
Is fixed and extends laterally, and a raise frame 3 is pivotally attached to the bracket 2 by a pivot 4. A cylinder 5 is connected to and supported by the raise frame 3 so that the cylinder 5 can be turned upside down so that the tilt angle can be freely adjusted.

A shaft 6 is provided on the raise frame 3 in parallel with the drilling machine 21, and a rotary actuator 7 is connected to the shaft 6 so as to be rotated. Since the shaft 6 is provided on the raise frame 3, the shaft 6 tilts with the tilt of the raise frame 3. Therefore, the tilt angle of the shaft 6 can be adjusted by the expansion and contraction of the cylinder attached to the raise frame 3.

The shaft 6 is provided with a rod holder 9, an outer rod clamp 10 and an inner rod clamp 11 via a connecting member 8 sequentially from the front of the excavation. The rod holder 9 holds the double pipe rod R, and the outer rod clamp 10
1 to clamp the inner rod clamp 1
1 is for clamping the inner rod R2. As the rod holder 9, the outer rod clamp 10, and the inner rod clamp 11, conventionally known ones used in a drilling device or the like can be adopted. For example, as shown in FIG. 3, the structure is such that the double pipe rod R is clamped by the clamp pieces 12a, 12b, 12c which advance and retreat toward the center of the rod R.

On the extension of the clamp axis of the rod holder 9, the outer rod clamp 10, and the inner rod clamp 11, an inner rod contact member 13 that moves forward and backward along the extension of the axis is provided. The cylinder 14 is connected to the inner rod contact member, and is moved forward and backward. The inner rod contact member 13 is used to make the inner rod R2 of the double tube rod R protrude (exit) from the outer rod R1 and clamp the inner rod R2 with the inner rod clamp 11.

Thus, the double pipe rod handling apparatus 1 of the above embodiment operates as follows. The double pipe rod R can be set and clamped by being inserted through the rod holder 9, the outer rod clamp 10, and the inner rod clamp 11, and attached. At this time, the inner rod R
2 sets the double pipe rod R and holds it with the rod holder 9, and then causes the inner rod contact member 13 to advance by the cylinder 14, thereby causing the tip to move out of the outer rod R <b> 1 and clamped by the inner rod clamp 11.

The rod holder 9 and the outer rod clamp 1
0 and the inner rod clamp 11 are connected to the shaft 6 via the connecting member 8, and the shaft 6 is rotated by the rotary actuator 7, whereby the rod holder 9, the outer rod clamp 10 and the inner rod clamp 11 are also connected to the shaft 6. You can rotate around. That is, the clamped double tube rod R can also rotate as shown in FIG. FIG. 3 is a schematic arrow view taken along the line AA of FIG. 1 and shows a state where the double pipe rod R clamped by the clamps 10 and 11 is rotated toward the drilling machine 21 and moved. .
At this time, the terminal which is rotated and moved to the drilling machine 21 side is set so that the clamped double pipe rod R is located at the double pipe rod setting position of the drilling center of the drilling machine 21. Therefore, the double pipe rod R clamped by the rod holder 9, the outer rod clamp 10 and the inner rod clamp 11 is rotated by the rotary actuator 7 to be moved to the double pipe rod replenishment position (set position) of the drilling machine 21. Can be.

The rod holder 9, the outer rod clamp 10 and the inner rod clamp 11 are connected to the connecting member 8

The raise frame 3 is pivotably mounted on the cylinder 5
The rod holder 9, the outer rod clamp 10 and the inner rod clamp 11 can be tilted by the cylinder 5 so that the raise frame 3 is tilted by the cylinder 5 so that the rod holder 9, the outer rod clamp 10 and the inner rod clamp 11 can be tilted. Can be adjusted freely. Therefore, the tilted position of the clamped double pipe rod R can be freely adjusted. That is, regardless of the tilt angle of the drilling machine 21, the tilt angle of the double pipe rod handling device 1 can be maintained. For example, since the double pipe rod can be held in the horizontal position regardless of the drilling angle of the drilling machine 21, the double pipe rod can be clamped at the horizontal position, and then the drilling machine 21 can be handled according to the drilling angle of the drilling machine 21.

According to the double pipe rod handling apparatus 1 described above, the clamped double pipe rod R is rotated by the rotary actuator 7 so as to be aligned with the drilling center of the drilling machine 1 and set in alignment. it can. Conversely, when extubation is performed, the double pipe rod R can be recovered by the reverse operation. That is, the rod holder 9, the outer rod clamp 10, and the inner rod clamp 11 are rotated and positioned at the position of the extruded double pipe rod of the drilling machine 21, and after the drilling is clamped, it is rotated in the reverse direction so that the drilling machine 21 rotates. Can be collected.
