DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boring apparatus capable of efficiently performing a boring operation in soil.

[0002]

2. Description of the Related Art As shown in FIG. 6, a mechanism of a conventionally used boring apparatus uses a rotating part d of a driving motor a through a belt b and a speed reducer c and the like. As shown in FIG. 7, a slide shaft e is inserted into the rotating part d so as to be slidable in the vertical direction, and a drilling pipe f is inserted into the slide shaft e. It is a mechanism to be fixed. Then, the slide shaft e is moved by the hydraulic cylinder g.
When the rotating part d and the slide shaft e are driven and rotated while pressing the upper end of the excavator downward, the excavating pipe f advances in the soil while rotating.

[0003]

However, in the above mechanism,
After pressing the slide shaft e by the maximum stroke of the hydraulic cylinder g, the driving rotation of the rotating part d is stopped, the fixing of the slide shaft e and the excavation pipe f is released, and the slide shaft f is moved upward. Then, the operation of fixing the excavating pipe f again has to be repeated, so that much time and labor are expended. Work efficiency is very poor,
In addition, there is a problem that the work of adding the excavation pipe is extremely troublesome. Therefore, an object of the present invention is to provide a boring apparatus capable of continuously performing a boring operation in order to solve the above problems.

[0004]

The above object of the present invention can be achieved by an apparatus having the following configuration. That is, the gist is that at least three sections are provided between the upper fixed frame portion and the lower fixed frame portion.
More than one rod is erected, a slide plate portion is inserted through the rod, and a hydraulic motor is used to allow the rod to move up and down. At the substantially center, a rotating portion through which a drilling pipe is freely inserted is provided. Is rotatable by a drive motor, and a mechanism for fixing the base end of the excavation pipe by a fastening portion is provided.A rod between the lower fixed frame portion and the slide plate portion is vertically movable by a drive motor. A hydraulic cylinder is provided in the pipe joining frame, and the waiting excavation pipe is moved to a fixed position by a gripping portion attached to the tip of the piston rod of the hydraulic cylinder. A boring apparatus characterized in that the boring apparatus is configured to perform the above-mentioned operations.

[0005]

In the boring apparatus of the present invention, as shown in FIG. 4, when the excavation of the excavation pipe A is completed by the lowering of the slide plate section 4 and the rotation of the rotating section 10, the next excavation pipe A is removed. When joining, as shown in FIG. 5, the connection between the rotating portion 10 and the excavation pipe A is released, the slide plate portion 4 is moved upward, and the pipe joining frame portion 12 is further moved to the fixed position. Up to The excavating pipe A in a standby state indicated by the imaginary line in the figure is gripped by the gripping portion 15 at the tip thereof by the expansion and contraction of the piston rod 14 of the hydraulic cylinder 13 and moved to a fixed position to join the pipes. is there. After the joining of the pipes is further completed, the base end of the pipe for excavation A is fixed to the rotating part 10 of the slide plate part 4, and the frame part 12 for pipe joining is lowered to lower the pipe A for excavation. The excavation is performed by lowering the slide plate portion 4 while moving. In the device of the present invention, the upper fixed frame 1
By assembling a scaffold upward, the excavation pipe A can be attached and detached by hanging the excavation pipe A from above. In this case, unlike the related art, there is no time and effort to rearward the equipment main body, and the working efficiency is greatly improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A boring apparatus according to the present invention will be described below in detail with reference to the drawings showing an embodiment thereof. FIG. 1 is an overall explanatory view showing one embodiment of the present invention.
The four rods 3 are erected between the lower fixed frame 2 and the lower fixed frame 2. The slide plate 4 is inserted into the rod 3 in a vertically movable manner, and the slide plate 4 is mounted on the rotary shaft of a hydraulic motor 5 provided on the upper fixed frame 1. The gear unit 6 and the gear unit 6 provided on the lower fixed frame unit 2 are connected by a chain 7, and one end of the chain 7 is connected and fixed to the slide plate unit 4, whereby the hydraulic motor is connected. The mechanism can be moved up and down by the driving torque of the motor 5.

At the approximate center of the slide plate portion 4, an insertion hole 8 through which the excavation pipe A can be inserted is provided. Further, as shown in FIG. To
Rotating part 10 rotatable by bearing member C
Is mounted, and can be driven and rotated by a driving motor 9. Further, this rotating part 10 is
1 connects and fixes the base end of the excavation pipe A, and the rotation of the rotary unit 10 causes the excavation pipe A to be driven and rotated.

Next, as shown in FIG. 3, the lower fixed frame 2
A pipe joint frame 12 is inserted between the rod 3 and the slide plate 4, and a mechanism capable of moving up and down by a hydraulic motor 5 and a chain 7 like the slide plate 4. A hydraulic cylinder 13 is provided on the pipe joining frame 12 and a grip 15 is attached to the tip of a piston rod 14 of the hydraulic cylinder 13 to make the mechanism movable back and forth. . A pipe lock device 16 is provided at the center of the upper fixed frame 1 and the lower fixed frame 2 so that the pipe can be freely penetrated. If necessary, the pipe is locked. The mechanism can be used to attach and detach pipes.

[0009]

As described above, according to the apparatus of the present invention, a series of excavating operations can be continuously performed, so that the efficiency of the operation is extremely improved. This makes it possible to easily perform this.
