2. Description of the Related Art For example, when a gas or water pipe is buried in the ground, there is a method of digging an excavation groove over the entire length of the pipe. However, this method has a problem that the excavation cost is extremely high. So, for example, as shown in FIG.
Drilling grooves 101 at two locations corresponding to the beginning and end of the conduit
A method called a non-cutting method has been proposed in which a self-propelled drilling machine 103 forms a drilling 104 from the starting excavation groove 101 to the end side excavation groove 102 by excavating 102.

The drilling machine 103 includes a pneumatic type using compressed air as a driving fluid and a hydraulic type using pressurized oil as a driving fluid. This is advantageous because the length of the excavation grooves 101 and 102 can be reduced. This drilling machine 103 is prevented from moving backward in the soil by receiving the reaction force at the time of propulsion by the soil, but at the start of drilling, it penetrates in the drilling groove 101 on the starting end side (piercing direction). Starting device 105 that prevents backward movement and starts underground
Must be used.

As the starting device 105, for example,
There is a so-called starter assisting device for a drilling device disclosed in JP-A-56-11039, and a so-called mounting device disclosed in JP-B-54-18486. The drilling machine 103 that has started in the soil may have its drilling direction interrupted or bend in the soil due to rocks in the soil, etc. As shown, a wire 106 is connected to the rear end of the drilling machine 103 in advance. In such a case, instead of the starting device 105, the winch 107 grounded in the excavation groove 101 on the starting end side
By winding the drill 106, the drilling machine 103
Removed to 1 Also, some wire guides are arranged in place of the starting device 105 in the excavation groove 101 on the starting end side, and the drill 106 is pulled out into the excavation groove 101 on the starting end side by winding the wire 106 with the winch 107 on the ground. Sometimes.

[0005]

As described above, the drilling machine 10
When the operation shifts from the drilling operation by 3 to the removal operation of the drilling machine, the starting device 105 in the excavation groove 101 is removed and the winch 10 is removed.
7 in the ditch 101, remove the starting device 105 in the ditch 101, and attach several wire guides to the ditch 10.
In addition to installing the winch 107 on the ground, it is necessary to perform an operation of installing the winch 107 on the ground, and there is a problem that a great deal of labor and time is required to shift from the drilling operation to the drilling machine removal operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a self-propelled drilling machine starting device capable of shifting from drilling to drilling machine removal in a short time in a simple operation. It is intended to provide.

I have. Handles 9 for carrying the starting device are provided on the left and right sides of the grounding frame 2. The starting guide frame 4 is arranged above the grounding frame 2. The starting guide frame 4 can be fixed to the grounding frame 2. However, in order to finely adjust the penetration direction of the drilling machine 3, the starting guide frame 4 has a horizontal axis and a vertical axis with respect to the grounding frame 2. It is supported on the grounding frame 2 so as to be rotatable around.

The structure in which the starting guide frame 4 is supported on the grounding frame 2 so as to be rotatable around the horizontal axis and the vertical axis is not particularly limited. For example, the rotary table is rotatable around the vertical axis on the grounding frame 2. May be supported, and the start guide frame 4 may be supported on the rotary table so as to be rotatable around the horizontal axis. However, in this embodiment, in order to reduce the movement of the tip of the drilling machine 3 when the penetration direction of the drilling machine 3 is adjusted and to reduce the error of the drilling position of the drilling machine 3, the front end of the starting guide frame 4 is required. For example, it is connected to the grounding frame 2 so as to be rotatable around a horizontal axis and a vertical axis by a ball joint 10, and an intermediate portion (or a rear end) of the starting guide frame 4 in the front-rear direction can be moved up and down by an adjusting mechanism 11. And it is supported by the grounding frame 2 so as to be movable in the left-right direction.

The front and rear length of the starting guide frame 4 may be longer than necessary to guide the propulsion of the drilling machine 3 in the penetration direction. In order to prevent the boring machine 3 from being lifted from the starting guide frame 4 by the front and rear holding frames 5 and 6 until the propulsion becomes possible, the front and rear length of the starting guide frame 4 is set to about 50 times the entire length of the boring machine 3.
Over a percent.

The adjusting mechanism 11 can move up and down the rear end of the starting guide frame 4 and can move in the left-right direction.
In this embodiment, a guide roller 31 for guiding the wire 26 of the punching machine removing device 25 is attached to the rear end of the starting guide frame 4 as described later. For this purpose, the intermediate portion of the start guide frame 4 in the front-rear direction is supported on the grounding frame 2 so as to be able to move up and down and move in the left-right direction.

That is, in this embodiment, a pair of left and right horizontal adjustment screws 13 are operated by operating a pair of left and right vertical adjustment screws 12 to raise and lower an intermediate portion of the starting guide frame 4 in the front-rear direction. An intermediate portion of the starting guide frame 4 in the front-rear direction is moved left and right. Of the holding frames 5 and 6,
The front holding frame 5 is connected to the starting guide frame 4 via the hinge 14.
The start guide frame 4 can be opened and closed between an open position where the upper side of the vehicle is opened and a closed position that covers the upper side of the start guide frame 4.
Linked to Also, this holding frame 5 is bolted in the closed position.
15 allows it to be fixed to the starting guide frame 4.

The rear holding frame 6 is attached to the starting guide frame 4 by a thumb screw 23 from above the drilling machine 3. The pressing frame 6 is formed integrally with a cover 24 that covers the outside of the spring 16 of the pressing force applying means 7 in the left-right direction. The pushing force applying means 7 includes a spring 16, a thumb screw 17 for engaging one end of the spring 16 with the starting guide frame 4, a hook 18 and a pin 19 connected to the other end of the spring 16, and another Pin 20
And a spring receiver 21 attached to the rear end of the drilling machine 3 placed on the starting guide frame 4.

When drilling work is performed using this starting device, for example, the grounding frame 2 is roughly aligned in the drilling direction and placed on the ground, for example, the bottom surface of an excavation groove. An anchor 1 is driven into the ground to fix the grounding frame 2 to the ground. Thereafter, the bolts 15 are loosened to open the holding frame 5, the holding frame 6 is removed, the drilling machine 3 is placed on the starting guide frame 4, the holding frame 5 is closed, and the holding frame 5 is bolted.
At 15, it is fixed to the starting guide frame 4, and the boring machine 3 is brought into tight contact with the starting guide frame 4 and the holding frame 5. After that, one end of the spring 16 is engaged with the thumb screw 17 screwed to the starting guide frame 4, and the spring receiver 21 is put on the rear end of the drilling machine 3. The hook 18 is engaged with the pin 20 provided on the spring receiver 21, the spring 16 is mounted between the starting guide frame 4 and the spring receiver 21, and the holding frame 6 is lightly attached to the starting guide frame 4 by the thumb screw 23. .

In this state, the adjusting mechanism 11 is operated to finely adjust the elevation angle or depression angle in the penetration direction and the azimuth on the plane, and then the two hydraulic oil hoses connected to the rear end of the drilling machine 3 are connected. The pressurized oil is supplied to and discharged from the drilling machine 3 via the drilling machine 3, and the drilling machine 3 is operated.
At this time, the screw 15 is loosened to a close contact state without pressing force. When the rear end of the drilling machine 3 passes through the rear end of the starting guide frame 4, the operation of the drilling machine 3 is temporarily stopped because the drilling machine 3 is in the soil to such an extent that it can be self-propelled. The frame 6 and the pushing force applying means 7 are disassembled and removed, thereby releasing the backward movement preventing function of the pushing force applying means 7.
Further, the boring machine removing device 25 shown in FIG. 1 is assembled to the grounding frame 2, and the wire 26 of the boring machine removing device 25 is connected to the rear end of the boring machine 3. At this time, the boring machine removing device 25 may be securely fixed to the grounding frame 2, but at this time, it is not necessary to securely fix the boring machine removing device 25 to the grounding frame 2.

As shown in FIGS. 1 to 3, a pin 28 for engaging the frame 27 of the punching machine removing device 25 and a bolt 29 for fixing the frame 27 to the grounding frame are screwed into the rear portion of the grounding frame 2. A screw hole 30 is formed. A guide roller 31 for guiding the wire 26 is fixed to the rear part of the start guide frame 4 so as to be disassembled. A manual winch 32 for winding the wire 26 is supported at the lower part of the frame 27 of the punching and removing device 25. The upper end of the frame 27 and the soil end face 33 are provided as necessary.
And a support fitting device 34 is provided. The support fitting device 34 includes a mounting pin 35 fixed to the upper end of the frame 27.
And a support fitting main body 36 externally inserted into the mounting pin 35, and a contact fitting 37 abutting on the soil end face 33 and screwed to the support fitting main body 36. Handle 38 is provided.

After the drilling machine 3 is blocked by strong rocks or the like, the drilling is bent, or the drilling is completed, the bolts of the drilling machine removing device 25 are not used until the drilling machine removing operation is started.
Tighten 29 to securely fix the boring machine removal device 25 to the grounding frame 2, and further install the guide roller 31 at the rear of the starting guide frame 4 as necessary, and then operate the winch 32 to wind the wire 26. Take the drilling machine 3 from the drilling 39 and start the guide frame 4
Remove on top.

According to the above-described operation procedure, the drilling machine 3 can be mounted on the starting device by lowering the drilling machine 3 from above with the front holding frame 5 opened and the rear holding frame 6 removed. In addition, there is no need for a space for an operator to press the drilling machine 3 behind the starting device. For example, when the starting device is installed at the bottom of the cut groove to perform the drilling operation, the total length of the drilling machine 3 and the drilling machine 3 And the left and right width of the start and the left and right sides of the launching device and the left and right sides of the launching device on one side of the launching device. Excavation of a narrow open groove is sufficient, and the excavation cost can be reduced.

The drilling machine 3 can be mounted on the starting device by opening the front holding frame 5 and lowering the drilling machine 3 from above with the rear holding frame 6 removed.
The boring machine 3 can be mounted on the starting device in a short time with a simple mounting operation. In addition, when the penetration direction of the drilling machine 3 is finely adjusted, the amount of movement of the tip of the drilling machine 3 is small, so that the drilling machine 3 can penetrate the soil from an accurate penetration position.

When the operation of the drilling machine 3 starts, the spring 16
Positively urges the drilling machine 3 in the drilling direction, so that the biasing force of the spring 16 opposes the reaction force at the time of propulsion of the drilling machine 3 and prevents the drilling machine 3 from moving backward. Wear of the punch 3 and the starting device, particularly the starting guide frame 4 and the front and rear holding frames 5 and 6 of the starting device is significantly reduced, and the durability of the drill 3 and the starting device is enhanced.

Further, since the drilling machine 3 is pushed into the soil by the biasing force of the spring 16, the drilling machine 3 enters the soil in a short time and the biasing direction of the spring 16 is stable. There is no possibility that the penetration direction of the drill 3 will be disturbed, the drill 3 can be accurately penetrated in the penetration direction, and the operator does not need to receive the vibration of the drill 3. Further, when the drilling machine 3 is penetrated to the extent that it can be self-propelled into the soil, the rear holding frame 6 and the pushing force applying means 7 are removed, and the drilling machine removal device 25 is assembled to the grounding frame 2 of the starting device. When shifting from the drilling operation by the drilling machine 3 to the punching machine removing operation, only the operation of securely fixing the drilling machine removing device 25 to the grounding frame 2 by tightening the bolt 29 and the assembly of the guide roller 31 to the starting guide frame 4 are performed. Only needs to be done.

However, when assembling the boring machine removing device 25 to the grounding frame 2 of the starting device, if the bolt 29 is tightened to securely fix the boring machine removing device 25 to the grounding frame 2, the boring machine removal work is started from the boring work. The operation of tightening the bolt 29 is not required when shifting to. Therefore, in each of the above-described conventional examples, the entire starting device is removed when the operation shifts from the drilling operation to the drilling machine removal operation, and the drilling machine removal device and the wire guide are installed in the excavation groove. With a simple operation, the operation can be shifted from the drilling operation to the removal operation of the punch in a short time.

At the end of the boring machine removal operation, the boring machine 3 is pulled back onto the starting guide frame 4 and is held by the front holding frame 5 so as not to be lifted from the starting guide frame 4. 2 with the drilling machine removing device 25 assembled and the drilling machine 3 connected to the wire 26 of the drilling machine removing device 25 at a time, the starting device, the anchor 1, the drilling machine removing device 25 and the drilling machine 3 are removed from the cutting groove. For example, it can be lifted up using a backhoe, a crane mounted on a vehicle, or the like, so that the work of removing the drilling machine removal device 25 and the starting device can be performed easily and in a short time. Can be removed.

In the above embodiment, the starting guide frame of the starting device only needs to be configured so as to support the self-propelled drilling machine in a predetermined penetration direction. What is necessary is just to comprise so that the backing which supports the drilling machine supported by the frame so that it cannot go backwards can be prevented. Therefore, in each of the conventional examples described above, when the reverse prevention function of the reverse prevention means is released, the drilling machine that is mounted on the grounding frame and is launched into the soil from the starting guide frame through the drilling guide frame is mounted on the starting guide frame. It may be configured such that a punching machine removing device for removing is provided above. In the above embodiment, an electric winch may be used instead of the manual winch 32.

[0027]

As described above, according to the present invention, when the reverse prevention function of the reverse prevention means is released, the drill is mounted on the grounding frame and launched into the soil from the starting guide frame. Since the drilling machine is equipped with a punching machine removal device that removes the drilling machine from the drilling onto the starting guide frame, the reverse prevention function of the reverse movement prevention device is released without removing the entire starting device, and the drilling machine removal device is assembled on the installation frame. By attaching, it is possible to obtain an effect that the operation can be shifted from the drilling operation to the punching-out operation in a short time with a simple operation.
