Abstract

PURPOSE:To safely carry out a drilling work from the ground level without necessity that operators enter into a narrow shaft thrusting holes in a piping work of a non-opening process. CONSTITUTION:A gate-shaped base 9 is mounted on a carrier 18 provided with a traveling device 8 and a drilling device 4 with a guide shell 13 equipped with a drilling machine 12 in the space 10 of the gate-shaped base 9 is suspended so as to be vertically movable. The drilling equipment 1 is mobile in the state that the drilling device 4 is raised and contained in the space 10 of the gate- shaped base 9 and stops so as to ride on a shaft 3 thrusting holes. Then the drilling device 4 is lowered and fixed to the bottom 15 of shaft 3 where holes are excavated. After holes 17 for laying down pipes have been drilled to another shaft, the drilling device is raised and transferred by the mobile structure in the state contained in the space 10 of the gate-shaped base 9 to the next working site.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drilling machine for excavating underground in pipe work for laying pipes of small diameter such as gas and water in the ground.

[0002]

2. Description of the Related Art Generally, there are an open cutting method and a non-open cutting method as a pipe construction method for laying a pipe having a small diameter such as gas or water in the ground. In the excavation method, a construction machine such as a power shovel is used to excavate a groove for pipe laying from the surface of the earth. In the non-cutting method, a small-diameter pipe propelling machine is used to drill a pipe laying hole in the ground.

The excavation method is suitable when the excavation depth is shallow and does not obstruct the passage of roads. However, when the excavation depth becomes deep, soil excavation and regeneration processing are required, and the construction period becomes long, which leads to road passage. Inhibit. Therefore, the open cutting method using a small-diameter pipe propulsion device has come into wide use.

[0004]

However, since the conventional small-diameter pipe propulsion device is installed in the starting shaft in a stationary manner, the worker must enter the narrow starting shaft to perform the work. It was inconvenient and dangerous.
The present invention is to solve the above problems in a non-cutting construction method, in which the worker does not need to enter the narrow starting shaft to perform the work, and for the non-cutting construction method in which the work can be performed more safely. The object is to provide a drilling machine.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a carriage having a traveling device is provided with a gate type mount, and a gate type space of the mount is provided.
A drilling machine is constructed by suspending a drilling device including a drilling machine and a guide shell for mounting the drilling machine so that the drilling machine can be moved up and down.

[0006]

This drilling machine is self-propelled in a state where the drilling device is raised and stored in the gate-shaped space of the gantry, and stops across the starting shaft. Then, the drilling device is lowered and fixed to the bottom of the starting shaft to perform the drilling work. When the drilling work of the pipe laying hole to the reaching shaft is completed, the drilling device is raised and self-propelled in the state of being housed in the gantry space of the gantry, and then moved to the next work site.

Since the drilling operation is performed on the ground, it is not necessary for the operator to enter the narrow starting shaft to perform the work, and the work can be performed more safely.

1 is a side view of a drilling machine according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is an explanatory view of a drilling operation using this drilling machine. Is. Here, in the punching machine 1, a carriage 18 provided with a traveling device 8 is provided with a gate-shaped mount 9, and a gate-shaped space 10 is formed under the mount 9. Between the carriage 18 and the gantry 9 is provided a support means 19 having a shock absorbing function during traveling. Gate type space 10
A drilling device 4 including a drilling machine 12 and a guide shell 13 on which the drilling machine 12 is mounted is suspended from a frame 9 by a lifting device 5 so as to be lifted and lowered. A rod clamp 14 is provided at the front end of the guide shell 13 to fix the rod 7 when the rod 7 of the punch 12 is connected and disconnected. On the pedestal 9, a driving unit 16 for supplying a pressure liquid to driving units such as the traveling unit 8, the lifting unit 5, the drilling unit 4, and the like, and an operating unit 11 for operating each of the units are installed.

The drilling machine 1 is self-propelled in a state where the drilling device 4 is raised and stored in the gate-shaped space 10 of the mount 9.
It stops by straddling over a starting shaft 3 that has been excavated from the ground 2 in advance. Therefore, the elevating device is extended, the drilling device 4 is lowered and fixed to the starting shaft bottom 15, and the drilling work of the pipe laying hole 17 is performed. Drilling machine 12 along with the progress of drilling
Rods 7 are sequentially added and connected. At this time, the rear end of the rod 7 is fixed by the rod clamp 14 and the drilling machine 12
After the shank rod 20 is separated from the rod 7 by reversing, the drilling machine 12 is retracted to the rear end of the guide shell 13, the rod clamp 14 is loosened and removed from the rod 7, and the drilling device 4 is raised. The worker connects the additional rod 7 to the shank rod 20 on the ground, holds the front end of the rod 7 with the rod clamp 14, and again lowers the drilling device 4 to fix it to the starting shaft bottom 15. Then, the punching machine 12 is rotated in the forward direction to connect the next rod 7 to the previous rod 7, and the drilling work is continued.

When the drilling work of the pipe laying hole 17 up to the reaching shaft 6 is completed, the rod 7 is sequentially separated and recovered, and the drilling device 4 is raised and stored in the gate-shaped space 10 of the pedestal 9 by itself. And move to the next work site. For long-distance travel, they are transported by truck, but they can also be loaded on the loading platform easily by self-propelled. This drilling operation is
Since the work is performed on the ground, it is not necessary for the worker to enter the narrow start shaft 3 to perform the work, and the work can be performed more safely.

When the distance of the pipe laying hole 17 from the starting shaft 3 to the reaching shaft 6 is long, if a large number of rods 7 are stored and a rod magazine capable of automatically supplying when necessary is attached to the hole drilling device 4, the drilling device 4 is provided. It is efficient because the number of times of lifting and lowering of 4 can be reduced. After drilling work, pipe laying hole 17
In order to increase the diameter of the hole, a large diameter reamer can be attached to the rod tip at the reaching shaft 6 and the hole can be expanded while the drilling machine 12 is retracted.

The pipe can be laid in the pipe laying hole 17 while the pipe is connected to the tip of the rod on the side of the reaching shaft 6 and the drilling machine 12 is retracted.

[0013]

As described above, the drilling machine of the present invention does not need to excavate a groove for pipe laying from the surface of the earth, can carry out construction without obstructing the passage of roads, Since it does not enter the narrow starting shaft and works on the ground, it is labor-saving and highly safe. Further, since the drilling machine can be self-propelled, it is easy to move between work sites, and work efficiency is improved.
