DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope drilling apparatus and a method for fixing the same.

[0002]

2. Description of the Related Art In recent years, steep slopes that have deteriorated in recent years have been frequently subjected to mountain landslides due to surface separation, slippage, and collapse. In particular, steep slopes and long slopes in mountainous areas are the most dangerous, and safety measures are urgently needed for such places. Conventionally, in such places, protection work has been performed by pocket net works, rock fall protection fences, and reinforced concrete structures.

[0003]

However, the above-mentioned conventional protection works are all standby construction methods, and do not exert any resistance to the initial movement of the ground. In the combined construction method, a temporary scaffold or the like is required, so that there is a problem that a great deal of time and cost are required.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and its object is to always maintain a stable posture immediately in response to a construction site, and to surely maintain a steep slope. An object of the present invention is to provide a drilling machine to be fixed, a fixing method thereof, and a safest remote device.

[0005]

In order to achieve the above object, a slope drilling apparatus according to the present invention is arranged such that a drilling machine body can be tilted on a bottom plate of a rigid hanging metal via a hydraulic cylinder. And a winch mounted on both sides of the bottom of the hanging bracket, sandwiching the drilling machine main body, and a temporary anchor installed on a slope or slope at the tip of a wire wound on each winch. It is configured by attaching a hook to be locked.

Further, according to the method for fixing a slope drilling machine according to the present invention, the hook at the tip of the wire wound on a pair of winches disposed on the bottom of the hanging bracket with the drilling machine body interposed therebetween is used. , Is fixed to a temporary anchor installed on a slope or slope, and the respective winches are operated to tension the wires wound around the respective winches. Further, in the present invention, the operating device in the drilling machine main body is connected to a centralized hydraulic device installed on the bottom plate and a remote control plate connected thereto via a hydraulic hose, and is remotely controlled by the remote control plate. It is configured as follows.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings showing preferred embodiments of the present invention. A is a hanging bracket having a required rigidity, and is configured to be suspended by a swing crane B and moved to a required position. C
Is a drilling machine, and the hydraulic cylinders 1, 1
, Are tiltably supported. In the figure, reference numeral 2 denotes a hydraulic cylinder for moving a drilling machine (drifter) 3. Winches 4 are arranged on both sides of the drilling machine C on the hanging fitting 2, respectively, and each of the winches 4 is wound with a wire 6 having a hook 5 at the tip.

In the figure, 7 is a centralized hydraulic device, 8 is a remote control plate,
Reference numeral 9 denotes a hydraulic hose, which can be extended up to 30 m. When the drilling device is fixed to the sill D constructed on the slope, the temporary anchor 1 installed on the slope is used.
0, the tip hook 5 of the wire 6 is locked, and by operating each of the winches 4, the wire 6 wound around each of the winches 4 is tensioned, so that the operation can be performed easily and securely. Each wire 6 corresponds to a horizontal reaction force at the time of drilling.

Although the center of gravity of the drilling machine changes with the movement of the drilling machine C, the inclination angle of the drilling machine is adjusted by operating the hydraulic cylinder 1 so that the drilling machine is in a stable posture. Is adjusted so as to hold. Each of the above operations is performed by remote control using the remote control plate 8.

[0010]

According to the present invention, as described above, the drilling machine body is tiltably supported via the hydraulic cylinder on the base of the rigid hanging fitting, so that the drilling operation can be performed with progress. By operating the hydraulic cylinder in response to a change in the position of the center of gravity of the drilling machine, the drilling machine can always be kept in a stable state.

In addition, a winch is mounted on both sides of the bottom of the suspending fitting with respect to the drilling machine main body, and is engaged with a temporary anchor installed on a legal frame or ground at the tip of a wire wound on the winch. By providing the hook, the drilling device can be easily fixed to the slope and the slope structure, and the workability can be improved and the construction cost can be reduced without requiring a temporary scaffold as in the conventional case. Things.

According to the invention of claim 2, as described above,
By operating winches arranged on both sides of the drilling machine main body on the bottom of the suspension fitting, the wire with the tip hook hooked to the temporary anchor of the slope or the slope structure is tightened to cut the hole. The boring machine body can be easily and securely fixed to a slope or a slope structure. Also, the horizontal reaction force on the slope is controlled by the tension of the wire, so that the drilling machine can be securely fixed.

According to the invention of claim 3, as described above,
The operating device of the drilling machine main body installed on the bottom plate of the hanging bracket is remotely controlled by a centralized hydraulic device installed on the bottom plate, and a remote control plate connected thereto via a hydraulic hose, and The safety of the drilling device can be improved in combination with extending the hydraulic hose to a safe place.
