[0002]

2. Description of the Related Art Conventionally, a method of constructing a legal framework has been widely used for the purpose of preventing slope collapse and protecting the surface layer. Further, in order to stabilize the slope, it is often practiced to penetrate the intersection of the slopes of this kind and insert a reinforcing bar such as a rock bolt into the ground.

Conventionally, the drilling for this kind of rock bolt has often been carried out manually by a hand-held drilling machine, but recently, a drilling machine is mounted on the tip of a boom such as a rough terrain crane or a crane. It is mechanized by hanging a drilling machine from the tip of the boom with a wire. In addition, a method of drilling a guide cell and a simple drilling device simply equipped with a drilling machine capable of advancing and retreating on the guide cell by arranging wires or the like from a plurality of directions and standing on the slope Has also been done.

[0004]

However, all of these drilling methods have the following problems. When drilling, the drilling machine could not be properly fixed, and the drilling efficiency was reduced, and even if mechanized, the workability was not significantly improved.

Further, a hydraulically driven chuck member is attached to the tip of the boring machine, and the chuck frame is held by the chuck member.
There is also a method of fixing the hole drilling device, but in this case also, the chuck frame damages the method frame, and a hydraulic mechanism or the like is required, which complicates the structure of the hole drilling machine itself and increases the weight. There were various problems such as reduced portability at the factory.

The present invention has been made in view of the above problems, and an object of the present invention is to relieve a worker from labor and labor due to human power, reduce dangerous work, and
