Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drill machine used for boring work such as foundation work, boring work, or anchor work. In particular, the present invention relates to a stabilizer for a stationary medium-sized drill machine that can perform a drilling operation by appropriately setting the drilling angle within a range of approximately 90 ° from the horizontal direction to the vertical direction.

[0002]

[Prior Art]

 Generally, a stationary medium-sized drill machine is easier to disassemble, assemble, install, and has a lighter weight than a crawler machine, so it is highly portable and can be used for drilling work in tight spaces and high places. Has been evaluated as a suitable machine.

FIG. 3 and FIG. 4 are side views showing an outline of the structure of this stationary medium-sized drill machine. 3 shows a state in which the drilling angle is set in the horizontal direction, and FIG. 4 shows a state in which the drilling angle is set in the downward vertical direction. The structural characteristic of this stationary medium-duty drill machine is that a drifter 3 that gives a rotating force and a repeated impact force to a drill rod 2 via a lifting / lowering operation mechanism SM on a base frame 1 which is the base of the machine. A guide cell 4 equipped with the above is installed, and the guide cell can be set to 90 degrees downward from the horizontal state by operating the elevation operation mechanism SM.

That is, as shown in FIGS. 3 and 4, a base frame 1 is set on a drilling work site, and a guide cell 4 equipped with a drifter 3 is mounted on the base frame 1 via a depression / elevation operation mechanism SM. It is mounted, and the guide cell 4 is raised so as to match the predetermined drilling angle, and in that state the drill rod 2 is mounted on the drifter 3, and then the drifter 3 is operated to rotate the drill rod 2 repeatedly with the rotating force. In addition to giving a striking force, the drifter 3 itself is slid along the guide cell 4, that is, moved forward to perform an appropriate punching operation.

[0005]

[Problems to be solved by the device]

 By the way, the guide cell 4 equipped with the drifter 3 is set to a desired drilling angle within a range of 90 ° downward with respect to the horizontal state, that is, the state shown in FIG. 3 is raised to the state shown in FIG. When drilling is performed by setting the angle from the horizontal direction to the vertical direction, the guide cell 4 equipped with the drifter 3 is mounted on the base frame 1 which is the base of the machine as shown in FIG. It leans to one side of the frame. That is, the guide cell 4 is in a state of being erected along the right side of the base frame 1. As a result, a tipping moment is generated by the guide cell 4, and the work stability is impaired.

Conventionally, as a method for covering this drawback, a counterweight W as shown in FIG. 4 is mounted on the left side of the base frame 1, and the counterweight W is used for balancing to perform a punching operation. However, when the drilling site is a narrow place or a particularly high place, it takes a lot of time and labor to bring in the counterweight W and install it on the base frame 1 because a heavy machine such as a crane is required. There was a point. In other words, there is a problem that the setting work of the machine itself takes time and the mobility and workability as a medium-sized drill machine are impaired. Therefore, the present invention has as its object the provision of a drill machine that solves these problems, facilitates machine setting work, and incorporates a stabilizer for maintaining a safe drilling operation. It was invented.

[0007]

[Means for Solving the Problems]

 As a means for achieving the above-mentioned object, the present invention mounts a guide cell equipped with a drifter that gives a repetitive impact force to a drill rod on a base frame. Properly set up within a range of about 90 °, and a plurality of outriggers were pre-assembled to the base frame of the drill machine for drilling work so as to project freely in the outer peripheral direction of the base frame. Especially.

[0008]

[Action]

 Since the present invention is configured as described above, the tipping moment of the multiple outriggers that are freely attached to the base frame, which is the base, is applied before the guide cell is lifted and lowered. Place the outriggers that are located in the direction that the In this state, if the guide cell is lifted vertically, for example, and the vertical drilling operation is performed downward, the fall moment loaded on the base frame is alleviated. As a result, the stability of the machine itself is maintained.

[0009]

【Example】

 Further, the structure of the stabilizing device according to the present invention will be concretely described based on an embodiment shown in the drawings. FIG. 1 is a side view of a drill machine in which a guide cell 4 on a base frame 1 is installed in a vertically downward direction to perform a drilling operation, and FIG. 2 is a plan view thereof.

As shown in FIG. 2, in this embodiment, the base frame 1 which is the base of the machine is configured so that the planar shape is rectangular. Therefore, when the guide cell 4 is raised vertically downward, the guide cell 4 itself is set upside down along the right side of the rectangular base frame 1. Therefore, in this embodiment, two outriggers 10 as stabilizers are mounted along the right side of the base frame 1 so as to be projectable.

Specifically, as shown in FIG. 1 and FIG. 2, the base ends of the arm members 11 and 11 are connected to the right and left ends of the base frame 1 having a rectangular plan shape by connecting pins 12 and 12, respectively. Both the arm members 11 and 11 are rotatably extended horizontally in such a manner that the connecting pins 12 and 12 serve as fulcrums, and the outriggers 10 and 11 capable of adjusting the level are respectively provided at the tip ends of the arm members 11 and 11 which are rotatable. 10 was assembled. That is, when unnecessary, the arm members 11 and 11 are stored in such a manner that they are folded toward the base frame 1 side, respectively, and when necessary, the arm members 11 and 11 are swung to move the outriggers 10 and 10 in the outer peripheral direction of the base frame 1. It is configured to project.

In the embodiment, as described above, the two outriggers 10 and 10 are rotatably extended to both ends of the right side of the base frame 1 via the arm members 11 and 11. A guide member for accommodating the arm members 11 and 11 may be assembled to the unit 1, assembled by an insertion method, and pulled out and installed when necessary. The four outriggers 13 shown in FIGS. 1 and 2 are outriggers that are assembled to the existing base frame 1, and are always used when the base frame 1 is installed. An operation control panel for the drifter 3 and the like.

[0013]

[Effect of the device]

 As described above, the present invention has the following effects as compared with the conventional drill machine because the auxiliary outrigger that can freely project is attached to the base frame. (1) If the outrigger is installed so as to extend according to the setting of the drilling angle, that is, the elevation angle of the guide cell, the tipping moment generated in the drill machine itself can be alleviated. As a result, stable drilling work can be performed. (2) When unnecessary, that is, in the case of horizontal drilling work, it can be stored in the base frame side, so there is no hindrance to transportation or installation work. (3) Since the structure is extremely simple, it can be easily installed on an existing drill machine, and the function of the existing drill machine can be further expanded.
