Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for setting a guide shell of a crawler drill equipped with a rock drill at a position where maintenance is easy.

[0002]

2. Description of the Related Art Generally, in a crawler drill, a guide mounting for tilting and swinging is attached to the tip of a boom pivotally supported on a bogie so that the guide shell can be supported by the guide mounting. The guide shell was attached to the guide mounting so that the surface on which the rock drill was mounted was horizontal, with the guide shell horizontal.

However, in recent years, in order to improve the working environment, a crawler drill with a cabin has come to be used, and a guide mounted on the guide mounting so that the surface on which the rock drill is mounted is horizontal. In the shell, when the operator operates the drill, the drilling state cannot be sufficiently recognized from the inside of the cabin, and a problem often occurs during drilling. Therefore, the guide shell can be installed horizontally in the front-rear axis direction by tilting the surface on which the rock drill is mounted to the left and right to attach to the guide mounting, so that the operator can easily drill the rock drill from inside the cabin. Crawler drills that have been made visible have been used.

[0004]

The rock drill mounted on the guide shell requires maintenance work such as periodically exchanging consumables, and the rock drill is horizontal in the front-rear axis direction. The guide shell attached to the guide mounting so that the surface on which the is mounted is horizontal can be adjusted by tilting the boom's elevation and guide mounting so that the guide shell is level at the appropriate height in the front-rear axis direction. I was able to set it to a position that was easy to maintain.

However, in the guide shell mounted on the guide mounting by tilting the surface on which the rock drill is mounted horizontally in the front-rear axis direction, the guide shell is tilted by the elevation of the boom and the guide mounting. Even if the shell is horizontal at the proper height in the front-rear axis direction, the surface on which the rock drill is mounted is inclined to the left and right. If maintenance work is performed in this state, there is a great risk that the removed parts will fall, and heavy objects must be held in position until assembly and removal are completely completed, resulting in poor work efficiency.

The present invention solves such a problem in the crawler drill, and in order to improve the visibility of the operator, the surface on which the rock drill is mounted is tilted left and right in a state of being horizontal in the longitudinal axis direction. The guide shell attached to the guide mounting can be easily set to a position where the surface on which the rock drill is mounted is horizontal and maintenance is easy, and the maintenance position of the guide shell is set to improve the efficiency and safety of maintenance work. The purpose is to provide a method.

SUMMARY OF THE INVENTION According to the present invention, a guide mounting which is tiltable and swingable is attached to the tip of a boom pivotally supported on a bogie so that the boom can be swung up and down. In a crawler drill that supports a guide shell in which the surface on which the rock drill is mounted is tilted to the left and right in a horizontal state, the guide mounting is
It is configured to swing 0 °, and during maintenance work, swing the guide mounting 90 °, raise the boom to adjust the height of the guide shell, and tilt the guide mounting to rock the guide shell. The above problem is solved by making the surface on which is mounted horizontal.

[0008]

By operating the boom and the guide mounting as described above, the guide shell mounted on the guide mounting with the surface on which the rock drill is mounted is inclined to the left and right,
The surface on which the rock drill is mounted is horizontal and easily set to a position where maintenance is easy. If maintenance work is performed in this state, there is no risk of the removed parts falling, and heavy objects can be easily assembled and removed, and the efficiency and safety of maintenance work are improved.

1 is a side view of a crawler drill which is an embodiment of the present invention, FIG. 2 is a plan view showing the construction of a boom and guide mounting, and FIG. 3 is a side view showing the construction of a boom and guide mounting. Is. In the present embodiment, the crawler drill 1 has a boom base 13 pivotally mounted on a base 12 of a carriage 11 by a turning shaft 14, and a boom 15 is mounted on the boom base 13.
The lower end of the shaft is pivotally attached by the elevation shaft 16. Boom stand 1
3 between the base 3 and the base 3 and a hydraulic cylinder 17 for turning, and between the boom 15 and the boom base 13 a hydraulic cylinder 18 for elevation.
Is provided so that the boom 15 can be turned up and down.
A tilt arm 19 is pivotally attached to the tip of the boom 15 by a tilt arm shaft 20, and a tilt hydraulic cylinder 21 is provided between the boom and the boom 15 to enable tilting.
A swing arm 22 is pivotally attached to the tilt arm 19 by a swing arm shaft 23, and a swing hydraulic cylinder 24 is provided between the tilt arm 19 and the tilt arm 19, and the swing hydraulic cylinder 24 is provided at 30 ° in the clockwise direction and in the counterclockwise direction in FIG. It is possible to swing 90 degrees. A guide mounting 26 is supported on the swing arm 22, and a guide shell 29 is slidably supported by the guide mounting 26. A rock drill 30 is mounted on the guide shell 29 and can be moved in the front-rear direction by a feed cylinder (not shown). A rod 32 is attached to the drilling machine 30 and is hit and rotated to punch a rock of a face.

The crawler drill 1 is provided with a cabin 33, and the guide shell 29 is horizontal in the front-rear axis direction and the surface on which the rock drill 30 is mounted is tilted left and right so that the cabin 33 side becomes lower. Guide mounting 2
It is attached to 6. Therefore, as shown in FIG. 4, when the boom 15 is lifted and the tilt arm 19 is tilted downward so that the front end of the guide shell 29 is drilled toward the ground 34, as shown in FIG. From the inside of the cabin 33, the operator can easily visually recognize the drilling state of the rock drill 30.

As shown in FIG. 1, when the guide shell 29 is in a running posture in which the guide shell 29 is horizontal in the longitudinal axis direction, when the maintenance work is started, the guide mounting 26 is first performed.
Swing 90 degrees counterclockwise, then raise the boom 15 to adjust the guide shell 29 to a height that is easy to work with, and then tilt the guide mounting 26 to adjust the inclination, as shown in FIG. Thus, the surface of the guide shell 29 on which the rock drill 30 is mounted is made horizontal.

As shown in FIG. 4, when the guide shell 29 is in the downward drilling posture and the maintenance work is started, first, the tilt arm 19 is tilted upward to move the boom 15 downward to guide the guide shell. After returning 29 to the running posture in which it is horizontal in the longitudinal axis direction, it is set to the maintenance position in the same manner as described above. In this case, before returning the guide shell 29 to the running posture, the guide mounting 26 is first swung 90 ° counterclockwise, and then the boom 15 is moved.
7 and then the guide mounting 26 is tilted to adjust the inclination so that the surface of the guide shell 29 on which the rock drill 30 is mounted becomes horizontal as shown in FIG. You can also

If maintenance work is performed in this state,
There is no risk of the removed parts falling, and heavy objects can be easily assembled and removed, improving the efficiency and safety of maintenance work.

[0014]

As described above, according to the present invention,
In order to improve the operator's visibility, the guide shell attached to the guide mounting by tilting the surface on which the rock drill is mounted horizontally in the front-rear axis direction is the surface on which the rock drill is easily mounted. Can be set to a horizontal position for easy maintenance, and the efficiency and safety of maintenance work can be improved.
