[

When the first drive motor 11 is driven, the first shaft 12 rotates and the pinion gear 13 coupled to one end of the first shaft 12 rotates together.

The minute sandstone 30 is provided with a rack 32 meshing with the pinion gear 13 so that the minute dispersing arm 30 moves forward or backward as the pinion gear 13 rotates. The forward movement means that the injector unit 40 coupled to one end of the spray gun 30 moves in the direction away from the central axis, i.e., the first shaft 12, Is meant to move toward the central axis.

In the case of the minute rocks 30 illustrated in FIG. 1, when the pinion gear 13 rotates clockwise, it is moved forward, and when the pinion gear 13 rotates counterclockwise, it moves backward. This is only an example, and may be reversed depending on the position of the rack 32 formed in the spray gun 30.

In FIG. 1, four dispersing rocks 30 are provided and are arranged at intervals of 90 degrees around the center shaft (first shaft 12). However, this is also an example only, and it is also possible that the two dispersing rocks 30 are arranged at intervals of 180 degrees or the three dispersing rocks 30 are arranged at intervals of 120 degrees.

That is, when the number of the dispersing rocks 30 is N, the N dispersed rocks 30 may be arranged at intervals of 360 / N degrees (占) around the central axis.

At the end of the minute sandstone 30, an injector unit 40 for injecting a material for maintenance of the outer diameter and the inner diameter of the pipes constituting the drilling drill is coupled.

Maintenance work on the outer diameter and inner diameter of the pipes constituting the drill drill includes cleaning work, lubrication work, and the like. Accordingly, the maintenance material may include at least one of a compressed gas (air) for cleaning, and a lubricant for lubrication.

Or may share the compressed gas storage part 52 and the lubricant storage part 51 according to the embodiment (see FIG. 2 (b)).

When the injector units 40 are arranged at the same height, the maintenance efficiency becomes the highest. However, since the N dispersed rocks 30 cross each other and are engaged with the pinion gear 13, a height difference is generated by the thickness of the dispersing rock 30.

Therefore, in the case of the injector unit 40 located at the lower distributor arm 30, the installation height is raised by the thickness of the spray gun 30, so that the injector units 40 are positioned at the same height with each other, You can increase it.

The second driving unit 20 includes a second driving motor 21, a second shaft 22 rotated by the second driving motor 21, a second gear 23 provided on the second shaft 22, . The second gear 23 meshes with the first gear 15 formed on the outer peripheral surface of the base plate 14.

The image pickup unit 120 is provided with a camera both inside and outside so that the outside camera operates when cleaning the inside diameter of the pipe and the inside camera can be operated when cleaning the outside diameter of the pipe.

The control unit 60 controls each component so that the maintenance work is performed in the order of cleaning and lubrication.

For this, the control unit 60 controls the amount of rotation of the first driving unit 10 in accordance with the end property and diameter of the pipe to be maintained (step S310).

Thereafter, control is performed so that the rotation of the second driving unit 20 and the injection operation of the injector unit 40 are performed simultaneously or in an arbitrary order (step S320).

At this time, the injection operation of the injector unit 40 can be divided into a cleaning operation and a lubrication operation.

First, the injection nozzle connected to the compressed gas storage unit is controlled by the injector unit 40 so that compressed gas is injected to remove foreign substances adhering to the inner or outer diameter of the pipe, thereby performing cleaning (step S322).

Then, the image of the end of the pipe picked up by the image pickup unit 120 is analyzed (step S324). It is determined whether or not the cleaning operation is completed (step S326). For example, the determination of whether or not the cleaning operation is completed can be performed by comparing and analyzing an image of a pipe end of a clean state, which has been previously stored in the storage unit, and a currently captured end image, and counting the pixel difference In addition, various image analysis methods can be applied.
