The pretreatment work module 200 according to the present invention configured as described above is installed to be located in front of the robot by being fastened to the aerial work robot 100 as shown in FIG. 5.

The aerial work robot 100 is autonomously moved to the working position to perform a pre-processing polishing operation in a state attached to the hull shell plate by the operation of the vacuum pad. In the drawings, respective connecting cables, pneumatic hoses, dust suction hoses, and the like are omitted. The aerial work robot 100 has been described in detail as a prior art, so the detailed description is not given in the embodiments of the present invention.

The pretreatment work module 200 is mounted on the robot 100 as described above to perform the pretreatment work. The present invention controls the polishing tool raising / lowering device 230 by remote control, and the pneumatic cylinder 231. Pneumatic control of the pneumatic shaft 232 is forward / backward operation, the rotary link 234 connected to the pneumatic shaft 232 is rotated to rotate the angle of the clamp 235. Therefore, the polishing module 220 itself fixed to the clamp 235 is raised or lowered as shown in FIG. 6 to become a work waiting state or a work loading state.

When the motor 223 is operated, the rotational force of the motor fleece 223a rotates the polishing tool fleece 224 through the belt 225 to rotate the polishing tool rotation shaft 226, and the rotation of the rotation shaft 226. When the polishing tool 240 is rotated by the control to the tool lowered state to perform the polishing operation.

At this time, the present invention by placing the abrasive (sandpaper) 242 inclined at regular intervals inclined to rotate while pressing a tool produced by stacking a number of sheets on the work target surface to perform the polishing operation of the height. That is, the abrasive 242 is overlapped with a plurality of steps, and the step is overlapped, and the radially, that is, mounted on the tool drum 241 in the form of a propeller, the abrasive 242 is pressed on the work surface during rotation to form a scratch pattern, so It is possible to work on the object to be polished.

In addition, the present invention devised an apparatus to replace the abrasive because it is consumable and has a structure that can replace the propeller type abrasive 242 individually or replace the cylindrical abrasive tool 240 itself. Here, the replacement of the abrasive 242 may include a coupling structure in the form of a clamp on the tool drum 241, and may be configured to be fixed by tightening with a screw, and to replace and replace it.

In addition, the present invention can adjust the pretreatment polishing operation pattern, which is a controller (ground controller; not shown in the drawing) because the pretreatment operation pattern and the operation results are changed by the tool rotation speed and the pressing force of the polishing tool 240. In the tool rotational speed control is possible, the pretreatment work module 200 is configured to enable the operator to adjust the degree of pressing. The degree of depression is controlled by adjusting the pneumatic pressure through the tool raising / lowering device 230 to adjust the general degree of pressing by adjusting the angle to the whole of the polishing module 220, the fine adjustment is a knob ( When the 233 is adjusted by tightening or loosening, the pneumatic shaft 232 is finely adjusted forward / backward according to the degree of tightening or loosening, so that the degree of pressing can be adjusted, thereby enabling the working pattern to be adjusted. It is also possible to form a constant work pattern even when the pretreated abrasive is consumed by the work through the knob adjustment.
The tool raising / lowering device 230 branches the compressed air (air) hose supplied to the vacuum pump 33 of FIG. 2 of the present invention to provide a speed control function mounted on the double-acting pneumatic cylinder 231 of FIG. 4. The branch is connected to the one-touch fitting and the solenoid valve of the vacuum pump is turned on / off. When the operator wants to control the solenoid valve to advance the pneumatic shaft 232 of the pneumatic cylinder 231 to raise / lower the pre-processing abrasive tool. At this time, the pressing angle adjusting knob 233 adjusts the pressing degree of the abrasive to meet the required polishing performance (profile) and to adjust the degree of pressing finely when the abrasive is worn out and used to adjust the pressing angle adjusting knob 233. Will be used. The pressing angle adjustment knob 233 is configured in the form of a female screw, such as a nut therein, as shown in Figure 4 of the present invention, and the left end of the pneumatic shaft 232 is configured in the male screw type, such as bolts are fastened to each other. To adjust the degree of pressing of the abrasive, when the angle of rotation adjusting knob 233 is turned clockwise, the shaft length (stroke) of the pneumatic shaft 232 is reduced, so that the abrasive is less pressed when the tool is lowered, and the knob 233 is half pressed. When rotated in the clockwise direction, the shaft length (stroke) of the pneumatic shaft 232 increases, so that the abrasive is further pressed by the length of the extended shaft when the tool is lowered, thereby enabling fine adjustment of the pressing angle of the abrasive.

The raising / lowering device 230 of the polishing module 220 is configured to have a tool raising / lowering function of the polishing module 220 so as to selectively use a work module when moving to a pretreatment work and a corresponding work site. This is as shown in Figure 6, to control the rising / falling of the polishing module 220 by pneumatic control.

In addition, the present invention is provided with a dust scattering prevention and recovery device, and cover 250 for preventing the scattering of dust and foreign matter generated during the pre-treatment polishing operation. There is an inlet 251 for dust collection on the cover 250 is configured to recover the dust generated through the ground dust collector and the recovery hose.

On the other hand, the brush 252 is attached to the lower portion of the cover 250 so as to correspond to the non-uniform working surface.

Since there is no need for aerial platform to perform work in aerial or narrow space, it can protect workers from musculoskeletal diseases and pneumoconiosis caused by falling safety accidents and manual operation of workers, and it is operated by remotely controlled robots Because it is accessible from a long distance. In addition, the productivity is increased compared to the existing manual work, and the standardization of the pretreatment work quality is possible.
