The repair by the outer wall surface repair automation system is performed by removing the deteriorated coating film on the outer wall surface 2a by the wall surface coating film removing device 501, removing the wall surface coating film removing device 501, and mounting the coating device 601 to remove the deteriorated coating film. The outer wall surface 2a is painted, but the present invention is not limited to this, and only the removed coating film may be removed or only the coating may be performed.
[0080]
In this embodiment, the wall surface coating film removing device 501, the coating device 601, and the moving device 6 are small and light, and can be transported by two people. For example, the wall coating film removing device 501, the coating device 601, and the moving device 6 can be transported by two people. There is no need for cranes and other equipment to transport to the bottom.
[0081]
In addition, the moving device 6 is also used as the wall surface coating film removing device 501 and the coating device 601, thereby reducing the number of devices constituting the system and replacing the coating work required when switching from the coating film peeling operation to the painting operation. Can be reduced.
[0082]
In the outer wall surface repair device 3 of this embodiment, the left and right suspension arms 26 are individually moved by an actuator 24 for peeling adjustment, and the distance between the distal end portion 26a (wire suspension point) of the suspension arm 26 and the outer wall surface 2a is changed. Thus, it is possible to adjust the pressing force to the outer wall surface 2a of the repairing device 5 suspended downward. For example, the outer wall surface 2a and the tip of the suspension arm 26 according to the height at which the wall surface coating film removing device 501 is lifted. By adjusting the separation of the portion 26a, the pressing force due to its own weight can be maintained in an appropriate range. Further, in the case of the painting apparatus 601, the position where the contact pressure of the painting roller 611 is optimal can be adjusted and maintained by adjusting the separation between the outer wall surface 2a and the tip end portion 26a of the suspension arm 26.
[0083]
Further, by individually operating the left and right separation adjustment actuators 24, the repair device 5 can be suspended while avoiding obstacles protruding on the wall surface such as the stairs 14 for raising and lowering. In this manner, by using the suspension arm 26, it is possible to flexibly cope with changes in the work status of the wall surface coating film removing device 501 and the coating device 601, and the refilling operation accompanying the movement of the suspension carriage 20 is easy.
[0084]
Further, the lower end of the suspension wire 40 is tensioned by the wire tension unit 30 installed immediately below the tower tanks 2, and the distance between the wall surface coating film removing device 501 and the coating device 601 and the outer wall surface 2a is kept constant. It prevents shaking and stabilizes. In addition, a commercially available spring balancer is used for the tension device 34 that tensions the suspension wire 40, and since it is small and simple in structure, it can be easily applied to the towers 2 having a narrow space immediately below the wall surface. . The frame material constituting the wire tension unit 30 is highly practical because it uses a temporary material that can be assembled and disassembled.
