In this way, the vertical frame 1a and the horizontal frame 1b are configured to function as guide rails for the horizontal rack 6 and vertical rack 7.

A movable box 10 is provided at the intersection of the horizontal rack 6 and the vertical rack 7 so as to be movable vertically and horizontally as the racks 6 and 7 move.

Inside this box 10, there is a first pinion gear 11 that meshes with the horizontal rack 6 and a vertical rack 7.
A second pinion gear 12 that meshes with the second pinion gear 12 is disposed.

These pinion gears 11 and 12 are rotated by rotary drive motors 13 and 14 provided at the rear, respectively. In addition, these motors 13,
A rotation shaft 14 projects in front of each pinion gear 11, 12, and an encoder 1 is installed at the projecting end to detect the amount of rotation of each motor 13, 14.
5 and 16 are fixed.

Among the above, the horizontal rack 6, the first pinion gear 11 and the motor 13 serve as the horizontal movement mechanism 17, and the vertical rack 7, the second pinion gear 12
and a motor 14 are configured as a vertical movement mechanism 18.

Cable 13 connected to motors 13 and 14
Cables 15a and 16a connected to encoders 15 and 16 are combined into one cable 19 and sent to a control unit 21 provided in a gondola 20 fixed to the lower horizontal frame 1b. It is connected.

Furthermore, a pair of guide rollers 22 are provided approximately in the center of each of the upper, lower, left, and right inner surfaces of the box 10 to sandwich the horizontal and vertical racks 6 and 7, respectively. The guide rollers 22 restrict the position of the moving box 10 so that it is centered at the intersection of the horizontal and vertical racks 6 and 7.

A work unit 23 that automatically performs construction, maintenance, cleaning, etc. of the outer wall of a building is removably fixed to the front of the movable box 10.

The movable box 10 configured in this manner moves the vertical rack 7 inside the frame 1 by driving the motor 13 and rotating the first pinion gear 11.
It is designed to move from side to side as well. Further, by driving the motor 14 and rotating the second pinion gear 12, the frame 1 is moved up and down together with the horizontal rack 6.

Therefore, if such vertical and horizontal movements are combined and controlled by the control unit 21, the moving box 10 can be moved to an arbitrary position within the frame 1.
