This technology is an exterior wall climbing device that includes a mechanical docking guide and a hook-based docking stabilization assembly to ensure stable coupling and decoupling between a lift unit moving along vertical rails installed on a building's exterior and a horizontal movement unit moving along horizontal rails.
Existing rope or gondola methods for exterior building maintenance pose safety risks, and robots often experience incomplete docking or detachment at the intersections of horizontal and vertical rails due to a loss of wheel traction.
This technology proposes a method that forces the seating and detachment of units using a docking stabilization assembly composed of a hook member, a hook hole, and a screw drive unit, rather than relying on the horizontal movement unit's own propulsion. It can be applied to exterior maintenance robots to reliably prevent falls caused by docking failures at rail intersections.
This invention was developed with support from the Korea Agency for Infrastructure Technology Advancement for the development of an intelligent robot system for the maintenance of high-rise building exteriors.
