Exterior Wall Climbing Device with Docking Mechanism for Lift and Horizontal Movement Units

This technology is a climbing device that moves along vertical and horizontal rails installed on building exteriors. It performs vertical and horizontal movement through a docking mechanism between a lift unit and a horizontal movement unit, with a docking guide unit ensuring smooth engagement.

Maintaining the exterior of skyscrapers poses risks of worker falls, inefficiencies in manual labor, and inconsistent quality. Existing suction-based robots suffer from poor adaptability to building shapes and difficulties in preventing falls during operational errors.

This technology proposes a system that separates the lift unit, which travels on vertical rails, from the horizontal movement unit, which travels on horizontal rails. It optimizes the coupling mechanism using a docking guide equipped with conveyor belts and rollers, and ensures stability during ascent and descent through inchworm-style propulsion. It can be applied to exterior cleaning and inspection of skyscrapers, fundamentally eliminating industrial accident risks by replacing manual high-altitude work.

Key Features:

• A lift unit capable of vertical movement along a pair of vertical rails installed on the building exterior
• A horizontal movement unit that travels along a pair of horizontal rails
• A configuration that moves between the docking entry position and the docking completion position to dock with the lift unit
• A docking guide unit that employs a structure of multiple transport rollers and conveyor belts to guide the docking process
