Docking device

Docking device for securing maintenance equipment using a 3-point docking pin and hook interlocking system

This technology is a multi-docking system designed to securely fasten maintenance equipment to the horizontal movement module of an exterior wall climbing device by mechanically coupling docking pins located on the top, bottom, and sides of the maintenance equipment body with the docking unit inside the climbing device.

When performing exterior wall maintenance on high-rise buildings, there is a risk of worker falls. Existing methods for attaching cleaning tools often struggle to maintain stable fixation during movement, leading to a high risk of secondary accidents caused by falling equipment.

This technology proposes a method that places 3-point docking pins on the top, bottom, and sides of the maintenance equipment body and interlocks a hook-shaped docking pin catch with a docking hook inside the horizontal movement module to physically prevent the pins from disengaging. It can be applied to exterior wall cleaning and painting robots, effectively preventing secondary accidents caused by falling tools during high-altitude work.

Key Features:

• Maintenance equipment body equipped with a side docking pin on one side, an upper docking pin on the top, and a lower docking pin on the bottom
• Upper docking unit installed on the inner surface of the exterior wall climbing device to engage with the upper docking pin on the maintenance equipment body
• Lower docking unit that engages with the lower docking pin on the bottom, and a side docking unit that engages with the side docking pin on the side
• Structure that physically prevents the docking pins from disengaging by interlocking a hook-shaped docking pin catch with a docking hook
