Sewer pipe repair robot and control method for the same

Sewer Pipe Repair Robot

This technology is a robot system for sewer pipe repair that features a modular design, separating the autonomous and remotely controlled mobile platform from the towed work platform.

Conventional drum-type chipping tools are difficult to assemble and install inside sewer pipes, and they face limitations in terms of work efficiency and cost-effectiveness.

This technology utilizes a crane-type work platform equipped with a pneumatic rock drill, separated from the mobile platform, and performs chipping operations through crawler-based movement and precision control. It can be applied to logistics, service robots, and autonomous driving platforms, thereby improving work productivity, addressing labor supply imbalances, and enhancing cost-efficiency in sewer pipe repair operations.

Key Features:

• A control unit that is electrically connected to the mobile platform, work platform, and chipping tool, and controls these components based on preset control signals and control signals generated from detection signals sensed during operation.
• A work platform provided on the upper side of the towing base, which rotates selectively to direct one end toward the target work area, either autonomously or via operator control, based on preset work path information.
• A servo cylinder coupled at its center to the top of the rotation support via a coupling shaft, which rotates on a horizontal axis relative to the coupling shaft and selectively extends or retracts the length of one end.
• A chipping tool provided at one end of the work platform that performs chipping on the target work area, either autonomously or via operator control, based on preset work path information.

This invention was developed with the support of the Ministry of Science and ICT for the commercialization of reinforced concrete chipping robots for the automation of box-type sewer pipe maintenance.
