Crisscross Crawler Belt Robot for Pipeline Obstacle Crossing

The crawler belt system employs dynamic tilt angle adjustment mechanisms that allow the crawler belts to change their inclination angles relative to the pipeline wall based on the detected pipeline curvature and obstacle conditions. This dynamic adaptability enables the robot to navigate different pipeline types without requiring complex auxiliary mechanisms, as the tilt angles are continuously adjusted in real-time based on sensor feedback.

The system changes the operational parameters of the crawler belts by adjusting tilt angles, rotation speeds, and propulsion forces based on real-time environmental sensing. This parameter adaptation allows the same crawler belt structure to handle various pipeline configurations and obstacles, eliminating the need for multiple specialized mechanisms.

The obstacle crossing capability is achieved through dynamic adjustment of crawler belt tilt angles and propulsion characteristics. When obstacles are detected, the system automatically adjusts the crawler belt parameters to optimize contact and force distribution, eliminating the need for separate auxiliary crossing mechanisms while maintaining high obstacle negotiation ability.

The primary crawler belts are designed to perform multiple functions: propulsion, obstacle crossing, and adaptation to different pipeline geometries. By integrating these functions into a single universal system with adjustable parameters, the patent avoids adding separate auxiliary mechanisms, thereby reducing overall device complexity while maintaining versatile obstacle crossing capability.

The contact positions between crawler belts/traveling wheels and the pipeline wall are made dynamically adjustable rather than fixed. The system continuously senses pipeline inner conditions and adjusts the contact positions to optimize distribution and minimize concentrated stress points, thereby reducing abrasion while maintaining structural simplicity through software-controlled adaptation.

The robot autonomously adjusts its own contact positions with the pipeline wall based on real-time sensing of pipeline conditions. This self-adaptation mechanism allows the system to automatically optimize its configuration to minimize wear on crawler belts and traveling wheels without requiring complex external adjustment mechanisms, balancing simplicity with reliability.
