Large-Scale Pipeline Robot

This invention adopts a modular integrated design, enabling the pipeline cleaning robot to be applied to large-diameter pipelines ranging from 24 to 36 inches. The structural feature of the machine is a pipe-wall support type with four sets of support structures, allowing the robot to operate inside horizontal or vertical pipelines for crawling, inspection, cleaning, and engineering operations. The structural design consists of four parts: the robot body, the control system, the transmission system, and the intelligent backend management system.

Robot Body: Features an innovative power structure design in which multiple power modules can adjust the gap between the front and rear tracks, enabling operation inside vertical, horizontal, bent, and T-junction pipelines. ulti-Function and Inspection Module: Integrates height-adjustable brushes and suction tools for engineering purposes, capable of removing welding slag and foreign objects. It also includes a three-axis robotic arm for gripping large foreign objects inside the pipe. Equipped with a camera, it can assess the degree and location of cleaning and perform inner wall inspections.

Transmission System: Uses a 50〜200 m fiber-optic composite cable combined with length measurement to determine the insertion distance into the pipeline, while providing power and communication signals.

Control System: Includes a monitoring screen, recording function, position tracking, robot posture display, cleaning function control, pipeline inner wall inspection, and condition marking.

Intelligent Backend Management System: Incorporates access control and real-time internal pipeline image annotation functions.
