Abstract
An intelligent maintenance and repair robot for small diameter and small flow oil and gas pipelines, including a frame, a speed control mechanism, a braking mechanism, an anchoring mechanism, and a sealing mechanism; the speed control mechanism is composed of a motor, rotor, etc; the braking mechanism is composed of a braking rubber cylinder and a first extrusion ring; the anchoring mechanism is composed of a rubber conical cylinder, slips, etc; and the sealing mechanism is composed of a sealing rubber cylinder and a second extrusion ring. The second extrusion ring is driven by a hydraulic rod to press the sealing rubber cylinder, causing it to expand and block the pipe wall to achieve sealing. The intelligent maintenance and repair robot inside the pipeline has the characteristics of good speed control response, wide speed range, strong ability to pass bends, stable braking process, and high sealing reliability.
