Pipeline detection robot

Abstract

The invention relates to a pipeline detection robot. The pipeline detection robot mainly comprises a laser detection mechanism (1), a traction mechanism (2), an electromagnetic ultrasonic detection mechanism (3) and an electronic cabin (4), all of which are connected through connecting hinge shafts; the traction mechanism (1) adopts a single-motor all-drive mode and is driven by a turbo-worm synchronous belt to supply a walking power to the robot; the laser detection mechanism (2) comprises a laser displacement sensor, a rotating arm, a counterweight, a support body and the like and is used for measuring surface corrosion and deformation of a pipeline; the electromagnetic ultrasonic detection mechanism (3) comprises a support assembly, a probe and a fixing plate and is used for measuring the wall thickness and the crack defect of the pipeline; the electronic cabin (4) is used for carrying auxiliary components, such as a stepping motor controller, a servo motor driver, a power supply and an FPGA (Field Programmable Gate Array) control panel. The pipeline detection robot disclosed by the invention can be used for finding the defects, such as pipeline corrosion, cracks and deformation, carrying out in-service detection on an oil and gas pipeline in a working process, carrying out targeted repair, maintenance and replacement according to a detection result, reducing the maintenance cost and guaranteeing safe and stable operation of the oil and gas pipeline.

Description

technical field [0001] The invention relates to a robot, in particular to a pipeline detection robot that applies various sensing detection technologies to detect corrosion, cracks, roundness and other defects of oil and gas pipelines in working state, so as to ensure the safe and stable operation of the pipelines. Background technique [0002] The pipeline detection robot is a special detection device developed for the cleaning, detection and maintenance of oil and gas pipelines. It integrates intelligent mobile technology and non-destructive testing technology to perform non-destructive testing on oil and gas pipelines in the working state to ensure the safety and stability of the pipeline. .

AI Technical Summary

Problems solved by technology

[0003] At present, most oil and gas pipeline detection robots at home and abroad use a single detection method. Although this method can detect pipeline defects, considering that magnetic flux leakage detection technology can only detect defects in a single direction, eddy current detection technology requires couplant and environmental and human factors. The impact is relatively large, and the magnetic memory detection technology is not yet mature.
