Abstract

The invention relates to the technical field of mechanical structures of pipeline robots, in particular to a composite driven pipeline robot applicable to multiple detection working conditions. The composite driven pipeline robot is provided with a leather cup, a first-stage driving mechanism and a second-stage driving mechanism, and is characterized in that the first-stage driving mechanism is composed of a discharge motor, a mounting plate, an inner rotating cylinder and an outer sleeve; the right side face of the first-stage driving mechanism is provided with the second-stage driving mechanism; the second-stage driving mechanism is composed of a left connecting plate, a right connecting plate, a driving motor, a motor fixing plate, a support sleeve, support assemblies and driving assemblies; the three driving assemblies are evenly arranged between the left connecting plate and the right connecting plate; each driving assembly is composed of a belt, a transmission gear train, a bearing plate, a driving wheel, an active wheel, a passive wheel, a bearing shaft and a bracket; and each support assembly is composed of a driving spring, a support sliding block, a support arm, an electromagnet, a positioning base, a sliding shaft and a support base. The pipeline robot has the advantages of being simple in structure, high in detection quality and detection working condition adaptability and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical structure of pipeline robots, in particular to a compound-driven pipeline robot adaptable to multiple detection working conditions with simple structure, high detection quality and strong adaptability to detection working conditions. Background technique [0002] As we all know, since the end of the 20th century, with the continuous expansion of my country's energy demand and the optimization of energy consumption structure, as an important pillar of national economic construction, my country's oil and gas pipelines have been developing faster and faster. It is estimated that by 2020, China's long-term The construction mileage of oil and gas pipelines will reach at least 140,000 kilometers. However, oil and gas pipelines are usually placed underground, and are affected by water, oil, gas, soil, microbial corrosion, and oxygen penetration, resulting in different degrees of corrosion and perforati...

Problems solved by technology

[0004] In the actual engineering inspection process, the controllability of the motion speed of the differential pressure pipeline robot is poor, and it cannot run at low speed near the pipeline defect and carry out accurate detection; When other obstacles hinder the robot greatly, the differential pressure pipeline robot is stuck in the pipeline because it is difficult to overcome the frictional resistance, which makes the robot "go and never return" and affects pipeline transportation
