Adaptive inner wall pipeline robot

Abstract

The invention discloses a self-adaptive inner wall robot for a pipeline. The self-adaptive inner wall robot for the pipeline comprises three sections, namely, a middle part which is equipped with a cylinder, and two ends which are provided with air bag moving mechanisms, wherein the cylinder is divided into an upper independent cavity and a lower independent cavity; the air bag moving mechanisms are connected to the cylinder through ball hinges and a piston rod. The self-adaptive inner wall robot for the pipeline can effectively fit the variation of the inside diameter of the pipeline and can successfully move through a corner of the pipeline; an air feeding valve and an air exhausting valve of the cylinder can be operated to control the air feeding direction and the air exhausting direction of the cylinder, thus the piston rod in the cylinder can be controlled to move upwards and downwards so as to push the upper and lower air bag moving mechanisms, and as a result, the robot for the pipeline can be driven to move in two directions; after relative assisting tools are provided, the pipeline can be comprehensively and reliably detected; the robot is flexible, stable and reliable in movement.

Description

technical field [0001] The invention relates to a pipeline robot, more specifically, an active and passive control self-adaptive inner wall pipeline robot. Background technique [0002] As an important tool for material transportation, pipelines often need to be repaired for aging, cracking, corrosion, blockage, mechanical damage, weld quality, etc. during use, but pipelines are generally buried deep underground or in buildings, especially in interior The surface is not convenient for manual maintenance, and it is urgent to develop various pipeline robots. However, at present, pipeline robots mainly rely on wheels or suction cups to make contact with the inner wall of the pipeline, which will cause many problems, such as: they can only walk in straight pipelines with a fixed diameter, and once the diameter of the pipeline changes or the pipeline is bent, it will be stuck. For this reason, the present invention proposes an adaptive inner wall pipeline robot capable of changi...
