Pipeline moving mechanism with self-adaption function

Abstract

The invention belongs to the field of mechanical automation engineering, and particularly relates to a pipeline moving mechanism with a self-adaption function. A plurality of motor driving mechanisms are distributed uniformly on the circumference of a central fixing component; each motor driving mechanism is connected with the central fixing component through a spring folding mechanism; driving module pedrail wheel systems are installed on both sides of each motor driving mechanism; the radial distance between the motor driving mechanisms and the central fixing component is changed through extension and extraction of the spring folding mechanism so as to adapt pipelines of different diameters; the pipeline moving mechanism moves in pipelines of different diameters under the driving of the motor driving mechanisms; and the driving module pedrail wheel systems on two sides of at least one motor driving mechanism abut against the inner wall of a pipeline in the moving process all the time. According to the pipeline moving mechanism with the self-adaption function, the structure is simple and compact; few corollary devices are required and the operation is easy; and the pipeline moving mechanism can adapt pipelines of different diameters, advance and retreat in the pipelines and sheer as the pipelines bend.

Description

technical field [0001] The invention belongs to the field of mechanical automation engineering, in particular to a pipeline moving mechanism with self-adaptive function. Background technique [0002] With the development of economy and society, pipelines, as the main transportation facilities of fluids, are widely used because of their convenience and economy. Our country has built a large number of underground pipeline systems to transport natural gas, oil and other fluids. Ensuring the safety and effectiveness of these pipeline systems is critical to our nation's energy security. However, as the service life increases, the pipeline will inevitably age, crack, corrode or be damaged by external construction. If it is not dealt with in time, once an accident occurs, it will bring huge losses to the country and the environment. Therefore, it is very necessary to inspect and maintain the pipeline regularly. [0003] As an effective detection device, the pipeline robot can g...
