Abstract

A pipeline robot with the pipe diameter self-adaption function comprises a planetary reducer, the input end of the planetary reducer is connected with a driving impeller, the output end of the planetary reducer is connected with a fixed guiding mechanism through a cardan joint, and a safety clutch is arranged between the planetary reducer and the cardan joint; ball screws with two end thread directions opposite are arranged on a shell of the planetary reducer, the two ends of the ball screws are sleeved with nut pairs, and the nut pairs are connected together through tension springs; each nut pair is connected with a wheel seat through a connecting rod, and driving wheels are arranged on the wheel seats; the output end of the planetary reducer is connected with the input ends of the ball screws through a gear system. The pipeline robot with the pipe diameter self-adaption function is simple in structure, low in machining cost and capable of automatically adjusting the own size according to the size of an obstacle to overcome the obstacle without manual adjustment; after the obstacle is overcome, the own size of the driving wheels can be automatically increased to move forward in a pipeline conveniently.

Description

technical field [0001] The invention relates to the field of pipeline robots, in particular to a pipe diameter self-adapting spiral pipeline robot, which is mainly used for the robot to automatically change its size when the pipe diameter changes and obstacles are large, so as to facilitate the smooth passage of obstacles and conduct pipeline detection. Background technique [0002] As the main fluid transportation tool, pipelines play a huge role in human production and life. In the long-term use of the pipeline, it is inevitable that there will be ruptures, blockages, etc., which requires us to regularly survey and maintain the pipeline. The pipeline robot has unique advantages in this regard. Among many pipeline robots, wheeled pipeline robots are widely used in pipeline inspection due to their fast speed, smooth motion and strong load capacity. The diameter reduction methods of existing pipeline robots include spring preload reduction, worm preload reduction and elevato...
