Abstract

The invention relates to a miniature spiral pipeline robot. The miniature spiral pipeline robot comprises a short drive joint and a short moving joint. The short drive joint comprises a drive motor, a power source, a controller and a righting mechanism. The drive motor is fixedly connected with guide wheel frames. Guide wheel arms on the guide wheel frames are connected with guide wheels. Elastic force is provided through torsion springs, so that the guide wheels make tight contact with a pipeline. The short moving joint comprises a machine body, a driving wheel, a driving wheel frame, a variable diameter rod, a spring, an angle adjustment sleeve, an angle adjustment motor, a transmission mechanism, a battery, a single-joint controller and a centering mechanism which is composed of the guide wheel frames, the guide wheel arms, the guide wheels, the torsion springs and bearings. The angle adjustment motor is connected with the angle adjustment sleeve through the transmission mechanism. The driving wheel is installed on the driving wheel frame. The driving wheel frame is fixedly connected with the variable diameter rod. Pre-tightening force between the driving wheel and the pipeline is adjusted through the spring. The miniature spiral pipeline robot is capable of passing the curved pipeline conveniently. Moving is flexible, and traction is large. The miniature spiral pipeline robot can be adapted to operation in the miniature pipeline very well.

Description

technical field [0001] The invention relates to a miniature spiral pipeline robot, which belongs to the technical field of robots. Background technique [0002] As an important device for transporting fluids, pipelines play a huge role in human production and life. The transmission medium in the pipeline is special and the external environment is harsh. Therefore, after the pipeline has been in operation for a period of time, it is often necessary to carry out inspection and maintenance operations to ensure the smooth progress of production and the safety of people's lives. [0003] The pipeline robot is a pipeline delivery tool, which is used to realize pipeline operations such as pipeline status monitoring, fault maintenance, and operation tool transportation. At present, pipeline robots mainly include: pipeline pig type, which drives the robot through the fluid pressure difference between front and back; wheel type or crawler type, which drives the robot through the cont...
