Abstract

In order to enable a pipeline robot to suit pipelines with diameters in the range of 400～650 mm

three commonly used regulating mechanisms are proposed by analyzing the mechanical properties of each type of regulating mechanism and comparing the advantages and disadvantages of these regulating mechanisms. A ball screw pair regulating mechanism has been chosen to satisfy the actual engineering needs of this subject under investigation. The cylindrical pressure sensor on the ball screw can keep the pressure between the driving wheel and the pipe inner wall always stable so that the pipeline robot has adequate and stable traction force. Experimental results show that this regulating mechanism has a traction force output of 1404 N

and it can be used to suit pipelines with pipe diameters in the range of 400～650 mm very well.
