Abstract

The invention provides a supporting wheel type pipeline robot driving device which is characterized in that a supporting motor gear drives a front bearing embedded gear together with a screw rod to rotate; the rotation of a screw rod is converted to the translation of a nut along the axial direction of the screw rod by a thread pair; a lower supporting arm bracket fixedly connected with the nut synchronously moves along with the nut and controls a position of a lower supporting arm relative to supporting points of a middle shaft rack supporting roll and a main supporting arm, and then expansion / retraction of a supporting arm assembly, and compression on a pipe wall are realized to be adapted to variance in the pipe diameter; in addition, a travelling motor gear drives an inner gear ring and an outer gear ring in interference fit with the inner gear ring in an inner and outer sleeve gear assembly to rotate with a gear ring bearing inner race jointly, then the outer gear ring serves as a driving part to drive three travelling gear assemblies to input straight gears, and finally drives travelling wheels to rotate along the pipe wall. The supporting wheel type pipeline robot driving device is particularly applicable to intra-pipe travelling operation, and has the characteristics of the adaptive capacity to environment of a pipeline is high, a tractive force is high, and the operation is smooth and reliable.

Description

technical field [0001] The invention belongs to the field of pipeline robots, in particular to a driving device for supporting wheeled pipeline robots. Background technique [0002] As an important material transportation method, pipelines are widely used in long-distance oil, natural gas, city gas, nuclear industry and other fields. In order to improve the service life and safety of the pipeline, it is necessary to carry out regular inspection and maintenance on the pipeline. As an efficient and accurate fault diagnosis, defect detection, and pipeline maintenance carrier, pipeline robots are being widely used in pipeline cleaning, weld inspection, joint repair, and defect detection, maintenance, and pigging during pipeline operation. [0003] According to the power source of the pipeline robot moving in the pipeline, the pipeline robot is divided into two types: passive motion mode and active motion mode. The passive motion mode pipeline robot mainly refers to the PIG driv...
