A spiral pipe inner wall grinding and polishing robot adaptable to different pipe diameters

Abstract

The invention relates to a spiral pipeline inner wall grinding and polishing robot suitable for different pipe diameters, and belongs to the field of pipeline robots. A hub assembly and a cross-axis universal joint are mounted in a spline fit manner, three driving wheel grinding assemblies are arranged, two ends of drive shafts of the assemblies and a drive shaft support in the hub assembly are mounted in a matched manner through bearings, a motor and control and power assembly is mounted on a direction keeping mechanism, and a motor shaft of the assembly and the cross-axis universal joint are mounted in a spline fit manner. The spiral angles of the grinding assemblies relative to the cross section of a pipe fitting are adjusted in a self-adaptation manner, and therefore the aim that the position with the small pipe diameter and many impurities is ground much, and the position with the large pipe diameter and few impurities is ground little is achieved, the robot can be matched with multiple different-size grinding assemblies for use, the aim that one robot has multiple purposes is achieved, and the cost can be saved to a certain degree.

Description

technical field [0001] The invention belongs to the field of pipe robots, in particular to a spiral pipe inner wall grinding and polishing robot that can adapt to different pipe diameters. Background technique [0002] In people's life, there are various pipelines, such as oil pipelines, natural gas pipelines, tap water pipelines and so on. Many of these pipelines are not large in diameter, which brings a lot of inconvenience to their detection and maintenance, and the pipeline robot came into being. [0003] The smoothness of the inner wall of the pipeline is very important. If the inner surface of the pipeline is relatively rough, it will more easily lead to the accumulation of sediment on the inner wall of the pipeline, which will reduce the effective working area of ​​the pipeline and even cause blockage. Therefore, it is very necessary to grind and polish the inner wall of the pipeline. However, although there are many types of existing pipeline robots, there are very...
