Abstract

The invention discloses a circulating variable-pitch propeller pipeline robot comprising a guide rod, a linear telescopic motor, a guide wheel, a motion coordinating disc, a fish eye ball head, a telescopic short joint, a driving wheel, a driving wheel supporting rack and a motor having a decelerating set. A rotary bearing is installed in the motion coordinating disc; the center of the rotary bearing is covered with a fish eye bearing; the guide rod is covered with the fish eye bearing in a slide way; the guide wheel is connected with the linear motor telescopic motor; the fish eye ball head is assembled on the linear telescopic motor and in a sleeved connection with a control rod of the motion coordinating disc; the driving wheel is connected with the motor having the decelerating set and installed on the telescopic short joint; the telescopic short joint is connected with the guide rod via the driving wheel supporting rack; a ball head is assembled on the telescopic short joint; the ball head is connected with the ball head on the rotary bearing via a connection rod; and the guide rod is connected with the ball head on the rotary bearing via a synchronous connection rod. The circulating variable-pitch propeller pipeline robot can flexibly move and possesses great traction force, and can be suitable for composite pipeline interior work in a better way.

Description

Technical field [0001] The invention relates to a pipeline robot, in particular to a cyclic variable pitch spiral pipeline robot which can conveniently realize speed control and turning. Background technique [0002] In modern production and life, there are numerous pipeline networks of various types, such as oil and gas, water delivery, and heating. During the long-term use of the pipeline, due to chemical corrosion, mechanical damage, crustal movement, wear of pipeline accessories, etc., damages such as corrosion, deformation, cracks and other forms are prone to occur. A large part of the pipelines are buried pipelines. The hidden dangers of pipeline leakage are difficult to find, which can easily cause fires, explosions and other dangerous situations, posing a serious threat to the safety of people's lives and properties, and also seriously affecting economic benefits. However, when a leak is found to be dangerous, downtime for maintenance will also cause huge economic losses...
