Bidirectional moving inertia pipeline robot

Abstract

The invention provides a bidirectional moving inertia pipeline robot. At present, due to the structure, most pipeline robots can not work bidirectionally in high pressure, flammable and explosive, corrosive and other severe environments. The bidirectional moving inertia pipeline robot mainly comprises a shell and an inertia excitation mechanism. The inertia excitation mechanism comprises a rotation power source, three non-circular gear connected in series and two identical eccentric mechanisms, and the inertia excitation mechanism is arranged inside the robot shell. The two eccentric mechanisms are transmitted through a pair of synchronous cylindrical gears, revolving shafts of the two non-circular gears are connected with revolving shafts of the synchronous cylindrical gears respectivelythrough two overrun clutches, and the work directions of the two overrun clutches are opposite. The inertia pipeline robot moves through the mutual action of interior inertia and environment frictionforce, the defect that movable sealing must be arranged between a traditional power source and main driving feet can be overcome fundamentally by means of the driving mode, and the bidirectional moving inertia pipeline robot is suitable for small, high pressure, corrosive, flammable, high temperature and other extreme severe pipeline work environments.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a two-way motion inertial pipeline robot. Background technique [0002] With the rapid development of the level of industrialization in the international community, pipelines, as the main transportation facilities for fluids, are widely used in municipal, chemical, petroleum and nuclear power industries due to their economy and convenience. Corrosion, fatigue damage, breakage, etc. are prone to occur. If the pipeline is not repaired in time, it may cause economic losses, and the environment may also cause damage. However, the environment where the pipeline is often difficult for people to reach or cannot be directly repaired, so a new pipeline is needed Management mode, intelligent management is the inevitable trend and development direction of the pipe network system. [0003] As an important part of the intelligent pipeline network, pipeline robots can complete a s...

Problems solved by technology

This invention belongs to the screw-driven pipeline robot. Through the rotation of the screw drive head, the driving wheel walks along the spiral trajectory on the inner surface of the pipeline, so that the robot can move axially. The same screw drive head and the rear car body are dynamic seals. , the power system has great hidden dangers in the face of high pressure, flammable, corrosive and other harsh environments

[0009] At present, most pipeline robots cannot operate bidirectionally in harsh environments such as high pressure, flammable, explosive, and corrosive due to structural reasons.
