Problems solved by technology

[0004] However, the camera detection crawler inside the pipeline also has limitations in the detection of the internal conditions of the pipeline
Usually, the smaller the inner diameter of the pipeline, the smaller the size of the entry-type robot, and the shorter the length of the cable it carries, which also limits the length of the pipeline camera inspection. It reaches about 500 meters, and the length of oil and gas gathering and transportation pipelines is mostly several kilometers or tens of kilometers, which limits the application of pipeline inspection robots in composite pipe oil and gas gathering and transportation pipelines

Abstract

The invention discloses an extending device for a long-distance crawling detection robot in a pipeline and an extending method of the extending device. The extending device comprises a crawling body,a power transmission module, a communication transmission module, an intelligent control module, a driving module and cable connecting joints; the power transmission module, the communication transmission module, the intelligent control module and the driving module are arranged inside the crawling main body, and the driving module is used for driving the crawling body to move; the two cable connecting joints are arranged on the two sides of the crawling body respectively; and the power transmission module, the communication transmission module, the intelligent control module and the driving module arranged inside the crawling body are all connected with cable connecting joints on the two sides. The extending device and the extending method has the advantages of being simple in design structure, easy to implement, low in economic cost, high in reliability and facilitates popularization and use of an oil field and an urban pipe network operation site.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, and in particular relates to a long-distance crawling detection robot extension device and an extension method in a pipeline. Background technique [0002] In recent years, due to the excellent corrosion resistance and high cost performance of carbon steel / low alloy steel lined stainless steel bimetallic composite pipes, they have been widely used in oil and gas gathering and transportation pipelines, but there are also relatively prominent problems that plague the safe production of oil fields. . During the operation of the bimetallic composite pipe, due to defects in manufacturing and on-site construction, the lining collapse problem is more likely to occur. As a result, the pipeline cannot be regularly inspected for the ball and the inner lining, and the remaining service life of the pipeline cannot be actively grasped. Corrosion can only be used. Passive treatment after puncture l...
