Uniform supporting and traveling device for inner wall of oil pipe

Abstract

The invention relates to a uniform supporting and traveling device for the inner wall of an oil pipe. The uniform supporting and traveling device for the inner wall of the oil pipe comprises a square supporting block. Four automatic traveling mechanisms are mounted on the four side walls of the square supporting block correspondingly. The four automatic traveling mechanisms work in four directions at the same time. Four uniformly-distributed traveling and supporting forces are provided, so that the uniform supporting performance is good, and the self-stabilizing traveling performance is good. Each automatic traveling mechanism comprises a traveling bottom plate which is welded to the corresponding side wall of the square supporting block, wherein two first hydraulic cylinders are mounted on the two sides of the upper end face of the traveling bottom plate, two first flanges are mounted on the two first hydraulic cylinders through threads correspondingly, and a traveling installation table is mounted at the upper ends of the two first flanges through screws correspondingly; and the two first hydraulic cylinders and the traveling installation table are connected through the two first flanges, and two positioning columns are symmetrically arranged on the middle portion of the upper end of the traveling bottom plate. According to the uniform supporting and traveling device for the inner wall of the oil pipe, the function of stable uniform limited traveling on the inner wall of a petroleum pipeline can be achieved, and the situations of possible rollover and up-down vibration of the uniform supporting and traveling device in the traveling process are eliminated.

Description

technical field [0001] The invention relates to the technical field of oil pipeline machinery, in particular to a uniformly supporting running device for the inner wall of oil pipelines. Background technique [0002] With the rapid development of the petroleum industry, more and more oil pipelines and water injection pipelines are used in oil fields. Oil and water usually contain corrosive substances, which often lead to pipeline corrosion damage, especially the life of oil pipelines with high water content and sewage reinjection pipelines is greatly shortened, and the replacement of new pipelines faces huge costs. Corroded old pipelines need anti-corrosion treatment. The main way of oil pipeline anti-corrosion is to spray anti-corrosion coating on the inner wall of the pipeline. Before the existing automation equipment sprays the anti-corrosion coating, it is necessary to move the spraying equipment to the inner wall of the pipeline through the existing automatic pipeline w...
