A uniformly supported walking type petroleum pipeline inner wall drying equipment

Abstract

The invention relates to uniform support walking type drying equipment for the inner wall of a petroleum pipeline. The uniform support walking type drying equipment comprises an inner wall automatic walking device, wherein the inner wall automatic walking device walks on the inner wall of the pipeline in four directions in a self-stabilizing manner, has four walking support forces which are uniformly distributed, is great in uniform support performance and is great in self-stabilizing walking performance, so that the overturning condition and the vertical vibration condition possibly occurring in a walking process are eliminated; and an inner wall drying device is mounted at the left end of the inner wall automatic walking device, and the inner wall drying device can realize a rapid drying function on the inner wall of the pipeline, can carry out partial rapid drying according to actual conditions of the inner wall of the pipeline, is wide in the range of applications, is great in power saving performance and is great in drying effect. The uniform support walking type drying equipment can realize a stable automatic drying function on the inner wall of the petroleum pipeline and has the advantages that the uniform support walking type drying equipment is great in uniform support performance on the inner wall of the pipeline, is great in equipment self-stabilizing walking performance, can carry out partial rapid drying, is great in power saving performance, is great in drying effect and the like.

Description

technical field [0001] The invention relates to the technical field of petroleum pipeline machinery, in particular to an evenly supported walking type petroleum pipeline inner wall drying equipment. 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 is sprayed with anti-corrosion coating, it is usually necessary to carry out the following processes on the inner wall of the oil pipeline: 1 . ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a drying equipment for the inner wall of the oil pipeline with uniform support and walking, which can solve the problems of the existing drying equipment for the inner wall of the oil pipeline, such as poor uniform support performance of the inner wall of the pipeline, poor self-stable walking performance of the equipment, and inability to carry out Partial range drying, large power waste, poor drying effect and low working efficiency can realize the stable automatic drying function of the inner wall of the oil pipeline, high working efficiency, good uniform support performance of the inner wall of the pipeline, and self-stable walking performance of the equipment Good, localized rapid drying, good power saving performance and good drying effect, etc.
