A special automatic walking equipment for inner wall treatment of diesel pipeline

Abstract

The invention relates to special automatic walking equipment for treating the inner wall of a diesel oil pipeline. The special automatic walking equipment comprises two inner wall automatic walking branched chains, wherein four connecting reinforced columns are symmetrically connected between the two inner wall automatic walking branched chains and have a function of connecting and fixedly supporting the two inner wall automatic walking branched chains, besides, two telescopic walking branched chains are symmetrically mounted at the lower end of each inner wall automatic walking branched chain, the equipment automatically walks to the inner wall of the pipeline through the four telescopic walking branched chains, the four telescopic walking branched chains stretch outwards after the equipment walks to the inner wall of the pipeline, at the moment, the two inner wall automatic walking branched chains stretch outwards until being tightly attached to the inner wall of the pipeline, and the equipment can stably walk on the inner wall of the pipeline through the two inner wall automatic walking branched chains; each inner wall automatic walking branched chain comprises a square support block. According to the special automatic walking equipment for treating the inner wall of the diesel oil pipeline, the function of stable automatic walking on the inner wall of the diesel oil pipeline can be realized, and the conditions of rollover and vertical vibration possibly produced in a walking process are eliminated.

Description

technical field [0001] The invention relates to the technical field of petroleum pipeline machinery, in particular to a special automatic walking device for treating the inner wall of a diesel pipeline. 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 diesel 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 a...
