Limiting rotation type device for cleaning inner wall of petroleum pipeline

Abstract

The invention relates to a limiting rotation type device for cleaning the inner wall of a petroleum pipeline. The device comprises an annular rack. Two arc-shaped limiting openings are formed in each of the upper end and the lower end of the annular rack, and two cleaning support plates are welded to the inner wall of each of the two ends of the annular rack; a cleaning rotary shaft is installed between the two cleaning support plates through bearings, and a cleaning motor is installed at the right end of the cleaning rotary shaft through a coupler; the cleaning motor is a waterproof servo motor, the bottom end of the cleaning motor is installed on a cleaning concave frame through a motor seat, and the cleaning concave frame achieves the effect of stably supporting the cleaning motor; the cleaning concave frame is welded to the positions, located on the right side of the annular rack, of the side walls of the cleaning support plates; and four support rib columns are symmetrically welded to the side wall of each cleaning support plate, and cleaning connecting plates are welded to the tail ends of the four support rib columns on the side wall of each cleaning support plate. The function of rapidly and automatically cleaning the inner wall of the petroleum pipeline can be achieved, and the advantages of being high in equipment cleaning speed and equipment cleaning efficiency and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of oil pipeline machinery, in particular to a position-limited rotation type oil pipeline inner wall cleaning device. 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 . First move th...
