Self-centering self-walking full-rotating high-pressure water pipeline coating cleaning device

Abstract

The invention relates to a self-centering self-walking full-rotating high-pressure water pipeline coating cleaning device which is characterized by comprising a clamping centering outer frame, two clamping centering mechanisms with the same structures, a rotation and lateral moving mechanism, two inner rotation mechanisms with the same structures, a nozzle rotation frame, a nozzle rotation mechanism, a radial nozzle adjusting mechanism, high-pressure water nozzles and two walking support mechanisms with the same structures. According to set coating cleaning process flow requirements, the device is provided with work control mechanisms for centering, circumferential rotation and axial lateral moving of corresponding equipment and lateral moving walking corresponding functions for adjustingthe working position of the equipment, the equipment runs on a cleaned pipeline, the working position of the equipment is adjusted by controlling the rotating jet position of high-pressure water, anda pipeline coating can be rapidly, automatically and efficiently cleaned.

Description

technical field [0001] The invention belongs to the technical field of cement coating cleaning auxiliary equipment for submarine pipelines, in particular to a self-centering self-propelled full-rotation high-pressure water pipeline coating cleaning device. Background technique [0002] In the maintenance of gas pipelines and oil-gas mixed pipelines, the cleaning of cement coatings and anti-corrosion coatings on pipelines has always been a difficult problem. In the existing construction, the methods usually used to clean the cement coating and anti-corrosion layer outsourced by the pipeline are: high-temperature treatment method. It is difficult to use in the environment, and it is difficult to use underwater; the hydraulic pick impact method, the defect of this method is contact cleaning, which is easy to cause damage to the pipeline to be cleaned, affecting further construction, and the cleaning speed is slow; the hand-held high-pressure water method, this The defect of th...

Problems solved by technology

In the existing construction, the methods usually used to clean the cement coating and anti-corrosion layer outsourced by pipelines are: high-temperature treatment method. It is difficult to use in the environment, and it is difficult to use underwater; the hydraulic pick impact method, the defect of this method is contact cleaning, which is easy to cause damage to the pipeline to be cleaned, affecting further construction, and the cleaning speed is slow; the hand-held high-pressure water method, this The defect of this method is that the recoil force of high-pressure water is relatively large, and the diver's workload is large, so it is difficult to meet the requirements of long-term continuous work.

Since the above methods for cleaning pipelines have insurmountable defects, it is necessary to provide a reliable and effective construction equipment to meet the needs of pipeline coating cleaning
