Preparation device for preparing anticorrosive coating on outer surface of pipeline

Abstract

The invention relates to a preparation device for preparing an anticorrosive coating on the outer surface of a pipeline. The preparation device comprises a bottom frame which is used for being movably assembled on a track extending in the axial direction of the pipeline in a guiding mode. The bottom frame is provided with a cloth roll installing rack used for installing a cloth roll and further provided with a paint spraying mechanism. The paint spraying mechanism comprises a primer spraying mechanism body used for spraying primer on the peripheral surface of the rotating pipeline and / or an outer-layer paint spraying mechanism body used for spraying outer-layer paint on a cloth belt wound on the peripheral surface of the pipeline. Primer spraying, cloth belt winding and outer-layer paint spraying can be achieved at the same time, the efficiency is high, and too much manual intervention is not needed, so that the labor intensity is relieved; and meanwhile, the rotating pipeline and the movable bottom frame are matched with each other, accordingly, the paint spraying thickness and the cloth belt winding thickness can be accurately controlled, and the uniformity and the quality of the prepared anticorrosive coating can be effectively improved.

Description

technical field [0001] The invention relates to a preparation device for preparing an anticorrosion layer on the outer surface of a pipeline. Background technique [0002] Wrap the fiber cloth tape outside the pipe, and spray the paint layer on the layer. After it is cured naturally, a certain thickness of anti-corrosion layer will be formed. In fact, at present, most of the fiber cloth tapes are wound on the primed pipeline, and then the outer paint is applied to form an anti-corrosion layer, thereby completing the preparation of the anti-corrosion layer on the outer surface of the pipeline. [0003] At present, most of the workers manually prepare the anti-corrosion layer on the outside of the rotating pipe. One worker sprays the primer on the rotating pipe, one worker winds the cloth tape on the pipe while rotating, and another worker sprays the outer layer on the outer layer of the cloth tape. Layers of paint. This method of manual on-site construction has cumbersome t...
