A cleaning and painting device for welded ring joints used for laying oil pipelines

Abstract

The invention discloses a welding ring seam cleaning and painting device for laying oil pipelines, which comprises a triangular bracket, a mounting base, a first motor crawler assembly, a second motor crawler assembly and an electromagnet. The vertical pipe, and the bottom bearing sleeve of the positioning vertical pipe is provided with a positioning sleeve, the outer wall of the bottom of the mounting base is fixedly installed with a shell, and the top center of the mounting base is fixed with the first motor track assembly, and the inner sleeve of the outer cylinder A positioning horizontal tube is provided, and a connecting ring is sleeved on the right outer wall of the positioning horizontal tube, and a paint injection pipe is installed through the inside of the positioning horizontal tube. The welded ring seam cleaning and painting device for oil pipeline laying is convenient for the overall splicing and installation positioning of the device, improves the efficiency and molding quality of ring seam cleaning and painting, reduces labor consumption of manual operations, and makes cleaning and painting two operations Synchronized and divided into categories, the interaction does not interfere with each other.

Description

technical field [0001] The invention relates to the technical field related to the laying of petroleum pipelines, in particular to a cleaning and painting device for welded ring seams used for laying petroleum pipelines. Background technique [0002] When laying and installing oil pipelines, it is necessary to carry out butt positioning between adjacent pipeline ends according to the length and diameter selected for use. In order to improve the stability and sealing of the pipeline end butt joints, it is necessary to splice them The positioned pipe ends are welded and reinforced, and the presence of welded seams is prone to oxidation-reduction reactions due to long-term external placement and rainwater invasion, resulting in loosening of the pipe connection and resulting in shedding. In order to prolong the service life of the pipe, the ring seam After welding, it is necessary to use an external cleaning and painting mechanism to realize the cleaning and painting of the pipe...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a welding ring seam cleaning and painting device for laying petroleum pipelines, to solve the above-mentioned background technology. The step-by-step paint operation will greatly prolong the time-consuming of the circular seam treatment, increase the unnecessary working hours, and the labor consumption of manual assistance is large, and it is easy to cause the circular seam to be broken due to the unstable positioning and shaking of the manual operation. The distribution of the paint protection layer is not uniform enough, which affects the effect of the isolation and protection treatment of the circular seam
