External corrosion prevention integrated equipment for oil-water well pipeline

Abstract

The invention relates to external corrosion prevention integrated equipment for an oil-water well pipeline. The equipment comprises X-direction guide rails which are parallel to the oil-water well pipeline and extend in a left-right direction; the two X-direction guide rails are parallel to each other and are fixed on the ground at the rear side of the pipeline; a fixed bottom plate capable of advancing along the guide rails is supported on the two X-direction guide rails; a movable bottom plate is hinged to the fixed bottom plate; an asphalt paint dipping tank is fixed above the middle part of the movable bottom plate; a cloth roller extending in an X direction is arranged behind the asphalt paint dipping tank; a glass fiber cloth roll is wound on the cloth roller; a cloth dipping rolleris arranged in the asphalt paint dipping tank; a pair of rollers is arranged in front of the asphalt paint dipping tank; glass fiber cloth led out of the glass fiber cloth roll penetrates through therollers upwards after being wound on the cloth dipping roller downwards, and then wraps the oil-water well pipeline forwards; a horizontal swing air cylinder is hinged to the rear portion of the movable bottom plate; and the outer end of the horizontal swing air cylinder is hinged to a supporting seat on the outer side of the fixed bottom plate. The external corrosion prevention integrated equipment for the oil-water well pipeline can safely and efficiently complete external corrosion prevention work of the pipeline with low strength.

Description

technical field [0001] The present invention relates to a special maintenance tool for oil and water wells, in particular to an integrated anti-corrosion equipment for oil and water well pipelines, which is mainly used in the common automatic anti-corrosion work in the external anti-corrosion work of pipelines, including automatic rust removal, cloth wrapping, painting, etc. It belongs to the technical field of anticorrosion of oil and water well pipelines. Background technique [0002] In the external anti-corrosion work of oilfield pipelines, the steel pipe needs to be derusted first, and then frequently wrapped and painted. At present, two people lift the pipe, two people hold the steel pipe to rotate, two people manually wrap the cloth, and two people The wrapped cloth is manually painted, and the operation is repeated until the construction of a steel pipe "four oils and four cloths" is completed. Since there is no special tool, eight operators are required to cooperat...

AI Technical Summary

Problems solved by technology

Since there are no special tools, eight operators are required to cooperate with the operation, which is labor-intensive. It requires not only tube transfer, cloth wrapping, but also manual painting, which requires a large amount of labor and low efficiency.

Manual tube transfer has no stable speed and relies purely on the experience of the operator. Manual cloth wrapping and manual painting are prone to instability, high risk, and easy to cause serious mechanical damage. There are greater safety and quality hidden dangers

[0003] In addition, rust removal is very time-consuming and laborious, and the dust caused is large, which is not conducive to the labor protection of workers. In actual work, rust removal is easy to be incomplete, resulting in a decline in anti-corrosion quality and affecting the service life of the pipeline.
