Adjustable suction and application anticorrosion device for internal surface of oil exploitation pipe

Abstract

The invention provides an adjustable suction and application anticorrosion device for the internal surface of an oil exploitation pipe. The adjustable suction and application anticorrosion device comprises a chassis, a power box, a first supporting plate, a control box, a coating box, telescopic power pushing frame structures, a rotatable telescopic supporting pipe structure, a detectable rotatingcleaning brush structure, a cleanable spraying frame structure, a programmable logic controller (PLC), a wireless transmission module, a spraying pump, a miniature air pump, a second supporting plate, a rotating motor, a fixing bolt, a supporting pipe and a supporting rotating pipe. The power box is in bolted connection with the middle position of the lower end of the chassis. By arranging the chassis, the first supporting plate, a connecting rod, a telescopic pipe, an adjusting bolt and a rubber wheel, the adjusting bolt is beneficially loosened during working, then the telescopic pipe is pulled up and down, the rubber wheel makes contact with the inner wall of a pipeline, then the adjusting bolt is tightened, support of equipment is facilitated during working, and the situation that during working, the equipment tilts and affects the working quality is prevented.

Description

technical field [0001] The invention belongs to the technical field of suction coating anticorrosion devices, in particular to an adjustable suction coating anticorrosion device for the inner surface of oil exploitation pipes. Background technique [0002] Petroleum pipes are seamless steel pipes suitable for furnace tubes, heat exchangers and pipes in petroleum refineries. Steel pipes for geological drilling are steel pipes for core drilling in geological departments. According to their uses, they can be divided into drill pipes, drill collars, core pipes, Casing and sedimentation pipes, etc. The oil pipe is a long steel material with a hollow section and no joints around it. The oil cracking pipe is an economical cross-section steel. Anti-corrosion work on the inner wall. [0003] However, the existing suction anticorrosion device still has the disadvantages that it is inconvenient to carry out support work in the process of using, it is inconvenient to adjust the height ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an adjustable anti-corrosion absorption device for the inner surface of oil production pipes, so as to solve the problem that the existing anti-corrosion absorption device is inconvenient to carry out support work in the process of use. It is inconvenient to adjust the height when the inner wall is moving, it is inconvenient to blow away the dust generated when cleaning the inner wall of the coffin, and it is inconvenient to check the pressure during work inspection and grinding
