Control system and method of anticorrosion spraying equipment of pipeline outer wall

Abstract

The invention relates to a control system and method of anticorrosion spraying equipment of a pipeline outer wall. The control system of the anticorrosion spraying equipment of the pipeline outer wall comprises an industrial personal computer, a PLC (Programmable Logic Controller), an operation panel, a text display, a spraying gun up-down movement system, an equipment wall-around walking system and a spraying system. The control method of the anticorrosion spraying equipment of the pipeline outer wall comprises the following steps: (1) initializing the system; (2) opening a spraying gun and driving, by a servo motor, the spraying gun to move upward through a chain until the spraying gun moves to an upper limiting switch; then closing the spraying gun and finishing one time of spraying from bottom to top; (3) enabling the whole spraying equipment to walk for 40cm around the pipe wall; (4) moving the spraying gun from top to bottom until the spraying gun meets a lower limiting switch, and closing the spraying gun; meanwhile, stopping downward movement so as to finish one time of spraying from top to bottom; (5) enabling the spraying equipment to walk for 40cm around the pipe wall and stopping; (6) judging whether spraying is finished or not; if not, entering step (2); otherwise, finishing the operation.

Description

technical field [0001] The invention belongs to the technical field of automation equipment, and in particular relates to a control system and method for anticorrosion spraying equipment on the outer wall of a pipeline. Background technique [0002] Large pipelines are a tool for transporting water resources. Due to the convenience of water resources transportation, pipelines are often buried underground. In order to prolong the service life of pipelines and ensure the reliability of water resources transportation, it is necessary to do anti-corrosion treatment on the outer wall of the pipeline. [0003] At present, the anti-corrosion treatment of the pipeline is completed by manually spraying the anti-corrosion liquid on the outer wall of the pipeline. Due to the high pipeline, about 6 meters, and the anti-corrosion paint is toxic, if manual spraying is used, there will be problems such as low efficiency, high risk factor, and uneven spraying. In order to improve the sprayi...

Problems solved by technology

Due to the high pipeline, about 6 meters, and the anti-corrosion paint is toxic, if manual spraying is used, there will be problems such as low efficiency, high risk factor, and uneven spraying. In order to improve the spraying efficiency and uniformity of the pipeline and reduce the danger of the workers Therefore, it is necessary to develop anti-corrosion spraying equipment for the outer wall of the pipeline, and develop its control system on this basis to realize the automation of the anti-corrosion spraying for the outer wall of the pipeline.
