Automatic control system of horizontal type coated pipeline

Abstract

The invention relates to a coating production technology and particularly relates to an automatic control system of a horizontal type coated pipeline. The automatic control system is characterized by comprising a material supplying system for providing a coating raw material and a coating trolley for horizontally placing a pipeline or a steel bar cage, wherein the upper end of the material supplying system is provided with a casting wheel for coating work; the coating trolley carries the pipeline or the steel bar cage to be coated to do horizontal straight-line movement along the lower end of the casting wheel; and a process of uniformly coating is finished by taking the pipeline or the steel bar cage to be coated as a self axis as a center to be rotatably matched with the coating raw materials sprayed out by the casting wheel. According to the automatic control system disclosed by the invention, a horizontal coating manner is adopted so that the safety is greatly improved, the size limitation on the coated pipeline does not exist and the energy consumption of a coating production line is greatly reduced; the automatic control system is good for recycling the coating raw materials and reducing air pollution; and a workshop space of the coating production line is greatly reduced and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to coating production technology, in particular to an automatic control system for horizontal coating pipelines. Background technique [0002] Oil and gas transmission pipelines and cement pipes will be coated with a layer of concrete on the surface before use. At present, vertical coating is mostly used in oil and gas transmission pipelines and cement pipe coating concrete production lines. [0003] This vertical coating production line fixes the coating pipeline on the transmission system below it, drives the coating pipeline to rotate through the transmission system, and the projecting wheel coats the concrete from the mixing station on the coating pipeline in a high-speed striking manner. And move up or down to complete the coating process. [0004] The production line adopts the vertical coating method, and the existing defects are as follows: [0005] 1. The open coating process causes air pollution, and the waste of coati...

AI Technical Summary

Problems solved by technology

[0005] 1. The open coating process causes air pollution, and the waste of coating materials is large, which cannot be recycled;

[0006] 2. The required production workshop is relatively large;

[0007] 3. In the process of vertically fixing the coating pipe to the transmission system, it takes a lot of time, the work efficiency is low, and there is a high risk;

[0008] 4. During the coating process, due to the high center of gravity and large moment of inertia of the coating pipeline, it is easy to damage the equipment and even cause safety accidents;

[0009] 5. The transmission system is used to drive the coating pipeline weighing several tons to rotate at high speed, and the transmission system consumes a lot of energy;

[0010] 6. The length of the processing coating pipe is generally limited to less than 6m, and longer coating pipes cannot be processed;

[0011] 7. The system has a low degree of automation and cannot automatically complete the coating process for pipes of different specifications;

[0012] 8. It cannot be adjusted automatically to adapt to the coating of pipes of different specifications (pipe diameter, length)
