Automatic winding device used for external anti-corrosion glass fiber cloth of pipeline

Abstract

The invention belongs to the technical field of industrial production equipment, and relates to an automatic winding device used for external anti-corrosion glass fiber cloth of a pipeline. A first frequency converter and a second frequency converter which are electrically connected with a PLC are installed in a control cabinet. The first frequency converter and the second frequency converter are connected to control an axial motor and a radial motor. A material barrel and cloth under winding sleeve the axial motor. The pipeline under winding sleeves the radial motor. A first rotary encoder is connected between the axial motor and the PLC. A second rotary encoder is connected between the radial motor and the PLC. A touch screen, a return switch and an operation switch are arranged on the control cabinet. The axial motor is fixedly provided with the material barrel. The position, which is corresponding to the cloth under winding, of the material barrel is provided with a spraying port. The internal part and the bottom part of the material barrel are respectively provided with a temperature sensor and a heater which are communicated with the PLC. The start point and the end point of the pipeline under winding are provided with a first limit switch and a second limit switch. The device is scientific in design, reasonable in structure, easy to operate and convenient to use.

Description

Technical field: [0001] The invention belongs to the technical field of industrial production equipment, and relates to an automatic winding control device, in particular to an automatic winding device for anti-corrosion glass fiber cloth outside a pipeline, which has the characteristics of high degree of automation and good winding effect. Background technique: [0002] Pipeline anticorrosion refers to measures to slow down or prevent pipelines from being corroded and deteriorated under the chemical and electrochemical action of internal and external media or by the metabolic activities of microorganisms; in actual production and life, pipelines transporting oil, gas, water and other substances are mostly in In the complex soil environment, the conveyed medium is also corrosive, so the inner and outer walls of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause oil, gas, water, etc. to leak, which will not only interrupt the transportati...

Problems solved by technology

In practice, the more common way to coat large-diameter underground pipelines is to use anti-corrosion glass fiber cloth with asphalt, coal tar enamel paint or epoxy powder to form cold-wound tapes, and wrap them outside the pipelines to protect the metal. The role of the pipeline, the operation method in the prior art is mostly manual operation, that is, the workers manually apply asphalt, coal tar enamel paint or epoxy powder and other substances on the glass fiber cloth to form an anti-corrosion fiber cloth, and then manually wind it on the pipeline. This method not only has high work intensity and low efficiency, but it is also difficult to ensure that asphalt, coal tar enamel paint or epoxy powder are evenly applied, and it is also difficult to achieve uniform and tight winding of anti-corrosion fiber cloth. In addition, there are also workers' skin The problem of being stabbed when touching the scattered fiber filaments on the glass fiber cloth, or being scalded when touching the asphalt, etc. Therefore, the present invention designs an automatic winding device and method specially applied to the anti-corrosion glass fiber cloth outside the pipeline, which can Effectively reduce the labor intensity of workers, improve the quality of tape winding and anticorrosion, and have good application value and practical benefits
