Novel device for automatically stripping anticorrosive coating of pipeline

Abstract

The invention discloses a novel device for automatically stripping an anticorrosive coating of a pipeline, which is mainly used for stripping the anticorrosive coating wrapped on the surface of the pipeline in the construction, maintenance and repair processes of the pipeline. The device mainly comprises a pipeline body, a pipeline coating, a heat insulation layer, a reflecting magnetic plate, a heating coil, a handle, a temperature measuring probe, a motor winding device, a temperature controller, a medium-frequency heating power supply, walking supporting wheels and a flexible shell. According to the working principle, power frequency electricity outputs 30Khz medium frequency electricity to the heating coil through the medium-frequency heating power supply to form a magnetic field, thenpenetrates through the pipeline coating through the front reflecting magnetic plate to form eddy current on the surface of the pipeline body to realize rapid heating, then softens the pipeline coating on the surface, and then realizes automatic separation of the pipeline coating and the pipeline body through a motor winding device so as to achieve the effect of automatic stripping. The device hasthe advantages of being reasonable in structure, convenient to use, safe, reliable, free of pollution to the environment and free of interference of external temperature.

Description

technical field [0001] The invention is a novel device for stripping anticorrosion coating of pipelines, and relates to the technical field of stripping anticorrosion coatings of pipelines in the process of construction, maintenance and emergency repair. Background technique [0002] In the process of existing pipeline construction, maintenance and rush repair, the main method is to use fire and grinding to peel off the anti-corrosion layer on the surface of the pipeline. This method has the following disadvantages: 1. The heating rate is slow, and construction cannot be carried out when there is a medium in the pipeline; 2. The safety factor is low; 3. The work efficiency is low; 4. The on-site construction environment is polluted. There is a need for further improvement in these. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a new type of device that can make the pip...
