Abstract

[0002] Pipeline insulation is a protective technology to prevent the pipeline transport medium from condensing or freezing. For general oil (gas) pipelines, the most common method is to add an insulation layer to the outside of the pipeline. Now the one-time method is widely used to produce the anti-corrosion pipe insulation foam layer, which uses an extruder to coaxially extrude the outer wall of the insulation foam layer on the outside of the anti-corrosion pipe, and at the same time fills the insulation material between the outer wall of the insulation foam layer and the anti-corrosion pipe. In order to ensure the continuity of the one-time production, for different sections of anti-corrosion pipes, the extruder uses a mandrel to connect the ends in advance, so that a continuous insulation foam layer is formed on the ends of the anti-corrosion pipes in different sections, and then the insulation foam layer at the ends of the anti-corrosion pipes is peeled off, and then the excess insulation foam layer is cut using a cutting machine. The existing cutting machine is usually rigidly connected when fixing the insulation pipe, which may cause the outer surface of the pipe to deform, and the vibration generated during cutting is easy to affect the processing accuracy when cutting the insulation foam layer, affecting the processing quality, and foam debris and dust are easily generated during cutting, which is not easy to clean and affects the respiratory health of the staff.

[0027] The working principles and beneficial effects of the above embodiments.
[0028] When in use, the pipe is passed through the first fixing seat 3, the second fixing seat 11 and the worm gear 14, and the first cylinder 5 is started to drive the connecting sleeve 6 to move, so that the two clamps 8 clamp the outer surface of the pipe, and the interior of the internal oil chamber 9 is filled with hydraulic oil.

A collecting barrel is placed below the debris discharge port 23, so that the foam debris and dust generated during cutting are blown into the collecting barrel to prevent the foam debris and dust from flying around and affecting the health of the staff, and also facilitate subsequent cleaning.
