Description

Polyethylene thermal contraction patch laminating device Technical Field The utility model relates to the field of pipeline repairing equipment, in particular to a polyethylene heat shrinkage patch laminating device. Background In the transportation process of petroleum, natural gas and other pipelines, the surface of the pipeline is often damaged due to various reasons. The polyethylene thermal shrinkage patch has good corrosion resistance, insulativity and mechanical property, and is a common material for repairing pipelines. When the artificial bonding is performed, the spray gun is taken firstly to heat the patch and then closely bond the patch with the surface of the pipeline, then an operator performs rolling extrusion on the patch through the roller, and the patch is intermittently heated in a matching manner, so that the patch is closely bonded on the surface of the pipeline, and the connection between the patch and the pipeline is prevented from being influenced by bubbles. However, when the pipe is repaired, the manual operation steps are complicated, when the repairing sheet is extruded by using the roller, the condition that the spray gun needs to be held and the roller is rolled by one hand exists, the operation steps are complicated, and the working efficiency is reduced. Therefore, there is a need to provide a polyethylene heat-shrinkable patch applicator that solves the above-mentioned problems. Disclosure of utility model The utility model provides a polyethylene thermal shrinkage patch laminating device, which solves the problems of complicated manual operation steps and reduced working efficiency during patch-up of a pipeline.
