Method for manufacturing electric pole through dry laying, weaving and winding vacuum forming

Abstract

The embodiment of the invention discloses a method for manufacturing an electric pole through dry laying, weaving and winding vacuum forming, and relates to the field of electric power and communication equipment manufacturing process. The method comprises the following steps: coating a chopped strand mat laying layer on the outer surface of a core mold; winding a first fiber rough yarn laying layer on the outer surface of the chopped strand mat laying layer; coating the outer surface of the first fiber rough yarn laying layer with a composite felt laying layer; winding a second fiber rough yarn laying layer on the outer surface of the composite felt laying layer; coating the outer surface of the second fiber rough yarn laying layer with a woven roving layer; and winding a third fiber rough yarn laying layer on the outer surface of the woven roving layer. According to the method for manufacturing the electric pole through dry laying, weaving, winding and vacuum forming, multi-layer cross laying can be achieved without being limited by angles, so that the method can meet the requirements of the electric pole for various properties such as compressive strength, tensile strength, bending strength and elasticity modulus in application; and the method has the advantages of simplicity and convenience in operation, high yield, low production cost and high production efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the field of electric power and communication equipment manufacturing technology, and in particular to a method for dry laying, weaving, and vacuum forming to manufacture electric poles. Background technique [0002] The utility pole is the space support body of the cable, which requires good insulation performance and support performance. With the improvement of people's living standards, electricity supply can almost spread to residential areas across the country, but there are still some remote villages that have not been able to popularize power grids. These remote villages are located in high mountains. Not only do they have no roads, but even small roads have to be climbed. If electric wires are to be installed, the transportation of electric poles is a big problem first. General utility poles are mostly made of steel bars and cement, which are too heavy and difficult to transport and install; the i...
