Hollow insulator assembling method

Abstract

The invention relates to a hollow insulator assembling method which comprises the following steps of firstly, preparing an insulating core rod inner cylinder with a silicon rubber umbrella cover, an end flange, a connecting screw rod, a connecting nut and a travelling crane which are required by assembly; brushing epoxy resin glue on the outer surfaces of the circumferences at the two sides of the insulating core rod inner cylinder; placing the end flange and the glued insulating core rod inner cylinder on a special assembly mold to wait for assembly; realizing the initial assembly of a hollow insulator through the cooperation of the travelling crane; and putting the initially assembled hollow insulator into a special drying device for drying through the cooperation of the travelling crane, so that the required assembled hollow insulator is obtained. The method has the advantages that the hollow insulator is pre-assembled through the cooperation of the special assembly mold, so that the two end flanges are locked and fixed until drying is finished; the accuracy of the positions of the two end flanges in the whole process is ensured, the one-to-one correspondence of the positions of the connecting holes in the two end flanges is ensured, and deviation is avoided.

Description

technical field [0001] The invention relates to the field of insulator assembly, in particular to a hollow insulator assembly method. Background technique [0002] The hollow composite insulator is composed of an insulating mandrel inner cylinder, a terminal flange, and a silicone rubber umbrella sleeve. The silicone rubber umbrella sleeve is formed by connecting more than two silicone rubber umbrella sleeve segments. The connection structure is a stepped lap joint structure, that is, the tail of the umbrella cover section completed in the previous process is a stepped front lap joint ring with an outer diameter smaller than the outer diameter of the umbrella cover section, and the front lap joint ring is coated with adhesive. The front section of the umbrella cover section completed in the latter processing is a rear lap ring whose inner diameter matches the lap ring, and the front lap ring and the rear lap ring are bonded and connected by an adhesive. Its lap joint struct...

Problems solved by technology

In the process of fixing the end flange and the inner cylinder of the insulating mandrel, in order to enhance the stability of the connection between the end flange and the inner cylinder of the insulating mandrel, a Epoxy resin is used for bonding and fixing, and in this process, a processing accuracy requirement is involved. It is necessary to correspond the connection holes on the two end flanges one by one. In order to achieve the above purpose, the assembly process During the process, when the operator puts the end flange on the inner cylinder of the insulating mandrel, he needs to align the connection holes on the two end flanges in advance, and the alignment process is usually performed by personnel. The way of visual observation, the alignment process needs to be adjusted many times, which is very troublesome, and because the subsequent epoxy resin needs to be dried and cured, that is, the insulator needs to be moved, this process will easily cause the end flange to rotate phenomenon, which affects the alignment of the connecting holes
