Abstract

The invention provides a composite insulator umbrella skirt cutting and core rod residual sheath grinding device and a using method. The insulator device comprises an insulator supporting structure used for clamping and supporting insulator hardware to be cut. A first power device used for driving the insulator hardware to rotate is installed on the side face of the insulator supporting structure,and a tool feeding mechanism used for cutting an umbrella skirt used for driving the insulator hardware is installed on the other side face of the insulator supporting structure. The side face of thetool feeding mechanism is provided with a coarse friction and abrasion disengaging machine used for conducting preliminary grinding on the insulator hardware, and the side face of the coarse frictionand abrasion disengaging machine is provided with a fine friction and abrasion disengaging machine used for conducting fine grinding on the insulator hardware. The device and the method have relatively high practical significance for separating large and small umbrella skirts of the composite insulator and a core rod sheath. Therefore, the large and small umbrella skirts and the core rod sheath of the composite insulator can be efficiently removed, an independent insulator core rod is obtained, and the mechanical property of the insulator core rod is further studied.

Description

technical field [0001] The invention relates to the field of removing sheds of insulators and mandrel sheaths, in particular to a device for cutting sheds of different sizes and removing sheds of mandrel rods for composite insulators and a method for using them. Background technique [0002] An insulator is a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. Therefore, composite insulator...
