Vertical double-split wire lifting hook clamp used for 220kV hot-line work and made of carbon fiber plate

Abstract

The invention provides a vertical double-split wire lifting hook clamp used for 220kV hot-line work and made of a carbon fiber plate. The clamp comprises an arm part, an upper wire guide hook, a lower wire guide hook and a connecting section which are integrally designed. The connecting section is used for connecting the upper wire guide hook with the lower wire guide hook. The clamp is made of the carbon fiber plate which comprises at least two carbon fiber cloth layers and at least one carbon fiber yarn layer. The carbon fiber yarn layers are located between every two carbon fiber cloth layers. The carbon fiber cloth layers are formed by interweaving longitudinal carbon fibers and transverse carbon fibers in a one-up and one-down mode. The longitudinal carbon fibers and the transverse carbon fibers are the same in fiber width. The carbon fiber yarn layers are formed by interweaving carbon fibers in a one-up and one-down bi-directional mode. The carbon fiber cloth layers and the carbon fiber layers are steeped with cementing agents. The clamp is high in durability and capable of being used in an environment with strong acid, alkali, salt and atmospheric corrosion, does not rust, and has the advantages of being high in fatigue resistance, resistant to wear and aging and the like.

Description

technical field [0001] The invention relates to a high-voltage live working tool, in particular to a carbon fiber board vertical double-split wire lifting hook fixture for 220kV live working. Background technique [0002] Since the birth of new China, my country's electric power industry has developed rapidly. Since the beginning of the 21st century, it has ranked second in the world, and the maintenance work of various voltage levels has increased greatly. The live work method has become an important method for power grid enterprises to effectively improve the reliability of power supply and meet the growing material and cultural needs of the country and the people. One of the technical means is widely used in China Southern Power Grid, and the great economic and social benefits it brings have been proven in practice. At present, the work tools, especially the clamps, are mostly made of metal materials such as steel and aluminum alloy, which is contrary to the needs of my ...
