Problems solved by technology

[0005] At present, conventional dirt-repellent coatings are mainly organic silicon, organic fluorosilicon and fluorocarbon coatings, which have certain insulation properties. The use of these coatings in catenary components will affect the electrical conductivity of the catenary, and are suitable for high-speed rail contact The dirt-repellent coating required for the use of grid components must also have electrical conductivity, and there is no related coating technology and product at present

Abstract

The invention discloses a catenary steel wrist arm positioning device coated with a dirt-repelling composite coating and a processing method, which is characterized in that: the outer surface of the bottom anti-corrosion coating of some or all parts is coated with a dirt-repelling composite coating, The dirt-repellent composite coating is an anti-corrosion conductive dirt-repellent paint. The catenary steel wrist arm positioning device of the present invention has low manufacturing cost, and the long-term anti-corrosion coating and the dirt-repellent composite coating have a good anti-corrosion effect, which can effectively avoid or reduce the adhesion of corrosive dirt such as dust, and greatly improve the anti-corrosion effect. The life and operation safety and reliability of the new steel wrist arm positioning device are guaranteed.

Description

Technical field [0001] The present invention belongs to the field of electrified railway contact net steel wrist arm, and specifically, a contact mesh steel wrist arm positioning device and a processing method coated with an antifouling composite coating. Background technique [0002] The rail transit high-speed railway is an important part of my country's transportation hub. Among them, the eastern coastal cities, while near sea marine salt fog, severe polluting industrial atmosphere, dust, etc., the corrosion resistance and service life of high-speed rail equipment under the harsh environmental conditions. Higher requirements. In particular, the steel wrist arm positioning device serves as a high-speed rail electrified facility, and the corrosion of saline and adhesive dirt directly affects the operating safety and operating cost of high-speed rail. [0003] A conventional steel wrist arm positioning device is often prepared to prepare an anticorrosive coating surface on its ma...
