Automatic rust removal spraying system and method for turnout steel rail

Abstract

The invention relates to an automatic rust removal and spraying system and method for a turnout steel rail. The system comprises a conveying line, a saw steel rail surface rust removal shot blasting machine, a surface cleaning device, a paint spraying room, a drying room, a waste gas treatment device, a steel rail transplanting mechanism and a discharging mechanism. The method comprises the steps that (1) a steel rail workpiece is placed on a feeding conveying line; (2) the steel rail is conveyed into a saw steel rail surface rust removal shot blasting machine to be subjected to shot blasting and rust removal treatment; (3) conveying into a surface cleaning device for deep cleaning through a surface derusting and cleaning conveying line; (4) carrying into a paint spraying room for paint spraying; (5) the steel rail workpieces are conveyed into a drying room to be dried, and then the dried steel rail workpieces are conveyed to a discharging conveying line through a steel rail transplanting mechanism; and (6) discharging by a discharging mechanism. Rapid rust removal and full-section coating of the surface of the steel rail can be achieved, the derusted steel rail can reach a certain degree of finish, the good rust removal effect is achieved, the coating requirement of the steel rail is met, and the coated steel rail can reach a certain anti-corrosion effect and meet the technological requirement.

Description

technical field [0001] The invention relates to the technical field of derusting and spraying of turnout rails, in particular to an automatic derusting and spraying system and method for turnout rails. Background technique [0002] Rail is one of the most critical parts of turnout, and its product quality determines the safety level of the railway. Every year in the material department of the engineering department, turnout rails of different degrees are stored in the open air at the construction site for a long time, and cannot be used normally due to serious corrosion. The company's open stock yard also faces the same problem, resulting in a lot of waste. In the face of increasingly fierce market competition, it is necessary to develop an automated rail surface pretreatment process to comprehensively improve the appearance quality of turnout products. [0003] Problems existing in surface anticorrosion of traditional turnout rails: [0004] The anti-corrosion method of t...
