Double-block type automatic spray coating system of sleeper prefabricated de-molding agent

Abstract

The invention provides a double-block type automatic spray coating system of a sleeper prefabricated de-molding agent and belongs to the technical field of production of railway engineering ballastless tracks. Aiming at solving the technical problems, the invention provides the double-block type automatic spray coating system of the sleeper prefabricated de-molding agent, which has the effects ofimproving the spray coating quality and shortening the spray coating time and has a good spray coating effect. The double-block type automatic spray coating system is characterized by comprising a pumping and discharging system, a spray coating system and an oil gas supplying system, wherein the pumping and discharging system comprises a sealed space composed of a sealing cover, a pumping and discharging pipeline, an exhaust fan set and an oil dirt filtering screen; the pumping and discharging system is used for pumping and discharging waste gas and waste materials, which are produced in a spray coating process of the de-molding agent, and filtering and discharging oil dirt out of a spray coating field; the spray coating system comprises a PLC (Programmable Logic Controller), a servo motorand a spraying gun; the spray coating system is used for spraying and coating the de-molding agent on a sleeper mold on a plane formed by two parallel longitudinal tracks along the movement of the servo motor; the oil gas supplying system comprises a gas pressure pump station, a storage tank and a diaphragm pump; the oil gas supplying system is used for providing the de-molding agent and air power to the spray coating system.

Description

technical field [0001] The invention relates to an automatic spraying system for a prefabricated release agent of a double-block sleeper, which belongs to the technical field of ballastless track production in railway engineering. Background technique [0002] At present, the most convenient and commonly used double-block sleeper release agent spraying in China is manual spraying. Due to the influence of the operator's quality awareness and work attitude, problems such as missed spraying, excessive spraying, and uneven spraying in some areas often occur. Inadequate spraying of the release agent affects the appearance quality of the double-block sleeper, and problems such as "mold sticking, peeling, and mottling" appear. In order to meet the needs of large-scale prefabrication of double-block sleepers, factory production, automation and high-quality products, the design optimization of the spraying of the release agent is required. It is necessary to improve the construction ...
