Railway Freight Car Coupler Buffer Device Maintenance Line Of Research

Railway freight car coupler buffer device as one of the most important components in vehicles, directly affect the safe operation of the railway freight car. Only in special field in time of coupler buffer device overhaul, to better safeguard, maintain or even improve performance of coupler buffer device, ensure its function and role play effectively. Therefore, it is necessary to design and build high performance, fully functional coupling buffer device maintenance process line, to meet the requirements of coupler buffer device repair technology.In this paper, by adopting case study method, experience summary method, field survey method, literature research method, exploratory studies and other research methods, the implementation of theoretical knowledge research and equipment using the combining research, literature review, in-depth research and analysis, scientific and rational policy, clear optimization idea. From there search and analysis Chinese Railway General Company requirements for coupler buffer device maintenance process to start, analysis of coupler, buffer, hook tail frame, hook, hook tongue lock, lock pin coupler iron, composition, hook tongue pin, hook tail spin and other accessories mamtenance the main process flow, technical requirements and main process equipment required. Jiang’ an vehicle maintenance coupler buffer device technology to built in 2010 and put into use as a case study, in-depth field investigation, consulting the relevant design drawings and other technical information, the scene investigation to understand the performance of the equipment and equipment use, maintenance of state meets the management and other aspects of the problems and difficulties, Analysis this coupler buffer device repair technology line of design, construction and use of the main problems and need to improve the optimization.In this paper, in strict accordance with the relevant Chinese railway corporation coupler buffer device repair technology standards and requirements, in order to realize the process of science, mechanical transmission, automatic detection, intelligent control, maintenance, easy management; to text, safe environmental protection "as the goal, outstanding solution to repair site space is narrow, few conveyor line bypass channel is not considerate, too long, equipment maintenance, the intelligent detection control ability is not strong, lack of security, environmental protection, such as insufficient ideal, coupler buffer device maintenance optimization design process line, a reasonable increase plant span, satisfy the hook check-up conveyor line, buffer conveyor line, hook tail box maintenance repair conveyor line, hook tongue inspection conveyor line of four" mainline "tied for layout, reasonable process flow science needs; Add underground conveyor line maintenance channel, easy to maintenance and management of underground conveying line; In shot blasting derusting outside design with acoustic noise reduction, dust removal environmental protection facilities, to further satisfy the security requirements of environmental protection; Explore to establish intelligent detection, automatic control equipment, enhance the capacity of intelligent test control, cogent accomplish "with tooling process, in order to process quality, quality safety", to the coupler buffer device maintenance process line to offer reference to the design, construction, security coupler buffer device maintenance quality conforms to the standards and requirements, ensure the safety of railway freight train even hang.
