Discussion on Safety-brake Issues of Large Maintenance Machinery
Safety-brake is the common design in Large maintenance machinery industry.The purpose of the design is to prevent losing brake in case of sudden losing power in runtime.Safety brake is used to unlock the traveling signal and switch operation before running.While the function of increasing parking pressure is applied when the train parked.However the phenomenon of brake pressure accumulation and incomplete brake relief oc-curs occasionally after cutting off the safety-brake during unpowered traction.In response to this issue,this the-sis proceeds from the principle of pneumatic components to analyze the causes of the problem based on actual op-erating conditions.The targeted solutions are put forward and put into effected from the comparison between do-mestic and foreign design.The objective of the thesis is to explore the use of safety brake in large maintenance machinery and optimize design methods to improve design capabilities.
