1背景2009年5月,HXN5型机车在齐齐哈尔机务段投入运用,运输效率明显提升。为有效解决瓶颈区间通过能力限制,更好地发挥新型大功率机车优势,经充分论证和试验验证,确认了HXN5型机车担当补机的可行性。机车自动提钩技术改造是保障HXN5型机车综合运用效率提高的内容之一。2改造方案2.1总体方案自动提钩装置利用机车总风管压缩空气为动力,驱动气动风缸产生提升力,通过司机主动按压
1 Background In May 2009, the HXN5 locomotive was put into operation in the Qiqihar locomotive depot, and the transportation efficiency was obviously improved. In order to effectively solve the bottleneck through capacity constraints, to give full play to the advantages of new high-power locomotive, the full demonstration and experimental verification confirmed the feasibility of HXN5 locomotive as a fill machine. Automatic lifting of the locomotive technology innovation is to ensure the comprehensive utilization of HXN5 locomotive one of the elements to improve efficiency. 2 transformation program 2.1 The overall program Automatic lifting device using the locomotive total air duct compressed air as the driving force to drive the pneumatic cylinder to produce lifting force, through the driver’s initiative to press
