摘要 翻车机是矿山常用的一种卸矿机械，原矿石由矿车编组运输至矿仓上方后，由翻车机卸入矿仓，随着采矿技术的发展和提高产量的需要，原设计的翻车机往往不能满足要求，FCJ-Ⅰ型型的自行式液压翻车机是一种新型的翻车机，它很好的解决了这一困难，生产实践表明，这种翻车机已成为重要的矿山生产设备。 FCJ-Ⅰ型型的自行式液压翻车机是为满足矿山的需要，根据原研制的FCJ-Ⅰ型的压翻车机在使用中的情况，根据需要研改制而成的，更便于生产，提高了生产效率，降低了工作强度。此次设计是仿制设计，基本上采用李洪平教授研制的液压翻车机样机的基本结构形式，结构和工作原理，通过对整机的结构了解，绘制整机装配图，在此基础上自主研制翻车机的液压系统设计，主要包括系统工作压力的确定，执行元件的控制确定，拟订液压系统原理图，计算执行元件主要参数，选择液压控制元件和辅件，绘制管路布置图和设计液压站。 通过本次设计，研究和计算，成功的完成了FCJ-Ⅰ型型的自行式液压翻车机上的液压系统设计。 关键词：液压翻车机，液压系统，原理，元件，参数。 Abstract The trippi
