摘 要
采集程序
目前使用的重型自卸车由于载重量大，工作路况的复杂，加之所载矿砂的粘度、湿度较大，在车厢举倾时，矿砂经常不能完全从车厢中流出，使车厢重心发生偏移。当在有一定坡度的路面上卸货时，自卸车便可能发生侧翻。为了解决这个问题,本课题首先通过分析明确自卸车发生侧翻的前提条件，然后在车厢下底盘后横梁上固定一对由液压系统控制的支腿。当车厢举倾之前，此液压系统开始工作，通过液压缸推动支腿支承地面，防止自卸车侧翻。根据工作要求计算出支腿的支撑力以及相关性能参数，选择液压缸、液压泵、单向阀、溢流阀、调速阀、电磁换向阀等液压元件，完成支撑系统的液压原理图，并画出支撑系统与自卸车的装配图。
为了使结构简单，减少系统泄漏，提高稳定性。本设计中采用集成块，将各阀集成在一个油路板上。道路交通事故现场图

Abstract
消防快速接头
The heavy type dumper is over weight vehicle. It often runs on the complicated road surface. Because its freight such as silt, ore is sticky, the freight can not be dumped completely when the carriage is lifted. The remainder is glued to the carriage, so the gravity center of carriage will have an offset. When the dumper dumps freight on the certain slope road surface, the carriage will be likely to roll. For solving this problem, the roll precondition is analyzed firstly in this subject matter, then a pair of landing legs controlled by hydraulic system is fixed in the rear cross beam of chassis mainframe. 真空采血器This hydraulic system begins to wok before the carriage is lifted, then hydraulic cylinder drives landing legs to support road surface to protect rolling. 智能化信报箱According to its request, the holding power of landing legs can be calculated, then hydraulic cylinder, hydraulic pump, check valve, speed control valve and magnetic exchange valve and so on also can be choosed, and that hydraulic schematic diagram of support system and assembly diagram of support system and dumper can be accomplished.
In order to make structure simple, decrease leak, improve stabilization, integrated package is adopted in this design. Sorts of valves can be integrated in an oil road packag
