目的 设计适用于大扩展比车载医疗方舱的自动支撑调平系统,填补医疗设备的空白区域.方法 通过对国内外各种车载方舱扩展调平系统的调研分析,掌握现有各类车载方舱扩展调平系统的特点及局限性,利用电控新技术设计一款区别以往液压式四点调平支撑调平机构,以满足大扩展比车载医疗方舱对支撑调平系统的需求.结果 设计出具有电控滑道和多级电控支腿自动调平系统方案,并成功运用在车载医疗方舱上使用,工作性能表现优越,工作能源环保清洁,环境适用性强,使大扩展比车载医疗方舱在各种复杂地理和环境下的都能够快速支撑调平,顺利扩展及撤收.结论 大扩展比车载医疗方舱自动支撑调平系统更大程度上改进了车载医疗方舱的稳定性、安全性,更大限度的发挥医疗方舱在重大灾害救援现场大批量伤员面临医疗救治的作用.%Objective The study aimed to design a support automatic leveling system for large expansion vehicle medical shelter, to fill the blank area of medical equipment. Methods The characteristics and limitations of the existing various types of car shelter expansion and leveling system were evaluated through a variety of domestic and international vehicle cabin investigation and analysis of expansion and leveling system. In order to meet the needs of adjustable support vehicle medical shelter for large expansion ratio, we used a new electrical technologies to design a leveling system, which is different from previous hydraulic four point leveling mechanism. Results We designed an electronic slideway and multi-leg automatic leveling system. The system was successfully used in vehicle medical shelter with superior performance, clean energy, environmental protection and environmental adaptability. The large expansion vehicle medical shelter was also able to support fast leveling, smooth expansion and retraction in various complicated geographical and environment. Conclusion The vehicle automatic support leveling system can improve stability and safety of vehicle to a greater extent, which will play an important role for medical treatment of mass casualties in major disaster.
