摘　　要：针对传统管道水力输送的不足,提出了一种新型的节能环保运输方式:筒装料管道水力输送.管道车是此种输送方式的核心部件之一.采用理论分析与模型试验相结合的研究方法,对管道车的受力特点进行了分析,并探讨了不同型号的管道车在管道中运移的水力特性.结果表明,管道车的结构形式对其运行速度和输送能耗都有重要影响;型号为150 mm×80 mm的管道车运行速度和输送能耗都最大,型号为100 mm×80 mm的管道车次之,而型号为150 mm×70 mm的管道车最小.研究成果为进一步改进管道车结构提供了借鉴.In order to solve the problems of traditional piped hydraulic transportation,a new technique of energy conservation and environmental protection—the piped hydraulic transportation of tube-contained raw material was put forward.The piped carriage was one of the key parts of the technique.By a combination of theoretical analysis and model experiments,the stressed characteristics of the piped carriages were analyzed and hydraulic characteristics of the transportation of different types of piped carriages in the pipe were researched.The research results show that the structural form of the piped carriage has a significant influence on the motion speed and transport energy consumption.The motion speed and transport energy consumption are the largest for the 150 mm×80 mm piped carriage,take the second place for the 100 mm×80 mm piped carriage,and are the smallest for the 150 mm×70 mm piped carriage.These conclusions can be used as reference for further improvement on the structure of the piped carriage.
