1、河北工程大学毕业设计（论文）摘要ZMZ蟹爪式装煤机是一种全液压式装煤机，是一种集装载、运输、行走于一体的液压传动装载机械化设备，适用于港道断面尺寸（宽×高）≥1800×1400mm的煤矿企业的炮采采煤工作面和掘进工作面。特别适用于半岩巷掘进装运。可与矿车、刮板输送机、带式输送机等配套使用，亦可用于地面煤场的装载。本装煤机的装载能力为每小时一百立方米，装机功率为45千瓦。ZMZ蟹爪式装煤机行走灵活，可原地转弯，操作方便，运行平稳。其采煤和掘进效率高，使用安全。改进后的装载机，装载部机头架能起落，可实现铲板抬起高度324mm，铲板卧底深度213mm，装载部采用蟹爪式，工作时两蟹爪交替运动
2、，实现连续作业，运输部设有回转台，可实现转载机头的左右摆动角度±43º38，同时还设有升降液压缸，可实现转载机构的升降。通过试验表明：ZMZ蟹爪式装煤机设计合理，电气、液压系统性能稳定可靠，适应性强，并具备操作简单，故障率低等优点。关键字：ZMZ蟹爪式装煤机液压行走灵活改进安全-I-I河北工程大学毕业设计（论文）AbstractZMZcrabclawtypepackisaspeciesoffullhydraulicpressureplow,isatypeofoutfitofplowintegratingloading,transportation,walkintheintegrati
