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
2、两蟹爪交替运动,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V-V-河北工程大学毕业设计(论文)AbstractZMZcrabclawtypepackisaspeciesoffullhydraulicpressureplow,isatypeofoutfitofplowintegratingloading,transportation,walk
