平顶山工业职业技术学院毕业设计说明书（论文）1.5 吨型手拉起重葫芦设计摘 要起重机械是减轻笨重体力劳动，提高作业效率、实现安全生产的起重运输设备。在国民经济各部门的物资生产和物资流通中，手拉葫芦作为关键的工艺设备或重要的辅助机械，应用十分广泛。一个完整的作业循环一般包括取物、起升、平移、卸载，然后返回原处等环节。经常起动、制动、正向和反向运动是起重机械手拉葫芦的基本特点。手拉葫芦的设计和使用应符合 GB3811《起重机设计规范》和 GB6067《起重机安全规程》的规定。此次设计的手拉葫芦是吊装起重物在 1.5 吨左右，运用一整套 II 级齿轮减速传动，手拉葫芦主要用在工厂、矿山、建筑工地、码头、船坞、仓库或者在没电的情况下施工的场合，原动力靠人工是手拉力来传动，减小手拉力，增大齿轮啮合传动比，使结构紧凑美观，经济耐用是设计的目的。手拉葫芦是通过拽动手动链条、手链轮转动，将摩擦片棘轮、制动器座压成一体共同旋转，五齿长轴便转动片齿轮、齿短轴和花键孔齿轮带动起重链轮，由起重链轮带动起重链条吊起重物。关键字：起重机械，手拉葫芦，起动，制动，齿轮减速传动I平顶山工业职业技术学院毕业设计说明书（论文）ABSTRACTThe hoisting machinery is relieve heavy manual labor, improve working efficiency, realizesafe production of lifting transportation equipment. In national economic sectors of materialproduction and material circulation, hand hoist as key technological equipment or importantauxiliary machinery, application of very extensive. A complete homework circulation generallyincludes take things, hoisting, translation, unloading, and then returns to its place such links.Often starting, braking, forward and reverse movement is liftingtype hoists the basiccharacteristics of manipulator. Hand type hoists should comply with the design and use ofGB3811 the crane design code "and GB6067 the crane safety rules" regulation.The design of the hand in the gourd is lifting up around the clog 1.5 tons, using a set level IIgear transmission, and hand gourd basically use in factories, mines, const...
