摘要摘要 简易吊车，用于机械加工车间小范围内的搬运和起吊，对机械车间来说，即使 上小物件也有上百斤重甚至上千斤重，工人是无法搬运和搬起的，此时，车间如果 有一辆此种简易吊车，这种问题便迎刃而解了，它的使用，既不耽误大吊车的工作， 又解决了上述问题，可以提高车间的生产效率。简易吊车由电动机经带传动和一对 开式齿轮传动，将运动和动力传给卷筒，再通过钢丝绳和滑轮组提升重物。其工作 机构包括卷筒、钢丝绳和滑轮组。传动机构包括电动机、带轮、齿轮和轴。因起吊 时物件需要在空中停留故需要设计一制动装置。提升或降低物件是靠电动机的正反 转，使物件停留在空中是靠制动装置的。对原始数据和工作原理进行分析，确定出 大致的传动方案。根据大致的传动方案图确定所要设计的部分有工作机构、传动机 构、制动装置、机架等，然后查阅相关资料对其进行计算和校核.因其为手推式移动 吊车，故要求小吊车要有很高的灵活性，在此，把小吊车的两后轮设计为万向轮， 可以在任意方向运动。对小吊车整体要求是工作时稳定可靠，故设计完成后要对小 吊车的整体稳定性进行分析和校核，力求稳定、安全、可靠。 关键词：电动机； 卷筒； 齿轮； 滑轮组； 轴 I ABSTRACT Simple cable car, used for machining workshop small range handling and lifting , and this time, the workshop if there is such a simple cable car, this problem is solved, and its use, does not delay the work of large cranes, but also to solve the above problems, can improve plant productivity. Summary by cable car from the motor and a belt drive transmission gear off, will be sports and power to the reel, and then through the rope and pulley upgrade the heavy group. Its work, including the drum, wire rope and pulley blocks. Transmission mechanism including motor、pulleys、and gear shaft. When lifting objects because of the need to stay in the air it needs a brake. Raise or lower the object is positive on the motor so that the object is to stay in the air brakes on. On the working principle of the original data and analysis, to determine the transmission program in general. Transmission scheme in accordance with general plans to be designed to identify some of the work of agencies, transmission, brakes, chassis, etc., and then access to relevant information and check their calculation. Because of their push for mobile cranes, and called for a small a very high flexibility of the cable car in the rear two small cranes designed to Caster, you can in any direction. The overall requirements for small cable car is stable and reliable work, so after the completion of the design to the overall stability of the small cable car to carry out the analysis and verificati
