摘要簡(jiǎn)易吊車，用于機(jī)械加工車間小范圍內(nèi)的搬運(yùn)和起吊，對(duì)機(jī)械車間來說，即使上小物件也有上百斤重甚至上千斤重，工人是無法搬運(yùn)和搬起的，此時(shí)，車間如果有一輛此種簡(jiǎn)易吊車，這種問題便迎刃而解了，它的使用，既不耽誤大吊車的工作，又解決了上述問題，可以提高車間的生產(chǎn)效率。簡(jiǎn)易吊車由電動(dòng)機(jī)經(jīng)帶傳動(dòng)和一對(duì)開式齒輪傳動(dòng)，將運(yùn)動(dòng)和動(dòng)力傳給卷筒，再通過鋼絲繩和滑輪組提升重物。其工作機(jī)構(gòu)包括卷筒、鋼絲繩和滑輪組。傳動(dòng)機(jī)構(gòu)包括電動(dòng)機(jī)、帶輪、齒輪和軸。因起吊時(shí)物件需要在空中停留故需要設(shè)計(jì)一制動(dòng)裝置。提升或降低物件是靠電動(dòng)機(jī)的正反轉(zhuǎn)，使物件停留在空中是靠制動(dòng)裝置的。對(duì)原始數(shù)據(jù)和工作原理進(jìn)行分析，確定出大致的傳動(dòng)方案。根據(jù)大致的傳動(dòng)方案圖確定所要設(shè)計(jì)的部分有工作機(jī)構(gòu)、傳動(dòng)機(jī)構(gòu)、制動(dòng)裝置、機(jī)架等，然后查閱相關(guān)資料對(duì)其進(jìn)行計(jì)算和校核.因其為手推式移動(dòng)吊車，故要求小吊車要有很高的靈活性，在此，把小吊車的兩后輪設(shè)計(jì)為萬向輪，可以在任意方向運(yùn)動(dòng)。對(duì)小吊車整體要求是工作時(shí)穩(wěn)定可靠，故設(shè)計(jì)完成后要對(duì)小吊車的整體穩(wěn)定性進(jìn)行分析和校核，力求穩(wěn)定、安全、可靠。關(guān)鍵詞：電動(dòng)機(jī)； 卷筒； 齒輪； 滑輪組； 軸IABSTRACTSimple 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 verification to stability, security and reliable.
