雙柱式汽車舉升機(jī)設(shè)計

全套，有圖紙


摘  要

隨著我國汽車行業(yè)的蓬勃發(fā)展，汽車修理行業(yè)也迎來了巨大的市場需求。因此，汽修行業(yè)急需各種效率高、針對性強(qiáng)的汽修設(shè)備和工具。在汽修行業(yè)，雙柱托舉接觸車架式舉升機(jī)是一個被廣泛采納的舉升機(jī)。在最近幾年所有新銷售的舉升機(jī)中，至少三分之二都是這種類型的。本雙柱舉升機(jī)采用單液壓缸驅(qū)動，鋼絲繩實(shí)現(xiàn)雙柱同步舉升。
最大舉升質(zhì)量4000公斤，最大舉升高度1700毫米，符合汽車舉升機(jī)國家安全標(biāo)準(zhǔn)。通過正確的零件結(jié)構(gòu)設(shè)計圖紙及工藝要求，能夠方便的投入到生產(chǎn)。結(jié)構(gòu)緊湊、外形美觀，是一種高效率的汽修設(shè)備。

關(guān)鍵詞：雙柱托舉，同步舉升，舉升設(shè)備

ABSTRACT
With the great development of the automobile industry, automobile repair has been a large business. The business needs many kinds of equipment and tools which is effective and suitable. In the automobile repair industry, 2 post type is one of the most acceptable and useable kind. By the statistics of the sales about the hoist in these years, we found that almost 2/3 of the hoist market has been occupied by 2 post hoist. This time one cylinder is the drive kind of the 2 post hoist designed by me. It can make the two lifting arm in the same step by the steel wire. The max weight of the hoist is 4000kg and the max height of the hoist is 1700mm. The machine is fully accord with the China Hoist Safety Standard. With the accurately drawings and mature technics, it is easy to manufacture this kind hoist . And the device has a beautiful figuration and compact construction.

Key word:  2 post hoist ,  lifting in same step,  lifting equipment
