摘 要
本設(shè)計(jì)簡要地介紹了橋式起重機(jī)的發(fā)展?fàn)顩r、特點(diǎn)、組成、性能、結(jié)構(gòu)及起升機(jī)構(gòu)和小車運(yùn)行機(jī)構(gòu)的設(shè)計(jì)，并參照相關(guān)資料對起重機(jī)起升機(jī)構(gòu)及其零部件進(jìn)行設(shè)計(jì)計(jì)算，從方案論證到具體設(shè)計(jì)計(jì)算，充分發(fā)揮了計(jì)算機(jī)在整體設(shè)計(jì)中的作用，從而提高了設(shè)計(jì)質(zhì)量，縮短了設(shè)計(jì)周期，提高了工作效率。
首先在橋式起重機(jī)的起升機(jī)構(gòu)設(shè)計(jì)中，本設(shè)計(jì)從起升機(jī)構(gòu)的設(shè)計(jì)方案展開，在橋式起重機(jī)起升機(jī)構(gòu)設(shè)計(jì)方面，從鋼絲繩的選取及校核、卷筒選定、吊鉤的設(shè)計(jì)、吊鉤橫軸確定、電機(jī)、減速器和制動(dòng)器的選取及相關(guān)校核這幾方面進(jìn)行了設(shè)計(jì)計(jì)算。在小車運(yùn)行機(jī)構(gòu)的設(shè)計(jì)計(jì)算中我們從起重機(jī)整體出發(fā)，由受力計(jì)算，車輪選取，電機(jī)及減速器選定校核和浮動(dòng)軸的設(shè)計(jì)構(gòu)成。

Abstract
The design brief introduction of the overhead crane state of development, characteristics, composition, performance, structure, and the lifting mechanism and operation of the trolley design, and in the light of relevant information on the crane and its components or design, from the feasibility study to the specific program design, make full use of computers in the overall design, thereby improving the design quality and shorten the design cycle, improve work efficiency.
First in the overhead crane hoisting mechanism design, the design of hoisting bodies from the design program launched the bridge crane hoisting mechanism design, selected from the rope and Verification, selected reel, hook design, determine horizontal hook, motor, brake and reducer selection and related Check these aspects of design. Trolley operation in the design calculations from the crane overall, by force, wheel selection, motor and reducer selected Checking and floating axis constitutes the design.
Keywords: Overhead crane; Hoisting mechanism; Traverse mechanism; Design
