摘 要
起重機(jī)是一種作循環(huán)、間歇運(yùn)動(dòng)的機(jī)械。本篇畢業(yè)設(shè)計(jì)為20/5t吊鉤橋式起重機(jī)的設(shè)計(jì)，主要用于車間及倉庫的起吊及搬運(yùn)貨物。該起重機(jī)主要是由大梁、起升裝置、端梁、大梁行走機(jī)構(gòu)、起升裝置行走機(jī)構(gòu)、軌道和電氣動(dòng)力、控制裝置等構(gòu)成。以間歇、重復(fù)工作方式，通過起重吊鉤或其它吊具的起升、下降，或升降與運(yùn)移重物。
本次設(shè)計(jì)的起重機(jī)工作特點(diǎn)是具有周期性：在每一工作循環(huán)中，它的主要機(jī)構(gòu)作一次正向及反向運(yùn)動(dòng)，每次循環(huán)包括物品的裝載及卸載，搬運(yùn)物品的工作行程和卸載后的空鉤回程，前后兩次裝載之間還有包括輔助準(zhǔn)備時(shí)間在內(nèi)的短暫停歇。

Abstract
Crane is a for loop, intermittent motion machinery. This school is designed to 20/5t hook bridge crane design, the main workshop and warehouse for lifting and transporting cargo. Mainly by the beam of the crane, lifting devices, side beams, girders running gear, running gear lifting device, track and electrical power, control devices and other accessories. Intermittent, repetitive work, through the lifting hook or other lifting spreader, down, or lift and transport heavy loads.
The design of the crane is characterized by cyclical: each work cycle, and its main body to conduct a forward and backward motion, each cycle including loading and unloading goods, transport and unloading of goods after the working stroke return an empty hook, there are between two consecutive loading, including auxiliary short preparation time, including stops.
