橋式起重機橋架結(jié)構(gòu)設計
摘 要
橋式起重機主要由機械部分、金屬結(jié)構(gòu)和電氣三大部分所組成。機械部分是指起升、運行、變幅和旋轉(zhuǎn)等機構(gòu),還有起升機構(gòu),金屬結(jié)構(gòu)是構(gòu)成起重機械的軀體,是安裝各機構(gòu)和支托它們?nèi)恐亓康闹黧w部分。電氣是起重機械動作的能源,各機構(gòu)都是單獨驅(qū)動的。
構(gòu)成橋式起重機的主要金屬結(jié)構(gòu)部分是橋架,它橫架在車間兩側(cè)吊車梁的軌道上,并沿軌道前后運行。本文根據(jù)橋式起重機起重量和跨度的要求,依據(jù)《起重機設計規(guī)范》、GB/T3811-2008等標準,設計計算了50/10t×25.5m偏軌雙梁橋式起重機橋架結(jié)構(gòu)的設計方案,并繪制了相關(guān)的三維結(jié)構(gòu)圖以及二維結(jié)構(gòu)圖。
本文首先從整體設計出發(fā),依次設計計算了50/10t×25.5m雙梁橋式起重機的主端梁結(jié)構(gòu)的主要機構(gòu)部件。選取了大車車輪,小車車輪,小車軌道等起重機主要零部件。設計了符合經(jīng)濟梁要求的橋架結(jié)構(gòu),并校核了起重機橋架在危險截面處的強度和剛度等力學性能參數(shù)。設計過程中,橋架采用全偏軌箱形主梁、箱形端梁的雙梁結(jié)構(gòu)。橋架剛性好,制作方便。考慮到起重機整機和各個機構(gòu)零部件的合理布置,作者通過計算多組數(shù)據(jù)來選擇最優(yōu)結(jié)果。達到了起重機各機構(gòu)布置緊湊性和合理性的目的,從而優(yōu)化了起重機整機的性能。
本設計所選的大部分零件均具有通用化、標準化、系列化的特點,主要技術(shù)參數(shù)均符合ISO標準,貫徹了國家以及起重機行業(yè)的所有最新頒布的各項標準。所設計的起重機整體安全、可靠。

The design of the structure of bridge crane
Abstract
Because the crane running at high altitude, scope of work can sweep the whole plant construction area, has a very important and irreplaceable role. Therefore welcomed by users, has been great development.
Bridge crane is mainly composed of the mechanical parts, metal structure and electrical three parts. The mechanical part is lifting, running, amplitude and rotating mechanism, metal structure is composed of lifting body, is the main installation of various institutions and support them all the weight of the part. Electric is a lifting movement of energy, the agencies are separately driven.
Constitute the main bridge crane metal structure part is the bridge, it is in the workshop crane beam transverse frame on both sides of the track, and along the track before and after operation. According to the requirements of the bidding documents of an enterprise and the design specification of crane GB/T3811-2008, performance evaluations of 50/10t×25.5m double beam bridge crane were calculated, and draw the three-dimensional structure and two-dimensional structure diagram.
At the beginning of this article, the main structure of 50/10t×25.5m double beam bridge crane were calculated. Select the carts wheels, trolley wheels, trolley tracks and other major components cranes.The structure of the bridge was designed to achieve the requirement of economical efficiency, and also intensity and stiffness was checked to make sure its safety. The double beam bridge structure includes the Crane Girder and the end carriage. This kind of structure has better stiffness and manufacturability. Considering the disposal of crane and different parts, the authors calculated through multiple data to select the optimal results. Finally, the goal of better crane performance and rationality and compactedness of all parts of crane was achieved.
At last, most of the parts of the design characteristics of the selected are universal, standardized, serialized, the main technical parameters are in accordance with ISO standard, implement the state and all the latest promulgated crane industry standards. In one words, the safety and reliability of this Crane can be confirmed.
