5噸LD型電動單梁橋式起重機的設計
摘 要
我做的畢業(yè)設計課題是單梁橋式起重機設計。單梁橋式起重機是一種輕型起重設備，它適用起重量為1～20 噸，適用跨度4.5～16.5米，工作環(huán)境溫度在≥-35。C與≤+35。C范圍內，適合于車間、倉庫、露天堆場等處的物品裝卸工作。橋架由一根主梁和兩根端梁剛接組成。根據起重量和跨度，主梁采用普通工字鋼和U形槽組合焊接形成。主梁和端梁之間采用承載突緣普通螺栓法蘭連接。提升機構采用CD型電葫蘆。
此次設計的主要內容有：問題的提出、總體方案的構思，結構設計及對未知問題的探索和解決方案的初步設計，裝配圖、零件圖等一系列圖紙的設計與繪制，以及畢業(yè)設計說明書的完成。
關鍵詞 ：起重機；橋式起重機；大車運行機構；小車運行結構；小車起升；結構橋架；主端梁 。
ABSTRACT
The topic of my graduation design is list the beam bridge type derrick of design the list beam bridge type derrick is a kind of light heavy equipments, it start to apply the weight as 1~20 tons, apply to across degree 4.5~16.5 meters, the work environment temperature is in the ≥ -35.C and ≤ +35.Inside scope, suitable for car, warehouse, open-air heap field etc. of the product pack to unload a work. The bridge was carried beam by a lord beam and 2 to just connect to constitute. According to weight with across a degree, lord beam adoption common the work word steel and U form slot combination weld formation. Lord beam and carry an of beam an adoption loading To good luck common stud bolt method orchid conjunction. Promote the organization adoption CD type an electricity bottle gourd.
The main contents of this time design have: The problem put forward, conceive outline of total project, possibility design, structure design and draw towards doing not know a problem of investigate and solution of first step design, assemble diagram, spare parts diagram wait a series the design of the diagram paper with, end include graduation design manual of completion.
Keywords: cranes;bridge type derrick ； During operation organization; Car running structure; Car hoisting structure; Bridge; Main girders.
