摘　　要：拉板平衡梁作为履带起重机中调节拉板档距的关键部件,当前的结构形式存在重量重、拆装不便、工艺性差的问题。提出一种折弯焊接一体式拉板平衡梁,并提取该形式平衡梁最恶劣受力情况,通过局部计算、整级计算及整机试验等方式对新型平衡梁结构可行性进行验证。Pull plate balance beam is a key component of the crawler crane to adjust the pull plate span,and the current structural form has the problems of heavy weight,inconvenient assembly and disassembly and poor manufacturability.A bended and welded integrated pull plate balance beam is proposed,and the worst stress situation of this form of balance beam is selected to verify the feasibility of the new balance beam structure by means of local calculation,overall calculation and overall machine testing.
