900t移梁机吊具设计与优化

Design and Optimization of 900t Beam Spreader

本文对已有的900t移梁机双线梁吊具进行分析,阐述了吊具存在的吊取范围小、变换吊杆位置不方便等问题。提出了通孔式吊具的方法,并将其应用于单线梁的吊取,再通过对吊具进行相应的计算和有限元分析,验证了此方法在不影响安全的情况下,进一步提高其适用范围的可行性,望本文可以对类似的改良设计提供参考。

This paper analyzes the two-wire beam spreader of existing 900 t beam-shifting machine, and expounds the problems of small lifting range and inconvenient change of the boom. The method of through-hole spreader is put forward and applied to the lifting of single-line beam. Then the corresponding calculation and finite element analysis of the spreader are carried out to verify that the method can further improve the feasibility of the scope of application without affecting safety, to provide a reference for similar improved design.
