AI Technical Summary
Technical Problem
The welded connections of existing crane supports are unstable and prone to fatigue cracks, which limits the vehicle's lightweighting level and results in insufficient safety.
Method used
The mortise and tenon joint method is used to replace the pure welding structure. The various parts are connected together through the mortise and tenon structure, avoiding the direct stress on the weld seam.
Benefits of technology
It improves the reliability and lightweighting of the crane support, reduces the redundancy in the structural design, and enhances safety.

Abstract
本发明公开了一种基于榫卯连接的吊机支座，包括外框架、底部框架、尾部加强筋和连接管；所述的外框架为底部开口的壳体结构；外框架的后部两侧壁之间通过连接管连接，外框架的后端安装有尾部加强筋；外框架两侧壁的底部设有燕尾卯头；所述的底部框架包括底梁，底梁上设有前部加强板、中部加强板及侧部加强板，前部加强板、中部加强板及侧部加强板分别与外框架通过卯榫结构连接。本发明的各个零件之间的连接方式主要为榫卯焊接，避免了纯焊接结构和焊缝直接受力，降低了结构设计的冗余度，提高了结构的可靠性，提升了轻量化水平。
