The invention discloses a crane support based on mortise and tenon connection. The crane support comprises an outer frame, a bottom frame, tail reinforcing ribs and connecting pipes. The outer frame is of a shell structure with an opening in the bottom. The two side walls of the rear portion of the outer frame are connected through a connecting pipe, and a tail reinforcing rib is installed at the rear end of the outer frame. Dovetail mortises are arranged at the bottoms of the two side walls of the outer frame. The bottom frame comprises a bottom beam, a front reinforcing plate, a middle reinforcing plate and a side reinforcing plate are arranged on the bottom beam, and the front reinforcing plate, the middle reinforcing plate and the side reinforcing plate are respectively connected with the outer frame through mortise and tenon structures. The parts are mainly connected in a mortise and tenon joint welding mode, direct stress of a pure welding structure and a welding seam is avoided, the redundancy of structural design is reduced, the reliability of the structure is improved, and the light weight level is improved.
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。
