The invention belongs to the field of engineering machinery, and relates to a telescopic supporting leg lap joint structure and a concrete pump truck with the same. The telescopic supporting leg lap joint structure comprises supporting legs and an underframe lap joint area, the underframe lap joint area comprises an underframe box body and an underframe lap joint plate, and the underframe box bodycomprises underframe side plates, an underframe bottom plate and an underframe door plate; each supporting leg comprises a supporting leg box body, a supporting leg lap joint plate and a lap joint block; each supporting leg box body comprises a supporting leg cover plate, a supporting leg bottom plate and a supporting leg side plate; the supporting leg lap joint plates are arranged at the tail ends of the supporting legs, and the lap joint blocks are symmetrically arranged on the supporting leg side plates. According to the technical scheme, the strength and rigidity of the lap joint area canbe improved, meanwhile, lap joint of the side faces of the supporting legs is increased, lap joint sets are arranged in the upper, lower, left and right directions of the whole lap joint area, and the structural stability of the supporting legs bearing complex loads during pump truck supporting work is guaranteed.
本发明属于工程机械领域,涉及一种伸缩支腿搭接结构及具有该结构的混凝土泵车,所述伸缩支腿搭接结构包括支腿和底架搭接区域,所述底架搭接区域包括底架箱体和底架搭接板,所述底架箱体包括底架侧板、底架底板、底架门板;所述支腿包括支腿箱体、支腿搭接板和搭接块;所述支腿箱体包括支腿盖板,支腿底板,支腿侧板;所述支腿末端设置有支腿搭接板,所述支腿侧板上对称设置有搭接块。本发明的技术方案可以提高搭接区域的强度和刚度,同时增加支腿侧面搭接,使整个搭接区域上下左右四个方向均设有搭接组,保证了泵车支撑工作时支腿承受复杂载荷时结构的稳定性。
