The invention relates to an arc-shaped two-stage telescopic concrete pump truck supporting leg structure, and belongs to the technical field of concrete pump truck supporting. The second-stage telescopic box is in sliding connection with the interior of the first-stage telescopic box, an outlet plate and a sliding block are welded to an outlet of the first-stage telescopic box from outside to inside, a telescopic hydraulic cylinder assembly is installed between the first-stage telescopic box and an upper cover plate of the second-stage telescopic box, and one end of the second-stage telescopic box is fixedly connected with a supporting hydraulic cylinder. The arc-shaped supporting leg has the advantages that the structure is novel, the arc-shaped supporting leg can be independent of the base structure and installed on the side of the base structure through the arc-shaped design, the number of stages of the arc-shaped supporting leg is small, the arc-shaped supporting leg has excellent ductility and space utilization rate along the vehicle body direction and the same span, and compared with other supporting legs, the arc-shaped supporting leg is larger in box body section size, higher in rigidity, higher in strength and higher in buckling stability. The vibration stability and the structural reliability of the whole vehicle are higher; and during working, movement is more stable and flexible, the requirement for a site is lower, and the site adaptability is higher.

    本发明涉及一种弧形二级伸缩式混凝土泵车支腿结构,属于混凝土泵车支撑技术领域。二级伸缩箱与一级伸缩箱内部滑动连接,一级伸缩箱出口处由外向内焊接有出口板与滑块,一级伸缩箱与二级伸缩箱上盖板之间安装有伸缩液压缸组件,二级伸缩箱一端固定连接支撑液压缸。优点是结构新颖,通过弧形的设计,可独立于底座结构,安装在底座结构的侧方,并沿着车身方向,同样跨距,弧形腿级数少,具有优越的延展性和空间使用率,弧形支腿相比其它型支腿的箱体截面尺寸更大,其刚度、强度、屈曲稳定性就更大,整车振动稳定性和结构可靠性更高;在工作时使运动更平稳和灵活,对场地要求更低,场地适应性更强。
