The invention relates to the technical field of pump truck auxiliary equipment, in particular to an auxiliary supporting leg structure for a concrete pump truck. Comprising a concrete pump truck, two horizontal frame longitudinal beams in the length direction of the concrete pump truck are fixedly installed at the bottom of a frame of the concrete pump truck, at least two vertical rotating shaft parts in the length direction of the frame longitudinal beams are arranged on the lower portion of each frame longitudinal beam, supporting rods are installed on the lower portions of the vertical rotating shaft parts in a hinged mode, and balance weight supporting feet are installed at the free ends of the supporting rods in a hinged mode. The vertical rotating shaft parts of the two frame longitudinal beams are in one-to-one correspondence, the frame longitudinal beams are provided with first power assemblies for driving the vertical rotating shaft parts to rotate corresponding to the vertical rotating shaft parts, and the vertical rotating shaft parts are provided with second power assemblies for driving the corresponding supporting rods to rotate along hinge shafts; the mode that the inclined supporting rods are installed between the frame longitudinal beam and the balance weight supporting feet in a hinged mode is adopted, torsional force generated on the frame longitudinal beam during construction of the concrete pump truck is effectively decomposed and counteracted, the frame longitudinal beam is effectively protected, and the service life of the frame longitudinal beam is prolonged.

    本发明涉及泵车辅助设备技术领域,具体涉及一种用于混凝土泵车的辅助支腿结构;包括混凝土泵车,混凝土泵车的车架底部固定安装有两根呈沿其长度方向的水平的车架纵梁,每根车架纵梁下部均设有至少两个沿其长度方向的竖向转轴部,竖向转轴部下部均铰接安装有支撑杆,支撑杆的自由端均铰接安装有配重支脚,两根车架纵梁的竖向转轴部一一对应,车架纵梁对应每个竖向转轴部均设有驱动其转动的第一动力组件,竖向转轴部均设有驱动其对应的支撑杆沿铰接轴转动的第二动力组件;本发明采用在车架纵梁与配重支脚之间铰接安装斜向的支撑杆的方式,有效的分解抵消混凝土泵车施工时对车架纵梁产生的扭转力,对车架纵梁进行有效保护,提升其使用寿命。
