The invention discloses a supporting disc structure of a hydraulic supporting leg of construction machinery, and belongs to the technical field of construction machinery. The supporting disc structurecomprises a hydraulic oil cylinder. A ball hinge is fixed to one end of the bottom of the hydraulic oil cylinder, and a supporting disc is installed on the ball hinge in a matched mode. A plurality of evenly-distributed hydraulic springs are connected between the periphery of the supporting disc and the periphery of the bottom of the hydraulic oil cylinder. Oil cavities of the plurality of hydraulic springs are communicated; when the supporting disc is perpendicular to the axis of the hydraulic oil cylinder, an included angle of 5-10 degrees is formed between each hydraulic spring and the axis of the hydraulic oil cylinder, and the inclination directions of at least one pair of adjacent hydraulic springs are opposite. After the engineering machinery is transferred or the engineering machinery is in operation, when the angle of the supporting disc is changed due to ground change or operation gravity center change, the multiple hydraulic springs can correspondingly stretch out or draw back, due to the fact that the oil cavities of the hydraulic springs are communicated and equal in pressure, the hydraulic springs can apply the same force to the supporting disc, the supporting disc is stressed evenly, sideslip is prevented, and potential safety hazards during operation are eliminated.

    本发明公布一种建筑机械液压支腿的支撑盘结构,属于建筑机械技术领域。包括液压油缸,液压油缸缸底一端固定有球绞,球绞上配合安装有支撑盘;所述支撑盘周边与液压油缸缸底周边之间连接有多个均布的液压弹簧;多个所述液压弹簧的油腔连通;所述支撑盘与液压油缸轴线垂直时,液压弹簧与液压油缸轴线具有5°‑10°的夹角,至少一对相邻液压弹簧的倾斜方向相反。工程机械转移后或者作业中,由于地面改变或者作业重心改变造成支撑盘角度变化时,多个液压弹簧会相应的伸出或者缩回,由于液压弹簧油腔相通,压力相等,各个液压弹簧会给支撑盘一个相同的力,支撑盘受力均匀,防止侧滑,消除了作业时的安全隐患。
