The invention relates to a supporting leg telescopic system, a hydraulic system, a supporting device and engineering machinery, the supporting leg telescopic system comprises a supporting leg assembly, and the supporting leg assembly comprises a box body which is in an arc shape; the supporting legs are arc-shaped and are movably embedded in the box body in the extending direction of the box body; the driving mechanism is configured to drive the supporting legs to be switched between the extending state and the retracting state; wherein in the extending state, the supporting legs are partially located outside the box body, and in the retracting state, the supporting legs are all located in the box body. According to the technical scheme, the supporting leg telescopic system can well adapt to an arc-shaped telescopic structure, the arc-shaped telescopic action is achieved, and the radius of an arc is not limited; the span of the telescopic supporting legs is large, and the span of a first-stage telescopic arc-shaped supporting leg can reach the span of a second-stage telescopic X-shaped supporting leg; the structure is simple, fault points are few, and reliability is high.

    本发明涉及一种支腿伸缩系统、液压系统、支撑装置及工程机械,其中,支腿伸缩系统包括:支腿组件,支腿组件包括:箱体,呈弧形;支腿,呈弧形,沿箱体的延伸方向可移动地嵌套于箱体内;和驱动机构,被配置为驱动支腿在伸出状态和收回状态之间切换;其中,在伸出状态下,支腿部分位于箱体外,在收回状态下,支腿全部位于箱体内。上述技术方案提供的支腿伸缩系统,能很好地适应弧形伸缩结构,实现弧线形伸缩动作,且对圆弧半径无限制;伸缩支腿跨距大,一级伸缩弧形支腿可以达到两级伸缩X支腿的跨距;结构简单,故障点少,可靠性高。
