The invention relates to a multistage telescopic supporting leg system and engineering machinery, the supporting leg system comprises a frame (1), a first supporting leg (2), a second supporting leg (3), a first lead screw assembly (4) and a second lead screw assembly (5), the first supporting leg (2) and the second supporting leg (3) are movably installed on the frame (1), the first lead screw assembly (4) is configured to drive the first supporting leg (2) to move relative to the frame (1), and the second lead screw assembly (5) is configured to drive the second supporting leg (3) to move relative to the frame (1). The second lead screw assembly (5) is configured to drive the second supporting leg (3) to move relative to the frame (1), and the first lead screw assembly (4) and the second lead screw assembly (5) are matched with each other so that a driving piece in the first lead screw assembly (4) can drive a driving piece in the second lead screw assembly (5) to move. And the first lead screw assembly (4) drives the first supporting leg (2) to move and the second lead screw assembly (5) drives the second supporting leg (3) to move synchronously. The engineering machine comprises the multi-stage telescopic supporting leg system.

    本公开涉及一种多级伸缩支腿系统和工程机械,其中支腿系统包括车架(1)、第一支腿(2)、第二支腿(3)、第一丝杠组件(4)和第二丝杠组件(5),第一支腿(2)和第二支腿(3)分别可动地安装于车架(1)上,第一丝杠组件(4)被配置为驱动第一支腿(2)相对于车架(1)运动,第二丝杠组件(5)被配置为驱动第二支腿(3)相对于车架(1)运动,第一丝杠组件(4)和第二丝杠组件(5)相互配合,以使第一丝杠组件(4)中的驱动件驱动第二丝杠组件(5)中的驱动件运动,并使第一丝杠组件(4)驱动第一支腿(2)运动和第二丝杠组件(5)驱动第二支腿(3)运动同步进行。工程机械包括多级伸缩支腿系统。
