The invention discloses a supporting leg device and engineering machinery, the supporting leg device comprises a supporting leg mechanism and an unlocking mechanism, the supporting leg mechanism comprises a supporting leg assembly and a supporting foot assembly arranged on the supporting leg assembly, and the supporting leg assembly is provided with an extension locking part; the unlocking mechanism comprises a locking piece and an unlocking driving assembly, the unlocking driving assembly is arranged on the telescopic driving end of the supporting leg assembly and is in driving connection with the locking piece, and the unlocking driving assembly is used for driving the locking piece to lock the extension locking part under the condition that the telescopic driving end performs extension movement and driving the locking piece to lock the extension locking part under the condition that the telescopic driving end performs retraction movement. And the locking piece is driven to unlock and extend out of the locking part. The supporting leg assembly does not need to be manually locked and unlocked, the unlocking driving assembly is driven through telescopic movement of the telescopic driving end of the supporting leg assembly, the unlocking driving assembly can drive the locking piece to automatically lock the supporting leg assembly and automatically unlock the supporting leg assembly, operation steps are omitted, operation time is saved, and operation is convenient and fast.

    本发明公开一种支腿装置及工程机械,支腿装置包括支腿机构和解锁机构,支腿机构包括支腿组件以及设于支腿组件上的支脚组件,支腿组件上设有伸出锁止部;解锁机构包括锁止件和解锁驱动组件,解锁驱动组件设于支脚组件的伸缩驱动端上并与锁止件驱动连接,解锁驱动组件用于在伸缩驱动端进行伸出运动的情况下,带动锁止件锁止伸出锁止部,以及在伸缩驱动端进行缩回运动的情况下,带动锁止件解锁伸出锁止部。支腿组件无需人工手动锁止和解锁,通过支脚组件的伸缩驱动端的伸缩运动带动解锁驱动组件,即可使得解锁驱动组件驱动锁止件自动锁止支腿组件和自动解锁支腿组件,省略了操作步骤,节省了操作时间,操作方便快捷。
