The invention provides a stabilizing device and engineering machinery, and the stabilizing device comprises a supporting frame which is provided with a sliding groove; the supporting leg mechanism comprises a first supporting leg and a second supporting leg, one end of the first supporting leg is hinged to the supporting frame, and the other end of the first supporting leg is hinged to the second supporting leg; the pull rod mechanism comprises a public hinge piece and a plurality of pull rods hinged in sequence, two of the pull rods are correspondingly hinged to the first supporting leg and the second supporting leg respectively to form a multi-connecting-rod self-locking structure, any two adjacent pull rods are hinged through the public hinge piece, and the public hinge piece stretches into the sliding groove and can slide between the opening position and the closing position in a reciprocating mode; and the second supporting leg is correspondingly driven to be opened or closed relative to the first supporting leg. A steel wire rope in the prior art is replaced by the pull rod mechanism, rigid connection is formed, the situation that normal use cannot be achieved due to abrasion of the steel wire rope can be avoided, the pull rod mechanism can accurately and synchronously adjust relative movement between the first supporting leg and the second supporting leg, and safety risks caused by unstable supporting are eliminated.

    本发明提供一种稳定装置和工程机械,稳定装置包括:支撑架,开设有滑槽;支腿机构,包括第一支腿和第二支腿,第一支腿的一端铰接于支撑架,第一支腿的另一端和第二支腿铰接;拉杆机构,包括公共铰接件和多个依次铰接的拉杆,其中两个拉杆分别对应铰接第一支腿、第二支腿,以形成多连杆自锁结构,任意相邻的两个拉杆通过公共铰接件铰接,公共铰接件伸入滑槽内并能在张开位置和闭合位置之间往复滑动,以对应带动第二支腿相对第一支腿张开或闭合。本发明通过拉杆机构取代现有技术中的钢丝绳,形成刚性连接,能避免因钢丝绳磨损不能正常使用的情况,且拉杆机构能精确同步调整第一支腿和第二支腿之间的相对运动,消除了因支撑不稳导致的安全风险。
