The invention belongs to the technical field of engineering machinery and provides a supporting leg mechanism and the engineering machinery, the supporting leg mechanism comprises a fixed supporting leg, a movable supporting leg and an oil cylinder assembly, the rear end of the fixed supporting leg is provided with a mounting face arranged backwards, the movable supporting leg is arranged in the fixed supporting leg in a penetrating mode, and the oil cylinder assembly comprises an oil cylinder body and an oil cylinder mounting base; the oil cylinder mounting seat is attached to and detachably mounted on the mounting surface through a threaded connecting piece, one of a piston rod and a cylinder body of the oil cylinder body is connected with the oil cylinder mounting seat, the other one of the piston rod and the cylinder body of the oil cylinder body is connected with the movable supporting leg, and the connecting direction of the threaded connecting piece is the same as the penetrating direction of the movable supporting leg. According to the supporting leg mechanism, the horizontal oil cylinder can be directly detached and drawn out from the rear end of the fixed supporting leg, and the threaded connecting piece can be prevented from being affected by shear stress.
本申请属于工程机械技术领域并提供一种支腿机构及工程机械,支腿机构包括固定支腿、活动支腿和油缸组件,固定支腿的后端设有朝后设置的安装面,活动支腿穿设在固定支腿内,油缸组件包括油缸本体和油缸安装座,油缸安装座贴设并通过螺纹连接件可拆卸安装在安装面上,油缸本体的活塞杆与缸体的其中一者与油缸安装座连接,另一者与活动支腿连接,其中,螺纹连接件的连接方向与活动支腿的穿设方向相同。本申请中的支腿机构能够直接将水平油缸从固定支腿的后端拆下抽出,且能够避免螺纹连接件受剪切应力影响。
