The invention relates to the technical field of engineering machinery, and discloses a supporting leg disc and engineering machinery. The landing leg disc comprises a landing disc, the landing disc comprises a lower support, and the top of the lower support is provided with a concave part; the upper support is arranged in the sunken part, and the upper support is provided with a body part and a protruding part; the upper cover plate is fixed to the lower support, an accommodating space is defined by the upper cover plate and the lower support, the body part is located in the accommodating space, and an avoiding hole for avoiding the protruding part is formed in the upper cover plate; and the flexible friction sliding block is arranged between the lower support and the upper support, and the flexible friction sliding block and the upper support are suitable for sliding in the concave part relative to the lower support when bearing the horizontal component force of the external force. The upper support and the lower support are in flexible connection, when the vertical oil cylinder connected with the upper support is subjected to horizontal component force of external force, the flexible friction sliding block and the upper support do ball swinging motion in the concave part relative to the lower support, the horizontal force transmitted into a structural part is reduced, the service life of the structural part is prolonged, and the structural part is prevented from being damaged in vibration and unbalance loading.

    本发明涉及工程机械技术领域,公开了支腿盘及工程机械。支腿盘包括:落地盘,落地盘包括:下支座,顶部具有凹陷部;上支座,设置在凹陷部中,上支座具有本体部和凸出部;上盖板,固定在下支座上且与下支座之间围成收容空间,本体部位于收容空间中,上盖板上设有避让凸出部的避让孔;柔性摩擦滑块,设置在下支座和上支座之间,柔性摩擦滑块和上支座适于在受到外力的水平分力时相对于下支座在凹陷部中滑动。上支座和下支座采用柔性连接,当与上支座连接的垂直油缸受到外力的水平分力时,柔性摩擦滑块、上支座相对于下支座在凹陷部中做摆球运动,减少传递到结构件中的水平力,延长结构件的使用寿命,使得结构件在振动和偏载中免受破坏。
