The invention discloses a leveling oil cylinder landing leg assembly and engineering machinery, and the leveling oil cylinder landing leg assembly comprises a mechanical cylinder mechanism which comprises a mechanical barrel and a piston sliding block (3) arranged in the mechanical barrel; the oil cylinder mechanism comprises an oil cylinder, a connecting block, a ball head saddle and an adapter cover fixed to the piston sliding block, the connecting block is fixed to the extending end of a piston rod of the oil cylinder, a spherical groove is formed in the connecting block, and the spherical surface of the ball head saddle is arranged in the spherical groove in a matched mode and protrudes out of the spherical groove; the upper plane of the ball head saddle is in contact with the bottom plane of the piston sliding block; and at least main body parts of the connecting block and the ball head saddle are limited in the adapter cover, and an isolation interval is formed between the connecting block and the ball head saddle and the adapter cover. Through the unique mechanical cylinder and oil cylinder mechanism, the horizontal load is mainly borne by the mechanical cylinder mechanism, and the vertical load is mainly borne by the oil cylinder mechanism, so that the oil cylinder landing leg leveling device can be effectively suitable for oil cylinder landing leg leveling in occasions with large horizontal load.

    本发明公开了一种调平油缸支腿总成及工程机械,包括:机械缸机构,其包括机械筒和设于该机械筒内的活塞滑块(3);油缸机构,该油缸机构包括油缸、连接块、球头鞍座和固定到所述活塞滑块上的转接盖,所述连接块固定于所述油缸活塞杆的伸出端且形成有球形凹槽,所述球头鞍座球面配合到所述球形凹槽内且凸出于该球形凹槽之外,以使得该该球头鞍座的上平面与所述活塞滑块的底平面接触;以及所述连接块和所述球头鞍座的至少主体部分限位于所述转接盖内,且与该转接盖之间具有隔离间隔。本发明通过独特的机械缸和油缸机构,水平载荷主要由机械缸机构承担,竖直载荷主要由油缸机构承担,从而能够有效地适用于水平载荷较大场合的油缸支腿调平。
