The invention relates to the technical field of engineering machinery, in particular to a supporting device and engineering machinery, the supporting device is used for being installed at a supporting leg of the engineering machinery, and the supporting device comprises a supporting leg disc; the telescopic oil cylinder comprises a telescopic rod which stretches out and draws back in the third direction; the support is arranged on the telescopic rod, a limiting rod is arranged on the support, and a limiting groove is formed in the limiting rod; the mounting seat is connected with the supporting leg disc through a connecting rod mechanism; the transmission assembly is configured to drive the supporting foot disc to move in the first direction through the support; the limiting assembly is configured to drive the limiting sliding block to move in the first direction when the telescopic rod stretches out. When the telescopic rod stretches out by a first length, the limiting sliding block moves into the limiting groove so as to limit relative movement between the support and the mounting base. The supporting foot disc is driven to stretch out and retract through the telescopic motion of the telescopic oil cylinder, the automation degree is high, and the purposes of labor saving and convenience in operation are achieved.
本发明涉及工程机械技术领域,特别是涉及一种支撑装置及工程机械,所述支撑装置用于安装在工程机械的支腿处,其包括:支脚盘;伸缩油缸,包括沿第三方向伸缩的伸缩杆;支座,设置在所述伸缩杆上,所述支座上设置有限位杆,所述限位杆上形成有限位槽;安装座,通过连杆机构与所述支脚盘连接;传动组件,被配置为通过所述支座带动所述支脚盘沿第一方向移动;限位组件被配置成在所述伸缩杆伸出时带动所述限位滑块沿第一方向移动;所述伸缩杆伸出第一长度时,所述限位滑块移入所述限位槽内以限制所述支座和所述安装座之间的相对运动。本发明通过伸缩油缸自身的伸缩运动来带动支脚盘伸出和缩回,自动化程度较高,以达到操作省力方便的目的。
