The invention provides a supporting leg device, a chassis and a high-altitude operation machine.The supporting leg device comprises a supporting leg mechanism, a sliding mechanism and a shear type telescopic boom frame, the supporting leg mechanism comprises a fixed supporting leg and a telescopic supporting leg arranged in a telescopic mode, and a first sliding groove is formed in the fixed supporting leg; the sliding mechanism comprises a driving sliding block movably clamped in the first sliding groove and a transmission connecting assembly in transmission connection between the telescopic supporting leg and the driving sliding block, and the transmission connecting assembly is used for converting telescopic force of the telescopic supporting leg into driving force for driving the sliding block to slide in the first sliding groove. The shear type telescopic arm frame comprises a fixed arm section and a driving arm section which are arranged in a crossed mode, the fixed arm section is fixedly connected with the fixed supporting leg, and the driving arm section is fixedly connected with the driving sliding block. According to the supporting leg device, the horizontal telescopic action and the vertical telescopic action of the supporting leg device can be achieved only through one set of driving oil cylinders, meanwhile, the horizontal telescopic action and the vertical telescopic action can be conducted synchronously, and the expansion and contraction efficiency of the supporting leg device is greatly improved.

    本发明提供一种支腿装置、底盘及高空作业机械,支腿装置包括支腿机构、滑动机构和剪式伸缩臂架,支腿机构包括固定支腿和伸缩设置的伸缩支腿,固定支腿上设有第一滑槽,滑动机构包括活动卡接在第一滑槽内的驱动滑块以及传动连接在伸缩支腿和驱动滑块之间的传动连接组件,传动连接组件用于将伸缩支腿的伸缩力转换为驱动滑块在第一滑槽内滑动的驱动力,剪式伸缩臂架包括交叉设置的固定臂节和驱动臂节,固定臂节与固定支腿固定连接,驱动臂节与驱动滑块固定连接。本发明所提供的支腿装置仅需要一组驱动油缸便可实现支腿装置的水平伸缩动作和竖向伸缩动作,同时水平伸缩动作和竖向伸缩动作能够同步进行,大大提升支腿装置的展开和收缩效率。
