Telescopic supporting device and working machine
The invention provides a telescopic supporting device and an operation machine. The telescopic supporting device comprises a telescopic arm; the supporting leg is fixedly connected with the telescopic arm; a turret base in which a leg box for accommodating the telescopic arm is formed; the telescopic arm can telescopically move relative to the supporting leg box; a supporting plate in contact fit with the bottom of the telescopic arm is arranged at the bottom of the inner side of the supporting leg box. Thus, no matter how the telescopic arm stretches out and draws back, the force bearing point of the turret base is kept on the supporting plate all the time, and therefore the telescopic arm is prevented from making contact with a weak area at the bottom of the supporting leg box, stress deformation of the bottom of the supporting leg box is reduced, and the structural safety of the supporting leg box is improved. Meanwhile, the lap joint position of the telescopic arm and the landing leg box is always on the supporting plate, namely the lengths of the arms of force are kept consistent, so that the weight of the landing leg box is reduced, and the cost is reduced.
本申请提出了一种伸缩支撑装置及作业机械。该伸缩支撑装置包括伸缩臂；支撑腿，和所述伸缩臂连接固定；转塔座，形成有收纳所述伸缩臂的支腿箱；所述伸缩臂可相对于所述支腿箱作伸缩移动；所述支腿箱的内侧底部设有和所述伸缩臂底部接触配合的托板。这样一来，无论伸缩臂如何伸缩，转塔座的承力点一直保持在托板上，从而避免伸缩臂和支腿箱的底部薄弱区域接触，以减小支腿箱底部的受力变形，提高支腿箱的结构安全性；同时，由于伸缩臂和支腿箱的搭接位置始终在托板上，即力臂长度保持一致，从而有利于减轻支腿箱的重量，降低成本。
