The invention belongs to the field of engineering machinery, and particularly relates to an area-variable supporting foot tray which comprises a support, a first pin shaft structure and a second pin shaft structure. The support is provided with a supporting plate and a supporting block, and the first pin shaft structure is arranged on the supporting plate and used for limiting the supporting platein different states; the second pin shaft structure is arranged on the support and used for limiting a hydraulic oil cylinder; the supporting plate is provided with a first pin shaft hole and a second pin shaft hole; the first pin shaft hole and the second pin shaft hole are used for installing the first pin shaft structure, the first pin shaft hole corresponds to the position of the first pin shaft structure in the second state of the supporting foot tray, and the second pin shaft hole corresponds to the position of the first pin shaft structure in the first state of the supporting foot tray. The supporting foot tray structure can change the supporting area of the supporting foot tray, and therefore the problem that the existing scheme cannot give consideration to the contradiction between bearing capacity improvement and limited space storage can be solved.
本发明为工程机械领域,具体涉及一种面积可变式支脚盘,包括支座、第一销轴结构、第二销轴结构;所述支座上设置有支撑板和支撑块,所述第一销轴结构设置于支撑板上,用于对支撑板在不同状态下进行限位;所述第二销轴结构安装在支座上,用于对液压油缸进行限位;所述支撑板上设置有第一销轴孔和第二销轴孔;所述第一销轴孔和第二销轴孔用于安装第一销轴结构,所述第一销轴孔对应于支脚盘第二状态时第一销轴结构的位置,所述第二销轴孔对应于支脚盘第一状态时第一销轴结构的位置。该支脚盘结构可实现支脚盘支撑面积的变化,从而解决现有方案无法兼顾承载能力提升与有限空间收纳之间的矛盾问题。
