The invention discloses an independent steering type chassis of engineering machinery, the engineering machinery and a crawler-type tower crane, the independent steering type chassis of the engineering machinery comprises a support leg unit loading assembly, leveling telescopic support leg units (2) and a walking mechanism, each lower loading support part at the bottom of the support leg unit loading assembly is correspondingly supported and connected to the upper part of the corresponding leveling telescopic support leg unit through a spherical hinge (4); steering rotation driving mechanisms are installed between the bottom of the landing leg unit loading assembly and the upper portions of the leveling telescopic landing leg units respectively, the lower portions of the leveling telescopic landing leg units are connected to the corresponding walking mechanisms respectively, and the walking mechanisms form independent walking mechanisms. And each walking mechanism is provided with an auxiliary supporting leg mechanism (6). Aiming at the application occasion of large or ultra-large engineering machinery, such as a movable tower crane, the leveling telescopic supporting leg units and the walking mechanisms on the upper part and the lower part are originally connected through the spherical hinges, so that the unique chassis with each walking mechanism capable of steering independently is formed.
本发明公开了一种工程机械独立转向式底盘、工程机械和履带式塔机,其包括支腿单元上装总成、调平伸缩支腿单元(2)以及行走机构,其中支腿单元上装总成底部的各个下装支承部通过球铰(4)对应支承连接到相应的调平伸缩支腿单元的上部,且所述支腿单元上装总成底部与各个调平伸缩支腿单元的上部之间分别安装有转向旋转驱动机构,各个调平伸缩支腿单元的下部分别连接到相应地行走机构上,各个行走机构形成为独立行走机构,且各个行走机构上安装有辅助支承支腿机构(6)。本发明针对大型或超大型工程机械,例如移动式塔机的应用场合,独创性地通过球铰连接上装与下部的调平伸缩支腿单元和行走机构,从而形成独特的各个行走机构独立转向的底盘。
