The invention discloses a supporting leg unfolding and folding chassis and engineering machinery. The supporting leg unfolding and folding chassis comprises a chassis frame, a plurality of supportingleg frame sets, a tire frame, a plurality of telescopic driving devices and tires; each supporting leg frame set comprises an inner supporting leg frame and an outer supporting leg frame which are arranged in parallel and are both perpendicular to the plane where the chassis frame is located; and one ends of the telescopic driving devices are hinged to the chassis frame, and the other ends are hinged to the inner supporting leg frames. According to the supporting leg unfolding and folding chassis, the chassis frame, the tire frame, the inner supporting leg frames and the outer supporting leg frames form a four-connecting-rod mechanism, the inner supporting leg frames rotate around the chassis frame under pushing of the telescopic driving devices, and then the outer supporting leg frames and the tire frame are driven to swing synchronously; and in the swinging process, the angle between the tires on the tire frame and the moving direction of the chassis is not changed all the time, adjustment and control are not needed, only the action of the telescopic driving devices needs to be controlled, the whole control structure and process are greatly simplified, and the production cost isremarkably reduced.

    本发明公开一种支腿展收底盘及一种工程机械,该支腿展收底盘包括底盘架、多个支腿架组、轮胎架、多个伸缩驱动装置和轮胎;每个支腿架组包括内支腿架和外支腿架,内支腿架和外支腿架平行设置、且均垂直于底盘架所在的平面;伸缩驱动装置的一端铰接于底盘架上,其另一端铰接内支腿架。本发明提供的支腿展收底盘由底盘架、轮胎架、内支腿架和外支腿架构成了四连杆机构,在伸缩驱动装置的推动下,内支腿架围绕底盘架转动,进而带动外支腿架和轮胎架同步摆动,在摆动的过程中轮胎架上的轮胎与底盘移动方向的角度始终不变而无需进行调整控制,仅仅需要控制伸缩驱动装置的动作即可,整个控制结构和过程大大简化,显著降低生产成本。
