The push-pull type fully-foldable chassis structure of the crane comprises a sleeve disc frame, a supporting frame is fixedly installed at the bottom of the sleeve disc frame, first outward-turning sleeve frames are movably installed on the two sides of the surface of the sleeve disc frame, and first embedded supporting plates are slidably installed in the first outward-turning sleeve frames; a plurality of positioning sleeve openings are sequentially formed in the side faces of the first embedded supporting plates and the side faces of the first outwards-turned sleeve frames, and universal wheels are installed at the bottoms of the outer sides of the first embedded supporting plates. According to the push-pull type fully-foldable underframe structure of the crane, through the action of the first outwards-turned sleeve frames movably installed on the two sides of the sleeve disc frame and the movable installation action of the second outwards-turned sleeve frames on the upper side of the square frame, the push-pull type fully-foldable underframe structure can be folded downwards to be of a flat plate structure, the occupied area of the crane is greatly reduced, and carrying and storage are convenient; the problems that an existing foldable crane is not high in folding degree and difficult to fold into a flat-plate-like structure are effectively solved.

    本发明提供的一种起重机推拉式且可全折叠的底架结构,包括套盘框,支撑架固定安装于套盘框的底部,套盘框的表面两侧均活动安装有第一外翻套框,第一外翻套框的内部滑动安装有第一内嵌支板,第一内嵌支板与第一外翻套框的侧面均依次安装有多个定位套口,第一内嵌支板的外侧底部均安装有万向轮。本发明提供的一种起重机推拉式且可全折叠的底架结构,通过套盘框两侧活动安装的第一外翻套框的作用,配合方形框上侧第二外翻套框的活动安装作用,可以向下折叠为平板结构,极大的减少了起重机的占用面积,方便携带收纳,有效的解决了现有其提供的一种可折叠起重机可折叠程度不高,难以折叠为类平板结构的问题。
