The limiting mechanism comprises a limiting mechanism of a width-adjustable frame. The limiting mechanism comprises a main frame, a left crawler belt frame and a right crawler belt frame, wherein inner sides of the two crawler belt frames are each provided with two sliding rails inserted into the main frame, and a hydraulic cylinder mechanism connected with the two crawler belt frames is arrangedin the main frame in a sliding mode. The limiting mechanism of the width-adjustable frame belongs to the technical field of excavators, is ingenious in structure and convenient in hydraulic adjustment, can realize width adjustment of the frame only by one hydraulic cylinder mechanism and simple connection, and is simple in structure and lower in cost, the left crawler frame and the right crawler frame slide through matching of sliding rails and sliding grooves, so telescopic stability and flexibility of the frame are higher.
本发明公开了一种调宽车架的限位机构,包括主车架和左、右两个履带架,两个所述履带架的内侧均设有两个插入所述主车架设置的滑轨,所述主车架内滑动设有与两个所述履带架连接的液压缸机构。本发明的调宽车架的限位机构,属于挖掘机技术领域,结构巧妙,液调节方便,只用一个液压缸机构及简单的连接可实现车架的调宽,结构简单,成本较低;左、右履带架是通过滑轨和滑槽的配合实现滑动,使车架的伸缩稳定性及灵活性更高。
