The invention relates to the field of crawler walking mechanisms, and provides a crawler device, a crawler chassis and an operation machine. The chain track is formed by sequentially connecting a plurality of chain links end to end, and the left chain plate and the right chain plate of each chain link are connected through a telescopic pin shaft. The multiple track shoes are arranged on the left chain plate and the right chain plate in a one-to-one correspondence mode. According to the crawler belt device, the left chain plate and the right chain plate are connected through the telescopic pin shaft, and the crawler belt plates connected to the left chain plate and the right chain plate are of independent structures, so that when the thrust wheel moves leftwards or rightwards in the axial direction of the thrust wheel under the action of eccentric loads, the thrust wheel can drive the left chain plate or the right chain plate to move in the unbalance loading direction; and meanwhile, the corresponding track shoe is driven to move in the unbalance loading direction, so that the axial extrusion force between the thrust wheel and the caterpillar track can be reduced, and the problem of faults such as abrasion, oil leakage and the like of the thrust wheel caused by mutual extrusion of the thrust wheel and the caterpillar track in the related technology is solved.
本发明涉及履带行走机构领域,提供一种履带装置、履带底盘和作业机械,包括支重轮、链轨和履带板。链轨由多个链节首尾顺次连接而成,每个链节的左链板与右链板之间通过伸缩销轴连接。履带板包括多个,且多个履带板一一对应的设置在左链板和右链板上。本发明提供的履带装置,由于左链板和右链板之间由伸缩销轴连接,且连接在左链板和右链板上的履带板为独立结构,当支重轮在偏心载荷的作用下沿自身轴向向左或向右运动时,支重轮会带动左链板或右链板向偏载方向运动,同时带动对应的履带板向偏载方向运动,如此可以减小支重轮与链轨之间的轴向挤压力,解决相关技术中由于支重轮与链轨相互挤压导致支重轮出现磨损漏油等故障的问题。
