The embodiment of the invention provides a locking unit, a crawler belt and a walking device, relating to the field of engineering machinery. The locking unit comprises a connecting shaft, a check ring and two caterpillar track sections which are oppositely arranged. A first connecting hole is formed in each caterpillar track section, the two ends of the connecting shaft are in transition fit withthe first connecting holes of the two caterpillar track sections respectively, check rings are installed in the first connecting holes of the two caterpillar track sections respectively, and the twocheck rings abut against the two ends of the connecting shaft respectively so as to prevent the connecting shaft from moving in the axial direction of the connecting shaft. The crawler belt comprisesthe locking unit, and the walking device comprises the crawler belt. According to the locking unit, the caterpillar band and the walking device, the axial locking force of the connecting shaft is improved, it is guaranteed that the connecting shaft is not prone to moving out of the caterpillar track section during normal work, and meanwhile the connecting shaft is convenient to detach.

    本发明实施例提供了一种锁紧单元、履带及行走装置,涉及工程机械领域,该锁紧单元包括连接轴、挡圈以及相对设置的两个链轨节,每个链轨节上均设置有第一连接孔,连接轴的两端分别与两个链轨节的第一连接孔过渡配合,两个链轨节的第一连接孔内均安装有挡圈,两个挡圈分别抵接于连接轴的两端,以阻碍连接轴沿其轴向窜动。该履带包括前述的锁紧单元,该行走装置包括前述的履带。该锁紧单元、履带及行走装置既提高了连接轴的轴向锁紧力,保证了连接轴在正常工作时,不容易窜出链轨节,同时也具有方便拆卸连接轴的有益效果。
