The invention relates to the technical field of engineering machinery maintenance, and discloses a track maintenance assembly and a track maintenance method.The track maintenance assembly comprises a caterpillar track assembly, a main pin shaft and an end plug, and the caterpillar track assembly comprises a pair of caterpillar track sections and a main pin bush which are integrally arranged. Shaft holes are formed in the two ends of each track link section respectively, the shaft holes are in clearance fit with the main pin shafts, the main pin sleeves are in clearance fit with the main pin shafts, the main pin shafts are in interference fit with the end plugs, and the shaft holes are in interference fit with the end plugs. A pair of caterpillar track sections and a main pin sleeve are preassembled into a caterpillar track assembly, the caterpillar track assembly is directly connected with an original caterpillar track in a front-back matched mode during replacement, a main pin shaft is in clearance fit with a caterpillar track section shaft hole and the main pin sleeve, installation is convenient, an end plug is in interference fit with the pin shaft and the caterpillar track section shaft hole, the pin channeling fault is prevented, stability and reliability after replacement are guaranteed, operation is easy, and cost is low. The device is simple in structure, convenient to use, free of special equipment, capable of avoiding damage to the remaining caterpillar track assemblies caused by fire baking, hammering and other modes, capable of improving replacement efficiency, capable of reducing maintenance cost and capable of guaranteeing operation safety.

    本发明涉及工程机械维修技术领域,公开了一种履带维修合件及履带维修方法,该履带维修合件包括链轨合件、主销轴和端塞,链轨合件包括一体设置的一对链轨节和主销套。链轨节两端分别设有轴孔,轴孔与主销轴之间、主销套与主销轴之间均为间隙配合,且主销轴与端塞之间、轴孔与端塞之间均为过盈配合。通过将一对链轨节和主销套预装为一个链轨合件,更换时直接同原链轨前后配合连接,且主销轴同链轨节轴孔和主销套间隙配合,方便安装,端塞同销轴及链轨节轴孔过盈配合,防止窜销故障,保证更换后的稳固性和可靠性,操作简单,使用方便,无需专用设备,且避免火烤、锤击等方式对剩余链轨组件造成损坏,提高更换效率,降低维修成本,保障操作安全性。
