AI Technical Summary
Technical Problem
[0007]本实用新型的目的是针对现有技术中存在的不足，提供一种刮泥机链条的链销锁卡结构及刮泥机，解决现有技术中工作链节链销锁卡结构容易在工作链节单头端与链销抱死时出现损坏的问题
Benefits of technology
[0017]本实用新型提供一种刮泥机链条的链销锁卡结构及刮泥机，其有益效果在于：该刮泥机链条的链销锁卡结构通过链销的穿设来连接相邻两个链节，链销一端的第一限位部作为其限位头部，穿设时链销的另一端穿入链节，第一限位部留在链节的一边外侧，卡垫通过其内部的通槽与带有第二限位部的缩径部避让配合，能够套接在缩径部的外侧，并通过其一侧与链节的另一边外侧转动贴合，通过转动链销能够使第二限位部对准卡垫上的第一限位凹槽，并通过窜动链销能够使第二限位部嵌入第一限位凹槽内，形成与卡垫的卡接，利用链销窜动后在第一限位部与链节之间形成间隙容纳卡环的卡入，卡环卡接在链销的外侧，并对链销进行进一步限位，实现链销的锁卡，这样的锁卡结构使得链销能够相对于链节转动，替代传统的工作链节与链销卡接配合的锁卡结构，既保留了链销安装与拆卸方便快捷的特点，又解决了链销抱死引起的链销端头锁止结构损坏的问题，提高了链条的稳定性和使用寿命，通过卡垫与链销的配合确保链销在动态负载下保持稳定运行，避免因摩擦抱死导致的链销损坏，能够增强刮泥机的整体运行稳定性和可靠性，减少维修维护频率和成本。
