17型车钩防跳性能不良的调研分析

Investigation and Analysis of the Bad Anti-jump Performance of Type 17 Coupler

针对货车检修过程中17型车钩组装作业时部分车钩防跳性能不良的问题,通过现场调研、原理分析和试验验证,提出了加强17型车钩源头制造质量控制,增加钩体下锁腔的锁铁导向台宽度,提高导向台焊修质量,增加下锁销长度检修标准的解决方案。

In view of the problem that the anti-jump performance of some couplers in the assembly operation of type 17 couplers in the course of truck maintenance is poor,through principle analysis,field investigation and test verification,a solution is put forward to strengthen the manufacturing quality of type 17 couple,increase the width of lock iron guide table,improve the welding repair standard of the guide table and increase the repair standard of lower lock pin length.
