The invention discloses a sealed casting impact seat. Comprising a hook door, a side wall plate and a top wall plate, wherein the front end of the hook door is of a rectangular sealing structure; a detachable coupler body wearing plate with an anti-falling function is installed on the coupler door bearing table below the coupler door, and a detachable coupler slave plate wearing plate is installed at the end of the side wall plate. The impact seat has the function of a front slave plate seat while supporting a coupler buffer device, and bears the longitudinal tensile load of a train; wear functional parts of the impact seat are all in detachable and replaceable structural forms and do not need to be cut and welded; the coupler door bearing table and the coupler body wearing plate are both provided with anti-falling structures, so that the situation that the coupler body wearing plate falls off accidentally to affect driving safety is avoided; the coupler slave wearing plate is stably connected with the striker longitudinal bearing table in a mode of countersunk head screws, elastic washers and locking nuts, so that the use function is ensured; on the premise that the strength and the rigidity of the impact seat are guaranteed, the self-weight is fully reduced, and the economy of parts is improved.
本发明公开了一种封口形铸造冲击座。包括前端矩形封口结构的钩门,侧壁板和顶壁板,冲击座后部及后侧底面为敞口结构;钩门下方钩门承载台上安装具有防脱功能且可拆卸的车钩体磨耗板,侧壁板端部安装有可拆卸的车钩从板磨耗板。本发明冲击座在支撑车钩缓冲装置的同时兼顾有前从板座的功能,承担列车纵向拉伸载荷;冲击座自带磨耗功能性零件均为可拆换结构形式,无需切割、焊接;钩门承载台和车钩体磨耗板均设有防脱结构,避免车钩体磨耗板意外脱落影响行车安全;采用沉头螺钉加弹性垫圈加锁紧螺母的方式将车钩从板磨耗板与冲击座纵向承载台稳固连接,保证使用功能;冲击座在保证自身强度、刚度的前提下,充分考虑减轻自重,提高零部件经济性。
