The invention relates to the technical field of internal combustion locomotives, in particular to an internal combustion locomotive cab with multi-stage collision protection, which comprises a cab upper top cover, a cab lower enclosure, a locomotive body underframe and a cab rear end wall, wherein a buffer energy absorption device I is arranged at the front end of the locomotive body underframe, and a buffer energy absorption device II is arranged at the front end of the cab front end wall. According to the internal combustion locomotive cab with the multi-stage collision protection function,multi-stage safety protection measures are built for the internal combustion locomotive cab through the method that the buffer energy absorption devices are arranged at the end of the locomotive bodyunderframe and the lower portion of the front end of the cab, and the lower structure of the cab is designed to be of an integral frame-shaped structure; in order to give full play to the protection effect of the buffer energy absorption devices on the cab structure in the collision process and fully utilize the locomotive space, the buffer energy absorption devices are arranged at the end of thevehicle body underframe and the lower portion of the front end of the cab in a relatively independent rectangular array mode.

    本发明涉及内燃机车技术领域,尤其是一种具有多级碰撞保护的内燃机车司机室,包括司机室上顶盖、司机室下部围挡、车体底架和司机室后端墙,所述车体底架前端设有缓冲吸能装置一,所述司机室前端墙前端设有缓冲吸能装置二。本发明的一种具有多级碰撞保护的内燃机车司机室,通过在车体底架端部、司机室前端下部设置缓冲吸能装置和将司机室下部结构设计成整体框形结构的方法,为内燃机车司机室构建多级安全保护措施;为了充分发挥缓冲吸能装置在碰撞过程对司机室结构保护效果和充分利用机车空间,缓冲吸能装置在车体底架端部和司机室前端下部以相对独立的矩形阵列方式排布。
