The invention relates to a locomotive vehicle cowcatcher installation structure which comprises a vehicle body, a cowcatcher, an inclined supporting beam, supporting legs, a front vehicle body installation base, a rear vehicle body installation base, supporting leg installation bases and an inclined supporting beam installation base. The front vehicle body installation seat is horizontally fixed at the bottom of the front side of the vehicle body, the supporting leg installation seat is horizontally fixed at the top end of the supporting leg, and the front vehicle body installation seat is fixedly connected with the supporting leg installation seat through a vertical threaded fastener; the inclined supporting beam installation base is perpendicularly fixed to the top end of an inclined supporting beam, the upper end face of the rear vehicle body installation base is fixedly connected with the bottom of the rear side of a vehicle body in parallel, and the lower end face of the rear vehicle body installation base is fixedly connected with the inclined supporting beam installation base in parallel. The lower end face of the rear vehicle body installation base is fixedly connected with the inclined supporting beam through a vertical threaded fastener. The situation that the cowcatcher bears shear force when a threaded fastener is installed is avoided, and the safety coefficient is increased; meanwhile, the axial mechanical performance of the threaded fastener is fully utilized, light weight of the design is facilitated, and the cost and the working intensity of installation personnel are reduced.

    本发明涉及一种机车车辆排障器安装结构,包括车体、排障器、斜支撑梁、支撑腿、前车体安装座、后车体安装座、支撑腿安装座和斜支撑梁安装座;所述前车体安装座水平固定在车体前侧底部,所述支撑腿安装座水平固定在支撑腿顶端,所述前车体安装座与支撑腿安装座通过垂直的螺纹紧固件固定连接;所述斜支撑梁安装座垂直固定在斜支撑梁顶端,所述后车体安装座的上端面与车体后侧底部平行固定连接,所述后车体安装座的下端面与斜支撑梁安装座平行固定连接,所述后车体安装座的下端面与斜支撑梁通过垂直的螺纹紧固件固定连接。本发明避免了排障器安装螺纹紧固件承受剪切力的情况,提高了安全系数;同时充分利用螺纹紧固件的轴向机械性能,利于设计的轻量化,降低成本和安装人员的工作强度。
