The invention relates to the technical field of locomotive traction devices, in particular to a bolt connection structure of a locomotive traction device. A locomotive traction device bolt connection structure comprises a traction seat plate, a traction pin and a bolt and nut assembly. The peripheral side of the traction seat plate is welded to a locomotive body chassis, and a plurality of first mounting holes are formed in the traction seat plate. The traction pin comprises a flange plate, and a plurality of second mounting holes corresponding to the first mounting holes are formed in the flange plate. The bolt of each bolt and nut assembly penetrates through the corresponding first mounting hole and the corresponding second mounting hole and is connected with the corresponding nut, and the flange plate is fixedly connected with the traction base plate. The traction seat plate or the flange plate is provided with an anti-loosening structure used for limiting rotation of the nut. The anti-loosening structure used for limiting rotation of the nut is arranged on the traction base plate or the flange plate, so that the anti-loosening effect can be improved, and the operation safety of a locomotive is guaranteed.

    本发明涉及机车牵引装置技术领域,具体涉及一种机车牵引装置螺栓连接结构。一种机车牵引装置螺栓连接结构包括:牵引座板、牵引销和螺栓螺母组件。牵引座板的周侧焊接于机车车体底架,牵引座板上设置有多个第一安装孔。牵引销包括法兰盘,法兰盘上设置有与多个第一安装孔对应设置的多个第二安装孔。螺栓螺母组件有多个,每个螺栓螺母组件的螺栓穿过第一安装孔和第二安装孔并与螺母连接,将法兰盘与牵引座板固定连接。其中,牵引座板或法兰盘上设置有用于限制螺母转动的防松结构。本申请通过在牵引座板或法兰盘上设置用于限制螺母转动的防松结构,能够提高防松效果,保证机车的运行安全。
