Railway track connecting piece with self-fastening warning structure
The railway track connecting piece with the self-fastening warning structure is applied to the field of railway tracks, an outer ring I internally provided with an inner clamping plate is rotationally installed in a pressing block, a rack rod is arranged to be driven by wheels to move up and down, and the rack rod is matched with meshing transmission of the rack rod and a one-way transmission wheel; self-fastening of the connecting piece is achieved through a fluted disc and meshing transmission of teeth on the fluted disc and a first gear ring, nut loosening caused by vibration is avoided, the firmness and stability of railway track connection after the connecting piece is used are effectively guaranteed, meanwhile, a protective shell is clamped above a pressing block, an elastic air bag is installed in a hole formed in the protective shell, and therefore the connecting piece is prevented from being damaged, and the service life of the connecting piece is prolonged. According to the connecting piece, the elastic air bag can be extruded when the nut is loosened, the liquid reagent in the elastic air bag is extruded into the display cavity, a worker can judge whether the connecting piece is loosened or not by observing the condition of the liquid reagent in the display cavity, and the worker can be warned when the connecting piece is loosened.
本发明提供了应用于铁路轨道领域的一种具有自紧固警示结构的铁路轨道连接件，本申请通过将内部设置有内夹板的外环一转动安装在压块内部，设置齿条杆受车轮驶过驱动上下移动，配合其与单向传动轮的啮合传动，以及齿盘上齿牙与齿环一的啮合传动，实现该连接件的自紧固，避免由于震动导致螺帽松动，有效保障了该连接件使用后铁路轨道连接的牢固稳定性，同时，通过将防护壳卡合在压块的上方，并在防护壳内开设的孔洞中安装有弹性气囊，使得螺帽在松动时可以挤压弹性气囊，将弹性气囊内的液体试剂挤入显示腔内，工作人员可以通过观察显示腔内液体试剂状况，实现对该连接件松动与否的判定，有利于在该连接件松动时对工作人员进行警示。
