Track lubrication spraying device

The invention discloses a track lubrication spraying device. The track lubrication spraying device is designed according to the shape of a train track and installed on the side face of a rail, an oilpumping device with a plurality of oil outlets and a plurality of pump cores is arranged, every two oil outlets are connected in series through an injection assembly, and each oil passage in a main plate of a coating plate is connected with at least two oil outlets; the stability of oil supply is improved through structure arrangement of the injection assemblies, when the oil outlet of the oil pumping device is blocked, other oil outlets can supply oil to the corresponding oil passage connected with the blocked oil outlet, the oil pump capacity is stable and the spraying quantity is even, andthe lubrication effect is significantly improved; and soft oil grooves are formed, lubricants transported by the oil passages are temporarily stored in the soft oil grooves, when a train squeezes thesoft oil grooves through wh
