With the annual increase of the transportation (the transportation is nearly 3 hundred million tons in 2017), the damage of rail bars (such as rails, steel rails and the like) is gradually increased, particularly the damage of the welding seams of the rail bar joints is gradually increased, so that the annual welding seam flaw detection workload is also gradually increased. For example, the welding rail workload of the welding rail group for detecting the part of the plastic railway is about 400 welding rails each year. Nowadays, the labor cost is higher and higher, and how to improve the flaw detection efficiency is more and more important in railway maintenance work.

At present, when the welding seam is operated, the couplant is smeared, tools such as a couplant bottle, a couplant backpack and an oil brush need to be carried, and the couplant is relatively complicated and is easy to forget after operation of operators. In addition, an oil brush is needed when the couplant is coated, and because the width of the oil brush is different from that of the rail head of the steel rail, the couplant can be repeatedly coated until the couplant is uniformly coated on the steel rail, so that flaw detection operation can be carried out, the requirement on the technical quality of operating personnel is high, and the coating uniformity efficiency is low. Based on this, this application provides one kind and has spraying and brush the function, can scribble the couplant on the rail fast evenly and scribble the device.
