Description of the Related Art Conventionally, a device called a sanding device has been attached to a bogie of a railway vehicle in order to prevent slippage between wheels and rails in a railway vehicle. As shown in FIG. 2 , this sanding device uses a tank 4 called a sand box to store coarse sand (as an anti-slip material) having an average particle size of about 2 to 5 mm at a portion where a wheel 41 and a rail 42 come into contact.
3 is connected to a pipe 44 provided with an air nozzle 45 in the lower part of the tank 43, and the sand in the tank 43 is blown into the sand 4 by blowing air from the air nozzle 45.
6 was moved to the tip 47 of the pipe 44 through the inside of the pipe, so that sand was dropped between the rail 42 and the wheel 41.

を引き起こす問題があった。However, when the above-mentioned conventional sanding device is used while the vehicle is running, the sand, which is an anti-slip material, is supplied onto the rail in a state close to natural fall, so that the vehicle travels. Due to the wind pressure caused by the sand scattered before reaching the rail, and even if it fell on the rail surface, it jumped, the rate of sand remaining between the rail and the wheel was low,
In order to obtain sufficient friction between the wheels and the rails, it was necessary to spray a large amount of sand. In addition, in a section where sand is constantly sprayed, there is a problem that sand accumulates in the track and causes adverse effects such as clogging of the trackbed.

It is required to increase the coefficient of friction between the rail and the wheels during acceleration and deceleration to prevent slippage during high-speed running as well as during starting. In response to such demands, the conventional sanding device has little effect of preventing slipping even when the amount of sand is increased during high-speed running, and almost no sand remains on the rails. There was a problem that the conventional sanding device could not be used for the purpose.

You. Therefore, the apparatus of the present invention provides a cross section at the tip of the injection nozzle.
Can be formed small and spray anti-slip material at high pressure
Ability to prevent slippage at the exact location between the rail and the track
Can supply stop material. Also, because high pressure injection is possible,
If dust or water adheres to the tip of the spray nozzle,
Even though they are blown off at high pressure,
There is no danger that the stop material may become clogged in the nozzle and prevent injection,
Stable injection of anti-slip material is possible.
