Head collision buffering device for mining narrow gauge vehicle

The utility model provides a mining narrow-gauge vehicle collision buffer device which comprises a buffer plate, a first hole and a second hole are formed in the buffer plate, and the buffer plate penetrates through the first hole and the second hole through a pin and is arranged on a mining narrow-gauge vehicle through a cotter pin; the stress plate is connected to the buffer plate; the limiting plate is fixed to the mining narrow gauge vehicle and connected with the buffering plate in a clamped mode so as to solve the problems that an existing collision buffering device for the mining narrow gauge vehicle often derails when the mining narrow gauge vehicle collides with the collision buffering device, protection is not comprehensive enough, and the collision buffering device is not prone to falling off from a road when the mining narrow gauge vehicle collides with the collision buffering device. And when collision occurs, the buffering device is damaged due to the falling phenomenon of the mining narrow gaug
