[0002] Sponge iron (DRI) is also called direct reduced iron, mainly used for electric furnace steelmaking instead of scrap steel. Sponge iron production is stacked in reaction tank 8 after layering loading iron scale and reducing agent raw materials, and is made in tunnel kiln by oxidation-reduction reaction. During firing, reaction tank 8 needs to be stacked and placed on kiln car 7 (rail car), and kiln car 7 runs along the track composed of two guide rails 5, so as to pull the reaction tank into the tunnel kiln for firing processing. The existing kiln car enters the tunnel kiln for firing operation, or unloads the tank after firing, when the kiln car reaches the parking point, if it stops suddenly, the stacked reaction tank will collapse due to inertia, which has great safety hazard. Therefore, a buffer device is needed at the parking point of the rail car to buffer the kiln car, so as to ensure the stable parking of the kiln car. SUMMARY
