Replacing one kind of carriage means

The method and apparatus of the present invention relates to a replacement carriage, belonging to the metallurgical industry sintering machine, a belt roaster to replace Field carriage. The apparatus comprises a carriage, the straight track, the bends, the straight outer rail, the outer bends, the main drive wheel, the carriage rails move, move the carriage rail, the outer sides of the bend of the main drive wheel into a lower movable external bends, fixed outer middle bend, the movable upper outer bend; lower movable upper rail and the lower end of the outer curved outer bend middle fixing hinge; the movable upper end and an outer bend track hinged at one end into the carriage. The present invention may be implemented or belt sintering machine to replace the firing carriage in a non-stop conditions, no additional vehicle replacement time, improve production efficiency; no sintering machine or belt machine downtime and firing performed to stop the wind or wind Save other operations, no change in the production conditions, relatively stable; since the stable production conditions, product yields and drum index is not reduced.
