Chain type stepping mechanism for transferring tunnel type formwork roasting furnace kiln car in casting area

The utility model discloses a chain type stepping mechanism for transferring a tunnel type formwork roasting furnace kiln car in a casting area, which solves the problems that in the prior art, molten steel overflows to damage equipment, the maintenance is frequent, the maintenance cost is high and the like, and is characterized in that a protective plate is arranged above a chain type stepping machine; the chain type stepping machine and the kiln car are intermittently driven through a driving rod and a kiln car propelling device, a movable force exerting plate on the kiln car ensures that the kiln car is driven by the chain type stepping machine to operate when moving forwards, and when the kiln car moves backwards, the movable force exerting plate passes through the driving rod and is not limited by the chain type stepping machine. A good transfer mode is provided for the tunnel type formwork roasting kiln, operation smoothness is improved, productivity is greatly improved, compared with an existing chain
