Preheating section lifting device for annealing furnace

The utility model relates to a preheating section lifting device for an annealing furnace. The preheating section lifting device for the annealing furnace is applied to a stainless steel production process. The preheating section lifting device comprises a furnace housing, a preheating section supporting roll, a fixed support, a drive mechanism and a connecting rod mechanism, wherein the fixed support is fixedly arranged on the furnace housing; the drive mechanism is mounted on the fixed support and is in transmission connection with the connecting rod mechanism; the preheating section supporting roll is mounted in the furnace housing. The preheating section lifting device is characterized by also comprising a transmission lifting device and a lifting beam. The preheating section lifting device has the benefits that the bending and the deformation of the supporting roll in the annealing furnace are effectively avoided, the tension control and the production acceleration in the annealing furnace are facilitated, the production efficiency is greatly improved, the service life of the preheating section supporting roll is prolonged, and the equipment maintenance time and the maintenance cost are greatly reduced.
