This utility model is the deficiency solving above-mentioned technical problem, be the technical scheme is that
nullA kind of lifting device of large-scale bogie furnace furnace door，Including fire door and fire door support，The both sides of fire door are separately installed with motor I、Counterweight I、Motor II and counterweight II，Motor I and motor II is installed on fire door support and lays respectively at fire door both sides，It is respectively and fixedly provided with sprocket wheel on the outfan of motor I and motor II，Chain I and chain II it is arranged with respectively on sprocket wheel，One end of chain I is connected with counterweight I，The other end is connected near the side of motor I with fire door top，One end of chain II is connected with counterweight II，The other end is connected near the side of motor II with fire door top，Described fire door cradle top is additionally provided with a pair pitch wheel and a pair synchronous sprocket wheel，Synchronous sprocket wheel and gear are arranged with rotary shaft，Synchronous sprocket wheel synchronous axial system is driven by gear engagement，Chain I is set in the synchronous sprocket wheel of motor I side，Chain II is set in the synchronous sprocket wheel of motor II side，Chain I and the Synchronous lifting of chain II is realized by synchronous sprocket wheel synchronous axial system under gearing.
Being additionally provided with jockey sprocket I and jockey sprocket II on described fire door support, chain I walks around the sprocket wheel on motor I, the synchronous sprocket wheel of close motor I side and jockey sprocket I successively；Chain II walks around the sprocket wheel on motor II, the synchronous sprocket wheel of close motor II side and jockey sprocket II successively.
Gear mesh crossbeam owing to increasing produces additional downward pressure, and in order to prevent pressure from occurring, rear cross beam produces bending stress, carries out "eight" shape reinforcing at two heel posts and crossbeam top, and being top increases reinforcement again,
By transforming on the large-scale heat treatment the widest in steel foundry 9.5 × 18m, two industries of 8.5 × 14m.9.5 × 18m, 8.5 × 14m stove are through the production run of 15 months, this fire door stable working, then do not occur causing stuck phenomenon because of inclination, reach the expection that fault rate is greatly reduced and ensures safety in production.
The beneficial effects of the utility model are: this utility model is set up Double-gear+double chain wheel on the upside of fire door and engages each other the chain syn-chro-step device that the mid-ambles of composition is taken turns between two hoisting mechanisms, engaged by a pair identical gear of parameter, reach rotating speed identical, oppositely oriented, mutually system is taken along, then by the Traction Drive of two pairs of gear shaft upper sprocket wheels, make to lift synchronization lifting along both sides lifting chain on fire door, this fire door stable working, do not occur causing because of inclination stuck phenomenon again, reach fault rate and be greatly reduced and ensure safety in production.
