[0027] Firstly, the furnace door 3 is symmetrically distributed and fixedly installed on one side of the furnace body 1 through two limiting plates 2. This design can ensure that the furnace door 3 can smoothly slide between the two limiting plates 2, so as to realize the lifting action of the furnace door 3. The mounting plate 4 is fixedly installed on the top of the furnace door 3, and two steel wires 5 are detachably installed on the top of the mounting plate 4. This design facilitates the installation and maintenance of the steel wires 5. The support frame 6 is fixedly installed on the top of the furnace body 1, and a winding shaft 7 is rotatably installed on one side of the support frame 6. One end of the steel wire 5 is fixedly connected with the outer surface of the winding shaft 7. The support frame 6 is also provided with a driving assembly 8 for driving the winding shaft 7 to rotate.

[0028] In addition, the positioning plate 9 is also fixedly installed on one side of the limiting plate 2, and a long gear 10 is rotatably installed between the two positioning plates 9.

Finally, the limiting assembly 12 is installed on the furnace body 1 for limiting and fixing the long gear 10, preventing the abnormal falling of the furnace door 3, and ensuring the safety of the whole lifting mechanism.

[0029] When it is necessary to open or close the furnace door 3, the driving assembly 8 is started to drive the steel wire 5 to be wound through the rotation of the winding shaft 7, so as to make the furnace door 3 rise or fall. At the same time, the engagement transmission of the long gear 10 and the teeth 11 ensures the smooth lifting of the furnace door 3, avoiding the out-of-sync problem that may occur in the traditional hydraulic cylinder driving mode. The limiting assembly 12 limits the long gear 10 during the whole process, preventing the danger of the furnace door 3 falling, and ensuring the stability and safety of the furnace door 3 lifting mechanism.

The two ends of the long gear 10 are fixedly provided with blocks 123, and the four faces of the blocks 123 are provided with clamping grooves. The design of the clamping grooves is used to match the clamping plate 122, so as to limit the long gear 10. When the furnace door 3 needs to be lifted or lowered, the driving assembly 8 is started and drives the furnace door 3 to rise or fall through the steel wire rope 5 and the winding shaft 7. At the same time, the long gear 10 is engaged with the gear teeth 11 to realize the stable lifting of the furnace door 3. When the furnace door 3 completes the lifting action and reaches the predetermined position, the air cylinder 121 controls the clamping plate 122 to extend and be clamped with the clamping groove on the block 123, so as to fix the position of the long gear 10 and prevent the furnace door 3 from falling accidentally. The four faces of the block 123 are provided, and four positions can be set according to the needs. When it is needed to move again, the air cylinder 121 can control the clamping plate 122 to retract and move out of the clamping groove, so as to allow the long gear 10 to rotate freely in the next operation.
