[0020] Please see Figures 1-4This utility model discloses a furnace cover lifting and moving device for a well-type furnace used in the heat treatment of wind power flanges. It includes a furnace cover lifting device 1, with a left-right moving component installed inside the device. A movable lifting base 5 is mounted on the outer surface of the left-right moving component. The inner surface of the movable lifting base 5 is in movable contact with the outer surface of the furnace cover lifting device 1. A lifting power component is mounted on the outer surface of the furnace cover lifting device 1. Two driven shafts 11 are movably installed inside the movable lifting base 5. Two limiting recovery discs 12 are mounted on the outer surface of each of the two driven shafts 11. A lifting groove 13 is opened inside the movable lifting base 5. Chains 21 are fixedly mounted on the outer surfaces of the four limiting recovery discs 12. One end of each chain 21 is equipped with... With hooks 20, a fixing component is installed on the top surface of the movable lifting base 5. Four chains 21 are synchronously wound and lifted through the limiting recovery disc 12, ensuring that the lifting force of the hooks 20 on the well furnace cover 15 is evenly distributed, avoiding tilting or shaking of the well furnace cover 15 during the lifting process, thereby improving the stability of the lifting. The simultaneous force of the four chains 21 makes the weight of the well furnace cover 15 evenly distributed, reducing the load pressure on a single chain 21, extending the service life of the chain 21, realizing the automatic lifting of the well furnace cover 15, simplifying the operation process, reducing the complexity of manual operation, and the limiting recovery disc 12 effectively prevents the chains 21 from falling off during the lifting process, ensuring the safety of the lifting process.

[0021] The left and right moving assembly includes a first motor 2 and a ball screw 3. The first motor 2 is mounted on the top surface of the furnace cover lifting device 1, and the ball screw 3 is mounted on the outer surface of the output end of the first motor 2. A screw slider 4 is movably mounted on the outer surface of the ball screw 3. The top surface of the screw slider 4 is fixedly connected to the bottom surface of the movable lifting base 5. A well-type furnace cover 15 is mounted on the inner side of the furnace cover lifting device 1. Four retaining ring plates 19 are evenly mounted on the outer surface of the well-type furnace cover 15. The outer surface of the hook 20 is in movable contact with the inner surface of the retaining ring plate 19. The lifting power assembly includes a second motor 6 and a rotating shaft 7. The second motor 6 is mounted on the inner surface of the movable lifting base 5, and the rotating shaft 7 is mounted on the outer surface of the output end of the second motor 6. A drive gear 8 is mounted on the outer surface of the rotating shaft 7. Driven gears 9 are mounted on the outer surfaces of the two driven shafts 11. A chain 10 is movably mounted on the outer surface of the drive gear 8 and the outer surfaces of the two driven gears 9. The fixing assembly includes a hydraulic press 14 and a connecting plate. 16. The hydraulic press 14 is installed on the top surface of the movable lifting base 5. The connecting plate 16 is installed on the outer surface of the output end of the hydraulic press 14.

The outer surface of the rubber retaining ring blocks 18 is in contact with the outer surface of the chain 21 and the inner surface of the limiting recovery disc 12. The hydraulic press 14 drives the connecting plate 16 and the four pressure blocks 17 to move synchronously. As the chain moves, the four pressure blocks 17 synchronously drive the rubber retaining ring blocks 18 to squeeze and fix the chain 21, thereby stabilizing the chain 21 within the limiting recovery disc 12, which in turn stabilizes the furnace cover 15 of the pit furnace. This ensures the stability of the chain 21 within the limiting recovery disc 12, thus guaranteeing that the furnace cover 15 of the pit furnace remains at the same height. This makes the squeezing of the chain 21 by the rubber retaining ring blocks 18 more uniform, further enhancing the stability of the chain 21. The powerful thrust of the hydraulic press 14 also ensures the overall stability.

[0022] The working principle and usage process of this utility model are as follows: When it is necessary to lift and move the furnace cover 15 of the well-type furnace that has just undergone heat treatment of the wind power flange, the controller controls the first motor 2 to work. The first motor 2 drives the ball screw 3 to rotate. The outer surface of the ball screw 3 cooperates with the inner balls of the screw slider 4, so that the screw slider 4 drives the movable lifting base 5 to move on the outer surface of the furnace cover lifting device 1, so that the movable lifting base 5 is moved above the furnace cover 15. The four hooks 20 are hung on the retaining ring plate 19 on the outer side of the furnace cover 15. The controller controls the second motor 6 to work. The second motor 6 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the driving gear 8 to rotate. The driving gear 8 drives the two driven gears 9 to rotate through the chain 10. The two driven gears 9 drive the driven shaft 11 to rotate. Two driven shafts 11 drive the limiting recovery discs 12 to rotate, and the four limiting recovery discs 12 wind and lift the chains 21, thereby enabling the four chains 21 to synchronously drive the hooks 20 to lift the furnace cover 15. The synchronous winding and lifting of the four chains 21 by the limiting recovery discs 12 ensures that the lifting force of the hooks 20 on the furnace cover 15 is evenly distributed, avoiding tilting or swaying of the furnace cover 15 during the lifting process, thus improving the stability of the lifting. The simultaneous force on the four chains 21 makes the weight of the furnace cover 15 evenly distributed, reducing the load pressure on a single chain 21, extending the service life of the chain 21, realizing the automatic lifting of the furnace cover 15, simplifying the operation process, reducing the complexity of manual operation, and the limiting recovery discs 12 effectively prevent the chains 21 from falling off during the lifting process, ensuring the safety of the lifting process.

[0023] When it is necessary to lift and raise the furnace cover 15 of the pit furnace to observe its bottom end, the hydraulic press 14 is controlled by the controller to work. The hydraulic press 14 drives the connecting plate 16 and the four pressure blocks 17 to move synchronously. The four pressure blocks 17 synchronously drive the rubber retaining ring block 18 to squeeze and fix the chain 21, thereby stabilizing the chain 21 within the limiting recovery plate 12. This also stabilizes the furnace cover 15 of the pit furnace, ensuring the stability of the chain 21 within the limiting recovery plate 12. This ensures that the furnace cover 15 of the pit furnace remains at the same height, making the squeezing of the chain 21 by the rubber retaining ring block 18 more uniform, further enhancing the stability of the chain 21. The powerful thrust of the hydraulic press 14 also ensures the overall stability.
