[0029] like Figures 1 to 7As shown, this utility model discloses an automatic ladle capping device, including a ladle assembly 1, a capping assembly 2, a cover plate 3, a control module (not shown in the figure), and an identification module (not shown in the figure). The ladle assembly 1 includes a conveyor belt 11, with a ladle 12 placed on top of the conveyor belt 11. The capping assembly 2 includes a trolley frame 22 and a track 21 positioned above the ladle 12. The track 21 has a hardened surface to ensure high wear resistance. The trolley frame 22 is welded from high-strength steel plates and has internal reinforcing ribs to ensure structural strength. Third fasteners 23 are threaded to both ends of the front and rear sides of the trolley frame 22. The trolley frame 22 is fixedly connected to the wheel assembly 24 via a third fastener 23. The wheel assembly 24 is made of cast steel. A second hydraulic cylinder 213 is fixedly connected to one side of the trolley frame 22, and the other end of the second hydraulic cylinder 213 is fixedly connected to the factory building. The track 21 is fixedly connected to the top of the factory building by high-strength bolts. This not only makes full use of space and avoids interference from ground equipment, but also shortens the running path of the cover component 2, improving work efficiency. The wheel assembly 24 is slidably connected to the top of the track 21 via wheels. The second hydraulic cylinder 213 directly drives the trolley frame 22, providing stable thrust. The surface of the wheels is inlaid with bronze. The bushing has anti-slip textured surfaces at its contact with the track 21 to improve sliding stability. A single hook shaft 25 is fixedly connected to one side of the inner cavity of the trolley frame 22. A hydraulic cylinder fixing shaft 26 is fixedly connected to the inner cavity of the trolley frame 22 on the side of the single hook shaft 25. A double hook shaft 27 is fixedly connected to the other side of the inner cavity of the trolley frame 22. A hydraulic cylinder drive shaft 28 is fixedly connected to the inner cavity of the trolley frame 22 on the side of the double hook shaft 27. Single plate hooks 29 are movably connected to the outer periphery of both the single hook shaft 25 and the double hook shaft 27. Synchronous connecting rods 210 are movably connected to the top of the two single plate hooks 29. Multiple single plate hooks 29 connected to the surface of the double hook shaft 27 are movably connected to the top of the single plate hooks 29. Link 211, synchronous link 210 and multi-link 211 adopt a box-type structure design to reduce weight while ensuring strength. The other end of multi-link 211 is movably connected to hydraulic cylinder drive shaft 28. A first hydraulic cylinder 212 is movably connected between hydraulic cylinder fixed shaft 26 and hydraulic cylinder drive shaft 28. Lifting lugs 31 matching single plate hook 29 are fixedly connected to both sides of the top of cover plate 3. Lifting lugs 31 provide gripping points for cover plate 3. Limit hooks 32 are fixedly connected to the front and rear ends of both sides of cover plate 3. The first hydraulic cylinder 212, the second hydraulic cylinder 213 and the identification module are all connected to the control module. The identification module is set above ladle 12.

[0030] Furthermore, a first pin 214 is connected through the single hook shaft 25 and the single plate hook 29. A first baffle 215 is inserted into one side of the first pin 214, and a first fastener 216 is threadedly connected to the single hook shaft 25 on the other side of the first baffle 215. The combination design of the first pin 214 and the first baffle 215 facilitates the installation and disassembly of the single plate hook 29. When disassembling, first unscrew the first fastener 216, then remove the first baffle 215 to release the axial limit of the first pin 214, and then remove the first pin 214 to disassemble the single plate hook 29.

[0031] Furthermore, in the automatic ladle capping device of this utility model, a first bearing 217 is sleeved on the outer periphery of the first pin 214, a grease cup 218 is provided through one end of the first pin 214, a first retaining ring 219 is sleeved on the other end of the first bearing 217, and positioning rings 220 are respectively sleeved on the outer periphery of the first pin 214 and at the front and rear ends of the first bearing 217. The other side of the positioning ring 220 contacts the single hook shaft 25, and the single plate hook 29 is sleeved on the outer periphery of the first bearing 217. The first retaining ring 219 can effectively prevent the axial movement of the first pin 214 and ensure the reliability of the connection. The first bearing 217 can limit the swing of the single plate hook 29 within a certain range, compensate for installation errors, and improve the success rate of grabbing the cover plate 3.

[0032] In one specific embodiment, in the automatic ladle capping device of this utility model, the first bearing 217 is a radial spherical bearing, and the first retaining ring 219 is an elastic retaining ring for A-type holes.

[0033] Furthermore, in the automatic ladle capping device of this utility model, both ends of the hydraulic cylinder drive shaft 28 and the double hook shaft 27 are threadedly connected to a second fastener 221. A second baffle 222 is threadedly connected to the outer periphery of the second fastener 221. A second pin 223 is threadedly connected to the other side of the second baffle 222 through the second fastener 221. A second bearing 224 is sleeved on the outer periphery of the second pin 223. A second retaining ring 225 is sleeved on the outer periphery of the second pin 223 and on one side of the second bearing 224. The other end of the second pin 223 is fixedly connected to the trolley frame 22 through a first fastener 216.

[0034] In one specific embodiment, in the automatic ladle capping device of this utility model, the second bearing 224 is a radial spherical bearing, and the second retaining ring 225 is an elastic retaining ring for A-type holes.

[0035] As a specific implementation, in the automatic ladle capping device of this utility model, both the front and rear ends of the ladle 12 are fixedly connected with limiting rods 13 that match the limiting hooks 32. The limiting rods 13 cooperate with the limiting hooks 32 on the cover plate 3 to achieve pre-positioning of the cover plate 3 during installation, improve the capping accuracy, effectively prevent the cover plate 3 from shifting, and ensure accurate positioning and locking during capping.

[0036] The working principle of the automatic ladle capping device of this utility model is as follows:

[0037] This device is controlled by a control module. The position of the ladle 12 is identified by an identification module. When the ladle 12 reaches the designated capping position, the identification module sends a signal to the control module, which then issues a command to control the second hydraulic cylinder 213 to drive the trolley frame 22 to slide along the track 21 above the ladle 12. The first hydraulic cylinder 212 is then controlled to rotate the single-plate hook 29 through the multi-link 211 mechanism, so that it engages with the lifting lug 31 on the cover plate 3. Subsequently, the second hydraulic cylinder 213 is controlled to move in the opposite direction, lifting and translating the cover plate 3 directly above the ladle 12. The first hydraulic cylinder 212 is controlled again to release the single-plate hook 29 from the lifting lug 31. The cover plate 3 falls under its own weight, and the limit hook 32 cooperates with the limit rod 13 on the ladle 12 to complete the precise positioning and realize the capping action. The entire process is precisely controlled by the control module to control the stroke and timing of each hydraulic cylinder, ensuring that the capping action is efficient, stable, and reliable.

[0038] In summary, compared with the prior art, the automatic ladle capping device of this utility model has the following advantages and beneficial effects:

[0039] (1) This device is controlled by the control module to realize the full automation of the ladle 12 capping process, replacing the traditional manual operation. The trolley frame 22 of the capping component 2 slides along the track 21. With the help of the multi-link 211 mechanism driven by the hydraulic cylinder, the capping plate 3 can be accurately grasped, transported and capped. The sliding cooperation design of the wheels and the track 21 ensures smooth operation and accurate positioning. Compared with manual operation, the capping efficiency is greatly improved. At the same time, it avoids the operator from being exposed to high temperature and dust environment, significantly reducing safety risks. The logic control of the control module can also automatically adjust the capping time according to the production rhythm, reduce the temperature fluctuation of molten steel and improve the subsequent casting quality.

[0040] (2) This device adopts a unique single-plate hook 29 and lifting lug 31 cooperation structure, combined with the dual positioning design of limit rod 13 and limit hook 32 to ensure the precise docking of cover plate 3 and steel ladle 12. The linkage mechanism of single hook shaft 25, double hook shaft 27 and synchronous connecting rod 210 keeps cover plate 3 balanced during the grabbing and putting down process, avoiding shaking or deviation. The drive design of the first hydraulic cylinder 212 provides sufficient grabbing force to prevent cover plate 3 from falling off. The second hydraulic cylinder 213 controls the translation of trolley frame 22 to realize the rapid covering action. The device as a whole can adapt to harsh working conditions such as high temperature and vibration, and has a low failure rate.
