Description

Technical Field

[0001] This invention relates to the field of molten metal transfer equipment, specifically a safe ladle for transferring molten iron with a highly efficient heat preservation and leak-proof structure. Background Technology

[0002] In the field of traditional casting molten iron transfer and pouring technology, there are many problems that urgently need to be solved. On the one hand, the heat preservation performance is poor, and the molten iron loses a lot of heat during the transfer process, resulting in a decrease in the temperature of the molten iron and a decrease in its fluidity, which affects the quality of subsequent pouring and may even cause casting defects and reduce the product qualification rate. On the other hand, the leakage prevention measures are not perfect, and molten iron is easy to leak out of the ladle, which not only wastes molten iron and increases production costs, but also poses a serious safety threat to operators and surrounding equipment. In addition, the existing ladle lifting and rotating structure is not stable and flexible enough. Shaking and deviation are prone to occur during the lifting process, which affects the normal operation of the heat preservation components. The rotating operation mode is simple and lacks the function of switching between electric and manual. Once the electric equipment fails or there is a power outage, the molten iron transfer task cannot be completed, which seriously affects the continuity of production. Moreover, the structural design of traditional ladles lacks flexibility and is difficult to adapt to the needs of different production scenarios for molten iron storage and transfer methods. Summary of the Invention

[0003] The purpose of this invention is to provide a safe transfer ladle for molten iron with a highly efficient heat preservation and leak-proof structure, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a safe transfer ladle for molten iron with a high-efficiency heat preservation and leak-proof structure, comprising a storage tank, two U-shaped steels symmetrically arranged on the side of the storage tank, and a hanging assembly on the U-shaped steels. The hanging assembly includes two mounting plates and two connecting plates, both of which are fixed to the U-shaped steels at corresponding positions. A connecting shaft one and a connecting shaft two are respectively fixed on the two connecting plates. A slewing bearing is fixed on both mounting plates, and the connecting shaft one and the connecting shaft two are respectively disposed inside the slewing bearings at corresponding positions. A horizontal plate is fixed above the two mounting plates, and a fixing plate is fixed between the horizontal plate and the two mounting plates. An H-beam is fixed above the horizontal plate, and a hanging plate is fixed above the H-beam. A hanging hole is provided on the top of the hanging plate. A lifting assembly is provided on the two mounting plates, and a heat preservation assembly is provided below the lifting assembly. A rotating assembly is provided on the side of one of the mounting plates.

[0005] The mounting plate is provided with sliding groove one and sliding groove two respectively.

[0006] Using the above structure, sliding groove one and sliding groove two provide precise tracks for the movement of sliding block one and sliding block two, respectively. The limiting rod is fixed in sliding groove one, guiding and limiting the sliding block one, ensuring that sliding block one can only move linearly along the axis of the limiting rod. The threaded rod is rotatably set in sliding groove two. When the threaded rod rotates, because sliding block two is threadedly connected to the threaded rod, and under the limiting effect of sliding groove two, sliding block two will move linearly along the axis of the threaded rod. The side plate, cylinder, fixing rod, and fixing block connect sliding block one and sliding block two into an integral motion frame. When sliding block one and sliding block two move, they can drive the entire frame to move together, providing stable support and motion transmission structure for the subsequent lifting and lowering of the insulation component, effectively reducing swaying and deviation during the movement. The limiting rod ensures the movement direction of sliding block one, improving the reliability of the movement. The overall frame structure enhances the stability of the lifting component, providing a strong guarantee for the normal operation of the insulation component.

[0007] The storage tank is equipped with an arc-shaped nozzle and a connecting ring one. An expansion tank is located below the storage tank, and a connecting ring two is located on the expansion tank. The connecting ring one and the connecting ring two are fixedly connected. A counterweight is detachably installed at the bottom of the expansion tank. The storage tank and the expansion tank are equipped with heat-insulating liners.

[0008] With the above structure, the arc-shaped nozzle design on the storage tank conforms to the principles of fluid dynamics, allowing molten iron to flow out more smoothly when poured. The fixed connection of connecting ring one and connecting ring two combines the storage tank and the expansion tank together. The expansion tank increases the storage capacity of molten iron. The counterweight can be disassembled and installed according to actual conditions to adjust the center of gravity of the ladle and ensure stability during transportation. The heat-insulating lining is made of high-temperature resistant and leak-proof materials, which can effectively prevent molten iron leakage and ensure operational safety. The setting of the expansion tank and counterweight increases the applicability and flexibility of the ladle and can meet the needs of different production scenarios. The heat-insulating lining effectively prevents molten iron leakage, improves the safety and reliability of the equipment, and reduces safety hazards and economic losses caused by molten iron leakage.

[0009] The lifting assembly includes a limiting rod and a threaded rod. The limiting rod is fixed inside the first sliding groove. A first sliding block is slidably disposed on the limiting rod and inside the first sliding groove. The threaded rod is rotatably disposed inside the second sliding groove. A second sliding block is threadedly connected to the threaded rod and inside the second sliding groove. Side plates are fixed on both sides of the first and second sliding blocks. A cylinder is fixed on the side plate. A fixing rod is fixed between two cylinders on the same side. A fixing block is fixed at the end of the two cylinders on the same side.

[0010] Using the above structure, the fixed relationship between the limiting rod and the sliding groove one provides a stable guiding foundation for the movement of the sliding block one. When the lifting assembly is driven by power, the sliding block one slides linearly in the sliding groove one along the axial direction of the limiting rod. The existence of the limiting rod ensures that the sliding block one can only move along a specific linear direction, avoiding deviation or shaking during movement and ensuring the accuracy of the movement. The threaded rod is rotatably set in the sliding groove two. When the threaded rod is driven by external power to rotate, since the sliding block two and the threaded rod are connected by a thread, and the sliding block two is limited by the sliding groove two, it can only move along the axial direction of the sliding groove two. According to the principle of thread transmission, the rotational motion of the threaded rod will be converted into the linear motion of the sliding block two, causing it to move axially in the sliding groove two. The side plates fixed on both sides of the sliding block one and the sliding block two play a connecting and supporting role. The cylinders fixed on the side plates further provide installation positions for the fixing rod and the fixing block. The two cylinders on the same side The fixed rod enhances the stability of the overall structure, allowing sliding block one and sliding block two to move as a whole. The fixed blocks at the ends of the two cylinders on the same side can be used to connect other components, such as the insulation component, transmitting the movement of the lifting component to the insulation component to realize the lifting function of the insulation component. The cooperative design of the limit rod and sliding groove one makes the movement of sliding block one more stable and accurate, effectively reducing friction and deviation during the movement process, and improving the movement accuracy and reliability of the lifting component. The threaded transmission method of the threaded rod and sliding block two has a self-locking function. When the power source stops driving, sliding block two can remain in the current position and will not slide on its own due to gravity or other external forces, ensuring the stability of the insulation component during the lifting process. The overall connection structure composed of the side plate, cylinder, fixed rod and fixed block enhances the strength and stability of the lifting component, can better withstand the weight of the insulation component and various forces generated during the movement, and extend the service life of the equipment.

[0011] The threaded rod has a driven bevel gear fixed at its end. A rotating shaft is rotatably mounted on one of the mounting plates. A driving bevel gear is fixed at one end of the rotating shaft. The driving bevel gear and the driven bevel gear mesh. A fixing key is provided at the other end of the rotating shaft.

[0012] With the above structure, the handwheel is installed at the other end of the rotating shaft. When the operator turns the handwheel, it drives the rotating shaft to rotate. Similarly, through the meshing transmission of the driving bevel gear and the driven bevel gear, the threaded rod rotates. When the threaded rod rotates, the sliding block two, which is threaded to it, can only move linearly along the axial direction of the threaded rod. The sliding block two drives the entire lifting assembly to move through the relevant connection structure, realizing the lifting function. The meshing transmission of the bevel gears can accurately transmit power, ensuring that the threaded rod rotates at the predetermined speed and direction, making the lifting movement smooth and precise. At the same time, the bevel gear transmission has high efficiency, reducing power loss. The fixed key facilitates the disassembly and assembly of external power equipment, and the detachable design of the handwheel also facilitates the inspection and maintenance of components such as the rotating shaft and bevel gears, reducing maintenance difficulty and cost, and extending the service life of the equipment.

[0013] The insulation component includes an insulation cover, which is fixed on four cylinders. A feeding box is fixed on the top of the insulation cover. The feeding box has a liquid inlet hole one, and the insulation cover has a liquid inlet hole two. The liquid inlet hole one and the liquid inlet hole two are connected.

[0014] With the above structure, the insulation cover is fixed to four cylinders, tightly covering the top of the storage tank, forming a relatively sealed space. This effectively reduces heat exchange between the molten iron inside the storage tank and the outside air, thus reducing heat loss. The first liquid inlet on the feeding box is connected to the second liquid inlet on the insulation cover. When molten iron is injected into the storage tank, it can smoothly enter the storage tank through both inlets. This structural design not only facilitates the injection of molten iron but also ensures the sealing of the storage tank to a certain extent, helping to maintain the temperature of the molten iron. The insulation cover reduces heat loss during the transfer of molten iron, ensuring its temperature and fluidity, and improving its quality. The rational design of the feeding box and the liquid inlet makes the molten iron injection process smoother, improving operational efficiency, while reducing heat loss and splashing risks during injection, ensuring operational safety.

[0015] The rotating assembly includes a worm gear reducer, which is fixed on one of the mounting plates. The output shaft of the worm gear reducer is fixedly connected to a connecting shaft two. A one-way clutch is fixed to the side of the worm gear reducer. A motor is installed on the side of the one-way clutch and is connected to it for transmission. The output shaft of the one-way clutch is fixedly connected to the input shaft of the worm gear reducer. A handwheel is detachably installed on the one-way clutch.

[0016] With the above structure, the worm gear reducer is fixed on the mounting plate, and its output shaft is fixedly connected to the connecting shaft. This allows the input power to be reduced in speed and torque before being transmitted to the storage bucket, enabling the bucket to rotate and pour molten iron. The one-way clutch has a unidirectional transmission characteristic. When the motor starts, its power is transmitted to the worm gear reducer via the one-way clutch, driving the storage bucket to rotate. When the operator manually operates the machine using a handwheel, the handwheel's power is also transmitted to the worm gear reducer via the one-way clutch, allowing manual rotation of the storage bucket. Simultaneously, due to the one-way nature of the clutch, manual operation does not drive the motor, avoiding reverse impact on the motor. The worm gear reducer achieves power reduction and torque amplification, allowing the storage bucket to rotate at a suitable speed and torque, ensuring the smoothness and accuracy of molten iron pouring. The one-way clutch allows for free switching between electric and manual operation, improving the equipment's operational flexibility and reliability. In the event of motor failure or power outage, the molten iron transfer task can continue through manual operation, ensuring production continuity.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This safe transfer ladle for molten iron, featuring a highly efficient heat-insulating and leak-proof structure, effectively reduces heat loss during molten iron transfer, ensuring the temperature and fluidity of the molten iron and improving its quality. Simultaneously, it prevents leakage, guaranteeing operational safety. Its lifting and rotating functions are stable and reliable, and its flexible operation adapts to different production scenarios, enhancing the efficiency and quality of molten iron transfer and pouring while reducing production costs and safety risks.

[0022] Two mounting plates 12 are respectively provided with sliding groove 40 and sliding groove 36; sliding groove 40 and sliding groove 36 provide precise tracks for the movement of sliding block 30 and sliding block 35, respectively. A limiting rod 23 is fixed in sliding groove 40, guiding and limiting sliding block 30, ensuring that sliding block 30 can only move linearly along the axial direction of the limiting rod 23. A threaded rod 34 is rotatably mounted in sliding groove 36. When the threaded rod 34 rotates, because sliding block 35 is threadedly connected to the threaded rod 34, and under the limiting action of sliding groove 36, sliding block 35 will move along... The threaded rod 34 moves linearly along its axis. The side plate 24, cylinder 2, fixed rod 21, and fixed block 13 connect sliding block 30 and sliding block 35 into an integral moving frame. When sliding block 30 and sliding block 35 move, they can drive the entire frame to move together, providing stable support and motion transmission structure for the subsequent lifting and lowering of the insulation component, effectively reducing swaying and deviation during the movement. The limit rod 23 ensures the movement direction of sliding block 30, improving the reliability of the movement. The overall frame structure enhances the stability of the lifting component, providing a strong guarantee for the normal operation of the insulation component.

The arc-shaped nozzle 4 on the storage tank 31 is designed according to fluid dynamics principles, allowing the molten iron to flow out more smoothly when poured. The fixed connection of connecting rings 5 ​​and 20 connects the storage tank 31 and the expansion tank 26. When combined, the expansion tank 26 increases the storage capacity of molten iron, and the counterweight 19 can be disassembled and installed according to actual conditions to adjust the center of gravity of the ladle and ensure stability during transportation. The heat-insulating lining 32 is made of high-temperature resistant and leak-proof material, which can effectively prevent molten iron leakage and ensure operational safety. The setting of the expansion tank 26 and the counterweight 19 increases the applicability and flexibility of the ladle and can meet the needs of different production scenarios. The heat-insulating lining 32 effectively prevents molten iron leakage, improves the safety and reliability of the equipment, and reduces safety hazards and economic losses caused by molten iron leakage.

[0024] The lifting assembly includes a limiting rod 23 and a threaded rod 34. The limiting rod 23 is fixed inside the sliding groove 40. A sliding block 30 is slidably mounted on the limiting rod 23 inside the sliding groove 40. The threaded rod 34 is rotatably mounted inside the sliding groove 36.

A cylinder 2 is fixed on the side plate 24. A fixing rod 21 is fixed between the two cylinders 2 on the same side. A fixing block 13 is fixed at the end of the two cylinders 2 on the same side. The limiting rod 23 is fixed to the sliding groove 40 by the sliding block 34. The movement of 30 provides a stable guiding foundation. When the lifting assembly is driven by power, the sliding block 30 slides linearly within the sliding groove 40 along the axial direction of the limiting rod 23. The presence of the limiting rod 23 ensures that the sliding block 30 can only move along a specific linear direction, preventing it from deviating or wobbling during movement and ensuring the accuracy of the movement. The threaded rod 34 is rotatably set within the sliding groove 36. When the threaded rod 34 is driven to rotate by external power, because the sliding block 35 and the threaded rod 34 are connected by a thread, and the sliding block 35 is limited by the sliding groove 36, it can only move along the axial direction of the sliding groove 36. According to the principle of threaded transmission, the threaded rod 34... The rotational motion is converted into linear motion of the second sliding block 35, causing it to move axially within the second sliding groove 36. The side plates 24 fixed on both sides of the first sliding block 30 and the second sliding block 35 serve as a connection and support. The cylinders 2 fixed on the side plates 24 further provide installation positions for the fixing rods 21 and fixing blocks 13. The fixing rods 21 fixed between the two cylinders 2 on the same side enhance the stability of the overall structure, allowing the first sliding block 30 and the second sliding block 35 to move as a whole. The fixing blocks 13 fixed at the ends of the two cylinders 2 on the same side can be used to connect other components, such as the insulation component, transmitting the motion of the lifting component to the insulation component to realize the lifting function of the insulation component. The limit rods 23 and The design of the sliding groove 40 makes the movement of the sliding block 30 more stable and accurate, effectively reducing friction and deviation during the movement process, and improving the movement accuracy and reliability of the lifting assembly. The threaded transmission of the threaded rod 34 and the sliding block 35 has a self-locking function. When the power source stops driving, the sliding block 35 can remain in the current position and will not slide on its own due to gravity or other external forces, ensuring the stability of the insulation assembly during the lifting process. The overall connection structure composed of the side plate 24, cylinder 2, fixed rod 21 and fixed block 13 enhances the strength and stability of the lifting assembly, and can better withstand the weight of the insulation assembly and various forces generated during the movement, thus extending the service life of the equipment.

A fixing key 39 is provided at the other end of the rotating shaft 10. A handwheel 6 is installed at the other end of the rotating shaft 10. When the operator rotates the handwheel 6, the handwheel 6 drives the rotating shaft 10 to rotate. Similarly, through the meshing of the driving bevel gear 37 and the driven bevel gear 38, the threaded rod 34 rotates. When the threaded rod 34 rotates, due to the slippage of the threaded connection... The second moving block 35 can only move linearly along the axial direction of the threaded rod 34. The second sliding block 35 drives the entire lifting assembly to move through the relevant connection structure to realize the lifting function. The bevel gear meshing transmission can accurately transmit power, ensuring that the threaded rod 34 rotates at the predetermined speed and direction, making the lifting movement smooth and precise. At the same time, the bevel gear transmission has high efficiency, reducing power loss. The fixed key 39 facilitates the disassembly and assembly of external power equipment.

[0026] The insulation assembly includes an insulation cover 28, which is fixed to four cylinders 2. A feeding box 3 is fixed above the insulation cover 28. The feeding box 3 has a liquid inlet hole 29, and the insulation cover 28 has a liquid inlet hole 33. The liquid inlet hole 29 and the liquid inlet hole 33 are connected. The insulation cover 28 is fixed to the four cylinders 2, tightly covering the storage tank 31, forming a relatively sealed space, effectively reducing the heat exchange between the molten iron in the storage tank 31 and the outside air, thereby reducing heat loss. The liquid inlet hole 29 on the feeding box 3 is connected to the liquid inlet hole 33 on the insulation cover 28, allowing liquid to flow into the storage tank.

The worm gear reducer 9 drives the storage tank 31 to rotate. When the operator manually operates the device using the handwheel 6, the power from the handwheel 6 can also be transmitted to the worm gear reducer 9 through the one-way clutch 8, enabling manual rotation of the storage tank 31.

The worm gear reducer 9 achieves power reduction and torque amplification, allowing the storage tank 31 to rotate at a suitable speed and torque, ensuring the smoothness and accuracy of molten iron pouring. The one-way clutch 8 allows for free switching between electric and manual operation, improving the operational flexibility and reliability of the equipment. In the event of a motor 7 malfunction or power outage, the molten iron transfer task can continue through manual operation, ensuring production continuity.

[0028] Working principle: The ladle is lifted and transported to the molten iron loading area by connecting the external lifting equipment to the mounting holes 15 on the mounting plate 14. The molten iron is injected into the storage tank 31 and the expansion tank 26 through the liquid inlet hole 29 on the feeding box 3 and the liquid inlet hole 33 on the heat insulation cover 28. The heat insulation lining 32 prevents the molten iron from leaking, and the heat insulation cover 28 reduces the heat loss of the molten iron. When it is necessary to adjust the lifting components, if an electric method is used, the external power equipment is connected to the rotating shaft 10 through the fixing key 39. The power is transmitted to the rotating shaft 10 to make it rotate. The driving bevel gear 37 at one end of the rotating shaft 10 rotates accordingly, and drives the threaded rod by meshing with the driven bevel gear 38. Rotation of threaded rod 34 causes sliding block 35 to move axially within sliding groove 36, while sliding block 30 slides linearly within limit rod 23 and sliding groove 40. The two components are connected by side plate 24, cylinder 2, etc., to raise and lower the insulation component. If manual operation is used, handwheel 6 is installed at the other end of rotating shaft 10. Rotating handwheel 6 drives rotating shaft 10, which in turn rotates threaded rod 34 via bevel gear transmission, thus moving the lifting component. When molten iron needs to be poured, motor 7 starts, and power is transmitted to worm gear reducer 9 via one-way clutch 8. After reduction and torque amplification, the power is transmitted through output shaft and connecting shaft. The motor 27 drives the storage tank 31 to rotate, allowing molten iron to flow smoothly from the arc-shaped nozzle 4. If the motor 7 malfunctions, the handwheel 6 can be manually turned, transmitting power via the one-way clutch 8 to the worm gear reducer 9, enabling the storage tank 31 to be manually rotated to pour out the molten iron. The counterweight 19 can adjust the ladle's center of gravity to ensure stability. The design of the U-shaped steel 11 and the hanging components allows the ladle to be stably connected to the lifting equipment for easy transport. The expansion tank 26 and the counterweight 19 increase the ladle's applicability and flexibility, meeting the needs of different production scenarios. The heat-insulating lining 32 effectively prevents leakage and ensures operational safety. In the lifting components, the limit rod 23 and the sliding groove 40 are designed to ensure... The sliding block 30 moves smoothly and accurately. The threaded transmission of the threaded rod 34 and the sliding block 35 has a self-locking function, ensuring stable lifting of the insulation component. The bevel gear transmission is accurate and efficient, and facilitates the disassembly and maintenance of the power equipment. The insulation cover 28 of the insulation component reduces heat loss of molten iron and ensures the quality of molten iron. The design of the feed box 3 and the liquid inlet hole ensures smooth injection of molten iron, improves operating efficiency and ensures safety. In the rotating component, the worm gear reducer 9 realizes power reduction and torque increase, ensuring smooth and accurate pouring of molten iron. The one-way clutch 8 realizes free switching between electric and manual operation, improves the flexibility and reliability of equipment operation, and ensures continuous production.
