Description

Technical Field

[0001] This application relates to the technical field of ladle turning equipment, and in particular to ladle turning devices. Background Technology

[0002] A ladle is a core piece of equipment in the metallurgical industry used for holding and transferring molten steel at high temperatures. A ladle tilting device is used after the ladle has been transferred to receive it, facilitating its tilting and the emptying of the molten steel.

[0003] The existing ladle turning device is an integrated design, which results in a large overall size of the turning device, making it inconvenient to transport and difficult to produce. Utility Model Content

[0004] The purpose of this application is to provide a ladle turning device that has the advantages of allowing individual production and assembly of each component, easy disassembly and installation of the hooks, significantly reducing the space occupied by the turning device during transportation, and facilitating the disassembly and transportation of the ladle turning device. This solves the problem that the existing ladle turning devices are designed as a single unit, resulting in a large overall size of the turning device, which is inconvenient for transportation and difficult to produce.

[0005] The ladle turning device provided in this application adopts the following technical solution: The ladle turning device includes a steel frame body, the steel frame body includes a support plate, a connecting frame is fitted on the outer surface of the middle part of the support plate, the inner side of the connecting frame is fixedly welded to the outer surface of the middle part of the support plate, two sets of connecting plates are fixedly welded to both ends of the bottom of the connecting frame, each set of the connecting plates consists of two, a hook is installed between the two connecting plates in the same set, the same pin is inserted into the insertion hole of the two connecting plates in the same set and the insertion hole of the hook, and a lifting lug is fixedly welded to the top of the connecting frame.

[0006] By adopting the above technical solution, the support plate and the connecting frame together form the main frame of the steel frame. The support plate and the connecting frame can be processed and welded separately. The hooks can be easily installed and disassembled between the two connecting plates in the same group by means of pins. This greatly reduces the space occupied by the turning device during transportation and makes it easy to disassemble and transport the ladle turning device.

[0007] Preferably, one side of the support plate is provided with a plurality of reinforcing ribs, one side of the reinforcing ribs is fixedly welded to one side of the support plate, and both ends of the reinforcing ribs are fixedly welded to the top and bottom of the inner side of the connecting frame.

[0008] By adopting the above technical solution, the stiffening ribs connecting the support plate and the connecting frame can enhance the connection strength between the support plate and the connecting frame, preventing deformation or damage to the connection part of the support plate and the connecting frame due to excessive force during the process of receiving and turning the steel ladle. This improves the overall structural strength and service life of the steel frame body. Furthermore, the setting of the stiffening ribs can ensure the structural strength of the steel frame body while reducing the overall thickness of the steel frame body, thus saving the materials used in the steel frame body.

[0009] Preferably, the support plate has multiple through-holes in the middle, and the pin is inserted into the inside of the through-holes.

[0010] By adopting the above technical solution, the storage holes can be used to store the pins during the disassembly and transportation of the ladle turning device, preventing the pins from being lost during transportation. The ladle turning device will cause high-intensity wear on the pins during operation, making them prone to damage. By opening multiple storage holes, spare pins can be stored on the main body of the steel frame. When the pins connecting the hooks and corresponding connecting plates wear out after long-term use, the spare pins in the storage holes can be easily taken out and replaced, avoiding affecting the ladle turning operation.

[0011] Preferably, a fixing plate is fixedly provided at one end of the pin shaft, and the fixing plate at one end of the pin shaft in the receiving hole is fixedly connected to one side of the support plate by fastening bolts. The fixing plate at one end of the pin shaft inserted into the connecting plate insertion hole is fixedly connected to one side of the corresponding connecting plate by fastening bolts.

[0012] By adopting the above technical solution, the cooperation between the fixing plate and the fastening bolts can fix the pin in the corresponding storage hole and the insertion hole of the connecting plate respectively, preventing the pin from falling out of the storage hole or the insertion hole of the connecting plate and the hook during transportation or use, ensuring the reliability of the pin connection and the stability of storage, and further improving the safety of the device.

[0013] Preferably, a positioning frame is fixedly welded to one side of the support plate at the position corresponding to the storage hole, and a positioning frame is fixedly welded to one side of one of the two connecting plates in the same group. The positioning frame on one side of the support plate and the positioning frame on one side of the connecting plate have the same specifications. A fixing plate is inserted into the inner side of the positioning frame, and the specifications of the inner side of the positioning frame are adapted to the specifications of the outer surface of the middle part of the fixing plate.

[0014] By adopting the above technical solution, the positioning frame can play a positioning role in the installation of the fixing plate, and can quickly position the installation angle of the fixing plate, so that the bolt mounting holes of the fixing plate can be quickly aligned with the bolt mounting holes on the side of the connecting plate or the side of the support plate. It can be convenient to use fastening bolts to fix the installation position of the fixing plate, and improve the operational efficiency of pin installation and storage.

[0015] Preferably, one end of the pin has a through-hole, and a limiting pin is inserted into the inside of the limiting hole.

[0016] By adopting the above technical solution, the cooperation between the limiting hole and the limiting pin can play a double limiting role for the pin shaft, preventing the pin shaft from slipping out of the insertion hole of the connecting plate due to the vibration of the device during use, thus avoiding the separation of the hook from the connecting plate due to the pin shaft falling off, thereby ensuring the safety and stability of the ladle during the flipping process.

[0017] Preferably, a limiting block is fixedly provided at one end of the limiting pin, and the size of the limiting block is larger than the size of the limiting hole.

[0018] By adopting the above technical solution, the limiting block can prevent the limiting pin from falling out of the limiting hole, ensuring that the limiting pin's limiting effect on the pin shaft remains effective and avoiding the loss of the limiting function on the pin shaft due to the falling of the limiting pin, thus further improving the safety of the device.

[0019] Preferably, a positioning block is fixedly provided on one side of the fixing plate, and a limiting frame is fixedly provided on one side of the positioning frame corresponding to the position of the positioning block, and the positioning block is inserted into the inner wall of the limiting frame.

[0020] By adopting the above technical solution, the positioning block and the limiting frame can limit the installation angle of the fixing plate, thereby limiting the installation angle of the pin. The installation of the pin can then limit the orientation of the limiting hole, ensuring that the limiting hole is always installed with the pin facing vertically. This ensures that the limiting pin is always inserted into the limiting hole in the vertical direction. Furthermore, the limiting block at one end of the limiting pin can stably limit the pin, preventing the pin from slipping out of the limiting hole if it is installed horizontally.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This ladle turning device consists of a support plate and a connecting frame forming the main steel frame. The support plate and connecting frame can be processed and welded separately. The device can be installed and disassembled by using pins and hooks between two connecting plates in the same group, which greatly reduces the space occupied by the turning device during transportation and allows for easy disassembly and transportation of the ladle turning device.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: Ladle Tilting Device, please refer to Figure 1 , Figure 2 and Figure 4 The system includes a steel frame body 1, which includes a support plate 101. A connecting frame 102 is fitted onto the outer surface of the middle part of the support plate 101. The inner side of the connecting frame 102 is fixedly welded to the outer surface of the middle part of the support plate 101. Two sets of connecting plates 2 are fixedly welded to both ends of the bottom of the connecting frame 102. Each set of connecting plates 2 consists of two plates. A hook 3 is installed between the two connecting plates 2 in the same set. The same pin 4 is inserted into the insertion holes of the two connecting plates 2 in the same set and the insertion holes of the hook 3. A lifting lug 5 is fixedly welded to the top of the connecting frame 102.

[0026] Please see Figure 1 , Figure 2 and Figure 5 The support plate 101 has multiple reinforcing ribs 103 on one side. One side of the reinforcing ribs 103 is fixedly welded to one side of the support plate 101, and the two ends of the reinforcing ribs 103 are fixedly welded to the top and bottom of the inner side of the connecting frame 102. The reinforcing ribs 103 connect the support plate 101 and the connecting frame 102, which can enhance the connection strength between the support plate 101 and the connecting frame 102. This prevents the connection between the support plate 101 and the connecting frame 102 from deforming or being damaged due to excessive force during the process of receiving the steel ladle and turning it over. This improves the overall structural strength and service life of the steel frame body 1. Furthermore, the setting of the reinforcing ribs 103 can ensure the structural strength of the steel frame body 1 while reducing the overall thickness of the steel frame body 1, which can save the materials used in the steel frame body 1.

[0027] Please see Figure 1 , Figure 4 and Figure 5The support plate 101 has multiple through storage holes 12 in the middle. The pin 4 is inserted into the storage hole 12. The storage hole 12 can be used to store the pin 4 when the ladle flipping device is disassembled and transported, so as to avoid the pin 4 being lost during transportation. The ladle flipping device will cause high-intensity wear on the pin 4 during operation, and the pin 4 is prone to damage. The multiple storage holes 12 can store spare pins 4 on the steel frame body 1. When the pin 4 of the connecting hook 3 and the corresponding connecting plate 2 wears out after long-term use, the spare pin 4 in the storage hole 12 can be easily taken out and replaced to avoid affecting the ladle flipping operation.

[0028] Please see Figure 1 , Figure 2 and Figure 4 A fixing plate 6 is fixedly installed at one end of the pin 4. The fixing plate 6 at one end of the pin 4 in the storage hole 12 is fixedly connected to one side of the support plate 101 by fastening bolts 7. The fixing plate 6 at one end of the pin 4 inserted into the insertion hole of the connecting plate 2 is fixedly connected to one side of the corresponding connecting plate 2 by fastening bolts 7. The cooperation between the fixing plate 6 and the fastening bolts 7 can fix the pin 4 in the corresponding storage hole 12 and the insertion hole of the connecting plate 2 respectively, preventing the pin 4 from falling out of the storage hole 12 or the insertion hole of the connecting plate 2 and the hook 3 during transportation or use, ensuring the reliability of the pin 4 connection and the stability of storage, and further improving the safety of the device.

[0029] Please see Figure 1 , Figure 2 and Figure 4 One end of the pin 4 is provided with a through-hole 8, and a limit pin 9 is inserted into the inside of the limit hole 8. The cooperation between the limit hole 8 and the limit pin 9 can play a double limiting role for the pin 4, preventing the pin 4 from slipping out of the insertion hole of the connecting plate 2 due to the vibration of the device during use, and avoiding the hook 3 from separating from the connecting plate 2 due to the pin 4 falling off, thereby ensuring the safety and stability of the ladle during the flipping process.

[0030] Please see Figure 2 , Figure 3 and Figure 4 A limiting block 10 is fixedly provided at one end of the limiting pin 9. The size of the limiting block 10 is larger than that of the limiting hole 8. The limiting block 10 can prevent the limiting pin 9 from falling out of the limiting hole 8, ensuring that the limiting effect of the limiting pin 9 on the pin 4 is continuously effective, avoiding the loss of the limiting effect on the pin 4 due to the falling of the limiting pin 9, and further improving the safety of the device.

[0031] Example 2: Ladle Tilting Device, please refer to [link / reference] Figure 1 , Figure 2 and Figure 4A positioning frame 11 is fixedly welded to one side of the support plate 101 at the position corresponding to the storage hole 12. A positioning frame 11 is also fixedly welded to one side of one of the two connecting plates 2 in the same group. The positioning frame 11 on one side of the support plate 101 has the same specifications as the positioning frame 11 on one side of the connecting plate 2. A fixing plate 6 is inserted into the inner side of the positioning frame 11. The specifications of the inner side of the positioning frame 11 are compatible with the specifications of the outer surface of the middle part of the fixing plate 6. The positioning frame 11 can play a positioning role in the installation of the fixing plate 6, and can quickly position the installation angle of the fixing plate 6 so that the bolt mounting holes of the fixing plate 6 can be quickly aligned with the bolt mounting holes on one side of the connecting plate 2 or the bolt mounting holes on one side of the support plate 101. The fixing plate 6 can be easily fixed in place by using the fastening bolts 7, which improves the efficiency of the installation and storage of the pin shaft 4.

[0032] Please see Figure 1 , Figure 2 and Figure 4 A positioning block 13 is fixedly installed on one side of the fixing plate 6, and a limiting frame 14 is fixedly installed on one side of the positioning frame 11 corresponding to the position of the positioning block 13. The positioning block 13 is inserted into the inner wall of the limiting frame 14. The positioning block 13, together with the limiting frame 14, can limit the installation angle of the fixing plate 6, thereby limiting the installation angle of the pin 4. The installation of the pin 4 can then limit the orientation of the limiting hole 8, ensuring that the limiting hole 8 is always installed with a vertical through-hole orientation. This ensures that the limiting pin 9 is always inserted into the limiting hole 8 in a vertical direction. The limiting block 10 at one end of the limiting pin 9 can then stably limit the limiting pin 9, preventing the limiting hole 8 from being installed horizontally and causing the limiting pin 9 to easily slip out of the limiting hole 8.

[0033] The implementation principle of this application embodiment is as follows: During production, the support plate 101, connecting frame 102, and reinforcing rib plate 103 of the steel frame body 1 are produced separately. The connecting frame 102 is fitted onto the outer side of the middle part of the support plate 101 and the two are welded together. The reinforcing rib plate 103 is welded between one side of the support plate 101 and the inner side of the connecting frame 102 to reinforce the connection between the connecting frame 102 and the support plate 101, thus forming the steel frame body 1. The lifting lug 5 is welded to the top of the connecting frame 102, and two sets of connecting plates 2 are welded to both ends of the bottom of the connecting frame 102. When transporting the ladle turning device, the hook 3 is transported separately from the assembled steel frame body 1 and the accessories welded to the steel frame body 1 to avoid the installation and assembly of the hook 3 and the steel frame body 1 occupying a large amount of transportation space. During transportation, the pin 4 is inserted into the storage hole 12, and the fixing plate 6 at one end of the pin 4 is fixed to one side of the support plate 101 using fastening bolts 7. The hook 3 is then assembled with the steel frame body 1. At this time, remove the fastening bolts 7 between the fixing plate 6 and the support plate 101, take out the pin 4 from the storage hole 12, insert one end of the hook 3 into the two connecting plates 2 in the same group, and use the pin 4 to insert into the insertion hole of the hook 3 and the insertion hole of the two connecting plates 2 in the same group to connect the hook 3 and the two connecting plates 2 in the same group. At the same time, insert the fixing plate 6 at one end of the pin 4 into the positioning frame 11 on one side of the connecting plate 2, and simultaneously insert the positioning block 13 on one side of the fixing plate 6 into the positioning frame 11. Within the limiting frame 14 on one side, the installation angle of the pin 4 is fixed. The fixing plate 6 is fixed to one side of the corresponding connecting plate 2 using the fastening bolt 7. The limiting pin 9 is inserted into the limiting hole 8 from above to complete the assembly between the hook 3 and the steel frame body 1. When the pin 4 on the hook 3 is worn and affects the working condition, the pin 4 between the hook 3 and the connecting plate 2 is removed. The pin 4 in the storage hole 12 is removed and installed into the insertion hole between the hook 3 and the connecting plate 2 for replacement.
