[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figures 3 to 7 To achieve the above purpose, the utility model provides the following technical solutions:

[0025] A novel molten iron ladle tilting device comprises a molten iron ladle transport vehicle 1, on which a tilting frame 2 is installed, wherein a trunnion-free ladle body 3 is arranged inside the tilting frame 2; two rotating supports 4 are symmetrically arranged on both sides of the molten iron ladle transport vehicle 1, wherein the two rotating supports 4 are movably connected to the outer walls of both sides of the tilting frame 2 respectively; a limit seat 5 is provided at one end of the molten iron ladle transport vehicle 1 close to the rotating support 4, wherein a position sensor 6 is provided at the top of the limit seat 5.

[0026] By placing the trunnion-free tank body 3 inside the tilting frame 2, driving the molten iron ladle transport vehicle 1 to the specified position, the tail shaft 8 of the tilting frame 2 is hooked by the hydraulic plate hook 7 and lifted upward, so that the trunnion-free tank body 3 rotates with the tilting frame 2 with the rotating shaft 10 installed on the rotating support 4 as the rotation center. During the rotation of the tilting frame 2, the rotating support 4 provides it with stable support and flexible rotation function, so that the tilting frame 2 can tilt smoothly and accurately; by arranging a limit seat 5 at one end of the molten iron ladle transport vehicle 1 close to the rotating support 4, and installing a position sensor 6 on the limit seat 5, it is used to monitor the position and tilting angle of the tilting frame 2 in real time. When the tilting frame 2 reaches the preset tilting angle, the position sensor 6 will send a signal to the control module (not shown), so that the control module can accurately control the further action of the tilting frame 2 according to the received signal, thereby realizing a safe and efficient tilting operation of the trunnion-free tank body 3, which not only improves the production efficiency in the steel smelting process, but also greatly reduces the labor intensity and safety risks of the operators.

[0027] It should be noted that the control module described in this embodiment has been disclosed in the prior art and is common knowledge to those skilled in the art and does not need to be described again.

[0028] Please refer to Figures 5 to 7As an embodiment of the utility model, the rotating support 4 includes a base 401, the lower end of the base 401 is fixedly connected to the molten iron ladle transport vehicle 1, wherein the upper end of the base 401 is fixedly connected to the upper seat 402 by bolts 403; the upper seat 402 and the base 401 are spliced ​​to form a mounting hole 404, wherein a self-lubricating bearing 405 is provided in the mounting hole 404.

[0029] In the above-described scheme, the lower end of the base 401 is firmly fixed to the molten iron ladle transport vehicle 1, ensuring the stability of the entire rotating support 4, wherein the upper end of the base 401 is fixedly connected to the upper seat 402 by bolts 403, and this connection method not only ensures the strength of the rotating support 4, but also facilitates installation and disassembly; a mounting hole 404 is formed between the base 401 and the upper seat 402, wherein a self-lubricating bearing 405 is arranged inside the mounting hole 404, and the self-lubricating bearing 405 has a self-lubricating function and can be used without external lubrication. It maintains a good lubrication state under slippery conditions, thereby reducing friction and wear, and improving the durability and service life of the rotating support 4; when the tilting frame 2 is tilting, the tilting frame 2 rotates relative to the self-lubricating bearing 405 in the rotating support 4 through the rotating shaft 10, wherein the self-lubricating bearing 405 greatly reduces the friction resistance during the rotation process, so that the tilting frame 2 can tilt more smoothly and stably. At the same time, the self-lubricating bearing 405 can also withstand larger radial and axial loads, ensuring the safety and stability of the tilting process.

[0030] Please refer to Figure 3 , Figure 4 As an embodiment of the utility model, a tail shaft 8 for movably connecting with a hydraulic plate hook 7 is provided at one end of the tilting frame 2, wherein an arc-shaped rotating surface 9 is provided at the end of the tilting frame 2 away from the tail shaft 8; the cross-section of the tilting frame 2 is a box beam structure, wherein the bottom of the tilting frame 2 is horizontally arranged and fits with the upper end surface of the molten iron ladle transport vehicle 1.

[0031] In the above-mentioned scheme, a tail shaft 8 is provided at one end of the tilting frame 2, wherein the tail shaft 8 is used to be movably connected with the hydraulic plate hook 7. When the hydraulic plate hook 7 applies an upward pulling force, the tail shaft 8 is used as a force point to drive the tilting frame 2 to rotate, which not only ensures that the tilting frame 2 can be flexibly tilted, but also ensures the stability and safety of the connection; by providing an arc-shaped rotating surface 9 at one end of the tilting frame 2 away from the tail shaft 8, wherein the arc-shaped rotating surface 9 cooperates with the self-lubricating bearing 405 on the rotating support 4, when the tilting frame 2 is tilted, the tail shaft 8 is used to drive the tilting frame 2 to rotate. During the tipping operation, the arc-shaped rotating surface 9 will rotate smoothly under the support of the self-lubricating bearing 405, which not only reduces the friction resistance during the tipping process, but also improves the stability and durability of the tipping frame 2; the cross-section of the tipping frame 2 is a box beam structure with high strength and rigidity, which can withstand the weight of the molten iron ladle and the molten iron therein, ensuring that no deformation or damage occurs during the tipping process. At the same time, the bottom of the tipping frame 2 is horizontally arranged and fits tightly with the upper end surface of the molten iron ladle transport vehicle 1, further enhancing the stability of the tipping frame 2.

[0032] Please refer to Figures 4 to 7 As an embodiment of the utility model, the outer walls of both sides of the tilting frame 2 close to one end of the arc-shaped rotating surface 9 are symmetrically installed with rotating shafts 10, wherein the rotating shaft 10 is adapted to the self-lubricating bearing 405; the outer wall of the top end of the rotating shaft 10 is provided with an external thread, wherein the top end of the rotating shaft 10 passes through the self-lubricating bearing 405 and is screwed and connected with a fastening nut 11.

[0033] In the above-described scheme, the rotating shaft 10 is symmetrically installed on the outer walls of both sides of the tilting frame 2 to ensure the balance and stability of the tilting frame 2 during the rotation process, wherein the rotating shaft 10 is adapted to the self-lubricating bearing 405 in the rotating support 4. When the tilting frame 2 rotates, the rotating shaft 10 rotates inside the self-lubricating bearing 405. Since the self-lubricating bearing 405 has the characteristic of self-lubrication, the rotating shaft 10 can reduce friction and wear during the rotation process, thereby ensuring the smooth tilting action; the outer wall of the top end of the rotating shaft 10 is provided with an external thread to be screwed with the fastening nut 11. When the top end of the rotating shaft 10 penetrates After the self-lubricating bearing 405 is installed, the fastening nut 11 is tightened on the top of the rotating shaft 10, so that the rotating shaft 10 is firmly fixed on the rotating support 4. This connection method not only ensures the stable connection between the rotating shaft 10 and the rotating support 4, but also facilitates the installation and disassembly operations; during the tipping process, the cooperation between the rotating shaft 10 and the self-lubricating bearing 405 enables the tipping frame 2 to rotate with less resistance. At the same time, the fastening nut 11 ensures that the rotating shaft 10 will not loosen or fall off due to the action of the tipping force, thereby ensuring the safety and reliability of the tipping process, and further providing a strong guarantee for the smooth operation of the entire tipping device.
