Description

Technical Field

[0001] This utility model relates to the field of steel production technology, specifically to a ladle reversing device. Background Technology

[0002] The ladle reversing operation is an indispensable and crucial link in the steel production process. Its operational safety and efficiency are directly related to the company's production benefits and the safety of personnel. However, the traditional operation mode has many safety hazards and its efficiency needs to be improved. In order to effectively eliminate these safety hazards and further improve operational efficiency, a technical transformation of the ladle reversing operation has been implemented. By innovating the operation process, the technical transformation has significantly improved the safety of the operation and also effectively improved production efficiency, but certain defects still exist.

[0003] The existing molten iron ladle reversing device has significant safety hazards and functional limitations during operation. When operating the device, the molten iron ladle must first be lifted up, and the operator must bend down and crawl under the suspended molten iron ladle, pass through the iron chain of the ladle by hand and hang it on the bushing to complete the reversing operation. This process not only faces direct safety risks such as falling heavy objects and entanglement of iron chains, but also has a complicated operation process and requires a high level of operator proficiency. Even a slight mistake may lead to a serious safety accident. Meanwhile, in pursuit of structural stability, existing devices often adopt an integrated design, which cannot be flexibly adjusted after installation. This often leads to problems such as tilting and insufficient stability when hoisting molten iron ladles of different sizes, due to the mismatch in the spacing between the hooks on both sides. In some cases, the devices may even become unusable, greatly limiting their applicability and making it difficult to meet diverse operational needs. Utility Model Content

[0016] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments: Example 1 like Figure 1-4As shown, this utility model provides a ladle reversing operation device, including a crane body 1. A connecting plate 2 is fixedly installed at one end of the crane body 1. A support frame 3 is fixedly installed at the bottom of the connecting plate 2. Several fixing rods 4 are fixedly installed at the top of the support frame 3, and two mounting frames 6 are fixedly installed at the bottom. Several positioning grooves 601 and locking grooves 602 are opened on the inner wall of the mounting frame 6, and a connecting component 7 is provided. The connecting component 7 includes a fixing seat 701, which abuts against both sides of the inner wall of the mounting frame 6 and can slide inside the mounting frame 6. A locking rod 705 is fixedly installed inside the fixing seat 701 for locking. A hook 8 is fixedly installed on the outer wall of the rod 705. The connecting assembly 7 also includes several positioning bolts 703 and locking bolts 704. A square groove 702 is opened on the outer wall of the fixing seat 701. Several positioning bolts 703 are threadedly connected to the fixing seat 701 and the positioning groove 601. Several locking bolts 704 are threadedly connected to the fixing seat 701 and the locking groove 602. The locking rod 705 passes through the outer wall of the fixing seat 701, and a fastening nut 706 is threadedly sleeved on the outer wall. Several positioning grooves 601 are equidistantly arranged on the inner wall of the mounting frame 6. Several locking grooves 602 are equidistantly arranged on the outer wall of the mounting frame 6 and pass through the mounting frame 6.

[0017] In this embodiment, the positioning groove 601 and locking groove 602 of the mounting bracket 6 provide a multi-position adjustment base for the fixed seat 701. The dual fixing mechanism of the positioning bolt 703 and the locking bolt 704, combined with the cooperation of the locking rod 705 and the fastening nut 706, not only ensures the stability of the hook-8 after installation and prevents it from loosening due to vibration during the iron ladle inversion operation, but also realizes the flexible adjustment of the horizontal position of the hook-8, adapting to the suspension requirements of iron ladles of different specifications, expanding the scope of application of the equipment, and improving its applicability.

[0018] Example 2 Based on Example 1, such as Figure 2 and 5As shown, in one embodiment, a fixed frame 5 is fixedly installed on the top of several fixed rods 4. An electric guide rail 9 is fixedly installed on one end of the fixed frame 5. A sliding member 10 is slidably sleeved on the upper part of the electric guide rail 9. A vertical moving mechanism 11 is provided at the bottom of the sliding member 10. The vertical moving mechanism 11 includes an adjusting screw 113, a connecting member 114, and a fixing member 115. The fixing member 115 is fixedly connected to the connecting member 114, and a hook 12 is fixedly installed at the bottom. A motor 112 is fixedly installed on one end of the adjusting screw 113, and can drive the connecting member 114, the fixing member 115, and the hook 12 to move vertically when rotating. The electric guide rail 9 can drive... The sliding member 10 and hook 12 are moved horizontally. The vertical moving mechanism 11 also includes two guide rods 116, both of which are fixedly connected to the top of the connecting member 114. Fixing plates 13 are fixedly installed on both sides of the outer wall of the sliding member 10. The two guide rods 116 are slidably engaged with the two fixing plates 13 respectively. The vertical moving mechanism 11 also includes a fixed housing 117, which is fixedly installed on the outer wall of the sliding member 10. The motor 112 is fixedly installed inside the fixed housing 117 and also fixedly installed on the top of the sliding member 10. The adjusting screw 113 is rotatably connected to the sliding member 10 and threadedly connected to the connecting member 114.

[0019] In this embodiment, the fixed frame 5 and the fixed rod 4 provide stable support for the electric guide rail 9. The cooperation between the electric guide rail 9 and the sliding member 10 enables the flexible horizontal movement of the hook 2 12. In the vertical movement mechanism, the motor 112 drives the adjusting screw 113 to rotate, and the connecting member 114 is moved by the threaded transmission. The sliding cooperation between the guide rod 116 and the fixed plate 13 ensures the smoothness and accuracy of the movement process and avoids the hook 2 12 from deviating when moving vertically. The fixed outer shell 117 protects the motor 112 and enhances the durability of the mechanism. The overall structure allows the hook 2 12 to be precisely adjusted in both horizontal and vertical directions. Together with the hook 1 8, it forms a multi-dimensional adjustable suspension system, which expands the working range and can adapt to the inverting requirements of different molten iron ladles in complex scenarios, improving the flexibility and accuracy of the operation.

[0020] The working principle of this molten iron ladle reversing device will be explained in detail below: The fixing seat 701 of the connecting component 7 is slid into the mounting frame 6 along the inner wall of the mounting frame 6 and fixed to the bottom of the support frame 3. Positioning grooves 601 are equidistantly opened on the inner wall, and locking grooves 602 are opened through the outer wall. According to the spacing of the trunnions of the molten iron ladle, the fixing seat 701 is slid to a preset position so that the hook 8 can accurately align with one of the trunnions of the molten iron ladle. Then, double fixing is performed: the positioning bolt 703 is screwed in, so that it passes through the fixing seat 701 and is threadedly connected to the positioning groove 601 on the inner wall of the mounting frame 6, achieving initial positioning of the fixing seat 701 and preventing horizontal positioning. Slide the bolt and tighten it into the locking bolt 704 so that it passes through the square groove 702 on the outer wall of the fixed seat 701 and is threaded into the locking groove 602 on the outer wall of the mounting bracket 6 to complete the secondary locking and prevent the fixed seat 701 from loosening due to vibration during operation. Finally, install the hook 8. Insert the locking rod 705 horizontally through the reserved hole of the fixed seat 701. After the hook 8 is fitted on the outer wall of the locking rod 705, tighten the fastening nuts 706 at both ends of the locking rod 705 to make the hook 8 tightly fixed to the fixed seat 701 and ensure the load-bearing stability during hanging. Two hooks 1 and 8 are installed and fixed on the mounting frame 6 through the connecting component 7. The hooks 1 and 8 are used to hook the corresponding lifting point of the molten iron ladle and lift it up. After the crane body 1 moves the molten iron ladle to the designated working position through the connecting plate 2 and the bearing frame 3, the electric guide rail 9 and the vertical moving mechanism 11 on the fixed frame 5 are started. The sliding part 10 drives the hook 2 and 12 to move horizontally to the lifting ring behind the molten iron ladle and then moves vertically to adjust the height, ensuring that the hook 2 and 12 accurately hook the lifting ring. Then, while the electric guide rail 9 drives the hook 2 and 12 to move horizontally, the motor 112 of the vertical moving mechanism 11 drives the adjusting screw 113 to rotate, driving the hook 2 and 12 to move vertically. Through the coordinated horizontal and vertical movement of the hook 2 and 12, the molten iron ladle rotates around the lifting point of the hook 1 and 8, realizing the ladle reversal operation and completing the pouring of molten iron.

[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
