[0002] Various hoisting operations occur within the steelmaking area. The process of overhauling the ladle car motor requires lifting the ladle car cover. Initially, the only tool used for hoisting the ladle car cover was a single wire rope sling. The cover was hooked diagonally and then lifted by a crane. However, due to prolonged use, the ladle car cover is prone to slag accumulation during the steel tapping process, causing a shift in the center of gravity and making it susceptible to tilting during hoisting, thus posing a safety hazard.

[0003] In view of this, the existing technology should be improved in order to solve the aforementioned technical problems. Utility Model Content

[0004] The main objective of this invention is to provide a lifting device for ladle car covers and its storage mechanism. It optimizes and transforms existing single-wire rope lifting devices into lifting devices with multiple ropes. During lifting, the ropes maintain consistent length, preventing tipping due to a shift in the center of gravity. This also avoids tipping problems caused by slag accumulation or inconsistent rope lengths on the ladle car cover, significantly reducing safety hazards during such lifting operations.

[0005] According to one aspect of this utility model, a ladle car cover lifting device is provided, comprising:

[0006] Top collar, designed for connection to hoisting equipment;

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] like Figure 1 As shown, this utility model provides a lifting device for a ladle car cover plate 5, which includes a top collar 3, which is configured to be connected to a lifting device; at least three lifting ropes, each of which has a connecting ring and a tail collar 4 at both ends; the top collar 3 passes through the connecting ring of each lifting rope, and the connecting ring of each lifting rope is slidable relative to the top collar 3; the tail collar 4 is configured to be connected to the connecting structure of the ladle car cover plate 5.

[0029] Specifically, the connection between the hoisting equipment and the top collar 3 is the crane hook 2.

[0030] In the ladle car cover lifting device according to the embodiment of the present utility model, the existing single wire rope 1 lifting device is optimized and transformed into a lifting device with multiple lifting ropes. During the lifting process, the length of multiple lifting ropes is kept consistent, and the overturning will not be caused by the shift of the center of gravity. This avoids the overturning problem caused by slag accumulation on the ladle car cover 5 or inconsistent lengths, and greatly reduces the safety hazards in such lifting operations.

[0031] In some embodiments, the suspension rope is a steel wire rope 1 to ensure the stability of the connection.

[0032] In one specific embodiment, the end loop 4 of each hoisting rope is also provided with a D-type shackle, and the open side of the D-type shackle is provided with an anti-detachment bolt. The detachable D-type shackle structure simplifies the installation and disassembly process, facilitates quick replacement or maintenance of hook components, and the anti-detachment bolt design effectively prevents the shackle from accidentally loosening during vibration or load changes, avoiding equipment damage or safety hazards caused by connection failure, and ensuring production continuity.

[0033] When the connecting mechanism of the steel ladle car cover plate 5 is the cover plate hook 6, the cover plate hook 6 is directly hooked onto the tail end collar 4; when it is not hooked, that is, when there is no attachment point on the cover plate, the cover plate and the tail end collar 4 are connected by a D-type shackle.

[0034] Based on the above embodiments, the number of lifting ropes is four. The four ropes, symmetrically distributed, form a multi-point synergistic force-bearing structure, effectively dispersing load stress and avoiding the risk of breakage due to localized overload of a single or few ropes, significantly improving system safety and impact resistance. The four ropes are evenly distributed around the steel ladle car cover plate 5; this geometric symmetry optimizes the load transfer path, reduces sway and vibration during equipment operation, and enhances the accuracy and stability of the lifting or traction process.

[0035] Based on the above embodiments, the top collar 3 is formed by connecting ropes end to end, with each suspension rope and the rope forming the top collar 3 having a diameter ≥16mm. The large diameter design of the suspension rope significantly improves its tensile strength and shear resistance, ensuring stable stress resistance under heavy loads, frequent start-stop operations, or sudden impacts, reducing the risk of breakage due to localized stress concentration, and ensuring operational safety. Furthermore, the increased diameter of the top collar 3 optimizes its compatibility with the suspension rope, dispersing load pressure by increasing the contact area, reducing wear and deformation at the connection between the suspension rope and the top collar 3, and extending the service life of both.

[0036] In one specific embodiment, the top collar 3 is formed by connecting ropes end to end, with each lifting rope and the rope forming the top collar 3 having a length of 2.5 to 3 meters. This length range balances space utilization efficiency and operational flexibility, avoiding the risk of entanglement or spatial interference due to excessive length, while preventing excessive installation tension or overstretching under dynamic loads due to excessive length. This ensures that the lifting ropes maintain an appropriate margin during hoisting or traction to buffer impact loads and reduce stress concentration and fatigue damage. Preferably, the length of the lifting ropes and the top collar 3 is 3 meters.

[0037] In one specific embodiment, the inner wall of the tail collar 4 is provided with anti-slip texture. The anti-slip texture increases the friction coefficient of the contact surface, effectively suppressing the phenomenon of accidental slippage or loosening between the collar and the cover plate hook 6 caused by ladle car vibration, load fluctuation or thermal expansion, ensuring connection stability and reducing the risk of stress concentration caused by displacement.

[0038] In one specific embodiment, the top loop 3 includes a rope and a first buckle connecting the first and second ends of the rope. The connecting loop is formed by folding back one end of the suspension rope and securing it with a second buckle; the tail loop 4 is formed by folding back the other end of the suspension rope and securing it with a third buckle.

[0039] The first locking design simplifies the connection process between the lifting device and the ladle car cover, eliminating the need for complex knotting or welding. After the first and last ends are closed, the load is evenly distributed across the entire collar, avoiding stress concentration at a single point.

[0040] The second locking mechanism forms a closed loop after closing, preventing accidental disengagement during hoisting.

[0041] The third latch can be adjusted to quickly match loads of different shapes or weights.

[0042] In one specific embodiment, each hoisting rope is equipped with a length adjustment mechanism in the middle section, which includes a spiral buckle located in the middle section of the wire rope 1. The spiral buckle structure allows for precise fine-tuning of the length of the wire rope 1, ensuring uniform tension distribution of each rope during hoisting, avoiding uneven loading or local overload caused by length deviation, reducing the risk of abnormal wear and breakage of the wire rope 1, and adapting to different specifications of ladle car cover plates 5 or working space requirements, thus enhancing the equipment's versatility.

[0043] This application also proposes a storage device for a ladle car cover lifting device, which includes a storage bracket for storing the ladle car cover 5 lifting device. The storage bracket includes a positioning groove that matches the shape of the ladle car cover 5 lifting device, and the bottom of the storage bracket is equipped with self-locking casters. The positioning groove precisely matches the shape of the lifting device, ensuring a stable fit during storage and preventing the lifting device from sliding, tipping, or being damaged by collision. It also reduces the time required for manual alignment and improves storage efficiency. The self-locking casters at the bottom allow the bracket to be flexibly moved to a designated position and then locked with a single button, facilitating quick adjustments to the layout according to operational needs.

[0044] A specific application of this utility model is as follows: to check whether the ladle car cover plate lifting device is in good condition. After the inspection is completed, the top collar 3 is vertically hung into the crane hook 2, and the bottom tail collar 4 is hung into the cover plate hook 6. The wire rope 1 is kept under uniform force. If the ladle car cover plate 5 is a seamless structure, D-type shackles are installed in advance and the tail collar 4 is connected to the ladle car cover plate 5 through the D-type shackles.

[0045] This utility model has the following advantages: it optimizes and transforms the existing single wire rope lifting device into a lifting device with multiple lifting ropes, ensuring that the lengths of the multiple lifting ropes are consistent during the lifting process, preventing tipping due to center of gravity shift, and avoiding tipping problems caused by slag accumulation or inconsistent lengths on the ladle car cover plate 5, thus greatly reducing safety hazards in such lifting operations; since there are different types of ladle car cover plates 5, the tail end collar 4 of the lifting device can meet the usage requirements under different conditions.

[0046] Those skilled in the art should understand that, in the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
