Description

Technical Field

[0001] This utility model belongs to the field of molten iron ladle technology, specifically relating to a molten iron ladle that can improve casting safety. Background Technology

[0002] Molten iron ladles are commonly used in metal processing. They serve as containers to store molten iron at high temperatures. Molten iron can be moved using ladles and poured into molds through pouring spouts for metal processing. Existing molten iron ladles need to be quickly moved to the pouring area after high-temperature processing. Due to the limitations of the suspension structure, a ladle moving device is usually required to change the position of the ladle.

[0003] Chinese Patent Publication No. CN218855606U discloses a "Mobile Device Facilitating Stable Transfer of Molten Iron Ladles," which includes a molten iron ladle and a transfer vehicle. The transfer vehicle is equipped with a clamping device for clamping the molten iron ladle, and also with a positioning device that drives the clamping device to clamp the molten iron ladle. The positioning device can hold the molten iron ladle. The positioning device and the clamping device are movably connected to the transfer vehicle. The positioning device can be driven by the gravity of the molten iron ladle to clamp the molten iron ladle. Through the combined use of the positioning device and the clamping device, the position of the molten iron ladle on the transfer vehicle can be locked and positioned, ensuring the stability of the molten iron ladle during transfer, reducing the probability of shaking, and preventing safety hazards. At the same time, the weight of the molten iron ladle directly drives the positioning device and the clamping device to clamp and position, reducing the difficulty of operation.

[0004] In existing technology, the internal limiting structure is retracted by its own weight during use, and the spring will push the clamping mechanism to clamp and restrict the molten iron ladle. However, when the molten iron ladle is removed, the outer clamping structure does not automatically reset, which is inconvenient for operators. Utility Model Content

[0005] The purpose of this utility model is to provide a ladle that improves casting safety, thereby solving the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: It includes a base plate and a pouring barrel disposed on the base plate. Rotating rods are symmetrically arranged on the outer wall of the pouring barrel. Two support columns are provided on the base plate, and the pouring barrel is disposed between the two support columns. The rotating rods are respectively rotatably inserted into the support columns. It also includes a protective device disposed on the base plate. The protective device includes a protective component and an anti-tipping component. The protective component includes three protective plates and a second protective plate fixedly embedded in the protective plates. One of the protective plates is fixedly connected to the base plate. The protective plate is disposed on one side of the support column. The two protective plates are respectively fixedly connected to opposite sides of the protective plate on the base plate, and the protective plates form a predetermined non-zero angle with the support column.

[0006] It should be noted in the solution that the anti-tipping component includes an anti-roll block fixedly mounted on the base plate. The anti-roll block is positioned between two support columns and located on one side of the casting barrel. The side of the anti-roll block facing the casting barrel is arc-shaped, and a T-shaped groove is formed on the arc surface of the anti-roll block. A slider is provided at the bottom of the casting barrel, and the bottom of the slider passes through the T-shaped groove.

[0007] It should be noted in the solution that a bidirectional motor is installed on the side of the protective plate away from the pouring tank. The output end of the bidirectional motor rotates out of the protective plate and is fixedly connected to the rotating rod.

[0008] It should be noted in the solution that the protective plate has two handles on the side away from the pouring tank. The two handles are located in the middle of the protective plate, and each handle is equipped with a control switch, which is electrically connected to the bidirectional motor.

[0009] It should be noted in the plan that the second protective plate is made of transparent material.

[0010] It should be noted in the design that the bottom of the base plate is equipped with several rollers.

[0011] It should be noted in the solution that mounting blocks are fixedly connected to all four corners of the base plate.

[0012] Compared with the prior art, the molten iron ladle provided by this utility model can improve casting safety and has at least the following beneficial effects:

[0013] (1) The entire tilting process is isolated by a protective plate, and the operator can observe the internal situation through the second protective plate, effectively preventing injury caused by accidental splashing of high-temperature molten metal. Reset: After the pouring is completed, the drive mechanism is reversed to slowly reset the pouring barrel, and the slider slides back to the initial position along the T-shaped groove. Through the above implementation method, the device realizes stable and controllable pouring operation under the premise of ensuring safety.

[0014] (2) This embodiment achieves semi-automation by directly mounting the bidirectional motor on the protective plate and connecting it directly to the rotating rod, thus realizing precise and labor-saving automatic pouring. In terms of safety, the motor and the operator are located on opposite sides of the protective plate, physically isolating the driving risk and the pouring risk. In terms of stability, the electromechanical drive combined with the mechanical anti-tipping structure makes the movement more stable and controllable, greatly improving the reliability and safety of the entire system.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A ladle for improving casting safety includes a base plate 1 and a pouring bucket 4 mounted on the base plate 1. Rotating rods 5 are symmetrically arranged on the outer wall of the pouring bucket 4. Two support columns 2 are provided on the base plate 1, and the pouring bucket 4 is positioned between the two support columns 2. The rotating rods 5 rotate and pass into the support columns 2 respectively. The ladle also includes a protective device mounted on the base plate 1. The protective device includes a protective assembly and an anti-tipping assembly. The protective assembly includes three protective plates 6 and a second protective plate 7 fixedly embedded in the protective plates 6. One of the protective plates 6 is fixedly connected to the base plate 1. Plate 6 is disposed on one side of support column 2. Two protective plates 6 are respectively fixedly connected to opposite sides of protective plate 6 on base plate 1. The protective plates 6 form a predetermined non-zero angle with the base plate 2. The anti-tipping assembly includes an anti-roll block 11 fixedly disposed on base plate 1. The anti-roll block 11 is disposed between two support columns 2 and located on one side of casting barrel 4. The side of anti-roll block 11 facing casting barrel 4 is arc-shaped. A T-shaped groove 13 is provided on the arc surface of anti-roll block 11. A slider 14 is provided at the bottom of casting barrel 4. The bottom of slider 14 passes into the T-shaped groove 13.

[0022] By incorporating protective and anti-tipping components, the core of this equipment lies in restricting personnel from getting too close to the rotating casting tank through the protective components and preventing the casting tank from slipping or tipping over during tilting, thus ensuring operational safety. Before assembly, the following main components should be prepared: Base plate 1: serving as the foundation platform for the entire equipment; Support columns 2: two, fixedly installed on the base plate to support the rotating rod; Casting tank 4: a container for holding and pouring molten metal; Rotating rod 5: symmetrically fixed to the outer wall of the casting tank as the rotation axis; Protective components: including three protective plates 6 and a second protective plate 7 (usually made of transparent materials such as high-temperature resistant glass for observation) fixedly embedded within them; Anti-tipping components: including an anti-roll block 11, one side of which is arc-shaped and has a T-shaped groove 13, and a slider 14 fixed to the bottom of the casting tank.

[0023] Installation and Implementation Steps

[0024] Step 1: Install the foundation structure and pouring bucket. Fix the two support columns 2 in the predetermined positions on the base plate 1, ensuring that they are parallel and the spacing is accurate. Hoist the pouring bucket 4 between the two support columns 2. Align the rotating rod 5 with the bearing hole on the support column 2. Slowly move the pouring bucket so that the rotating rod 5 passes into the support column, thereby realizing that the pouring bucket 4 can be rotatably erected between the two support columns 2.

[0025] Step 2: Install the protective components. First, fix one of the protective plates 6 (main protective plates) onto the base plate 1. Its position should be on one side of the support column 2, i.e., the side where the operator usually stands, maintaining a safe distance from the pouring tank 4. Then, fix the other two protective plates 6 onto the base plate 1 respectively. They are connected to the main protective plate installed in the first step and form a predetermined non-zero angle (e.g., 90° or 120°, together forming a semi-enclosed or larger protective area). These three protective plates together isolate the operating area of ​​the support column and the pouring tank, ensuring that all the second protective plates 7 (observation windows) are firmly embedded in the corresponding protective plates 6 in advance, and the position is conducive to observing the tilting state of the pouring tank and the liquid level inside the tank.

[0026] Step 3: Install the anti-tipping assembly. Securely install the anti-roll block 11 onto the base plate 1. Its installation position must be between the two support columns 2 and adjacent to the bottom of the casting tank 4 (usually the side opposite the protective plate). During installation, ensure the curved surface of the anti-roll block 11 faces the body of the casting tank 4. Install the slider 14 at the bottom of the casting tank 4. The position of the slider 14 should correspond to the trajectory of the T-shaped groove 13 on the anti-roll block 11. By slightly rotating the casting tank 4, adjust the position of the bottom slider 14 so that its bottom can smoothly enter the T-shaped groove 13. Since the groove is T-shaped, the slider 14 is also designed with a matching T-shaped head, thus forming a sliding fit, allowing it to move only along the length of the groove without dislodging.

[0027] Operating Procedures: Initial State: The pouring tank 4 is in an upright position, with the slider 14 located at one end of the T-shaped groove 13. Pouring Operation: The pouring tank 4 is tilted and poured by rotating around the rotating rod 5 via an external drive mechanism. Anti-tipping Process: During the tilting process of the pouring tank 4, the slider 14 at its bottom slides along the T-shaped groove 13 of the anti-roll block 11. Anti-forward and backward slippage: The two side walls of the T-shaped groove effectively limit the left and right swaying of the slider, preventing the pouring tank from slipping off the support column due to the shift in the center of gravity. Anti-radial rolling: The arc-shaped surface of the anti-roll block 11 is in close contact with the outer wall of the bottom of the pouring tank 4, acting like a "brake" to provide radial support for the tilting of the pouring tank, preventing it from tilting too quickly or tipping forward due to inertia or loss of control. Protection: The entire tilting process is isolated by a protective plate, and the operator can observe the internal situation through the second protective plate 7, effectively preventing injury caused by accidental splashing of high-temperature molten metal. Reset: After pouring is completed, the reverse operation of the drive mechanism is used to slowly reset the pouring barrel 4, and the slider 14 slides back to the initial position along the T-shaped groove 13. Through the above implementation method, the device realizes stable and controllable pouring operation under the premise of ensuring safety.

[0028] Furthermore, referring to Figure 1-4 As shown, it is worth noting that a bidirectional motor 8 is installed on the side of the protective plate 6 away from the pouring tank 4. The output end of the bidirectional motor 8 rotates through the protective plate 6 and is fixedly connected to the rotating rod 5. Two handles 10 are provided on the side of the protective plate 6 away from the pouring tank 4. The two handles 10 are located in the middle of the protective plate 6. Each handle 10 is provided with a control switch, and the control switch is electrically connected to the bidirectional motor.

[0029] By installing the bidirectional motor 8 on the outer side of the main protective plate 6 away from the pouring tank 4, the bidirectional motor 8 is securely fixed to its base using high-strength bolts, ensuring that the motor shaft and the axis of the rotating rod 5 are aligned. A coupling (not shown in the figure, but a necessary component) is used to securely connect the output end of the bidirectional motor 8 to the rotating rod 5. After installation, the motor needs to be manually rotated to check whether the connection is smooth and whether there is any jamming. The bidirectional motor 8 is connected to the motor controller via a power cable. The control switch and emergency stop button are installed in a convenient location with good visibility (such as the outer side of the protective plate) and connected to the motor controller via control cables. This embodiment achieves semi-automation by directly installing the bidirectional motor 8 on the protective plate and directly connecting it to the rotating rod: achieving precise and labor-saving automatic pouring; safety: the motor and operator are located on opposite sides of the protective plate, physically isolating the driving risk and the pouring risk; stability: the electromechanical drive combined with the mechanical anti-tipping structure makes the movement more stable and controllable, greatly improving the reliability and safety of the entire system.

[0030] Furthermore, referring to Figure 1-4As shown, it is worth noting that the second protective plate 7 is made of transparent material, the bottom of the base plate 1 is provided with several rollers, and the four corners of the base plate 1 are all fixedly connected with mounting blocks 15;

[0031] Through the installation and integration steps of the feed pipe 9, the operating path of the casting equipment is planned on the workshop floor. This path should connect the smelting furnace, mold line, and other workstations. The track is precisely laid along the planned path to ensure that the track is flat, level, and firmly fixed to the foundation. The track spacing is strictly matched with the wheel spacing of the rollers at the bottom of the base plate 1.

[0032] Operating procedures: First, unlock: Release the equipment's braking system (rollers are usually equipped with a locking mechanism). Lifting and connection: Operate the workshop gantry frame, ensuring its lifting device engages and securely connects with the mounting blocks 15 at the four corners of the base plate. Traction and movement: Using the power provided by the gantry frame, traction is used to move the entire equipment along the ground track. The rollers roll within the track, ensuring precise and smooth movement. Precise positioning: Accurately move the equipment to the target workstation (e.g., below the molten metal outlet of the smelting furnace or above the mold pouring port). Fixing: Activate the roller braking mechanism to securely lock the equipment in its current position, preventing movement during pouring. Observation and control: The operator can clearly observe the pouring process through the transparent protective plate 7 and control the tilting speed or stop as needed.

[0033] This implementation method achieves the following advantages through systematic integration: Safety and Automation: The bidirectional motor drive enables unmanned automatic tilting, completely isolating operators from high-temperature and high-risk areas; the transparent protective plate provides physical protection while ensuring optimal visibility; Mobility and Precision: The "roller-track" system ensures that the equipment can move efficiently and effortlessly along a fixed path within the workshop; The cooperation between the mounting block and the gantry frame enables rapid hoisting and precise positioning, greatly improving production flow efficiency; Modular Design: Each functional module is clearly defined, facilitating installation, maintenance, and repair. This equipment constitutes a complete, efficient, and safe modern casting solution.
