Description

Technical Field

[0001] This utility model relates to the field of steel ladle accessories technology, and in particular to a vertical lifting steel ladle cover device. Background Technology

[0002] In the steel smelting process, the ladle is an important container for transportation and storage, and maintaining the temperature of the molten steel inside is crucial. However, during the transportation and waiting of the ladle, the temperature of the molten steel will drop rapidly due to the lack of effective heat preservation measures. This not only increases energy consumption, but may also affect the stability of subsequent steelmaking processes and product quality. Currently, although there are some ladle covering devices on the market, most of them have problems such as complex structure, inconvenient operation, and low covering efficiency, which cannot meet the high efficiency and energy-saving requirements of modern steel production. To address this issue, a vertical lifting ladle capping device is proposed to solve the problems mentioned above. Utility Model Content

This vertical lifting ladle cover-adding device adopts a modular design, with simple structure of each component, easy to manufacture and install, reducing the manufacturing cost and maintenance difficulty of the equipment. The vertical lifting of the ladle cover is achieved by driving the hydraulic rod through the hydraulic pump station. The operation is simple and convenient. The covering and uncovering actions can be completed by simply controlling the switch of the hydraulic pump station, which greatly improves work efficiency. 2. The hoisting device uses triangularly arranged lifting rings, which can quickly and accurately connect with the ladle cover, enabling rapid hoisting and placement of the ladle cover and improving the efficiency of covering. The ladle cover and the ladle body are connected by a hinge, which can fit tightly and effectively reduce the temperature loss of molten steel during transportation and waiting, reduce energy consumption, and improve energy utilization efficiency.

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0012] The present invention will be further described below with reference to the accompanying drawings. like Figures 1 to 3As shown, a vertical lifting ladle cover device includes a ladle transport vehicle 1 and a ladle body 2. The ladle transport vehicle 1, as a transport tool for the ladle body 2, is responsible for transporting the ladle body 2 from one process position to another process position. The ladle body 2 is placed on the ladle transport vehicle 1, which is used for transporting the ladle body 2. It also includes support columns 4 and a ladle cover 3. There are two sets of support columns 4, each set having three support columns 4. The support columns 4 in each set are arranged in parallel. The ladle transport vehicle 1 is placed between the two sets of support columns 4. Each set of support columns 4 is vertically erected. The top of the support column 4 is provided with a crossbeam 5, which has four beams and is fixed to the top of the support column 4. The upper end of the crossbeam 5 is provided with a mounting platform 6. A cover device is provided above the mounting platform 6, and the ladle cover 3 is installed on the cover device. The cover device is used to place the ladle cover 3 on the ladle body 2.

[0013] The upper surface of the crossbeam 5 is provided with a mounting platform 6. The cover device is installed on the upper surface of the mounting platform 6. The cover device includes a hydraulic pump station 7, a hydraulic rod 9, a support frame, and a hoisting device. The hydraulic pump station 7 is installed on the mounting platform 6, and the support frame is fixed at the center of the mounting platform 6. The center of the mounting platform 6 is provided with space for the hoisting device to move up and down. The hydraulic pump station 7 is composed of a motor, a hydraulic pump, an oil tank, a control valve, and other components. The motor drives the hydraulic pump to rotate, drawing in and pressurizing the hydraulic oil in the oil tank. Then, the high-pressure hydraulic oil is delivered to the cylinder of the hydraulic rod 9 through the control valve, pushing the piston to move, thereby realizing the extension and retraction of the hydraulic rod 9. The movement speed and direction of the hydraulic rod 9 can be controlled by opening and closing and adjusting the control valve.

[0014] The support frame includes four vertically erected columns 8, which are connected and fixed by connecting rods 81. There are two hydraulic rods 9, which are symmetrically arranged on the two connecting rods 81. The hoisting device is fixed to the output end of the hydraulic rods 9.

[0015] The hoisting device includes a connecting frame 91 and lifting rings 92. There are three lifting rings 92, which are fixed on the connecting frame 91. The connecting frame 91 consists of four steel pipes connected end to end, forming a rectangular frame. This structure gives the hoisting device good stability and load-bearing capacity.

[0016] The lifting rings 92 are arranged in a triangular pattern. This arrangement ensures that the steel ladle cover 3 is subjected to uniform force during hoisting, thereby improving the safety and stability of the hoisting. The steel ladle cover 3 is provided with corresponding hinge seats 32.

[0017] The ladle body 2 is provided with a ladle hinge shaft 21, and the edge of the ladle cover 3 is provided with a ladle cover hook 31. When the ladle cover 3 is closed on the ladle body 2, the ladle cover hook 31 is hinged to the ladle hinge shaft 21. This connection method not only ensures that the ladle cover 3 and the ladle body 2 fit tightly, but also prevents the ladle cover 3 from shaking or falling off during ladle transportation, thus improving the safety and reliability of the equipment.

[0018] The working principle of this utility model is as follows: When in use, after the ladle receives molten steel, it goes to the ladle covering device to prepare for covering. When the ladle car arrives at the ladle covering device, the position of the ladle car is manually adjusted. The opening of the hook of the ladle cover 3 is aligned with the ladle hinge shaft 21. There is an error space of about 150mm here. As long as the ladle hinge shaft 21 is within the space of the opening of the hook of the ladle cover 3, the ladle cover 3 can be lowered to cover. The relevant error will be compensated here. The ladle cover device hook descends, ladle cover 3 covers the ladle, the hook continues to descend, the hook separates from ladle cover 3, the ladle car leaves the ladle cover position and goes to the overhead crane hook position to carry out the next refining or continuous casting process. After the refining or continuous casting process is completed, it returns to continue receiving molten steel. Upon reaching the ladle cover position, the ladle car and hook are manually adjusted. Once the lifting seat on the ladle cover 3 enters the hook, the cover can be lifted. There is approximately 300mm of space at this point. The ladle cover lifting device hook rises and lifts the cover, the ladle cover 3 detaches from the ladle, and the ladle car proceeds to the converter station to receive molten steel.

[0019] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
