Description

Technical Field

[0001] This application relates to the field of metallurgical baking technology, and in particular to a protective device for a slab baking oven cover and a slab baking system. Background Technology

[0002] In modern industrial production, especially in the steel metallurgy sector, slabs are a core piece of equipment. The main function of the tundish heat exchanger is to heat the tundish lining to the required temperature. This helps reduce the temperature drop of molten steel during casting, improving continuous casting efficiency and product quality. The performance of the heat exchanger directly affects the stability and safety of continuous casting production. Traditional heat exchanger raising and lowering operations present several safety hazards. For example, the heat exchanger uses a hydraulic system for lifting and lowering control. The hydraulic transmission system may fail due to internal leakage in hydraulic cylinder components, oil pipe rupture, hydraulic pump failure, or control valve malfunction. Once the hydraulic system fails, the heat exchanger may not be able to raise or lower normally, or may even suddenly fall. After prolonged operation, the heat exchanger may malfunction due to wear of mechanical connections, aging or damage of parts, or breakage of connecting components, which may cause the heat exchanger to lose balance, leading to a safety accident where the heat exchanger lid falls. Furthermore, operators may make mistakes when operating the heat exchanger, such as misoperating control buttons or failing to correctly judge the heat exchanger's position, which may cause the heat exchanger to stop or move in an inappropriate position, increasing the risk of a fall.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0018] like Figure 1 , Figure 2 As shown, Figure 1 This application provides a front view of the protective device under operating conditions for an embodiment of the present application. Figure 2 A side view of the protective device under operating conditions is provided for an embodiment of this application. The protective device for a slab baking oven cover 801 includes a main body, a driving component 300, and a counterweight 400, wherein: like Figure 1 , Figure 2 As shown, the main body includes a base 101 and a stand 102 that are fixedly connected. A rotating component 200 is rotatably provided on the stand 102. A first connecting position and a second connecting position are symmetrically arranged on the rotating component 200 along the central axis. The first connecting position is used to connect the oven cover 801.

[0019] like Figure 3 As shown, Figure 3 A side view of a portion of the counterweight 400 is provided for this embodiment of the application. The base 101 serves as the foundation of the entire protective device, and its fixed connection provides necessary support and stability. The base 101 can withstand high temperatures and heavy loads, ensuring stability during baking. The upright 102 is fixedly connected to the base 101, forming a vertical structure for supporting the rotating component 200. The structure of the upright 102 takes into account strength and durability to accommodate various stresses that may occur during baking.

[0020] The rotating component 200 is mounted on the stand 102 and is capable of rotating along the central axis. This allows the rotating component 200 to rotate during the baking operation, facilitating the lifting and lowering drive of the oven cover 801 and making it easier to operate on the slab at the target position.

[0021] The rotating component 200 has a first connection position and a second connection position symmetrically arranged along its central axis. This symmetrical layout helps maintain the balance and stability of the rotating component 200 during dynamic operation. The first connection position is used to connect the oven cover 801, ensuring that the cover can be firmly fixed in a preset position on the rotating component 200. The connection method of the oven cover 801 can be mechanical, such as bolt connection, or a quick-release mechanism, for easy replacement or maintenance of the oven cover 801. The second connection position provides the connection base for the drive component 300 and the counterweight 400. This allows the drive component 300 and the counterweight 400 to flexibly cooperate with the rotating component 200, and during the operation of the rotating component 200, the first and second connection positions are used evenly to achieve dynamic balance, resulting in better operational performance and reliability.

[0022] like Figure 4 As shown, Figure 4 A side view of a portion of the drive member 300 is provided for an embodiment of this application. The drive member 300 is movably connected between the rotating member 200 and the base 101. The drive member 300 is retractable and is used to drive the rotating member 200 to rotate. One end of the drive member 300 is connected to the second connection position.

[0023] The drive component 300 is movably connected between the rotating component 200 and the base 101. By controlling the extension and retraction of the drive component 300, the rotating component 200 is driven to rotate. This allows the rotating component 200 to be precisely positioned and adjusted as needed.

[0024] like Figure 1 , Figure 2 As shown, the counterweight 400 is movably connected to the second connection position. The function of the counterweight 400 is to increase the dynamic stability of the rotating component 200. Especially in the event that the oven lid 801 falls due to an accident or the drive component 300 fails, the counterweight 400 provides a counterweight balance on the opposite side of the rotating component 200 relative to the oven lid 801, so as to ensure the balance and stability of the rotating component 200 during operation.

[0025] In an optional embodiment, the protective device of this application is applied to the slab baking oven cover 801 and provides reliable protection during the operation of the slab baking oven cover 801. The working principle of the protective device is as follows: the protective device includes a main body, a driving component 300, and a counterweight 400. The main body includes a fixedly connected base 101 and a support frame 102. A rotating component 200 is rotatably mounted on the support frame 102. The rotating component 200 has a first connecting position and a second connecting position symmetrically arranged along its central axis. The first connecting position is used to connect the baking oven cover 801. The driving component 300 is movably connected between the rotating component 200 and the base 101. The driving component 300 is retractable and is used to drive the rotating component 200 to rotate. One end of the driving component 300 is connected to the base 101. On the second connection position; the counterweight 400 is movably connected to the second connection position. During the baking operation, the drive component 300 extends and retracts, causing the rotating component 200 to rotate on the upright 102. The baking oven cover 801, which is arranged on the other side of the rotating component 200 and stably connected, also performs a synchronous lifting operation in the opposite state. It is pre-positioned under the intermediate bag below the baking oven cover 801 by hoisting equipment, and works in conjunction with the baking oven cover 801 which has descended to the target position. During the rotation of the rotating component 200, the counterweight 400 provides counterweight protection to prevent the baking oven cover 801 from falling out of control, thereby improving operational safety and the smoothness of the production process, reducing equipment damage and personnel injury caused by equipment falling, and ensuring the continuous and reliable operation of production.

[0026] like Figure 1 , Figure 2 As shown, in an optional embodiment, the protective device further includes an assembly rod 500 movably connected to the main body, and the counterweight 400 is detachably mounted on the assembly rod 500.

[0027] In some alternative embodiments, the protective device also includes a mounting rod 500 movably connected to the main body. This mounting rod 500 provides flexible connection and positioning on the main body, offering additional adjustment and configuration options.

[0028] The counterweight 400 is detachably mounted on the mounting rod 500. This allows the user to flexibly install the counterweight 400 according to specific operational needs and environmental conditions to adjust the balance and stability of the rotating component 200. The mounting rod 500 may be designed with specific grooves, holes, or other interfaces to facilitate the quick installation and removal of the counterweight 400.

[0029] like Figure 1 , Figure 2As shown, in an optional embodiment, the counterweight 400 includes multiple counterweight units 401. In this embodiment, the counterweight 400 is no longer a single unit, but comprises multiple counterweight units 401. This provides greater flexibility because each counterweight unit 401 can be adjusted or replaced independently.

[0030] The counterweight units 401 can be of the same or different weights to accommodate different balance requirements. This modular design makes the protective device easier to adapt to different operating conditions.

[0031] The counterweight unit 401 can be secured to the mounting rod 500 in various ways, such as using clamps, magnets, bolts, etc. These connections should be both secure and allow for quick disassembly to facilitate adjustment of the counterweight when needed.

[0032] The distribution of the counterweight units 401 can also be adjusted as needed to achieve the best balance. For example, the position of the counterweight units 401 can be adjusted according to the rotational dynamics of the rotating component 200 and the load distribution to reduce vibration or improve stability.

[0033] like Figure 1 , Figure 2 As shown, in an optional embodiment, connecting supports 600 are respectively provided between the rotating component 200 and the oven cover 801, the driving component 300, and the counterweight 400. These connecting supports 600 are respectively arranged at the first connecting position and the second connecting position. The function of these connecting supports 600 is to provide stable connection points, ensuring proper alignment and fixation between the components.

[0034] The connecting supports 600 are made of heat-resistant and high-strength materials, such as stainless steel or special alloys, to withstand high temperatures and heavy loads. The connecting supports 600 are respectively arranged at the first and second connecting positions of the rotating component 200. This helps to distribute the load, reduce stress concentration at individual connection points, and thus improve the durability and reliability of the entire device.

[0035] The connecting support 600 at the first connecting position is used to fix the oven cover 801, while the connecting support 600 at the second connecting position is used to fix the drive component 300 and the counterweight component 400. This allows the rotating component 200 to be flexibly connected and disconnected from these components.

[0036] In an optional embodiment, a plurality of the connecting supports 600 are arranged at axial intervals along the rotating member 200. This arrangement of multiple connecting supports 600 at axial intervals along the rotating member 200 can provide a more uniform load distribution and reduce component damage caused by concentrated loads.

[0037] The spaced-apart connecting supports 600 can be evenly distributed or optimized according to the actual load and stress distribution. This flexibility allows the protective device to better adapt to different working environments and requirements. Because the connecting supports 600 are spaced-apart, each support can be operated individually when maintenance or replacement is required, without affecting other supports. This simplifies maintenance work and reduces maintenance costs.

[0038] The design of the connecting support 600 may also include a quick-release mechanism to facilitate quick replacement or adjustment of the oven cover 801 or the drive unit 300 when needed.

[0039] like Figure 2 , Figure 3 As shown, in an optional embodiment, the protective device further includes a limiting member, which is fixedly mounted on the upright 102.

[0040] The limiting component restricts the movement range of the rotating component 200, preventing excessive rotation or displacement during operation, thereby protecting the safety of the device and operators. The limiting component is fixedly mounted on the upright frame 102, enabling it to form a stable structure with the upright frame 102, jointly bearing the forces generated by the rotating component 200 during operation.

[0041] like Figure 3 , Figure 4 As shown, in an optional embodiment, the limiting member includes a first support 701 fixedly connected to the upright 102, the first support 701 being used to laterally block one side of the upright 102.

[0042] The first support 701 is fixedly connected to the upright frame 102 and is used to laterally block one side of the upright frame 102. When the oven cover 801 falls, the first support 701 blocks one side of the upright frame 102, preventing the oven cover 801 from hitting the upright frame 102 under the traction of the rotating component 200. Thus, the first support 701 and the upright frame 102 together form an impact barrier against the oven cover 801, providing reliable protection for operators and important equipment areas. The first support 701 can be adjusted according to the size and rotation range of the rotating component 200 to achieve the best limiting effect.

[0043] like Figure 3 , Figure 4 As shown, in an optional embodiment, the limiting member further includes a second support 702 fixedly connected to the first support 701, the second support 702 being used to extend to the lower part of the oven cover 801.

[0044] The second support 702 is fixedly connected to the first support 701 and extends to the lower region of the oven cover 801. This helps to limit the movement of the rotating member 200 in the vertical direction through structural interference with the oven cover 801, further enhancing the stability of the device.

[0045] The second support 702 extends to the lower part of the oven cover 801, forming a support and protection for the oven cover 801 to prevent the oven cover 801 from sagging. The second support 702 can be adjusted according to the size and shape of the oven cover 801 to achieve the best limiting effect.

[0046] In an optional embodiment, the base 101 is provided with a hydraulic valve holder 802. The hydraulic valve holder 802 provides a centralized location for installing and securing all hydraulic valves. This integrated management helps simplify the layout of the hydraulic system and improves the efficiency of maintenance and repair. By centrally mounting the hydraulic valves on the valve holder on the base 101, operators can more easily access and operate these valves, thereby improving operational convenience and safety.

[0047] Adding a hydraulic valve platform bracket 802 to the base 101 not only improves the convenience of operation and the stability of the system, but also enhances the efficiency and safety of maintenance.
