Description

Technical Field

[0001] This application relates to the field of hot rolling production line technology, and in particular to a protective plate assembly and production system for hot rolling laminar flow cooling. Background Technology

[0002] In hot rolling production lines of the steel metallurgical industry, pneumatic butterfly valves are key control equipment. Their routine maintenance and adjustment often require workers to operate them at heights or on uneven work surfaces. Currently, to ensure operational safety, the industry commonly uses movable safety pedals as temporary support devices. Before adjusting the pneumatic butterfly valve, workers must move the pedal to the appropriate location for installation, providing a foothold. However, existing movable safety pedals have significant drawbacks in practical applications. Due to their weight, workers must traverse smooth, slippery areas of the cold-rolling conveyor during transport, making them highly susceptible to slipping and falling due to wet or uneven surfaces. This poses a serious safety hazard, reducing work efficiency, increasing worker workload and safety risks, and failing to provide reliable support, severely threatening the safety of working at heights. These shortcomings not only affect equipment maintenance efficiency but also pose a significant threat to the personal safety of workers. Summary of the Invention

[0003] In view of the deficiencies in the prior art, this application provides a hot-rolled laminar flow cooling guard plate assembly and production system to solve the problem of poor reliability of temporary pedals in the prior art.

[0004] The above-mentioned objectives of this application are mainly achieved through the following technical solutions: A hot-rolled laminar flow cooling guard plate assembly, the guard plate assembly comprising: The vertical plate assembly is located at the lower part of the pneumatic butterfly valve in a vertical direction; A horizontal plate assembly is fixedly mounted on the vertical plate assembly in a horizontal direction, and the horizontal plate assembly has a working surface for stepping on; A connecting assembly is fixedly connected to the vertical plate assembly, and the connecting assembly is used for detachable connection to one side of the laminar flow roller.

[0005] In an optional embodiment, the upright plate assembly is vertically connected to the horizontal plate assembly, and a support member is provided between the upright plate assembly and the horizontal plate assembly.

[0006] In an optional embodiment, the support member includes a plurality of spaced-apart support plates, which are fixedly connected to the vertical plate assembly and the horizontal plate assembly.

[0007] In an optional embodiment, the cross plate assembly is provided with an anti-slip portion.

[0008] In an optional embodiment, the anti-slip part includes a first protrusion and a second protrusion. The first protrusion is fixedly disposed on the edge of the working surface, and multiple second protrusions are provided and disposed parallel to each other on the working surface.

[0009] In an optional embodiment, the thickness of the first convex strip and the second convex strip is 10mm-15mm.

[0010] In an optional implementation, the width of the working surface is not less than 20cm.

[0011] In an optional embodiment, the connecting assembly includes a first connecting plate and a second connecting plate that are vertically connected, with the first connecting plate fixedly connected to the upright plate assembly.

[0012] In an optional embodiment, the first connecting plate and / or the second connecting plate are fixedly connected to the base on one side of the laminar flow roller by bolts.

[0013] Based on the same inventive concept, this application also provides a hot-rolled laminar flow cooling production system, the production system including the guard plate assembly as described above.

[0014] Compared with the prior art, the advantages of this application are: The guard plate assembly in this application is used in hot rolling laminar flow cooling operations. The guard plate assembly includes a vertical plate assembly, a horizontal plate assembly, and a connecting assembly. The vertical plate assembly is disposed vertically below the pneumatic butterfly valve. The horizontal plate assembly is fixedly disposed horizontally on the vertical plate assembly and has a working surface for stepping on. The connecting assembly is fixedly connected to the vertical plate assembly and is detachably connected to one side of the laminar flow cooling roller table.

[0015] This guard plate assembly combines vertical plate components, horizontal plate components, and connecting components. The connecting components are detachably fixed to one side of the laminar flow roller conveyor, eliminating the need for operators to manually carry heavy objects across the slippery roller conveyor surface and preventing the risk of slipping while carrying heavy loads on smooth rollers. Furthermore, because the guard plate assembly is directly installed on the side of the laminar flow roller conveyor, operators only need to perform installation and removal operations at a fixed location, without repeatedly traversing hazardous areas, significantly improving operational safety.

[0016] The vertical plate assembly is positioned vertically below the pneumatic butterfly valve, while the horizontal plate assembly is horizontally fixed to the vertical plate assembly, forming a rigid support frame structure. This avoids the assembly gap problems caused by the connection of multiple parts in traditional detachable pedals, ensuring that the entire device does not wobble or become unstable during use. When an operator steps on the working surface of the horizontal plate assembly, the force transmission path is clear: from the horizontal plate assembly through the vertical plate assembly to the connecting assembly, and finally, the connecting assembly firmly supports the side of the laminar flow roller, forming a stable mechanical support system that provides a reliable point of leverage for the operator.

[0017] During operation, workers simply need to fix the connecting assembly in the appropriate position on the side of the laminar flow roller table, and the entire guard plate assembly is ready for use. When multiple adjacent pneumatic butterfly valves need adjustment, because the guard plate assembly is fixedly installed on the side of the roller table, workers can cover multiple work points by adjusting their standing position without reinstalling the device. This reduces the cumbersome process of repeatedly disassembling, moving, and reinstalling traditional pedals. This not only improves work efficiency but also reduces the labor intensity of workers. Furthermore, by reducing the number of times the equipment needs to be moved, it further reduces safety risks, providing a more reliable guarantee for equipment maintenance operations in the hot rolling production environment.

Detailed Implementation

[0020] 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 invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0021] like Figure 1 , Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the protective plate assembly after installation, as provided in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of the guard plate assembly provided in the embodiments of this application; a hot-rolled laminar flow cooling guard plate assembly, the guard plate assembly including a vertical plate assembly 100, a horizontal plate assembly 200, and a connecting assembly 300, wherein: The vertical plate assembly 100 is vertically positioned below the pneumatic butterfly valve 601. The vertical plate assembly 100 can be integrally formed from high-strength steel plate and is stably positioned vertically in the lower area of ​​the pneumatic butterfly valve 601. This ensures that the horizontal plate assembly 200 reaches a suitable working height for personnel and avoids interference with the moving parts of the cooling roller conveyor 602. A suitable safe distance is maintained between the vertical plate assembly 100 and the pneumatic butterfly valve 601, facilitating observation of the valve's status by operators and preventing direct impact of high-temperature environments on the device. The bottom of the vertical plate assembly 100 and the connecting assembly 300 can be welded together with reinforcing ribs to form a stable triangular support structure. This effectively disperses the vertical load and horizontal thrust generated when operators step on it, ensuring the structural stability of the entire device during use.

[0022] like Figure 1 , Figure 2 As shown, the horizontal plate assembly 200 is fixedly mounted on the vertical plate assembly 100 in the horizontal direction, and the horizontal plate assembly 200 has a working surface for stepping on. The horizontal plate assembly 200 can be made of steel plate and is fixedly connected to the upper end of the vertical plate assembly 100 along the horizontal direction through a full welding process, forming a sturdy overall frame. This completely eliminates the connection gaps present in traditional detachable structures, fundamentally solving the technical problem of unstable device swaying and providing workers with a stable support experience similar to a fixed platform. The working surface of the horizontal plate assembly 200 can be specially treated with raised anti-slip textures, providing sufficient friction for the soles of workers' shoes even in high-temperature, humid, or oily environments to prevent slipping.

[0023] like Figure 1 , Figure 2 As shown, the connecting component 300 is fixedly connected to the vertical plate assembly 100, and the connecting component 300 is used to be detachably connected to one side of the cold roller conveyor 602.

[0024] The detachable arrangement of the connecting assembly 300 allows the guard plate assembly to be quickly transferred between different work points. Since the connecting assembly 300 is directly fixed to the side of the laminar flow roller conveyor 602, operators do not need to manually handle the slippery roller surface, completely avoiding the safety risks associated with traditional handling methods. When maintenance is required on multiple adjacent pneumatic butterfly valves 601, operators only need to slide the guard plate assembly along the side of the roller conveyor to a new position and then re-lock it, greatly improving work efficiency and reducing labor intensity.

[0025] like Figure 1 , Figure 2 As shown, when an operator stands on the working surface of the horizontal plate assembly 200 to adjust the pneumatic butterfly valve 601, their body weight is evenly distributed on the anti-slip working surface through their feet. The load is transferred through the horizontal plate assembly 200 to the vertical plate assembly 100, and finally by the connecting assembly 300 to the fixed structure of the laminar flow roller conveyor 602, forming a complete force transmission path. This ensures the stability of the device and eliminates the shaking phenomenon of traditional pedals through the rigid connection between the components, providing ideal working conditions for precise valve adjustment. The overall structure of the guard plate assembly has undergone finite element analysis and actual working condition testing, and can withstand loads several times greater than those of a single person, ensuring safety and reliability under various extreme working conditions. This solves the technical problems existing in the prior art, such as safety hazards during handling, unstable device shaking, and low efficiency due to repeated disassembly and assembly.

[0026] In an optional embodiment, the guard plate assembly of this application is used in hot rolling laminar flow cooling operations. The guard plate assembly includes a vertical plate assembly 100, a horizontal plate assembly 200, and a connecting assembly 300. The vertical plate assembly 100 is disposed vertically below the pneumatic butterfly valve 601. The horizontal plate assembly 200 is fixedly disposed horizontally on the vertical plate assembly 100 and has a working surface for stepping on. The connecting assembly 300 is fixedly connected to the vertical plate assembly 100 and is detachably connected to one side of the laminar flow cooling roller table 602.

[0027] like Figure 1 , Figure 2 As shown, the guard plate assembly is composed of a vertical plate assembly 100, a horizontal plate assembly 200, and a connecting assembly 300. The connecting assembly 300 is detachably fixed to one side of the laminar flow cooling roller conveyor 602, eliminating the need for operators to manually carry heavy objects across the slippery roller conveyor surface and avoiding the risk of slipping while walking on a smooth roller conveyor. Furthermore, since the guard plate assembly is directly installed on the side of the laminar flow cooling roller conveyor 602, operators only need to perform installation and removal operations at a fixed location, eliminating the need to repeatedly traverse hazardous areas and significantly improving operational safety.

[0028] The vertical plate assembly 100 is vertically positioned below the pneumatic butterfly valve 601, and the horizontal plate assembly 200 is horizontally fixed to the vertical plate assembly 100, forming a rigid support frame structure. This avoids the assembly gap problem caused by the connection of multiple parts in traditional detachable pedals, ensuring that the entire device will not wobble or become unstable during use. When an operator steps on the working surface of the horizontal plate assembly 200, the force transmission path is clear: from the horizontal plate assembly 200 through the vertical plate assembly 100 to the connecting assembly 300, and finally, the connecting assembly 300 firmly supports the side of the cooling roller conveyor 602, forming a stable mechanical support system and providing a reliable point of leverage for the operator.

[0029] like Figure 1 , Figure 2 As shown, during operation, the operator only needs to fix the connecting component 300 to a suitable position on the side of the laminar flow roller 602, and the entire guard plate assembly can be put into use. When it is necessary to adjust multiple adjacent pneumatic butterfly valves 601, since the guard plate assembly is fixedly installed on the side of the roller conveyor, the operator can cover multiple work points by adjusting their standing position without reinstalling the device, reducing the cumbersome process of repeatedly disassembling, moving, and reinstalling the traditional pedal. This not only improves work efficiency but also reduces the labor intensity of the operator, and further reduces safety risks by reducing the number of times the equipment is moved, providing a more reliable guarantee for equipment maintenance operations in the hot rolling production environment.

[0030] like Figure 1 , Figure 2 As shown, in an optional embodiment, the upright plate assembly 100 is vertically connected to the horizontal plate assembly 200, and a support member 401 is provided between the upright plate assembly 100 and the horizontal plate assembly 200.

[0031] The vertical plate assembly 100 and the horizontal plate assembly 200 are perpendicularly connected to each other. In the hot rolling production environment, when workers step on them, they generate a downward vertical load and a horizontal thrust. The vertical connection can most effectively transfer the load along a straight path, avoiding stress concentration and structural deformation caused by angular deviation. The support member 401 further enhances the overall stability by forming a rigid connection node between the vertical plate and the horizontal plate through the principle of triangular stability. When workers move or apply force on the horizontal plate, the support member 401 can effectively resist the bending deformation tendency of the horizontal plate assembly 200, prevent the connection from loosening due to long-term use, and ensure that the entire guard plate assembly remains stable and reliable under harsh working conditions such as high temperature and vibration, fundamentally solving the shaking problem caused by the connection gap of traditional pedals.

[0032] like Figure 1 , Figure 2As shown, in an optional embodiment, the support member 401 includes a plurality of spaced support plates, which are fixedly connected to the vertical plate assembly 100 and the horizontal plate assembly 200.

[0033] Support component 401 employs multiple spaced support plates, reflecting an optimized load distribution arrangement. These support plates are arranged according to the stress conditions of the horizontal plate assembly 200. The density of support plates is appropriately increased in areas frequently stepped on, and appropriately reduced in edge areas, ensuring the strength of critical components while avoiding material waste. Each support plate can be fully welded to the vertical plate assembly 100 and the horizontal plate assembly 200, forming a robust rigid node, making multiple components a unified load-bearing system. In actual use, when a worker steps on the edge of the horizontal plate with one foot, the load can be quickly transferred to the vertical plate assembly 100 through the nearest support plate, avoiding the overall swaying caused by localized stress in traditional pedals. The spaced arrangement of multiple support plates also forms a natural drainage channel, quickly draining accumulated water in wet environments and preventing the risk of slipping due to water accumulation on the work surface.

[0034] like Figure 1 , Figure 2 As shown, in an optional embodiment, the horizontal plate assembly 200 is provided with anti-slip parts. In the laminar flow cooling environment of hot rolling, high-temperature steam, cooling water, and possible oil stains can make the working surface slippery, and traditional flat treads are prone to slipping accidents in such environments. The presence of anti-slip parts provides workers with double safety protection even when wearing anti-slip shoes, greatly reducing the risk of falls from heights due to foot slippage. Adapting to the special environment of hot rolling production, it maintains a durable anti-slip effect under complex working conditions such as high temperature, high humidity, and oil stains, demonstrating a high degree of responsibility for worker safety.

[0035] like Figure 1 , Figure 2 As shown, in an optional embodiment, the anti-slip part includes a first protrusion 501 and a second protrusion 502. The first protrusion 501 is fixedly disposed on the edge of the working surface, and multiple second protrusions 502 are provided and disposed parallel to the working surface.

[0036] The first raised strip 501 is located at the edge of the working surface. While providing anti-slip properties, the first raised strip 501 also serves as a reminder of the edge position for the worker's feet, preventing accidental slippage. The multiple parallel arrangements of the second raised strips 502, with the spacing between them, ensure that regardless of the worker's posture, their feet can simultaneously contact multiple strips, maximizing friction. Furthermore, the grooves between the raised strips quickly drain away accumulated water and oil, keeping the working surface dry.

[0037] In an optional embodiment, the thickness of the first protrusion 501 and the second protrusion 502 is 10mm-15mm. When the thickness is less than 10mm, the protrusion is prone to wear and flattening under prolonged foot traffic, rapidly diminishing its anti-slip effect; a thickness greater than 15mm will cause discomfort underfoot, affecting the operator's precision and comfort. A thickness of 10mm-15mm ensures sufficient wear resistance for high-intensity use in hot rolling production environments while providing a comfortable walking experience for operators. In high-temperature environments, this thickness of protrusion also exhibits good thermal stability, preventing deformation due to thermal expansion and maintaining its anti-slip effect.

[0038] In an optional implementation, the width of the working surface is not less than 20cm. A width of 20cm is sufficient to fully accommodate an adult standing with both feet side-by-side, providing a stable triangular support posture for the operator, which is especially important in scenarios requiring precise operation of the pneumatic butterfly valve 601. A width less than 20cm would cause the operator to be unstable and sway, affecting not only operational accuracy but also increasing safety risks. While a wider working surface offers better stability, it increases material costs and device weight. The 20cm width also takes into account the space constraints of the hot rolling site, ensuring that the guard plate assembly can be installed and used within a limited space without interfering with surrounding equipment or pipelines.

[0039] like Figure 1 , Figure 2 As shown, in an optional embodiment, the connecting assembly 300 includes a first connecting plate 301 and a second connecting plate 302 that are vertically connected, with the first connecting plate 301 fixedly connected to the upright plate assembly 100.

[0040] The connecting assembly 300 is vertically connected by a first connecting plate 301 and a second connecting plate 302. The two vertically connected connecting plates form a stable L-shaped structure, which has extremely high torsional stiffness and can effectively resist torques in various directions generated during operation, preventing the connection from loosening. The fixed connection between the first connecting plate 301 and the upright plate assembly 100 can also be reinforced with reinforcing ribs to ensure the continuity of the load transmission path, avoid structural failure caused by stress concentration, and improve the reliability and service life of the entire guard plate assembly.

[0041] like Figure 1 , Figure 2 As shown, in an optional embodiment, the first connecting plate 301 and / or the second connecting plate 302 are fixedly connected to the base 603 on one side of the laminar flow roller 602 by bolts 303.

[0042] In the hot rolling production environment, the connecting assembly 300 can be disassembled to adapt to different operating positions. The bolt 303 connection provides convenience for quick installation and disassembly while ensuring sufficient connection strength. The use of high-strength bolts 303 in conjunction with anti-loosening washers maintains connection reliability even under vibration. When a connecting plate is damaged, it is not necessary to replace the entire guard plate assembly; only the damaged part needs to be replaced, significantly reducing maintenance costs. This allows the guard plate assembly to adapt to different specifications of laminar flow rollers 602, improving the versatility and adaptability of the equipment.

[0043] like Figure 1 , Figure 2 As shown, based on the same inventive concept, this application also provides a hot-rolled laminar flow cooling production system, which includes the guard plate assembly as described above.

The presence of the guard plate assembly makes equipment maintenance operations more standardized and safer, reduces production interruptions caused by safety issues, improves the operating efficiency of the entire system, and facilitates standardized management.
