Description

Technical Field

[0001] The utility model relates to the technical field of steel bar coil storage, in particular to a steel bar coil storage plant. Background Art

[0002] In the production process of steel bars, after the steel bars are qualified, certain types of steel bars need to be rolled into steel bar coils and then transported to designated places. Before leaving the factory, they are piled up in the factory. The steel bar coil is generally a hollow cylindrical structure wound with a steel bar. The diameter of the steel bar coil is generally about one meter. Because the hollow part of the steel bar coil needs to be hooked when the steel bar coil is hoisted, the steel bar coil is generally stacked vertically, and the number of stacked layers does not exceed three. However, since the steel bar coil is round, the stability is poor when stacked vertically, and it is easy to roll and collapse, leading to safety accidents. Utility Model Content

[0003] The utility model aims to provide a storage plant for steel bar coils, which effectively avoids the risk of rolling and collapsing during the stacking of steel bar coils and reduces the occurrence rate of safety accidents.

[0004] In order to solve the above technical problems, the utility model adopts the following solutions:

[0005] A storage building for steel bar coils comprises a building body, wherein the inner bottom surface of the building body is a concrete hardened surface, a downwardly recessed storage pit is arranged on the concrete hardened surface, an adaptive support platform is installed on the bottom wall of the storage pit, a plurality of support parts for placing steel bar coils are distributed in a matrix manner on the support platform, the steel bar coils are vertically stacked in multiple layers in the storage pit, a fence is arranged circumferentially on the top of the storage pit, and a gantry crane is arranged outside the fence.

[0006] Due to the adoption of the above technical solution, the main body of the plant provides a stable infrastructure for the entire storage system, ensuring the safety and reliability of the storage environment. The concrete hardening treatment on the bottom surface of the main body of the plant not only enhances the bearing capacity of the ground, but also helps to keep the ground flat and clean. The adapter support platform and support parts installed on the bottom wall of the storage pit provide stable support for the steel coils. The support parts are distributed in a matrix manner to ensure that each steel coil is evenly supported, preventing deformation or damage caused by uneven force. The fence set around the top of the storage pit not only plays a role in safety protection, but also prevents people or equipment from accidentally falling into the storage pit. It also helps to keep the storage environment clean and orderly. The gantry crane installed outside the fence provides convenience for the lifting and handling of the steel coils. The gantry crane has a large lifting capacity and operating range, and can efficiently complete the lifting and stacking of the steel coils, improving work efficiency. The storage pit that is sunken downward on the concrete hardened surface can effectively utilize the space, allowing the steel coils to be stacked in multiple layers, breaking the limitation of three-layer stacking, thereby increasing the storage capacity. At the same time, the storage pit also makes the steel coils more stable during storage. The stacked steel coils are confined in the storage pit, reducing the risk of collapse caused by external forces or natural factors, and reducing the incidence of safety accidents. Even if a collapse accident occurs, the steel coils are confined in the storage pit, and safety accidents are not likely to occur.

[0007] Optionally, a plurality of the storage pits are arranged at intervals along the width direction of the main body of the factory building, and at the same time, a plurality of the storage pits are arranged at intervals along the moving path of the gantry crane.

[0013] Optionally, a waterproof layer is provided between the concrete layer and the geology on the side.

[0014] Optionally, a water absorbing layer is provided on the side wall of the storage pit, and the water absorbing layer is composed of a desiccant.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0026] A storage building for steel bar coils includes a building body 1, the inner bottom surface of the building body 1 is a concrete hardened surface 11, a downwardly recessed storage pit 17 is provided on the concrete hardened surface 11, a matching support platform 7 is installed on the bottom wall of the storage pit 17, a plurality of support parts for placing steel bar coils 9 are distributed in a matrix manner on the support platform 7, the steel bar coils 9 are vertically stacked in multiple layers in the storage pit 17, a fence 3 is circumferentially provided on the top of the storage pit 17, and a gantry crane 2 is provided on the outside of the fence 3.

[0027] In this embodiment, Figure 1As shown, the main body of the plant 1 provides a stable infrastructure for the entire storage system, ensuring the safety and reliability of the storage environment. The concrete hardening treatment on the bottom surface of the main body of the plant 1 not only enhances the bearing capacity of the ground, but also helps to keep the ground flat and clean, making it convenient for workers to walk. The adapter support platform 7 and the support part installed on the bottom wall of the storage pit 17 provide stable support for the steel coil 9. The support parts are distributed in a matrix manner to ensure that each steel coil 9 is evenly supported, preventing deformation or damage caused by uneven force. The fence 3 arranged circumferentially on the top of the storage pit 17 not only plays a role in safety protection, preventing people or equipment from accidentally falling into the storage pit 17, but also It helps to keep the storage environment clean and orderly. The gantry crane 2 set outside the fence 3 provides convenience for the lifting and transportation of the steel bar coil 9. The gantry crane 2 has a large lifting capacity and operating range, and can efficiently complete the lifting and stacking of the steel bar coil 9, thereby improving work efficiency. The storage pit 17 that is recessed downward on the concrete hardened surface 11 can effectively utilize the space, so that the steel bar coil 9 can be stacked in multiple layers, breaking the limitation of three-layer stacking, thereby increasing the storage capacity. At the same time, the storage pit 17 also makes the steel bar coil 9 more stable during storage. The stacked steel bar coil 9 is confined in the storage pit 17, reducing the risk of collapse caused by external forces or natural factors, and reducing the incidence of safety accidents. Even if a collapse accident occurs, the steel bar coil 9 is confined in the storage pit 17, and safety accidents are not likely to occur.

[0028] Furthermore, a plurality of storage pits 17 are arranged at intervals along the width direction of the factory building body 1 , and at the same time, a plurality of storage pits 17 are arranged at intervals along the moving path of the gantry crane 2 .

[0029] Specifically, Figure 3As shown, by setting up a plurality of storage pits 17 in the width direction of the main body of the factory building 1, the horizontal space of the factory building can be fully utilized to increase the storage capacity of the steel bar coils 9. The setting of a plurality of storage pits 17 can also classify and store the steel bar coils 9 according to different specifications and types, which is convenient for management and retrieval. A plurality of storage pits 17 are arranged at intervals along the moving path of the gantry crane 2: the gantry crane 2 is an important lifting equipment in the factory building, and its moving path determines the convenience of the transportation of the steel bar coils 9. Arranging a plurality of storage pits 17 at intervals on the moving path of the gantry crane 2 can ensure that the gantry crane 2 can conveniently access each storage pit 17 during the movement to lift and stack the steel bar coils 9. This design can reduce the moving distance and idle time of the gantry crane 2 and improve work efficiency. The size and depth of the storage pits 17 need to be reasonably designed according to the specifications and stacking layers of the steel bar coils 9 to ensure the stability and safety of storage. The intervals between the storage pits 17 also need to be reasonably planned according to the size and operation requirements of the gantry crane 2 to avoid mutual interference. Appropriate passages and transportation equipment are also required to be set up inside the factory building to transport the steel bar coils 9 out of or into the storage pits 17. In summary, by arranging a plurality of storage pits 17 at intervals in the width direction of the factory building main body 1 and arranging a plurality of storage pits 17 at intervals on the moving path of the gantry crane 2, the storage efficiency and operational flexibility of the steel bar coils 9 can be further improved, making the storage plant more efficient and practical.

[0030] Furthermore, the support portion is a downwardly concave arc groove 8 , the curvature of the arc groove 8 is adapted to the steel bar coil 9 , and the length of the arc groove 8 is adapted to the width of the steel bar coil 9 .

[0031] Specifically, Figure 1 As shown, the curvature design of the arc groove 8 is determined based on the outer contour of the steel bar coil 9, ensuring that the curvature of the arc groove 8 matches the curvature of the steel bar coil 9, which can ensure that the steel bar coil 9 can be stably placed on the support platform 7 during storage, and is not easy to slide or roll, thereby reducing the occurrence of safety accidents. The adaptive curvature design can also make the steel bar coil 9 evenly stressed during storage, avoiding deformation or damage caused by uneven stress. The length design of the arc groove 8 is determined according to the width of the steel bar coil 9, ensuring that the length of the arc groove 8 is sufficient to accommodate the width of the steel bar coil 9, so that the steel bar coil 9 can be completely placed on the support platform 7 during storage. On the platform 7, there will be no hanging or instability. The adaptive length design can also improve the utilization rate of the storage space, so that more steel coils 9 can be accommodated in the storage pit 17. The surface of the arc groove 8 should be properly treated, such as anti-slip coating or anti-slip texture, to increase the friction between the steel coil 9 and prevent sliding. In summary, the design of the downwardly concave arc groove 8 as the support part can ensure the stability and safety of the steel coil 9 in the storage plant. Through the adaptive curvature and length design, the steel coil 9 can be evenly stressed and stably placed during storage, and the storage space can be fully utilized.

[0032] Furthermore, the support portion is an upwardly protruding support seat 15 , and a groove 16 adapted to the steel bar coil 9 is provided on the top of the support seat 15 .

[0033] Specifically, Figure 2 As shown, in the steel bar coil 9 storage plant, the support part is an important structure for supporting the steel bar coil 9. The support part designed this time is an upwardly protruding support seat 15, and a groove 16 adapted to the steel bar coil 9 is provided on the top thereof. This design is intended to ensure the stability and safety of the steel bar coil 9 during storage. The support seat 15 adopts an upwardly protruding structure, which is conducive to enhancing the stability and load-bearing capacity of the support seat 15. This design can ensure that the support seat 15 will not deform or sink when bearing the weight of the steel bar coil 9. A groove 16 adapted to the steel bar coil 9 is provided on the top of the support seat 15. The curvature, width and depth of the groove 16 are precisely designed according to the actual size of the steel bar coil 9 to ensure that the steel bar coil 9 can be stably Placed in the groove 16, it is not easy to slide or roll. The support seat 15 should be made of materials with sufficient strength and durability, such as high-quality steel or concrete. These materials can withstand the weight of the steel coil 9 and the wear and tear of long-term use, ensuring the stability and service life of the support seat 15. The upwardly protruding support seat 15 and the adaptive groove 16 design enable the steel coil 9 to maintain a stable state during storage, reducing the risk of collapse due to external force or natural factors. The adaptive groove 16 design makes the placement and removal of the steel coil 9 more convenient and quick, thereby improving work efficiency. By accurately designing the size and position of the groove 16, the storage space can be maximized and the storage density of the steel coil 9 can be increased.

[0034] Furthermore, the bottom surface of the support platform 7 is a flat concrete layer 10 , and the side wall of the storage pit 17 is a concrete layer 10 .

[0035] Specifically, Figure 1 As shown, the bottom surface of the support platform 7 adopts a flat concrete layer 10 with good stability: the concrete layer 10 has extremely high strength and stability, and can withstand the weight and pressure from the steel coil 9 above, ensuring that the support platform 7 will not deform or sink due to the load-bearing. High flatness: after the construction of the concrete layer 10, a very flat surface can be formed, which is very important for the installation of the support seat 15 on the support platform 7 and the placement of the steel coil 9. The flat surface can ensure that the support seat 15 is installed firmly and the steel coil 9 is placed stably. Strong durability: the concrete material has good durability and can resist the erosion of external factors such as corrosion and wear, ensuring that the bottom surface of the support platform 7 will not be deformed or damaged during long-term use.

[0036] The side walls of the storage pit 17 also use the concrete layer 10. The structure is solid: the side walls of the concrete layer 10 can provide strong support to ensure the stability and safety of the structure of the storage pit 17. Even when a large number of steel coils 9 are stored, the side walls can remain stable to prevent the pit wall from collapsing. Good waterproof performance: The concrete material has good waterproof performance and can effectively prevent the infiltration of groundwater or other liquids, which is essential for keeping the environment in the storage pit 17 dry and clean, which is conducive to the long-term storage of steel coils 9. Long durability: The concrete side walls also have the characteristics of strong durability and can withstand the test of long-term use and environmental changes, reducing the need for maintenance and repair. In the steel coil 9 storage plant, the bottom surface of the support platform 7 and the side walls of the storage pit 17 are designed with a flat concrete layer 10, which can not only provide a stable and solid structural support, but also have excellent durability and waterproof performance. This design helps to ensure the safety and stability of the steel coils 9 during storage, and is a recommended choice in the design of storage plants.

[0037] Furthermore, the side wall of the storage pit 17 is an inclined surface inclined downward.

[0038] Furthermore, the angle between the side wall of the storage pit 17 and the plane where the top surface of the support platform 7 is located is greater than 90° and less than 110°.

[0039] Specifically, Figure 1 As shown, the side wall of the storage pit 17 is designed as a downward inclined surface. This design not only optimizes the use of storage space, but also improves the efficiency of storage and management. Specifically, the downward inclined surface design has the following advantages:

[0040] The downwardly inclined side walls enable the storage pit 17 to accommodate more steel bar coils 9 in the depth direction, thereby increasing the storage capacity. The inclined side walls can enhance the stability of the storage pit 17 and reduce the risk of collapse.

[0041] The angle between the side wall of the storage pit 17 and the plane where the top surface of the support platform 7 is located is designed to be greater than 90° and less than 110°. The selection of this angle range is based on the following considerations:

[0042] Stability: The angle is greater than 90°, that is, the side wall is inclined relative to the top surface of the support platform 7, which can ensure the structural stability of the storage pit 17 and prevent the risk of collapse caused by the side wall being too steep.

[0043] Operability: The angle is less than 110°, which ensures that when storing and taking out the steel bar coil 9, personnel or equipment can operate conveniently without increasing the difficulty of operation due to excessive angle.

[0044] Furthermore, a waterproof layer 6 is provided between the concrete layer 10 and the geology 12 on the side.

[0045] Specifically, Figure 1 As shown, in the storage building for the steel bar coils 9, a waterproof layer 6 is provided between the concrete layer 10 and the side geology 12, which is an important measure to ensure the stability of the storage environment and the safe storage of the steel bar coils 9. The main function of the waterproof layer 6 is to prevent groundwater or other water sources from infiltrating into the storage pit 17, causing the steel bar coils 9 to get damp, rust, and even cause other safety problems. The waterproof layer 6 should be made of materials with excellent waterproof performance, strong durability, anti-aging, and anti-corrosion. Common waterproof materials include waterproof membranes, waterproof coatings, etc. These materials can effectively block the penetration of water molecules to ensure that the interior of the storage pit 17 remains dry. The angle between the side wall of the storage pit 17 and the top surface of the support platform 7 should be greater than 90° and less than 110°. This angle range helps to ensure that the waterproof layer 6 can fit tightly between the concrete layer 10 and the geology 12, thereby improving the waterproof effect. By providing the waterproof layer 6, groundwater or other water sources can be effectively prevented from infiltrating into the storage pit 17, and the interior of the storage pit 17 can be kept dry. This can not only prevent the steel coil 9 from getting damp and rusting, but also prevent moisture from damaging the structure of the storage pit 17, thereby extending the service life of the storage pit 17. At the same time, the waterproof layer 6 can also improve the safety of the storage environment and reduce the risk of safety accidents caused by moisture infiltration.

[0046] Furthermore, a water absorbing layer 14 is provided on the side wall of the storage pit 17, and the water absorbing layer 14 is composed of a desiccant.

[0047] Specifically, in the steel coil 9 storage plant, the side wall design of the storage pit 17 is crucial to maintaining a dry storage environment. In order to ensure that the interior of the storage pit 17 is dry and prevent the steel coil 9 from getting damp, rusting, and other problems, it is particularly important to design an effective water-absorbing layer 14, especially in areas with high groundwater levels or high humidity. The water-absorbing layer 14 is composed of a desiccant, which is a chemical substance that can absorb moisture from the air and has good hygroscopic properties. Commonly used desiccants include silica gel, activated carbon, calcium chloride, etc. The desiccant can be attached to the side wall of the storage pit 17 by brushing, spraying or laying to form a dense water-absorbing layer 14. This water-absorbing layer 14 can effectively absorb moisture from the air in the storage pit 17 and reduce the humidity inside the storage pit 17. The water-absorbing layer 14 should be evenly distributed on the side wall of the storage pit 17 to ensure Each area can be fully protected. At the same time, the thickness or density of the water-absorbing layer 14 can be appropriately increased at the corners, joints and other places on the side walls where water is easily accumulated to improve the moisture absorption effect. By arranging a water-absorbing layer 14 composed of a desiccant on the side wall of the storage pit 17, it is possible to effectively absorb moisture in the air and reduce the humidity inside the storage pit 17. This can not only prevent the steel coil 9 from getting damp, rusting and other problems, but also improve the quality of the storage environment, and improve the safety and storage efficiency of the steel coil 9. In summary, the design of the water-absorbing layer 14 on the side wall of the storage pit 17 is an important waterproof measure in the storage building of the steel coil 9. By selecting a suitable desiccant, controlling the thickness and distribution of the water-absorbing layer 14, and regularly checking and replacing the water-absorbing layer 14, it is possible to ensure that the inside of the storage pit 17 remains dry, providing a strong guarantee for the safe storage of the steel coil 9.

[0048] Furthermore, a fan 5 is provided on the top side of the storage pit 17, and the air outlet 4 of the fan 5 is connected to the air duct 13, the air duct 13 extends into the storage pit 17, and the air duct 13 is distributed in a ring shape on the side wall of the storage pit 17, and a plurality of air outlets 4 are provided on the side wall of the air duct 13.

[0049] Specifically, Figure 1 As shown, in the steel bar coil 9 storage workshop, a ventilation system is specially designed to keep the internal environment of the storage pit 17 ventilated and dry and to improve the storage conditions. A fan 5 is arranged on the top side of the storage pit 17. As the power source of the ventilation system, the fan 5 should have sufficient power and an appropriate model to ensure that sufficient ventilation can be provided, and should be reasonably arranged according to the size and shape of the storage pit 17. The air outlet 4 of the fan 5 is connected to the inside of the storage pit 17 through the air duct 13. The air duct 13 adopts a ring design and is distributed on the side wall of the storage pit 17 to ensure the uniformity and effectiveness of ventilation. The material of the air duct 13 should be corrosion-resistant, wear-resistant, and high-temperature resistant to adapt to the environmental conditions inside the storage pit 17, such as Figure 4As shown, a plurality of air outlets 4 are provided on the side wall of the air duct 13, and the air outlets 4 can face the steel bar coil 9. Through the annularly distributed air duct 13, uniform ventilation inside the storage pit 17 is achieved, ensuring that every corner can get good ventilation effect. The air outlet 4 faces the steel bar coil 9, which can directly ventilate the steel bar coil 9, improve the ventilation effect, and reduce the risk of the steel bar coil 9 getting damp and rusting. The fan 5 and the air duct 13 system should be adjustable and can be adjusted according to the humidity and temperature conditions inside the storage pit 17 to meet the needs of different storage conditions. The storage pit 17 ventilation system realizes effective ventilation and humidity control inside the storage pit 17 through a combination of key parts such as the fan 5, the air duct 13 and the air outlet 4. The system has the characteristics of uniform ventilation, strong pertinence, and adjustability, can significantly improve the environmental conditions inside the storage pit 17, reduce the risk of the steel bar coil 9 getting damp and rusting, and provide a strong guarantee for the safe storage of the steel bar coil 9.

[0050] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
