Description
Technical Field
[0001] The utility model relates to the field of transformer hanging plates, in particular to a transformer hanging plate reinforcement structure. Background Art
[0002] Transformer core inspection is an important and complex process, which needs to be carried out after the transformer is powered off. The inspection includes appearance, cleaning, insulation, magnetic flux, temperature rise test and oil quality, etc., aiming to ensure the integrity and safety of the core. This process should be performed by professionals, paying attention to environmental humidity, temperature and other conditions to prevent damage to the core. Through this series of detailed inspections, potential problems can be discovered in time to ensure the normal operation and service life of the transformer, thereby ensuring the stability and safety of the power system. The whole process needs to be rigorous and meticulous, and is a key link in ensuring the performance and safety of the transformer.
[0003] The fixation between the transformer body and the box cover is traditionally achieved through the body hanger plate and the box cover angle steel, reference application number: 201721342072.X, a transformer hanger plate connection structure, using clamps and hangers to improve the convenience and stability of transformer hoisting. However, when the transformer capacity is large and its own weight increases, this traditional fixing method is prone to cause relatively concentrated hoisting stress during the core hoisting process, there is a risk of tearing the hanger plate, and reduces the safety during the core hoisting inspection process. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a transformer hanging plate reinforcement structure to solve the technical problem that the traditional fixing method has the risk of tearing when the transformer has a large capacity and a heavy weight.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer hanger plate reinforcement structure, including a hanger plate main body, a hanging assembly is arranged on the top of the hanger plate main body, the hanging assembly includes a reinforcing cross plate, reinforcing vertical plates are arranged on both sides of the reinforcing cross plate, a channel steel is welded and fixed to the top of the reinforcing vertical plate, a plurality of lifting grooves are opened on the channel steel, and a supporting rib is welded and fixed to the top of the reinforcing cross plate.
[0006] By adopting the above technical solution and utilizing the structure of reinforced horizontal plates, supporting ribs and reinforced vertical plates, the force originally concentrated on the lifting point can be effectively dispersed to a larger area, which means that the main body of the hanging plate will not be subjected to excessive force in a small area, thereby reducing the risk of tearing.
[0007] Furthermore, the cross sections of the supporting ribs and the reinforcing transverse plates are vertical structures, and both ends of the supporting ribs are welded and fixed to the channel steels.
[0008] By adopting the above technical solution, the vertical structure enhances the stability of the structure, and the vertical layout enables the supporting ribs to effectively bear and strengthen the force exerted on the cross plate, preventing it from deformation or breakage.
[0009] Furthermore, two reinforcing transverse plates are provided, and the reinforcing transverse plates and the reinforcing vertical plates are welded into an integral structure.
[0010] By adopting the above technical solution, the two reinforced cross plates increase the overall stability of the lifting assembly. The layout of the two reinforced cross plates enables the lifting structure to have double support when bearing the lifting force, thereby improving the bearing capacity and stability of the structure.
[0011] Furthermore, the plurality of lifting grooves are arranged linearly and equidistantly along the length line of the channel steel, and the lifting grooves are straight groove structures, which are used as supporting points for external lifting hooks.
[0012] By adopting the above technical solution, multiple lifting slots provide multiple uniform lifting points, which makes it easy to select a suitable lifting position according to actual needs. The equidistant arrangement ensures the balance and stability during the lifting process and prevents deflection or imbalance caused by improper position of the lifting point.
[0013] Furthermore, the reinforcing transverse plate, the reinforcing vertical plate and the hanging plate body are welded and fixed.
[0014] By adopting the above technical solution, welding fixation ensures the stability of the entire lifting structure, and the welding connection makes these components form a whole, which enhances the rigidity and bearing capacity of the lifting structure and can effectively resist various forces and vibrations during the lifting process.
[0015] Furthermore, a plurality of mounting holes are provided on the surface of the hanger plate body for providing bolt connection points with the transformer box body.
[0016] By adopting the above technical solution, the multiple mounting holes opened on the surface of the hanger plate body facilitate bolt connection with the transformer box. This connection method is stable and reliable, and can ensure the tightness and stability between the hanger plate body and the transformer box, and prevent relative movement or looseness during lifting or use.
[0017] Furthermore, the materials of the reinforcing transverse plates, supporting ribs, channel steels and reinforcing vertical plates are all Q420B.
[0018] By adopting the above technical solution, the strength and load-bearing capacity of the lifting structure are significantly improved. Q420B is a high-strength low-alloy steel with a yield strength of up to 420MPa. It can withstand large loads without being easily deformed or damaged.
[0019] In summary, the utility model mainly has the following beneficial effects:
[0020] 1. The utility model strengthens the horizontal plate, the supporting rib plate and the strengthening vertical plate. These structures play an important role. These strengthening structures are conducive to dispersing the lifting force concentrated on the top to the main body of the hanging plate, thereby avoiding the situation where the lifting force is too concentrated. This structure of dispersing the lifting force not only reduces the risk of tearing of the main body of the hanging plate during the lifting process, but also greatly improves the safety of the hanging core operation. Through these strengthening structures, the transformer hanging plate strengthening structure can withstand greater lifting force, and at the same time ensure the stability and reliability of the lifting process;
[0021] 2. The utility model significantly enhances the overall strength of the structure by arranging strong horizontal plates and reinforcing vertical plates, which are connected by a "#"-shaped welding structure. This cross-welding layout can disperse and transfer stress in multiple directions, making the entire lifting structure more stable and effectively resisting various forces and vibrations during the lifting process. At the same time, the "#"-shaped welding structure also improves the lifting performance. Through reasonable layout and optimization, the lifting points are strengthened and can withstand greater lifting forces, ensuring the safety and stability of the lifting process. In addition, this structure also improves the rigidity of the lifting components, reduces deformation and distortion during the lifting process, and further ensures the smooth progress of the lifting operation.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0028] The following describes an embodiment of the utility model based on its overall structure.
[0029] Embodiment 1:
[0030] A transformer suspension plate reinforcement structure, such as Figure 1-Figure 4 As shown, it includes a hanger plate body 1, and a hanging assembly 2 is arranged on the top of the hanger plate body 1. The hanging assembly 2 includes a reinforcing cross plate 201, and reinforcing vertical plates 204 are arranged on both sides of the reinforcing cross plate 201. A channel steel 203 is welded and fixed to the top of the reinforcing vertical plate 204, and a plurality of hanging grooves 205 are opened on the channel steel 203. A supporting rib 202 is welded and fixed to the top of the reinforcing cross plate 201. By utilizing the structure of the reinforcing cross plate 201, the supporting rib 202 and the reinforcing vertical plate 204, the force originally concentrated on the hanging point can be effectively dispersed to a larger area, which means that the hanger plate body 1 will not bear too much force in a small area, thereby reducing the risk of tearing. At the same time, this structure of dispersing the hanging force also improves the safety of the hanging core operation. Since the hanging force is evenly dispersed, the stress and vibration in the hanging process will also be effectively reduced, which not only protects the hanging transformer core, but also makes the entire hanging process more stable and controllable, thereby ensuring the safety of operators and equipment.
[0031] See also Figure 1 , Figure 2 , Figure 3 The cross-sections of the supporting ribs 202 and the reinforcing cross-plate 201 are vertical structures, and both ends of the supporting ribs 202 are welded and fixed to the channel steel 203. The vertical structure enhances the stability of the structure. The vertical layout enables the supporting ribs 202 to effectively withstand and strengthen the force exerted on the cross-plate 201 to prevent it from deformation or breakage. At the same time, both ends of the supporting ribs 202 are welded and fixed to the channel steel 203, further enhancing the stability of the entire hoisting assembly. The welding fixation ensures a close connection between the various components, so that the various components will not move or loosen relative to each other during the hoisting process, thereby improving the safety and reliability of the hoisting operation.
[0032] Embodiment 2:
[0033] See also Figure 1 , Figure 2 , Figure 3 There are two reinforcing transverse plates 201, and the reinforcing transverse plates 201 and the reinforcing vertical plates 204 are welded into one structure. The two reinforcing transverse plates 201 increase the overall stability of the lifting assembly 2. The layout of the two reinforcing transverse plates 201 enables the lifting structure to have double support when bearing the lifting force, thereby improving the bearing capacity and stability of the structure. At the same time, the reinforcing transverse plates 201 and the reinforcing vertical plates 204 adopt a welded into one structure to ensure a firm connection between the two. The welded into one structure not only enhances the integrity of the structure, but also effectively prevents loosening or breakage that may occur during use, thereby further improving the safety and reliability of the lifting structure.
[0034] See also Figure 1 , Figure 2 , Figure 4 , multiple lifting grooves 205 are arranged equidistantly along the length line of the channel steel 203. The lifting grooves 205 are in a straight groove structure and are used as the supporting points for external lifting hooks. Multiple lifting grooves 205 provide multiple uniform lifting points, which is convenient for selecting a suitable lifting position according to actual needs. The equidistant arrangement ensures the balance and stability during the lifting process and prevents deflection or imbalance caused by improper position of the lifting point. At the same time, the straight groove structure of the lifting groove 205 is simple and practical, which matches the supporting points for external lifting hooks and is convenient for lifting operations. The straight groove structure can ensure a stable connection between the hook and the lifting groove 205, and prevent slippage or accidental falling off during the lifting process, thereby improving the safety and efficiency of the lifting process.
[0035] See also Figure 1 The reinforcing horizontal plate 201 and the reinforcing vertical plate 204 are welded and fixed to the hanging plate body 1. The welding fixation ensures the stability of the entire lifting structure. The welding connection makes these components form a whole, enhances the rigidity and bearing capacity of the lifting structure, and can effectively resist various forces and vibrations during the lifting process. At the same time, the welding fixation also improves the safety and reliability of the lifting structure. Due to the firmness of the welding connection, the lifting structure will not loosen or break when bearing heavy loads, thereby ensuring the safe and smooth progress of the lifting operation.
[0036] See also Figure 1 A plurality of mounting holes 3 are provided on the surface of the hanger plate main body 1 for providing bolt connection points with the transformer box. The plurality of mounting holes 3 provided on the surface of the hanger plate main body 1 facilitate bolt connection with the transformer box. This connection method is stable and reliable, and can ensure the tightness and stability between the hanger plate main body 1 and the transformer box, and prevent relative movement or loosening during lifting or use. At the same time, the setting of the plurality of mounting holes 3 provides a flexible connection method, and different connection points can be selected according to actual needs, which not only improves the flexibility and applicability of lifting, but also enhances the safety and stability of the entire lifting structure.
[0037] See also Figure 1 , Figure 2 , Figure 3The materials of the reinforced cross plate 201, the supporting rib plate 202, the channel steel 203 and the reinforced vertical plate 204 are all Q420B, which significantly improves the strength and load-bearing capacity of the lifting structure. Q420B is a high-strength low-alloy steel with a yield strength of up to 420MPa. It can withstand large loads without being easily deformed or damaged. At the same time, Q420B material also has good welding performance and toughness, so that the various components of the lifting structure can be firmly connected together and can maintain stable performance in harsh working environments. The choice of this material not only enhances the safety and reliability of the lifting structure, but also extends its service life and reduces maintenance costs.
[0038] The implementation principle of the utility model is as follows: first, the bolts in the mounting holes 3 are removed to complete the disassembly operation of the hanger plate main body 1 and the bottom transformer box; then, the external lifting hook is hooked with the corresponding lifting groove 205 on the channel steel 203, and the inner core of the transformer is lifted and inspected; in the process of lifting the core, the reinforcing horizontal plate 201, the supporting rib plate 202 and the reinforcing vertical plate 204 are used to disperse the lifting force concentrated on the top to the hanger plate main body 1, avoiding the situation where the lifting force is concentrated, thereby reducing the risk of tearing of the hanger plate main body 1 and improving the safety of the core lifting operation.
