Reinforcing plates are welded to the left and right sides and the front and rear sides of the shell. The top of the reinforcing plate is flush with the top of the shell, and the bottom of the reinforcing plate is flush with the bottom of the shell. A hook protrudes outward from the upper end of the reinforcing plate, and the lower end of the hook is concave. The hook is integrally formed with the reinforcing plate, and the height of the reinforcing plate is the same as the height of the shell. This increases the area of ​​the reinforcing plate in contact with the shell, dissipating the stress on the reinforcing plate and thus increasing its strength. This prevents deformation of the shell or cracking between the shell and the reinforcing plate. The reinforcing plates are welded to the left and right sides and the front and rear sides of the shell. Hoisting ropes can be used to pull the shell from all sides, preventing deformation during movement. The lower end of the hook is concave, and the hook is used for binding with the hoisting rope.

Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer hoisting structure. Background Technology

[0002] Transformers, as core power transmission and transformation equipment in the power grid, are enormous and heavy, ranging from several tons to hundreds of tons. Therefore, during production, transportation, and on-site installation, they must be lifted using specialized hoisting structures. The safety of hoisting operations directly affects the safety of the equipment itself, the integrity of surrounding facilities, and the lives of operators; thus, the reliability of the hoisting structure is a crucial aspect of transformer design.

[0003] Currently, the primary technology used is to weld lifting lugs or rings onto the outside of the transformer casing. While this method is common, its stress resistance relies entirely on the strength of the weld. Under prolonged heavy loads, especially impact loads (such as during lifting, emergency braking, or accidental collisions), stress concentration can easily occur at the weld, posing a risk of cracking. Weld failure can lead to serious lifting accidents.

[0004] Furthermore, in existing technologies, even when externally welded reinforcement structures are used, the reinforcing plates are typically only used for localized reinforcement (e.g., welding a small steel plate only around the lifting point). This localized reinforcement results in a limited contact area between the reinforcing plate and the main shell, leading to an unsmooth stress transmission path. During hoisting, the enormous tensile force acts not only on the lifting point but also generates significant bending and tensile stresses on the shell itself. Localized reinforcement cannot effectively suppress the deformation of the entire shell, and in the long run, this may lead to irreversible plastic deformation of the shell steel plates, affecting the mechanical life and sealing performance of the equipment. Utility Model Content

[0005] To address the aforementioned deficiencies, the purpose of this utility model is to propose a transformer hoisting structure in which reinforcing plates are installed on the front, rear, left, and right side walls of the housing, and the height of the reinforcing plates is consistent with the height of the housing, so that the reinforcing plates are tightly fitted and fixed to the side walls of the housing.

[0006] To achieve this objective, the present invention adopts the following technical solution: A transformer hoisting structure includes a housing and reinforcing plates. The reinforcing plates are welded to the left and right sides and the front and rear sides of the housing, respectively. The top of the reinforcing plate is flush with the top of the housing, and the bottom of the reinforcing plate is flush with the bottom of the housing. The upper end of the reinforcing plate has a hook protruding outward, and the lower end of the hook is concave. The hook is integrally formed with the reinforcing plate.

[0007] Preferably, two reinforcing plates are provided on the left side of the housing, and the two reinforcing plates are respectively provided on both sides of the left side of the housing; two reinforcing plates are provided on the right side of the housing, and the two reinforcing plates are respectively provided on both sides of the right side of the housing.

[0008] Preferably, four reinforcing plates are provided on the front side of the housing, and the four reinforcing plates are evenly distributed; four reinforcing plates are provided on the rear side of the housing, and the four reinforcing plates are evenly distributed.

[0009] Preferably, the top of the housing is provided with a top plate, which is disposed along the top wall of the housing and protrudes out of the outer wall of the housing.

[0010] Preferably, the top of the reinforcing plate is welded to the bottom of the top plate.

[0011] Preferably, support columns are provided around the bottom of the housing.

[0012] Preferably, the bottom of the support column protrudes outward, and the bottom of the support column is provided with mounting holes.

[0013] Preferably, the support column has a fixing hole arranged laterally in the middle.

[0014] The technical solution provided by this utility model can include the following beneficial effects: the top of the reinforcing plate is flush with the top of the shell, and the bottom of the reinforcing plate is flush with the bottom of the shell, which can increase the area of ​​the reinforcing plate in contact with the shell, disperse the stress on the reinforcing plate, avoid concentration, thereby increasing the strength and preventing the shell from deforming or cracking between the shell and the reinforcing plate. Reinforcing plates are welded to the left and right sides and the front and back sides of the shell respectively. The lifting rope can be pulled from all sides of the shell to move the whole, preventing the shell from deforming during the pulling process. The lower end of the hook is concave arc-shaped, and the hook is used for binding the lifting rope. The hook and the reinforcing plate are integrally formed, which enhances the hardness between the hook and the reinforcing plate. Attached Figure Description

[0020] The following is combined Figures 1 to 2 This describes a transformer hoisting structure according to an embodiment of the present utility model.

[0021] A transformer hoisting structure includes a housing 1 and a reinforcing plate 2. The reinforcing plate 2 is welded to the left and right sides and the front and rear sides of the housing 1 respectively. The top of the reinforcing plate 2 is flush with the top of the housing 1, and the bottom of the reinforcing plate 2 is flush with the bottom of the housing 1. The upper end of the reinforcing plate 2 has a hook 3 protruding outward, and the lower end of the hook 3 is concave arc-shaped. The hook 3 is integrally formed with the reinforcing plate 2.

[0022] A transformer hoisting structure facilitates hoisting. The top and bottom of the reinforcing plate 2 are flush with the top of the shell 1, increasing the contact area between the reinforcing plate 2 and the shell 1, thus dispersing stress and preventing concentration. This increases strength and prevents deformation of the shell 1 or cracking between the shell 1 and the reinforcing plate 2. Reinforcing plates 2 are welded to the left, right, front, and rear sides of the shell 1. Hoisting ropes can pull the shell 1 from all sides for overall movement, preventing deformation during pulling. The lower end of the hook 3 is concave, and the hook 3 is used for securing the hoisting rope. The hook 3 is integrally formed with the reinforcing plate 2, enhancing the rigidity between the hook 3 and the reinforcing plate 2.

[0023] Specifically, two reinforcing plates 2 are provided on the left side of the shell 1, respectively on both sides of the left side of the shell 1; two reinforcing plates 2 are provided on the right side of the shell 1, respectively on both sides of the right side of the shell 1. During the movement of the shell 1, the reinforcing plates 2 on the left side of the shell 1 and the two reinforcing plates 2 on the right side of the shell 1 enable the shell 1 to move smoothly on both sides and enhance the tensile strength.

[0024] Specifically, four reinforcing plates 2 are provided on the front side of the shell 1, and the four reinforcing plates 2 are evenly distributed; four reinforcing plates 2 are provided on the rear side of the shell 1, and the four reinforcing plates 2 are evenly distributed. During the movement of the shell 1, the four reinforcing plates 2 on the front side of the shell 1 enable the shell 1 to move smoothly on both the front and rear sides, and can enhance the tensile strength.

[0025] Specifically, a top plate 4 is provided on the top of the shell 1. The top plate 4 is provided along the top wall of the shell 1, and the outer side of the top plate 4 protrudes from the outer wall of the shell 1. The top plate 4 is used for the shell 1 and the cover to fit together. The outer side of the top plate 4 protrudes from the outer wall of the shell 1, which increases the area and facilitates fitting with the cover.

[0026] To further explain, the top of the reinforcing plate 2 is welded to the bottom of the top plate 4, thus fixing the reinforcing plate 2 to the side wall of the housing 1.

[0027] Specifically, support columns 5 are provided around the bottom of the shell 1. The support columns 5 support the shell 1 and prevent the shell 1 from directly contacting the ground. If there is water on the ground, the shell 1 can avoid contact with the water.

[0028] Specifically, the bottom of the support column 5 protrudes outwards, and a mounting hole 6 is provided at the bottom of the support column 5. The mounting hole 6 facilitates the fixed installation of the housing. Bolts are inserted into the mounting hole 6 and then screwed into the mounting surface for fixed installation. The mounting surface mentioned here refers to the surface on which the cover transformer will be installed.

[0029] Specifically, a fixing hole 7 is provided laterally in the middle of the support column 5. When transporting the transformer, a rope can be passed through the fixing hole 7 to secure the transformer. Additionally, when installing the transformer, a rope can be passed through the fixing hole 7 to further secure the transformer.

[0030] Other components and operations of the transformer hoisting structure according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
