Detailed Implementation

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0019] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0020] Combination Figures 1 to 4 As shown, this utility model discloses a packaging structure for large transformers capable of being hoisted and transported, comprising: A bottom load-bearing frame is installed on the bottom surface of the large transformer; A top support frame is installed on top of the large transformer; A central connecting frame is arranged around the lateral periphery of the large transformer and connects the bottom load-bearing frame and the top support frame. The bottom load-bearing frame, the top support frame, and the middle connecting frame are all constructed with wooden strips as the main frame, and components for increasing the strength of the main frame are fixedly installed on the wooden strips.

[0021] Compared with existing wooden box packaging structures, this utility model has components fixed on the wooden strips to increase the strength of the bottom load-bearing frame, the top support frame, and the middle connecting frame. This compensates for the fragility of the wooden box packaging structure, effectively improves the mechanical strength of the entire packaging structure, and enables it to withstand the lifting and transportation of large transformers.

[0022] In one embodiment, the components used to increase the strength of the main frame are channel steel and / or angle steel. The extension direction of the channel steel / angle steel is consistent with the extension direction of the corresponding wooden strips and is approximately the same length as the corresponding wooden strips. The channel steel / angle steel is arranged along the length of the wooden strips, and the channel steel / angle steel metal components bear most of the bending normal stress, allowing the wooden strips to mainly play a role in maintaining the shape, thus completely solving the problem of instability under compression of pure wooden beams.

[0023] Furthermore, combined Figure 1 As shown, the bottom load-bearing frame includes sleepers 1, skids 2, and end timbers 4. Multiple skids 2 are arranged side-by-side at intervals, with channel steel 12 positioned on both sides of each skid 2. Multiple sleepers 1 are arranged side-by-side at intervals and are located on top of the skids 2. From a top-down view, the sleepers 1 are perpendicular to the multiple skids 2, with channel steel 12 positioned on both sides of each sleeper 1. There are two end timbers 4, located on top of the skids 2, respectively on both sides of the sleepers 1 and parallel to them. The multiple skids 2 arranged side-by-side laterally form the main support platform. The multiple sleepers 1 are laid at 90° angles on top of the skids 2, forming a grid pattern with the channel steel, which evenly distributes the vertical load across the multiple skids 2, preventing localized subsidence caused by single-point overload. The end timbers 4 strengthen the connection between the multiple skids 2.

[0024] Furthermore, combined Figure 4 As shown, the skid 2 and the channel steel 12 located on the sleeper 1 have vertically communicating through holes for the screw 10 fastener to pass through, for connecting the base of the large transformer. The screw 10 passes through the skid 2, the channel steel 12 on both sides of the sleeper 1, and the base of the transformer 14 in sequence from bottom to top, and then the bottom load-bearing frame is connected to the transformer 14 by bolts 11 cooperating with the screw 10.

[0025] Furthermore, combined Figure 1As shown, the bottom load-bearing frame also includes an auxiliary skid 3, which is fixed to the bottom of the outermost skid 2 and located at the middle of the skid 2. Angle steel 13 is provided on both sides of the auxiliary skid 3 along its length, and the angle steel 13 is fixedly connected to the bottom and sides of the skid 2. The auxiliary skid 3 allows for the formation of rope hanging positions on both sides along its length, and its location at the middle of the skid 2 effectively balances the force, reducing the risk of the packaging structure tilting during hoisting. The use of angle steel 13 at the contact point between the hoisting rope and the skid 2 strengthens areas of stress concentration.

[0026] Furthermore, combined Figure 2 As shown, the top support frame includes support timbers 5 and an outer frame 7. Multiple support timbers 5 are arranged side-by-side at intervals, and each support timber 5 is located in the middle of the inner side of the outer frame 7. Both ends of the support timbers 5 are connected to the outer frame 7 along their length. Channel steel is provided on both sides of the support timbers 5, and on the side where the outer frame 7 connects to the support timbers 5. The multiple support timbers 5 arranged side-by-side at intervals form a "grid-like" main load-bearing layer. The channel steel on the support timbers 5 disperses the stress generated during hoisting and transportation onto the multiple support timbers 5 and the channel steel 12, significantly improving the bending strength of the support timbers 5.

[0027] Furthermore, the top bracing frame also includes an external reinforcing timber 6, which is fixed to the outside of the outer frame 7 and located in the middle of the outer frame 7. Using the bracing timber 5 as the first line of defense, the external reinforcing timber 6 is added to the middle of the outside of the outer frame 7, serving as the second line of defense, allowing the external reinforcing timber 6 to actively bear the bending moment generated by the excessive span of the outer frame 7.

[0028] Furthermore, combined Figure 3 As shown, the central connecting frame has crisscrossing central reinforcing timber 8, which connects the bottom load-bearing frame and the top support frame. Channel steel is installed on the inner side of the longitudinal central reinforcing timber 8. The central reinforcing timber 8 adopts an orthogonal grid layout, connecting the bottom load-bearing frame and the top support frame into a whole. Channel steel is installed at the longitudinal central reinforcing timber 8, especially near the suspension rope, to ensure the strength of the central connecting frame.

[0029] In one embodiment, the large transformer packaging structure capable of being hoisted and transported further includes a panel 9, which covers the outer periphery of the central connecting frame and the outer side of the top supporting frame. The panel 9 completely covers the outer periphery of the central connecting frame and the outer side of the top supporting frame, forming a continuous closed surface that serves to block dust and other external foreign objects.

[0030] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
