Description

Technical Field

[0001] This utility model relates to the field of oil-immersed transformer technology, specifically to an oil-immersed transformer hoisting structure. Background Technology

[0002] Oil-immersed transformers are widely used in power systems as crucial equipment for voltage transformation and power distribution. Their widespread application stems primarily from their reliability and stability, enabling them to adapt to various environments and operating conditions. They can increase voltage from low levels, such as in high-voltage transmission, and decrease voltage from high levels, such as in household power transformation. They are also frequently used for voltage conversion and load distribution. Oil-immersed transformers have extensive applications in power systems and are an indispensable and vital piece of equipment.

[0003] During the hoisting of oil-immersed transformers, it is crucial to ensure their stability and smooth ascent. Significant shaking during the hoisting process can damage the transformer structure, such as broken porcelain insulators or damaged bushings, affecting its safe operation. Furthermore, oil-immersed transformers contain a large amount of insulating oil, and significant shaking could lead to oil leakage. Therefore, a suitable hoisting structure for oil-immersed transformers is essential to ensure installation quality and safety. Utility Model Content

[0006] Preferably, the hoisting structure includes a circular groove plate, the center of the upper surface of the circular groove plate is fixedly connected to the lower surface of the base plate, hoisting rings are fixedly connected to the four corners of the upper surface of the circular groove plate, the two sides of the circular groove plate are in contact with the inner ring wall of the column, the outer ring wall of the column is provided with a slot plate, and the inner cavity of the slot plate is engaged with the side wall of the circular groove plate, a threaded rod is fixedly connected to the side wall of the circular groove plate, the side wall of the threaded rod penetrates the side wall of the slot plate, and a threaded block is threadedly connected to the outer wall of the threaded rod.

[0007] Preferably, the inner ring wall of the slot plate and the side wall of the circular groove plate are semi-circular, and the slot plate and the circular groove plate form a complete circle after being joined together.

[0008] Preferably, the number of threaded rods is eight, and they are evenly and symmetrically arranged.

[0009] Preferably, the upper surface of the circular groove plate is provided with screw holes, and the number of screw holes is nine.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When hoisting an oil-immersed transformer, a hoisting structure is set at the bottom. The circular groove plate and slot plate in the hoisting structure have circular grooves that fit against the inner and outer walls of the column and are fastened by threaded rods and threaded blocks. Hoisting rings are set at the four corners of the surface and are fitted between the columns to slide and hoist the transformer, ensuring the stability of the hoisting process. After reaching the preset position, the threaded blocks are tightened to complete the first fixation, ensuring stability and smoothness during the hoisting process and avoiding large-scale shaking. It is only necessary to place the hoisting structure between the columns and select the appropriate size of the circular groove plate according to the spacing of the columns, without complicated operation steps.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides an oil-immersed transformer hoisting structure, including two columns 1 arranged symmetrically in the horizontal direction. The outer walls of the two columns 1 are provided with hoisting structures 2. A base plate 3 is provided at the center of the hoisting structure 2, and the base plate 3 is threadedly connected to the center of the hoisting structure 2 by bolts. An oil-immersed transformer 4 is fixedly connected to the center of the upper surface of the base plate 3.

[0017] The hoisting structure 2 includes a circular groove plate 21. The center of the upper surface of the circular groove plate 21 is fixedly connected to the lower surface of the base plate 3. Hoisting rings 22 are fixedly connected to the four corners of the upper surface of the circular groove plate 21. The two sides of the circular groove plate 21 are in contact with the inner ring wall of the column 1. The outer ring wall of the column 1 is provided with a slot plate 23, and the inner cavity of the slot plate 23 is engaged with the side wall of the circular groove plate 21. A threaded rod 24 is fixedly connected to the side wall of the circular groove plate 21. The side wall of the threaded rod 24 penetrates the side wall of the slot plate 23. A threaded block 25 is threadedly connected to the outer wall of the threaded rod 24.

[0018] The inner ring wall of the slot plate 23 and the side wall of the circular slot plate 21 are semi-circular, and the slot plate 23 and the circular slot plate 21 form a complete circle after being joined together.

[0019] There are eight threaded rods 24, which are evenly and symmetrically arranged.

[0020] The upper surface of the circular groove plate 21 has nine screw holes.

[0021] Working principle: During the hoisting of the oil-immersed transformer 4, the position of the column 1 is determined in advance, and the hoisting structure 2 is moved to the construction site. Then, a suitable size of circular slot plate 21 is selected according to the spacing of the columns 1. The circular slot plate 21 has semi-circular slots on both sides. First, the circular slot plate 21 is placed vertically between the columns 1, and then flipped horizontally so that the semi-circular slots on both sides fit against the inner ring wall of the column 1. The two sides then fit against the outer ring wall of the column 1 through the slot plate 23. At the same time as fitting, the slot plate 23 will engage with the circular slot plate 21. At the same time as engaging, the threaded rods 24 on both sides of the circular slot plate 21 will penetrate the slot plate 23. The threaded block 25 is threadedly connected to the threaded rod 24, leaving a certain gap without fully tightening. Then, the oil-immersed transformer 4 is installed by fitting the base plate 3 to the circular groove plate 21. The surface of the circular groove plate 21 has multiple sets of screw holes, which facilitates the fixing of the base plate 3 with bolts. After the oil-immersed transformer 4 is fixed, it is lifted by the lifting rings 22 set at the four corners. The lifting structure 2 is set between the columns 1 and slides against the columns 1 to ensure the stability of the lifting process. After reaching the preset position, the threaded block 25 is tightened to complete the first fixing, which facilitates the subsequent installation work.
