Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a positioning mechanism for installing transformers. Background Art

[0002] Transformers are core equipment in power grid systems and are often used to achieve voltage conversion and transmission. When installing transformers, screws or bolts are usually used to fix the transformers to brackets or bases. However, the transformers are large in size and weight, making it difficult to move them, which results in inconvenience in aligning the fixing holes and affects installation efficiency. If the diameter of the fixing holes is increased, the transformer may be easily installed loosely, causing the transformer to shift or shake, which in turn may cause the internal structure of the transformer to loosen or external components to be damaged, affecting the reliable operation of the transformer.

[0003] Therefore, a device is needed to facilitate the mutual positioning of fixing holes during the installation of the transformer. Utility Model Content

[0005] The utility model is realized by the following technical scheme, which provides a positioning mechanism for installing a transformer, including a base fixedly connected to a base on which the transformer is placed, and a fixing frame fixedly connected to the transformer, wherein the base and the fixing frame are provided with fixing holes corresponding to each other; a plurality of inverted cone-shaped positioning grooves are provided on the top of the base, and a plurality of positioning protrusions matched with the positioning grooves are provided at corresponding positions of the bottom of the fixing frame; the positioning protrusions on the fixing frame and the positioning grooves on the base facilitate accurate positioning of the fixing frame on the base, thereby facilitating the fixing of the fixing frame and the base.

[0006] As an optimization, the bottom of the positioning protrusion is a spherical arc surface, and the center of the spherical arc surface is located directly above the bottom of the positioning protrusion; the spherical arc surface prevents the positioning protrusion from causing damage to the base.

[0008] As an optimization, the base includes a bottom plate fixedly connected to the base, and a connecting plate is fixedly connected to the bottom plate through a support plate; a gap is formed between the bottom plate and the connecting plate, the positioning groove is located at the top of the connecting plate, and the positioning rod passes through the positioning hole and penetrates the connecting plate; a limiting hole with an axis parallel to the bottom of the connecting plate is formed at the part where the positioning rod passes through the connecting plate, and a limiting rod that fits with the bottom of the connecting plate is inserted into the limiting hole; the limiting rod and the limiting hole prevent the positioning rod from sliding upward in the positioning hole, thereby preventing the transformer and the fixing frame from shifting.

[0009] As an optimization, a limiting ring is fixedly arranged at one end of the limiting rod away from the positioning rod, and the limiting rod is fixedly connected to the base through a bolt passing through the limiting ring and the fixing hole; the limiting rod is fixedly connected to the base through the limiting ring and the bolt, preventing the limiting rod from detaching from the limiting hole, thereby preventing the positioning rod from sliding upward in the positioning hole.

[0010] The beneficial effects of the present utility model are as follows: The positioning protrusion on the fixing frame and the positioning groove on the base facilitate the precise positioning of the fixing frame on the base, thereby facilitating the fixation between the fixing frame and the base; the spherical arc surface prevents the positioning protrusion from damaging the base; the positioning rod and the positioning hole prevent the transformer and the fixing frame from shifting; the limiting rod and the limiting hole prevent the positioning rod from sliding upward in the positioning hole, thereby preventing the transformer and the fixing frame from shifting; the limiting rod is fixedly connected to the base through the limiting ring and the bolt, preventing the limiting rod from detaching from the limiting hole, thereby preventing the positioning rod from sliding upward in the positioning hole.
