Description

Technical Field

[0001] This utility model relates to the field of transformer-related technology, specifically a handling device for transformer experiments. Background Technology

[0002] In power systems, transformers, as critical electrical equipment, undertake the important tasks of voltage conversion and power transmission. To ensure the performance and reliability of transformers, various tests are frequently required, such as short-circuit tests, no-load tests, and load tests. These tests typically need to be conducted in specific experimental environments, making the handling of transformers and their components particularly important.

[0003] Traditional transformer handling equipment mainly includes cranes, forklifts, and manual hydraulic pallet trucks. These devices can meet the needs of transformer handling to a certain extent, but they have many limitations, such as complex operation, high cost, and high requirements for the experimental environment. In addition, for some special types of transformers, such as large power transformers, the handling process is more complex and requires professional handling tools and techniques. Therefore, we propose a handling device for transformer experiments. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a handling device for transformer experiments, including multiple support frames 1, with rollers 11 at the lower end of the support frame 1, and support plates 2 between adjacent support frames 1. A connecting plate 21 is fixedly installed on the outer end of the support frame 1, and positioning toothed plates 22 distributed centrally symmetrically are fixedly installed between adjacent connecting plates 21. The positioning toothed plates 22 are inserted into the support plates 2, and positioning toothed blocks 23 are symmetrically arranged in the support plates 2. The positions of two positioning toothed plates 22 and two positioning toothed blocks 23 correspond one-to-one, and the corresponding positioning toothed plates 22 and positioning toothed blocks 23 are inserted into each other. A first threaded rod 24 that is threadedly connected to the positioning toothed blocks 23 on both sides is rotatably installed in the support plates 2.

[0026] Working principle: In use, the two support frames 1 can be spliced ​​together by the plug-in connection between the positioning tooth plate 22 and the support frame 1, and the position of each support frame 1 can be adjusted so that the position of each support frame 1 matches the shape and size of the transformer. Then, the first threaded rod 24 is rotated, and through the threaded connection between it and the positioning tooth block 23, the position of the positioning tooth block 23 can be adjusted so that the positioning tooth block 23 plugs into the positioning tooth plate 22, thereby positioning the connection between the support plate 2 and the positioning tooth plate 22, achieving the effect of positioning the support frame 1.

[0027] Finally, the transformer can be installed between each support frame 1, and the transformer can be moved by the rollers 11.

[0028] As a further description of the above technical solution: a limiting slot 26 is provided on the inner wall of the support plate 2, and a limiting plug 25 that is inserted and connected to the limiting slot 26 is fixedly installed on the outer ends of the two positioning tooth plates 22; an extension plate 27 that is centrally symmetrically distributed is fixedly installed between the two connecting plates 21, and the two extension plates 27 are inserted into each other, and a cavity 28 is provided in the middle of the positioning tooth plate 22 and the extension plate 27, and the first threaded rod 24 is provided in the cavity 28.

[0029] Specifically, the movement direction of the positioning tooth plate 22 can be restricted within the support plate 2 by the plug-in connection between the limiting slot 26 and the limiting plug 25.

[0030] By using the interlocking extension plates 27, when adjusting the connecting plates 21 on both sides of the support plate 2, the connection effect between the positioning tooth plate 22 and the support plate 2 can be improved, thereby improving the support effect on the transformer.

[0031] The recess 28 is provided inside the support plate 2. When adjusting the position of the positioning toothed plate 22 and the extension plate 27, interference between the positioning toothed plate 22 and the extension plate 27 and the first threaded rod 24 can be avoided.

[0032] As a further description of the above technical solution: A telescopic plate 31 is inserted and installed at the upper end of the support frame 1, and a threaded sleeve 33 is fixedly installed at the upper end of the support frame 1. A second threaded rod 34, which is threadedly connected to the threaded sleeve 33, is rotatably installed inside the telescopic plate 31. A limiting cavity 3 is opened at the upper end of the support frame 1, and the telescopic plate 31 is inserted and installed inside the limiting cavity 3. The support frame 1, the limiting cavity 3, and the telescopic plate 31 are all arranged in a mutually matching L-shape. A limiting insertion hole 32 is opened at the lower end of the telescopic plate 31, which is inserted and connected to the threaded sleeve 33. The second threaded rod 34 is rotatably installed inside the limiting insertion hole 32.

[0033] Specifically, when adjusting the position of each support frame 1, the second threaded rod 34 can be rotated within the limiting socket 32 ​​according to the transformer height. Through the insertion connection between the limiting cavity 3 and the telescopic plate 31, the movement direction of the telescopic plate 31 is restricted, allowing the rotating second threaded rod 34 to drive the telescopic plate 31 to move up and down through the threaded connection between it and the threaded sleeve 33, so that its height matches the transformer height, thereby improving the clamping and positioning effect of the transformer.
